On the Dragon Palace on the sea, Jiang Wei was lying in the bedroom, sleeping deeply.

His eyebrows twitched from time to time, and beneath his eyelids, his eyeballs were rolling.

Apparently, he is now in the "rapid eye movement" phase, which is known as "dreaming".

In the dream, he was spending candles in the cave room, Wei Qing's Wei Wei named Chen Song, and a little daughter was waiting for the boudoir, after hearing that Jiang Wei was not yet married, he entrusted Wei Qing to be a matchmaker, and at Wei Qing's request, Jiang Wei and the woman met.

At the time of Emperor Wu of the Western Han Dynasty, the atmosphere of marriage was still relatively free.

When the two of them met, Jiang Wei actually felt good.

After getting along for a while, Jiang Wei was conquered by this gentle woman.

And then, everything was incredibly fast.

All of a sudden, the cave room was full of candles.

I like to be a father all of a sudden.

suddenly became the father of the two babies.

Wait, this car is too fast!

Jiang Wei felt like he was on a rampaging train, so fast that he couldn't brake, and the doors were already welded shut, so he didn't have time to think about it.

Sometimes, Jiang Wei felt like he was watching everything happen, he couldn't control the direction of the story, like a bystander.

But this is my life!

What the hell is wrong with me!

Jiang Wei woke up by chance, but was soon dragged into the dream again, unable to extricate himself.

Time keeps ticking.

Following Wei Qing and Huo Quai's several expeditions, Jiang Wei has already made great contributions and was made a marquis.

In the northwest, the Xiongnu were defeated and basically pacified, and they were no longer able to disturb the border passes.

But in the southeast, the South Vietnamese state was in turmoil.

On this day, Emperor Wu of the Han Dynasty gathered his army and sent troops to the southeast to conquer the country of Nanyue!

Because of his outstanding military achievements, Conghou Jiangwei was appointed as the general of Fubo and went south to attack the South Yue Kingdom.

Jiang Wei said goodbye to his wife and two children and went all the way south!

......

in another room.

Gu Xiaobai lay on the bed and slept for a long time.

Then he opened his eyes suddenly.

Odd......

He was obviously planning to complete the task, why wasn't he pulled into the task by the system?

He took out his mobile phone and saw that it read: "The Maritime Silk Road mission is underway." ”

Ongoing?

Are you stupid about the system?

I'm still here, what are you doing?

Gu Xiaobai lay on the bed, not knowing for a while whether he should continue to sleep.

It doesn't seem to be much use to sleep again......

"This useless system is always unreliable when it is needed......"

Obviously, he now needs the ability to "manipulate the currents" that the "Maritime Silk Road" mission rewards.

This system always drops the chain at a critical moment.

Sure enough, you can't rely on this guy, you have to figure it out yourself!

At this moment, Gu Xiaobai heard someone knocking on his door.

Wang Guanshan's anxious voice came from outside: "Xiaobai! Xiaobai! Oh no! The wind direction has changed!"

The wind has changed?

Gu Xiaobai's brows furrowed, and then he listened to it.

Sure enough, the wind is not right, and the wind is against the wind!

Seeing Gu Xiaobai coming out of the room, Wang Guanshan grabbed him and said, "Xiaobai, it's against the wind, what should we do?"

Wang Guanshan has also seen a big scene.

Before, I followed Gu Xiaobai, and even the interior of Typhoon "Moby Dick" broke through.

But at this time, he was still uneasy.

There is no way, if the "Sea Dragon Palace" cannot arrive in Semarang on time, all the efforts they have put in before will be almost in vain.

Gu Xiaobai turned his head to look out the window, and saw that all the open "sails" of the "Sea Dragon Palace" had been retracted, and now the entire huge Sea Dragon Palace had restored the appearance of a stadium with a wave.

Gu Xiaobai could feel that the "Sea Dragon Palace" was actually not stationary now, it was actually on the sea, and it was blown backwards by the wind.

Although the speed is only about two or three kilometers per hour, it is indeed retreating.

In the square outside, there were many people talking to each other.

Some of them are construction workers who are responsible for the later construction on the "Sea Dragon Palace".

Some are experimenters from various collaborators doing experiments.

And there are also musicians who are rehearsing and competing at the "Sea Dragon Palace".

The others are okay, after all, it has nothing to do with them whether the "Dragon Palace on the Sea" can reach Semarang or not.

But most of the musicians looked worried and uneasy.

Shouldn't their job be in the soup like this!

If the "Sea Dragon Palace" does not arrive in Semarang on time, what will they do?

Will you lose your job?

Gu Xiaobai's brows also furrowed deeply.

His gaze swept over the "waves" that had been put together, and his brain was running at high speed.

"Xiaobai?"

Gu Xiaobai waved his hand and motioned to Wang Guanshan not to speak.

But at this time, how could Wang Guanshan not speak, he said: "Xiaobai, otherwise you will take the musician to Southeast Asia on the Zhongjun first......"

"Shhhhhhh

Wang Guanshan was really anxious, he stood in front of Gu Xiaobai and scratched his ears and cheeks, but he didn't dare to disturb Gu Xiaobai's thinking.

Gu Xiaobai's eyes blinked, drops of sweat flowed down his forehead, and his face turned red visibly.

A large amount of blood poured into his head and brain, and the whole person was sweating like rain.

Finally, Gu Xiaobai seemed to have completed some kind of calculation in his heart, and grabbed Wang Guanshan: "Let's go, go to the bridge!"

Wang Guanshan hurriedly followed, and he asked as he ran, "Xiaobai, what are you doing on the bridge now?"

Gu Xiaobai strode forward and asked Wang Guanshan, "Uncle Shan, let me ask you, is the sailboat fast with the wind or against the wind?"

"Of course it's a tailwind. Wang Guanshan replied without thinking.

During this time, Wang Guanshan was in Zheng He's fleet, as the deputy envoy Wang Jinghong, commanding the fleet all day long, considering the wind direction every day, and adjusting the direction of travel, which has become instinctive.

"Wrong. Gu Xiaobai denied Wang Guanshan's words.

"Could it be that the headwind is faster?" Wang Guanshan felt that Gu Xiaobai must be stupid.

How is this possible!

How to sail against the wind!

There is an idiom in China, called "a smooth journey", doesn't it just wish others a smooth sail and a fast sail?

If you go against the wind all the way, I'm afraid you're going to die of exhaustion?

The thought that his fleet might encounter headwinds, Wang Guanshan's hair had to fall out a lot.

"With a normal sailboat design, it's naturally faster downwind. Gu Xiaobai explained, "For sailboats, under the same length-to-width ratio and shape, the longer the waterline, the higher the upper speed limit of the sailboat, so the larger the ancient sailboat, the higher the upper speed limit......"

Wang Guanshan knows this, many times, in order to maintain the overall speed, the oversized treasure ship cannot be fully sailed.

"But in this case, the wind speed is the upper limit of the sailboat's speed...... But there is another way to make the speed of the sailboat several times the speed of the wind!"

"How is it possible!" Wang Guanshan shook his head: "I don't read much, don't lie to me!"

I also studied physics!

The wind is so fast, how can a sailboat be faster than the wind speed!

That's impossible!
