Don't move, this child bride is not easy to mess with.

Civil servants in charge of the army pay more attention to military law. Although Xie Chengan has martial arts skills, he is still a civil servant at heart, so naturally he highly respects these three military orders.

There are military orders to restrict it, whether it is a general or a soldier, if you retreat, you will die.

With no way out, there was only one thought: Kill, kill, kill!

However, after killing hundreds of enemy troops in a surprise attack, Tan Ma came to thank Chengan. There were 20,000 cavalry ten miles away from the pass, and they reached the pass within half an hour.

In such a short period of time, it was too late to completely annihilate the enemy forces in the pass.

How to do?

Xie Chengan and Su Mulan looked at each other and got the same idea from each other's expressions: Burn Bauhinia Pass!

There was no time to think about it, so Xie Chengan immediately ordered Zhao Jingzi to stop attacking the city wall and just find dry firewood on the spot and set fire to it! He also sent people to inform the other seven centurions not to engage in street fighting, and also set fires on the spot.

Now, the fire oil tank that Su Mulan had insisted on bringing became the best thing to start the fire.

Originally, these soldiers were not willing to bring this thing, because each of them had a full set of thunderbolts, waist knives, military rations and other items and the burden was heavy.

Poison fire mines, wind dust cannons, and fierce fire oil tanks were also issued. It was too troublesome to have them scattered and scattered.

As for setting fire, it is generally useless. There are always people inside the city gates. Wouldn’t they all be burned to death if they set fire to them?

However, Zijin Pass was different at this time. The imperial army was defeated a month and a half ago, and the few merchants and common people in the pass had already fled into the capital.

This is the main premise for burning Bauhinia Pass.

Just do it, and within a moment, dozens of fires broke out in Zijing Pass, and three of the four gates burst into flames. Su Mulan also had people fire more than a hundred fire and flying sand cannons at each of the three city gates.

Then there was a fire, and there was smoke and poisonous gas that sealed the door. None of the defenders within the pass would be able to escape, and the enemy cavalry, which had already marched thirty miles toward the capital, would not be able to cross the pass for reinforcements.

After all the teams responsible for setting the fire withdrew, the last door also set a fire. Then Xie Chengan sent Zhao Jingzi to lure the enemy and guide the 20,000 cavalry ten miles away into a canyon not far outside the pass.

Before leaving Zijingguan, Xie Chengan originally planned to use the woods on the mountain to ambush the enemy. When I came out of the customs, I almost fell off my horse in anger.

It turns out that the mountains and forests outside the pass are sparse and not suitable for an ambush at all. There are quite a few tree stumps one foot high, and they look quite old.

No need to guess at this either. Relying on the mountain and eating the mountain, this must have been done by the officers and soldiers of Qianhu who were originally stationed at Zijingguan. These woods were cut down, part of which was supposed to be used to build forts, and most of which were sold to timber merchants.

This is not surprising. Hundreds of the capital's city defense cannons were sold by the eunuchs and exchanged them for money to put in their own pockets. As for the cannon on the city wall, it turned out to be a fake cannon made of wood!

Master Yu discovered this when he was inspecting the city defense. He was so angry that his eyes turned black and he wanted to kill someone. It's just that the eunuch and the Supreme Emperor were captured by the enemy a long time ago, so we can only give up for the time being.

There are no mountains and forests outside the pass, but the detective horse reported that there is a canyon nearby, which is suitable for an ambush.

It's just that the enemy soldiers are not fools, and they will be fooled if you provoke them.

But Zhao Jingzi has experience in this matter. When he was a member of Qianhu, he wiped out countless mountain bandits and water bandits, and gained two experiences: either there is enough profit, or there is enough hatred.

Su Mulan suggested that he just use them all. All the gold and silver belongings carried by the whole camp were handed over to Zhao Jingzi's 300 men, and they scattered them along the way to attract the enemy's cavalry when they fled.

The entire battalion's thunder cannons were also given to these three hundred people. A single volley could fire five thousand blasts, not to mention killing five thousand cavalry, but at least it would not be a problem to kill one or two thousand people.

Each person throws three more poisonous fire thunders to ensure that the 20,000 riders will be beaten to death!

As expected, Xie Chengan and Su Mulan had just laid ambush in the canyon when they heard thousands of horses galloping at the entrance of the canyon!

Zhao Jingzi's three hundred cavalry escaped in a very embarrassed manner, but it wasn't because of their realistic acting skills. First, the Thunder Gun has a short range. In order to kill more enemy cavalry, they were bitten during the battle.

Second, the enemy's horses were strong and strong, and one man and two horses were chasing him. Fortunately, the canyon was not far away, so they persisted and ran to the ambush site.

The canyon was winding and winding, with a swamp in the middle. Neither side was running very fast. After another half an hour, Zhao Jingzi released several Divine Fire Flying Crows.

This was a signal agreed upon in advance, indicating that Zhao Jingzi had arrived at the exit of the canyon.

The Divine Fire Flying Crow is actually a large kite, half a meter long. It just uses gunpowder to help it fly, and its range is about three to five hundred meters.

The flying crow of divine fire landed in the group of pursuers and immediately blasted the enemy cavalry into confusion. Although its lethality was limited, this thing mainly started a fire, igniting the dead wood and fire oil placed nearby.

More than ten thousand riders had already entered the canyon. Although only half of them had arrived, Xie Chengan had no choice but to order an ambush. Use fierce fire oil and ten thousand fire flying sand cannons to cut off the entrance to the canyon.

There are cliffs on both sides of the canyon, and the entrances and exits at both ends are blocked. It is autumn at this time, and the ground is full of dead branches and leaves, which are excellent fuel. These more than 10,000 riders can only wait to die inside.

Thousands of riders outside the valley were suddenly blocked by fire. Knowing that they had been tricked, they wanted to retreat.

However, the mountain road was narrow, and the rear team, unaware of the situation, still pushed their horses forward with all their strength. For a while, people outside the valley were on their backs and their horses were on their backs, making a mess.

"Kill!" Xie Chengan shouted sharply, and the seven hundred horsemen charged like fierce tigers out of a trap.

Because the thunderbolts had previously been concentrated on Zhao Jingzi's 300 men, now the charge cavalry could only hold a knife in one hand and throw wind and dust thunder with the other to help.

Don't dare to throw away the poisonous fire thunder. There is fire oil inside that will ignite when it comes into contact with anything and cannot be extinguished by water, not to mention the poisonous gas. This thing can make no distinction between the enemy and ourselves. If the two armies fight, it will easily hurt one's own side.

The enemy cavalry was already in chaos, but these 700 cavalry rushed into the formation with red eyes, and smoke bombs were fired from time to time. It was unknown how many enemy troops were ambushing them, and they suddenly had no fighting spirit, and the front team ran back desperately.

Everyone in the sentry camp had branches hanging from their tails. As their horses galloped, dust flew all over the sky. It was as if tens of thousands of horses were rolling towards them, and the enemy's horsemen suddenly collapsed.

In order to survive, the enemy's front line even picked up knives to attack their fellow tribesmen. Hundreds more people died, and the center collapsed.

Xie Chengan led the team, accurately controlling the distance between the defeated troops and driving them behind. When he saw more than ten people trying to form a team, he threw thunderbolts to disperse them.

If they were too close, there were only 700 of them in total, how many people could they kill? The enemy cavalry was forced to fight tooth and nail, which in turn increased our own casualties.

If you are too far away, the enemy cavalry will have time to reorganize their formation, and it will not be easy to defeat them again. You may even find that the pursuers only have a few hundred people.

Only by controlling the distance, making the enemy's cavalry unable to counterattack, and urging the broken army to attack the formation can we remain invincible. This is the famous reverse-rolling bead curtain in cavalry tactics!

Although these foreign cavalry are extremely powerful individually, their ability to coordinate operations in small units is poor. After all, they are just herdsmen from countless small tribes. How can they have the discipline of Han people?

Xie Chengan looked at the entire battlefield and couldn't help but breathe a sigh of relief.

This battle - won! Big win!
