The person at the top is quite young, but in his thirties, with a mustache, a heroic appearance, and a hint of arrogance on his face, which can be known to be the son of a famous family. One of them is only about thirty years old, with a long beard, and he looks quite like a person, and his face is not wavering, and he can't see any likes and dislikes.

Yang Yu got up to greet Guo Yi, first saluted, and then respectfully reported, first pointing to the man with a mustache, "Husband, this is Mr. Cai Mao." "Referring to the bearded man again," this is Mr. Huang Chengyan, and they have been waiting here for an hour and a half. ”

Cai Mao and Huang Chengyan also stood up and greeted Guo Yi, which was regarded as a greeting. While Guo Yi asked them to sit down, he instructed Yang Yu to serve wine and food, and asked Zou to play a song about the mountains and flowing water.

"The two gentlemen came, and the humble house was full of light. I wonder what the two gentlemen have to say? ”

Cai Mao asked with a smile: "I have heard the general's prestige for a long time, and I can see it today, which is really comforting to talk about my life." The two of us came uninvited to offer advice to the general. ”

"Oh?" Guo Yi looked at the two of them with interest, Cai Mao needless to say, a typical scholar surrender faction, relying on their nepotism with Liu Biao and the influence of the Cai family in Jingzhou, directly surrendered Jingzhou to Cao Cao during his southern expedition, and finally ended up in the extinction of the life and death clan.

Huang Chengyan is not famous and has great achievements, but he has an ugly girl, and the ugly whole Jingzhou is famous, but this ugly girl is married to Zhuge Liang. With the name of his son-in-law and the allusion of "marrying an ugly girl", he can be regarded as leaving a little trace in history.

"The two gentlemen just have to say, and the juniors will listen to them."

Cai Mao glanced at Huang Chengyan and said with a smile: "The general is a person from the north, and now he has come to the land of Jingxiang as an official, if he does not practice water warfare, I am afraid that it will be difficult to suppress bandits and calm the people." I came to train sailors for the general. ”

"Oh! Welcome! Guo Yi hurriedly got up and left the table, ran all the way to Cai Mao, grabbed his hand tightly, and said excitedly: "I am suffering from lack of water, and the soldiers have many complaints. The two gentlemen are really timely rain! The two of you just have to say what you want, and you will fully cooperate with you. ”

Cai Mao smiled and said, "Don't worry, general, we will do our best." After the deed is completed, it is not too late for the general to ask for compensation. ”

"Good! Good! Guo Yi cheered again and again, and hurriedly asked people to bring the wine and food and drink with them.

After drinking three or two cups, Huang Chengyan finally spoke. "General Suwen is known as 'Luban', and he must be clever. A carpenter's craftsmanship is also good, and there are a few drawings to be tasted by adults. ”

"Sir is gracious." Guo Yi took the drawings and was stunned, this is a set of design drawings for bows and crossbows, but it is obviously only a draft, and there are many incompleteness.

Although Guo Yi is an industrial design student, he knows the drawings of various industrial products well. But they are all products of the industrial revolution, such as: steam engine, internal combustion engine. Or a cold weapon with a simple structure, such as a sword, gun, sword and halberd. For bows and crossbows, he only knows the design of modern compound bows, the design of crossbows and arrows at a time.

This set of drawings is obviously a pursuit of a bow and crossbow that can be fired in bursts, but the designer seems to be struggling with how to make the bowstring automatically fill and reload the arrows after firing.

"Zhuge Repeater!" Guo Yi suddenly remembered, didn't Zhuge Liang come up with such a set of things in history? To a certain extent, the Zhuge repeater crossbow has made up for the shortcomings of the infantry's combat effectiveness and greatly improved the combat capability of individual soldiers.

"Could it be that this is Huang Yueying's handwriting?" It is said that when Zhuge Liang was designing various weapons, Huang Yueying was very helpful. However, as far as Zhuge Liang in history is concerned, he does not look like a person who is proficient in industrial technology. Then things such as "Wooden Ox Flowing Horse" and "Zhuge Repeater" are likely to be Huang Yueying's works.

"Give me the pen." Guo Yi beckoned, and Yang Yu immediately handed over a hard pen. Guo Yi's calligraphy is very good, with the thin gold body copied from the modern period, it is unique in the late Han Dynasty and has become famous. But when drawing drawings, he always uses a hard pen, which is purely a "professional habit".

Guo Yi revised it on the draft drawing, although there is no research in this area, but he is from a professional class, how to make a product reasonably designed, produced, and used, is what he is best at.

It took about half an hour, Guo Yi put down the pen and returned the drawings to Huang Chengyan.

Huang Chengyan was stunned for a moment, his eyes were full of confusion, as if he hadn't figured out why he designed it like this. Guo Yi didn't care, Huang Chengyan was a celebrity and a Confucian scholar, and he must not be ashamed of these "last arts".

"Please go back and tell Ling Yan that if you have any questions, you can write to ask, and I will answer everything."

"Ahh Huang Chengyan was greatly surprised, looked at Guo Yi in disbelief, and said in a lost voice: "How did the general know about the little girl?" ”

Guo Yi smiled slightly, "It's just a rumor." ”
