The four of them rushed into the bomb shelter, closed the iron door, and did not rush to leave, but quietly squatted by the door and listened to the movement outside.

After a while, Cheng Ming clearly heard the sound of sharp footsteps outside the cave, thinking that it must be an alien creature wandering outside, looking for something, just when the sound was about to approach the entrance of the cave, its footsteps stopped abruptly, and Cheng Ming's heart had already jumped to his throat at this time, and he couldn't even move nervously.

And Yuanyang Lao Dao glanced at Lin Fan thoughtfully, because at the moment when the footsteps stopped, he clearly saw that Lin Fan's eyes lit up, it was a bright light of no color, and it was only for a moment, it was gone, and after that flash of light, the footsteps outside the door stopped, and after about 1 minute, the footsteps outside the door sounded again, only this time it was the footsteps of leaving.

Cheng Ming breathed a sigh of relief, wiped the cold sweat on his forehead, rested for a while, and then led everyone to the depths of the air-raid shelter.

Back at the research institute, Cheng Ming asked Lin Fan to take Ke'er to cook, while he beckoned Yuanyang Daoren to sit next to the platform in the hall, poured a glass of water for Daoren and asked.

"Yuanyang Zhenren, what the hell is going on?"

Lao Dao looked at Cheng Ming with interest, did not answer his question, but asked to himself.

"Why aren't you nervous now, aren't you afraid that I'm lying to you and harming you?"

Cheng Ming smiled helplessly, and slandered in his heart, you are so familiar with this place, I want to guard against it, can I prevent it? Although I thought so in my heart, of course I couldn't say it on my lips.

"The real person laughed, the kid was really scared by your sudden arrival, but they are all humans, you will not harm me."

The Taoist seemed to see that Cheng Mingyan was insincere, and he didn't ridicule Cheng Ming anymore, and said seriously.

"Cheng Jushi should know who I am."

"I probably know something, I've read the notes left by the staff here, this should be what you designated to set up, but I don't know who you are."

Lao Dao nodded slightly after hearing this, and did not say anything, but asked again.

"Cheng Jushi, have you seen that gem?" Seeing Cheng Ming nodding, Lao Dao then asked, "Then what do you think is the use of that gem?" ”

Cheng Ming didn't know how to answer, the span of the question was a bit large, not to mention, except for the fact that after taking a look at the gem when he first came in, Cheng Ming didn't pay attention to the gem anymore, not that Cheng Ming was not curious, but that the fainting made Cheng Ming feel palpitations, fortunately it was safe here, but who said that it was really safe here? If he touches the crystal cabinet again, will he fall unconscious again, and will there be no accidents during the coma, he still has to take care of the two little ones, and he can't afford to miss a little.

So from the perspective of safety, Cheng Ming suppressed the curiosity in his heart, and only occasionally studied the information left here, but those materials were too professional and he couldn't understand it, so in fact, he really didn't know anything about that gem.

When Lao Dao saw Cheng Ming's appearance, he also guessed seven, seven, eight, eight, and said.

"Actually, we still don't know what the use of that gem is, but two years ago, the headquarters suddenly detected that the gem here was activated, so I rushed here to take a look, who knew that it took 2 years to get here."

We? Headquarters? Activation? Cheng Ming was shocked when he suddenly heard these words, and hurriedly interrupted the old Tao who was about to continue, and hurriedly asked.

"Real person, what do you mean by us, headquarters, does the government still exist?"

Seeing Cheng Ming asking, Lao Dao nodded with a smile and said.

"Yes, the government has always existed, just because the alien creatures are too powerful, and our weapons can't do any harm to them, so we have moved the base to a more secluded place, and stepped up research on weapons that can fight against alien creatures, hoping that we can one day regain what we lost."

Cheng Ming's eyes were already red when he heard this, tears flowed down the corners of his eyes, the fugitive life in the past few years made him physically and mentally exhausted, along the way, watching the city was destroyed, compatriots were killed, the desolation and helplessness in his heart could not be described in words, and at this time, when he heard that the government still existed, and he was still working hard to fight back, Cheng Ming's heart suddenly settled down a lot, just like a child who had been wandering for a long time, suddenly seeing his parents, that sense of security, made his silent heart begin to recover.

"I knew that the country would not abandon us, I knew it, I knew it~~~"

Cheng Ming cried with joy, kept chattering, and after a long time, he regained his composure and said.

"Zhenren, there must be something wrong with you coming here this time, you tell me what you need me to do, and I will do my best to assist you."

Lao Dao smiled with relief, and was about to speak, but saw Lin Fan walking out with a pot, and Ke'er walking out with dishes and chopsticks.

"Yo, the meal is ready, Cheng Jushi, don't you mind if we finish eating first and then talk, I haven't eaten for a few days, and I'm really hungry at this time."

Cheng Ming touched the tears that fell from the corners of his eyes and said with a smile.

"Okay, eat first, Xiaofan, Ke'er, this one you should be called... It should be called..."

"Call grandpa, these two little guys are really spirited, and they will definitely do something in the future."

"Hello grandpa." The two little ones screamed very well-behaved.

Lao Dao touched Ke'er's head with a smile, said yes vigorously, and wanted to touch Lin Fan's head again, but after hesitating for a long time, he still put down his hand and didn't touch it.

Cheng Ming looked at a few people like that, and suddenly felt very warm and safe, with one more elder, more like a home.

"Come on, eat first." Cheng Ming greeted a few people, and then gave Lao Dao a bowl first, and then served a good meal to the two little guys, and finally served a bowl to himself, and ate it, this meal was very warm, Lao Dao asked some questions to the two little guys from time to time in the interval between meals, such as simple math problems, text problems, etc., just like a primary school teacher is testing his own students, and the two little guys are also fluent in answers, leading Lao Dao to a happy smile.

After eating, the two little ones went to clean up the dishes and chopsticks, while Cheng Ming entered the laboratory with Lao Dao and came to the place where the gem was stored.

At this time, the gem seems to be a little dimmer than the last time Cheng Ming saw it, after all, it has been another 2 years, and the uninterrupted use of the energy on it, no matter how huge it is, there is a moment of exhaustion.

"Looks like I'm not too late." Lao Dao looked at the gem and muttered to himself.

"Real person, what do you say this gem is for?"

Lao Dao looked back at Cheng Ming carefully, and thought for a long time before saying.

"Cheng Jushi, what I want to say next, you have to listen carefully, maybe this is a big turnaround, or maybe it is the beginning of a catastrophe."
