Chapter 102: Academic Questions

"Blindly improving the technology of engraving will not work," the kid shook his head: "The student thought about it, should make a fuss about the barrel, the flintlock pistol we are using now is a barrel forged from mille-feuille steel, although durable, but in fact it still can't escape the nature of iron ore, when the same as other inventions in the uncle, add other minerals to synthesize its properties, so that its use is greatly improved, and then increase the length of the barrel, the engraving of the Yin pattern is now carved on the front, it is better to try the reverse carving, so down, Students felt that flintlock pistols could increase their service life after use, and that this method could also be used on newer rifles. ”

Chen Cao nodded with satisfaction, these knowledge points were all things he had never talked about, and it was a good thing that some students could understand them now: "What's your name?" ”

"Student Lin Liangcai, I've seen my uncle." Lin Liangcai gave Chen Cao a military salute.

"Who's your squad leader?"

A student at the bottom said, "Uncle, he is the class leader." ”

"No wonder..."Chen Cao nodded: "Your knowledge is very good, what my college wants is a talent like you who study hard work, Lin Liangcai's learning attitude is worth learning from, the teacher in the hall wrote down that Lin Liangcai's academic research is feasible, and ten taels of scholarships are issued to encourage you." ”

The students below were in an uproar, although they all knew that there were teachers who talked about scholarships at the beginning of the establishment of the college, but no one thought that a small academic study would have so much money, and ten taels of silver was the total income of their parents in the army and the workshop for five months, who did not envy it.

"Student Uncle Xie." Lin Liangcai hurriedly saluted again.

"You can't just be limited to guns," Chen Cao amplified his voice: "In addition to studying in the future, your academic research should be broadened and involved in many fields, otherwise we will only have guns and cannons in the future, and nothing else will be accomplished, and we must not learn from the Donglin Party." ”

"Yes..."

Students in class answer aloud together.

After the first class finished speaking, Chen Cao immediately walked into the second class and started the lecture as before, and then said: "Regarding the steam problem that Benbo talked about, you can discuss it carefully after class. ”

"Uncle," one of the students stood up, "the student knows what Uncle means." ”

"Oh," Chen Cao was about to turn around and leave: "Report yourself, and then listen carefully." ”

The student arched his hand: "Student Cao Shiyun, my father is Cao Xiang, the right guard," Cao Shiyun said and gave his hand again: "The student thought about the steam problem that the uncle talked about, and it should be the power of the steam hitting the lid to drive other things to rotate, such as the water hammer in the workshop or the iron car that the uncle talked about. ”

Chen Cao raised his eyebrows, and said that the ancients had high wisdom, and they were just limited to the bottleneck of things, as long as someone ordered it, the Ming Dynasty could produce many inventors such as Einstein and Edison: "You go on." ”

Cao Shiyun continued: "Uncle talked a lot before, and the students thought about it below, the water hammer drive in the workshop is because of the rotation of the wooden gear, which can pull the water hammer, if the uncle talked about the iron car, then the use of wooden gears will definitely not work, and the students think that they can use iron gears." ”

"That's right," Chen Cao nodded, then sat on the edge of the podium, and looked at Cao Shiyun carefully: "But you have to think that the iron car is the size of the carriage at most, if it is measured by the small teeth of the workshop, how big are the gears used on the iron car?" ”

Cao Shiyun seemed to have thought of it a long time ago: "If you reduce the gear, you can install it on the iron car, but uncle, the student is thinking that it is feasible to use hydraulic power in the workshop for simple gear rotation, but on the iron car, his power problem still needs to be considered." ”

Chen Cao crossed Erlang's legs: "I teach all of you a big knowledge point, do research, you must do a little, make bold assumptions, carefully verify, your ideas can be wild, but the actual action must be tested little by little, don't go your own way, otherwise something big happens, Ben Bo will not discuss with you." ”

Cao Shiyun got Chen Cao a little bit, so he said, "Uncle, the student thought of it again." ”

"Speak." Chen Cao smiled.

Cao Shiyun drew a few strokes on rice paper with a brush, and then held it up: "The water hammer of the old-fashioned workshop is wrapped in a wooden house by the master craftsman, and the gears rotate soundly but small. ”

Chen Cao was very satisfied with this kid, so he nodded: "That's right, Ben Bo thinks so too, how are you going to solve the power problem?" ”

Cao Shiyun frowned, and immediately reacted: "The student thought of it," and then bowed to Chen Cao: "Uncle is a good teacher, the student admires, no wonder Uncle gave us a lecture on the steam problem first." ”

Chen Cao felt that his tips were very useful: "Let's talk about it carefully. ”

"Yes," Cao Shiyun arched his hand again: "The teachers showed us that the full kettle would be lifted up after it was opened, and the students were puzzled. ”

"That's right." Chen Cao stood up and drew a few strokes on the board: "After the water is boiled, the steam boiling will be lifted up by the things on it, and the power of the jacking up is called steam power, and you have all seen it, the water of the kettle can lift the lid of the kettle, if the water in the big pond in the yard is boiled, you think it can hold up something." ”

Seeing that even Cao Shiyun was meditating, Chen Cao smiled and said, "Ben Bo just said, a bold assumption. ”

"You can jack up the cows in the backfield..."

"Jack Master Zhang up..."

"Hahaha..."

"Roofing up the house..."

The students were talking nonsense, and Chen Cao looked at Cao Shiyun curiously: "Cao Shiyun, what do you think?" ”

Cao Shiyun raised his brows, his eyes lit up: "Uncle, you can turn the gears..."

"Hahaha..."Chen Cao laughed loudly, and just when Cao Shiyun thought he was wrong, Chen Cao said: "That's right, you can turn the gear, then let me ask you, what can it do after the gear turns?" ”

Cao Shiyun said as if he had a heart booster: "Uncle, the gears rotate and drive the iron car to move, this is the power that Uncle said." ”

"Yes," Chen Cao nodded solemnly: "Cao Shiyun is right, this is the source of steam power." The Army Academy set up by Benbo is not only to teach military art, but also to miscellaneous, and if we want the Ming Dynasty to prosper, we have to rely on this. Saying that, Chen Cao returned to the topic, staring at Cao Shiyun and said, "What do you think should be done with the steam power source on the iron car?" ”

Cao Shiyun said: "The only thing that students see is water and firewood, and if it is used on the iron car, it can only use a little better charcoal, but it is a precious thing, and it is very wasteful to use it on a large scale." ”

Chen Cao shook his head: "It is not good to burn charcoal, its firepower and burning durability are not enough, there is a black and dark thing in the territory of Shanxi Buzheng Envoy, the locals call it 'black ink stone,' the Taixi people call them 'coal', its burning power is very large, the combustion power is long-lasting, the only drawback is that the smoke and dust are too large, but now it is the only way, use it, hehe, guess how far the iron car can run?" ”

"As much steam as you can, you can go as far as you can." Cao Shiyun replied.

Chen Cao nodded, and then said: "Ben Bo gave you a suggestion to the whole class, after the miniature gear is improved, it must be wrapped in iron sheets, Ben Bo named it and called it 'engine', as for how big the engine can be, that is what you have to study, and the scholarship is awarded to those who love to study invention and creation." ”

As he spoke, he looked at the teacher outside the door and said, "Remember, Cao Shiyun has made meritorious contributions to his research, and he will be given a scholarship of ten taels to encourage him." ”

The whole class was in an uproar, ten taels of silver was not a small amount, Chen Cao turned his head to look at all the students in the second class, and then said with a smile: "If anyone can study or draw the engine of the iron car, Ben Bo will directly grant him the official position of hereditary hundred households." ”

This is terrible, these children of homeless people and untouchables will not be able to be officials all their lives, and now they can get hereditary official positions just by engaging in a small invention and creation, which is terrible, and they are ready to do a big job in these things.

Chen Cao stayed in the academy for most of the day before leaving, Zhao Xin followed behind him and asked carefully, "Uncle, can these things work?" Last time, Father Tong told his subordinates about the Almighty Lord, who can save the world. ”

Chen Cao stood still and squinted at Zhao Xindao: "Are you a religious kid?" ”

Zhao Xin saw that Chen Cao's eyes were not good, and he immediately looked righteous: "The subordinates should believe only in the uncle, and his immortals in Taixi can't control our Daming if they want to." ”

Chen Cao nodded with a smile on his face, and then said, "Your kid's mind is still flexible, if you believe in their teachings, you don't have to follow me anymore." ”

Zhao Xin was shocked, he never imagined that Chen Cao didn't like the Taixi Sect so much: "Uncle... Uncle, since you don't like their immortals so much, why do you still let them believe in religion, the scouts in the city have collected more than 50,000 people who believe in their Christianity in Jinling so far. ”

"So much?" However, after thinking about it, the Taixi people's ability to fool people is still very powerful, so Chen Cao asked, "By the way, how about letting you send someone to spy on them?" ”

Zhao Xin arched his hand: "Uncle is a god, a total of more than 130 letters were intercepted, and the spies opened them one by one, of which more than 40 were drawings of flintlock pistols and cannons designed by Uncle, as well as descriptions of other weapons. ”

"How did you deal with it?" Chen Cao frowned.

Zhao Xin said with a smile: "According to the uncle's request, my subordinates found a lot of spies who were proficient in Taixi script, and then asked them all to quietly revise their letters into homely condolence letters. ”

Chen Cao also laughed evilly, patted Zhao Xin's shoulder and said, "You have done a good job in these things, and you deserve praise, but you must remember that if anyone shows signs of slipping away, take it directly." ”

"My subordinates understand..."
