In the midnight Fangcheng, under the cover of night, it was extremely silent, and in the garrison camp outside the city, there was a snoring sound in the tent, and only the guards on the city gate and the patrols in the city patrolled back and forth from time to time.

The guards on the city gate, always pay attention to every move outside the city gate, once there is any wind and grass, they will quickly sound the alarm, there are 500 defenders on duty at night under the city gate, the patrol team receives the alarm, and will also go to the garrison camp as soon as possible, gather a large army, within a quarter of an hour, the city gate will gather a large number of defenders, which is also to prevent the enemy from attacking the city.

At night, in the dark expanse outside the city gate, there were several strange grasses, moving slowly. I don't know if the speed of those black shadows was too slow, or the sky was too dark, those few moving grass piles, under the eyes of the guards, slowly moved to the blind spot under the city gate.

A slight cricket cry came from under the city gate, and then, one after another, several batches of grass slowly moved towards the city gate from different directions.

Tonight was not around fifteen, only a few dim stars hung in the dark night sky, and the thin crescent moon was often hidden behind the dark clouds, and the city gate guards were in darkness as far as they could see, so they had to listen carefully to all kinds of strange noises to judge whether there was an enemy situation.

Unloading the grass, Yang Lei and the others showed their figures, they silently gestured to each other, each took out a finger-thick bamboo tube in their arms, looked at each other, and scattered around.

Taking advantage of the night, ten black shadows clinged to the wall more than ten meters high, slowly climbing upward.

After a long time, when they were about to reach the top, the black shadows took out a flying claw from their arms, gently buckled it to the top of the wall, grabbed the rope with one hand to support their bodies, and took out a palm-sized, "Z"-shaped corner mirror from their arms with the other hand, and quietly probed the camera to the city wall, turning around, through the faint light of the torches on the city wall, the black shadows saw the position of the guards from the corner mirror, and then quickly estimated the best way to sneak attack.

The first cricket sounded, followed by the second and third...... It wasn't until the tenth sound fell, and ten seconds later, ten black shadows jumped up the city wall in unison, blowing the bamboo tube in their hands at the stunned guards.

The attack was only for a moment, and before the defenders on the city wall could react, it was dark in front of their eyes and they fainted.

The eyes of the ten people were bright, and while quickly blowing out the anesthetic needle from the bamboo tube, they carefully supported the fallen guard, trying not to make too much noise.

After the defenders on the city wall were settled, the ten people re-fixed the flying claws again, threw down the rope, and made three bird calls in succession, not long after the bird calls fell, more black shadows came one after another outside the city gate, grabbed the rope and began to climb up.

Dealing with the defenders on the city wall is just breaking through the first line of defense, and the next step is to solve the other group of guards who are sleepy and ready to change shifts at the entrance of the city wall.

The first ten people had few anesthetic needles left, and they waited patiently for the people behind them to catch up, and after a faint sound of breaking through the air, the second line of defense was breached.

Yang Lei made a gesture, and then the soldiers were divided into four ways. Staying on the city wall all the way, he quickly changed into the clothes of a fainted soldier, and patrolled the city, and from a distance, there was nothing abnormal at the city gate; all the way outside the ear rooms on both sides of the city wall, guarding the reserve defenders who were sleeping soundly inside; The third road went to the garrison camp, and the fourth road led by Zhao Ziyang to the general's mansion.

No one knew that the gate of Fangcheng was taken by a team of 100 people silently.

In the General's Mansion, Zhao Ziyi, who seemed to be sleeping soundly, had already jumped up quickly when he noticed that someone was invading: "Who! ”
