The battle for Tushan has become the key to a battlefield, Yang Wanchun gave his life to the trebuchet to smash, trying to destroy Tushan, Liu Xu also defended this place here, and the trebuchet here was also smashing down the city wall frantically.

Consumption is not what Liu Xu is considering at all now, the utensils are dead, the people are alive, and he thinks it is too cost-effective to use a few trebuchets in exchange for hundreds of Goguryeo soldiers.

Xue Rengui has been patrolling the battlefield, although Yang Wanchun screamed fiercely, but he knew his role deeply, and since the siege began, he never showed up easily. Such a beheading operation was obviously a failure, and the soldiers of Goguryeo, in order to prevent the soldiers of the Tang Dynasty from sneaking close to the city wall, even if it was dark, the moat was still bright, so that Liu Xu's plan to secretly cross Chen Cang was completely lost.

"Sacrifice is necessary, people will die in battle, Liu Xu, send 500 people over, with the belief that they will die, pile up gunpowder at the gate of the city, and explode it directly, with our armament, street fighting, the Goguryeo people have no chance of winning at all."

Li Ji saw that Liu Xu still had a problem, he cherished his soldiers too much, as long as it could be solved with money, he would never choose human life, such a person was actually not suitable for being a commander, and perhaps because of this, the emperor has never handed over the power of the generals to Liu Xu's hands. Li Ji can see that when Liu Xu kills foreigners, he is not soft at all, but once the soldiers he leads are injured, this guy will retreat, if it is his own people, he will definitely choose to send someone to cross the moat with explosives on his back, bury the explosives, and then ignite them directly, as for the people in the past, whether they can or come back, there is no need to think about it, in their opinion, as long as they go to the battlefield, they should have such an awareness!

"I know, but I always want to save some people for our Tang Dynasty, Emperor Wu of the Han Dynasty, who fought all his life, has been fighting all his life, and has carved a huge territory for my Huaxia, but you also know that throughout his life, my Chinese clansmen have been sharply reduced from tens of millions to two million, almost we have conquered foreign races, and we have also disabled ourselves! So, I want to try, can I Liu Xu make a demonstration, not only a sneak attack, but a large-scale offensive battle, can we also sacrifice fewer people, Datang has no shortage of territory, lack of people, even if we conquer the whole world and no one manages it, isn't that empty talk? We can make money again, things are gone, we can do it again, but people are gone, that is gone, not to mention regeneration, giving birth to children, that is also a life for people, a woman gives birth to a doll, that is to die once, I don't know what other people think, but my wives and concubines, I will never allow them to suffer like sows! As long as I, Liu Xu, am still in Datang one day, I hope that I will do something for these people, I Liu Xu has no parents, I know, a child does not have the pain of parents! I hope that the soldiers I led can go back to be fathers and the women in the family can also be mothers in peace! ”

Li Ji paused, and then couldn't help it.

"You, hehe, okay. It's just that, Liu Xu, you remember, this kind of consumption also has drawbacks, financial consumption is equivalent to aggravating the burden of the people, Yang Guang is also an eloquent monarch, but unfortunately in the end it fell on top of the finances, the money is gone, the people's lives are hard, there will naturally be resistance, you also know, although the world seems to be calm today, but the water in it is also very deep, there are different hearts, but there are more than one or two, even, many people, originally had no ambition, but they couldn't withstand the push of their subordinates! ”

Liu Xu gritted his teeth and nodded. When people live, what life they live, the previous people, all had a hard time, and they couldn't even eat, but ten years have passed, many people are used to eating and drinking, not to mention going back to the past, even if the days are harder, many people will not be willing. The chaos in the world is never determined by the rebel officials, it is the people, and when the people are in chaos, then the world will be really chaotic! Therefore, Li Ji's words are actually very realistic, if Liu Xu starts a war with financial attrition, others will definitely follow suit, but how many Liu Xu are like this in the world? He was able to get his capital back when he fought because he had a huge merchant group behind him, and other people came like this, so could he not be chaotic? Do they have the ability to do that too? Once such a sharp consumption of finances becomes a habit, no matter how powerful the empire is, it will be dragged down! Therefore, Li Ji is also reminding Liu Xu that he must not make a decision so easily, because such a move is destined not to be approved by the current court. Even, maybe at this time, there is already a voice of impeachment, sounding in the court!

"Uncle Li, don't worry, I know, Liu Xu won't open a gap that can't be plugged."

With a long sigh, Liu Xu stood in the wind, Xue Rengui rode back again, and nodded at Liu Xu, Liu Xu knew that the opportunity had come. He breathed a long sigh of relief and clenched his fists.

"Let's go!"

What to put?

Li Ji looked at Liu Xu's face, a little curious, but when he saw the organ bird on the dirt mountain, Li Ji knew, what is Liu Xu's real purpose, since Li Tai's experiment, people know that some things, like birds, can glide for a long time and distance with wings, this distance, as long as the calculation is accurate, he can land well to the designated place, much like a paper kite, but no one has ever thought that this kind of thing, can be tied with gunpowder and fire oil underneath!

"Since Yang Wanchun wants to defend to the death, behind the city gate, there must be a lot of things, even if the city gate is blown up, we may not be able to enter, but the city wall is different here, as long as a section is blown up, we will definitely be able to rush in, Yang Wanchun thought that I piled up the earth mountain just to build siege equipment, he didn't expect that my real purpose was to blow up the city wall!"

Each of the 500 soldiers of the Shenji Battalion has a trap bird in his hand, and there is a spare one in the back, and the lead wire is also calculated, and then wrapped in oiled paper, and fine threads are woven outside, just to prevent it from being blown out by the wind. Now there are thousands of trap birds, and they are the soldiers who are going to die in place of them!

"Hehe, the old man goes to sleep for a while, if you pick Yang Wanchun's head, remember to give the old man a look."

Li Ji shook his head helplessly, this kid's heart is always something strange. He was thinking, maybe the future battles will be like this, if Datang's skills are more proficient, Liu Xu's ideals may not be realized!

Liu Xu smiled slightly and stood on top of the Chinese army again.

"Attack!"

With an order, five hundred ballistas that were ready to go had already shot out the gunpowder trap birds directly, the angle, wind speed, all of them had been calculated and estimated, and the experiment was not once or twice, and the first actual battle on the battlefield depended on their outbreak!

The organ bird that covered the sky and the sun completely stunned Yang Wanchun, he didn't know what it was, wild goose? During the Three Kingdoms period, Zhuge Kongming's wooden ox and flowing horse were extremely mysterious, and what is the current thing?

Also confused, there are also Goguryeo soldiers, what are these, they have never seen them, no, they should say that they have never heard of them! At this moment, the battlefield was almost quiet, and they all looked up at the trap bird that fell in a beautiful arc, a mistaken trap bird, and fell with a click and hit the chest of a soldier who stretched out his head to watch, and the soldier fell in disbelief, and the surrounding soldiers were frightened and let go, but they still didn't understand.

What is it? Alternative trebuchets? The stone is too heavy to hit, so use this thing? If you lie down, isn't it still useless? Are the Tang people stupid? Kill people with such beautifully crafted birds?

The burning sound of the gunpowder fuse and the white smoke rising from behind finally made Yang Wanchun wake up a little, and his whole body began to tremble, he wanted to shout to retreat or lie down or something like that, but before he opened his mouth, those soldiers who slowly stepped forward to check felt a loud noise that shook the sky, and a bamboo tube in the bird exploded, and the things contained in the iron pieces were splashed everywhere, and the soldiers around him, even if they were wearing stiff armor, were not enough at all, and they were directly blown to pieces, farther away, It was also directly swept away by the air wave of the explosion, and some outside, the eardrums buzzed as if they were being beaten by a big drum in their ears, and then, touching their ears, the blood on their hands. Then he shouted frantically, only to find that he couldn't hear anything.

"The instrument of the Tang Dynasty! Gunpowder! ”

Yang Wanchun, who was prostrate on the ground, trembled, his teeth were about to be crushed, his eyes were incomparably huge, and a piece of iron flew along his eyebrows, bringing a hot pain to his forehead, and in the blink of an eye, he found that blood was flowing down!

"Liu Xu, you are a demon, a murderer! If the old man doesn't kill you, he swears not to be a man! ”

He finally puffed up the anger in his chest again, suppressed the fear in his heart, and roared angrily, he knew that the soldiers at this time had been stupid, they were stupid, they were stupid, for these unknown and cruel murderous things, they couldn't lift a trace of fighting in their hearts, he needed to use his anger and murderous aura to wake up his soldiers! Otherwise, Anshi is finished, he is finished, Goguryeo, it will be finished, he absolutely doesn't believe it, Liu Xu only brought such a little gunpowder he saw!

The idea was good, and Yang Wanchun was decisive enough, but before the words came out, he heard an explosion louder than his voice, and then, the earth shook! He remembered, how could the gunpowder only be carried by a trap bird? Those are all with him, Liu Xu is not to blow up his own soldiers, he is to blow up the city wall!

Run!

Absolutely can't lie on his stomach, with the power of that gunpowder, Yang Wanchun can think that so many trap birds can definitely cross the city wall! But could he think of it, and what others could? People and animals are the same, when there is an earthquake, the first choice must be to lie on their stomachs, trembling and lying on their stomachs, thinking that this is the punishment of the heavens. What's more, you can't stand steadily.

"Run!"

It took a great deal of effort for him to stand up, and despite the loud noise outside, he used all his strength, and then, the gunpowder exploded again, and he looked at the wall under his feet in horror, tilting a little!

Huge smoke and dust, billowing up, on the earth mountain, there are no soldiers for a long time, Liu Xu also found that he underestimated Li Tai's gunpowder that has been improved again and again, this thing, and the explosives of later generations have been getting closer and closer, five hundred trap birds, it has almost collapsed the city wall, there is not so much use in the back, some gunpowder, even in the air directly exploded, sawdust flying, at this time do not run, their own people will suffer!

Fortunately, the people on their side are all trained, and they can't wait for their parents to give them a few more legs, where will they look back to see what is going on over there, panting and running to a safe distance, they fall headlong, and when they look back, there is a scene of the Goguryeo city wall slowly collapsing.

"it! Whoever dares to stop Lao Tzu from using this thing in the future, Lao Tzu will have to kill him! You don't need this thing on the battlefield, it's fun to hide it in the treasury! ”

Li Ji couldn't sleep, his eyes were glaring angrily, his hands were trembling, he didn't expect that the power of this thing was already so huge!

"Order, kill! The walls have collapsed, the moat has been blocked, what a chance! ”

Li Ji tried to stabilize his emotions and walked to Liu Xu's side, Liu Xu slowly shook his head.

"Wait, wait."

"What are you waiting for?"

"Uncle Li, you don't know, this thing isn't 100% blown up, just in case..."

The mouth just said, and then there was a loud bang, sure enough! And the squibs, which are only now exploding!

The trembling and majestic city wall, after the explosion of this life, fell down again due to the co-shock, and Li Ji trembled all over, and his eyes were fluttering.

"Zhang Yide roared and broke the bridge, this is also ah, but now it's okay, hehe, Uncle Li, you give the order, the boy's task is over."

Liu Xu sat down decisively, what he wanted was to give credit to his soldiers, but it was not this command, let alone him Liu Xu himself to receive this great merit. What's more, he has never taken over the responsibility of Li Ji's general management, so naturally there is no talk of a temporary change of coach.

Li Ji looked at Liu Xu with some hesitation, saw him nod seriously, then smiled and patted him on the shoulder.

"Okay, this credit, your Uncle Li received it for you, don't worry, the soldiers you brought should have meritorious deeds, who the hell dares to meddle and not give it, I will go to the court hall and slap his ears in person!"

Liu Xu nodded with a smile, Li Ji stood up, waved the horse lance in his hand forward, turned over, and rode on horseback.

"Sons, the battlefield is prestigious, the time has come to worship the marquis, kill!"
