At this moment, Ye Lei had no idea that Chen Xueer and Sarah in the shelter had been kidnapped, even though the satellite phone was not placed in the space.

Unfortunately, when they entered the underground city, the satellite phone lost all signal, as if they had entered a completely isolated place.

This place was originally a secret underground military factory. In that turbulent era, in order to evade enemy satellite reconnaissance, a lot of manpower and resources were spent to hollow out the entire mountain and manufacture a large number of weapons to deal with the war.

Later, with the arrival of peacetime, there was no longer any need to produce large quantities of weapons, and the place gradually fell into disuse, becoming the forgotten 863 underground base.

However, things are unpredictable. The sudden outbreak of a heatwave brought the survivors back to this place. Perhaps only here could they escape the increasingly severe heat and find their last refuge.

Entering the underground city, there is a main road as wide as the entrance, with rooms of various sizes on both sides, some of which are production workshops, some of which are offices, etc.

Most of these rooms appear dilapidated, but many slogans remain on the walls. These slogans once inspired countless people, and although the writing is now blurred, one can still feel the enthusiasm and passion of that time.

The living and working areas were strictly separated, a division that reflected the people's pursuit of order at the time. Although a long time has passed, the slogans on the rock walls are still clearly visible, as if they bear witness to the glorious years that once existed here.

To accommodate the needs of more survivors, many brick walls were demolished, leaving only some load-bearing walls supporting the caves.

As a result, the underground city's space was greatly expanded, making the entire area look exceptionally spacious. The survivors who entered the underground city began to look for suitable places to live.

Under the guidance of military personnel, they carried out the resettlement work in an orderly manner, each with expectant eyes, hoping to find a safe and comfortable place to live.

When Ye Lei looked around, all he saw was chaos. There were crowds of people everywhere, and the noise was deafening. He couldn't tell which way was which.

Finding someone here is harder than climbing to heaven, like searching for a needle in a vast sea of ​​people. Even Ye Lei felt at a loss, not knowing how to find the person he was looking for.

However, since entering the underground city, Ma Jing has been busy. She went around asking people and identifying them, but all she saw were unfamiliar faces, and there was no substantial progress.

Ye Lei frowned slightly. At this rate, when would they ever find the person they were looking for? He was still waiting to complete the tasks assigned by the system!

Just as he was frowning in distress, a familiar face came into view. It was Deputy Captain Liu, who was busy directing the resettlement work.

"Hello, Deputy Captain Liu!"

Ye Lei walked over to greet him and said.

"Ye Lei, when did you arrive? Haha...long time no see!"

Deputy Captain Liu, abandoning his usual serious expression, said with a smile.

"Deputy Captain Liu seems to be very busy. I just arrived too."

Ye Lei needed something from him, so naturally, he had to be polite.

"You're new here? You must not be familiar with the dungeon. Let me show you around!"

Deputy Captain Liu probably also thought that he might need Ye Lei's help in the future, so he was very polite.

"Is this a good idea? You seem very busy!"

"Well, it's alright. Anyway, the resettlement work won't be finished anytime soon, so let's take it slow!"

Deputy Captain Liu understood that he would likely be living here until the end of the apocalypse, and there was plenty of time ahead.

"Then we've got Deputy Captain Liu."

Ye Lei also wanted to understand the structure of the underground city as soon as possible.

"Actually, this underground city has two levels. The lower level is where the government agencies and our military are stationed, and the upper level is where ordinary survivors live!"

"So, have the government departments moved here yet?"

"Of course, the relocation of ordinary survivors only began after the lower level was properly settled!"

Deputy Captain Liu said with a smile, "So the relocation was planned after all."

"How can we get to the basement?"

"You can go down to the area guarded by soldiers over there. This is to ensure a quiet working environment downstairs!"

Deputy Captain Liu pointed to a corner in the distance, where soldiers were standing guard.

"Oh, I see. Anna, did you hear that? Go down and find your father!"

Ye Lei turned around and said to Beanna behind him.

"Okay, thanks, Brother Lei."

When Beanna heard that she could go see her father, she ran off excitedly.

"So, if we want to find someone here, is there any way?"

This is what Ye Lei really wants to know.

"Yes, there is an information desk at the entrance of the cave. You can go there to find out."

"We asked around, and they said it's here, but they don't have a specific location. Even with so many people, we can't find it!"

"Oh, I see. Now that the person is here, things are easier. What's the name of the person you're looking for? I'll help you."

Deputy Captain Liu was also happy to cultivate a good relationship with Ye Lei.

"That would be very kind of you. His name is Ma Mingzhe."

"No problem, watch me!"

Deputy Captain Liu took a megaphone from the waist of a soldier not far away and shouted into it, "Ma Mingzhe, please come to me immediately after hearing this announcement, please..."

After the recording was finished, it was played on a loop. Although the sound was not loud, it could be heard in every corner of this almost enclosed underground city.

"That's a great idea, why didn't I think of that?"

Watching Deputy Captain Liu's actions, Ye Lei finally understood that this was the best way to find the person.

"Even if you've thought of it, we won't allow you to shout it out randomly. Otherwise, what kind of place would this place be, right?"

Deputy Captain Liu said with a smile that even loud noises here are stopped by soldiers.

"You're right, you guys do have a way."

Ye Lei now realized that he was really no longer suited to living in a group.

"We were forced into it, there was no other way!"

"So how do you solve the electricity problem while living here?"

The two moved forward slowly following the sound of the horn. Ye Lei saw the hanging incandescent light bulb and asked curiously.

"Oh, back when it was a military factory, there was a generator room outside the cave. Now it's solar-powered, but as the population grows, solar power isn't enough. We're preparing to develop geothermal energy underground."

"Geothermal energy? Is it right down here? Is that energy generated by magma?"

Ye Lei suddenly wondered, if there really is lava here, could there really be lava zombies?

"Yes, you're right, we should make the most of everything!"

Deputy Captain Liu replied with a smile, but he was unaware of Ye Lei's concerns.
