Meng Lang then began to observe the internal structure of the flea's body with great interest.

Its body is particularly flat, so it is particularly resistant to pressure, and it is difficult to strangle it with your fingers.

Meng Lang knew that this was an exoskeleton structure composed of chitin.

Many insects, such as ants and insects, have this structure, while humans belong to the endoskeleton category.

Generally speaking, it is the difference between meat and bone and meat, and these two structures have their own advantages and disadvantages.

However, despite the fact that the flea has such a special skeletal structure, these alone cannot guarantee that its internal organs will not be shattered!

Meng Lang pondered for a moment, and then adjusted the angle of the transmission electron microscope lens, and the computer screen suddenly showed a high-definition three-dimensional image of the inside of the flea.

Its body is filled with fluid, a nutrient solution containing amino acids, proteins, fats, and inorganic salts, in which the flea's organs are immersed.

These fluids not only provide nutrients for its internal organs, but also act as a great buffer against vibrations and impacts.

Wrapped in an exoskeleton, the flea is actually a beating droplet!

So even if the flea jumps or hits something, its internal organs will not be damaged!

In fact, this nutrient solution is the blood of fleas, which feed on blood to replenish the fluids in their bodies.

If you look at the flea in an N-shape, then it is a vampire who likes to hide in dark corners and has a very high agility!

It has most of the qualities of a vampire!

Meng Lang observed this, and couldn't help but sigh, if he wanted, he could completely transform himself into a vampire who lived by sucking blood.

And a vampire who is not afraid of crosses, holy water, and garlic at all!

However, this kind of non-human body structure is not blessed to enjoy, even if theoretically the modified cells can carry out all aspects of physical transformation in this direction, not only their own psychology will not be able to pass the non-human level in the first place.

And the most important thing is that even if he succeeds in transformation, he is just an enlarged version of a flea, except for jumping high and far, and sucking blood to make a living, it is not of much use!

Despite this, there are some special structures inside the flea body that can be applied to themselves.

Images on the computer screen showed the flea with many tracheas scattered throughout its body.

Therefore, all parts of its body can get enough oxygen supplement, which is estimated to be the fundamental reason why it can jump for three days and three nights in a row!

Needless to say, the importance of oxygen is that all cells in the human body need to breathe, which may be a direction that can be studied

After a long time, Meng Lang woke up from his contemplation, he shook his head, put these distractions behind him, and began to focus on the leg transformation in front of him.

After a while, Meng Lang got up again and walked out of the basement.

When he returned to the house, after a while, he came to the side of the iron cage again with a vacuum cleaner in one hand and a pair of scissors in the other.

Next, in the frightened eyes of the three dogs, Meng Lang turned into Tony in the barber shop at the head of the village.

He turned on the vacuum cleaner and waved the scissors in his hand to cut all the dog hair off their bodies.

In the end, the vacuum cleaner really couldn't hold so much dog hair, and the remaining white dog survived and escaped the clutches of "Tony"!

Meng Lang looked at his masterpiece with satisfaction, and shook his head self-deprecatingly, secretly sighing that the idea of catching fleas with his hands in front of him was too much, and he didn't catch much.

After clapping my hands, I took off the storage bag under the vacuum cleaner, which was not only full of dog hair, but also a lot of fleas!

He then soaked the bag containing the fleas into a pot of boiling water.

After waiting for a while, it is estimated that all the small things inside are cold, and then I opened the storage bag and picked out all the small black spots one by one.

It was a painstaking and meticulous job, and after a while, Meng Lang finally got a small ball of fleas.

Then he went back to the basement and took out the separation centrifugal machine that he hadn't used for a long time, intending to separate the flea muscles.

But after a while, Meng Lang was stunned.

It turns out that the size of these fleas is so small that even centrifuges can hardly isolate the fine elastin in the hind legs of the fleas.

Do you have to pick it out slowly and little by hand?

As soon as he thought of this, Meng Lang was a little desperate!

He thought about it for a moment, and felt that he was simply not up to the task.

However, under the strengthening of his body, he still stubbornly put these fleas back under the lens of the transmission electron microscope.

Facing the enlarged image on the computer screen, he began to slowly use the dissecting needle to pick out the elastin in the hind leg of the flea one by one.

At the same time, in order to prevent spoilage caused by too much time, he also took a few ice cubes from the refrigerator and put these selected elastane proteins on the ice cubes for preservation.

In this way, the action of selecting the egg whites was repeated mechanically, after about one-third of the fleas were selected.

Meng Lang estimated that it was almost enough for a test, so he found a disposable syringe and glucose injection in the cabinet next to him.

These things have basically become his daily necessities, so there are a lot of them.

After mixing the flea elastin and glucose liquid, he injected it into his arm without hesitation.

At the same time, the injection also instantly entered the state of internal vision, mobilizing more than 500 million modified cells to gather at the place where the needle was inserted.

Since the muscles have been remodeled in the main blood vessels of the muscles, there is no contact with immune cells here, and in the muscles, it is the territory of the modified cells!

Soon, a vigorous devouring feast unfolded, compared to the modified cells, these elastins are still too huge, only to see hundreds of modified cells surrounding a grain of elastin, began to devour wildly!

Meng Lang estimated the time, and felt that the speed of phagocytosis of modified cells was still too slow, so he took out albumin injection solution and fat emulsion nutrient solution.

After mixing, there is no need to sling the needle, and the full cylinder is directly drawn with a disposable syringe and injected into the arm.

With the entry of these milky white liquids, the speed of cell modification has increased significantly!

In this way, once the speed of the cells slows down, he is injected with a mixed nutrient solution to maintain the high-speed phagocytosis of the modified cells.

After an hour, a full 1,500 ml of mixed nutrient solution was injected, and the phagocytosis of the modified cells was in the end.

After a little more waiting, the last grain of elastin was finally swallowed up by the engineered cells!

Meng Lang carefully observed these engulfed cells, except for eating roundly, there was no change, although he was a little disappointed, but all this was expected!

He estimated that it would be a long process of mutation, and if he was lucky, he might succeed in mutating in the next second, and if he was unlucky, it wouldn't be a hundred years!
