It was an extremely cramped space, like a coffin, with limbs, body, and head tightly bound, and the whole body could not move.

Chu Tianjiang wanted to open his eyes, but he couldn't exert his strength.

There was something in the mouth, like a mask, and a tube in it that went all the way to the lungs. The buzzing sound in his ears made Chu Tianjiang unable to hear his breathing or his heartbeat. Thinking of what the girl said, Chu Tianjiang knew that his body was in a frozen state, so he had no breathing and no heartbeat. Because the brain is also in a frozen state, it is difficult to even think. For example, severe sleep deprivation, foggy thinking, and difficulty concentrating.

This is a frozen hibernation pod designed by Luo Jinyong and Melanie.

Chu Tianjiang tried to stay awake and didn't let himself fall asleep. Although the hibernation pod has an external opening function, it can also be opened from the inside. The control system of the hibernation chamber will automatically thaw after detecting the increase in the hibernators' brainwaves, allowing the hibernators to wake up.

It takes some time and requires strong enough willpower.

I don't know how long it has been, Chu Tianjiang felt that his mind was a little clearer, and he was able to carry out some more complex thoughts, indicating that the thawing procedure had been activated.

Compared to the freezing process of hibernation, the thawing of awakening is very slow.

Because the human body contains a lot of water, the cells are almost all water, and when the water is crystallized, the volume will expand, and it will also break the cell membrane, resulting in cell necrosis, so when hibernating, it is necessary to inject a liquid used to speed up the freezing speed into the body of the hibernator to shorten the freezing time, so that the water in the body can not form large particles of crystallization, so as to avoid the rapid expansion of the volume of water when crystallization.

This is the rapid freezing technique, and it is also the technical difficulty that must be overcome in freezing hibernation.

Defrosting, on the other hand, is a slower process. The main thing is that if it is thawed quickly, it needs to input enough energy in a very short period of time to form an energy focus, which produces high temperatures and causes necrosis of the cells that thaw first. Only by extending the thawing time, allowing the energy to be released smoothly, and keeping the temperature of the thawing site not too high at all times, can we ensure that the cells will not die during the thawing process.

This process takes at least a few hours.

Thawing starts from within, first rejuvenating the organs and restoring the vitality of the body, followed by organs and tissues such as muscles, skin, and bones.

After a long time, Chu Tianjiang finally opened his eyes.

It was pitch black, but after a few seconds, there was light.

It was very dazzling, and Chu Tianjiang immediately closed his eyes. Even when the eyes are obscured, the light is still strong. After a while, after the light dimmed a little and his pupils adjusted to the light, Chu Tianjiang opened his eyes again and saw the three-dimensional display screen located in front of his eyes.

This is a display controlled by pupil movements, which shows the details of the hibernation pod.

To Chu Tianjiang's surprise, the timetable had been cleared to zero, or it had stopped running, and the dates and times displayed in five segments were all zero.

How long has it been? Decades, hundreds, thousands, or tens of thousands of years?

Because the design life of the hibernation module is 100,000 years, it will certainly not exceed 100,000 years.

The problem is that no matter how many years have passed, humanity has missed a hundred years of self-salvation, the invaders have arrived, and they have conquered humanity.

What's next?

Just as Chu Tianjiang was thinking about this problem, a strong current entered Ti Nei, and he couldn't help but tremble. The current lasts for a very short time, followed by a second, third, ...... When the heart starts beating, the current disappears and the body comes to life.

Gradually, the rest of the body can be felt, and the limbs regain their strength.

When his toes were able to move, the panel of the hibernation cabin bounced open, and Chu Tianjiang tore off the pipes on his body and climbed up, and then he felt a strong feeling of suffocation. Chu Tianjiang rolled to the floor, leaned over, and spat out the liquid in his lungs. During hibernation, this fluid freezes first to protect the alveoli from breakdown during freezing. After taking the first breath of air, Chu Tianjiang's feeling was slightly better.

His limbs were moving, but he still didn't have much strength, and he could only crawl on the floor, gasping for air.

Although during hibernation, because the body is in a frozen state, except for a very small number of brain cells that are active, the other cells of the body have stopped metabolism and have not consumed sugar and protein in the body, but in long-term hibernation, those brain cells that are still active still consume a lot of nutrients. When Chu Tianjiang woke up, there was almost no sugar and fat in his body, and the protein was almost consumed.

At this time, Chu Tianjiang was extremely weak, almost like a newborn baby.

Crawling on the floor, Chu Tianjiang observed his surroundings.

It is a cylindrical enclosed room, about ten meters in diameter and three meters in height, with a hibernation pod in the center of the room, and a hemispherical protrusion on the floor and ceiling. At this time, the hibernation pod was suspended about half a meter above the ground, and it was very likely to be suspended in the center of the room before, but when Chu Tianjiang woke up, the suspension height was reduced by one meter.

The room has no doors, no windows, no vents and exhaust fans, it is completely airtight, and the ceiling, curved walls and floor are perfectly combined, and there are no gaps in sight, as if the whole room is made of a quick material, rather than a splicing of multiple materials.

The light was bright, it was cold, but there was no light source, as if the light was originally in this room and would never dissipate.

The temperature is around twenty-six degrees Celsius, but there is no air conditioning system and no significant air movement.

There is also the floor, which is not metal or plastic, it is a material that Chu Tianjiang has not seen before, and it feels extremely smooth to the touch. Chu Tianjiang tried to explore for a while and found a very interesting problem, that is, the material of the floor would change with the pressure it was subjected to. Gently place your hand on it, and the floor is extremely smooth, with almost no frictional resistance. With a little force, frictional resistance is created. The greater the pressure applied, the greater the frictional resistance generated. It is a smart material that microstructures itself by the induced pressure, creating the appropriate frictional resistance. There may be some other functions, but Chu Tianjiang has not yet discovered them.

It took a while for Chu Tianjiang to get up.

The body is very light, so light that Chu Tianjiang himself can't believe it.

Pulling the zipper on his chest, Chu Tianjiang found that he had lost a lot of weight, his originally strong chest muscles had already dried up, his abdomen was concave, and his abdominal muscles were almost touching his back. This didn't make Chu Tianjiang feel strange, hibernation for a long time consumed most of the sugar, fat and protein in the body, and it was strange that he was not thin. What really made Chu Tianjiang feel strange was that there seemed to be a force supporting him, so that he couldn't feel the weight of his body.

You must know that with Chu Tianjiang's physique, even if there are only bones left, there are dozens of catties.

Just as Chu Tianjiang stood up, the hibernation pod began to rise, and finally merged into the ceiling until it completely disappeared.

This time, Chu Tianjiang saw very clearly, the ceiling was not separated, and the hibernation cabin was connected to "enter" the ceiling. To put it more figuratively, the ceiling seems to be a liquid substance, and gravity is not going down, but upward, and the hibernation pod "sinks" into the ceiling.

Chu Tianjiang was surprised, but then thought of a possibility.

That is, the ceiling is not made of matter, but an energy field, just the reflected light that makes the ceiling look like a substance.

So, are floors and walls also energy fields?

In addition, the force that held Chu Tianjiang seemed to be generated by the energy field?

The strong feeling of hunger made Chu Tianjiang not have the heart to think about these problems. Although this "room" has a strong sci-fi flavor, he has returned to Earth.

Chu Tianjiang thought of something to eat, and then a cylindrical device "floated" in the center of the room.

It is indeed a device, but it is different from the equipment that Chu Tianjiang has seen before.

Chu Tianjiang walked over, walked around the device, and found a thumb-sized groove with "food" written in Chinese and English next to it.

Although he was very puzzled, driven by hunger, Chu Tianjiang put the thumb of his right hand on the groove.

The device emits some noises, which are distinctly mechanical. Chu Tianjiang immediately took two steps back, and then a crack appeared on the side of the device, and then bounced open.

It turned out to be a refrigerator!

Chu Tianjiang's eyes widened in surprise, and what popped open was the door, and inside was all kinds of food that had been frozen and was rapidly thawing. Judging from the white mist coming out, dry ice, that is, solid carbon dioxide, is used for refrigeration, and the food stored in it has also completed the hydrolysis and synthesis reaction when thawing, that is, it is "cooked", and it has become a cooked food that is easier to digest and absorb.

Obviously, this is still a microwave oven.

Surprise is surprise, Chu Tianjiang can't manage so much.

Although his intuition told him that this "room" was not necessarily built by humans, perhaps the work of the invaders, the guy who found the hibernation pod would not have waited for him to wake up, let alone provide him with food, so there was no need to worry about anything.

To worry, but also to fill your belly first.

The food is not very tasty, not a common food to be exact, but a synthetic food. For example, the piece of bacon looks like ham, but in fact it is just a mixture of protein, fat and sugar, and then made into the shape of ham, and it has no taste of ham in the mouth. There are also those drinks, which look like fruit juice, but in fact they are just mixed with various trace elements and vitamins needed by the human body in the water, as well as some sugar, and then dyed in some way to make it look like fruit juice, but in fact there is no taste of fruit juice at all.

Of course, what is the texture and taste of ham and juice, Chu Tianjiang has long forgotten.
