Wang Mubi, Erin, Xiao Ke, and Zhang Mazi moved a stool and sat in front of the desk, and began to continue the previous conversation.

After experiencing the verbal bombardment of Wang Mubi, Zhang Mazi looked at the drawings on the case with a serious look, although he couldn't read the words, but there was no obstacle to reading the pictures.

"Okay, Xiaoke, let's talk about it, what do these words represent?" Wang Mubi pointed to the words on the drawing, and the school was examined.

"Isn't it just a crossbow, there is one in the royal city, I knew it in the book at the beginning, but it's a little different from yours. Also, I said that I don't like people to call me Xiaoke. Collistol emphasized.

"Yes, it turns out that you have a crossbow here, so tell me, what is the difference between it and mine?" Wang Mubi touched his chin, and it was not surprising that he would develop a crossbow after playing with the bow to a certain extent.

"There is no specific crossbow in the books, only an appearance. Collistol was frustrated, but it was not a difficult thing to understand, how could a nobleman who had a monopoly on knowledge dare to teach others such a lethal weapon.

"You can also talk about the appearance. "It doesn't matter if Wang Mubi writes, do you know how to do the crossbow machine, it's not by playing civilization in the past, playing games like empire, plus some modern concepts of single crossbows, you can draw it casually, otherwise, you don't need to take it out and discuss it.

"Well, in terms of appearance, the arm span feels bigger than what adults draw, and then the base is not as big as adults, let alone wheels, and then this pulley group doesn't know what to do, chute... I don't know what this is for, and there is a problem with the angle of the adult, shouldn't the crossbow machine be a flat shot?"

Wang Mubi sorted out the language and said slowly,

"Well, first of all, the issue of the reach and bowstring. Zhang Mazi, let me ask you, a formed bow, let's not talk about a crossbow, let's talk about a bow, a formed bow, how long does it take to get a bow arm?"

"This... It's been a long time, and I still know how to make a bow, but there aren't many people in the town who use it, after all, the bow has very, very high requirements for eyesight, physical strength, and talent, and it should only be slightly cheaper than training a knight. The bow is divided into a longbow and a short bow, the longbow is powerful and has a long range, but we don't know how to do it, the short bow is the kind I made for Milley, so it can only be used in the mountains, shooting those animals at close range, so I guess the short bow should have relatively low requirements for the bow arm. Zhang Mazi probably said so many words for the first time, biting his tongue a few times in the middle, and pausing for a while before continuing to speak,

"Although the short bow is simple, but to do well, at least the bow arm should be made of yew trees after drying, bending, soaking in oil, and then repeating, etc., the last short bow, if you want to use it, it will take at least one to two years, like the bow I made for Milai, even used for three years, and the material was also selected from the Tuomu tree instead of the purple shirt tree. ”

"Wait, Tuomu Tree, is it a tree with thorns?" Wang Mubi stopped when he heard this.

In fact, Wang Mubi doesn't know any trees or anything like that, but Wang Mubi, who likes to play farming games like the Civilization Empire, naturally can't miss a game called Three Kingdoms, but if you think about it carefully, it's not just the Three Kingdoms, it seems that all the games that Wang Mubi has played with the Three Kingdoms will have a bow system god Li Guang bow, and it is clear that Li Guang and the Three Kingdoms can't touch the edge. Having said that, what Li Guang used is the rhubarb crossbow, and because there has been no prototype unearthed, there are many theories around the material of the rhubarb crossbow, the more common is Tuomu, Tuomu is known as the golden tree, the heart is golden, and the material of the bow arm is also the best Tuomu, so Wang Mubi heard Zhang Mazi's words, so he asked.

"Yes, there are indeed thorns, is there anything wrong with you?" Zhang Mazi replied.

"No, what you said is very good, the short bow is still like this, what about the longbow, the crossbow machine that is stronger than the longbow? Won't it take two to three years to take shape? Then let's look at the current situation, do we have time to wait until two to three years later?" Wang Mubi stopped asking about Tuomu, and continued to talk about the bow and crossbow.

"No, we're running out of time, it's snow season soon. Collistor replied.

"Yes, so Xiaoke, all your considerations are meaningless, the bow arm does not need to be too long, because the longer the higher the requirements for wood, the bowstring does not need to be durable, because our purpose is to spend this snow season, the wheels are to facilitate transportation and movement, as for the angle problem, it is also because, what we want to use, is another way to use the crossbow machine, as for the chute and pulley group, it is labor-saving, how to operate, now I will not say, when the time comes, you will probably make the crossbow machine, I will talk about the chute and pulley group things, of course, you have to remember the confidentiality, the highest level of secrecy, can only say to Lin Sensen and Qian Duoduo, understandWang Mubi carefully advised, Collistol and Zhang Mazi both nodded solemnly, but Wang Mubi also underestimated his current influence, and now the people in the whole town know that Qian Duoduo is respectful in front of the divine envoy, not to mention them, leaking such a thing, that is absolutely not daring to do.

"Well, okay, then let's move on to another thing, this thing, you don't need to build it, just make a simple device, and then we'll go to the Dark Fortress to get local materials. Wang Mubi turned to another pattern on the drawing, compared to the crossbow machine, this is too simple, there is only one chassis, a strut, and a bracket.

"It's called a stone thrower, don't look at me, I'm just drawing it, but in fact its principle is already very clear, of course, it's also very troublesome to explain the lever to you, Erin, bring a plank. ”

Erin took a wooden board according to the instructions of Wang Mubi, Wang Mubi picked up the wooden board, felt it, found a relatively round piece of wood, aimed at the direction of the no-man's land, and put the plank on it, one side long and the other short, and then, Wang Mubi took a small piece of wood casually and put it on the long one.

"Okay, Erin, you go jump, no, forget it, Zhang Mazi, you come here, jump on that short plank, pay attention to safety. Wang Mubi was reluctant to take risks with his maid, and called Zhang Mazi to do the experiment, only to see Zhang Mazi jump, the long end of the plank bounced up, with a small piece of wood, flew directly into the no-man's land, and couldn't find a shadow.

"Well, that's it. Wang Mubi said.

"What's the use of this, is this?" Colistol wondered.

"No, you kids haven't played with seesaws?" Wang Mubi asked rhetorically.

"No, we all have to help with the housework, so how can we have time to play. Collistol said with a little sadness. Said.

"I think it's because others don't take you to play, it doesn't matter, it's not much cooler to follow my brother to do the right thing, it's not much better than playing with those little kids. Wang Mubi noticed the change in Collistol's mood and thought that he was intimate and comforted.

"......" Collistol seems to be in a worse mood.

“...... Master, you don't have to say anything. Erin reminded with a wry smile.
