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

Chen Zheng separated the crowd and came to the front, where he saw that a large hole had been carved into the cave wall, revealing a passage that extended diagonally downward.

"How did you find out?" Chen Zheng looked at the mess of rubble on the ground, no wonder they hadn't noticed it before...... It turns out that the mystery is on the cave wall.

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

"......" The black-haired youth stood aside and was silent.

For this kind of person who doesn't like to talk, Chen Zheng didn't force him, nodded at him, took out a strong flashlight and shone it into the depths of darkness......

…… Yet nothing was found but darkness.

No, it can't be said that he didn't find it, at least Chen Zheng already knew it, and there was no doubt that this passage was very long.

Maybe those two infected are hiding here?

Chen Zheng thought about it, and instead of rushing into it, he called the headquarters first: "Glasses, what is the situation of Cleaner No. 1, No. 2 and Explorer No. 3?" ”

"It's been repaired, and it's ready to go."

"Very well, send them to A17."

“……”

A few minutes later, with the rumbling sound of crawlers, three newly repaired robots appeared in front of Chen Zheng in a line.

The agents made way for the three robots, and they drove down the cave at Chen's instructions.

"Rumble ......"

"Squeak......!"

Suddenly!

Three robots stopped at the same time!

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

"I don't know...... It's kind of like EMP, but not quite like ...... It's much less than the unit power of the EMP......" 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 appearance of the three silent robots not far in front of him, and after a while...... The glasses man's voice rang out again.

"From the outside, it shouldn't have been damaged...... Is it convenient for you to pull them out? ”

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

Because of this, the three cables on the ground can be used as ropes to pull back the three robots in front of them.

As soon as he said it, Chen Zheng beckoned a few agents to pull the robot in front of him back.

However, when the robots left the cave for a certain distance, the robots that had been standing still moved again and began to carry out detailed self-inspection work one by one.

However, it can be seen from the appearance that the various equipment on the robot shows no signs of damage.

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

"My lord, it's already certain. There's some sort of technological defense in that cavern...... Based on the available information, any equipment that uses electricity should not work in that channel. ”

“…… An EMP that acts continuously and does not burn out the electronic components? Chen Zheng muttered to himself in confusion.

"My lord, what are we going to do next?" A former agent asked in a low voice.

"It seems that there is no other way...... Chen Zheng waved his hand, turned around and shouted: "I need 3 volunteers to accompany me, except for the volunteers, your work is done, you can go back to the tent to rest." ”

"Except for those who want to stay, the others can go back to the tent and stand by......" Chen Zheng looked at the large number of agents who turned around and left, only three or two agents who didn't know what to do.

"Thank you for your support, can you get to know us?" Chen Zheng stretched out his hand and shook hands with several people.

"George."

"Zhang Chao."

"Chen Minghui."

Chen Zheng chatted with them casually while pulling up the information of several people from the database.

George, British, served in 20.

Zhang Chao, a native of the country, is one of Lao Wang's subordinates.

Tan Ming Fai, Singaporean, other unknown.

After getting to know a few people at a cursory, Chen Zheng waved his hand and motioned for Scar to go back - he was still wearing power armor, and in this case, it was obvious that he could not venture into the cave with Chen Zheng.

"Let's go."

Chen Zheng put on a filter mask and walked down first.

The other people looked at each other, put on their filter masks, and followed Chen Zheng into the darkness.

"Click."

When Chen Zheng walked into the darkness, he gently pushed the switch, and the miner's lamp hanging on his forehead lit up, dispelling the darkness in front of him.

As Chen Zheng took the lead in turning on the lights, the others naturally turned on their own miner's lights.

Four pillars of light followed the gaze of the four men as they moved through the cavern, checking for any possible danger...... However, more than ten minutes have passed, and the hole behind him has become a small dot, but the calm in this downward passage is still calm.

"Look, my lord!"

With the pointing of a pillar of light, Chen Zheng finally saw the end of this passage.

"We ......"

"Click!"

Before Chen Zheng finished speaking, the accident suddenly came!

A few people had just come in through the passage, and before they could look around, the lights went out - all the miner's lights were out!
