"Black box...what does this mean."

This is obviously a special term in the prehistoric era and has long been lost in Tonghui City.

Musashino manipulated Bai Xiaoyao and explained:

"In the prehistoric era, a 'black box' that records real-time status will be installed on it. Even if the plane crashes, just find the black box...

"It can also restore the truth about the accident."

Spear asked quickly:

"Your black box recording room is likely to have the cause of the base accident?"

"That's right."

Before we knew it, this team had already centered on Bai Xiaoyao.

To be more precise, Musashino is the center.

Bang!

The city lord directly used energy to blow the door lock.

Squeak-

The door opens and the automatic lighting lights are on.

Surprisingly, the interior space of this black box recording room is very small.

It's similar to a normal lift.

On the small desk in front is a telegraph machine with a special shape, and a pile of document paper is scattered around it.

The city lord walked forward and picked up one of the pages casually:

"Tinder base construction map."

Sure enough, this is a maze-shaped structure.

A small black dot sandwiched in it is Tonghui City. Roughly estimated, the scale of this base is very likely... equivalent to a super-large city.

“What a horrible scale.”

He sighed sincerely.

It is really unimaginable that humans have reached their peak technology in the prehistoric era.

Musashino also took a look.

He saw directly outside the base, there were a bunch of turbine-shaped devices.

"Curveability...motorized vortex prop?"

This is the name of these machines.

The notes on the drawings are:

Curvature maneuverable vortex propeller, the most powerful weapon of mankind today, prevents external invasion and interference by agitation of curvature and creating phenomena such as space disorder.

It can fight against 10th-order mutants at a minimum.

The city lord slowly widened his eyes:

Could it be...

This is the truth about the turbulence of time and space?!

"wrong.
