As the Giant Kun surfaced, Chu Tianshu gradually saw the whole picture of the Giant Kun. The overall shape is similar to that of the previous submarine, with an elliptical streamlined shape, wrapped in black iron sheets, and stabilized with dense rivets. It is more than three zhang long, one zhang wide in the middle, and slightly narrower at the beginning and tail, only four feet.

On both sides of the Giant Kun there are long wings, and above the wings extend a black hose with the thickness of a thumb, I don't know what material, similar to the glue water pipe in the previous life, a total of more than 20, it seems to be very long, more than six zhang, and the end is connected to a black float the size of a human head, and there is a hole in the float.

There was a round hatch at the top, which opened in a few moments, and out of it emerged an old man dressed in a black robe with a white goatee.

The old man looked at Chu Tianshu at first glance, because only Chu Tianshu was a stranger.

Then he respectfully bowed his hand to Chu Tianshu.

"The old man Yi Chaodong, I have seen the giant!" The old man said respectfully.

"Old gentleman doesn't have to be like this!" Chu Tianshu was very flattered and wanted to stop it, but unfortunately it was inconvenient to stand on the boat.

"Mr. Yi, hurry up and let the giant enter the Giant Kun! Recently, I don't know why the imperial court, there are a large number of buildings and ships patrolling in this sea area! Liu Qingyang said.

"Giant, please come in!" Yi Chaodong hurriedly said.

Because the Giant Kun was more than a zhang high after it surfaced, and there was no ladder to climb, but now Chu Tianshu's bouncing ability was not weak, and with a force under his feet, he jumped onto the Giant Kun, and then entered the cabin.

When entering, Chu Tianshu took a closer look at the top hatch, and saw that there was a black soft substance in the corner, which seemed to have good air tightness.

There was a staircase going down the hatch, and Chu Tianshu quickly entered.

The space in the cabin began to be large, and there were more than a dozen people inside who were adjusting the air pressure inside the Giant Kun. These people are all children of the Mo family, all of them are middle-aged, and there is no young existence, which shows that the skills of the Mo family, young people have not yet mastered it.

After a while, Yi Chaodong, Kuai Pingyuan, Liu Qingyang, and Lu Fenming all entered the cabin.

The hatch was also closed.

"Into the water!" Yi Chaodong ordered.

Immediately, the children of the Mo family in the cabin began to operate.

A person on both sides moved the switch, and suddenly the flanks of the outside world were deflected forward, and someone at the tail kept rotating a wooden rotating rod, with thick ropes on it, and with the rotation, bursts of exhaust sound continued to come out.

And the Giant Kun is also gradually sinking.

There is only space in the middle of the cabin, and there is no space at the end of the cabin.

Chu Tianshu looked at everything in the cabin curiously, since this is a world of cultivation, people's strength is very great, and they are very relaxed for physical work, and they will not get tired.

There was a man at the front of the cabin, constantly looking through a periscope-like object.

The rest of the space, in the middle is a bicycle-like device, there are a total of five positions, all of which are occupied by people, and as the Giant Kun continues to dive, it reaches a position of almost twenty meters, and these people begin to pedal hard, and gradually the Giant Kun advances.

The pressure in the cabin is actually very uncomfortable for both ears, but through the airtight adjustment, this discomfort is also eliminated.

For the Mo family's technology, Chu Tianshu admired it very much.

There are no other superfluous items in the cabin of the Giant Kun in order to reduce weight. However, there were plenty of dry food and drinking water.

In general, the Mo family's Giant Kun, the internal division of personnel is still very clear.

One person in the front adjusts the direction, one person watches, one person on each side adjusts the flanks, and two people in the front and rear adjust the air pressure. In the middle, there are five people who are the power source of the Giant Kun.

There is also one person who is Yi Chaodong as the main person who gives orders.

With the driving of the Giant Kun, Yi Chaodong came to Chu Tianshu and sat on the ground, and Liu Qingyang, Lu Mingming, and Kuai Pingyuan also followed.

"Giant, sit down! The speed of the Giant Kun is not very fast, and it will take at least half a month to reach the Organ Island! Yi Chaodong said.

Immediately, Chu Tianshu also sat down.

"Giant, it seems that you are curious about the Giant Kun?" Yi Chaodong asked.

Chu Tianshu nodded.

Immediately, Yi Chaodong smiled slightly and began to explain:

"The Giant Kun is the crystallization of the wisdom of the sages of the Mo family, and it was not completed until twenty years ago! After years of refinement, it is now perfect! Although there are still many shortcomings, being able to sneak in the sea is already a brilliant product of my Mo family, much better than those sour Confucian students who can only fool with their mouths! It can be seen that Yi Chaodong is very disdainful of Confucianism.

Chu Tianshu listened quietly, because he only understood the general situation, not a professional.

Yi Chaodong continued:

"The Giant Kun is three feet and five feet long, and the widest in the middle reaches one zhang and three feet. The inner cabin is two zhang long, one battle wide, and one zhang two high. The inner wall is made of special wooden boards, which is light and hard, waterproof and anti-corrosion; On the outside, the ink iron smelted by the secret method of the Mo family is extremely hard and can withstand the impact of the power of a thousand stones. In the end and end partitions, two main airbags are distributed, and the floats connected by hoses on both sides of the Jukun are used for exhaust and inhalation. That's why we can breathe safely underwater! However, due to the limited length of the hose and the bearability of the Giant Kun, it can only sneak six feet underwater. The flanks stabilize the balance of the Giant Kun, which will not be subverted, and there is also the power plant propeller of the Giant Kun at the tail, which can be rotated by the five people in the cabin at the same time, so that the purpose of moving forward can be achieved. But also because of the flanks, the speed of the Giant Kun can only reach a maximum distance of a quarter of an hour and ten miles! After speaking, Yi Chaodong's face was very proud.

Hearing this, Chu Tianshu thought of the speed of the submarine in his previous life. In the previous life, conventional submarines traveled at a speed of twenty-five knots per hour, which is equivalent to 45 km/h; And the Mo family's giant kun is 10 miles in a quarter of an hour, and an hour is 40 miles, which is equivalent to 20 kilometers per hour, such a speed is already very good, but this is only the peak speed, most of them are just more than ten kilometers, because they are all operated by manpower, and they are not ordinary people, they are controlled by some masters who have achieved cultivation, otherwise the speed will be lower! Moreover, the water level of the giant kun is not deep, so the speed can be reached like this.

In addition to being surprised, Chu Tianshu also admired the scientific and technological level of the Mo family, which was simply an epoch-making leader, and the wisdom of the ancients was worthy of admiration.

It's a pity that I haven't heard of the prototype of a submarine during the Han Dynasty in my previous life, perhaps because the Mo family was exterminated, so the technology was lost.

The doctrine of the Mohists seems to have been translated during the Qing Dynasty, and then it was studied vigorously. It seems that the Qing Dynasty also had the prototype of a submarine and built it, but the royal family did not pay attention to it at that time.

Immediately, Chu Tianshu asked some detailed questions, that is, how to wait and see the information from the outside world, because the cabin was a sealed environment and there was no window.

Yi Chaodong also explained that it is viewed through the water mirror, which is equivalent to a periscope, but the name is different, and there is a certain difference between the two.

Then came the dull voyage, Liu Qingyang, Lu Mingming and others gradually closed their eyes and recuperated, Chu Tianshu had nothing else to do, and began to cultivate.

Sometimes, Liu Qingyang, Kuai Pingyuan, Lu Mingming, and Yi Chaodong will also replace the five strong men who are the power source, so that they can eat something and rest to recuperate their spirits by the way.

And so the days went by.

On the other side, the Han Dynasty boat team that the Mo family saw was actually a naval army that went to help South Vietnam. The navy of the Han Dynasty was called Lou Chuanshi, which was commanded by General Lou Chuan.

The Han Dynasty's building boats could reach up to 10 zhang, but due to the center of gravity, they could only travel inland rivers. At sea, the size of the building ship is relatively small, but each building ship can carry 1,000 people.

In August, King Ying of Minyue sent troops to the border towns of Nanyue, preparing to conquer Nanyue. It's a pity that Nanyue immediately asked the Han Dynasty for help, so Emperor Wu of the Han Dynasty sent people to the rescue, this time sending ministers Wang Hui and Han Anguo to lead the troops.

Therefore, a large number of building ships have appeared on the sea one after another, so the people from Mojia Island will be late. The main thing is to hide, because the float on the Giant Kun is too conspicuous at close range, and it is not good to be noticed.

It's a pity that this time, it's almost the same as the last time, although the two sides are at war.

But the end was also fast, mainly in the Minyue Kingdom, Ying's younger brother Yu Shan was afraid of the Han Dynasty and took the opportunity to launch a coup d'état. He killed his elder brother Ying, and finally confessed to Emperor Wu of Han. So Emperor Wu of the Han Dynasty did not continue to investigate.

Let's not talk about these things first, Chu Tianshu took the Giant Kun and after more than 20 days before arriving at Mojia Organ Island. The main reason why the speed is so slow is that when he came to pick up Chu Tianshu, he had already come with his feet non-stop, so he was still very tired, so the speed of going back slowed down again.

Luckily, nothing happened along the way.

Mojia Organ Island is located in the East China Sea, nearly 10,000 miles away from the mainland. If you don't know the direction, you won't be able to find Mojia Organ Island at all. Moreover, there are reefs around Mojia Organ Island, and only fixed waterways do not have reefs. The Giant Kun is located in the water, making it easy to avoid reefs.

Moreover, the Mojia Organ Island is surrounded by mist, and it is impossible to discover the existence of the Mojia Organ Island from a distance.

As they arrived at their destination, Chu Tianshu and the others also landed.

Breathing in the fresh air of the island, Chu Tianshu suddenly felt refreshed. The Giant Kun is too dull, and the air circulation is not good, so I can only barely breathe, and I will not suffocate.

Mojiajiao Island is divided into inner islands and outer islands, because the outer islands are composed of some slightly smaller land in the form of a chain, and the inner island is a whole island with a radius of ten miles, and there is a small freshwater lake in the center of the island, which is the source of drinking water on the island.

The inner island is guarded by the outer islands, and there are various buildings on the outer islands, and it is not an exaggeration to say that there is only one building complex on the inner island, or a small town.

Chu Tianshu and the others landed on the inner island, and with the appearance of the Giant Kun, hundreds of people appeared in the city one after another, all of whom came to the dock.

Seeing the scale of Mojia Organ Island, Chu Tianshu was very surprised. This is no longer an island, and for decades, it seems to have developed into a small country by the Mo family.

The castles on the island of Mojia are called Mocheng, and they are all built of black rocks, and the momentum is very mysterious and mysterious.

The Mo family is mainly defending, so on the Mojia Organ Island, there are countless mechanisms, and even the calm underwater is full of murderous opportunities, if it weren't for the fact that it was the Giant Kun, as long as the organs were all opened, foreign enemies would not be able to get close to the Mojia Organ Island, let alone land.

There are also various defensive equipment on the outer islands, and the attack distance is far away, and it is very accurate and the error is very small.

These situations were all explained by Yi Chaodong to Chu Tianshu along the way.

Let's not talk about these first, the disciples of the Mo family who came out to greet them, all of them in black robes, were very neat, and everyone was arranged in a tight and orderly manner. Chu Tianshu understood that the disciples of the Mo family in history were all forbidden existences, and they were all loyal and not afraid of death.

Because of this, the children of the Mo family in history have used their lives to compose tragic songs.
