The soldiers maintained a high degree of vigilance, waiting with bated breath at their respective posts for the enemy to come to sneak attack, but they never saw any movement outside the city, and the soldiers were also very puzzled, not knowing where the enemy would come from to sneak attack, would it fall from the sky?

Around the ugly hour, the dozen or so soldiers who looked like earth fans gathered under the castle tower suddenly moved, only to see them all bent down and look at the two places that had been circled by heaven.

I saw that the soil in the circle suddenly shook, and then the ground loosened, and a small hole appeared, and as the dirt fell down, the hole became bigger and bigger, and then a pickaxe tip stretched out from the hole, and kept digging the earth.

It turned out that these were two very long tunnels dug in from outside the city in order to launch a sneak attack from inside the city, and today they were finally dug through the city. As early as ten days ago, Tianci heard a strange sound, and after careful identification, he found that this was the enemy's plan to dig a hole outside the city, wanting to quietly sneak the strange soldiers into the city, and then cooperate with the outside to capture the city in one fell swoop.

After Tianci discovered this situation, he paid attention to the enemy's movements every day, and calculated that it could be dug through this night, and the siege operation must be tonight, so he had already made preparations, arranged in advance to break up the enemy's attack, and by the way completed the capture of the enemy's prisoners.

Finally, the entrance of the cave grew bigger and bigger, and when there was a pot, he poked his head out of the hole, and before the man could see the situation clearly, two people who were ambushed at the entrance of the cave lifted him out of the hole, and then several people gagged him, tied him firmly, and pulled him down.

The other two soldiers stepped forward to dig the hole further wider, and then shouted inside in the Tufan language, and after a while another Tufan soldier came out of the hole, and then the Tufan soldier who was pretending to be outside the cave asked him to wait in place, and when the next person also came out, the pretended Tufan soldier motioned for them to follow him and walked towards the city.

The Tufan soldiers who came out of the cave one after another lined up with the people in front of them and quietly touched the city. The same is true for the other hole.

After almost one hundred and thirty people had been drilled out of each of the two holes, no one came out again. These more than 200 people followed the Tufan soldiers who led the team to the city, and after they left, about 20 Dafeng soldiers came forward to backfill the two holes with earth and stones, and sealed them.

The two "Tufan" soldiers who led the way in front led a group of Tufan soldiers to the repaired wooden fence in the cavalry camp, and signaled everyone to enter quietly, and then ambushed in the same place, and then the two quietly withdrew, closed and locked the wooden fence door.

As soon as the wooden fence door was closed, more than 300 Dafeng soldiers rushed out from both sides, surrounding the wooden fence, and one hundred of them archers ignited the arrows, pointing directly at the surrounding Tufan soldiers.

At this time, several soldiers shouted to the besieging Tufan soldiers in the circle in the Central Plains and Tufan languages: "You have been surrounded, do not resist, otherwise our army will fire a volley of rockets, and you and others will be covered with oil and flint, and they will be burned to ashes in a moment after ignition." He also said: "Please ask the person in charge of the leader to come out immediately to present his case, the commander of our army is merciful and generous, and he can give you a way out as appropriate." ”

At this time, there was a commotion in the circle, and those Tufan soldiers who had entered the city from the hole found that they had been captured, and in addition to the short knives for self-defense, they were full of flint and sulfur and other things that were ready to set fire to the city. Faced with this situation, everyone had no choice but to give up resistance and obediently surrender.

After a while, several soldiers escorted the two leaders of the Tufan soldiers who had infiltrated the city to Tianci, and handed over a signal arrow that had been seized from them. After a simple inquiry, Tianci asked the two to be escorted down.

"Someone, give the order, open the door and light the fire immediately!"

After a while, the north gate was opened, and the fifteen fires above and below the city tower were also lit, and suddenly a raging fire broke out in the city, reflecting the night sky red.

At this time, Tianci ignited the signal arrow in his hand and shot it into the sky. The arrow flew into the sky, and a moment later, a firework burst into the night sky.

Immediately, outside the city, which was silent just now, a black crowd rushed towards the city, rushing to the front of more than 3,000 cavalry, and behind were tens of thousands of soldiers armed with spears and short knives, surging up like a tide in the silent darkness.

After the leading cavalry just stepped on the firewood and grass belt arranged outside the city in advance, a cannon sounded at the head of the city, and the archers in ambush on the city wall immediately shot the ignited rockets to the firewood and grass belt outside the city.

Less than a hundred cavalrymen rushed through the wall of fire and were immediately attacked by a rain of arrows from the walls, and most of the cavalry were shot off their horses.

The remaining cavalry tried to turn around and retreat, but found that the retreat had been blocked by fire, so they had to risk their lives to rush forward, and finally more than thirty cavalry rushed into the open city gate.

The Tufan cavalry, who had rushed into the city gates, found that the city was relatively empty, and when they saw no enemy obstruction, they rode their horses and rushed forward.

At this time, two cannons were suddenly heard in the city, and seven or eight triphorse ropes were immediately bounced from the ground, and the more than 30 cavalrymen who had just rushed into the city were overturned to the ground, and suddenly a burst of people howled and neighed, and they rolled in pain on the ground.

After hearing the second cannon order, Wan Chengpeng immediately led the soldiers who were ambushed by the city gate to rush up and capture these dozens of cavalry one by one without much effort.

At the same time, Tianci had already led the other soldiers of the cavalry battalion to rush out of the city gate, lined up under the outer walls of the city, and waited for the battle.

After the fire outside the city was extinguished, the enemy troops outside the city who wanted to attack the city found that the city gate had been closed, and the city walls were already full of defending soldiers, and there was no chance to sneak attack.

After the enemy retreated, this side also collected his troops and returned triumphantly. Counting the spoils of war, it was found that a total of 248 Tufan soldiers, 34 Tufan cavalry, and 38 war horses were captured in this battle.

The next day, when Captain Shi, who was still frowning sadly, heard that the enemy army had suddenly attacked the city last night, was completely defeated by our army, won a great victory, and captured hundreds of prisoners, he was immediately overjoyed and overjoyed. I thought to myself, this cavalry battalion is really powerful, and I must ask for credit for them in front of the emperor.
