The arteriovenous blood vessels in the human body, large and small, long and short, and the total length can be more than two circles around the earth, criss-cross the body, intermingling with each other, seemingly messy but orderly.

White blood cells are like loyal guards, patrolling all parts of the body. In any war against viruses, bacteria, and parasites in the body, these little guys who are only 10 microns are the first echelon to resist the front!

Immunoglobulin antibodies act as sentinels, they flood the bloodstream in large quantities, and when they detect the virus, they immediately raise a beacon fire to alert the entire immune system to an enemy invasion!

Moreover, these globulin antibodies are a group of grudge-holding stingy guys, and all bacteria that have invaded the human body will be remembered by them and the memories will be stored.

The next time a similar virus enters the human body, the immune system will immediately recognize it and send troops according to the intensity level!

Red blood cells are responsible for the logistics, they work tirelessly carrying oxygen around the body all day long, sending oxygen to where it is needed, and on the way back, they have to take carbon dioxide with them, and then send them back to the capillaries of the lungs for Meng Lang to exhale out of the body!

The phagocytes are like the vanguard of the charge, catching a few flu viruses and biting wildly. If the virus is too powerful and the phagocytes are unfortunately killed, then its big brother macrophages will blatantly go out to avenge their little brother!

In addition, there are several elite T lymphocytes in the body that are ready to go.

They are like special elite troops in the army, they usually do not go out, lurking all over the body, and once the virus that invades the body is too strong for other immune cells to resist, they will swarm and kill the virus that invades the body to the slag!

All kinds of immune cells formed a multi-arm mixed field army in Meng Lang's body, organizing a solid defensive barrier in his body to resist the invasion of various viruses and bacteria from the outside world!

In the end, Meng Lang even went to the tadpole production workshop to observe for a while.

This is two symmetrical oval production workshops, the production efficiency is efficient and stable, under the full operation, is constantly producing these fresh and lovely tadpoles at a rate of 300~600 per second.

Watching the energetic tadpoles being produced from the production line and then transported to the storage tank for storage, his heart was suddenly filled with an indescribable sense of pride and satisfaction that only a man can understand!

According to statistics, a man can produce a total of about 80 liters, that is, about 160 catties of tadpoles in his lifetime. Thinking about this incredible data, he couldn't help but marvel at the greatness and wonder of the Creator!

At this time, a feeling of exhaustion came from all over his body, and Meng Lang had to retreat from the state of inner vision.

He knew that this was due to the fact that the first internal vision consumed a lot of energy in his body, and his mood was too ups and downs, so it was actually no longer suitable for him to continue cultivating today.

After driving the car out of the quarantine area, he parked the car on the side of the road, then took out a shovel that he had prepared when renting a car from the car, dug a hole in the grass on the side of the road, and buried all the things used in the quarantine area, such as protective clothing.

It would be a sin to throw away these things that have been contaminated with radiation rays, in case they are picked up by someone who doesn't know!

As for the off-road vehicle, he wanted to leave it in the quarantine area, but considering the quarantine area, it is still more than 120 kilometers from the city. In addition, there is not even a ghost in the wilderness here, so it is impossible to take a ride!

I had to continue to drive back to the hotel, and then spend some money to buy it and send it to the scrapped car factory, when these scrapped vehicles are flattened by heavy machinery, and then returned to the furnace to make iron, the whole process is basically not in contact with the human body, avoiding the possibility of someone being secondary radiation!

Meng Lang then ran around, it was already night, and at dinner, he ate a large steak for two people in the surprised eyes of the waiter in the restaurant, and drank three glasses of milk and a large glass of juice.

Meng Lang patted his slightly swollen belly, and sighed in his heart that although this method of obtaining energy could satisfy the desire of the tongue, it was too low-level.

In the future, when you become stronger and stronger, you will definitely not be able to meet the huge energy demand in your body just by eating, and it seems that the transformation and evolution of this aspect will also have to be put on the agenda. Of course, that's all for later!

At the checkout, he gave an extra $10 as a tip for the waiter, and the waiter, who had beautiful blonde hair, walked out of the restaurant in a dashing manner with the surprised eyes of the waiter.

Back in his hotel room, he lay on the bed with his hands behind his head and pondered his next evolutionary direction.

At present, there is not much time left for his visa to stay in Ukraine, and it will expire in about a few days. If the inner vision evolution is not successful, he will have to go home.

When he came here, he didn't expect that this evolution would be so smooth, after all, even Qingchengzi had spent a whole year cultivating the power of inner vision.

In addition to the fact that there is not much time to stay in Ukran, some knowledge reserves related to the human body and other preparations are also insufficient!

The experience of inward vision during the day made him sigh at the complexity and sophistication of the human body, and the red and white blood cells and phagocytes he saw in the morning were only the tip of the iceberg of the immune system!

In addition to the immune system, there are nine major systems in the human body, such as the digestive system, nervous system, and endocrine system, which work in harmony with each other in the body.

If the human body is compared to a machine, it is undoubtedly the most complex and sophisticated machine on earth!

In the face of such a masterpiece, it is understandable that some people in the world suspect that the origin of human beings did not evolve naturally!

And this kind of proposition is too huge, and naturally it is not something that Meng Lang can explore now.

The most intuitive feeling of this evolutionary experience is that he urgently needs an army of cells that truly belongs to him!

Although the cells in his body do belong to him in some ways, it can even be said that these cells are himself, and he is both prosperous and lost!

But among the trillions of cells, none of them obeyed him and were commanded by him! As if they were born with some kind of command, they operate on their own for the rest of their lives, and they are not at all able to command them as their master.

What's more, there are countless possibilities for genetic mutations and mutations, and it is impossible for Meng Lang to hand over every evolution in the future to fate for random selection.

The success of this evolution of the power of inner vision can be said to have a great element of luck in it, and he can't guarantee that there will be such luck next time.
