The UFO rose very quickly, and in the blink of an eye, it rose from the secret factory area of Ruicheng to an altitude of 3,000 meters.

This altitude is a normal cruising altitude for propeller aircraft during World War II, but it is not low for civil aircraft in this year.

Because most of today's civil aircraft and fighter jets will cruise at the top of the troposphere at 10,000 meters.

After all, at the top of the troposphere of 10,000 meters, there is relatively little wind resistance and convection, and it is safer and more fuel-efficient to cruise.

The reason why Chen Hao controlled the UFO to fly to an altitude of 3,000 meters and paused, in fact, was also to test the stealth performance of this self-made UFO, as well as the propulsion power of the [Electromagnetic Levitation Module] and the [LIPS-200 Ion Rocket].

"Climbed 3,000 meters in 5 seconds?"

"Almost 600 meters per second?"

"This is only a 5% acceleration strategy!"

"Damn! I look like I've made something terrible. Chen Hao stared at the parameters of the LCD dashboard, and said to himself with some old gods in his mouth.

You must know that in order to ensure the stability of the fuselage, the climb speed of ordinary civil aircraft will be controlled at about 10 m/s. The climb speed of the jet fighter at the power point can reach more than 300 meters per second.

But what the hell is it that climbed 3,000 meters in 5 seconds?

This is the initial start from the surface, and it almost flies into the sky in the blink of an eye!

Even rockets and space shuttles with higher power dare not say that they can rush to an altitude of 3,000 meters in 5 seconds after takeoff.

Because there is always a process for the acceleration of the aircraft, the more bulky the aircraft, the initial take-off speed will not be too fast.

According to the instrument display of this UFO, the climb speed of 500 meters per second is not its limit at all, and at most it exerts 5% of the power of 8 ionized rockets.

As for the [Domestic Stealth Fighter Paint (Super Version)] sprayed outside the UFO, it is even more terrifying!

Because according to the radar system on the dashboard, since the black UFO rose into the air, no radar or satellite detection radio waves have been able to contact the fuselage.

Those radar bands, which are invisible to the naked eye, are automatically absorbed and filtered out almost as soon as they get close to this UFO.

Fuck it!

Nearly 100% radar stealth!

As long as it is not captured by the naked eye or optical cameras, the UFO developed by the turtle can be firmly suspended above the human head like a transparent person.

And there is no light at an altitude of 3000 meters, and with the black coat of this stealth coat, it is close to 99.99% stealth.

The remaining 0.01% may be spotted by a lucky astronomer with a space telescope, or a large bird that is bored flying in the middle of the night.

Compared with Chen Hao's stunned face, Zhang Sanfeng and other bull-nosed veterans at this moment are meditating and refining qi in the cockpit of a UFO.

For these bull noses who are bent on cultivating immortals, no matter how good the performance of this UFO is, it is just a vehicle to send them to Mars.

Especially in the eyes of Zhang Sanfeng, an old antique, the value of this big frisbee made of iron will definitely not be much stronger than the ox carts and horse-drawn carts used by the common people in the Ming Dynasty.

However, the two young Taoist priests who had lived in the world were looking around in the UFO cabin with a curious face, and kept sighing at the terrifying research and development capabilities of this [future technology].

It's a UFO!

Which country on earth can make the earth?

Even the most advanced fifth-generation fighter is scum in front of this UFO.

Why scum?

Because after Chen Hao finished testing the stability and stealth performance of the body, his brain suddenly became hot and directly pushed the power of the power system to 100%.

Boy!

The original 600 m/s climb speed suddenly skyrocketed to nearly 20 times, directly doubling to Mach 35, which is almost an incredible speed.

What is the concept of Mach 35?

That's 35 times the speed of sound!

If you fly at this speed, the straight-line distance from the Demon Capital to the Imperial Capital is estimated to take only 100 seconds to fly. It takes nearly 2 hours to change to an ordinary civil airplane, and 6 hours if you take a high-speed train.

This shows how terrifying this speed is!

Of course, flying at hypersonic speeds puts a lot of pressure on the UFO fuselage.

Because once this speed is rested on any man-made aircraft, as long as the materials used in the aircraft are a little worse, it is guaranteed that you will immediately disintegrate in the air, or be ground into a reddish molten slurry by the air friction of the atmosphere.

As for those pilots hiding in the aircraft, it is estimated that they will be completely torn into a pulp by the G-value generated during the flight.

What is G-Value?

It is the overload force on the pilot's body when accelerating or decelerating.

You must know that the G value that ordinary pilots can withstand is about 5 G, and the best fighter pilots can withstand 9 to 10 Gs.

But even the fastest jet fighter on the planet can only reach about Mach 6.

Chen Hao came to Mach 35 all of a sudden, almost 5 times the limit speed, and this sudden burst of acceleration was an overload of nearly 50 Gs for the pilot and passengers in the UFO cabin.

Even the most awesome special pilots on the planet will be crushed into pieces of paper in minutes under this overload. But this overload force of nearly 50 Gs has nothing to do with Chen Hao and Zhang Sanfeng, a group of bull-nosed veterans!

Chen Hao is good, because of the relationship between the data system in his head, his whole body has long been as hard as iron.

Not to mention the flight overload of 50 Gs, even a small-yield nuclear weapon has been carried by this turtle himself.

On the contrary, it was the endurance of Zhang Sanfeng's group of bull-nosed veterans, but Chen Hao was surprised.

Because just when Chen Hao adjusted the flight power to the maximum, he subconsciously aimed at Zhang Sanfeng in the cabin. I saw that this white-haired bull-nosed old man actually had a cyan fluorescence on his body, and this layer of fluorescence then turned into a light mask, firmly protecting the disciples and grandchildren beside him. Obviously, he used some kind of exercise or magic weapon to easily withstand this terrifying overload force.

"it!"

"It's worthy of an old fairy, and there is still such a way to solve overload?"

"It seems that these old Taoist priests have never flown in outer space before. Chen Hao muttered in his heart, controlled the rudder, and pulled the UFO's flight altitude from 3,000 meters to a million meters above the ground.

Boy!

1,000 kilometers above the ground!

As long as Chen Hao continues to climb, he can easily get rid of the atmosphere and the earth's gravity, and go directly to the target's outer space of the earth.

It's just that Chen Hao didn't choose to continue climbing, but turned on the UFO's radar system and began to search for nearby radar satellites in the dashboard.
