One Punch Star Annihilation

Bang! Bang! Bang...

There was a constant explosion in the sky.

Fang Yuan continued to test the lightning vortex ring and was familiar with this terrifying thrust.

"This thrust is greater than I thought. If it hadn't absorbed the etheric dragon blood, I wouldn't have been able to bear it." Fang Yuan was testing while communicating with Professor Yang Yuping on the ground.

"Of course, if the lightning vortex ring is compressed to the limit, it will be a small nuclear explosion. Of course, the compression has not reached the level of a nuclear explosion, but you can also imagine how powerful this is. Simply put, if you don’t The protective layer of strong interaction force cannot withstand this thrust at the first stage." Yang Yuping replied.

Bang!

Fang Yuan adjusted the thrust direction of the lightning vortex ring by adjusting the position of his feet, using that powerful explosive thrust to make lightning turns in the air.

At the moment when the lightning vortex ring exploded, it was like stepping on the ground with "lightning speed", as if stepping on the physical ground.

After getting familiar with the advancement of the lightning vortex ring, Fang Yuan began to use the lightning vortex ring on his feet.

Finally, relying on the lightning vortex ring, achieved the effect of running in the air.

"Now try to see if you can rush to the stratosphere." Yang Yuping commanded.

Fang Yuan turned around, facing the sky, and a lightning vortex ring erupted.

Bang!

There was a burst of lightning, and the "Black Dragon" shot straight into the sky like a rocket.

It only took 25 seconds to rush out of a distance of 15 kilometers, break through the troposphere, and enter the stratosphere.

"I have reached the troposphere, and I plan to continue rushing upwards and see through the ozone layer." Fang Yuan asked actively.

"Yes, but pay attention to the oxygen supply situation. Once hypoxia occurs, return immediately." Yang Yuping agreed to this request, and then ordered.

"Ok."

Fang Yuan continued to explode the lightning vortex ring, sprinting upward, and instantly penetrated the ozone layer, reaching a height of 30 kilometers above the ground.

Flying outside the ozone layer, looking at the clouds below, it feels amazing.

Under normal circumstances, ordinary aircraft will only fly at a distance of 10 kilometers from the ground, and rarely exceed 10 kilometers.

Fang Yuan looked up at the sky, and suddenly wanted to try the limit, so he asked, "Can I fly out of the atmosphere and try it?"

"It's better not. The Black Dragon Battle Armor has not been tested in this area, and if it flies out of the atmosphere, there will be hypoxia. Although the suit has an oxygen supply system,..." Yang Yuping did not agree with this proposal.

"Has General Red Dragon flew out of the atmosphere?" Fang Yuan asked again.

"This..." Yang Yuping was speechless for a while.

Admiral Rod took the conversation and replied: "Flyed out."

Fang Yuan thought for a while and said, "According to the power principle of the lightning vortex ring, it can actually fly in space, right?"

"It is true in theory, but this is the first test of the Black Dragon Armor. There are still many areas that need to be optimized and perfected. Don't do such a dangerous move..."

Yang Yuping expressed his opposition and took the Red Dragon Battlegear as an example: "The Dragon Series Battlegear is not shaped all at once. The Red Dragon General Red Dragon Battlegear will be repaired and optimized every time the battle is over. The Black Dragon Battlegear, It also needs to go through this process to become a perfect suit."

"Actually, according to my ability, even if I drift in outer space, I have the ability to return to Earth. Even if I can't return, I can survive for a long time. In fact, there is no danger. Since I want to test, I should test the limit. Fang Yuan activated the lightning vortex ring and rushed out of the atmosphere.

Bang!

The speed shot again, sprinting out of the atmosphere.

People on the ground can no longer see the shadow of the Black Dragon Armor, and can only see Fang Yuan's location through the signal sent back from the electronic communication device.

"Young people are frizzy, how can they do such a dangerous thing in the first test?" Yang Yuping was a little annoyed.

According to his experimental habits, the first test should be conducted in the most stable manner, and such dangerous attempts must not be made.

"For him, the level of danger is not too high, and even if this kid is lost in outer space, someone can actually drag him back, so there is no need to worry too much." Admiral Rhode said with a smile.

The two are a lot of age, but their personalities are worlds apart.

The reason is also very simple.

Yang Yuping is a scientific researcher, and everything is focused on seeking stability.

Admiral Rhodes is a combatant and will never lack adventurous spirit.

Therefore, if there is no order from a high-level general, he will test the Black Dragon Armor instead, and he may also want to fly out of the atmosphere.

...

After 30 seconds, Fang Yuan rushed out of the troposphere and entered the middle layer.

After 50 seconds, Fang Yuan rushed out of the middle layer and entered the ionosphere, 100 kilometers above the ground.

After 20 minutes, Fang Yuan rushed out of the ionosphere and entered the outermost layer of the atmosphere, 800 kilometers from the ground.

After another 5 minutes, Fang Yuan rushed out of the atmosphere and entered space, 1,000 kilometers from the ground.

In fact, 99% of the atmosphere is within 100 kilometers, and the ionospheric atmosphere is very small. If it is not so strict, it can actually be regarded as space.

Moreover, there are already satellites 300 kilometers from the ground.

"Okay, you can go to that position. If you fly further, you will escape from the earth and come back soon. If you reach the escape speed and the lightning vortex ring engine is damaged, you really can't come back."

Yang Yuping's eager voice came from the intercom, and his anxiety could be heard in the voice.

Fang Yuan was in space, and he could already see the satellites with the naked eye, which felt very strange.

"Quickly check the situation of the Black Dragon Battle Armor, and come back after playing enough." Yang Yuping kept urging.

"Okay, I see, now the suit is intact, there is no problem."

Fang Yuan replied, and suddenly thought of another idea, saying: "Professor, how about I test the limit speed and see what speed I can reach from diving down from space."

"Can you return to the ground first?" Yang Yuping was really exhausted by Fang Yuan's whim.

"Actually, I don't think it's a big deal even at the limit speed. Try it." Fang Yuan suggested.

"I don't agree, don't you try?" Yang Yuping already felt a little weak.

"Then I will start."

Fang Yuan started to start the lightning vortex ring engine and dived towards the ground.

Under the dual action of engine thrust and earth's gravity, the speed began to soar, breaking the speed of sound in an instant.

However, breaking through the speed of sound is only the beginning.

The speed continues to soar, Mach 1, Mach 2, Mach 3...

When Yang Yuping and the researchers next to them saw the speed displayed on the communication device, they all swallowed involuntarily.

"Mach 4, it seems to be accelerating." Da Liu was a little excited.

Yang Yuping hurriedly reminded: "If you think about the temperature of your suit, if it becomes unbearable, stop immediately."

This speed is almost the same as that of an intercontinental missile. If this continues, the temperature generated by friction with the air can even exceed a thousand degrees.
