Later, Cao Cao finally understood the fall of Jibei, it turned out that Zhang Liao did not know where to transfer the archers, the bows and arrows in the hands of those archers not only had a long range, but also caused a fire, and it didn't take long to see the entire camp turned into a sea of fire, and then Zhang Liao rushed into the camp with the chaos of the army, and happened to meet Yang Jun, the prime minister of Jibei, but Yang Jun did not react, and was cut down by Zhang Liao under the horse.

Due to Yang Jun's death, coupled with the fact that the soldiers in the army had heard of Zhang Liao's name, the soldiers in despair surrendered one after another, which allowed Zhang Liao to recover the entire Jibei Kingdom.

"What kind of weapon is that bow and arrow that can ignite fire?" Cao Cao couldn't help frowning and said with a worried face.

Sima Yi also didn't know anything about this, and couldn't help but look at Cao Cao, and then they all shook their heads with a wry smile.

"From the ladder to the bridge, from the iron knife to the Mo knife, from the crossbow to the wheel is a catapult, as well as the mysterious weapon that can instantly collapse the city gate and this kind of bow and arrow that can ignite the fire, this Liu Qi's brain is really amazing, right? In addition, there is also the Juntian system, the imperial examination system, the study of Daxing County, the recruitment of government soldiers, and the establishment of nine official products, each of these measures is shocking, but each of them can play an incredible role, the king, it seems that we must specially train a group of secret agents, find a way to infiltrate Liu Qi's country, and find out the secrets of those mysterious weapons, even if they can't make them, at least they should have a precaution in advance, so they won't be as at a loss as now, right? ”

Sima Yi sighed softly and said to Cao Cao with a solemn face.

Cao Cao thought for a moment, then nodded, and said softly: "In this case, this matter will be arranged by Zhong Da, and strive to get the secret agent into Liu Qi's interior as quickly as possible, and then pass the news to us in a timely and safe manner." Anyone who is willing to be a secret agent will be named the marquis of Guannei, and as long as he has made a meritorious contribution to it, he will be rewarded according to the size of the merit, and the highest can be directly named the county marquis. ”

Not to mention that Sima Yi took the time to deploy secret agents in secret, but said that Xu Bing, the captain of the Tiger Guard's own army, personally arranged for the capable Tiger Guard soldiers to go down to the city that night. Lurking in the dark night, nervously monitoring the movements around him.

Around the time of the third watch, Xu Bing and his soldiers lurking under the north city wall suddenly heard a sound of gently stepping on the ground not far away, if this sound was in the camp, it was absolutely difficult to hear, but because it was close at hand, it was very obvious, as if many spring silkworms were biting mulberry leaves, and it was like a storm. It shakes people's eardrums and makes people tremble.

"Here we are." Liu Dazhu, who was beside Xu Bing, heard this voice, and couldn't help but turn pale, and said tremblingly.

"Exactly, it seems that this time the Chu army is about to move, so thinking about it, Liu Qi, the king of Chu, must be full of absolute confidence in their siege weapons, otherwise he would never make such a big move. Brothers, all be in good spirits. This time, we must find a way to see the enemy's siege weapons clearly, and if it is easy to move, we must immediately transport them to the hanging basket and let the soldiers at the head of the city pull them to the top of the city. If you can't move it, everyone will come forward and destroy the weapon. But as long as it is destroyed, it will definitely alarm the Chu army, and it is not terrible for us to die, but no matter what, someone must report the situation of this siege weapon to the king, Niu Er. You kid has a lot of research on machinery, so this task is entrusted to you, and once we find that the siege equipment is not easy to destroy, you immediately put it in your head, and then climb into the hanging basket and escape to the city. ”

Xu Bing's voice was very heavy, and he whispered with a stern face.

"No, sir, I'll stay, you go back." A man with a short figure but a strong man said softly.

Everyone knew that under the encirclement and suppression of Liu Qi's army, the soldiers who stayed here would die a hundred lives, but Niu Er was still willing to give this only chance to their commander, Xu Bing, who had always treated them like brothers.

But seeing Xu Bing, he couldn't help but scold: "Now is not the time to be angry, you are the only one among us who comes from a family of craftsmen, and only you can understand the siege equipment of the enemy army, if you go back, isn't our sacrifice meaningless?" ”

"No, the last general knows." Although Niu Er was very reluctant to be a deserter himself, he knew that Xu Bing was right, they could all spare their lives, but they must figure out this most advanced siege weapon, and then send as complete information as possible to Cao Cao, the king of Wei. Therefore, he had no choice but to agree with tears in his eyes.

After a short time, they saw a figure galloping over not far away, Xu Bing and they vaguely saw a person carrying a burden to the front, they were all surprised when they saw this, because they couldn't imagine that the enemy's siege weapon was just a burden, what kind of strangeness could there be, and it would make the entire city gate collapse?

But they didn't dare not intercept the comers, so Xu Bing waved his hand, and a group of sixty or seventy people silently dispersed, and the people were faintly surrounded in the middle.

After a while, the visitor stopped at the city gate, took off his baggage, and just as he wanted to make a move, he heard the wind around him, and immediately saw dozens of people outflanking him.

When the man saw this, he knew that the enemy had discovered his traces, and without hesitation, he immediately ran into the spur, only to see the man running like the wind, and in the blink of an eye he sprang out five or six feet, and then he raised his burden with both hands and threw it forward, and then he heard a bang, and the man actually threw the burden into the moat.

Now it was freezing cold, and even the moat was covered with thick ice, so although the man threw the burden into the river, he only threw it on the ice, and as long as they went down and scooped it up, they could still get the contents of the baggage. But the biggest problem now is that they need time, even if they don't count the time to kill, at least the time to go up and down the river to get the burden, and then send the burden to the city, right? And whether the Chu army will send people to come again during this period of time, no one dares to guarantee.

But despite this, they must also do this, because this siege weapon of the Chu army is very important, and they must get it.

Therefore, these people were automatically divided into two groups, one group of about ten people, surrounded the Chu army soldiers and started a fight, and the other group of people all jumped into the moat to find the burden.

The Chu army soldier was besieged by more than ten Wei soldiers, but he was fearless, drew his saber and fought to the death with the besieging soldiers.

In the middle of the night, the sound of weapons colliding was particularly eye-catching, even if it was ten feet away, it could be heard, but these more than ten guards could not control so much, although they paid for the lives of three soldiers, they still killed the soldier on the spot.

But then they heard the sound of a fierce clash of weapons in the moat.

"It's not good, the cunning-looking Chu army has already laid an ambush in the river." Hearing this, the faces of the more than ten Tiger Guard soldiers who had successfully killed people couldn't help but change greatly, and almost instantly decided to go down to support.

After all, the main purpose of their operation this time was to carry the burden in the moat, if they did not go down to support, in case the robe in the river was killed by the enemy, I am afraid that with a dozen or so of them, I am afraid that it will be impossible to regain the burden.

That's why they took the opportunity to go down to the aid of Paoze, and first concentrate on cleaning up the enemy troops in the river, even in the most conservative estimates, even if they were not the opponents of the Chu army's ambush, then they had to cooperate with their own soldiers and snatch the box containing the mysterious siege equipment first.

This is their top priority, and all of them can risk their lives in order to accomplish this mission!

But unexpectedly, when they all reached the moat, they found that the battle there was nearing the end, and their robes were almost slaughtered, and when they arrived there, they were immediately slaughtered by the superior forces.

Xu Bing is also one of the more than a dozen Tiger Guard soldiers, he watched his brother being surrounded and killed by the enemy, his heart was full of unwillingness, and he roared angrily to kill the surroundings, at this time he already knew that it was impossible for him to escape, and the task of recovering the burden could not be completed, he only had one thing left now, that is, to kill as many people as possible.

As a result, Xu Bing, who looked like a mad tiger, broke into the enemy group with a knife, and relied on his extraordinary skills to kill an enemy army like thunder. But when he swung his knife and slashed at the second enemy soldier, there were five or six knives around him at the same time, Xu Bing knew that he was going to die, so he immediately swung his knife and slashed at the enemy soldier closest to him, but he didn't expect the enemy soldier to snort, and then swung his knife to block.

Only heard a sound properly, Xu Bing felt the light of the knife in his hand, and knew that the knife had been cut off by the opponent's knife, and at the same time, five or six knives slashed into his hands, ribs, chest, abdomen, thighs and other places, making him lose his combat power immediately.

"This, what kind of army is this? It's so powerful! Could it be that Liu Qi's Xiao Guard Army and Praetorian Guard Army are among the two pro-military camps? ”

Xu Bing sat on the ground with a shocked face, although he was covered with blood, he was not dead for a while.

At this time, he heard a majestic voice: "Haha, for a broken stone, I didn't expect the Wei army to be so desperate, if they knew that our people had come to the city wall when they all came to the moat and ignited the gunpowder, I don't know how they would feel?" ”

At this time, Xu Bing knew that the burden that led them to the moat was only a stone, and he couldn't help but feel sad in his heart, and at this time he finally understood that the siege weapon that could cause great damage was originally called gunpowder, but he didn't know what this gunpowder looked like? He didn't know how the gunpowder had been so destructive, and the saddest thing was that even if he knew that the gunpowder was in storage, he couldn't bring it to the city, because he had dried up his blood and was about to die.

At this time, he faintly heard a shout: "Get down." Then he heard an earth-shattering bang, and knew that the gates must have been blasted open, and he lost consciousness...... (To be continued......)
