Cao Xing had seen Liu Qubei, and when Liu went to Yanmen that time, Cao Xing also took him to visit the kiln, at public expense. Therefore, he went to the city to scold and returned and told Lu Chen that Liu Qubei was really in the city, and Lu Chen accelerated the pace of attacking the city.

Lu Chen's purpose is very simple, to blow up Liu Qubei, or blow up the earth city to kill Liu Qubei and capture Liu Qubei alive, no matter which option it is, it is just a trick to capture the thief and capture the king first. It is good to succeed, but it is also necessary to achieve the set siege goal - to scare the enemy's courage, and then force the other side to compromise and end this asymmetrical and meaningless war.

Lu Chen couldn't afford it.

Too few people can't afford to consume, not enough inventory can't afford to consume, and too little time can't afford to consume.

The turquoise smoke was like a tide, and at the moment when it flooded the city under the impetus of the cold wind, Lu Chen and the others rushed to the bottom of the city. The arrows from the towers became more and more sparse and soon stopped, and wails and screams were heard from above, as if experiencing some kind of horrible despair.

The smoke evaporated by the heat of burning the liquor is highly toxic, and inhalation can cause nausea and vomiting, headache and suffocation, and in severe cases, mental confusion. Although it can only poison a very small number of people, it can make people lose the power to resist.

The appearance of this thing was an accident, and Lu Chen didn't expect that Wuzhu's maid, that is, the princess Fatima from the Western Regions, would actually refine hydrochloric acid, in fact, it is not surprising that the Arabs have made many novelties in history. Lu Chen and Fatima came up with nitric acid and sulfuric acid, which were originally intended to be used as cloth bleach. Later, when Lu Chen was making soap for Zhen Mi, he got glycerin from animal fat, and later, nitric acid met glycerin...... As a result, Fatima blew up the two lambs and was severely whipped by Uzhu. But this is not important, the important thing is that this accident allowed Lu Chen to discover the new world!

Nitroglycerin, the thing that made yellow explosives in later generations, is a sharp weapon ten times more fierce than black powder!

It's just that Lu Chen did many experiments with death row prisoners in the coal mine, and after all, it was difficult to control nitroglycerin and it was very easy to explode, so Lu Chen did not make a bomb. But he has developed a method of storing nitroglycerin, that is, to knock nitroglycerin into a glass bottle, and then put the glass bottle into the wine jar, the glass bottle is tied to the bottom and mouth of the altar by an elastic rubber band, so that the collision can be prevented and the shaking can be weakened.

Lu Chen took more than 200 broken captives who had become foot soldiers, put five iron boxes the size of urns under the city gate, lit the fuse and fled quickly. Then I heard a boom, and the small tower at the head of the city jumped, and when it fell, the city wall and gate below had turned into a scattered loess.

This is the simplest yellow explosive, right?

The five closed iron boxes were full of black powder, and a bottle of nitroglycerin was placed in the middle of each of the gunpowder powder, which ignited the fuse to detonate the gunpowder, which was only to cause the nitroglycerin explosion in the middle.

Breathing a little uncomfortable, Lu Chen tightened his leather mask, waved his hand and led his men into the city.

The leather mask was made in advance, and originally came to Yanmen to demonstrate the power of nitroglycerin to Huchuquan, and the mask of charcoal filtering the air naturally had to be done to ensure safety. Lu Chen planned to use this to increase Huchuquan's courage to fight against Xianbei, and use this as a bargaining chip to fool the Huns and Xianbei to merge with the Xianbei people, and try his best to preserve the strength of Yanmen.

However, the situation is very different now, and fortunately, these preparations can still be used, but in a different way.

In the city, except for those who died by trampling on the city tower, the rest of the Hun soldiers all fell to the ground and struggled and wailed, and many people choked their necks with their hands and felt painful, and they couldn't even scream. At this moment, it is impossible for them to raise their weapons to resist, and they don't even have the eyes to stop them, after all, the fear of death has overcome everything.

Lu Chen was leading people to search, and Cao Xuan shot a red feather arrow with a round arrow back in the direction of his own formation, which was a signal for the thirty soldiers who stayed behind to stop the poisonous smoke. If you don't stop, the charcoal mask won't be able to hold up, and when the time comes, all these people on your side will be poisoned, and it will be a big game.

The green smoke soon stopped, and Lu Chen's search also stopped, except for catching a few Hun generals, nothing was found, and Liu Qubei fled.

Lu Chen didn't regret it too much, it was luck to catch it, and there was a trick if he didn't catch it.

The Hun generals were escorted back, and they were directly recruited without any interrogation process, probably because they had never seen such a terrifying "witchcraft" and were frightened. According to them, there were 3,000 soldiers guarding the gates and in the city, and that's not counting the 3,000 remnants of the previous defeat, but a very small number of them fled, most of whom were overturned by the poison gas. Some people saw that Liu Qubei was also overturned by the explosion at that time, and he even inhaled some poisonous gas, but his guards grabbed a few horses and took him away.

"What's next? Xiao Junhou, a certain soldier will go directly into the city, right? ”

Cao Xuan didn't think it was enjoyable, he won this battle, but it was too boring to win, he still liked to kill with real knives and guns.

Lu Chen ignored him, looked at the broken city that was still surrounded by green gas, and said, "Wait." ”

Lu Zhan, who was wiping Lu Chen's armor with spirits, asked, "What are you waiting for?" ”

Lu Chen said: "Wait for them to surrender." ”

……

Finally escaped back to the big tent of the Chinese army, Liu Qubei and the scribe surnamed Zhao retched on the ground, but a few guards were in good health and had not yet fallen, but they were also very hot and collapsed.

Before the doctor was invited, Liu Qubei and the others eased up.

The power of nitroglycerin is more explosive than toxic, its gas is not deadly, and they also inhale a small amount, just breathe more fresh air, and the body will naturally improve.

Even so, Liu Qubei was also afraid, and hurriedly summoned the army to go to the direction of the city gate to encircle Lu Chen's army, and checked the situation by the way. The information soon arrived, which made Liu Qubei feel at ease, but also suspicious and uneasy. It turned out that the Hun soldiers who were put down by the poison gas were alive again after a stick of incense, and Lu Chen did not attack the city and retreated. It's just that the bombed city gate is irreparable.

"Mr. Zhao, you are well-informed, what is that green smoke?" Liu Qubei couldn't help but ask.

"Ahem...... I haven't seen it in the next. "Mr. Zhao is frail, still coughing, and gasping for breath is a little difficult.

"The one who blew up the castle tower was gunpowder?"

"I don't know, gunpowder must not be so powerful......"

"It seems that Lu Chen'er has made a new weapon, these two things are really terrifying! In my opinion, can I win with 40,000 iron horsemen? ”

"This ......"

Mr. Zhao sat for a while, feeling a little more relaxed, but hesitated and didn't know how to speak. Liu Qubei was obviously out of order, staring at Mr. Zhao anxiously, asking him for guidance.

"Current events are different."

"Mr. said that you want me to make peace with that Lu Chen'er? How does this work? He is the son-in-law of Hu Chuquan, how can he serve me as a single Yu? If not, why would I raise troops to the north? And why cede the Hetao to those Xianbei barbarians? ”

"Hey......"

Mr. Zhao sighed and didn't answer again, he understood that he had already negotiated with the Xianbei people, and the right Xian Wang was also trying to see the dagger, and it was bound to be difficult to return to the previous state, and Liu Qubei had no way out.

Zhao Keli was the chief bookkeeper of Hedong County, although he was not a famous family, but he also had a small net worth, and he was also the largest family in Fushi, but unfortunately the world collapsed and Fushi was stolen by the Huns. In this way, in order to preserve the family and seek higher interests, he became Liu Qubei's staff, and even did not hesitate to give his most beautiful daughter to Liu Qubei's second son as a concubine.

He has already staked all his family on Liu Qubei, and there is no way back.

Now, what told Liu to be humble was not the 300 Yanmen cavalry outside the city, but the new weapons they made. Judging from the combat effectiveness they are currently showing and the strange and terrifying way of fighting, even if they send 30,000 cavalry, they may not be able to leave Lu Chen behind, in case Yanmen comes to attack with this new weapon, it will be the time for the Huns to exterminate the clan. They did not know how difficult it was to produce, preserve and transport nitroglycerin, and they were horrified that it could be made and used on a large scale like gunpowder.

In addition, the rare gunpowder in Liu Qubei's army came entirely from Yanmen, so it is said that almost all of their iron tools, horseshoe, stirrups, salt, etc. were exchanged from the horse market in Mayi, and they relied on Yanmen very much. There are only two choices, either to have a good relationship with the Lu family's father and son, or to destroy the Yanmen Lu family.

Now it's hard to ride a tiger.

The house leak happened to rain overnight, and at this time, a member of the staff rushed in and shouted, "King Youxian, something is wrong...... I just got the news that all the Xianbei people in the post tent are dead, and there is no one alive! ”

Liu Qubei almost spurted out a mouthful of old blood, and it took a long time to calm down and ask for details.

It turned out that when the battle broke out outside the city, some of the Xianbei people in the post tent vomited blood one after another and died, although Liu Qubei's generals found a doctor, but still did not save a person, within half an hour, the Xianbei envoy died a fine light.

"What a trick! Hahaha......"

Liu Qubei smiled, laughing weirdly, but then he stood up with a shaky and said to Zhao Keli: "Mr. Zhao, help this king write a letter to Lu Chen, I promise to withdraw from Meiji City, and I will not fight for the position, and ask him what price he can give." ”

Zhao Keli shook his head and left.

There was no other choice, if they had hoped to unite with the powerful Xianbei to counterbalance and blackmail Lu Chen, now, there was no possibility of even this method being realized. None of the Xianbei envoys died in Meiji, and now Meiji City is in the hands of Liu Qubei, no matter what they say, it is impossible to explain it clearly, and the alliance with Xianbei can only fail.

Fortunately, now Lu Chen only has three hundred soldiers, and even if he has a big killing weapon in his hand, it is impossible to swallow all the 40,000 troops of the Right Xian King. On the contrary, if Liu Qubei jumps over the wall in a hurry, he may be able to kill Hu Chuquan who is trapped in the king's tent first, which is the last bargaining chip.

……

Three days later, Liu Qubei's 40,000 iron horsemen and his 15,000 Huchuquan subordinates all withdrew to ten miles south of Meiji. The 20,000 troops of the Tokh Department from the west also entered the ten miles south of Meiji City, and this army, which was not long ago beaten by Liu Qu, did not dare to approach the troops of King Youxian to camp. Hu Chuquan's remaining 10,000 soldiers and horses regained control of Meiji City, but Lu Chen didn't think that Hu Chuquan could defend Meiji if he really fought. The tens of thousands of troops of other tribes around Meiji also roared away, as if they had never come.

The catastrophe of Huchu Spring, like rain and sunny weather, was perfectly resolved.

That night, Lu Chen also entered Meiji with the handsome army, and after rewarding the nameless who had carried out the perfect assassination mission, he went to the king's tent to appease the frightened old Shan Yu. The aging Hu Chuquan greeted Lu Chen fiercely, drank wine and ate meat in a big bowl, and almost called him a brother and a brother, if he hadn't been stopped by Wuzhu, the old thing would have planned to give a few of his beautiful concubines to Lu Chen for waste.

Early the next morning.

A unique wrestling match was held under the castle of Miji.

The rules of the competition are not special, they are all old tricks that the grassland boys are tired of playing, however, the prizes are more attractive, and the winner's reward is - Shan Yu.

Every leader of the Xiongnu tribe who was present felt that it was child's play, even a little insulting, but they had no choice.

Of course, the competition was held by Lu Chen, he had already negotiated with Hu Chuquan, the old man promised to hand over Shan Yu's position, and even passed the position of the clan leader to his son Ye Lixian, but he was willing to go to Yanmen to help his daughter herd sheep.

If Lu Chen came two days late, or if Lu Chen failed to break Liu Qubei's courage in a battle and cut off his alliance path, Hu Chuquan would be in a different place.

Therefore, Hu Chuquan, who has been in the name of Shan Yu for more than ten years, understands who is more important and who is lighter in the end.

Hu Chuquan may not be afraid of death, but he is afraid of death inexplicably, because he himself cannot lead the Xiongnu, but he will be regarded as a stumbling block for careerists, which is somewhat wronged. Moreover, what he was most worried about was the destruction of the tribe, so if Lu Chen could calm the disputes between the Xiongnu tribes and protect his tribe, he was willing to abdicate.

The final winner of the wrestling match became the new Shan Yu, but he did not have the absolute power to rule the Xiongnu.

The remaining tribes will send one to three representatives according to their strength to form a twelve-member elder group, plus the new Shan Yu, and each of the thirteen people will have one vote, and all matters will be decided by a joint vote.

For this decision, Liu Qubei took the lead in responding, and other tribes can participate in the decision-making, so they will naturally not object.

When he negotiated with Liu Qubei three days ago, Lu Chen gave Liu Qubei enough benefits, and of course gave him enough pressure. Liu Qubei did not object to the selection of new singles through wrestling, and other tribes naturally did not dare to make a moth.

Lu Chen gave Liu Qubei three benefits.

One is to provide the latest nitroglycerin bombs to his army, the quantity, one-tenth of the output of Yanmen. The second is to agree to the free trade between Liu Qubei's tribe and Yanmen, and to pre-purchase the wool skins of Tiefubu cattle in advance every year to ensure the harvest in drought and flood. The third is to sign an offensive and defensive alliance agreement, the two sides will not attack each other, and once one side falls into war, the other side must provide unconditional support.

Lu Chen's pressure on Liu Qubei was not small.

Yanmen would provide nitroglycerin bombs to other Xiongnu tribes, no more, no less, just twice as many as the Tiefu tribe. Moreover, because Lu Chen provided a lot of technical and economic benefits to the Xiongnu tribes, most of the small tribes had their hearts set on Yanmen, and even Liu Qubei did not dare to destroy this good situation, after all, smashing people's jobs is like killing their parents.

As for the Xianbei people? Don't be afraid!

Before he came, Lu Chen was still a little worried, but now, he was only afraid that there were not enough Xianbei people. Because, Lu Chen had promised the Xiongnu tribes that they could not only resist Xianbei's southward movement, but also counterattack Xianbei, and Yanmen would provide them with weapons in the form of loans and mortgages. The cattle and sheep and pasture they grabbed belonged to themselves, and the captured slaves belonged to themselves, and the surplus could be sold to Yanmen as coolies.

Looking at the red eyes of the Huns looking at the north, Lu Chen finally understood the madness and bloodiness of the colonial era in later generations.

It was a bit of a fluke that the whole thing was able to achieve such a successful outcome.

However, if Lu Chen was asked to choose again, he would only bring three hundred people to attack Meiji. After all, Lu Chen's father is Lu Fengxian, the number one fierce general of the Three Kingdoms! No matter what happens, you can't be cowardly, just do it! (To be continued.) )
