Chapter 872 I Am The Wind (Fourth Update)
The two students of C208, who were named, turned their heads away from the window a little disappointed.

Then Wang Hongchun looked at Yan Xuexin blankly: "What did he say just now? Need to speed up? It's so fast now!"

Yan Xuexin took out his mobile phone, glanced at it, and said, "Our current speed is about 35 kilometers, which is double the wind speed. Of course, we can still accelerate."

Wang Hongchun: "?????"

Can it be accelerated?
At this moment, Wang Hongchun really felt that he was uneducated.

"Sailboat, can it accelerate faster than the speed of the wind?"

"Who said we are faster than the wind?" Yan Xue said.

"Didn't you just say that the wind speed has doubled..."

"I'm talking about the wind speed outside of us, the wind speed at sea, and the wind speed relative to the ground. This is called true wind. Our own wind speed, look..." Yan Xuexin pointed to the anemometer outside the window.

The anemometer was spinning fast.

"Don't forget, we're driving against the wind, so there's another wind, called the marching wind, that comes from our motion relative to the air. And the wind we feel is called the 'apparent wind,' and our apparent wind speed is The wind speed of the true wind at the current angle, plus the speed of the ship itself... That is to say, the current apparent wind speed is about 50 kilometers..."

"That is, we can accelerate to 50 kilometers per hour?"

"No, when we accelerate to 50 kilometers per hour, our apparent wind will be close to 70 kilometers, the thrust on the sail will continue to increase, and the speed of the ship will continue to increase..."

"Then we can accelerate to 70 kilometers?"

"No, the apparent wind will be about 85 kilometers by then..."

Wang Hongchun: ...

???

"In other words, we ourselves are the wind. The faster we go, the stronger the wind, and we can continue to accelerate!" Yan Xuexin explained.

Wang Hongchun understood, but he felt that he didn't understand at all.

We are the wind?
We blow ourselves up?
I can even step on the left foot and step on the right foot, so I can use the ladder to fly all the way to the sky!
You must be lying to me!
But looking at Yan Xuexin's expression and thinking about the other party's IQ, Wang Hongchun felt that it must be no pleasure to lie to himself with Yan Xuexin's IQ.

He doubted: "Then... the sailboat can accelerate infinitely?"

The speed of the apparent wind increases, then the thrust of the sail increases, then the speed of the boat increases, then the apparent wind increases again, then the thrust of the sail increases again, and then...

Isn't this endless!

At this moment, Wang Hongchun just wanted to yell: No nesting dolls!

This unscientific!

But the facts proved that Yan Xuexin was right.

At this moment, all the ships following the "Sea Dragon Palace", counting as one, have been thrown off.

In this world, the economic speed of most ships is only 15-20 knots, that is, thirty to forty kilometers. Now the speed of the "Sea Dragon Palace" is almost fifty kilometers per hour. Everyone on those ships stared dumbfounded. Looking at the "Sea Dragon Palace", it is like a leaked balloon, whizzing and rushing forward.

They just want to yell, "Wait for me!"

Whether it's them, the netizens and audience watching the live broadcast, their eyes are about to pop out.

This is unscientific, really unscientific!
Sailing, against the wind, how could it be so fast!
And, it's still accelerating!
"In theory, it is possible to accelerate infinitely." Yan Xuexin explained to Wang Hongchun: "Don't forget, as long as the wind is blowing, it is continuously inputting energy into this system. The bigger it is, the closer the ship is to the state of facing the wind, and the lateral thrust will become greater and greater. Before we accelerated to a particularly fast speed, we were already overturned by the crosswind... In addition, there is also the sea water. The problem of drag, the smaller the angle between us and the front wind, the smaller the forward thrust, and after the thrust and drag are balanced, we can no longer accelerate..."

Sure enough, before Yan Xuexin's words fell, Wang Hongchun suddenly felt that the whole ship began to tilt slowly.

The water in the cabin is no longer able to suppress the terrifying lateral thrust brought by the current speed.

Such a colossal "Sea Dragon Palace" feels like it is going to be overturned.

Now, it was Yan Xuexin's turn to change his face: "No, it's not scientific!"

With a monster as huge as the "Sea Dragon Palace", before it accelerates to the limit, the "wave petal" itself may not be able to withstand such a huge pressure, and it will bend or break.

But he did not expect that the "Sea Dragon Palace" is special.

On the one hand, it is because the "Sea Dragon Palace" is made of a large amount of foaming materials, so the weight itself is actually very light, and the force required to overturn it is not particularly large.

At the same time, its real body is actually the "floating empire" sea stage rewarded by the system, so its strength is ridiculously high, close to "indestructible".

That's why those "wave petals" can withstand such a strong pressure without deforming and destroying.

In the rear, those ships that were still desperately chasing behind the Sea Dragon Palace were going crazy.

They saw that the "Sea Dragon Palace" in the distance was like a child skating on one leg, using one foot to slide forward on the sea surface, and the inclination became more and more serious...

On the bridge, Wang Guanshan also yelled: "Ahhhhhhhhh, we're going to flip over! We're going to flip over!"

Gu Xiaobai's voice sounded again: "Sea Dragon Palace is about to start the three-stage acceleration, the two students of C208, don't be shy, please fasten your seat belts!"

What?There are three stages of acceleration?
This time, even Pi Ruyan Xuexin and Wang Hongchun didn't dare to make trouble.

The two of them returned to the sofa next to them and fastened their seat belts obediently.

Gu Xiaobai entered a few commands again, and under his control, the two "wave petals" on the left side of the "Sea Dragon Palace" rotated and flattened...

The terrifying strong wind blew past the two "wave petals" that reversed direction, forming a strong downward pressure, like the "tail" of a car, pushing down the left side of the "Sea Dragon Palace", and re- Pressed back to the surface.

The "Sea Dragon Palace", which was tilted up and about to overturn, began to be flattened slowly and returned to the sea water.

And the other "wave petals" are also adjusting their direction. In addition to the lateral and frontal pressure, an upward force is generated, and the seawater in the ballast is discharged, starting to reduce the weight of the entire "Sea Dragon Palace".

Sea Dragon Palace, start the whole ascent.

"An illusion? I feel like I'm in an elevator..."

"Looks like we're going up... damn it... isn't it!"

Three stages of acceleration, complete!

Speed, 50 knots!
92.6 km!

Nearly three times the speed of the wind!

In the rear, under the witness of countless people, they saw that the lower part of the Sea Dragon Palace gradually left the sea, leaving only a few plate-shaped keels, like hydrofoils, still soaked in the sea, splitting the sea, against the strong wind, The way forward.

At this moment, countless people felt Wang Hongchun's words.

It is said that even pigs can fly in the air.

It is said that when the wind stops, all that fall are pigs.

But at this moment, I am the wind!
