Time flies and it’s already December.
A lot of things happened in the past two months. The conflict between the princes of the Southern Zhou Dynasty affected the imperial court, making the situation in the Zhou Kingdom more and more turbulent. It seemed that a coup or even a civil war might break out at any time.
As a result, some Zhou caravans were unable to return and were forced to stay in the east and west cities of Chang'an, causing hotel rents to be much higher.
The second is the new invention of the academy.
Soap and toilet soap have been widely praised since they came out. Their clean and non-greasy appearance, excellent cleaning effect, and long-lasting aromatic smell have completely defeated the previous putty.
The first few batches of soap were quickly sold out. After a slight price increase, several major merchants distributed large quantities of soap, suppressing the price again.
Since the product was selling so well, the Xuegong Patent Office took the initiative to bring Li Ang together with representatives from chambers of commerce in Luoyang, Yangzhou and other places to expand the patent authorization.
Again, only authorization, no buyout.
While Li Ang received the licensing fee, he was also worried that people's extensive use of alkaline soap might cause water pollution, so he took the initiative to raise the possible hidden dangers in this regard to the Xuegong Patent Office.
Fortunately, during the last malaria prevention and control campaign, Chang'an's canal renovation plan included urban sewer pipes insulated from underground rivers, which should not pollute groundwater in a short period of time.
The other thing is absorbent cotton - this invention for which Leon's name is hidden in the patent granted by Li Ang, is also selling well - in the form of monthly supplies.
In terms of appearance, water absorption, and sterility, absorbent cotton surpasses previous cotton, linen, and even kitchen dust.
After the palace found out that Li Ang invented absorbent cotton, they did not hesitate to purchase it in large quantities.
And after hearing that the palace was taking the lead in using it, the wealthy families in Chang'an City also followed suit. This trend spread from bottom to top and spread to ordinary people's homes.
'This can be regarded as the second step to improve Yu people's livelihood after malaria. '
With the bell of the academy ringing, Li Ang silently closed his book and walked out of the classroom.
During this period, soap, soap, and absorbent cotton brought him 20,000 guan in reservation authorization fees and 5,000 guan in patent fees, most of which were used by Li Ang to buy gold and silver.
At the same time, in order to give the outside world the illusion of being extravagant and wealthy, Li Ang also bought a large amount of valuable jewelry and clothes for Chai Cuiqiao and asked her to wear them when she went out.
As a result, the news that "Li Dalang, the top scholar in Jinchengfang Academy, doted on his maids excessively" spread like wildfire and became some kind of gossip in the market.
Some people even spread rumors, saying that Chai Cuiqiao is as beautiful as a fairy, sinking fish and falling geese, shying flowers when the moon is closed, and overwhelming the country and the city.
Chai Chai was both embarrassed and happy.
As for Li Ang himself, after devouring a large amount of gold and silver, the ink threads in his body also showed new changes - the ink threads that originally could only cover the palms of his hands can now cover the entire upper body.
Using spiritual energy to guide it, it can also cover the face to form a breathable mask with open holes.
But at the same time, the efficiency of Mo Silk's growth is also gradually decreasing - ordinary gold and silver ingots require 30% more than before to allow Mo Silk to continue to grow by the same share.
Li Ang has a feeling that when Mo Si grows to a certain stage, he will have to swallow higher quality special metals.
"Risheng, what are you thinking about?"
Yang Yu and Li Wei walked out of the classroom holding books and patted Li Ang on the shoulder.
"I'm thinking about what to eat tonight."
Li Ang said casually. Hearing the noise coming from not far away, he turned his head and looked over.
Chu tu tu tu——
Buzz——
Crash--
Model airplanes of various shapes were flying over the lawn on the other side of Chuiyun Lake in Xuegong.
Some of them are made of wood, bamboo, and some are covered with metal.
Some have single wings, double wings or even three wings.
The flying postures are also different, some are shaky, swinging from side to side,
Or it's flying left and right in the air, making turns extremely difficult.
After the inspection class two months ago, Su Feng, a doctor of science, applied to the mountain director to open an additional elective course called pneumatics (that is, aerodynamics), specifically studying how to make aircraft models with better performance.
Many senior students have signed up for this course, and making aircraft models according to Li Ang's method has become a new trend in the academy in recent times.
However, the aerodynamic layout of the model aircraft they produced was not very good. Many of them lost control while flying and crashed on the lake.
"Another one crashed."
Yang Yu curled his lips and said: "I feel like if I bump into someone one day, these model airplanes will be banned for the sacrifice of wine. Just like flying swords, they can only be played in the martial arts field."
"Speaking of Risheng, why didn't you go to the qi class?"
Li Wei asked curiously: "If you go, Dr. Su Feng will definitely give you a lot of credits - after all, this course was discussed between you and him."
"Well... let's forget it. I have to do other things."
Li Ang waved his hand and said.
The aircraft models of senior students did not fly as well as him. On the one hand, their aerodynamic performance was low.
On the other hand, their sensitivity to fine gold threads is not as good as that of Li Ang.
'Maybe this is also the effect brought about by Mo Si. My ability to sense and control special metals is already higher than that of some monks in the Rain Listening and Cloud Patrolling Realm.
Although the total amount of spiritual energy is still in the hidden state. '
Li Ang thought silently, 'Maybe it's time to choose a time to reasonably show that he has reached the hiding state. '
A few days ago, Pei Jing was the first to break through to the hiding place, followed closely by He Fanshuang, and each received a credit reward.
The academy’s cultivation requirements for freshmen are to break through to the hidden state within six months to one year after enrolling.
Anyone faster than this standard will get credits.
After advancing to the Hidden Realm, you can finally use some relatively "practical" spells, but this also means that new students need to choose a path that suits them.
Talisman Sword Mind Body, which one or two should I choose...
Li Ang thought about this problem, walked out of the west gate of the academy, and the three of them took the Yang Yu family's carriage back to Chang'an - the weather was cold, so Li Ang stopped riding the maroon horse to get off school.
The carriage drove into the far west gate of Chang'an City and passed through Yiningfang.
Yang Yu and Li Wei were talking about which path they would choose if they were promoted to the Hidden Realm. Li Ang raised the car window and stuck his head out to breathe in the cold fresh air.
His eyes passed between buildings with white walls and black tiles. Li Ang accidentally caught a glimpse of a building. He subconsciously retracted his head and called the parking man to stop the carriage.
"What's wrong Risheng?"
Yang Yu thought something was wrong and asked subconsciously.
“Wander around the Jingsi Temple.”
Li Ang thought about today's date, jumped off the carriage, and stood in front of the temple with white walls and black tiles.
Nestorianism is a branch of Christianity. Jingsi is a church in a sense.
At this moment, a group of Persians in white robes were distributing eggs, candies, vegetables, wooden crosses, and paper scriptures to the citizens queuing outside the temple.
There were also more fervent prayers coming from the temple than before.
Li Ang declined the invitation of the temple staff to lead a tour, and walked into the temple with Yang Yu and Li Wei who were not sure why, looking around.
Today is Christmas.
An inexplicable emotion arose in Li Ang's heart. The Jingsi's white walls and black tiles, with its cornices and brackets, were no different from the Chang'an pavilions. There was even a main hall.
What hangs on the walls of the Main Hall is not the Madonna, but the portraits of the emperors of the Yu Kingdom - these paintings were awarded to Jingsi by the royal family.
"...I, the three-one wonderful body of the non-original God Araha, mark the cross to determine the four directions, encourage the original wind to generate two qi, the dark sky changes and the sky and the earth open, the sun and the moon move day and night, the craftsman completes all things and then establishes the beginning people..."
From the depths of the temple came the rhythmic chanting in Chang'an Mandarin.
This is not a Nestorian practice secret book, but a "Genesis" verse recited by a Nestorian priest (priest) - God said that there was light, and there was light. He separated light from darkness and created all things in the world and human beings... .
An unreal feeling arose in Li Ang's heart. It was obviously Christmas, but there were no evergreen trees, Christmas stockings, Christmas carols and Christmas gifts.
Still can't find the shadow in my memory.
Li Ang recalled the scene in the memory fragments and shook his head with some disappointment.
"Do the three young masters of the academy have to wear crosses and listen to the lectures?"
Gentle Chang'an Mandarin sounded in the corner of the hall, and a young monk with Persian appearance and curly hair came forward with a friendly and kind attitude. Judging from the costume, he is still a priest.
"Don't bother the priest. We are here to visit. Let's go now."
Li Ang just wanted to experience the Christmas atmosphere in the memory fragments, so he declined.
The kind smile on the young monk Jing's face did not diminish, and he continued: "It is best for the three young gentlemen to stop for a while, listen to the sutra, and calm down.
I see that the three palaces have turned black, and there seems to be blood and light in recent days. "
A symbol of blood and light?
The expressions on the faces of Yang Yu and Li Wei were quite strange. A Persian Jing monk told them seriously that the hall was dark and they would have bad luck recently. This was very inconsistent no matter how they thought about it.
