After Zu Zhao's army annexed Goguryeo with a state of devastating and decaying, many small countries and tribes in the north asked Zu Zhao to surrender, but only Xianbei and Wuhuan still competed.

The two countries formed an alliance army, and summoned several other small countries and tribes that were dissatisfied with the Han Dynasty, especially many countries on the Korean Peninsula, to form an alliance army of four or five hundred thousand people to fight against Zu Zhao, and also threatened to kill the Han people.

The alliance forces of the two countries began to invade Silla, but fortunately, Ma Yuan led his troops to defend it, so he reluctantly resisted it, but the queen of Silla, Jeon Zhiyu, had repeatedly asked Zu Zhao for help, saying that the Silla border was full of smoke, so that Zu Zhao quickly led his troops to quell the chaos.

Zu Zhao knew very well that once Silla was in turmoil, then Liaodong would be involved next, and the war must not be allowed to break out in the land of Liaodong, and if it is to be fought, it must be big in other places. Fortunately, the battle to annex Goguryeo did not cause any great losses to the army, and at this time, the soldiers' spirit was also there, and there were many people who shouted for troops.

Zu Zhao once again asked the imperial court, saying that Wuhuan, Xianbei and many other small countries had begun to form a strong large alliance army to invade the Han Dynasty, and asked for troops. The imperial court allowed Zu Zhao to be crowned as the general of the barbarians, and was sealed by him to let Zu Zhao send troops. At the same time, Liu Yu, the governor of Youzhou, also sent 10,000 troops and 8,000 war horses to support, not to mention heavy grain and grass.

In mid-September, everything was ready, Zu Zhao faced Zhang Pre and Yu Ban as the vanguard generals of the left and right, appointed Zhang Yuan and Zhao Meng as the commander-in-chief, appointed Chen Gong as the military division, and personally led 120,000 troops out of Xianbei. When he arrived in Silla, Quan Zhiyu had 50,000 soldiers, thousands of loads of grain and grass, a total of 170,000 troops, and marched mightily to Xianbei.

Xianbei knew that Lu Dao Zuzhao led a large army to advance towards them, and hurriedly summoned the generals to discuss the strategy of retreating from the enemy.

When there are dead generals in the army, they take the initiative to ask for battle, they are quadruplets, four are tigers and bears, and they pull out a thousand catties, the eldest brother is named Wei Tuwu, so that one hundred and eighty-two pounds of heavy hammers, and the courage is invincible, the second brother Wei Tuling, so that two Bluetooth sticks, try to ride on a horse, fly as a swallow, one person alone defeated twenty wolves, a battle became famous, the old third lieutenant was stunned, so that a machete, once went into the mountains to hunt and was lost and trapped for two months, survived by hand-to-hand combat with wild bears and tigers, shocked the entire clan.

The old fourth lieutenant Tuwen, calm and introverted, is a boy, once a pair of bandits injured his father, before the three elder brothers came back, riding a mount alone, there was an iron rod weighing 120 pounds into the thief's den, killed more than 500 bandits, came back with more than 500 heads, shocked the township, known as the death of the iron rod captain four.

General X in the army knows the ability of these four brothers very well, knowing that the old captain is powerful, but reckless, but he can listen to people's persuasion, the old second lieutenant is flexible, and can come and go freely in the million army, no one can be, but he has a stubborn temper, as long as he believes in the things, no one can persuade him, even if he presses him with military orders, it is difficult to suppress, fortunately, he is also obedient to the general in the army, but he is too stubborn when he fights; The old third lieutenant was stunned, forty like home, good at grappling, had strong endurance, and could fight a big battle even if he was seriously injured; The old fourth lieutenant Tuwen is also brave and invincible, but this person teaches the other three elder brothers, but he has more resourcefulness and has learned some art of war, and now he is a general in the army, and he is the boss of the three elder brothers.

When the general Tengtengamu saw that these four people took the initiative to ask for battle, he was very happy, and asked them to bring wine and food, treat them well, and let the four of them go to the border with 40,000 troops to stop the enemy. The four of them killed the blood and sacrificed the flag, vowed to kill the Han army to the ground, and then led the army to control the enemy's border.

At this moment, the vanguard army led by Yu Ban and Zhang Yu had just arrived at the Xianbei Realm, seeing that the woods ahead were dense and the heavy rain had just stopped, Yu Ban suggested camping on the spot, and then trying to attack after figuring out the situation. Zhang Pre listened to Yu Ban's words and immediately ordered the army to camp in the same place and not to enter.

Zhang Yuan knew that his younger brother Zhang Yu was more impulsive, so he specially told him before sending troops that he must obey Yu Ban's command and not act rashly without permission. Zhang Pre is also very impressed by Yu Ban, he and Yu Ban have fought many times in the school field, all of which are indistinguishable from victory or defeat, and Yu Ban is skilled in archery and horses, and knows the art of war, and will lead troops to set up formations, so Zhang Pre still admires Yu Ban very much, this time, Yu Ban is the right vanguard and the leader of the general, and Zhang Pre is just a left vanguard, but he doesn't feel anything at all, and he is very respectful of Ban.

When Yu Ban sent out the troops, Zu Zhao also specially explained that although Zhang Yu was brave, he was more reckless, so Yu Ban should be more controllable in the march, so as not to let his temper come up and break things, the defeat of the war is small, but the loss of his life is big. Zhang Pre was a general who followed him from the beginning, and now he has a deep relationship, and he doesn't want Zhang Pre to have an accident. Yu Ban naturally knew that he was also grateful for Zu Zhao's trust in him and his expectations, and he was also cautious along the way, not daring to move forward rashly.

Now after setting up camp here, Yu Ban personally led his soldiers to explore the terrain, while leaving Zhang Pre to guard the camp. Yu Ban led a group of attendants into the mountains and forests, and found a Xianbei person who knew Chinese as a guide, and inspected the nearby terrain in detail. The terrain of this generation of Zhilu Dao is very complicated, and there are many natural traps in it, if you rush into the army, I am afraid that you will encounter accidents. However, the specific places where they are trapped, the guide has always said about it, and Yu Ban has heard about it, so that the cartographer can record this information on the map one by one for later use.

After some investigation, he slowly returned to the army. Just returned to the camp tent, but there was no Zhang Pre, under a question, it turned out that there were a few sika deer just now broke into the camp, Zhang Prelude saw it, an arrow killed one, a shot and a dart killed one, provoked the sergeants to shout loudly. Seeing that there was still a herd of sika deer escaping into the forest, Zhang saw that it was still early, so he stepped on his mount and went hunting with a light cavalry.

Yu Banyan was shocked, there are natural traps everywhere in this vicinity, there are natural big holes that I don't know how to form, the holes are bottomless, the small ones are one or two meters wide and the big ones are seventy or eighty meters wide, but due to the vegetation cover of decades or even hundreds of years, it is very difficult to see clearly, and only people who are very familiar with the terrain of this generation know where those big holes are.

The most important thing is that there are thousands of years of dead branches and dead leaves in the forest, roaring up to thirty or forty meters, the leaves below are rotten, forming some hollows, but the thick branches below are not all rotten, and when there are many people, they fall down, like entering a hunting pit, there is no return, this is equivalent to a swamp in general, it is very terrifying, even the locals are cautious, only dare to go to a certain safe place, and do not dare to run in the forest.

Knowing that Zhang Pre went hunting, Yu Ban felt a little uneasy in his heart, and it was not appropriate to send someone to find it, but Zhang Pre didn't find it, but the person sent was missing. In the end, Yu Ban could only let the letter soldiers carry the war drums and horns, go up the mountain and send a withdrawal signal, so that Zhang Zheng could withdraw.

Let's say that after Zhang Zhulu saw a group of sika deer, he suddenly wanted to hunt, so he went with a group of forty or fifty close guards. A group of people chased the sika deer into the forest, and after chasing for a short time, they disappeared from the sika deer in front. They didn't know that the group of sika deer had all fallen into a huge pit in front of them during the escape, but now the pit was still covered with leaves, and they still couldn't see it.

Zhang Yu circled there for a while with his foot soldiers, and finally chose to pursue in another direction, but did not choose to continue to move forward, so he picked up a small life and did not fall into the giant pit. When he didn't walk for a while, he saw a black bear in front of him foraging, Zhang was overjoyed, and took an arrow and drew a bow to swish directly at the black bear three times in a row, and the black bear was not in a hurry to dodge, and all three arrows were hit. However, this black bear has rough skin and thick flesh, and it did not cause any harm to Zhang Pre's three arrows, but only provoked the big bear on the contrary, and the beast was not afraid of the forty or fifty enemies in front of him, but roared, waving a heavy bear paw and attacking Zhang Pre and the others.

Zhang Pre and the others' mounts heard the roar of the black bear, they were all shocked, spun in place, kicked around, and finally overturned many people, and Zhang Pre also wasted the strength of the two tigers, only to barely control the mount, but the mount was frightened, can not attack normally, seeing the black bear rushing up, Zhang Pre immediately dismounted, ordered the soldiers to fire bows and arrows.

The soldiers received the order and immediately opened their lineup to shoot arrows at the black bear. The black bear was not afraid, and rushed at it with feathered arrows like a heavy rain. Seeing that the feather arrows couldn't resist this guy at all, Zhang Yu ordered everyone to retreat, and each of them hid behind a tree and shot their own arrows.

Although the black bear was full of arrows and shed a lot of blood, it didn't hurt its roots, so it kept rushing left and right, wanting to shoot some people to death, but these people brought by Zhang Pre were all experienced in the military, and they were trained by Feng Luoxue, and they had a very set of fighting alone in the rivers and lakes, and later they were trained by Chen Youzhi, and they also had a set of coordinated operations.

The black bear rushed around for a while but could not succeed, and then the injury gradually worsened, bleeding too much, and gradually lost some physical strength, and finally chose to flee. Everyone was playful, and as Zhang Yu kept chasing the black bear, he didn't shoot it to death, but kept aiming at the non-lethal parts to shoot it.

The bear suffered pain and ran away while roaring, Zhang Yu led the soldiers to pursue behind, and after chasing for a short time, suddenly the black bear in front was gone, only to hear a mournful roar from the ground, the sound went underground all the way, and finally disappeared into the ground.

Zhang Yu and the soldiers were shocked, looked at each other, and walked over very cautiously, only to see a small black hole in front of them, covered with some leaves, the big black bear disappeared here and was hungry, one of the soldiers rushed up first, flicked the bow in his hand, did not think that he would not have time to exert force, his feet slipped and fell.

Just when he was about to disappear, suddenly someone grabbed him by the collar, and it turned out that Zhang Yu saw that something was wrong, and immediately jumped up in one step, and caught the soldier in the lightning. But though he caught it, he slipped and slipped into the pit. In the thrill, the soldiers behind rushed to catch him.

Zhang Yu said loudly: "Be careful of your step, this is a trap, pulling each other backwards." After receiving Zhang Yu's order, the soldiers pulled one by one, and the last few people clung to a big tree to ensure that it would not fall. After some struggle, he finally pulled out the four or five people who had fallen into the hole, including Zhang Yu.

Everyone looked at each other with palpitations, and they all sighed, and almost fell into the hole. "Thank you for your life-saving grace." The soldier immediately saluted Zhang.

Zhang Yu waved his hand and said, "What the hell is this, is this a trap set by hunters?" It almost hurt us. ”

There was a soldier who was nine feet long, very tall, and he looked at it from a distance, and saw that the hole was so dark that he could not see anything clearly, and said, "I don't think it is a trap set up by the hunters, but it looks like a natural hole." ”

When Zhang Yu heard this, he was even more curious in his heart, how could there be such a deep pit in this flat ground, he was really curious, and when he fell into it before, he really couldn't see the bottom, and at that time, the soldier's cry went down, as if he had directly passed through hell.

"Could it be that this is a ghost cave that has passed through hell?" A soldier swallowed and said.

Zhang Yu immediately reproached: "Hugh is talking nonsense, how can there be any ghost holes." This place is too thrilling, I don't know how many caves like this, I have to inform General Yu Ban when I go back, if such a place is used by the enemy, then our march will be affected. ”

"General, will we go now? There's something weird about this place. A soldier said.

Zhang Yu shook his head and said, "We have to see what this is first, and then go back and give an explanation to General Yu Ban." When I sent out the army, my brother told him to take a good look at me, and if he didn't bring back a little useful information to General Yu Ban this time, he would deliberately blame us for not staying well in the barracks. As he spoke, he brushed away the thick dead branches and leaves on the ground with his hand, and after making sure that it was safe, he approached the cave step by step.

When the soldiers saw it, they all followed the example of Zu Zhao, brushed aside the leaves on the ground, and advanced towards the cave step by step, and finally arrived at the entrance of the cave. Some superstitious people firmly believe that this is a ghost cave and suggest that Zhang pre-leave quickly, but Zhang Pre-'s bull temper came up and said that he wanted to go down to have a look.

This frightened all the soldiers, this strange cave, how can you go in and have a look, it is all to persuade him to leave here quickly. But Zhang Yu just disagreed, he said that he just went down to see, there would be no big deal, as long as the rope was tied to his body, and the soldiers would slowly put him down.

In the end, everyone couldn't resist Zhang Pre, so they could only take out the ropes on their bodies one after another, connect them, and be hundreds of meters long, and then let Zhang Pre go down, while they pulled the rope outside. Zhang Yu said: "If something happens, I will pull the rope violently, and then you will pull me up." ”

Everyone nodded in agreement, telling him to be careful, they were worried that something would happen to Zhang Yu, but no one dared to say that, they could only say that they should be careful, and once they found that something was wrong, they would immediately pull the rope, and then they would pull him up.

After Zhang Yu went down, he felt that there was nothing at first, but after going down forty or fifty meters, he found that it was still dark below, so he asked the soldiers to continue to put him down, and he was bound to go down to see what the situation was. Looking up, I saw a ray of light coming down, and there were soldiers around the entrance of the cave, all cautiously looking inside.

When descending to a depth of 100 meters, Zhang found that his breathing was a little difficult, and his chest was also very sad, and the light was too dark to see anything clearly. He shook his head vigorously, and found that he was getting more and more difficult to breathe, his head was dizzy, and his chest seemed to be full of air, and as if he was not full of qi, and in general it was very uncomfortable, so he pulled the rope violently, and let people pull him up.

When the soldiers saw that the rope was being pulled violently, they immediately pulled Zhang Pre up with concerted efforts and walked out of the hole, and Zhang Pre felt a lot more comfortable. The soldiers hurriedly asked about the situation inside, and Zhang said that it was too dark underground to see clearly. But he still didn't give up, and ordered someone to light a torch to go in and have a look. The soldier tried to persuade him for a while, but he still couldn't persuade him, and finally lit a torch.

When the torch was lit, he heard the horn of withdrawal, and it was very urgent. "Good and decent, why did you order the withdrawal of the troops?" Zhang asked suspiciously.

"Could it be that a thief is coming, so the order is to withdraw the army?" Some soldiers said.

"Oh no, we have to get back to support as soon as possible." Zhang Yu said, immediately threw the torch into the hole, and hurried out of there with the soldiers. Who knew that they hadn't run a hundred meters yet, when they suddenly heard a booming sound behind them, followed by a wave of shaking mountains, and the earth trembled violently.

Zhang Pre and the others turned their heads to take a look, only to see the fire in the cave rising into the sky, the flame went straight to more than 100 zhang, there were flames jumping up behind it, the sound of explosions was constantly coming, the dead branches and leaves at the entrance of the cave had also been burned, driven by the strong wind, the flames jumped around, and quickly burned in the forest.

Zhang Yu and the others' faces changed suddenly, they were very surprised, and at the same time they were surprised that they should not die, if they went in with torches, they were afraid that they would have been burned to death by now. Seeing a burst of fire, everyone hurried out of there and ran to the barracks. Just a few hundred meters away, suddenly a pair of soldiers and horses in front of me rushed towards this side in a bustling manner.

Zhang heard this, and he didn't know who was coming, so he immediately asked the soldiers to cover up. After a while, a team of men and horses appeared in front of him, the first general, but it was Yu Ban, he was pale, and he was running towards this side with the army, and there were four or five horses leading the way in front, and there were no people or things on horseback.

Seeing that Yu Ban was coming, Zhang Yu flashed out with the soldiers. When Yu Ban saw Zhang Yu, he finally breathed a sigh of relief, looked at the sky-high fire in front of him, and asked, "What the hell is going on?" ”

Zhang pre-said: "There is a deep pit ahead, and after we threw the torch into it, there was an explosion, and I don't know what was in the tunnel." ”

Yu Ban looked at it for a while and said, "It's okay if you don't have anything to do, get out of here quickly, the fire has already burned." ”
