Sanqing Headquarters, Nano Laboratory.

At midnight, the lights on the entire floor were turned off.

In the darkness and silence, only one room was still brightly lit.

Xue Shen was standing in front of the workbench, staring nervously at the instruments in front of him, as if waiting for something.

Five minutes later, the machine buzzed and flashed green.

A plastic bottle below was quickly filled with a colorless and odorless transparent liquid.

He picked it up carefully, with a happy look on his face.

"It's finally done. This is the result of my three months of research, perfluorocarbon globin nanoemulsion."

"A spiked version of artificial blood."

During these months of research, he painstakingly improved the structure of perfluorocarbon and created a new molecule with a high oxygen carrying capacity.

Not only that, he also combined this molecule with globin to achieve the effect of transporting oxygen in human blood.

Human hemoglobin is mainly composed of globin and heme.

Among them, heme is similar to a compartment and is used to store and exchange oxygen molecules.

Globin is like a coupler connecting the train's power system and carriages, tightly binding the oxygen-laden hemoglobin together for efficient oxygen transportation.

However, unlike the long flat structure train in reality, this oxygen-carrying train is transported in liquid, so it has an efficient three-dimensional space folding structure.

It is like a honeycomb, with a dense hole structure. Oxygen molecules are densely embedded in the recessed heme from the inside out. They are tightly bundled together by globin and transported throughout the body in the blood.

Globin is like a diligent blood coachman, with large space, strong ability, and very hardworking and uncomplaining.

Xue Shen would naturally not let go of such a ready-made worker.

So we took advantage of the function of globin, replaced the heme with a perfluorocarbon compound molecule, and also improved the structure, changing it from a tetramer to a hexamer, making it more efficient and with higher space utilization.

Under such transformation, the same size has more perfect performance.

The new oxygen-carrying protein has a higher and faster ability to bind oxygen, and can also quickly release oxygen under designated circumstances, and can transport oxygen in the blood in the most efficient manner.

One nanoparticle can carry 9 billion oxygen molecules and carbon dioxide molecules, 200 times the amount carried by ordinary red blood cells.

It is also safe and non-toxic. It can be naturally decomposed in the human body within 24 hours and excreted from the body without causing any damage to the human body.

The speed of blood oxygen exchange and transmission determines the speed of human physiological reaction. The use of this kind of nano artificial blood will bring powerful explosive power and endurance to the human body.

And this is also the result Xue Shen wants.

He carefully held the jar of nano-artificial blood in his hand, and he couldn't help but feel excited and excited.

I can't wait to take a tube for myself right away and experience the feeling of flying.

Obviously, this is impossible.

Without animal experiments, the perfect performance parameters are nothing more than paper data.

Even for safety reasons, he had to conduct a few experiments on mice to verify the results before proceeding.

Xue Shen first injected pure oxygen into the nano-artificial blood solution to fully combine with oxygen molecules.

Then he found a squeaking white mouse, took out a syringe, and injected 1 ml of nano-artificial blood into the mouse's blood vessels.

Finally, he threw the mouse into a sealed glass tank filled with water and began to record the survival time of the mouse.

"Generally speaking, if a mouse holds its breath for more than 1 minute, it will suffer from hypoxia and suffocation, and if it takes more than 3 minutes, it will definitely die."

"Let me see, after using nano blood, how long can this mouse hold its breath?"

Xue Shen stared at the mouse in the sink through the glass and waited patiently.

The white mouse fell into the water and was very panicked at first, choking several times in succession.

Then it calmed down and floated in the water with its legs spread out, its long tail hanging down to the bottom of the tank, perhaps giving up the struggle.

"For more than 3 minutes, the mice did not appear to be asphyxiated or hypoxic."

Xue Shen suddenly became energetic and moved closer to observe carefully.

There was still nothing abnormal about the white mouse, its limbs remained motionless, only its eyes moved from time to time.

Xue Shen was very satisfied: "It's very good. I have been holding my breath for 5 minutes and there is no hypoxic reaction."

In this way, time passed slowly.

It wasn't until half an hour later that the mouse suddenly started struggling in the water.

It desperately pushed up the glass lid, its mouth opened wide, and its limbs were waving twitchingly.

The water flow was agitated, and gradually, the mouse's limbs became stiff and eventually lost its life.

"In an underwater environment, a 25g white mouse will die in 36 minutes without supplemental oxygen."

Xue Shen frowned and thought: "The survival time has been extended by about 12 times, which is quite impressive."

"The time a human can hold his breath underwater is about the same as that of a mouse. Death will occur in 5 minutes. If nano-blood is injected, the holding time should be converted into one hour."

"But the mice were too small, and the total blood volume was less than 2 ml. I directly gave 1 ml of nano-blood, which is equivalent to half of the blood."

"If it's a human, the total blood volume is 4 liters. It's impossible to transfuse too much nano-blood, and the effect will be greatly reduced."

"However, the unit density of nanoparticles can be increased. In this way, even if 300 ml is infused, it can greatly increase the oxygen-carrying capacity of the blood."

"In addition, the underwater anoxic environment is different from the normal environment. If you are on land, people will continue to breathe, and these nanoparticles will form a long-term oxygen transport cycle, giving people a strong oxygen-carrying capacity."

"So if it's not used for diving, but used for running, it will definitely be awesome."

Xue Shen couldn't help but laugh proudly when he thought of this.

"The next step is to conduct experiments on large mammals."

"Once the safety of nano-blood is verified, you can try it on yourself."

Thinking of this, his heart suddenly became excited and his breathing became a little rapid.

The next day, he excitedly found a miniature pig and prepared to conduct experiments.

This pig has a very pink nose and ears, is as big as a cat, and weighs only 5 kilograms. It is a very good drug experiment subject.

Put the piglet into a sealed box and pump the air out.

Soon, the pig had difficulty breathing due to severe lack of oxygen, and lay directly on the bottom of the box, gasping for air.

The originally pink nose turned pale, and the limbs became cold.

The little pig was about to suffocate to death.

Xue Shen quickly opened the box, inserted a thick needle into the pig's blood vessel with precision, and injected all 20 ml of nano-blood into it in one breath.

The effect was almost immediate, and the oxygen levels in the piglets that were severely hypoxic improved after receiving the injection.

The color of the skin changed from pale to pink due to lack of oxygen, and the body temperature returned to normal.

"Sure enough, it also has miraculous effects on large mammals." Xue Shen looked at this scene and was instantly overjoyed.

"It seems that nanoblood can be injected into the human body through blood transfusion, thus having extremely powerful oxygen-carrying capacity."

He clenched his fists excitedly and waved them in the air several times.

Then, his expression became serious.

“After confirming the safety of nanoblood, it’s time to proceed to the next step.”

"It's time to give yourself a shot."

However, for theoretical safety, he still waited another day.

The next day, after a blood test on the white pig, it was found that the nanoparticles injected yesterday had been decomposed and excreted, and could not be detected in the urine or blood.

Xue Shen finally felt relieved.

He prepared syringes of different sizes and planned to test them on himself in order from the smallest to the largest.

First, he gave himself a subcutaneous injection to see if it would cause allergies.

Logically speaking, nanoparticles should be very safe, but don't be afraid of 10,000, just be afraid of what happens.

All necessary precautions must be taken.

In this way, 0.1 ml of nano-blood was injected into the subcutaneous tissue of the wrist, forming a small mound, like a mosquito bag.

After a few seconds, the mosquito pack gradually disappeared.

"No abnormal reaction." Xue Shen showed a satisfied smile.

Next, he formulated rigorous and detailed experiments.

In the first week, a certain amount of nano-blood is injected before get off work every day, in order:

1l,5l,10l,20l,50l,80l,100l.

Then I went for a run and ran 5 kilometers along the river bank, which took about 30 minutes.

During this period, the smart watch will faithfully record his physical changes.
