"Qin Tian, what are you doing with so many weapons and crossbow arrows to defend the city?" Huan'er couldn't help but ask curiously.

"Use it yourself, you still have to fight the battle! you can't prepare when it's time to fight, right?" Qin Tian said noncommittally.

"Nonsense, how can you use up so much by yourself, you are clearly a lie. "Pei'er is not a glass who doesn't understand anything, she pierced Qin Tian's lies in one bite.

Qin Tian smiled and didn't care, he glanced at Pei'er, and then continued: "Of course, if you can't use them up, you can also use them to exchange them for some food, riding beasts or something with others." After all, these are good things! Are you afraid that no one will want them?"

"Oh, so I used it to exchange for supplies!" Pell nodded, knowing how much it would take to maintain such a large territory. It is indeed difficult to sustain such a large consumption with local output alone.

As the head of the smelter and the master of the craftsman, he has been constantly improving the production processes of the two factories to improve the production efficiency of weapons.

The division of labor and step-by-step assembly-line work mode was calculated after he discussed with the fat man. This new model breaks the previous manual work mode of individuals and greatly improves the efficiency of production.

In particular, the theory of large-scale mechanical production put forward by the fat man Yan Qiu opened his eyes, and if this theory can really be realized, then the production efficiency of weapons will be greatly improved. As a master crafter, this kind of subversive theory was something he had never imagined, but he was fully able to understand its profound implications.

The so-called theory of large-scale mechanical production, simply put, is to use large machinery to help produce weapon parts and reduce the burden for subsequent work. The biggest difficulty in this theory is the problem of energy, how can the energy of Blackstone be converted into the power to drive the work of machinery?

This question has been worrying Tie Ye, and the fat man has not been able to say why, he only suggests trying it with the vapor formed by boiling water. However, Tie Ye tried many times but did not achieve any effect, and today it happened that Qin Tian came to inspect, so he took this issue out and discussed it with Qin Tian.

Liuli was still a child's heart, she only looked east and west, and didn't notice Qin Tian's conversation. And Huan'er, as the young lady's maid and guard, she has always paid attention to even any abnormality.

The topic discussed between Tieye and Qin Tian surprised her, this model that can improve production efficiency several times is another kind of innovation that breaks through the convention. If it can really succeed, it will have an immeasurable impact on the level of weapon development of the entire human race.

While carefully and silently recording the conversation between Qin Tian and Tie Ye, she was also constantly thinking about the answer to this question. But thinking about it, her little head began to ache faintly, and she couldn't figure it out.

Faced with the problem of iron smelting, Qin Tian knew that it was the ghost of the fat man Yan Qiu when he heard it. In such a primitive environment, if you want to realize mechanized mass production, it is simply a dream. Even if you figure out the principle of the steam engine, if you want to produce a really usable steam engine, it will not take more than ten or twenty years, and there is no possibility at all. When I really wait until then, I'm afraid the daylilies will be cold!

The fat guy Yan Qiu probably also thought of this problem, so he refused to tell the truth to Tieye. Alas, now that this hot potato has been thrown into his hands again, I really wonder if this fat guy is a professional pit teammate?

Qin Tian rubbed his aching head, pondered for a while, and then said to Tie Ye: "Uncle Tie, I don't think you should think about this steam engine. Even if you can figure it out, if you want to really make it workable, then I'm afraid I don't know if it's the Year of the Monkey. I think you might as well try to push it with water directly, we don't have much else to do with the cold spring, this cold spring is a lot. You find a spring on the mountainside, and you draw water down from the mountain, build a tower at the base of the mountain to store water, and try to use the momentum of the water in the tower to propel the machinery. If it succeeds, you can use it to push the hammer and forge all kinds of weapon parts, so that you can save a lot of effort, don't you say?"

"Ah, what a good idea! Why didn't I think of it? It can be propelled with water! We also have people here to use the water mill!" Tie Ye was overjoyed, this problem that plagued it was actually solved by Qin Tian so easily. The lord is really a lord! much more reliable than the fat man who has been avoiding him lately!

Just as Qin Tian and Tie Ye were discussing something hot, a soldier suddenly hurried over and handed Qin Tian a letterhead.

Qin Tian took the letterhead and opened it, and immediately frowned tightly, Tie Ye saw Qin Tian's expression so solemn, and hurriedly asked, "Lord, what's wrong?"

"See for yourself!" Qin Tian handed the letterhead to Tie Ye. Tie Ye took a closer look at it suspiciously, and saw a line of words written on the letterhead: "Cai's army gathered to fight with Yan's army in Heishi Village." ”

"Yan Clan?" Tie Ye's face was stunned, he lowered his head and pondered for a while, then he raised his head sharply and asked suspiciously, "Could it be that Yan Rong is from the Yan Clan?"

Qin Tian shook his head and said, "I don't know about this, there is too little information now, it seems that I have to go in person." ”

"Lord, this must not be done. As a lord, how can you take the risk yourself?" Tie Ye immediately objected.

"Needless to say, I've made up my mind. This matter is related to the safety of my Cold Spring Collar, and I must find out for myself. Inform Mr. Ram first and ask him to assemble his army. If necessary, we will also go to war. Qin Tian vetoed Tieye's persuasion, and he said with a firm face.

Seeing that Qin Tian was so resolute, Tie Ye knew that he couldn't persuade him, so he could only nod and say, "Since that's the case, I'll go and inform Ram Shen immediately." It's just that you must take care of yourself, lord!"

"Don't worry, I'll be fine. ”

After Qin Tian said that, he turned to the three of Liuli and said, "Let's play here today, the three of you go back to the room to rest first!"

"I want to go too!" said Pell with a look of longing.

"No! none of you are allowed to go!" Of course Qin Tian would not agree to take her with him, isn't this unpleasant for himself?

Qin Tian came out of the cold spring collar from the fortress and kept rushing towards the Black Stone Village in the direction of the avenue. He was worried about the battle between the Cai family and the Yan family, so he didn't entangle too much with the Cai family's spies on the road. Instead, he directly increased his speed to an extremely high level, and the whole person turned into a light wind, rushing towards the Black Stone Village without stopping.

The Cai clan has arranged a lot of spies outside the Cold Spring Territory, and they are responsible for monitoring the movements of the Cold Spring Territory, and by the way, intercepting some of the spies of the Cold Spring Territory. On this day, Cai Laosi and Cai Ya were lying in ambush on both sides of the road, preparing to intercept and kill the possible Hanquan Leader spies.

Just when they were bored, they suddenly saw a black dot moving in their direction at high speed in the distance.

Cai Ya immediately raised his head, he patted Cai Laosi's shoulder beside him and said, "Fourth uncle, there is a situation." Looks like a spy, should we give that guy an arrow?"

Before he finished speaking, Cai Laosi held his head down, and suddenly fell to the ground, and his mouth gnawed a mouthful of mud.

When Qin Tian passed by here, he coldly glanced at Cai Laosi and Cai Ya, who were trembling with their heads buried in the ground, and then continued to hurry as if nothing had happened. He didn't have much time to waste on these little minions.

When Qin Tian walked away, Cai Laosi slowly raised his head, and at this time, his whole body was soaked with sweat.

"Ahh ”

"You kid knows a fart!Is that a thief? That's obviously a god of death, okay? You idiot wants to die, don't catch up with your fourth uncle!" Cai Laosi suddenly scolded.

Cai Ya has been afraid of his clan uncle since he was a child, and when he saw Cai Laosi jumping in anger, he was immediately stunned.

Cai Laosi scolded for a while, and then he slightly expressed the fear in his heart, and he glanced at Cai Ya, who was like a quail, and said, "Look at your little bit of talent, where did you run away with all that courage just now?"

"Isn't this being scolded by you all the time?" Cai Ya replied in a low voice.

"Stupid! Lao Tzu just scolds you, you don't dare to speak out. That killing god just now can chop you up and feed you to the dog in a minute, but you have to go up and shout and shout to kill! Do you think you're stupid?"

"Uncle, how do you know that person can beat us?" Cai Ya finally understood something.

"Nonsense! You don't have long eyes yourself! You can't see his terrifying speed? Think about it first, can you draw a knife and get a hair on someone's body?" Cai Laosi said with a look of disdain.

Cai Ya instinctively wanted to refute, but after thinking about it seriously, he was also scared into a cold sweat. He trembled and asked Cai Laosi: "The fourth uncle, what should we do? That person just passed over, what if the boss blames him?"

"People, who people, why didn't I see anyone passing? Cai Ya, did you see it?" Cai Laosi asked with a puzzled expression.

"Uh!" Cai Ya opened her mouth wide and looked at Cai Laosi with a puzzled expression. He never thought that someone's face could change so quickly, and he could tell nonsense with his eyes open, and he could say it as if it were the real thing.

"Cai Ya, what about the person you are talking about? Why didn't I see it?" Cai Laosi looked like he was killed and didn't recognize it.

Cai Ya was stunned for a while before he came back to his senses, and he blushed a little and said, "Uncle, I didn't see anyone passing over." Maybe the wind and sand were so big that I was dazzled, and no one went there at all. ”

"Oh, it turned out to be dazzling. It's good that no one has passed, so let's continue to ambush!" Cai Laosi nodded with satisfaction and said.

"Okay, uncle!" Cai Ya's words became more and more slippery, it seems that it won't be long before an old fritter of the Cai Lao Si style can grow up and continue to make greater contributions to the Cai family!
