Lin Hua's ship construction drawings not only designed with water-sealed cabins, but also equipped with a bulbous bow for the warship ships.

In fact, water seal cabins have appeared in China for a long time, but they were not there in the West at that time.

The main purpose of "bulbous bow" is to reduce the wave resistance and increase the speed of the ship when sailing.

The resistance of the ship when sailing mainly comes from two aspects: one is the frictional resistance and viscous resistance between the hull and the water, and the other is the resistance of the waves and the waves when the bow cuts the waves.

The hull is designed with a streamlined shape to reduce the friction and viscous resistance formed by the viscosity of water; the installation of the bulbous bow is to reduce the wave-burning resistance and wave-breaking resistance during navigation.

When there is no bulbous bow, the bow will cause a large wave of water and create greater resistance?

If a section extends forward of the bulb's bow, it can first stir a water wave, and then the water waves stirred by the bow can only be 180 degrees in phase.

This can offset it with the intention, thereby significantly reducing the resistance to the rising wave.

In that era, Western ships did not have water seal cabins. It can be said that China was about a century earlier than the West in this regard.

The water-blocking technology of Western ships also imitates our Chinese ship construction technology.

Ships in China in the Tang Dynasty had watertight compartments, which were only available in Europe in the 18th century.

The watertight compartment structure used by Chinese ships has been appreciated by foreign countries for a long time.

In his "Travels", the Italian executor of the Yuan Dynasty, Marco Polo gave a detailed description of Chinese ships.

Bensom, England, once inspected China's ship structure, improved Europe's shipbuilding technology, and introduced China's watertight compartment structure.

In 1795, he was commissioned by the Royal Navy to design and manufacture six new types of ships.

In his paper he wrote, the ships he built "has increased strength partitions, which protect the ships from entering and sinking, just as the Chinese do now.

"Later, Mrs. Benthum pointed out in her biography for her husband: "This is not the invention of General Benthum.

He himself once said publicly, 'This is what the Chinese today are doing, just as the Chinese in ancient times'.

"From then on, China's advanced watertight compartment structure has gradually been absorbed by shipbuilding technology in Europe and around the world.

It is still an important structural form in ship design.

Lin Hua did not have a shipbuilding background before. After being caught by the Dutch people in Badaveia for work, he gradually became an outstanding ship construction engineer.

Seeing the design drawings of the bulbous bow and water seal cabin, he immediately felt how much it would have to promote the progress of the Galen ship.

As the second overseas territory of the Ming Dynasty, Zhu Youjian still has to go and see it.

Zhu Youjian led a large army of land and sea boarding the ship, and the fleet left Huangming Island and rushed to Malacca (Malaysia in later generations)

Two days later, the fleet arrived at the waters near Malacca. Zhang Huangyan and Li Dingguo had already received a report from the emperor that he wanted to come to Malacca.

For the sake of the safety of the emperor, they immediately ordered martial law near the port, and the Longteng Army sailed five steps one by ten steps one by one and a sentry.

Some Chinese in Malacca and local natives who work and pass by are limited to 500 steps away.

Then the two of them led their soldiers to greet each other at the port and waited for two hours before they saw the Ming fleet enter the port of Malacca.

Zhu Youjian stood on the deck of Dayu, looking at Malacca City in front of him, with a sincere smile on his face.

The Strait of Malacca, which later generations were boring against China, now belongs to the Ming Dynasty.

"Your Majesty, the fleet has entered Malacca HNA, and Zhang Huangyan and Li Dingguo are waiting at the port."

Zheng Chenggong and Qi Jiguang, who were standing next to Zhu Youjian, pointed at the two people on the shore and said to Zhu Youjian.

Zhu Youjian nodded:

"Well, I'll send an order to let the soldiers log in and rest for a day, and then replenish the fleet in Malacca."

"Abide by the order"

The decree was quickly conveyed. Surrounded by generals such as Qi Jiguang and Zheng Chenggong, the Chinese emperors ascended the land of Nanyang for the first time.

After getting off the ship, Qinglong Cao Zhengchun walked left and right before and behind Zhu Youjian

Jinyiwei and Dongchang Fanzi surrounded the emperor in the middle, pressing the hilt of Xiuchun's knife with his hands, looking around vigilantly.

Once they see someone who is not good to the emperor, they will stand up as soon as possible and let those people meet the King of Hell.

Seeing the emperor landing, Zhang Huangyan and Li Dingguo hurriedly stepped forward and bowed:

"I am accused of Zhang Huangyan and Li Dingguo to meet His Majesty."

Behind them, the soldiers followed and bowed:

"See Your Majesty!"

Zhu Youjian raised his hands slightly and smiled:

"Thank you for your hard work, please don't give me a favor!"

"Thank you, your Majesty, long live my emperor!"

Some Chinese in the distance were already shocked by the overwhelming warships at the port. They had never seen so many tall and giant ships, let alone iron-armored warships.

It was not until the sound of shouting long live from the port that they realized that His Majesty the Emperor of the Ming Dynasty was in person to Malacca.

When they left the Ming Dynasty, the Ming Dynasty was experiencing internal and external troubles, coupled with natural disasters, causing refugees everywhere.

At that time, the Chinese in Badaveya and Luzon were massacred, and the Ming Dynasty itself could not protect themselves, of course they could not control their lives and deaths.

Now I heard that the Ming Dynasty had strongly suppressed the East and killed bandits, expelled the Portuguese in Macau, and eliminated the Netherlands invaders in Taiwan.

Vigorously developing industrial agriculture and foreign trade have entered a prosperous era.

Some time ago, I heard that the Badaweian Netherlands and local natives massacred Chinese again.

This time was completely different from before. The Emperor Ming Dynasty was furious and immediately sent troops to attack Badavia.

He strongly killed Governor Badaveya and defeated Lan Diguo against Bandanma.

The Batavia region and the entire sea area have now been included in the Ming Dynasty.

I thought that such a great and godly Emperor of Ming Dynasty was just a legend, and they would never have the chance to see it with their own eyes.

Who would have thought that the legendary emperor of the Ming Dynasty could actually visit the little Malacca, and would not have thought that they would actually see the real person.

Chinese people in Malacca knelt on the ground and kowtowed to Zhu Youjian in this direction:

"Thank you, His Majesty the Emperor of the Celestial Empire, for sending heavenly soldiers to rescue us overseas Chinese. Long live His Majesty the Emperor of the Celestial Empire!"

Seeing so many Chinese people slumped not far away, Zhu Youjian was also excited. He knew that this was his recognition and gratitude to him as an emperor.

With his hand stretched out his hand to separate the many guards around him, Zhu Youjian went directly to the Chinese outside the circle layer by layer.

"Your Majesty, you can't. The Ming Dynasty has offended too many foreign devils and natives during this period. Safety is the best!"

Qinglong Cao Zhengchun hurriedly stopped Zhu Youjian, who were worried that some people would be unfavorable to the emperor.

Zhu Youjian smiled slightly:

"It doesn't matter, I believe they are all good people."

"Your Majesty, what the Superior Lord and the commander of Qinglong are reasonable, it's better to be careful..."

Generals such as Qi Jiguang and Zheng Chenggong also advised the emperor that they were worried about His Majesty’s safety in this unfamiliar place.

As soon as the Ming Dynasty was on track, the emperor led the army to the army. If something unexpected happened, no one could take on this responsibility.

Zhu Youjian's face turned dark:
