Although Xu Huang had some light enemies, his weapons were all knocked out by Liu Zheng, and it could be said that Liu Zheng had won.

If there is no weapon in the war, Liu Zheng's blow is likely to kill Xu Huang.

After knocking Xu Huang's weapon away with one blow, Liu Zheng was overjoyed in his heart, and he was also extremely happy.

"Hahaha, Brother Xu Huang, how is it, do you think I've become stronger."

"What's going on?"

Xu Huang was a little surprised, but he didn't feel ashamed that Liu Zheng had defeated him.

On the contrary, those onlookers saw that Liu Zheng had actually defeated Xu Huang, and immediately burst into fierce cheers.

In their opinion, Xu Huang's strength is a high mountain, which no one can surpass, but Liu Zheng was able to defeat Xu Huang like this in front of them, although it was only to fly Xu Huang's weapon, it was enough to prove that Liu Zheng's strength was also good.

One by one, there was a hint of fanaticism on their faces, and they admired Liu Zhengbian even more.

Liu Zheng saw the stunned expression on Xu Huang's face, smiled mysteriously, and responded to Xu Huang.

"Haha, Brother Xu Huang, now you know how powerful I am, but I can tell you that my strength has not grown much, and the reason why I was able to tie with you on the war horse is actually thanks to an artifact I recently researched."

"What artifact?"

Liu Zheng said this, which made Xu Huang feel even more surprised, and immediately asked rhetorically.

"I can't tell you this thing for the time being, I'll share it with you after I study and improve it, once it is popularized, Brother Xu Huang will definitely be able to improve a lot again with your strength!"

This is not Liu Zheng's random speculation, according to the battle he had with Xu Huang just now, he could probably imagine that if Xu Huang also had stirrups, and after mastering the use of stirrups, Xu Huang's riding skills would be greatly improved on the war horse.

When the time comes, he can fight against enemies who are much stronger than him, after all, even a low-end figure like Liu Zheng can tie with Xu Huang, if Xu Huang also has stirrups, maybe he can compete with Lu Bu.

"Okay, okay, since you can't tell me for the time being, then I won't ask more, but Qu Shuai, you have to study it quickly, I'm very curious about you."

Xu Huang didn't ask much, and after finishing the battle with Liu Zheng, he began to teach those cavalrymen again.

And because Liu Zheng himself tried the role of stirrups, he decided to make another wave of modifications on the basis of his own experiment, so that it could be put into mass production.

But soon he encountered a new problem.

After several days of continuous building iron tire bows, the pig iron that Liu Zheng had collected these days was finally exhausted, and he soon had no way to continue to build new weapons.

Not to mention building stirrups, even continuing to build an iron tire bow can't support it.

The remaining pig iron is enough to be used for two days, even if Liu Zheng continues to collect some iron tools in these two days, and then melt it into new pig iron, he will not be able to complete the construction of the 1,000 iron tire bow he needs.

After all, although the iron tire bow is only a bow, the pig iron required is not much, but the pig iron used on the iron tire bow can consume much more than ordinary weapons.

The pig iron of these iron tire bows has been repeatedly quenched, and enough pig iron is quenched until only the last small part of the essence is left, and then it can be finally formed, so a large part of the iron slag is removed.

This is why Liu Zheng's pig iron here is consumed so quickly.

Without pig iron, it is impossible to continue to build iron-tired bows, and stirrups are even less to think about.

What to do?

The only way is to buy it like other princes, but Liu Zheng doesn't have much money, and it is also a problem to buy pig iron in a big way.

And even if he is rich, as a remnant of the Yellow Turban, he is only afraid of the official army, and he will not sell it to him.

But if a large amount of pig iron raw materials cannot be obtained in a short period of time, Liu Zheng's plan to build an iron tire bow and stirrups will be shelved, so the stirrups he researched will not be able to bring a great increase in the combat power of Liu Zheng's men and horses for a while.

Just when Liu Zheng was still worried about the matter of pig iron, Zhou Canghuo found him in a hurry.

"Qu Shuai, I have something important to report!"

As soon as Liu Zheng saw Zhou Cang coming over in a hurry, he immediately put down the matter in his heart for the time being, looked at Zhou Cang, and asked with concern.

"Brother Zhou Cang, what's wrong? What's going on? You look like you're in a hurry, as if you're in a hurry to find me. ”

"I do have something to look for you, but it's not too much of a hurry."

"What's the matter?"

"What else can there be, isn't it just that we are imprisoned in the dungeon, those officers and military officials, if you want me to say that I can cut them directly with a knife, so as to save us from wasting our food."

As soon as Zhou Cangyi said, Liu Zheng suddenly realized that he remembered Qin Jie and Cai Mao who were locked in the dungeon by him.

Just the two of them, because Liu Zheng caught them in Caiyang City before, he did not hand them over to the Yellow Turban Army, but detained them privately.

Then they were imprisoned in the dungeon of Runan, and after a few days, Liu Zheng forgot about them, if it wasn't for Zhou Cang to mention it, who knows when Liu Zheng would remember that there were still such two people.

"What's wrong with them? Don't worry about them wasting food, just give them a bite to eat a day and not die of hunger. After all, they are captives, and they still expect us to serve with big fish and meat. ”

"I think so too, but just now the people below me came to report that Cai Mao, who felt that this kind of life was hard and wanted to talk to us."

"Talk to us, what are you talking about? Could it be that he still expects us to release him? ”

"Who knows? Qu Shuai, if you want to see him, go see him, if you don't want to, don't care, he seems to say that he wants to, spend money to buy his life. ”

Zhou Cang's unintentional words made Liu Zheng's eyes light up suddenly.

At this time, he was worried about how to get a large sum of money, which would allow him to continue to buy pig iron and forge new weapons.

Now Cai Mao's words, didn't it just give him a chance to make money?

Thinking of this, Liu Zheng immediately became interested, and then urged Zhou Cang.

"Hurry up, take me to see Cai Mao, how did I forget him, this guy is a God of Wealth, really, if you want to doze off, you will send us a pillow."

Liu Zheng excitedly asked Zhou Cang to lead the way and walked all the way to the dungeon.

I saw Cai Mao and Qin Jie, who were imprisoned in a dim and stinking prison.

Unlike Qin Jie, who is not afraid of life and death and has a cold expression, Cai Mao is not so downright about life and death, he is even less courageous, and he is abused like this all day long, so naturally he can't stand it.

As soon as I saw Liu Zheng's re-entry, it was immediately like seeing a life-saving straw.

immediately shouted at Liu Zheng.
