When Tian Fan arrived at the craftsman camp, Zhou Ting saluted respectfully, made a fist with one hand, knelt on one knee, and sang: "Zhou Ting, the captain of the craftsman, see the military division!" Tian Fan hurriedly helped him up and said politely: "Brother Zhou is very polite!" Please! Tian Fan heard Liu Bei say this Zhou Ting, so he also gave Zhou Ting enough respect.

Zhou Ting hurriedly said: "Strategist, I'm a rough man, I don't deserve to be called that!" Tian Fan smiled and said, "Why did Brother Zhou say this? You're older than me, why can't I call you big brother in private? Zhou Ting is also an open person, smiled when he heard this, and said: "Since the military advisor said so, then Zhou Ting is better to be respectful than to obey his fate!" In the future, we will be commensurate with brothers in private, and according to our positions in official affairs. Tian Fan nodded and said, "That's right!" Zhou Ting nodded when he heard this, and said to Tian Fan: "Brother Tian, please!" Tian Fan was not polite to him, and walked into the craftsman camp first.

Zhou Ting's hut is located at the exit of the craftsman camp, facing the gate of the craftsman camp. A few people didn't enter the house, Tian Fan said: "Brother Zhou, let's go see the craftsmen first!" Zhou Ting nodded and led the way first. Tian Fan followed Zhou Ting and watched while listening to his introduction. He found that the management of the craftsman camp was well organized, various craftsmen were classified and had different territories, and the working area and living area were clearly divided, so he couldn't help but nod secretly! Zhou Ting's ability is really good, in just one month, the management of the craftsman camp is very neat!

They first walked to the carpenter's area, which was mainly responsible for the manufacture of siege equipment and various heavy vehicles, and by the way, they also made guns and the like, there were about 800 people, led by an old man of about fifty years old, named Zhao Shan! The old man was born in the mountains, so he got this name. Gray hair and beard, clothes are a little sloppy, thin and small, but when he speaks, he is full of energy! No, he's shouting! "Zhang Shiyi, you little bastard! What do you think you're doing? Did you do that? The shafts of the spears are all curved, do you use such spears? The young man named Zhang Shiyi stood in front of Zhao Shan with a red face and was being trained, and he didn't dare to resist even a word!

Tian Fan smiled and said to Zhou Ting: "Brother Zhou, it seems that this old man has a big temper, hehe!" Zhou Ting nodded and said, "Yes, hehe, Old Man Zhao doesn't have a good temper, but his skills are really good!" Brother Tian is going to meet him? Tian Fan shook his head and said, "Wait, I'll go around first!" With that, the two men continued to wander around with a few of their men.

There are about 700 people in the blacksmith quarter, and they are also busy here, dozens of workers are building weapons, and the clanging of hammers can be heard from afar. They were responsible for providing the army with weapons, swords, guns, swords, halberds, axes, hooks, forks, etc. Tian Fan just looked outside and withdrew, he really couldn't stand such a loud noise!

Then there is the armor district, about six hundred people. The person in charge is called Zhang Xiang, who is in his forties. Tao Qianjun's equipment is still good, ordinary soldiers can have a leather armor, even to the captain and the military horse, can have a leather armor with heart goggles, and everyone above the captain is an iron armor. There are many iron mines in Xuzhou, so the armor is still very strong. It's also very busy here, Xuzhou is just preparing to expand the army, and they are rushing to make armor.

The rest is the bow and crossbow area, about nine hundred people, responsible for making bows and arrows. Work is also in full swing here. Tian Fan was more interested in the bow and crossbow, and under the leadership of Zhou Ting, he walked into the bow and crossbow area. The person in charge of the bow and crossbow area is called Liu Zheng, and he was recruited from among the victims this time. This man was in his sixties, tall, with a straight waist, and a snow-white hair and beard, but his face was full of red! Seeing Tian Fan and Zhou Ting coming in, he hurriedly greeted him, casually saluted Zhou Ting, and asked, "Captain Zhou, why are you free to come over today?" Zhou Ting pointed at him and laughed: "Okay, old man Liu, don't you owe me a drink?" As for being so afraid of me? Hehe, this is Tian Junshi, I'll accompany him to take a look! ”…,

Liu Zheng listened, looked at Tian Fan carefully, and asked respectfully, "But Mr. Tian Boguang is in front?" Tian Fan hurriedly replied: "In front of the elders, I don't dare to call Mr." It's Tian Fan! After hearing this, Liu Zheng straightened his clothes, made a big salute again, and said loudly: "I've seen Mr. Tian!" Tian Fan hurriedly pulled him up and said in a loud voice: "Old man, don't do this!" Anyone who is young can't afford the old gentleman's gift! Liu Zhengzheng said: "Mr. Tian saved my whole family, but you can stand this gift!" Zhou Ting also said: "Brother Tian, Lao Liu is such a person, no one can change the things he recognizes, you should still accept his courtesy, otherwise you won't be able to do anything today!" Tian Fan was helpless, so he had to let him salute.

After the ceremony, Tian Fan said: "Mr. Liu......" Liu Zheng hurriedly stopped and said: "Strategist, don't call me sir, I really can't afford it!" Tian Fan nodded and said, "Okay, I'll call you Lao Liu, and you call me Boguang, how about it?" Liu Zheng thought about it and agreed!

Liu Zheng took Zhou Tingtian Fan to visit the bow and crossbow workshop, and explained while turning. “…… The material of the bow arm is best made of chestnut wood, which is strong and tough. As for whether the arrow is accurate or not, it depends on whether the wood grain is straight or not......" He picked up a finished bow, pointed to the bow arm and said: "Just like this bow, the wood grain is delicate, straight to heaven and earth, and the gap between the wood grain is uniform and equal, so that the ejection force can be even, and the arrows released can be impartial." If the texture of the wood is uneven, it must be corrected when shooting arrows, otherwise deviations are likely to occur! Tian Fan nodded and said, "Can you make all bows the same?" Liu Zheng said with some embarrassment: "It's difficult! There are many influencing factors such as different craftsmen, different levels of craftsmanship, different ages and origins of wood, etc.! Tian Fan nodded thoughtfully.

What Tian Fan didn't expect the most was that Liu Zheng could actually make crossbows! It's not a strong crossbow, it's not a stretch crossbow, it's a repeating crossbow! This repeater is not a semi-automatic weapon repeater that Zhuge Liang improved, but the kind that emits multiple crossbow arrows at once. There are three kinds of crossbows in the Han Dynasty, one is one with one arrow and three arrows, which can be operated by one person; the second is one arrow and more than ten arrows, operated by two people; The most perverted one, operated by three people, shaped like a car, a hundred arrows at a time, but it takes a long time to prepare, so in war, this thing is just a one-time consumable! During the period of Emperor Wu, when the two generals of Wei Huo went on an expedition against the Xiongnu, these three kinds of crossbows played an extremely important role! On the grassland, the Hun cavalry galloped on horseback, and suddenly, like locust arrows sent over as if they didn't need money, who could hold on? Li Ling led 5,000 inpacles, and the reason why he was able to withstand the siege of nearly 100,000 cavalry of the Xiongnu and kill and wound more than 10,000 people was precisely because he was equipped with these kinds of crossbows! It was not until the crossbow arrows ran out, and in the realm of no reinforcements outside and no grain and grass inside, that Li Ling was defeated and surrendered.

It's a pity that after Emperor Wu, most of these superb crafts were lost! Liu Zhengzu made bows and crossbows for Emperor Wu, although the emperors after Emperor Wu no longer paid attention to the manufacture of these weapons, but his family's craftsmanship has been handed down! It's just that he can only make the first two, the third type of crossbow, and he can't do anything! After Tian Fan heard about it, he immediately decided to let Liu Zheng get these kinds of crossbows out, first see the effect, and if the effect is good, then mass produce and equip the troops.

In Zhou Ting's hut, Zhou Ting, Zhao Shan, Liu Zheng, Zhang Xiang, and Zhang Sheng, the head of the blacksmith, were sitting separately, listening to Tian Fan. Zhang Sheng is about forty years old and has a very inconspicuous appearance.

"Just now, I went around the area you are responsible for, and I am very happy to see that everyone is very diligent!" Several people couldn't help but smile when they heard him say this.

"However, hard work and diligence alone are not enough, and I find that the efficiency of everyone's work is very problematic!" Zhao Shan was straight-tempered, and when he heard this, he asked, "Strategist, why is our efficiency a problem?" We've been working hard! Tian Fan said: "I know you are all working hard, I didn't say you are lazy!" I'm just saying that there could be some improvement in your working methods! Seeing that the four of them were about to speak, Tian Fan waved his hand and said, "Listen to me!" Lao Liu, listening to you just now, I feel that there are some things that need to be discussed with you! You said that it is difficult to guarantee the same with the bows you produce, and this situation is likely to affect the use of soldiers. I've thought of a solution, and I'll talk to you about ......"...,

Tian Fan listened to what Liu Zheng said, and suddenly thought that if the influence of materials is eliminated through unified selective procurement, and then standardized assembly line production methods are used to eliminate the gap in craftsmanship between craftsmen, it should be possible to make the bows produced the same! Again, this method is suitable for other positions in the artisan camp. In fact, the production method of the assembly line has been used in the Qin Dynasty, but it was lost later, which is not Tian Fan's initiative!

After listening to Tian Fan talk about the method of standardized assembly line operation, the four craftsman leaders were stunned! These four are all old craftsmen, and it is impossible for them not to understand the benefits of this method! Everyone is only responsible for a small part of the work, just a small step, no matter how stupid people will become experts after a long time! This method will definitely improve your work efficiency!

After the excitement of the four people passed, Tian Fan took out two drawings, one was a Quyuan pear and the other was a trebuchet. It's a pity that it's all concept drawings, and he's not a professional, so he can only draw rough concept drawings.

"This is Quyuan pear, it has three benefits, one is labor-saving, only one cow can plough the land, the second is easy to turn, easy to use when ploughing, and the third is to adjust the depth of the plough into the soil, suitable for all crop cultivation. This is a trebuchet, its function is to throw stones, when attacking or defending, it is very useful! You guys study it carefully, the drawings I drew are not very accurate, let's improve it together! After speaking, Tian Fan told the four of them about the characteristics of the two things, and it was not until dusk that Tian Fan left. Tian Fan believes in them, as long as they are given some time, these two things will definitely come out!

In addition, every few days, he went to the barracks to see the training and chat with Zhang Fei and Cao Bao. After contacting Cao Bao a few times, he found that Cao Bao was not a bad person, but he couldn't see the situation clearly, and he couldn't bear to watch Cao Bao and Liu Bei go against him and be killed. He is trying to persuade Cao Bao to completely join Liu Bei's camp and worship Liu Bei as his lord. First, it was to prevent Cao Bao from being killed, and second, Liu Bei could receive the more than 20,000 troops peacefully.

As for Chen Deng and Chen Qi, this kind of person is too smart to persuade him with his own IQ. Besides, if Liu Bei develops well, they will naturally assist Liu Bei with their hearts, where can they use themselves to persuade them?

Liu Bei took matters into his own hands and also invited back a capable person, Sun Qian and Sun Gongyou. It was recommended by Zheng Xuan to Liu Bei when Liu Bei visited the celebrity Zheng Xuan before. Tian Fan has met Sun Qian a few times, and they can talk about it relatively well. He took the initiative to ask to resign from the position of military advisor and give it to Sun Gan, Liu Bei is not good at saying anything, one is a talent who has just been invited, and the other is also a talent (he thinks so about Tian Fan), but Sun Gan is unwilling, how can he grab someone's position when he just came?

Tian Fan was very depressed, and said to Liu Bei and Sun Gan: "Lord, Mr. Gongyou, I know my own ability, and occasionally I can come up with a good idea, but you let me think of ideas every day, I have to go crazy!" This position of military advisor is still taken by Mr. Gongyou! I'll just take up an idle position, and if there's something I can do myself, I'll take it, wouldn't that be good? Mr. Gongyou's talent is 100 times better than mine, please don't shirk! Liu Bei saw that Tian Fan was indeed sincere in resigning from the position of military advisor, so he agreed.

Sun Gan's heart was moved, what a good person, he just gave up such a high position to himself, what a good person! Liu Bei was also very moved in his heart, seeing how good Boguang is, he took the initiative to give way and was not greedy for power, he was really a good person! Tian Fan was also very happy in his heart, hey, how tiring is it to be a military advisor? Let's live my free life! Everybody's happy......
