"Upgrade other facilities at the base!"

Strategic weapons are not in a hurry for the time being.

Upgrading these infrastructures is now a priority.

Just an advanced radar can detect 3,000 kilometers.

So, how terrifying would a higher-level radar be?

There are several other facilities that are equally helpful to him.

Shen Yi is very much looking forward to this.

"Yes, Master!"

Shen Ling responded.

The next moment, several prompts appeared in front of Shen Yi's eyes.

"You have deducted 30,000 units of iron, 20,000 units of copper, 3,000 units of psionic crystals, 500 of any C-grade material, and 300,000 energy points. The advanced radar has been upgraded. The upgrade time will take 45 minutes. The current countdown is 44:59."

"You have deducted 50,000 units of iron, 30,000 units of copper, 5,000 units of psionic crystals, 700 of any C-grade material, and 400,000 points of energy. The advanced machinery factory has begun to upgrade. The upgrade time will take 60 minutes. The current countdown is 59:59."

"You have deducted 10,000 units of iron, 8,000 units of copper, 1,000 units of psionic crystals, 300 of any C-grade material, and 100,000 points of energy. The advanced living factory starts to upgrade. The upgrade time will take 30 minutes. The current countdown is 29:59."

"You have deducted 20,000 units of iron, 15,000 units of copper, 3,000 units of psionic crystals, 400 of any C-grade material, and 200,000 points of energy. The intermediate-level energy mining equipment factory has been upgraded. The upgrade time will take 40 minutes, and the current countdown is 39:59."

...

This upgrade cost a lot.

The energy alone cost a million points.

If you let ordinary players pay such a huge amount of energy.

No matter how frugal they are, it will take more than half a year to do it.

Even, this is coupled with the efforts of their family members.

However, for Shen Yi, it didn't even have the qualification to make his eyelids wink.

However, this time the upgraded facilities lacked the Mechanical Technology Research Laboratory and the newly emerging Strategic Weapons Research Center.

Not that Shen Yi didn't want to upgrade them.

But if they want to upgrade, they must make a condition.

The Mechanical Technology Research Lab needs 100% progress, while the Strategic Weapons Research Center needs to unlock at least one strategic weapon.

If these conditions are not fulfilled, even if there are resources in hand, there is no way to upgrade.

Shen Yi immediately rubbed his hands excitedly after watching these facilities enter the upgrade.

"Shen Ling, let the survival base... no, it's the air carrier flying!"

He still has very high expectations for the performance of the air carrier.

"Yes, Master!"

Shen Ling responded.

Immediately, Shen Yi saw that the 16 small thrusters behind the air carrier in front of him, and the four super-large thrusters below, gradually lit up with blue flames.

The huge wind blows away all the surrounding sand and dust.

The impact range even reached tens of kilometers.

The nuclear power engine installed on the air carrier is much more powerful than the nuclear power engine on the earth.

It easily pushed the air carrier with a weight of hundreds of thousands of tons and lifted it into the air.

Now, Shen Yi has also figured out a reason.

That is the technology unlocked by the survival base, even if you look at the peak civilization of the planetary level.

That is definitely at the current level, the most advanced level.

Therefore, the nuclear power engine possessed by the air carrier is definitely a very mature technology.

At this time, Shen Ling's voice sounded in Shen Yi's ears: "Master, the helicarrier has been warmed up, the current limit speed is Mach 3, and the maximum flying altitude is 17,000 meters, please set the altitude of the helicarrier. with the goal."

"The speed is Mach 3?"

Shen Yi was a little surprised, this speed was even more powerful than the fifth-generation fighters on the earth.

At Mach 3, that's three times the speed of sound.

If it is calculated as the speed per hour, it is 3675km/m.

Moreover, Shen Yi is very satisfied with the maximum flight altitude of 17,000 meters.

This means that he can cruise directly 17 kilometers above the ground, which is much safer than on the ground.

As long as those monsters are not particularly sensitive, it is almost impossible to find him.

Don't look at the current speed of the air carrier.

It seems to be a little bit stronger than the fifth-generation fighter.

However, throwing away weight and talking about speed is hooliganism!

The air carrier is a behemoth that weighs hundreds of thousands of tons!

Even the largest aircraft carrier on earth is only a third of its size.

It is conceivable that such a terrifying body shape and a speed of Mach 3 are exaggerated.

"Cruise at maximum altitude, if the location... just go directly to the No. 2 Small Bio-Gene Research Institute!"

Shen Yi ordered in a deep voice.

He didn't particularly care about where he flew to.

He just wants to see how the performance of the air carrier is!

"Yes, Master!"

"Maximum altitude cruise, Target No. 2 Small Biogenetic Research Institute!"

Shen Ling repeated the destination that Shen Yi said.

The next moment, the aerospace carrier moved.

Boom!

Accompanied by a loud bang.

Four blue flames with a length of 100 meters were ejected from the four propulsion ports below.

Pushing the shape of the air carrier, it quickly climbed towards the high altitude.

1000 meters...

5000 meters....

10000 meters....

15000 meters...

17000 meters! ! !

The critical point altitude has been reached, where it has entered the atmosphere of the planet.

In just five seconds, the air carrier directly rose to a height of 17,000 kilometers.

This vertical climb speed is simply outrageous!

It displayed a movement speed that was completely inconsistent with its huge size.

If it were replaced with aerospace equipment on Earth, dare to rise up in a flat manner in five seconds.

I am afraid that it will be torn directly from the middle.

However, the material of the air carrier is extremely tough, and it has not been affected in the slightest.

And after ascending to the critical altitude of the helicarrier.

The four thick and long blue flames below slowly disappeared, and the upward thrust became suspended.

At the same time, the sixteen slightly smaller thrusters at the rear of the air carrier instantly burst into blue flames.

Bang!

It was followed by a sharp crackling sound.

A layer of white funnel-shaped fog instantly appeared around the air carrier.

However, this funnel-shaped mist only appeared for a moment, and it disappeared in the next second.

Amazingly, the air carrier broke the sound barrier in an instant, surpassing the limit of the speed of sound!
