In addition to making gunpowder, Lu Xiaoyu also ordered craftsmen to build a fire-breathing fierce fire oil tank in advance. The Pen Fun Pavilion www.biquge.info Fierce Fire Cabinet uses fierce fire oil as fuel, and the raw material of this fierce fire oil is the oil that Lu Xiaoyu didn't know how to extract before.

Here is a cabinet made of wrought copper, the cabinet has four legs, there are four copper pipes, and the pipe is horizontally placed with a pump, which communicates with the oil tank. The front part of the pump is a "fire building" with ignition powder inside. When in use, the red-hot cone ignites the ignition powder in the "fire tower", and then pulls the pump vigorously to put pressure on the air in the oil tank, and then causes the fierce fire oil to burn into a flame when it is sprayed out of the "fire tower", so as to burn the enemy and its equipment.

This weapon is effective against Lu's armored fighting vehicles, which are somewhat weak in close attack, and can attack with fire at close range, preventing enemy troops from breaking through obstacles and destroying the vehicle.

In fact, Lu Xiaoyu had thought about inventing these two new thermal weapons like this before, because he went to Guangling to transport cotton cloth so that the soldiers could change into light cloth armor to fight with the enemy at a long distance, rather than hand-to-hand combat, and the Southern Chu soldiers of the Yi tribe wore heavy armor and fought with the enemy. This is not to leave a way back for yourself, because once the development of thermal weapons fails, this cloth armor will not be able to withstand the practical iron armor at all, and can only be slaughtered by others.

The first gunpowder made was so successful, which also made Lu Xiaoyu a little unexpected. However, unlike the Haikou boasted by Lu Xiaoyu before, it is said that explosives can level the mountains and still need a sufficient amount, and now the amount is not enough to achieve it by constantly improving the quality.

What is there that can increase the power of gunpowder? Although Lu Xiaoyu thought of a lot of modern craftsmanship, many of them required a lot of equipment, which could not be realized at all in ancient times. Lu Xiaoyu carefully recalled the knowledge about chemicals he had learned when he was a student, and finally made him think of a relatively simple and easy-to-make potassium chlorate, with which it would become faster when explosives were detonated.

In fact, potassium chlorate was very useful for ancient societies, and it could be used to make matches, draw fires, primers, etc. Electrolysis is necessary to prepare it in modern times, but after all, when Lu Xiaoyu was admitted to the university, he almost got a perfect score in chemistry, and he participated in various chemistry competitions, so he could also prepare it with chemical methods in ancient times. The precipitation method only needs raw materials: potassium chloride, lime water, and chlorine gas.

It's just that some things still need to be found slowly before they can be added to the explosives, and they need to be constantly proportioned, after all, this powerful explosive has poor stability and may spontaneously ignite and explode anytime and anywhere.

If you have an idea, you have to implement it, Lu Xiaoyu was just about to go back to Qiantang to study the manufacture of cloth armor, and at this time, a letter also came from the palace of Wuyue in Qiantang.

"Xiaoyu, an old friend Xiang Yu has visited, and I have important matters to discuss, so I will return quickly."

Xiang Yu? How could he come to Wuyue Palace, didn't he go to Jingzhou City to buy an official before? Why did he come to King Wu Yue's mansion again this time, this is still a letter from King Wu Yue, indicating that he has already met Xiang Yu. With his identity, he also attaches so much importance to Xiang Yu, it seems that Xiang Yu is mixing well now.

Anyway, now I am going back to make cloth armor, and the manufacturing of cloth armor needs to be completed quickly, and here Lu Xiaoyu explains all the affairs in the army. Especially for the training of the Flying Tiger Elite Team, Lu Xiaoyu deliberately referred to the modern special forces-style physical training method and special psychological quality training, which he had instructed Ying Buyi before he was relieved to take Han Xin back to Qiantang.

"Brother Xiaoyu, don't come unharmed." Wu Yue Wangfu Xiang Yu waited for Lu Xiaoyu for a long time.

"Brother Xiang, last time, when I came back, you didn't say goodbye, and you didn't show up for a long time, and my foolish brother missed you very much." Lu Xiaoyu saw that Xiang Yu was already wearing a high hat and a gorgeous costume on his head, it seemed that he was indeed mixing well in the court, no wonder even King Wu Yue was in a hurry to summon him back.

"Xiaoyu, I didn't expect you and Minister Qincha to know each other for a long time, so from now on, everyone will be their own people. If there is anything that the minister needs from us, please ask. You came from afar, and we have nothing to send in the mountains and wilderness of Wuyue, so we can only send some special products. One of these three boxes of specialties is for you, and the other two boxes are for your father-in-law, please smile. "It turns out that Xiang Yu is now Tong Zhongxian's righteous son, and now Emperor Xuanhe ignores the government, Tong Zhongxian covers the sky with one hand, and Xiang Yu can be regarded as a chicken dog ascending to heaven, no wonder King Wu Yue also has to give him three points. However, how could this eldest brother be reduced to the point of recognizing a thief as his father, this Tong Zhongxian is a big traitor, doesn't he know? Lu Xiaoyu's mind was full of doubts.

Xiang Yu didn't feel the slightest surprise when he saw that King Wu Yue had asked a few servants to come out carrying three heavy boxes. Gently lifted one of the chests, and there was a flash of gold inside. Xiang Yu was still unmoved, but he did not refuse to accept it in full, which made King Wu Yue a little clueless. Lu Xiaoyu was also a little surprised in his heart, this King Wu Yue had never seen him give away gold so generously, and Xiang Yu did not show his intention. But from his expression, it can be seen that his temperament is completely different from before, and he feels less chivalrous, but more traitorous like Tong Zhongxian.

"I don't know what Lord Xiang is saying about Wu Yue's trip this time, why did he wait until my virtuous son-in-law Lu Xiaoyu was present to announce it."

Do you have to wait until I get back to make an announcement? Lu Xiaoyu was even more confused, this Lord Qincha was doing things for the emperor, could it be that the emperor wanted to summon him.

To tell the truth, Lu Xiaoyu still wants to become a virtuous minister who assists the emperor, but seeing that Emperor Xuanhe was mediocre before, he almost died in the Jin Shuibao Change, if it weren't for his letter to bewitch the Khitan Emperor, maybe Southern Chu and the Khitan would not have the opportunity to sign a peace treaty, and Emperor Xuanhe would directly become a prisoner, and King Wu Yue could also take this opportunity to become the new Emperor of Southern Chu, maybe now his status can be above tens of thousands of people. It will not make the current Khitan completely suppress the situation of Southern Chu, and Master Li Mi will not be framed by traitors and imprisoned.

Now there are only two points that give Lu Xiaoyu a reason to help Emperor Xuanhe deliberately sabotage King Wu Yue's plan. One is that although King Wu Yue has the posture of a virtuous king on the surface, but in fact he only wants to plot a rebellion, and he is also a fish and meat villager, compared to the stupid Emperor Xuanhe, King Wu Yue became the emperor, Lu Xiaoyu didn't know what greater oppression the people would suffer, and the other was that he could have lived and flew with two of his beloved women at the same time, but he was broken up alive, even if he is now his father-in-law, Lu Xiaoyu does not recognize such a ruthless person.

"Oh? Master Xiang, what's the matter, even the small people have to listen to the order together? ”

"Xiaoyu, you and I are brothers, why bother to see each other, just call me big brother. Actually, it's not much of a big deal. It's that the emperor values your younger brother's talent and wants to be summoned to the palace. In addition, the prince of Wu Yue also went with him, the emperor said that he hadn't seen Brother Wang for a long time, and he wanted to catch up with you! Xiang Yu said with a pleasant face.

It seems that Tong Zhongxian's side is going to do it! King Wu Yue and Lu Xiaoyu thought of each other this time, glanced at each other, and felt that the two were on the same front for the first time.
