There are no catapult patterns, but a lot of parts are steeled, the same handmade springs and pulleys!

The most important thing is that the catapult has changed the use of wooden arms to rope belts! The stone bullet was attached to the rope belt. This way of driving away wolves from herders has greatly increased the distance of catapults!

In the past, giant catapults generally had an effective lethality of between 200 and 260 meters; Small catapults are closer; With the improvement of ropes, the distance has increased greatly, and the current giant catapult has increased to 400 meters, which is Zou Yu's confidence in attacking Goguryeo.

Siege is always the next policy, but it has to be fought, Goguryeo has many cities, are built in the middle of the mountain, or belong to the slope is relatively large, which undoubtedly increases the difficulty, which is why Emperor Wen of Sui and Yang Guang father and son, many times attacked and could not be defeated.

"I don't know what the value of this batch of weapons is?" Zhong Zijin asked cautiously. If it's the same price as a steel knife, I'm afraid he'll have to worry about how much he can afford it.

"Don't worry about this, you are all acquaintances, and when you are in a difficult time, this king will definitely not sell at a high price!" Zou Yu said loudly.

"Thank you so much! I don't know how much a handle! Zhong Zijin breathed a sigh of relief and asked with a smile.

"So be it! I don't bargain either! 100 catties of wheat for a handful. Zou Yu thought for a while and said.

"Can the prince do without food? Because we have given up part of the land, we don't have much food now. Zhong Zijin said with a wry smile. If you want to talk about the price, it is indeed not expensive, but now they are also very short of strategic materials!

"It doesn't matter! What do you have? As long as it's valuable, it's fine! Zou Yu said magnanimously.

"This..."Zhong Zijin frowned, thinking about it, he was thinking about what else was worth it, but he was not in a hurry to use it at the moment.

"The head of the Zhong family doesn't want to take it for nothing, right?" Zou Yu's face sank and he said unhappily.

"Nope! No! How could it be, I'm just thinking about what to exchange for, it's more appropriate! Zhong Zijin hurriedly waved his hand and said.

All he brought with him were some ordinary cloth and gold, silver, and bronze, as well as some pearls and precious stones. You must know that in the past year or so, there have been a lot of things to change in Shicheng, and some of the liquid wealth of several major families is not much, and now it is necessary to change a large number of weapons, which must be too bad.

"Oh! I don't care, for the sake of friends! Anything of value can be used. Zou Yu leaned back in his chair and said in a long voice.

"It's... Lord, why don't we exchange another city? What is your estimate? Zhong Zijin asked cautiously with a sad face.

"Don't! No! What am I going to do? You have to put a lot of effort into governance! The Central Plains can't be busy, where is the air traffic control here.

And your people, they all think that they are Goguryeo, change the country, what do you make them think! It's so hard to manage! The people below have complained to me many times! Zou Yu immediately refused loudly.

Firm tone! The disgusted eyes all showed that Zou Yu really didn't want it, which made Zhong Zijin even more headache, where to get so much money out of the city and land.

Of course Zou Yu didn't want it, those cities, he had long regarded them as his own, how could he let others exchange their own things, this would not be a loss-making business.

"Ahem! If the head of the Zhong family can't come up with so much money for a while, it's okay, I have a way. Zou Yu coughed dryly twice, and said to Zhong Zijin, who was stunned.

"Please also ask the prince to show the way!" Zhong Zijin looked up and asked in surprise as if he had been in a drought for a long time.

"Population! I need a lot of people to farm! In the past few years, you have been constantly fighting, and there are not many people in these counties and counties in Liaodong at all! The land is in ruins! So I need a lot of people. Zou Yu said dissatisfiedly.

Such shameless words made Zhong Zijin speechless, as if this war had nothing to do with him! In the past few years, it has not been him who has made the most trouble.

"You still kill so many people if you lack people!" Zhong Zijin muttered to himself, and then said helplessly: "Lord Wang, we are also short of this population!" Without population, there is no way to recruit soldiers, and there is no source of soldiers, how can you resist Gao Jianwu! ”

"I don't care about this, either take the money or take the people! I can't give it to you for nothing, can I? Young and strong one for three handles! The same is true for women; The old and the weak and the children, three for one! I'm worthy of you, right? It's equivalent to the whole family, and you can send them all over.

Didn't you say that you would exchange the city for it? I don't want the city, as long as the people inside, it's not good? Maybe you're trying to trade for an empty city, right? Zou Yu said dissatisfiedly, and in the end, he looked at Zhong Zijin with suspicion.

Zou Yu was furious when he saw it, after all, he was in the camp when he was killed, and he still remembers that scene clearly, every time he sees Zou Yu, he is a little weak-hearted, worried that if he is not careful, he will be dragged out and killed.

"Nope! No! No. I can't do this alone, I need to go back and discuss! Zhong Zijin hurriedly replied.

"Haha! No hurry! No hurry! Anyway, the weapon is here, when will you send someone, when will you take the weapon and leave!

And dried fish, a lot of dried fish! Zou Yu asked with a smile.

"Dried fish?"

"Yes, dried fish! In this way, I'll show you the goods first, and after reading it, you can decide! Zou Yu nodded and said, after speaking, he asked someone to send the knife, and ordered to make a few dishes with dried fish and send them over.

This batch of knives is relatively thin, and the sharpness is very good, and for the bark armor of trees, it is easy to break. Of course, this was what Zou Yu deliberately tried to show him, because the characteristic of this batch of knives is that they can't cut things that are too hard, even if it is bluestone, it may collapse. If it's chopped multiple times, that's for sure.

Thinking that the Goguryeo people used it for a while, and the weapon turned into a sawtooth, Zou Yu felt a little funny in his heart.

It didn't take long for a dish of dried fish boiled with vegetables, a dish of fish porridge, a dish of steamed dried fish, and a dish of fried dried fish to be delivered.

"How about a taste?" Zou Yu gestured.

"Good! You're welcome! Zhong Zijin arched his hand and then began to taste.

"Lord Wang, this should be a fish in the sea, right? It's really good, not only delicious, but also salty! It's just that as a military ration, some of it is wasted! Zhong Zijin looked at it carefully, tasted it carefully, and said.

For Zhong Zijin to say that it was a waste, Zou Yu couldn't help but twitch the corners of his mouth, he didn't have anything to do with the soldiers at all. However, Zou Yu didn't want to discuss this issue with him, so he just nodded and introduced: "Not bad! It is indeed fish in the sea, although it is more expensive than grain, but it can be used as salt to make the meal taste better; And if you eat better, the soldiers will definitely be better in terms of momentum and body! ”

Zhong Zijin thought for a while and said: "I can buy some of this dried fish and let the elite soldiers eat it, as for the ordinary soldiers, forget it, I can't afford it." ”

Zou Yu didn't care if Zhong Zijin really couldn't afford it, or he didn't want to increase this expense, anyway, it would be good if he could sell some of it. He mainly produced a large output, and because Beisha Stone City was not far away, it was more cost-effective to sell, otherwise he would be reluctant to give it to Zhong Zijin.

After negotiating, Zhong Zijin immediately set off to return, whether it was a transaction or not, this needed to be discussed back.

"Let's find out, how many people did Zou Changfeng bring to Stone City? And where did it come from? Has there been a large number of people coming in and out of Liaodong recently? Zhong Zijin instructed his henchmen.

"Whoa!"
