super unscrupulous student

Zhuo Yifan hurriedly looked over for the sound, and found that one of the soldiers had already cleaned out about five or six square meters of steel plate, and a crack was found on the edge of the steel plate.It seems to be a crack in splicing, or a passage in and out!

"What is this? A door? Continue cleaning, centering on this crack!" Zhuo Yifan squinted his eyes and observed for a while, then ordered decisively!

So with that crack as the center, a large area of ​​steel plates was quickly cleared.Now Zhuo Yifan can verify his previous guess!This crack should be an entrance and exit.Therefore, the soil layer buried here, because of the frequent entry and exit, only made some simple camouflage, and it was very easy to be identified and discovered.But the more you dig around, the thicker the soil layer becomes, so thick that even someone standing on it can't find it.What does this represent?

This shows that the steel plate has grown to a certain extent, or in other words, the area of ​​the metal plate on the top floor of the underground fortification has grown to an incredible extent.How did those people do it?It is possible to build such a huge underground fortification without destroying the original landform and vegetation.If only placing such a large iron plate in the middle of the mountain, it can be said to be an impossible task.Not to mention building a secret base under this steel plate!

But all this happened in front of his eyes, he couldn't help but believe it.

At this moment, the communications soldier handed over the phone again.Said it was Xie Dongting's phone call again!

"Brother-in-law, how are you doing?" Zhuo Yifan answered the phone and asked bluntly.

"We found a large piece of steel plate, the size of which is beyond estimation! I wonder if they have hollowed out the bottom of the mountain?" Xie Dongting said aloud.

"Well! It's the same on my side. Now it seems that the steel plate on my side is probably integrated with the steel plate on your side. How did they get such a huge steel plate in the middle of the mountain? Is there such a technical means to do this?" Zhuo Yifan was also surprised.In his opinion, the underground base he encountered in France has already opened his eyes.And dig out a basement in the middle of the city, although the area is relatively large, it can still be done!But this is a mountain!How to solve it by technical means?How did the large machinery get in?With this series of questions, is the other party a god?

"I found a circular entrance here. But I can't open it! What about your side?" Xie Dongting asked quickly.

"It's the same on my side. No wonder the traces I found before, but I can't find half a person. I guess they should all be transferred to the mountainside!" Zhuo Yifan said with a cold snort.

"Wait... Even if they all went in, who did the camouflage on the surface of the entrance?" Xie Dongting suddenly thought of something at this time, and raised his own doubts.

Zhuo Yifan couldn't help being taken aback when he heard the words: "That's right! This must require a certain number of people to do cover work on it. And one or two people can't complete it in a short period of time!"

"That's right! It is estimated that they are on the mountain, and there are still some people wandering around! Let everyone be careful, and don't let down your vigilance if there is any trouble!" Xie Dongting said in a deep voice.

"Then what should we do now? Shall we find a way to open this entrance and go in?" Zhuo Yifan asked.
