"Young Eunuch Yan, in fact, this seesaw has a university question in addition to playing." Gu Qing hurriedly said, "You see that this length is related to the force, and this is called leverage. ”

"My old man naturally understands this!" Yan Liben said, "Now that I've read it, it's time to talk about the new firearms." ”

"Actually, there's a bookstore here." Gu Qing took Yan Liben to the small study, and now Kong Yingda had just finished class.

Yan Liben hurriedly saluted: "The younger generation has seen the old master. ”

"Hehehe......" Kong Yingda smiled and was in a good mood, "You came to teach in this library?" There was Li Chunfeng and you before. ”

"Actually, the juniors are not here to teach." Yan Liben whispered, "Your Majesty asked the junior to come and discuss the matter of the new firearm with Gu Qing. ”

"I see." Kong Yingda knew it in her heart, and she already understood what Gu Qing meant, "This study house is doing very well, you might as well take a look at it." ”

"Yes!" Yan Liben bowed and said, it was just hearsay that Kong Yingda came to teach in the study house before, but he didn't expect it to be true and saw the poems next to the study house, and couldn't help but read, "Hide in the small building and become a unity, and take care of his spring, summer, autumn and winter." ”

Thinking in his heart, Yan Liben said, "This sentence is a bit light, and the wording is very good, but it is always inappropriate to hang it in a place like the study." ”

"I like it!" Gu Qingman doesn't care, the study house was established by me, the study house was built with my money, and it is also the teacher I dug up single-handedly!

"That's fine." Yan Liben waved his sleeves, "Gu Qing, your reputation The old man has heard of it more than once, when he became Fang Xuanling's student, he knew you, he was talented but became a military general, he was resourceful but lazy to do, and his medical skills never opened a doctor, a good young man is a dead money, you have bad skills and bad skills, what is said in the market is right, you are a strange person, a strange person." ”

"Actually, it's quite tangled in the bottom." Gu Qing nodded and said, "Why do some people say good things and belittle me on the other hand!" Man, what a contradictory creature. ”

"On the day His Royal Highness King Wei married his little girl, the old man also saw you." Yan Liben turned around and said, "I just glanced at it in a hurry that day, but today I really don't have a long eye when I see the true face, how can such a good ability fall on a person like you." ”

“……”

I really want to beat him up, why do so many people say this, Yang Sheng? Where did it go? I'm going to beat someone!

Yan Liben looked at the strange desks in the study room and said, "You have pushed back and forth the matter of the new firearms, and you have painstakingly taken the old man around this time, but you want the old man to come to your study to teach these children to be craftsmen?" ”

"Don't hide it from Young Eunuch Yan." Gu Qing saluted and said, "I really want Young Eunuch Yan to come to the study house to teach first. ”

"You are a friend of King Wei, the little girl married King Wei, if you want the old man to teach the children, why bother." Yan Liben said bitterly, "You can say it bluntly, you opened the study house for the benefit of the Tang Dynasty students, just for the little girl, because His Royal Highness the King of Wei agreed to it." ”

"That's a promise?" Gu Qing was surprised, what about the festival? What about the wind bones?

"But the old man has a rule!" Yan Liben continued, "The skills of our Yan family have always been passed down to the descendants, and the old man can teach the children the most basic, but after that, the old man will not teach too much. ”

As long as people are willing to come, things can be slowly grinded in the future, if you don't believe it, you can't dig out the skills of this giant, as the old saying goes: it's better to be happy alone than to be happy, thinking in his heart, Gu Qing nodded hurriedly, "That's good." ”

The wind was biting in winter, and Yan Liben said, "Now we can talk about the new firearms." ”

"Yes." Gu Qing and Yan Liben came to the house, closed the door, and there were only two people left in a room.

Gu Qing said, "The explosives are detonated by the burning of the fire line, and this new firearm does not need the fire line but triggers the detonation." ”

"What's the reason?" Yan Liben was puzzled.

Gu Qing said again, "This new firearm has a name called landmine, and the difficulty lies in its triggering, because if there is no fire to detonate, its triggering is the core. ”

"Your Majesty has explained that the county can't say too much to the old man." Yan Liben said, "If the county tells the old man the complete method of mine manufacturing, the old man is afraid that it will be ......."

"I'm afraid it's a head move?"

"Hmm!" Yan Liben nodded awkwardly, "The county only needs to tell the county what is the opportunity to lay this mine, and those who can say that they can't say that the county can handle it themselves." ”

Gu Qing thought in his heart, if he told him the complete method of making mines, wouldn't this guy be dead? It's just killing people without seeing blood, forget it, I don't have any grudges against Yan Liben, besides, this guy has to agree to come to the study to teach, thinking in his heart and saying, "In fact, the method of making it is difficult to say, and it is not simple to say that it is simple, and the materials are stone, pottery, and iron." ”

Gu Qing drew out the shell structure of the mine with charcoal and handed it to Yan Liben, "This is the specific structure, but it has to be hollow." ”

Yan Liben frowned and looked at the drawings for a long time before he said, "The old man understands and takes his leave." ”

"Don't send it!" Gu Qing gave him his hand, "Young Eunuch Yan, remember to come and teach when you have time!" Closed at the end of the month in the middle of every month! ”

The design of the mine is a very simple iron box mine, the earliest use of this mine was in the Ming Dynasty, this kind of mine is also the earliest prototype of the mine, including stepping hair, tripping hair, pulling hair, point hair, low cost, although the lethality is not large, but it is enough to deal with those war horses on the grassland.

Those infantry mines in later generations, anti-tank mines Gu Qing can't do it, this kind of simple iron box is actually not difficult, and the watermelon-sized mines are also very bulky, in fact, they can be optimized, but Gu Qing doesn't want to do it, because he's lazy.

A few days after the landmine matter was settled, Li Er thought that as long as Yan Liben made the machine, he would let Gu Qing make a complete mine, but after hearing that Yan Liben went to teach in the study, the corners of his eyes twitched!

How many people does this Gu Qing want to go to the study house to teach, and letting Yan Liben go to see Gu Qing is simply a sheep's mouth, Li Er gritted his teeth, "Careless!" ”

"Kong Yingda, who has a literary Tao, was poached, and Li Chunfeng, who is famous, was also poached, and even Yan Liben was not spared!" Li Er was upset, "How many more people does this Gu Qing want, I will give them to him!" The minister of the court, he can't dig anymore! ”

Wang Qin also smiled bitterly, whether it was Kong Yingda or Li Chunfeng, they did not resign from their positions in the court but had to go to the study house to teach, Your Majesty was just angry, this Gu Qing's sharp-eyed boy dug up a few people, which made His Majesty anxious, but His Majesty spent a lot of effort to stay in the court, and gave a lot of official positions.

But this Gu Qing said a few words, and he poached people after a few tricks.
