Hu Cai, Li Le and others ran back to Baibo Valley, they gathered the displaced people from all over the world, and the momentum was revived, but they gradually found that they had recruited too many displaced people, and the grain cultivated in the valley was simply not enough to eat, so they selected 50,000 strong men from more than 200,000 people, and encouraged Huchuquan to gather in Pingyang City, not far from Baibo Valley, to do a big deal with them.

After Hu Cai joined forces with Huchuquan, he borrowed from Zhang Yan, who was also a member of the Yellow Turban Yu Party, crossed Taihang, went straight to Hanoi, and ambushed above a section of the river, waiting for Wei Yan's army to go down the river.

Hu Cai and Hu Chuquan thought that their 60,000 horses would be able to easily defeat Wei Yan's men and horses, but unexpectedly, Wei Yan first ambushed the front of the Baibo army with crossbowmen, and then beheaded the generals to capture the flag, frustrating their morale, and then flanked the two phases, completely defeating the combined forces of Hu Cai and Hu Chuquan, Hu Cai's Qu Shuai was killed and wounded, and only Hu Cai fled back to Baibo Valley with two arrow wounds to recuperate.

It's only been half a month, Hu Cai's arrow wound has not healed, and the news that the Baibo army was defeated by Wei Yan's army has spread, and there are very few displaced people who have come to Baibo Valley to defect in this half month, so there are only 110,000 old and weak soldiers in Baibo Valley, plus more than 30,000 Hun old and weak soldiers entrusted to him by Liu Bao, among the 150,000 people, less than 20,000 can really be put out to fight.

But Hu Cai was not afraid, he knew very well the danger of the passes at both ends of the river valley, not to mention putting seven or eight thousand men and horses, even if he put seven or eight hundred men and horses, he was not afraid of the attack of Wei Yan's tens of thousands of horses, so he hid in the depths of the Baibo Valley and took the elixir.

Wei Yan came out to meet the Hun cavalry this time, and went into battle lightly, without carrying a thunderbolt.

When he came to the end of the Baibo Valley, he first had to cross a large dense forest that covered the sky and the sun, Wei Yan first sent a scout battalion to carefully search this dense forest about two or three miles long, and found no ambush, so he dispatched all his men and horses to continue to advance into the Baibo Valley.

After that dense forest, I saw an extremely dangerous pass, it was the original vast Fenshui old river channel suddenly narrowed, as if a gap was split between the cliffs on both sides, the widest part of this gap was only more than two zhang, the bottom of the river was built with many huge bluestones, the bluestone steps more than two zhang high were more than three feet thick and one zhang high above the wooden gate, above the wooden gate was the arched city tower made of bluestone, the city tower was connected with the cliffs on both sides, and the cliffs and the city tower were stationed above the white wave elite soldiers who were on full guard.

Wei Yan looked at it for a while, and understood why the Baibo army could survive for so long and not be wiped out by the official army, thanks to the terrain of this Baibo Valley, the danger of this pass lies in its narrowness and towering, if the official army attacked, it must climb up the bluestone steps from the bottom of the river, and then climb over the city wall built with the cliff as the foundation stone, and the pass is so narrow that it can only put down four or five hundred people to attack at a time, and the Baibo army on the city tower and cliff wall is seven or eight thousand people, so it seems that Unless you smash it with a thunderbolt, you can't take it down at all according to ordinary siege methods such as ladder rushing.

Wei Yan asked Xu Shu in a low voice: "Can you inform the fine workers in the valley to take the opportunity to open the city gate?" ”

Xu Shu shook his head: "These fine works were all added later, and they were not trusted by Hu Cai, and they were all placed in the depths of the Baibo Valley, and they were not allowed to approach the valley mouth." ”

Wei Yan asked in surprise, "Then how did their information come out?" ”

"Hu Cai wants to raise 150,000 people, and the cultivation in the Optics Valley is far from satisfying, so he takes turns to send people out of the valley to loot grain. Xu Shu also looked at the pass of Baibo Valley with great regret: "They said in the intelligence that this pass is dangerous, I didn't think so at the time, and now it seems that they really underestimate this magical pass." ”

Wei Yan pointed to the top of the White Wave Valley: "Can we rush down from above?" ”

Xu Shu still shook his head: "There are steep cliffs above the river valley, and the walls are thousands of feet, which is difficult to climb up and climb. ”

At this point, it seemed that he was at a loss, but Wei Yan did not have the slightest anxiety on his face, but smiled faintly: "Since it is so easy to defend and difficult to attack, let's attack slowly!" ”

Wei Yan then ordered the trees on the side of the valley to be cut down, creating improvised catapults, and threw stones at the pass one by one, except for the loud sound of stones hitting the cliff walls and wooden gates, these dozens of catapults did not have any effect on the Baibo Valley Pass.

Wei Yan ordered people to make nearly 100 big drums, and hundreds of drummers kept beating them.

Wei Yan then ordered 10,000 auxiliary soldiers to shout in unison: "Kill!" "Rush!" "It's about to be captured!" Words like that.

After making these arrangements, Wei Yan disappeared into the dense forest on the side of the river valley with 30,000 soldiers.

A few hours later, Liu Bao and Guo Yuan appeared on the side of the valley with the exhausted 50,000 Hun cavalry, they heard the roaring stone throwing, rumbling drums, and earth-shaking shouts at the Baibo Pass from a distance, they looked at each other and smiled: "The Wei army is attacking the Baibo Pass, let them continue to attack, anyway, the Baibo Pass is very dangerous, let's rest now!" ”

Guo Yuan's invincible Yuan army passed through the Tongtian Mountain to Baibo Valley on the way to attack and harass, and it has been sharply reduced from 10,000 to more than 4,000, so it is difficult for such a few people to ensure their own safety, so he began to be polite to Liu Bao, and there was a smile on his face.

The 10,000 auxiliary soldiers of the Wei army shouted for several hours, they were all a little tired, their shouts became weaker and weaker, and the soldiers who operated the catapults and beat the drums also fell limply, too lazy to exert their strength, and the sound of drums and stones was much weaker.

Liu Bao and Guo Yuan looked at each other again and smiled: "It seems that the Wei army is not attacking the city well and is tired, now it's time for us to play, let them relax completely!" ”

Liu Bao waved the scepter that symbolized the power of his Xiongnu Zuoxian King, and shouted: "Revive the Xiongnu, success or failure in this move!" Come on! ”

The 50,000 Hun cavalry held their breath on the way, unable to vent, this time finally found a person to vent, they were like a pack of hungry wolves, pounced on the dense forest, as long as through this dense forest, they could attack the Baibo Pass and the exhausted Wei army in one fell swoop.

This dense forest, growing on both sides of the old Fenshui River Valley, is very thick, it can be said to cover the sky and the sun, and only the dry riverbed in the middle can be used by cavalry.

Guo Yuan was frightened by several ambushes by the Wei army, and when Liu Bao summoned the Hun cavalry to prepare to ride into the old riverbed in the middle of the dense forest, he hurriedly stopped Liu Bao: "King Zuoxian, don't enter the forest!" ”
