See you soon Douluo

Chapter 89 Water Rocket

It is said that Chengying has always been obsessed with catching and shaving a hundred thousand year old soul beast. After all, the space elevator seems to have no technical threshold, but if he really wants to do it, the difficulty of materials science is simply mind-numbing.

But with the current strength, it is definitely impossible to achieve this. If you want to reach the sky, it is more reliable to rely on rockets, and the difficulty of rockets in other worlds is surprisingly low.

Just look at the Apollo spacecraft when it landed on the moon. It had three levels of acceleration. Every time it accelerated, a bunch of boosters were thrown away. Why? That's of course because the booster sinks! If you run out of fuel, you will become a burden!

But there is a storage soul guide in another world! Even if the soul power will be lost in the high altitude, it does not mean that it will drain out. The soul power that opens the soul guide can still be used.

When the time comes to install 1,800 tons of fuel, the difficulty of getting into space will plummet. Especially with the storage soul guide, the construction of the space base will be much easier.

Because the storage soul guide can have unlimited matryoshka dolls! To explain simply, the meaning of the infinite matryoshka doll is that you can put a bunch of storage soul guides into another one, and then put a bunch of storage soul guides filled with storage soul guides into another one. Inside a new storage soul guide.

Theoretically, infinite nesting dolls mean unlimited space. As long as you can accumulate resources ruthlessly, it is really not a joke to build a spaceport with a self-circulating ecosystem at once.

Every time he thought about this, Cheng Ying couldn't help but feel excited, because as long as a spaceport is built in synchronous orbit as a counterweight in outer space, there is really only one rope left to build a space elevator.

But as his feet landed again, he also put back his thoughts of letting go. Looking at the twisted airplane assembled by his disciples, he couldn't help but twitch the corner of his mouth. The design was probably a little more complicated.

The most reliable person to assemble is Dugu Bo, who is as good as a top student, but I have to say that in terms of progress, Bo Saixi is the fastest. The adventurous girl's desire for heaven is unparalleled.

Even from the outside, she had completed assembling the aircraft, but looking at the pile of extra parts on the ground, one had to wonder whether this thing could fly.

"Forget it, let me give you some guidance!" If they continue like this, they will never be able to complete their plane before the sun sets. In this era, flying at night is asking for death.

……

Half an hour later, there were only three planes out of a total of five, because two of them were completely damaged and repairing them was more troublesome than building a new one.

But at least it gave the disciples a chance to go to heaven before dark. Chengying and Bingdi sat in the passenger seats to prevent any driving accidents.

After all, the two of them can fly, so even if the plane explodes in mid-air, there won't be any problem.

The first ones to go to the sky were Bo Saixi and Dugu Bo. They could only go up to two at a time. After all, as the Ice Emperor had learned from their mistakes, there was a high possibility of them falling from the sky.

Cheng Ying was responsible for taking care of Bo Saixi. Under his guidance, the plane soon began to accelerate. Bo Saixi was unexpectedly talented in driving.

"Teacher, is this what you mean by rolling in the air?"

The plane made a 360-degree loop in mid-air, spinning around like a drill. Chengying lay dizzy on the back seat. If he hadn't eaten this morning, he would definitely have eaten everything in his stomach. Spit it out. "Can you please not do the operation first and then ask me about the teacher? You are going to vomit the bile of a teacher like this." The experience of flying and flying are completely different, just like someone driving a car without getting dizzy no matter how hard it is. When I got to the passenger seat, I immediately felt like I was going to die.

"Oh! Got it, teacher, can this and the joystick be used for super acceleration?" Bo Saixi awkwardly pointed to a joystick painted red on his left hand side.

"That's right, this is super acceleration, but it's not necessary~ahhhhhh~" Before Cheng Ying could finish saying "Don't use it as a last resort, don't use it," Bo Saixi had already pushed the joystick.

Immediately, an unparalleled push on the back pressed the two of them on the driver's seat, unable to move. There was at least 10G of acceleration. If the two of them were not good at cultivation, they would probably vomit blood from the pressure.

Viewed from the ground, the tail of the plane suddenly extinguished the flames. Some people may wonder, if the flames are extinguished, why is it super-accelerating instead?
  This is about water rockets. Although not everyone has played with this thing, they have more or less heard of it. It relies on the air pressure in the rocket to spray out the water in the water rocket to achieve propulsion. principle.

To put it bluntly, water rockets are more powerful than pure injection of high-pressure gas. It is a matter of conservation of momentum. To put it simply, if you want to push yourself, there must be something to withstand the reaction force.

Under normal circumstances, airplanes naturally use gas to provide reaction force, but the density of gas is so low! A lot of gas needs to be ejected to provide a little reaction force, so Chengying got very creative and used the storage soul guide to inject water into the combustion chamber. A large amount of water was injected into the two combustion chambers one after another, and the high-pressure gas sprayed out the water to provide A huge amount of reaction force...

The visual effect is that with a swish, the plane shoots out like a flying monkey. This move is mainly to prevent the soul master from chasing after him. After all, facing a soul master who can fly, the plane will not have much advantage. It is possible that the Soul Saint or even the Soul Douluo will go around to the blind spot behind and chase them.

At this time, a normal aircraft would definitely be in trouble, but imagine that super acceleration is activated and the aircraft accelerates to escape pursuit. At the same time, the pursuing soul master is suddenly covered in a high-temperature and high-pressure white turbid liquid. What on earth is this? The experience is exciting just thinking about it!

It's just that Bo Saixi obviously used this trick in the wrong place... Bo Saixi, who was pinned down on the seat, couldn't even lift his hand to push the joystick back.

A total of twenty tons of water was sprayed cleanly by her. Under this acceleration, Cheng Ying only had time to release a layer of eggshell-like soul power to wrap the two people in the cabin. The next moment, the plane crashed out. The sonic boom cloud...

The first test flight of a supersonic aircraft in human history was completed in such an informal atmosphere.

Everyone in Yuehui City saw the supersonic fighter plane dragging a white line roaring in the sky. No one thought that it was a human being. After all, no one could fly that fast. Titled Douluo could not supersonic speed unless needed in battle.

Everyone regarded this as a good omen from the sky, because the trajectory left by the steam in the sky was as straight as a sword, just like the leaves of Clivia. Some even claimed that this was a revelation from the gods, and that it was a revelation to them that trading Clivia was favored by the gods. …
