Anti-gravity technology

Pa, pa, pa ...

A few mutated monkeys quickly pressed on the steel door, making a banging sound.

Crack! Crack!

This process took less than five seconds.

A crisp cracking sound was heard ...

Hu hu hu!

Then, the steel door slowly opened, and a huge gust of wind blew out from the inside. The surrounding fine sand was all blown away ... If the door was opened from the inside, the sand piled on top would also be blown away, and no one would be able to enter.

&Quot; what an incredible principle. It's built in such a place, and not a single grain of sand can enter. &Quot;

A mutated monkey was watching excitedly at the side.

He muttered to himself.

When he said that, the monkey changed into white clothes. He was definitely more reliable than any so-called expert.

"It is indeed incredible! Monkeys, and everyone else, from now on, don't just stand here and watch. Remember the distance from here ..."

Chi Chi!
