The communicator was also silent, waiting for Xue Shu to calm down, and then Wang Mian said: "Xue Shu, this time you go to the moon, I won't stop you, I only tell you two things: first, you must be careful in everything, be careful of Cybertrons, be careful of that kind of black bug." ”

"My province, Grandpa Wang!"

"Second, if it's possible, bring Xue Hanglin's body back, although he is an individual that you split from your father, but in fact, he is the same person as your father, the so-called burial of him in the earth, it is not good to bury him on our earth, the violent corpse moon is not good after all!"

"I will, I will!" Xue Jun clenched his fists, and his eyes flashed with determination!

"Let's go, Xue Jun!" Seeing that he had calmed down, Xiao Jin urged.

"Let's go!" Xue Jun nodded, his body was full of momentum, his tears were dry, and he said to Wang Mian: "Grandpa Wang, things on the earth will trouble you, no matter what happens, you must wait for me to come back!" ”

"Yes, you can go ahead, and we'll take care of the matter here!"

Wang Mian nodded solemnly and told repeatedly: "Remember, you must be careful, be careful!" ”

"Yes! I'm leaving, so be it! Xue Jun nodded, and was about to hang up the phone, but at this moment, only to hear Xiao Lu's voice come again: "Brother Xue Shu, wait, wait for me, take me!" ”

"Midori?" Xue Yu was stunned: "You better stay on the earth and make life energy with peace of mind, so you don't have to follow me!" ”

"Don't delay, don't delay, I can divide a descendant to go with you, and I can take care of you, in case you are injured, you can also let me help you heal!"

"That's right, it's still thoughtful you!"

"That's"

In the sky above Shaanxi, Xue Jun stood in the air, and Xiao Jin squatted on his shoulder, a man and a beast with a solemn face, staring at the sky, bright sparks bursting out of his eyes!

"Brother Xue Shu, I've hid it, and now I can fly!"

In the body guard alloy on the chest, there was a voice from Little Green, which was a child split by Little Green!

"Let's get started!"

Xue Yu took a deep breath, and the powerful power penetrated his whole body, and a low cry came out of his mouth, and the whole person was like a cannonball out of the boring, and it sprayed out with a bang.

His speed is getting faster and faster, faster and faster, like a rocket that is being launched, breaking through the atmosphere, rubbing against the atmosphere and making a terrifying scream, because the speed is too fast, a layer of transparent white air waves have formed all around him!

In just a few seconds, Xue Jun's speed broke through the speed of sound and reached Mach 1!

1 Mach 1 times the speed of sound 340 ms second!

"Rush!"

Xiao Jin was like being imprisoned on Xue Yu's shoulders, letting the wind rage, and the air was unmoved, and it shouted in a low voice: "Speed up!" Coo, accelerate, and break through the first cosmic speed in one go! ”

"Rush!"

The eagle strikes the sky, the fish soars to the shallow bottom, and all kinds of frost compete freely!

Xue Su's heart was full of pride, his eyes flashed with an astonishing light, and his speed increased again and again, reaching an astonishing level in just a few seconds.

Mach 2!

Mach 3!

Mach 4!

Mach 15!

"Into the troposphere!"

The troposphere, the lowest layer of the atmosphere, is close to the surface of the earth, its thickness is about 10 to 20 kilometers, clouds, fog, rain and other phenomena occur in this layer, water vapor is almost all present in this layer, and there are most of the solid impurities.

As the temperature continued to rise, the temperature became lower and lower, and the surface of Xue Jun's body, hair, and face formed a layer of ice, and the whole person was shining with a cold light under the sunlight.

Xue Fei's speed continued to climb, and finally reached an astonishing Mach 25!

25 times the speed of sound!

Almost in a second or two, Xue Yu broke through the 10-kilometer-thick troposphere and came to the stratosphere.

The stratosphere, about 30 kilometers thick, only took two or three seconds to break through the stratosphere and appear in the middle layer, which is about 50 to 85 kilometers above the earth's surface, where the air is already very thin, and the temperature is getting lower and lower, reaching minus **10 degrees.

Xue Yu's body surface was frozen into ice, and his whole person had turned into an ice sculpture, but he was still climbing rapidly, but the increase in speed became slow, and he tended to fly steadily upward.

Out of the mesosphere, up to the warm layer, about 100 to 800 kilometers above the Earth's surface, the air here has thinned to an outrageous level, and the temperature is relatively warm, but still surprisingly low.

Xue Jun's whole person completely turned into a solid ice cube, the surface was crystal clear, white as jade!

"Rush!"

Xue Yu's eyes were firm, and he also felt the ubiquitous strong atmospheric pressure, at such a speed, to challenge such a height, not only to withstand the terrifying air pressure, but also to withstand the astonishing low temperature.

The double challenges of low temperature and air pressure did not stop Xue Jun, he continued to rise, and finally after 13 minutes, he rose more than 6,400 kilometers, completely out of the scope of the atmosphere!

As soon as he rushed out of the atmosphere, Xue Jun's whole body felt light, as if he had broken free from some kind of cage, and as if he had flown out of the water, and the whole person was extremely relaxed.

"Haha, it's out of the atmosphere!"

Flying out of the atmosphere means that in addition to the gravitational force exerted by the earth, Xue Yu can no longer feel the atmospheric pressure, because his mass is too earth, the gravitational force given to him is almost negligible, so he rushed out of the atmosphere at a super high speed, and suddenly there was no resistance, and under the action of inertia, the whole person drew a long distance before stopping.

Completely out of Earth and into outer space!

Xue Yu was suspended in the air, he didn't feel any pressure, and his body was more relaxed than floating in the water, this is the vacuum state, that is, outer space!

"It's so beautiful!"

Xue Jun looked down and saw a blue planet under his feet, it was the earth, and his eyes were blurry, beautiful, so beautiful.

This kind of beauty is completely different from any beauty Xue Shu has seen, and this beauty is simply difficult to describe in words.

This is a majestic beauty, a beauty that people can feel from the depths of their souls, magnificent, majestic, vast, and vast

It is impossible to describe it in words, because it is impossible to describe it at all, and only when you really experience it can you feel the charm of this vastness and vastness.

This is the Earth!

"Whew"

Xue Yu exhaled a long breath of turbidity, his body was slightly uncomfortable, and after leaving the atmosphere, he was in a vacuum state, exposed, and needed to withstand the tests from the universe.

Terrifying low temperatures, ubiquitous cosmic rays, no oxygen, no atmospheric system, and more!

"No wonder only fourth-level lifeforms are qualified to survive in the universe, in such a harsh environment, ordinary planetary lifeforms can't bear it at all!"

Xue Yu was sure that a third-level life could live in outer space for a short time, while a third-level life would quickly freeze to death, or a blood vessel would burst or die of cardiac arrest.

In this state of no air pressure and no air, ordinary people's cells, blood vessels, and bodies can't stand it at all!

"The universe is so terrifying, it doesn't need to show any terrifying side at all, just with its size, it can make all the lower creatures desperate, just with its most basic environment, it can stop all the lower creatures!"

Xiao Jin said lightly: "Getting out of the home planet and adapting to the most basic environment of the universe is the most basic test of the universe for living beings, and this test is enough to discourage more than ninety percent of the creatures in the universe, and it is quite difficult for a civilization or a race to reach the second-level civilization or the emergence of a fourth-level lifeform!" ”

"It's difficult!"

Xue Yu only nodded: "But our earth is very lucky, not only has science and technology reached the second-level civilization, but also a lot of fourth-level life, according to Qingxu, the Yellow Emperor, Dharma, and Sanfeng Zhenren have all evolved into fourth-level lifeforms and left the earth!" ”

"Earth civilization will definitely shine more and more!"

"Definitely!"

"Let's go!"

"Let's go!"

Xue Yu took a deep look at the earth, found the direction of the moon, and ran wildly.

Without the earth's gravity and air resistance, it is easier to increase the speed, and all the work done is used to increase the speed, and in just a few seconds, Xue Jun's speed has reached Mach 20.

Accelerate accelerate, accelerate all the time!

Generally speaking, in outer space, it can be accelerated indefinitely, but Xue Yu no longer accelerates when he accelerates to Mach 30, but flies to the moon at a constant speed of Mach 30 according to inertia.

Interstellar flight, generally inertial flight!

On the one hand, this is done to save fuel, and on the other hand, after flying at a constant speed of inertia, the interior of the spacecraft is stationary, and the astronauts do not feel any force, just like staying on Earth and staying in a laboratory.

And Xue Yu chose inertial flight, naturally not to save fuel, but too lazy to accelerate, the speed of Mach 30 is 10,200 meters per second, 102 kilometers per second!

That's a speed, that's enough!

After flying at a constant speed, Xue Fei turned his head to look at the starry sky of the universe, admiring the scenery of the universe, in general, outer space seemed very monotonous, dim and dark, if it weren't for Xue Fei's amazing eyesight, he could see the scene in the distance around him, and he really couldn't stand such a scene.

Monotony!

I have to admit that the cosmic star space is too monotonous, and this is only the interior of the solar system, the interior of the earth and moon systems, and this bit of space is quite monotonous.

Needless to say, further afield!

Xue Yu also found that in the "Earth-Moon" celestial system, there are not only the two celestial bodies of the Moon and the Earth, but also some asteroids, that is, meteorites, which fly around the Earth and act as satellites of the Earth.

Fly all the way, enjoy all the way!

After 10 hours of flying at a constant speed, Xue Jun finally reached the lunar orbit, and after a frantic deceleration, he came to the sky above the moon!

At this time, Xue Jun didn't know if he had fallen into the surveillance of the Cybertrons, so for the sake of safety, he simply escaped directly into the space mezzanine and landed secretly.
