The two classmates of C208, who were named, took their heads back from the window in a little disappointment.

Then Wang Hongchun looked at Yan Xuexin with a blank expression: "What did he say just 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, and of course we can accelerate." ”

Wang Hongchun: "?????"

Can it still be accelerated?

At this moment, Wang Hongchun really felt that he was uneducated.

"Can a sailboat accelerate faster than the wind?"

"Who said we're faster than the wind now?" Yan Xuexin 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, the wind speed relative to the ground, and this is called the true wind. Our own wind speed, you see ......" Yan Xuexin pointed to the anemometer outside the window.

The anemometer is already spinning fast.

"Don't forget, we're driving against the wind right now, so there's another kind of wind, called the marching wind, which comes from the movement of our relative air. The wind we feel is called the 'apparent wind', and our apparent wind speed is the speed of the real wind at the current angle, plus the speed of the ship itself...... In other words, the current apparent wind speed is about 50 km......"

"That is, we can accelerate to 50 km/h?"

"No, when we accelerate to 50 km/h, our apparent wind will be close to 70 km/h, and the thrust on the sails will continue to increase, and the speed of the boat will continue to increase......"

"Then we can accelerate to 70 km/h?"

"No, it will be almost 85 kilometers by then......"

Wang Hongchun: ......

？？？

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

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

Are we the wind?

Do we blow ourselves ourselves?

I can also step on my left foot and my right foot, use the cloud ladder, and 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 deceive himself with Yan Xuexin's IQ.

He will be suspicious: "That...... Wouldn't the sailboat be able to accelerate indefinitely?"

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

Isn't that endless!

At this moment, Wang Hongchun just wanted to shout: ban nesting dolls!

It's not scientific!

But it turns out that Yan Xuexin is right.

At this moment, all the ships that followed the "Dragon Palace on the Sea", one of them was counted as one, and they had all been left behind.

In this world, most of the ships, the economic speed, is only 15-20 knots, that is, thirty or forty kilometers, now the speed of the "Sea Dragon Palace" is almost fifty kilometers per hour, and all the people on those ships are stunned to look at the "Sea Dragon Palace", like a leaky balloon, swishing, rushing forward.

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

Whether it is them, the netizens and viewers who watched the live broadcast, their eyes are about to pop out.

This is not scientific, it is really unscientific!

Sailing, headwind, how can it be so fast!

And, it's still accelerating!

"Theoretically, it can be accelerated indefinitely, yes. Yan Xuexin explained to Wang Hongchun: "Don't forget, as long as the wind is blowing, it is constantly inputting energy into this system, of course, it can make it continue to accelerate, but in order to get enough thrust, the greater the speed, the closer the ship is to the state of positive headwind, and the lateral thrust will become larger and larger...... In addition, there is the problem of the resistance of the seawater, the smaller the angle between us and the positive headwind, the smaller the forward thrust, and after the thrust and drag are balanced, it can no longer accelerate......"

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

The water pressed in the cabin could no longer suppress the terrifying lateral thrust brought by the current speed.

Such a behemoth "Dragon Palace on the Sea" feels like it is about to capsize.

At this moment, it was Yan Xuexin's turn to change his complexion: "No, this is not scientific!"

With such a behemoth as the "Sea Dragon Palace", before it accelerates to the limit, I am afraid that the "wave valve" itself will not be able to withstand such a huge pressure, and will bend or break.

But he didn't expect that the "Dragon Palace on the Sea" was a special place.

On the one hand, because the "Sea Dragon Palace" is made of a large amount of foam material, its weight 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" maritime stage rewarded by the system, so its strength is ridiculously high, close to "indestructible".

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

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

They saw that the "Sea Dragon Palace" in the distance was like a one-legged skating child, sliding forward on the sea with one foot, and the inclination became more and more powerful......

In the bridge, Wang Guanshan also shouted: "Ahh

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

And what? And three stages of acceleration?

This time, even Pi Ruyan Xuexin and Wang Hongchun didn't dare to wave.

The two of them went back to the couch next to them and obediently fastened their seat belts.

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 stretched out......

The terrifying strong wind blew through the two "wave petals" in the flipped direction, forming a strong downward force, like the "tail wing" of a car, pressing down the left side of the "Sea Dragon Palace" and pressing it back to the surface of the sea.

The "Dragon Palace on the Sea", which was originally warped and was about to capsize, began to be slowly flattened again and returned to the sea.

The other "wave petals" are also adjusting their direction, and in addition to the pressure on the side and forward, an upward force is generated, and the seawater in the ballast is discharged, and the weight of the entire "Sea Dragon Palace" is reduced.

Sea Dragon Palace, begin the entire ascent.

"Delusional? I feel like I'm in an elevator......"

"It's like we're on the rise...... Groove ...... Isn't it?"

Three-stage acceleration, done!

Speed, 50 knots!

92.6 km!

Nearly three times the speed of the wind!

Behind, under the witness of countless people, I saw that the bottom of the Dragon Palace on the sea gradually left the sea water, leaving only a few plate-shaped keels, like water wings, still soaked in the sea water, splitting the sea water, against the strong wind, all the way forward.

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

It is said that on the tuyere, even pigs can fly.

It is said that the wind has stopped, and all that falls are pigs.

But at this moment, I am the wind!
