"Wenchang, the somersault cloud is flying normally!"

"Beijing, tracking is normal!"

As the sound of the various systems on the ground gradually faded away, Yang Yi sat in the cockpit of the head of the rapidly rising "somersault cloud", the huge gravitational acceleration overload made him a little out of breath, although the spacesuit already had a noise shielding function, but the eardrum was still vibrated by the huge roar of the nuclear fusion engine.

Just a few tens of seconds later, the "somersault cloud" had already flown over the Pacific Ocean, 500 kilometers above the earth, at a speed close to 8,000 kilometers per hour.

Yang Yi had clearly felt the weakening of the earth's gravity, and his whole body began to float in his seat.

"The gravity centrifuge is activated, and an artificial gravity field is generated." Almost as soon as Yang Yi realized the disappearance of the earth's gravity, a gentle female prompt voice in the main control system of the spacecraft, with the start of the gravity centrifuge, the gravity field in the cabin returned to normal levels.

At the same time as the artificial gravity was restored, a new round of acceleration had begun, and the greater acceleration suddenly acted on Yang Yi's body when it was overloaded, Yang Yi's whole body sank, and a boulder was suddenly pressed on his chest, his head was swollen and painful, and his ears were ringing and dazzling. The acceleration overload was close to the limit that Yang Yi's body could bear.

"Gravity acceleration has reached the limit of the human body, start the gravity overload balancing engine!"

Just when Yang Yi was about to faint due to the acceleration overload of the fusion anti-gravity engine, a gentle female prompt voice from the central control system sounded in his ears.

Yang Yi's body was light, and he was instantly relieved, and it was only at this time that Yang Yi passed the dangerous period of the spaceship's launch.

At this time, the spacecraft was close to its initial design speed of 300 kilometers per second, and it was 50,000 kilometers above the ground.

From now on, Yang Yi's body can no longer feel the discomfort caused by gravitational acceleration, and the blue earth outside the dazzling window is gradually moving away from him, and in front of him is the black canopy and the sun hanging on the black canopy like a bright lamp.

Yang Yi glanced at the black starry sky in front of him and let out a long sigh, it was only now that he and the "somersault cloud" really started their journey in the universe.

Yang Yi stood up from the driver's seat and prepared to change out of the heavy space suit on his body.

"Good evening, Yang Yi, welcome to space, I am your astronaut assistant Han Weiwei, and I will accompany you as a spaceship attendant for the rest of the 'somersault Cloud' to Proxima centauri 2,150 years ago." The moment Yang Yi got up, a sweet-looking slender girl wearing a logo blue overalls walked over.

Yang Yi glanced at the gentle face of the beautiful girl in front of her, and her expression was a little uncomfortable. This is the latest generation of semi-biochemical robots developed by Robotics for spaceships.

After nearly half a century of rapid development, artificial intelligence has undergone dozens of generations of product updates, and the latest generation of semi-biochemical robots looks almost indistinguishable from humans.

Nowadays, most of the existing work of human beings can be completed by highly intelligent robots, and the memory of Han Weiwei, the robot on the "somersault cloud", is customized for Yang Yi's task.

"Thank you!" In front of a robot, Yang Yi naturally didn't look too restrained, he took off the spacesuit on his body and handed it to the robot Han Weiwei, and said casually.

"No thanks, always at your service!" The robot Han Weiwei pushed the shelf where the spacesuit was placed, put Yang Yi's spacesuit on it, and turned around and walked towards the spacecraft's living area.

However, what people on the earth, including Yang Yi, who had just embarked on a space voyage, and 100 memories on the earth did not know was that every progress in earth science and technology was under the surveillance of a highly developed planet in the universe, and Yang Yi and the "somersault cloud" that was sailing in space were also under their surveillance.

Eight p.m. during interstellar voyage time.

Yang Yi took back his somewhat tired gaze from the black cosmic starry sky outside the "somersault cloud" dazzle window, checked the parameters of the spacecraft according to the spacecraft's autopilot flight log, and after confirming that all the indicators were normal and accurate, he glanced back at the direction of the earth outside the dazzle window, this will be the last night before hibernation.

After tonight, the "Somersaulting Cloud" ecosystem will go into hibernation mode, in energy-saving mode for 2140 years in spaceflight, and will not be activated until ten years before he wakes up. Yang Yi, on the other hand, will spend 21.4 Earth Centuries in a dormant chamber, during which the spacecraft will be autonomous, controlled by the robot Han Weiwei.

Yang Yi walked to the living area in the middle of the spaceship, these familiar bedrooms, kitchens, bathrooms, sports and fitness venues, and entertainment facilities made Yang Yi's lonely heart feel a little warm, and he couldn't help but feel a trace of tiredness in his heart.

This is the most relaxing night since joining the "somersault cloud" program, and now except for the time shown in the spacecraft system log, for Yang Yi, who is already flying in space, there is not much difference between day and night.

"Mr. Yang Yi, do you need dinner?" The robot beauty Han Weiwei saw Yang Yi walk in, walked over with light steps and said with a smile.

"No, I'd better take a hot shower than dinner." Yang Yi glanced at Han Weiwei, who was standing in front of her, and said with a hint of mockery.

"Mr. Yang Yi, I still suggest that you eat first." The beautiful robot Han Weiwei is still facing the suggestion of a smile.

"You'd better take care of yourself, you don't have to worry about what to do first." Yang Yi ignored the robot, took out a close-fitting soft spacesuit from the closet, and walked towards the bathroom in the living area.

This is the last bath before hibernation, and the next time, Yang Yi is ready to spend the rest of the time in hibernation.

Maybe he will wake up again, and the solar system will become an eternal memory.

Half an hour later, Yang Yi walked out of the bathroom and came to the hibernation cabin.

The milky white rectangular hibernation cabin flashed orange lights, and Yang Yi's eyes stared at the display interface on the hibernation cabin for identification.

"Toot!" The interface of the hibernation module slowly opens after displaying the words "Authentication Completed".

Yang Yi walked into the hibernation cabin and lay down slowly, and a comfortable and sleepy coolness slowly surged over his body, making Yang Yi feel like he wanted to fall asleep.

Yang Yi felt that his eyelids were extremely heavy, and he silently counted down from a hundred in his heart. After barely sixty, the hypnotic effect of the hibernation system was fully exerted, and Yang Yi fell into a deep sleep with a calm face. Embark on your first 21.4-century Earth hibernation on the somersault to Centauri.

Everything on Earth seems to be in perfect shape, and the sun still rises in the east and sets in the west every day.

The sensation caused by the launch of the first nuclear fusion ship of the "somersault cloud" in the world gradually faded into the distance of space and time faded as Yang Yi piloted the spacecraft. With the exception of the scientists in charge of the "Spreading Cloud" project, the headlines have been replaced by an endless stream of news.

The development of earth science and technology seems to have been a shot in the arm because of the successful use of nuclear fusion anti-gravity engines, and for a time all kinds of whimsical inventions continued to come out, and in just a few years, there was an explosive growth.

At a conference on space development held at the United Nations headquarters, China took the lead in drafting and first signing the "Intraplanetary Development Initiative" for the purpose of exploiting the resources of other planets in the solar system, which was supported by most countries, including the permanent members of the United Nations Security Council.

At the same time, the solar system's interstellar joint fleet, powered by nuclear fusion, has begun to be designed and will soon be manufactured as the hardware of this initiative.

What Yang Yi, who has entered hibernation, and the high-spirited earth humans don't know is that under the surface of everything is normal, there is an uneasy fact, the Maltese civilization of Proxima Centauri, the terminal star galaxy of the "somersault cloud" voyage, has just gone through the third big explosion of science and technology, breaking free from the development restrictions of low-level civilization planets in the universe, and leaping into the fourth-level medium-civilization planet, with the manufacturing capacity of one-tenth of the speed of light interstellar battleships.

And use stellar energy to create a certain scale of small and medium-scale artificial wormholes, using the principle of wormhole space folding, some kind of invisible monitoring system is deployed near the earth's orbit, every progress of earth science and technology, unconsciously under the close monitoring of the Maltese.

The predicament was caused by a physical experiment by Chinese scientists decades ago.
