The End Of The World Is Coming: I Am Bound To The Red Police, And There Are Millions Of Violent Sold

He can't build a third-tier Kirov airship?

Satisfy your curiosity?

"System, upgrade those three Kirov empty courts to level three!"

Su Yan pointed out two Kirov ships that looked more pleasing to the eye, and directly let the system upgrade them to level three.

"Drip! The commander spent a lot of resources and upgraded the Kirov airship to the third level! It's under construction..."

"Drip! It is detected that the commander's current tank factory level is too low to upgrade Kirov, and now the system will automatically upgrade it..."

"The system adopts the method of integrating and upgrading buildings, automatically upgrading ten low-level tank factories to second-level tank factories, and expanding the size on a large scale. It also uses underground voids to compress the building area."

"Drip! The chariot factory has been successfully upgraded!"

Accompanied by the sound of the system, Su Yan heard a violent sound.

"boom!!!!"

The entire ground trembled, and strong fluctuations occurred on the ground.

Originally Su Yan built close to twenty-ten tank factories around the base.

But at this time...these tank factories have all disappeared without a trace!

It's like drilling into the ground.

And it was also at this time that the ground began to undergo tremendous changes, and it could be clearly seen that some drastic changes had definitely taken place beneath the ground.

Su Yan floated down from the sky.

into the ground.

The entrance is a light door that looks very sci-fi, which feels like a portal.

Connected to the ends of the world.

The moment Su Yan entered.

"Drip! Authentication is successful! Welcome to the new tank factory, Commander."

Su Yan was in a daze for a while, and in the next second, he was already in a brand new place.

Instead, he was shocked.

Everything that catches the eye is high-tech!

It's like an underground construction site.

It also seems to be an extremely large drilling well, estimated to be at least a thousand meters wide, looking down, it is very bright.

There are countless giant cranes in the sky, and even various small machines that cannot be explained by common sense are flying.

This place is like a kingdom made of machines, every machine has a life-like existence.

And at the bottom of the deep well, there is a giant furnace that emits blazing light.

I don't know what is running inside, it looks like a furnace in hell.

"Buzz~~~"

This is, a faint humming sound appeared in Su Yan's ear.

Su Yan turned his head to look, and it turned out to be a small... bird?

This bird is not big, it looks as small as a finger.

wrong!

This is not a real bird!

It's a... mechanical bird!

A bird made entirely of mechanical parts.

Su Yan showed a smile and slowly stretched out his hand.

In the next second, the mechanical bird slowly flew to Su Yan's fingertips as if possessing spirituality.

It stayed on Su Yan's fingertips.

He even lightly pecked Su Yan's fingertips twice with his not-so-sharp beak.

"Huh? Could it be that machines are also spiritual?"

Su Yan made his own guess.

The red alert system is not as simple as it seems on the surface, and it will be reflected after entering this second-level tank factory.

…… Ask for flowers………

"Boom~~~"

There was another strong roar.

The voice came from the top of the head, and then Su Yan looked up, and then his eyes widened slightly.

In the originally enclosed space, a huge portal suddenly appeared at the top.

Then three Kirov airships appeared in the portal.

The size of the Kirov airship is already very large, and its size is even larger than the original tank factory.

In fact, Su Yan was a little confused before. The original tank factory was much smaller than the Kirov, so how could he produce equipment as large as the Kirov airship?

Now Su Yan may have some clarity in his heart.

These chariot factories are definitely not directly manufactured, they should be manufactured somewhere, and then sent over through time and space.

After the Kirov airship entered the tank factory, the tank factory started working quickly.

A large number of mechanical arms protrude directly from the inside of the deep well, and the steam is filled... It looks full of science fiction, but it gives people the illusion of the steam age in the 19th century

It seems to be... the fusion of super-generation technology and modern technology creates a strong sense of illusion.

Su Yan:

Su Yan looked at the Kirov airship that was being transformed, his eyes narrowed slightly, and then he turned and left.

After seeing the improved tank factory, he now yearns for the third-level Kirov airship even more.

What kind of air weapon is it with cannons and super weapons?
