The messenger of the Western Turkic Republic repeatedly advised him, but Li Xinzhong was also a master who did not see a rabbit or a hawk. If he had not been beaten to the door by the Tang Dynasty, he would not have wanted to compromise with the Western Turkic barbarians.

In the end, the two sides agreed to form an alliance in this hall to fight against the Tang Dynasty. Li Xinzhong handed over the poppy seeds and 50,000 Botian Thunder. He agreed that if Tubo was saved this time, the method of making Botian Thunder would be sent as a follow-up cooperation project.

The Western Turkic envoy returned to report his life, and his face was not so relaxed. In fact, this time, the Western Turkic took advantage of the situation and wanted to do a business without any capital, but did not intend to save Tubo because he could not do the best.

The Western Turks had only 200,000 soldiers, and they could not stop the thunder of the Tang Dynasty. Therefore, the border between the soldiers was all empty words. However, if the secret recipe for the thunder of the sky was not obtained this time, whether it was necessary to turn from virtual to real is a difficult problem for the Western Turks.

After sending off the Western Turkic envoy, Li Xinzhong did not have time to explain much to his younger brother Li Mingxin, because the Tang Dynasty soldiers were very fast, and they were afraid they were attacking continuously all day long and had to make a surprise plan to block them.

Li Xinzhong's eyes were fierce, and he made a secret decision in his heart. He did not send reinforcements because he heard that the Tang Dynasty had magical weapons that could hit twice the distance of a catapult, and the Tang Dynasty thundered countless sky thunders, so it was futile to increase the troops in Tubo in some way.

However, he sent his own confidant team, a team composed of purely the death soldiers of the Li clan of Longxi, and brought all the high-explosive gunpowder to the official road of the Sanli Canyon west of Pibo City.

Three days later, the invincible army of 50,000 people from the Tang Dynasty came to the front of the only official road westward. The plateau was bitter and cold, and Tubo was already sparsely populated, with very few cities, and there was not even a single official road between many cities, which created Tubo's geographical advantage that it was easy to defend and difficult to attack.

This is the case with the Tang Dynasty. It captured half of Tubo, but was blocked by a three-mile-long official road. There was no other path. It was surrounded by dangerous mountains and forests. It was impossible for the Tang Dynasty to open up a new road from other places because of these three-mile lands.

Li Yuanji raised the horse spear in his hand and stopped the entire army. The entire army stopped. The scouts sprinkled out to find out the reality of the place.

When the military strategy is clouded, don’t enter the forest. Be careful when encountering valleys. These places are excellent places for the enemy to ambush and set traps. As a famous general, why didn’t Li Yuanji know to be cautious?

Yuchi Baolin personally led a team of climbing and reconnaissance to climb to the top of the Sanli Canyon. After an hour of investigation, he did not find any ambushing scouts in the army that had sprung twenty miles without any abnormalities.

The mine detector also carefully investigated, and there were no mine traps on the ground.

"Have you ever analyzed this place?" Li Yuanji turned around and summoned Hong Qianli and asked.

Hong Qianli saluted and said, "The terrain here is narrow and long. Although the official road can be equipped with five large vehicles, it is still an excellent place to lie in ambush.

We infer that the enemy cannot avoid ambushing, especially since our journey is too smooth and we will not even see the enemy's reinforcements unless the enemy flees ahead of time."

Cheng Huaimo continued: "Can it be that our crossbows scared them, caught them off guard and dared not set up an ambush?"

"This is unlikely. The reason why the specific enemy does not set up an ambush is unknown. Everything we do is to break the ambush, and now all of them have failed.

If I were the Li brothers, at the very least, I would have to blow up the entire canyon and delay our march, but the current situation is really hard to understand."

Li Yuanji nodded and said, "Even if the enemy has not set up an ambush, we should not be careless at all. We must pass quickly to avoid long nights of dreams."

To be honest, Li Yuanji felt uneasy today. This was caused by the intuition sensitivity of the military generals and masters, but he had sent people to investigate it three times, and there was no movement in these three miles.

"The Grand Marshal, the military division camp suggested that for safety reasons, the Canyon Highlands sent scouts to marches and guards.

And make preparations, and quickly pass the passage through the ants by moving the house, so as to avoid any unknown tricks from the enemy."

Hong Qianli convened the military division camp and finally made an optimization plan. It was not that the Tang people were timid and did not dare to leave openly even though they knew there was no threat. Instead, the Tang Dynasty only had these 50,000 troops able to fight on the plateau, and it was not an exaggeration to be cautious at all.

"Brother Third, let me follow the army to guard the army. I am strong and can deal with it even if I have something to do." Li Yuanba pulled out his peerless sword and spoke.

Li Yuanji was very reluctant to take the risk first, but at this time, the army was in front of the army, and it was really impossible to reject it. After all, the soldiers behind him were also robes, and the general had the responsibility to share the joys and sorrows.

"Okay, the 50,000 troops are divided into fifty teams, and the ants move quickly through the canyon."

With the order of Li Yuanji, the army acted quickly. Li Yuanba immediately held the sword and followed the first thousand-man team all the way through the valley.

"Okay, Brother Third, there is no danger of passing the test smoothly. You can speed up the pace later." Li Yuanba came back quickly and said.

So the 50,000 troops began to advance in a group of rapid formations. What they didn't know was that on the mountain walls on both sides of the valley, about ten meters away from the top, there were actually people hiding, and the two teams of elite dead soldiers sent by Li Xinzhong.

This is Li Xinzhong's vicious plan. Since blowing up the canyon can delay the Tang Dynasty's advance, why not use everything to destroy the 50,000 troops of the Tang Dynasty in one fell swoop. In this way, there is no need to ask for help, the danger of Tubo will naturally be eliminated.

After studying the marchings of the Tang Dynasty, Li Xinzhong knew that he had basically no chance to ambush and hurt people. Finally, he thought of Li Mingxin telling him the story of opening mountains, bombing stones and building roads in the Tang Dynasty. With a sudden inspiration, he stumbling out the stone caves that could hide people. It doesn’t have to be too deep, just hide and safe.

When the Tang army passed through the valley, it detonated the high explosives on both sides of the valley, and destroyed the valley and destroyed the army.

Although two teams of loyal dead soldiers need to be sacrificed, for the sake of Tubo's safety, all sacrifices are worth it.

The captain of the dead soldiers hidden on the mountain wall saw the Tang Dynasty so cautious, and the ants moved? How did they do this? The hatred in my heart was itchy. We were ready to sacrifice our lives for you 50,000 troops. Who knows that you are reluctant to let it go?

After thinking about it, seeing that more and more Tang Dynasty passed, the captain of the Dead Soldier decided to blow up the team that was most threatening to Tubo, not the Sky Thunder Transportation Team, but the Tang Dynasty's crossbow transport team. Those complex things must have caused Tubo to suffer a great loss this time. As long as it is destroyed and the 50,000 troops were cut off in half, so that the head and tail could not be taken into account, the danger of Tubo could be solved.

After figuring it out, the man watched the crossbow transport team enter the valley and arrive at the ambush, and first ignited the high-explosive gunpowder around him.

Boom! A shocking sound caused the earth to shake, rocks rolling, and then hundreds of loud noises. Other dead soldiers saw the captain's cigarette light signal and followed them to ignite.

"No, damn it, fourth brother!" Li Yuanji exclaimed. As the general of the guard, Li Yuanba was guarding him every time the team walked through. With this master, the soldiers could feel more secure.

Yuchi Jingde, who was patrolling on the top of the mountain, saw that there was a faint blue smoke coming out of the mountain wall. He was shocked and was about to warn him, but the sound of shouting was not heard, and the mountain wall had already exploded.
