Chapter 147 The Sound Barrier
According to the encyclopedia, the fastest flying creature on the earth is a bird called the sharp-tailed swift, and its fastest speed can reach 100m/s.

What is this concept?
It is equivalent to the [-]-meter race, the second hand has just moved, and it has already flown to the finish line, which is unbelievably fast!

And Si Zhai's current speed is three times faster!
Different from other creatures, other creatures can't increase this speed. The body structure is one reason. The biggest reason is the physical endurance. If their physical flying ability reaches this speed, they will probably fall apart because they can't bear it. .

But Sizhai, who is a parasitic beast, doesn't need to worry about this. The powerful cell manipulation ability of the parasitic beast allows him to quickly discover tissues that are close to collapse, so as to further improve that part of the tissue and gradually increase the endurance of the physical body. Perfect.

But at 300m/s, it is already a hurdle. Si Zhai feels that the increase in speed is getting slower and slower. At this time, what affects the speed is not the body's ability to withstand it, but more detailed aspects, such as the shape and structure of the body, the relationship between the body and the air. Friction area and so on.

In order to further increase the speed, Si Zhai tried to change the shape of the body, the whole body began to change towards a streamlined shape, gradually reducing the area of ​​friction with the air, and gradually increasing the smoothness of the body surface, so that the friction force was further reduced.

When Si Zhai focused on modifying his body shape, he didn't realize that his speed was getting closer and closer to the speed of sound...

310m/s...320m/s...330m/s...340m/s...

Si Zhai suddenly found a conical cloud barrier in front of him. Before he could react, his whole body plunged into the barrier.

The cloud and mist barrier was like a wall made of mercury, Si Zhai felt strong resistance as soon as he plunged in, and the pair of huge bat wings were blown off by the huge force as soon as he entered.

Relying on inertia, Si Zhai rushed out of the cloud and mist area, and his body without bat wings fell quickly.

Si Zhai, who was falling, was repairing his bat wings while frowning at the conical cloud barrier above. Obviously, he still hadn't figured out what was going on.

Just as Si Zhai was thinking, an explosion-like roar came from the barrier above.

Si Zhai was stunned for a moment, and understood what was going on.

This is the sound barrier, a kind of sound wave barrier that is only produced when the speed of an object approaches or exceeds the speed of sound.

As we all know, sound propagates in the form of waves. When a moving sound source approaches or exceeds the speed of sound, the sound waves emitted after it will catch up with the sound waves emitted before, and the air between the two sound waves is compressed, which becomes The conical cloud that Si Zhai saw just now.

And this conical cloud is the external manifestation of the sound barrier.

In other words, just now his speed was close to or even surpassed the speed of sound!
When he was about 500 meters away from the ground, Si Zhai repaired the bat wings on his back, adjusted his body balance, and flew to the top of a building with bat wings flashing.

In terms of flying speed, Si Zhai doesn't plan to improve it any more.

The sound barrier is too destructive to the body, even if Si Zhai has time to repair it, it will greatly slow down his speed.

He decided to set the limit speed of the flight at around 330m/s in the future, which will not cause a sound barrier, and the flight speed is also very fast.

Next, Si Zhai decided to continue what he hadn't done during the day - strengthening the insulating cells!
Regarding Si Zhai's random transformation of the body, Sanshengmu wanted to complain, but Si Zhai could control every part of the body, directly controlling her tongue, so she couldn't say anything, she could only watch.

Since during the day when San Shengmu was eating, Si Zhai had already transformed many discharge cells, and each cell was fully charged with energy. What he has to do now is to see if he can insulate the body before the energy is exhausted. To what extent is sexuality elevated.

Then during the daytime experiment, Si Zhai used blue-purple electric current as soon as he came up, and a body that merged with the darkness appeared, and a human form wrapped in blue-purple electric current appeared.

With the previous strengthening experience, Si Zhai also let go a lot. He did not suspend the current output, but directly increased the discharge capacity on the basis of the previous one.

Immediately, the electric current around the body doubled, and the thunder figure in the darkness also swelled up.

In the blue-purple current, the purple became deeper.

Si Zhai increased the output intensity of the current bit by bit, and when the body couldn't bear it, he quickly strengthened the insulating cells.

When the current around his body completely turned purple, Si Zhai stopped the output. He found that although the insulating cells could still hold on, the discharge cells couldn't.His current discharge cells are like a super generator with 2mm wires. The power generation is huge, but the output can only output a little.

Just now, because Si Zhai increased the output to exceed the load capacity of the 'wire', the 'wire' (cell) was blown all of a sudden.

For such a result, Si Zhai had a bit of a headache. He didn't expect that the insulating cells hadn't reached their limit, but the discharge cells had reached their limit first. This is really not good news.

Because it is simple to make cells insulated, you only need to remove some conductive substances, but Si Zhai can't do it to increase the conductivity of cells, because it needs to add some stronger conductive substances in the cells , He can't do something like this out of nothing.

The matter of optimizing cells can only come to an end, Si Zhai looked around.

I saw that on the land where he was, within a radius of 100 meters, there was no longer a single plant, the ground was covered with black ash, many charred branches were still smoking, and there were traces of blue current on the ground. Flashed by, there was a slight hiss.

Si Zhai shook his hand at a big tree in the distance, and suddenly a burst of purple and blue current shot out, hitting the thick trunk, leaving a large scorched black mark.

Si Zhai looked at the hand and shook it.

The intensity of the current is still not enough, and it is not comparable to the real lightning. The real lightning can split a big tree in half with just one blow.

But the body's discharge cells have reached the limit, and there is no object for comparison, what standard should one's own insulation cells use to strengthen?

He can't really go to be struck by lightning, so he probably killed himself before meeting Thor...

Si Zhai was pacing up and down in the open space, and suddenly thought of the solution he had thought of to deal with the next superhero, and a solution popped up.

Si Zhai lifted the 'speaking ban' on San ShengMu, restored her personal freedom, and turned himself into a little flesh man.

Just as San Shengmu was about to scold Si Zhai to relieve her anger, she found that Si Zhai reached out and smiled innocently: "Honey, I need your help with something..."
