Yuan Taizuo naturally will not sit idly by and let others harass and sneak attack. Both Goguryeo armies sent a large number of spies to search the surrounding thirty miles, but these spies won fewer victories and more defeats in the face of the spies and special combat teams sent by Shen Guo'er, and suffered heavy casualties.

In this way, there are delays and attacks from mines during the day. At night, no matter how tightly defended the Goguryeo army was and how many sentries were dispatched, there were always people in the special combat team who could sneak into the Goguryeo camp and set fire to it and blow up the camp with gunpowder, not to mention how many enemies were killed, and the Goguryeo army could not sleep well every night, and the result was already very serious.

In the past few days, the two armies of Goguryeo, from Yuan Taizuo to every soldier below, are already frightened birds, one by one exhausted, not to mention that they can't go fast the next day, and the army's heart is shaken greatly, because the morale of the fleeing drum is also falling rapidly.

Yuan Taizuo naturally knew the seriousness of the problem, but he couldn't find a solution to the problem for a while.

In the Yuan Taizuo camp, discussions are underway for the next move.

"Wang Junlin is extremely treacherous, and he even sent a small number of elite masters to constantly sneak attack us, and he has a terrifying weapon such as gunpowder in his hand, which has no way to solve it."

"But what if we don't solve it, do we want to let the Sui people rob us of all the wealth in the capital, kill our people, and then escape calmly?"

"Our forces are far above the troops that Wang Junlin attacked Pyongyang, so they are very afraid of being caught up by us. And it is precisely because of this that we must catch up with them, and as long as we catch up with them, we will definitely be able to kill them all. ”

"I'm afraid that when we are most sleepy and unable to chase the enemy, Wang Junlin's army will suddenly turn around and attack us secretly, and at that time, how much strength do we have to fight, even if we are four or five times as many as them, we can really defeat them."

The generals were arguing, and then a messenger came in and whispered something to Yuan Taizuo, who had been gloomy and did not speak. Yuan Taizuo perked up and shouted, "Okay, don't make any noise." ”

The generals immediately stopped and looked at Yuan Taizuo, who took a deep breath and said, "Benxiang received a very important news just now. Wang Junlin's main force can't go fast at all because he has more than a thousand carts of wealth, and now there is Sanyang Valley hidden, which is only more than a hundred miles away from us. ”

When the generals heard this, their eyes suddenly lit up, and they were all overjoyed.

Wang Junlin and his entourage camped.

After Shen Guo'er read the information sent by Feiying, she smiled slightly and came to see Wang Junlin with a happy face.

"My lord, I just got the news that Yuan Taizuo has taken the bait."

"Very good, send a letter to the armies of Silla and Baekje, and ask them to go to Samyang Valley to meet their divisions and kill Yuan Taizuo according to the plan."

…………

…………

When Yuan Taizuo led a large army to kill the king of Sanyang Valley and his party, 30,000 cavalry each of Silla and Baekje received the Flying Eagle message arranged in advance by Shen Guo'er almost at the same time. Then he led his 30,000 horses to Sanyang Valley.

As soon as they entered the Sanyang Valley, there was a report from the rear, saying that they found the Sui army at the entrance of the valley behind them, blocking their retreat, and the flag fluttering on the other party's head had a big king character written on it, and the number was about 10,000.

This is naturally the 10,000 cavalry led by Wang Junlin, whom they want to pursue.

Yuan Taizuo suddenly became suspicious, they had already entered the valley, and with the shrewdness of Wang Junlin, they knew in advance that this was nothing, but the other party did not escape, and appeared behind them strangely, and blocked their retreat.

What is the situation, Yuan Taizuo faintly felt that something was wrong, and when he looked at the terrain in this valley again, his face suddenly changed.

The valley was mountained on both sides, and although it was not high, the slope was enough for the infantry to crawl, but it was difficult for the cavalry to pass through. And the depths of the valley are also backed by mountains. The only exit was from the valley they had just entered.

A general took a deep breath and said solemnly: "Wang Junlin has a great appetite, although we are tired, we still have the advantage in numbers, and this valley mouth is a hundred zhang, which is enough to reflect our numerical advantage." ”

"I'm afraid it's not that simple." Yuan Taizuo shook his head, his expression was still full of worry, he and Wang Junlin had a lot of confrontations, he had never taken advantage of it, and even suffered a big loss at the hands of Wang Junlin every time.

As soon as Yuan Taizuo's words fell, a series of explosions like thunder suddenly sounded from the left half of the valley mouth. I don't know how many explosives were buried in the ground, and it resounded for more than ten breaths, giving people a faint feeling of changing the color of heaven and earth. Even though the horses on both sides were hundreds of feet apart, and there were things stuffed in their ears, they still caused a lot of commotion, but they were quickly pacified by the cavalry.

After the explosion, half of the 100 zhang valley became a ravine one zhang deep and two or three zhang wide, leaving only the other half about 50 zhang wide for the cavalry to pass through.

Yuan Taizuo and the generals suddenly changed their faces.

"Hmph, what can we do even if the valley mouth narrows, I don't believe that our more than 40,000 people can't beat them 10,000." A general gritted his teeth and said,

At this moment, however, another spy came to report that two more cavalry armies of 30,000 men were found in the distance.

Yuan Taizuo and the generals suddenly became extremely pale.

"Damn, it's the Silla and Baekje people." Yuan Taizuo understood everything in an instant, and they fell for Wang Junlin's tricks again.

Taking a deep breath, Yuan Taizuo turned his head and ordered loudly: "Inform the whole army, the Sui army that attacked our capital was caught up by us, for the sake of honor, for military merit, to kill all the enemies, the thousand carts of wealth they stole from Pyongyang City, the prime minister took half of it and distributed it to the whole army, and he will never break his promise." ”

The Goguryeo army covered the mountains and fields in the valley.

The allied forces of the Sui Kingdom, the Silla Kingdom, and the Baekje Kingdom totaled about 70,000 people, with 10,000 cavalry of the Sui Dynasty in the middle, and 30,000 cavalry each of the Silla and Baekje countries on both sides.

The 70,000 troops all quietly looked at the dark clouds of Goguryeo's cavalry two or three miles away. Everyone stood at their posts in high spirits, and their morale was like a rainbow.

On the slopes on either side of the valley mouth, two stone throwing positions have been built, and behind each position there is a tunnel fortification, in which three hundred gunpowder bags of various types are placed.

Wang Junlin rode in front of the ten thousand armies, and also quietly looked at the Goguryeo cavalry on the opposite side, although the number of people on their side was 20,000 more than the other side, but the cavalry of Silla and Baekje was probably inferior to the Goguryeo cavalry.

However, Wang Junlin was still full of confidence in this battle, because he knew that the physical strength and spirit of the Goguryeo army at this time were too far behind those in their heyday, and the corresponding combat strength would definitely be weakened.
