"Entering through the city wall will inevitably be discovered, and it is also risky for a black-robed person to enter through the city gate, and I think the only way to climb the city wall is the most reliable. Yang Shi proposed.

"I've seen it, the black-robed people they patrol are all in teams of three, as long as I can kill them in an instant without alerting the others, I will have a chance. ”

Qingchen nodded and said, "What you need to pay attention to is not to make a move when the two teams of black-robed people patrolling are staggered, otherwise you will have to face six black-robed people." ”

The three of them made a decision, and without delay, they climbed up against the city wall.

Fortunately, the wall was made of stone bricks, and there were some gaps between the stone bricks, which allowed them to crawl without using their aura.

As for the ability to fly, it is naturally impossible to use, which requires a lot of aura output, and it is easy to be detected.

Just in case other black-robed people happened to come back in their direction, the three of them quickly climbed to the edge of the city wall and were unnoticed.

Qingchen released a sense of non-existence, and only his perception was highly concealed, and if Yang Shi released his perception, it was possible to be detected.

After confirming that there were only three black-robed people above at this time, Yang Shi and the others were ready to make a move.

The moment they made eye contact, the three of them jumped up suddenly.

Yang Shi's gaze immediately locked on the black-robed man who was facing away from him in front of him, and his probe grabbed the black-robed man's head like thunder.

The cold qi was released, and it instantly froze the black-robed man's face, making him unable to make a sound at the first time, and then the ice spread from the top of the black-robed man's head and directly froze his whole body.

Everything happens in the blink of an eye.

Sensing that the black-robed man who had turned into an ice sculpture was not dead, he immediately reached out and pressed it to his heart, and his strength penetrated into the ice, entering the body of the black-robed man and directly shattering his heart, and he couldn't die anymore.

At the same time, Qingchen and Qingxin had already unknowingly killed the other two black-robed people.

The black-robed men of the other teams were still some distance away from here, and they were glad that there were small turrets built on the city wall, one every few hundred meters, which was used to store energy cannons before it was occupied by the Black Groups, and it was also a place for soldiers to rest and play cards.

Thanks to the existence of the small turrets of these turrets, the sight of the other black-robed people on the city wall was blocked, otherwise they would have to think of other ways.

Put the corpse of the dead black-robed man directly into the Qiankun bag, and at the same time put themselves on the same black robe as them, although I don't know if this camouflage has any effect, but it's always okay to give it a try.

In about a minute, the other patrolling teams would come here, and Yang Shi and the three of them had to leave before they arrived.

When his eyes fell on the city, there were no black-robed people lingering on the edge of the city wall, only a few trees that had been broken in two were planted aside.

Seeing this, the three of them immediately jumped down and left quickly.

After a minute, the alarm was not raised in the city, apparently not aware of the missing three black-robed men on the city wall.

"It seems that those black-robed people on patrol are all reformers who are only responsible for fighting, right. Yang Shi said.

For these transformed, having one more or less companion has no effect at all, and they don't have the ability to think about why the three people are missing.

This also gave Yang Shi and the three of them more time to explore this gathering place, without worrying about revealing their whereabouts immediately.

Walk through the darkness and avoid the black-robed people who rush through the streets.

"Where are we going to find the real person next?" Chyoshin asked.

Yang Shi thought for a while and said: "It doesn't have to be a black soul servant, after all, the risk of challenging them is a bit big, and they may not be able to catch them, since there are reformed people, then there must be experimenters who specialize in research, they can't be transformed people, you can try to catch a few experimenters first." ”

Qingchen nodded and said, "Yes." ”

"But we're not sure if there are any experimenters here. Qingxin asked.

"I've seen a lot of reformers with missing arms and legs entering this city, obviously to receive repair treatment, and it's very likely that there is an experimental base here, so you can look for it first. "Yang Shi had noticed it before, and now he mentioned it.

In order to improve the efficiency of the search, the three decided to split up.

Yang Shi looked around, trying his best to find some places that looked like experimental bases, but fortunately, this city was not small, although there were thousands of black-robed people, they were relatively scattered in the entire city.

The three of Yang Shi hid their bodies as much as possible so as not to be discovered.

In this way, more than half an hour passed, and Yang Shi separately checked seven or eight buildings suspected of being experimental bases, but none of them matched.

"The experimental base should be regarded as a relatively important place for the black base organization, and it is unlikely that it will be arranged to be built on the edge of the city, and secondly, there should be a large number of black-robed people guarding it. Yang Shi kept thinking in his heart, turned around and walked towards the center of the city.

In the center of the city is a large square, which should have been the most prosperous area for people, but now this square is full of ruins and ruins, and the stone brick floor is also potholed and badly damaged.

After being overrun by the Black Guys, it is clear that they have no intention of building this place.

"There's no ...... here either" Yang Shi hid under a piece of ruins outside the square, and after scanning around, he found no more.

At this time, the last few black-robed people walked past the square, and Yang Shi seized the time to burst out from under the ruins, turning into a breeze across the entire square and coming to the opposite street.

Continuing his search, he finally made a discovery, after rounding a few streets.

Halfway down the street, it was suddenly blocked by the ruins piled up high.

The ruins were as tall as a three-story building, not only on his street, but also on several adjacent streets.

This situation made him know that there must be something on the other side of the ruins, maybe the experimental base he was looking for.

At this moment, several black-robed people who looked like they had not been slightly injured walked towards here, stepped on the pile of ruins blocking the road, and jumped down.

Yang Shi saw it in his eyes, thought about it and decided to go up and investigate.

Quietly climbed up, looking through the top gap to the other side of the ruins.

Only then did he find that the pile of ruins not only blocked the road on his side, but directly surrounded a huge ring, wrapping a black metal complex inside.

Hundreds of black-robed people walked through the complex, and the injured black-robed people before the wrap were also quickly entered, and found one of the low square buildings to enter.

From the outside, this square building does not look like an experimental base, but Yang Shi felt the need to go over and have a look.
