Guo Baibai's heart fluttered, as if all that was left in the world was the sound of his chest beating inside. She raised her little hand and knocked softly on the door.

"Wu Qi, are you there?" Guo Baibai spoke in a low voice, as if he was expecting something.

There was no response from Wu Qi behind the door, Guo Baibai knocked on the door again, and waited for a long 10 seconds, but still did not hear Wu Qi's voice.

Did Wu Qi sleep? Guo Baibai said in his heart. Her hand slowly reached for the doorknob, and her white and slender five fingers pressed against the cold doorknob. Turn, push the door.

Guo Baibai regretted a little, maybe it would be better to get himself drunk first and then do so. But now, it's too late to think so much, so Guo Baibai closed his eyes and felt into the darkness.

When Guo Baibai opened his eyes again, what caught her eyes was not the scene she expected. Wu Qi's bed was empty, and even the quilt was still folded. On the contrary, the bedroom window is wide open, and the curtains sway from side to side in the cold wind.

Guo Baibai stopped in place in a daze, his hands slid to the sides of his thighs, and he was at a loss.

......

Hundreds of kilometers west of Chang'an District. Wu Qi was wearing a dark gray combat uniform, with a long knife in the scabbard and on his back. His arms and legs swung rapidly, and he kept running at 130 kilometers per hour in a straight line over the silver-moonlit wilderness, swift and silent.

Wu Qi's black eyes were like owls at night to see the dark wilderness, and the perception network was released in all directions, observing the surrounding environment with 100% vigilance at any time.

In the afternoon, Wu Qi was indeed dissuaded by Wang Yan, and he thought a lot about it afterwards, but he couldn't sleep, so he turned out of the room and went straight to the high wall west of Chang'an District.

Wu Qi understands the truth that if you don't enter the tiger's den, you can get the tiger. Now that he and his companions are being hunted by Xinjing's forces, as the leader of the Black Knights, he must do his best to "light up" the unknown shadow areas of the wilderness as much as possible.

It is not dangerous to go into the shadows, but if you get one more piece of information, you will be able to see a way when the pursuers are approaching and fleeing.

The cold wind hunting ground slammed on Wu Qi's body, and there was a sign of winter coming. Wu Qi stepped up his pace, and his figure ran towards the end of the dark abyss-like wilderness.

Wu Qi silently calculated the time, and when the time to leave Chang'an District came to 1 hour and 20 minutes, there was one more thing at the end of the wilderness in Wu Qi's eyes, a tall wall that crossed all areas of the field of vision!

"That's the wall of the border?"

Wu Qi quickly approached the high wall, until he was a kilometer away from the high wall, and he slowly stopped.

It was a 40-meter-high dark gray wall, with a path at the top of the wall for soldiers to walk. As far as the eye can see, a heavy cannon is erected at the top of the high wall every 50 meters, and the black and thick muzzle of the heavy cannon is aimed at the fallen area outside the border pass, like the steel guard of the human frontier.

Wu Qi could see dozens of beams of white light on the high wall, and it was obvious that it was a searchlight set up on the top of the high wall. The end of the searchlight forms a white circle of light on the land of the occupied zone and moves regularly within the set range.

Suddenly, Wu Qi saw a heavy cannon move its muzzle slightly, and immediately fired out a cannon without warning! The earth-shattering sound of cannons clearly reached Wu Qi's ears from a distance of a thousand meters, like a giant roaring.

A tall fountain of dust rose from the land of the Occupied Zone, and a plague species of the Occupied Zone was detected by a searchlight, and was instantly bombarded into a puddle of flesh and mud by heavy artillery.

This is the role of the "guard system" connected to the heavy artillery, which has artificial intelligence to directly detect whether the approaching target is a plague species, and then automatically gives the heavy artillery an attack order.

After the cannon kills a plague seed near a high wall with a single hit, the mechanical structure inside automatically reloads a new shell, making a rumbling sound of heavy objects rubbing and rolling.

Wu Qi witnessed the unguarded system of the high walls of the border gates, and had a new estimate of the military strength of the border army. He looked all the way from the left side of the wall to the right, and as far as the eye could see, he didn't see anything that looked like a town base.

"It seems like not." Wu Qi wrote it down. Chang'an District all the way to the west, there is no Zhenjiang base near the high wall of the border pass. That is to say, there is no army at the border here, but it cannot be said that there is no one, after all, he is not sure what the structure of the thick high wall is, and it is possible to live inside, and there are some maintenance personnel.

Wu Qi confirmed one guess and was ready to confirm the next one. He took a step forward, and several searchlights on the high walls suddenly swept 180 degrees. The white circle of searchlight streaked across the wilderness in front of Wu Qi, skimming the ground in front of his feet, and then continued to turn the remaining 180 degrees, redeploying the searchlight range to the occupied area.

Wu Qi's right foot froze in place, and the cells all over his body faintly emitted a faint sense of electricity. A cold sweat broke out on his back, and he hesitated before deciding to take another step forward.

The scene just now was exactly what Wu Qi guessed. Since the high wall is so good at guarding, it will not only probe the outside of the wall, but completely abandon the inside of the wall.

The muzzles of the heavy artillery were all aimed outside the wall, and in the worst case, at night, the guards of the high wall would fire on any target they could detect. But it takes time for the heavy artillery to move from outside the wall to inside the wall, and Wu Qi thought of the worst outcome and decided to try it further.

Wu Qi waited for 20 seconds, the searchlight of the high wall turned into the wall again, and he stepped on the area where the original searchlight had been searched, and this time the white light of the searchlight hit him head-on.

The dazzling white light blocked most of Wu Qi's vision, and it was difficult for Wu Qi to open his eyes, let alone see the movement of the heavy artillery on the high wall.

A faint sense of electricity instantly filled his body, Wu Qi immediately retreated, and the strength accumulated in the muscles of his legs helped him move away from the range of the searchlight in an instant, and then the searchlight turned away as before.

As a result, the heavy artillery did not fire.

Wu Qi breathed a sigh of relief, it seems that the guard system of the high wall is quite high, and it is found that ordinary people will not shoot cannons, so they must be able to screen the plague species.

After probing the information at the border pass, Wu Qi thought he could return. This trip was very rewarding. He determined that if the pursuers were killed, he could take his companions to run in the direction of the border pass, and as a last resort, crossing the high wall of the border pass and escaping to the occupied area was also a way to die and survive.

There are only three ways to escape, to the south, to the occupied area, and to the north, Wu Qi subconsciously doesn't want to go south, because he walked all the way here from the southwest corner of the mainland. Wu Qi couldn't tell if this was a kind of heart-to-heart with Sister Ruoying, he felt that Sister Ruoying couldn't still stay in the southwest corner of the mainland, the vast land, she could go anywhere.

Going south is the least likely option to find Sister Ruoying.

Wu Qi turned around and took a step to return to Chang'an District. At this moment, he felt a strong seismic wave from the ground under his feet out of thin air, and the sense of electricity that foresaw danger went from the soles of his feet to the top of his head like a thunderbolt of lightning!
