"yes."
Li Ang nodded.
"Xi Yangyu likes to follow others, but he shouldn't dare to lie about enrolling in the academy."
Yan Yundang groaned and said, "Then, little doctor Li, what are your plans for the future?"
"Junior still wants to give it a try."
Li Ang said: "If you don't give it a try, you will still be a little unwilling after all."
"good."
Yan Yundang nodded and said: "But don't be discouraged even if you don't pass the exam. The Zhongsi Institute of the Ministry of War is still open. I will just write a letter when the time comes."
"Then thank you so much, Duke."
Chujiyuan is an institution where the Ministry of War teaches the way to practice. It also teaches talismans, techniques, swordsmanship, and nen, but more importantly, it teaches physical training.
Since Yan Yundang was too weak to stand for a long time, Yan Lin had someone help him back to the house to rest, and he personally sent Li Ang out of the Duke's Mansion to thank him again.
After Li Ang returned to Huaidefang Hotel, early the next morning, the old housekeeper of Duke Yan's mansion came to visit in a carriage, saying that Yan Yundang's condition had improved significantly and he could now eat.
To express gratitude, I would like to present 10,000 yuan of flying money to Li Ang.
Li Ang insisted on only accepting 4,000 guans - the reward posted by the Duke of Yan on the public notice board at the city gate was 5,000 guans.
The old housekeeper said that ten thousand guan was the amount set by Yan Yundang and could not be changed. In the end, he couldn't resist Li Ang, so he had to compromise.
Li Ang accepted four thousand guans of flying money, and the remaining 6,000 guans were converted into various physical objects of equivalent value - that is, special alloys, jade, wood, minerals, and blank talismans that were occasionally sold in Chang'an Auction House.
Exotic materials are an important part of spiritual practice.
Special alloys and wood can be used to create flying swords.
Jade and minerals can assist in performing spells,
Talisman papers made of different materials have different manifestations of the power of the talisman.
Even warriors who refine their bodies must use medicine, animal blood and even other materials when sharpening their muscles and bones.
Six thousand strings, say more, but not too much, say not much,
Several private auction houses in Chang'an have Zhenfusi backgrounds behind them. They have many rules and are only open to familiar monks. Ordinary people with six thousand guan cannot buy anything, or they have to pay more to buy it.
Li Ang said that he wanted to use those materials to try to make homemade medical devices, so he didn't seek more or more refinement, just simplicity.
The old housekeeper did not brag about his promise directly, but said that he needed to go home and ask Yan Yundang and Yan Lin for instructions.
That night, Yanfu's carriage came to Huaidefang Hotel again and unloaded several large boxes from the carriage.
In each box, a wide variety of materials are packed into categories according to Li Ang's requirements. The total price is exactly six thousand guan.
Of course, this is the price for Yan Yundang,
If an ordinary monk or a newly admitted academy disciple wants to buy it, he will need to pay at least 50% more. If he goes to Chang'an Ghost Market, the price will even double.
The ghost market refers to a giant cave system composed of dozens of underground rivers forty miles east of Chang'an City. There are waterfalls, lakes, peaks, and caves.
There are often people from all walks of life hiding in the depths of the ghost market, including fugitives, wanted defecting monks, bandits who have stolen goods that need to be disposed of, and black marketeers who risk their lives for money...
They formed an underground kingdom under Chang'an, where they sold all kinds of strange goods and exchanged what they needed.
Even dangerous monsters and monsters can be sold at a clear price. Multiple forces are intertwined, forming a vast network of interests.
And when the government tried to launch a crackdown,
These people will dive into the intricate underground rivers and escape far away.
The interior of the cave is deep and long, with complex terrain and hundreds of underground rivers, with countless entrances and exits like a honeycomb.
In the pre-Sui Dynasty, someone once threw a hundred painted wooden boat models into the underground river. The furthest wooden boat even appeared in Poyang Lake, 1,200 miles away.
Moreover, due to the irregular rise and fall of underground rivers, rivers are often invaded, diverted, or even collapsed.
As a result, the map will become invalid every once in a while, making it difficult for the Yu State army and monks to enter and destroy it.
The Zhenfu Division has no choice but to completely destroy the ghost market while protecting the underground river from being destroyed - the underground river extends in all directions. If someone puts strange poison into the river, the consequences will be extremely serious.
They had no choice but to send troops to guard the exits of several major caves on the surface, and the two sides reached a certain tacit understanding.
As long as the people in the ghost market don't go too far and do things like selling people on the surface, Zhenfusi will not go down to the cave easily.
After Li Ang got four thousand guan of flying money and various materials worth 6,000 guan, he first pacified Kangfang, settled Jiao Cheng's previous account, and destroyed Youduzhi's slave registration.
Song Shaoyuan and You Douzhi were extremely grateful for this and insisted on returning the five thousand guan to Li Ang - Song Shaoyuan still had some money left, and You Douzhi had saved about 2,000 guan himself, but Li Ang refused.
You can't ask Aunt Song, who is far away in Zhenzhou, to send extra money just for this money.
Simply let Song Shaoyuan and You Douzhi live a good life in the city of Chang'an - there will be Jinshi exams in Chang'an next February, and they are already here, so they might as well wait until Song Shaoyuan finishes taking next year's Jinshi exams before making plans.
After all this is taken care of, there are only four days left before the final exam of the academy.
In Huaidefang Hotel, Li Ang looked at the dazzling array of materials on the table and murmured: "If this doesn't work, then we can only try our luck in the ghost market..."
"Master,"
Chai Cuiqiao looked over curiously, "What are you going to make with these things?"
"antenna."
Li Ang smiled and said, "An antenna that can conduct spiritual energy."
He brought a thick blank book and placed it on the table. He prepared an inkstone, ink, and pen.
Then he took a few steps back, picked up the first material - the purple Dushan Jade, held both ends of the jade with both hands, held it flat in front of him, and silently recited the words of the "Shangqing Inspiration Chapter".
Just like the previous test, every time Li Ang introduced spiritual energy into his body, his brain would tingle slightly.
This should be what Xi Yangyu said, the Sword Hexagram with the Skull Broken.
"Without holding any material, the pain level is 1."
"When holding the purple Dushan Chalcedony, the pain level is 1.3."
Li Ang put down the Dushan Jade, wrote two lines on the booklet, and then picked up the second material, a small piece of Chenyin wood from Youzhou. As before, recite the "Shangqing Inspiration Chapter" silently, feel the tingling pain in the brain when the spiritual energy enters the body, and record it in the book.
"Youzhou Shen Yin Wood, pain level, 1.2."
Li Ang tested different materials one after another, taking a break every once in a while.
Chai Cuiqiao watched from the side with her eyes wide open, and gradually understood as she watched, "Master, are you recording the degree of pain when holding these things?"
"Um."
Li Angfeng Danyun nodded lightly and explained casually: "Every item in the practice world has the saying of 'the nature of things'.
Different substances have different affinities to the spiritual energy of heaven and earth.
For example, fine gold and thousand-year-old peach wood have a higher affinity for the spiritual energy of heaven and earth than ordinary stones.
The monks use a certain amount of spiritual energy to pour into fine gold and thousand-year-old peach wood, making it easy to levitate and move in the air according to thoughts.
However, the same total amount of spiritual power can only make the rocks fly slowly and cannot perform maneuvers.
This material property should be like thermal conductivity and electrical conductivity. "
Chai Cuiqiao asked curiously: "Conductivity?"
“Conductivity is a measurement of a substance’s ability to transmit electrical current.
You can simply understand that in rainy weather, Lei prefers to chop metal rather than stones. "
Li Ang said casually: "According to whether a substance has electrical conductivity, substances can be divided into conductors, semiconductors and insulators.
If you put it on the spiritual level,
Fine gold and thousand-year-old peach wood are excellent conductors of spiritual energy.
The special armor created by Zhenfusi that can isolate spiritual energy is an insulator of spiritual energy.
Between aura conductors and insulators, such as jade, alloys, stainless steel, etc., they are aura semiconductors. "
The Academy had discovered a similar concept three hundred years ago and developed dozens or hundreds of spirit gathering formations.
These spirit gathering arrays are made of different exotic materials arranged according to certain rules, which can speed up the flow of spiritual energy in the space.
This will then speed up the efficiency of cultivation below the Zhuxiao realm.
However, because the sources of many materials have gradually decreased, or their quality has deteriorated, the efficiency of transmitting spiritual energy has continued to decrease, and the utilization rate of the spirit gathering formation has also become less.
"Uninitiated monks before the Qi Sensing Realm, holding alien materials, can slightly speed up the flow of spiritual energy in the body, but the increase is almost negligible."
Li Ang said: "However, the Broken Sword hexagram in my head...how to say, is quite sensitive.
Even a slight change in the speed of spiritual energy flow can be converted into clear pain sensation.
Therefore, it only requires continuous testing to record the specific spiritual energy transmission efficiency of each material.
What I am doing now is to find the most suitable wire just like I am looking for lamp materials. "
Li Ang raised the corners of his mouth slightly proudly, and seeing that Chai Cuiqiao still had a worried look on his face, he smiled and patted her palm gently, "It's okay, I know it well and won't hurt myself.
Although it is still unclear what the essence of the mysterious and mysterious spiritual veins is, the principles should be similar.
If the spiritual vein in my head is naturally broken and cannot bear the function of transmitting spiritual energy, then I can just connect an external one myself.
Find the most suitable material, connect the broken spiritual veins on both sides, and re-form a complete circuit. "
The final exam time was approaching, and Li Ang's actions were at full efficiency. Apart from eating and sleeping, he was testing and looking for suitable spiritual energy conductors, and made countless samples for this purpose.
————
"I had the right idea."
In the study, Li Ang was alone, looking through the items on the table.
Today is the last day before the final exam. Chai Cuiqiao was afraid of affecting Li Ang, so she moved to Ji Linglang's big house in Huaidefang to give Li Ang space to think and experiment alone.
After this period of exploration and exploration, Li Ang determined that the severed sword was probably in the frontal lobe area and below the superior sagittal sinus.
Use spiritual energy conductors and semiconductors,
Antennas, hats, headbands, hairbands, hairpins and even glasses that can be worn on the head have been made.
These jewelry made of conductors and semiconductors, when worn on the head, can indeed perform part of the spiritual energy transmission function and relieve the pain in the head.
"After testing so far, the conductor with the highest spiritual energy transmission efficiency is fine gold."
Li Ang picked up a gold wire twisted into a ring and murmured: "However, even fine gold is still unable to perfectly conduct spiritual energy and eliminate the stinging pain in the head."
If you think of the spiritual energy conduction efficiency as electrical conductivity,
Then fine gold is already the best conductor that Li Ang can find currently.
If this still doesn't work, then there are only two last methods left.
"One, implant the spiritual energy conductor directly into the brain."
Li Ang said silently, "The location of the broken spiritual vein is the frontal lobe under the skull.
The bones and skin of the head themselves will act as obstacles, so the effect of the headgear is not as good as expected.
Maybe the fine gold wire could be implanted directly under the skull to form a circuit - for safety reasons, it would be best to wrap the fine gold wire with an insulating layer.
But the problem is...there are no conditions for craniotomy now. "
Not to mention whether Li Ang is the only neurosurgeon in the world,
Even he himself would not perform craniotomy on others without hemostasis, disinfection, and anesthesia.
That's basically no different than murder.
"The second method is to find a superconductor that is more efficient in transmitting spiritual energy than fine gold..."
Li Ang muttered to himself and stood up from his seat, "If you give me enough time and materials, there may be hope of finding it out."
There is not enough time. There are less than eight hours left before the final exam of the academy tomorrow.
"Can I only wear this gold ring to take the exam?"
Li Ang sighed softly, packed up the things on the table, put them in the box and locked it.
He put the golden ring into the medicine box, sighed, and prepared to go out to relax.
As soon as he left the house, he heard a knock on the door.
"Who?"
"Is Li Ang at home? I am a doctor of arithmetic from the academy."
PhD in mathematics?
Li Ang raised his eyebrows in slight surprise, walked forward and opened the courtyard door.
Standing outside the door was a short, fat middle-aged man, followed by three young scholars.
"Are you Li Ang?"
Chao Wenyuan took off the jade plaque from the Academy with the inscription on it from his waist and said, "I am Chao Wenyuan, a doctor of arithmetic in the Academy, and I was also the one who judged your papers in the first test that day."
"Junior has met Dr. Chao."
Li Ang cupped his hands, feeling a little strange in his heart. Why did the doctor of arithmetic from the Academy come to see him at this time?
It’s impossible to reveal the content of tomorrow’s exam, right?
"I'll just say it directly. I'm here to reveal the content of tomorrow's exam."
Chao Wenyuan said seriously: "Tomorrow, in the final exam of the Academy, the spiritual pulse talent will definitely be tested, and the candidates will be required to use their own spiritual power to solve problems.
So I hope you can withdraw voluntarily. "
"Um?"
Li Ang was slightly stunned, but then heard Chao Wenyuan continue: "I have read the hexagrams of Xi Yang Yupan, and there is indeed no problem.
All the skull-broken sword hexagrams in history have no way to explain them.
Forcibly introducing spiritual energy into the body can cause damage to the mind and make the person stupid and clumsy. Severe cases include bleeding from the seven orifices and rupture of the skull.
You are extremely talented in arithmetic,
Although the academy stipulates that those with unqualified spiritual pulse talents cannot enter the school, I have already argued for you in front of the mountain chief and Jijiu.
I have secured a place for you as a day student. "
Li Ang said in surprise: "Day study?"
"That's right, your name is not on the student record, but you can use your badge to enter and leave the classroom and audit classes, but you cannot live in the academy, nor can you leave places other than the teaching pavilion."
Chao Wenyuan said seriously: "The Academy rarely accepts day students in its history.
You have excellent talent in arithmetic. It is a pity that you cannot enter the academy because of your incomplete spiritual veins. "
Li Ang was silent for a moment, and then bowed his hand again with great sincerity, "The student thanks Dr. Guochao, but the student... still wants to give it a try tomorrow."
Chao Wenyuan frowned slightly, and the young student next to him couldn't help frowning and said: "Why are you so stubborn? Do you know that the teacher has gone to the mountain leader several times to make trouble about you..."
"alright."
Chao Wenyuan interrupted his disciple's words and stared at Li Ang seriously, "Have you thought about it?
Apart from these restrictions, what day students learn is no different from that of ordinary students.
It's just a piece of academic record missing. "
Li Ang still sincerely handed over his hand and said nothing.
He knew the efforts Chao Wenyuan had put in. The Academy was the best academy in the world, and even the descendants of princes and nobles had to follow the rules and enroll based on their abilities.
I don’t know how much trouble the quota for a day student will cause and how many people will oppose it.
But...that piece of paper is really important.
Without the status of a genuine academy disciple, Li Ang's plans to create inventions, promote modern scientific methodology, and even implement real surgical operations will encounter a lot of obstacles.
It is even more impossible to realize his wish to ensure that people are well fed and clothed, the elderly are provided for, the young are educated, the poor are supported, the poor are helped, and the sick are treated.
Only by being admitted to the Academy in good faith can other people's mouths be silenced and Li Ang's plan better implemented.
"All right."
Chao Wenyuan sighed softly, not too surprised, and laughed at himself: "I guess, at your age, you can have such arithmetic attainments.
Naturally, he is a person who sticks to his own opinions.
but..."
Chao Wenyuan suddenly became solemn and said in a deep voice: "If tomorrow's exam really doesn't go well, it's best to withdraw - I will apply to the mountain chief to reserve the quota for you as a day student."
"Junior thanks Dr. Chao."
Li Ang sincerely thanked Chao Wenyuan and watched the latter wave his sleeves coolly and turn around to leave with his disciples.
"What a...good teacher."
Li Ang said sincerely that Chao Wenyuan, like Pu Liuxuan, both have the temperament to truly teach and educate people.
Advocating rationality, focusing on practicality, and respecting knowledge, the Academy is such a place.
'I will pass the exam as a student. '
Li Ang muttered something silently in his heart, closed the courtyard door, and walked towards the south.
The sunset is just right, the sunset is gorgeous,
Li Ang felt the evening breeze in Chang'an, listened to the sounds of life in the city, took a slow walk, and gradually cleared away the distracting thoughts accumulated in his mind.
As soon as I walked out of a secluded alley, I heard a "boom" from ahead.
A heavy carriage parked at the end of the alley,
The cloth on the car window was opened, revealing a charred and pale face, as well as the powerful crossbow in his hand, pointing at Li Ang.
"Little Doctor Li,"
Jiao Cheng said hoarsely, as if he was holding back the pain, "Please get in the car."
