There is no signal on the mobile phone, and Si Chen cannot report the situation even if he wants to.

Looking at the bright and sunny world outside the back door, which could not be seen to the side at a glance, Si Chen wanted to go in for detection, but he didn't dare.

He still hasn't figured out the ruins he discovered during the drone inspection.

Drone inspection is always not as real as what you see in person.

Moreover, Si Chen had never seen the texture of the material captured back before.

Of course, it may be that he is ignorant!

He didn't feel anything bad at the back door for the time being, but the air smelled a little hot, and there was a smell of roasted earth in the air.

What is this description? What does roasted earth smell like???

Chen Qiqi is very interested in ancient times and the world of backdoors, but unfortunately she doesn’t have the courage to step outside at the moment.

She was afraid that if she stepped out of the door, she would not be able to come back.

Then she will cry to death like Meng Jiangnu crying at the Great Wall!!!

So she should wait for Si Chen and the others to check the safety situation before taking a look.

Without detection tools, it was pointless for Chen Qiqi and Si Chen to just sit at the back door, so they closed the door and went back.

Unfortunately, if they had waited a little longer, they would have seen that the back door had changed.

At this time, the bright sunshine in the world at the back door has disappeared and has turned into a dark world, where you can't see your fingers.

Outside, the material Si Chen asked his subordinates to send to the Imperial Capital has been detected and is a very high-grade synthetic metal material.

It is much better than aviation materials. Many people in the institute are asking where this stuff comes from?

If we have this material, our motherland's aviation industry will definitely be able to make further progress.

Not only aviation, but also military weapons can use this material.

Because this material is hard enough, highly compatible, resistant to high temperatures and extreme cold.

Everyone thought this material was a new type of material obtained from some foreign research institutes in China, so they called Si Chen’s immediate superior.

How did Si Chen's immediate boss Yu Yongqing know this? He only knew that Si Chen and the others pulled this thing back from a time-traveling point.

He didn't know anything else, and that brat Si Chen didn't report it to him. He only knew some clues from the members of his team.

After finally getting rid of the scientific research geeks, Yu Yongqing quickly called Ma Jinghua to ask about the situation.

Ma Jinghua felt that it was not convenient to talk about some things on the phone, so he bought the latest flight from G Province to the Imperial Capital.

After he returned to the imperial capital to report the situation to Yu Yongqing, he rushed back overnight.

After Yu Yongqing learned about Si Chen and Chen Qiqi's situation, instead of feeling happy or delighted, he felt more worried and sad.

I'm worried about something happening to them. What's worrying is that there are two crossing points in one place at the same time, which is wrong.

He asked Ma Jinghua to bring a message to Si Chen, asking Si Chen to take Chen Qiqi to withdraw when he saw something was wrong.

Nothing matters.

But at this moment, Chen Qiqi and Si Chen were sitting in the living room, staring at each other.

After returning from the back door, Chen Qiqi asked Si Chen: "Is the drone unusable? I don't think they took the drone away."

Si Chen: "It's not that I don't have to use it, but I can't operate such a large drone by myself since Ma Jinghua and the others are not here."

Their drone is a professional detection drone. Although it can be operated by one person, it will take some time.

In addition, their two drones are new products from a certain research institute, and their endurance is not very sufficient, so they cannot detect farther.

Si Chen had a premonition that the world of backdoors seemed very big!
