He Qi, the heir of Taoism, is the youngest among the old masters and has the best temper. He reads a book and a cup of tea all day long, contentedly.
When he was in the Imperial College, He Qi taught "University" and "Shangshu".
After arriving at the Four Seasons Academy, he stopped teaching Confucianism and taught swordsmanship. In his words, it means that in the future, when young students go out to have their own adventures, Confucianism is to allow them to reason with others and convince others with reason. As for swordsmanship, it is to just rely on reasoning with others. When you are not very convinced, you can use one or two tricks. The purpose is that it doesn't matter if you are convinced or not, you must beat it until you get it.
In addition to swordsmanship, He Qi will also teach some miscellaneous subjects, such as pharmacology, stargazing, divination, mountain geography, etc.
These old masters all have areas of expertise, such as Yin-Yang Studies, Legalism, Military Strategy, Mohist Machinery, Agriculture, Zongheng, etc. He Qi is the only one who knows everything and knows everything. But compared to several other old masters, he certainly doesn’t. They are so "sophisticated" that, to put it simply, they have learned a lot of knowledge.
This does not mean that He Qi is miscellaneous but not good. If other old masters are "100 points" in their respective fields and all other fields are zero points, He Qi is "90 points" in every field, or even "Ninety-nine points."
Han You sat back on the stone bench, his face a little confused, and he didn't say what he wanted to ask He Qi to do.
Seeing Han You being so hesitant and solemn, Teacher Po smiled slightly and excused himself.
It’s really not that Han Youxin is inferior to Zhai Ge, but he still hesitates when the matter comes.
"If Shaoyin hasn't made up his mind yet..."
"I've made up my mind!" Han You gritted his teeth and said, "Gunpowder."
"Gunpowder?" He Qi's expression changed slightly: "Grease, rosin, sulfur?"
"No, no, no, no, that's for fire attack."
What He Qi was talking about, Han You knew, this was the fire arrow used by the two armies at the northern and southern border. It was made of a mixture of grease, rosin, and sulfur and tied behind the arrow. After being shot, it would ignite when exposed to an open flame and would not go out for a long time.
""Warring States Policy" records that the alchemists offered the elixir to King Jing. Emperor Wu of the Han Dynasty also had a delusional wish to live forever. The people widely accepted alchemists and even made elixirs themselves. Going further, the First Emperor sought immortality, and a large number of alchemists entered the palace to refine elixirs. Many of them The method used by alchemists to make alchemy is called fire method, right?"
He Qi took a deep look at Han You and nodded slightly: "Yes, fire method alchemy. I never thought Shaoyin would be involved in such a wide range of fields. Many alchemists back then came from Taoism. This fire method alchemy is also my Taoist skill."
"Can you tell me about this fire method for elixir refining?"
"What's wrong? It's nothing more than forging, refining, burning, melting, pumping, flying, and improving."
The so-called forging means heating at high temperature for a long time.
Refining, heating dry matter.
Moxibustion, local baking.
Melt, melt away, melt into liquid.
Smoking, that is, distilling.
Fei, this is more mysterious, also called Sheng, sublimation.
Excellent, the last step is to heat the material to deform it.
In fact, this completely involves "chemistry" knowledge, Han You listened absently.
He Qi explained patiently, showing unabashed disdain during the explanation process, not for "chemistry", but for the extremely ignorant method of so-called alchemy by early alchemists.
The "fire alchemy" mentioned by Han You does not use open flames in this process.
After He Qi finished speaking, he asked in confusion: "What does this have to do with the magical weapon Shao Yin mentioned?"
"Those alchemists always have accidents during the process of refining alchemy, with loud noises and burning flames."
"good."
He Qi laughed dumbly: "Shao Yin usually goes straight and rarely beats around the bush, but now he is hesitant. It seems to me that he still hasn't made up his mind."
"When dried, sulfur, saltpeter, and charcoal are mixed in a certain proportion. It is powder at first, and then granular. It is used as medicine and gunpowder."
"medicine?"
"Yes, medicine, the magic medicine that will send all thieves to hell."
He Qi seemed to have thought of something, and after pondering for a while he asked: "What is sulfur?"
"Stone flow yellow."
"Shiliu Huang in "Fan Zi Ji Ran"?"
"good."
He Qi looked puzzled: "I seem to know what Shao Yin is talking about. The divine thunder fell from the sky and not a single blade of grass grew. Yes or no."
"As expected, you know." Han You nodded repeatedly: "The power is ten times, a hundred times stronger than what Mr. He knows."
In fact, there is no conclusion about who first invented "gunpowder". The earliest one said it was Ge Hong. During the Eastern Jin Dynasty, sorcerers were popular. Ge Hong was very good at this art. He was also named a Marquis of Guannei for his alchemy. His book "Bao" There is a recipe for gunpowder in "Pu Zi".
However, this formula is not charcoal, sulfur, and saltpeter. Instead, it records the method of processing realgar. Mix xuanxian intestines, saltpeter, and realgar in a certain proportion. Xuanxian intestines contain carbon, and realgar contains sulfur, which is similar to gunpowder. The formula saltpeter, carbon, and sulfur are exactly the same.
But when gunpowder really appeared, it had to be during the Spring and Autumn Period and the Warring States Period, when warlocks were making elixirs all day long.
It is also said that it was invented by Sun Simiao, the king of medicine in the Tang Dynasty, and it is recorded in some medical books and notebooks.
The period when firearms were truly used in the military was the Tang Dynasty, when rockets, fireballs, explosives and other firearms began to be used in the military. In the late Song Dynasty, fire blunderbuss, thunder cannons, and thunderbolts completely changed the way of warfare.
There is no need to bury the dead here... No, let’s just mention the Qing Dynasty by the way.
During the Yuan Dynasty, gunpowder was spread all over the world by the Persians. However, the isolation of the Qing Dynasty caused the development of science and technology to completely stop. Gunpowder technology no longer made any progress, but was carried forward by the West.
"Once this magical weapon is made, it will completely change the general trend of the world. Within five years, no foreign enemies will dare to disturb the border towns. Five years later, with this weapon, we can drive straight into the grasslands, into Yingdao, and anywhere within sight. We will turn them all into our Great Zhou territory, pacify the north and accept them as our Great Zhou territory, and it is not impossible to invade North America in thirty or fifty years."
“Where is North America?”
"Well...North America is also north, it's all north anyway."
He Qi pondered for a long time, and seemed to have understood what Han You was talking about, and there was no excessive look of shock on his face.
Han You continued: "There is still exactly one month left for the martial arts practice. Before noon tomorrow, I will have people build a temporary residence twenty miles away from the back mountain. His Highness Youwang will personally lead people to guard the perimeter, with a radius of five miles. People and animals are not allowed to approach, even Mr. He..."
"You know, Shao Yin is relieved. How can I, with such a heavy responsibility, walk around and leave at will?"
He Qi blinked: "After the matter is completed, Shao Yin will not kill people and silence them."
Han You was overjoyed: "Uncle He, please stop making trouble. If I, Han You, were like this, you would also..."
"If this thing is really as sharp as you say." He Qi interrupted lightly: "You should kill and silence it."
Han You was startled: "Don't make such a joke. You don't want to commit suicide directly after making it. If it's Aunt Jiang, I'd better let someone do it."
This time it was He Qi's turn to laugh, stood up and saluted: "The old Taoist has lived up to Shao Yin's orders, just wait for the letter."
"Mr. Laohe is here."
"Due to your due diligence."
Han You personally sent He Qi out of the small courtyard. The latter had to simply pack his bags and then go to "retreat" to create things.
"Go and call Zhou Yan."
"yes."
