On the System Interface.
Su Fei noticed a line of information:
[Maximum flying speed: 3.4 kilometers per second (10 times the speed of sound)]
Su Fei had never flown at such a high speed before. The fastest he had tried was only three times the speed of sound.
Therefore, the system should be displaying the theoretical value.
After advancing to 1-star planetary state, one could theoretically increase their speed to 10 times the speed of sound.
Su Fei decided to give it a try.
He was now twenty-five thousand meters in the air.
There was little air here, and there was almost no water vapor.
However, as far as his eyes could see, it was a faint blue color.
This blue gas was the oxygen that protected the Earth!
Su Fei could smell a strong fishy smell. This was the smell of oxygen.
It can absorb most of the violet radiation and protect the earth.
However, this kind of thing was also harmful to the human body.
When the concentration was too high, it would seriously affect the human body's respiratory system, causing breathing difficulties, which could be fatal in serious cases.
Su Fei's current position was:
It was the place with the highest concentration of oxygen on Earth, the oxygen layer.
He felt a little suffocated.
Although it was the ability to control turtle breath,
However, the oxygen here was extremely scarce, and the concentration of oxygen was very high.
Therefore, Su Fei also felt a little uncomfortable.
Fortunately, his evolution ability was very powerful.
One second, two seconds, three seconds…
Ten seconds later!
Su Fei had completed his evolution and adapted to the atmosphere.
At this moment, his breathing rate had already reached a terrifying rate of once an hour.
His heart rate was also one beat per hour!
His reliance on oxygen was already very weak, almost equal to zero.
After adjusting his body condition,
Su Fei did not stay in the atmosphere for long.
Instead, it began to accelerate and fly higher!
One time the speed of sound…Two times the speed of sound…Three times the speed of sound…
Su Fei's speed became faster and faster.
When it reached five times the speed of sound,
He spread his ice wings behind his back to accelerate further!
Six times the speed of sound…Seven times the speed of sound…Nine times the speed of sound…
Ten times the speed of sound!
In three seconds,
Su Fei completed the acceleration from zero to ten times the speed of sound!
10 times the speed of sound was 3.4 kilometers per second!
This speed was still very terrifying on Earth.
It was equivalent to running ten laps around the football field in one second.
After accelerating, Su Fei only took two seconds to fly out of the atmospheric layer.
It reached a height of 30,000 meters!
After crossing the atmospheric layer,
Su Fei did not slow down.
Still maintaining ten times the speed of sound, he rushed up into the sky.
35,000 meters…
Forty thousand meters…
45,000 meters…
Fifty thousand meters…
Fifty-five thousand meters!
In less than ten seconds…
Su Fei arrived at an altitude of 55,000 meters.
This was another critical point!
55,000 meters below was the stratosphere.
In the stratosphere, the air mainly moved horizontally, and the vertical mixing of the air was obviously weakened. Therefore, compared to the troposphere 20,000 meters below, it was much more stable.
Furthermore, there was very little water vapor and dust here. The weather was clear and the atmosphere was extremely transparent.
Therefore, Su Fei's journey through the stratosphere was very smooth and did not encounter any difficulties.
Starting from 55,000 meters, they would first have to pass through the middle layer.
The air in the middle layer was extremely thin!
The temperature was also extremely low, reaching-100 degrees Celsius.
However, this was no longer a problem for Su Fei.
The Turtle Breathing ability could help him get rid of his reliance on air and oxygen.
He was wearing an ice armor, which was extremely cold.
Su Fei's skin had long adapted to this low temperature environment.
Even a temperature of-100 ° C would not affect him.
Su Fei continued to charge upwards!
60,000 meters…
70,000 meters…
80,000 meters…
Eighty-five thousand meters!
After nearly ten seconds,
Su Fei reached an altitude of 85,000 meters!
This place was another threshold!
'Cause beyond here,
They would undergo a very severe test:
Radiation!
In other words, the sun's violet rays and cosmic rays.
The air here was basically exposed to the background of the universe.
Therefore, it will be directly affected by the violet rays and cosmic rays, producing an ionised gas.
The temperature of the air would be extremely high, reaching more than a thousand degrees!
When an astronaut was in this kind of environment, if he didn't wear protective clothing,
Then his skin would be burned by the ultra-violet rays and radiation.
The blood, saliva, and so on in his body…would boil!
In less than two minutes, his body would explode.
Even his bones might not be left behind!
What worried Su Fei the most was:
It's the cosmic rays themselves, which cause radioactive damage,
One had to know that the reason why the atomic bomb explosion was so terrifying was that
It wasn't because of how much it could destroy when it exploded.
It was because it was radioactive!
Destroying the ecosystem, causing permanent fatal damage to the human body, and even inheriting it!
Human cells and genes would mutate uncontrollably under the radiation!
Su Fei's evolution speed was trillions of times faster.
Without a doubt, it would speed up the mutation process!
Therefore, Su Fei was still very concerned about the radiation environment above him.
He did not dare to be careless.
Even if his vitality was very tenacious, he could not court death.
When it was time to be cautious, he had to be more cautious.
Su Fei paused his flight.
He changed ten times the speed of sound to one meter per second.
Although flying at ten times the speed of sound was very refreshing,
However, in such a dangerous situation, it was still better to slowly fly up and adapt.
He wanted to familiarize himself with cosmic rays.
He couldn't take too big a step.
From 25,000 meters to 85,000 meters, Su Fei advanced triumphantly.
Next, he floated up one meter at a time.
Su Fei observed and felt his surroundings…
At this moment…
On the ground,
His wife, Yun Xi, had already landed at Yang Cheng Airport.
Originally, Yang Cheng Airport was a plain airport that was very close to the sea level.
But now, with the sea level dropping by more than 3,000 meters,
Yang Cheng Airport had become a high-altitude airport.
Yun Xi was wearing high heels and a long black dress, outlining her beautiful figure.
She tied her long hair into a bun and tied it on top of her head. She was charming and full of intellectual beauty.
He walked out of the plane.
He felt dizzy from the lack of oxygen.
Yun Xi took a few minutes to get used to it.
Her genes were also very strong, and her body's adaptability was very strong.
Without much rest, Yun Xi decided to head to the Eastern Academy of Sciences immediately.
Several military vehicles came to pick her up personally, and there were even police cars to clear the way.
After arriving at the Eastern Academy of Sciences,
Yun Xi received a warm welcome.
In her previous life, she was second only to Su Fei in scientific research.
"Professor Yun, our Eastern Academy of Sciences is waiting for you to cooperate with us to develop the gene serum.”
"We have something that belongs to Chief Su here. You must be very interested.”
