After returning home, Meng Lang went straight down to the basement and took out the test tube containing more than a dozen fleas from his trouser pocket. 35xs

When I was with Su Xue before, I couldn't care about anything else in a hurry, and directly stuffed the test tube into my trouser pocket.

Meng Lang looked at the dozen or so small black spots in the test tube and nodded with satisfaction, but then it was a little difficult, how to get these little guys?

They are so small, much smaller than the ants last time, the tweezers can't be clamped at all, and they explode when they are clamped, and they can't play a role in research and observation!

Meng Lang thought for a while, decided to scald it with boiling water, and then went back to the house to boil a pot of boiling water, and after the water was boiled, he poured a little more into it.

He went back to the basement again, turned on the power switch of the transmitted electron microscope, and with the sound of a machine running, this big guy covering an area of more than three square meters began to operate!

Meng Lang took a pair of tweezers, carefully scooped up a flea, and placed it on the observation slide under the lens.

Soon after placing the flea under the huge lens tube, I saw that the connected computer control system automatically displayed images on three large display screens one after another.

On closer inspection, the entire appearance of the flea resembles that of a strange monster, with no wings, stubby antennae, and a sharp weapon on its mouth.

The flea has a total of six legs, especially the rearmost pair of hind legs are the most developed and stout, and Meng Lang focused all his attention on the last pair of hind legs.

The epidermis of the hind legs was gently dissected with a very fine dissecting needle equipped with a transmission electron microscope and subjected to a lens with a resolution of up to 002 nanometers.

The muscular structure inside the flea's hind legs was immediately revealed, all displayed on the huge computer screen on three sides.

Meng Lang observed carefully, and from time to time lowered his head to type a few words on the keyboard, and took a calculator next to him to calculate something.

Two hours passed, and Meng Lang pressed a few more buttons on the console of the transmission electron microscope, and suddenly the picture of the entire screen changed, and an atomic-level 3 structure diagram suddenly appeared in front of him.

It turned out that he had just activated the cold-field emission electron gun of the transmission electron microscope, which further improved the high-definition resolution of the image and the exploration rate of the electron beam energy.

The combination of these two world-class scientific methods is enough to observe the condition of the surface of the tiniest matter and to explore the structure of the substance.

Seeing this scene, Meng Lang's face flashed with a satisfied smile, and he was amazed that it was worthy of being the world's most high-end electron microscope!

Not only is the displayed image not distorted in the slightest, but it will also automatically form a 3-dimensional image, which is simply the best match for scientific researchers!

He once again carefully observed the atomic-level three-structure diagram, his mind racing rapidly, thinking and deliberating

Another hour passed, and I saw Meng Lang suddenly get up, walk out of the basement quickly, and then came to the side of the iron cage in the courtyard, and after a while, he pinched a flea.

It turned out that although the corpses of those fleas were easy to observe, they were dead objects after all, and it was impossible to know the specific changes in their bodies when they moved.

So Meng Lang grabbed one alive and came in, and first turned on the recording function of the electron microscope system.

Then he took out a very fine dissecting needle, held the flea down, and the dissecting needle in the other hand gently broke the epidermis of the flea's hind legs, and began to observe in the flea's violent struggle.

After another hour, the flea finally stopped struggling and died honorably.

He began to look at the footage he had just recorded.

The four legs in front of the flea can only be used for small trots and are at best balanced when jumping, while the two hind legs are particularly long, and the part of the body that is closest to the body is the most muscular.

However, according to Meng Lang's calculations, these leg muscles can only produce about one-tenth of the energy required for jumping.

So, where exactly does the remaining 90 percent of the force come from?

Meng Lang adjusted the resolution to the maximum, under normal circumstances, he would not lose the limit of this TEM so excessively, if he did this for a long time, the lens of this expensive TEM would be scrapped quickly!

Under the extreme resolution, Meng Lang found that the flea had a few drops of special gelatinous elastic protein inside the hind legs.

These proteins are very large but surprisingly elastic!

In a series of calculations, tensioning can store energy, tension and then release, it can return to its original state in an instant, and can release 97 of the energy in a thousandth of a second.

When the flea is ready to take off, the muscles in the flea's thighs are mainly used to tense the drop of elastin when it is squeezed to the limit.

If you suddenly relax your leg muscles, the drops of elastic protein that had been under extreme stress will suddenly recover, resulting in an extremely powerful explosive force that causes the flea to be ejected like an arrow from a string.

It's like those simple catapults in ancient times, or the steam catapults of modern NN motherships for short-range catapult fighters!

But either way, the difference is just the type of energy and the amount of energy!

This force is so huge, in Meng Lang's calculations, when the flea's body pops out, the elastic force produced by these special elastic proteins in an instant is greater than 140 times the acceleration of gravity!

So, the flea is not jumping at all, but bouncing!

It seems that the secret of these little things jumping high is here!

Meng Lang knew that he was definitely not the first person in the world to discover the secret of flea high jumping, but he was definitely the first person to have a modified cell.

Even if someone else discovers this secret, it is just a discovery, but he is completely different!

Meng Lang pondered for a moment, and he had already made a decision in his heart.

In his plan, he will copy or simulate two elastic proteins similar to the hind legs of fleas in the muscles of his two legs, so as to greatly improve his agility and make up for his biggest shortcoming!

Although changing some of the ant muscle cells in both legs to elastin would reduce the strength of the legs, it was all worth it in his opinion!

After deciding on the direction of strengthening his legs, Meng Lang did not stop there, and started to think again.

Instantly reaching 140 times the acceleration of gravity, this staggering intensity is enough to crush a person into a puddle of flesh in an instant.

The fleas are not only safe and sound, but they can also jump every four seconds for three days and three nights.

What is the mystery hidden inside? 11
