When Chen Zheng and others arrived, there were already many agents gathering there, and they were stretching their necks to look at the dark hole.

Chen Zheng separated everyone and came to the front. He saw a large hole in the hole wall, revealing a passage extending diagonally downward.

"How did you find it?" Chen Zheng looked at the messy gravel on the ground. No wonder they hadn't discovered this place before... It turned out that the mystery was on the wall of the cave.

"Jerry discovered it, he felt like there was wind here... God knows how he felt it, but I didn't find it anyway." A white man shrugged and patted the black-haired young man next to him on the shoulder.

"..." The black-haired young man stood aside and remained silent.

Chen Zheng did not force him to do this kind of person who was not talking. He nodded to him, took out a strong flashlight and shone it into the depths of the darkness...

...However, nothing was discovered except darkness.

No, I can't say that I didn't find anything. At least Chen Zheng already knew it. There is no doubt that the passage is very long.

Maybe the two infected people are hiding here?

Chen Zheng thought about it, but did not count it rashly, but called the headquarters first: "How about glasses, Cleaner 1, 2 and Explorer 3?"

"The repair has been completed and you can set off at any time."

"Very good, send them to A17."

“…”

A few minutes later, with the rumbling sound of tracks, three newly repaired robots lined up in front of Chen Zheng.

The agents made way for the three robots, and then they drove down below the cave under Chen Zheng's instructions.

“Rumbling…”

"Kazhi..."

Sudden!

The three robots stopped at the same time!

"What's the situation!?" Chen Zheng asked in the channel.

"I don't know... it's a bit like EMP, but it doesn't look like... it's much smaller than EMP's unit power..." The man in glasses was also a little unsure, "Can you give me a visual target?"

"..." Chen Zheng silently raised his personal terminal and sent back the three silent robots not far ahead. After a while... the man with glasses' voice sounded again.

"It should be that there is no damage from the outside...will you pull them out conveniently?"

Chen Zheng looked down at the cables - the three robots still did not have their own power generation devices, so the energy supply and communications were still transmitted by the cables.

It is precisely because of this that the three cables on the ground can be used as ropes to pull back the three robots in front of them.

He did it right away, and Chen Zheng invited several agents to pull the robot in front of him back.

However, when the robots left the cave for a distance, the robots that were originally standing still moved again and began a meticulous self-test work one by one.

However, from the appearance, we can see that the various equipment on the robot showed no sign of damage at all.

"What's going on?" Chen Zheng asked holding the microphone.

"Sir, you can confirm that there is some technological defense method in the cave... Judging from the existing information, any electrical equipment should not work in that channel."

"...A EMP that works continuously and does not burn down electronic components?" Chen Zheng said to himself in confusion.

"Sir, what should we do next?" asked a former agent in a low voice.

"It seems that there is no other way..." Chen Zheng waved his hand and turned around and shouted: "I need three volunteers to accompany me. Except for the volunteers, your work has been completed and you can go back to the tent to rest."

"Apart from those who want to stay, everyone else can go back to the tent and stand by..." Chen Zheng looked at the agents with a large number of people and turned around and left. Only some passionate young men were still standing on the high ground, with a look of unsatisfactory expression on his face.

Wet, furry, sticky... as if I touched the intestinal wall of some kind of animal.
