Chapter 422 Waiting for the Resurrection

I saw Jiang Haotian again at the "Sick bay" filled with liquid steel cans. The low temperature liquid nitrogen around him made him look really not dead, but frozen.

The nurse who received me was an american girl with blonde hair and blue eyes. Today, I realized that the nurse was not wearing any makeup or gorgeous clothes. She was wearing a white hat and white clothes, but she had a different kind of beauty.

She was a little tall, only slightly slimmer, with large beautiful eyes and a smile on her white and red face.

I suddenly thought of a question, so I asked, "If you freeze the human body, won't the blood in the human body freeze?"

I couldn't help but say my own question, and found that Jiang Lai was looking at me with a confused look, as if she didn't know.

However, the foreign nurse was not a foodie, so she used translation software to say, "Dear sir, from the basic laws of physics and chemistry, we can deduce that it usually takes - 120 degrees celsius to store animal cells for a long time. Of course - 196 degrees celsius is better. At this temperature, all chemical processes almost stop completely, unless the storage time is measured by geological time. At this point, the only damage is from high energy radiation, but it usually takes hundreds of years before it becomes a real threat. After decades of research, scientists discovered that there was an obvious danger zone in freezing and reviving animal cells. The damage mainly occurred in this zone. How to get through this dangerous temperature range and reach - 120 degrees celsius safely is the focus of the research. Let's first look at what might happen when freezing animal cells.

Freezing of cells usually begins at - 5 degrees celsius, because the liquid inside and outside the cell is a salt solution. When the liquid inside and outside the cell enters the supercooling state, the liquid outside the cell freezes first, which is basically composed of water without salt. If the temperature drops too fast, the ice may break through the cell membrane and enter the cell, or the liquid inside the cell quickly begins to freeze. These rapidly growing ice crystals will almost certainly cause serious damage to the cell membrane, and the hope of recovery will end. So where did the ability of cold-resistant creatures come from? The answer is the synthesis of glycerol anti-freeze substances.

The freezing point of the glycerol solution was very low, and when the outside of the cell began to freeze, the temperature of the inside of the cell was still above the freezing point. Along with the process of freezing, the salt concentration of the outer liquid began to rise. Under the influence of infiltration, the cell began to dehydrate, and the speed was different because of the different factors such as cell membrane. The contraction of the cell volume could avoid the ice crystals outside the cell and further reduce the freezing point inside the cell. Therefore, most of the cells of these freezing resistant creatures were not really frozen under the low temperature of the natural environment, which effectively prevented the damage of ice crystals. The presence of these anti-freeze substances can also prevent damage caused by excessive dehydration and contraction of cells, and at the same time prevent the concentration of harmful substances from rising too high, slowing down the possible chemical damage. "

Because there are a lot of chemical, biological, and medical terms in it, thanks to the translation software, otherwise I, a level four english player, would never understand it.

In the end, the blonde nurse said, "The perfusing strategy is to use a gradient, that is, after the protective liquid enters the blood vessel, the concentration of the protective liquid in the blood is gradually increased, and accordingly, the temperature is gradually decreasing. The whole process passes through the freezing point of the water, and when the capillaries run, the protective agent penetrates into the cells and tissue fluid, which is equivalent to the process of dehydration. After replacing the water with the protective liquid, it will have the greatest protective effect."

My expression wasn't much better at the time. It must have been a blank look. I believe Jiang Lai wasn't much better, but we still underestimated this little nurse. She actually suggested that we apply to watch Jiang Haotian's frozen video.

"Honey, do you need to see it?" I asked weakly.

Jiang Lai nodded and actually agreed. After all, it was a big matter of whether her brother Jiang Haotian could come back to life or not. She wanted to see it, but she never dared to.

Then we were led to a place similar to a projection hall and began to wait for a long time. It seemed that the video needed to be applied to the leader of their place. The little nurse could not make the decision.

Finally, as we waited impatiently, a tall foreigner came in. He mumbled a foreign language and started playing the video.

Jiang Haotian, who was only 43 years old, lay on the bed and was in the stage of dying.

In the next room, two surgeons from the united states had been waiting for eight hours. In fact, they had been waiting for this moment since three days ago.

Two hours and thirty-two minutes later, Jiang Haotian died peacefully. The two american doctors immediately injected jiang haotian with anticoagulants, antibiotics, and anti-thrombotic drugs to prevent blood clotting, and used special equipment to press the heart to ensure that the blood continued to circulate.

Jiang Haotian's body was then placed in a wooden coffin filled with ice and quickly moved to the operating site, which took about an hour.

The next step is to perfuse. Because human cells contain a large amount of water, during freezing, water will solidify to form ice crystals, which are very easy to pierce cells and cause great harm. Therefore, the key point of freezing technology is to use a protective liquid with a lower freezing point and not easy to crystallize to replace water, so as to achieve the effect of dehydration.

American doctors first used diluted protective fluids to gradually replace the blood left in the body. Then, the instruments were used to open the common arteries and veins in the neck of the body, forming a circuit for the infusion of the liquid, and the protective fluid was injected.

The procedure would take a long time, and the doctor would gradually increase the concentration of the protective fluid and inject it into the head from the artery. When the concentration of the protective liquid in the human body reached the requirements for the preservation of the remains, the concentration of the protective liquid in the intravenous output was continuously monitored. When the concentration of the protective liquid was the same as the input concentration, it indicated that the water in the head had been completely replaced.

After more than four hours, the whole process needed to be completed at freezing temperatures close to zero degrees celsius. After that, the body needed to be cooled down further. The staff used dry ice at - 60 degrees celsius to gradually cool the body down, and eventually stored the body in an ice coffin at - 40 degrees celsius. At this point, the preliminary process of freezing the body was completed.

Next, Jiang Haotian's body will be sent to alcor's headquarters in Losangeles (one of the world's largest frozen human research institutions) under freezing conditions. The head of the body will be separated and stored in a special liquid nitrogen container at - 196 degrees celsius.

Over the years that followed, the staff would add liquid nitrogen on schedule to ensure that Jiang Haotian's head was preserved for a long time.


The videos were all edited, about ten minutes long, and a lot of content was omitted at a glance.

However, the video was meticulously made, marked in key areas, and there was one last sentence:

According to the optimistic alcor scientists, 50 years later, science and technology might be able to thaw Jiang Haotian's head and regenerate his body, that is, resurrect him.
