Long Hao smiled: "I knew you would ask this, well, I naturally have my reasons. I want to use this submarine recently... Today, John, just try this diving dragon with me-

On the 1st, see if there are any major mistakes. If there are, there is still some time left, and we can try our best to correct them."

The big mistake naturally refers to the submarine's underwater pressure resistance. No matter how many sources of Long Hao's gold, he cannot let a leaky submarine continue to sail under the sea.

When Holland heard this, he muttered, but he nodded and said, "Okay, everything is listened to you... At present, it seems that the surface navigation of Qianlong-1 is basically normal, and the current speed has also increased to 12 knots, which proves that

The internal combustion engine motor is working well."

Long Hao also nodded and said, "The normal surface navigation is just the beginning. What is really important is the underwater navigation. Come, Mr. Holland, let's go together!"

After saying that, the two men, under the escort of a sailor, opened the hatch and entered the interior of Qianlong-1 in turn.

This time, the interior of Qianlong-1 has been filled with fullness. The components missing last time have been filled and the white lines are no longer visible.

Today, Qianlong-1 has a displacement of 120 tons, a self-weight of 78.5 tons, and can accommodate up to 8 crew members.

At this moment, because it was a trial sailing, in order to ensure spaciousness and comfort, except for Long Hao and Holland, only three sailors stayed in their respective positions.

One is responsible for manipulating the direction of travel, one is responsible for adjusting the power switching and up and down, and the other is the sailor who has just come down, who is mainly responsible for maneuver (well, including excitement).

Long Hao stood behind the sailor who was responsible for controlling the direction of the journey and asked, "How is the steering function of Qianlong-1? Haven't tried it yet, so start the experiment now!"

Just now, Long Hao and Holland were standing on the top of the submarine, and they definitely couldn't try steering or something, so at this moment, the sailor responded with great energy and started to control it with concentration, and soon. Qianlong-1

The number started to turn.

Although Qianlong-1 was turning, the boat was not affected much. This experimental result surprised Holland and others. Only the old god Long Hao was determined: Just kidding, this has been tested countless times in the future.

Although the best submarine form is inevitable in my hands, how can the steering at such a low speed affect the inside of the ship?

After the test, the steering was turned, and then dived. This test was the most important. Except for Long Hao, the other four people in the boat seemed a little short of breath.

Long Hao smiled and said, "Don't be nervous. With me, the young master, I, even if Qianlong-1 can't float up after diving, I will rescue you safely."

As soon as these words came out, everyone's mood immediately calmed down.

After all, Qianlong-1 was too hasty from appearing to going into the sea, and any sailor suddenly had to dive into the depths of the ocean with the ship. He felt a little scared.

The sailor in charge of controlling the scuba and float immediately raised his chest and said, "I am afraid of death and not joining the army. It is our honor to be able to dive with the young master!... Report, the speed of the Qianlong-1 is zero, and now it starts diving, internal combustion engine

Stopped. The power switches to electric motor to start..."

Above the dock, Kunpeng's technicians, the left-behind Dragon Scale Navy, Zheng Tingxiang and his gang who were strolling out, and the heart-wrenching Yuan'er... In short, in the Kunpeng shipyard, all those who could gather were gathered here, if it weren't for the dock

Not wide enough. I'm afraid that these people will crush the dock if they squeeze in!

They all watched Qianlong-1 drive away with expectations and nervously. This trial voyage touched everyone's hearts.

Someone asked: "Can a ship sink to the bottom of the sea be true or false? Can a ship sink to the bottom of the sea still be called a ship?"

Someone answered: "As soon as I heard, I knew you didn't listen to the young master carefully. Of course that guy is not called a ship... that's called a submarine! Submarines, as the name suggests, are naturally ships that can be submersed!"

The man asked, "Didn't all the submersible ships have entered the water? How did they float up after entering the water?"

The man replied: "Fortunately, I participated in the transformation of this Summer Dragon-1. Your problem will not make me difficult. It is very simple to float. Just drain the excess water from the water storage compartment in the submarine. I will go with you.

Tell me, have you eaten fish? Have you seen fish maw..."

The voices of people are endless. Although most people have been engaged in the shipbuilding industry for their whole lives, the submarine is still too high-end. If foreigners may have heard of it, it is undoubtedly for the yellow-skinned and dark-haired Chinese.

Things are coming from outside the sky.

Novelty, novelty everywhere.

Submarines are also novel to Zheng Tingxiang. He has been in the United States for decades. Even though he has almost integrated into this immigrant country, built bridges and covered buildings, he has heard of submarines today.

This is the first time I have seen a real thing.

Can such an iron lump really pretend to be a person and sneak into the sea?

By the way, Zheng Tingxiang had some small opinions about Long Hao before: I am a American mechanical engineer, abandoning the career I worked hard in the United States, obeying the advice of my classmates, and coming to join you, but you are fine, I didn't follow me from beginning to end

I talked alone and didn’t give me the attention I deserved.

A young child like Zheng Tingxiang, who has worked hard in a foreign country since he was a child, has a high degree of self-esteem and spiritual sensitivity. Therefore, although he is a 'scientific intellectual', he is actually similar to an ancient Chinese strategist and needs a lord's lord.

Respect and courtesy.

But over the past few days, Zheng Tingxiang's attitude towards Long Hao has changed a lot: he saw Long Hao and the ship workers fighting together, working hard all night for the successful trial sail of the Qianlong-1 ship, without any pretentiousness.

, able to get along with the workers at the bottom, and although he is young, he has a wide range of knowledge. Many of the problems encountered during the transformation of Qianlong-1 were not solved by Holland, and in the end, Long Hao came up with the idea to solve them.

Some solutions, such as the creativity of the double-layer shell structure of the submarine, originated from Long Hao and Zheng Tingxiang, after hearing this, they also exclaimed strange ideas and were amazed.

(Note: Double-layer shell structure, that is, the submarine consists of an inner and outer shell, and the middle space is filled as a ballast water tank to control submersible float and improve seaworthiness.)

Zheng Tingxiang's "staff cloak" was originally thin. Under Long Hao's sincere actions, it quickly disappeared.

During the process of transforming Qianlong-1, Long Hao also asked Zheng Tingxiang about many mechanical engineering issues. This kind of agile and studious spirit is also very fond of Zheng Tingxiang's appetite.

Zheng Tingxiang was still a scholar after all, and he also knew Long Hao's amazing innovation in physics. Therefore, after several exchanges, his small opinions on Long Hao disappeared, and he felt that only Long Hao respected him like this.

Only leaders who have science and practice it can lead the Chinese nation out of the quagmire that has been deeply trapped in hundreds of years and regain its former glory.

After all, before he knew it, Zheng Tingxiang was "submerged" by Long Hao, but... he still had a reservation about Long Hao's bold study of this "submarine".

In Zheng Tingxiang's view, Long Hao's establishment of the Kunpeng Shipyard is undoubtedly a correct way of chess, while building a submarine is a bit like creating a robbery and circling around his side with "scarce wealth".

Shipbuilding, especially building iron-armored ships that can sail from ocean and win sea battles, is the current trend, don’t you see. How was the British Empire established? Didn’t it rely on its strong naval support?

Germany understands this, Japan understands it, and the United States understands it!

Zheng Tingxiang, who is half an American, is also very clear about this, so when Rong Shangqin invited him, he immediately lost his job and took his team to the sky.

Come and join us.

Rather than saying that Long Hao's legendary story touched him, it is better to say that the bright prospects of Kunpeng Shipyard attracted him. Zheng Tingxiang understood that the Chinese nation wanted to rise. He wanted to truly stand on the peak of the world's national forests, on the ocean.

This lesson will be made up sooner or later. It is imperative to build large ships, gunships, and solid ships.

It was with this idea that, when Long Hao threw out the "Short Record Pavilion", Zheng Tingxiang would regardless of gains and losses, bury them all in sorting, sorting, and explaining these precious shipbuilding materials, because he believed that with these

, Kunpeng Shipyard has hope of catching up with the European powers!

At least...it can gain a foothold on the West Coast of the United States.

However, under the good situation, Long Hao suddenly became "unemployed" and spent his best efforts to conquer a "submarine designer" who even the US Navy doesn't want. Not only that, he also took the lead in dealing with the name "Holland" named "Holland".

The designer was joking and summoned a large number of boat workers. In just a few days, he knocked and pushed a boat that didn't look like a boat or a boat down the sea!

Zheng Tingxiang sighed and remembered what Long Hao said to him: "Yun Yao, don't underestimate the submarine. We want to defeat the European powers and fight for the right to speak at sea, and it depends on it!

There was no big problem with this trial voyage, so I would let Kunpeng Shipyard concentrate on producing such submarines in large quantities!”

Young Master Long still needs to build a submarine on a large scale?

Zheng Tingxiang was very confused. He felt like he was watching his ex-girlfriend go astray in order to live a better life, but he was powerless... He knew that Long Hao was taking a 'wrong' path, but he couldn't go.

dissuade.

Thinking of this, Zheng Tingxiang's eyes returned to the sea and back to the gradually smaller Qianlong-1.

Perhaps, this trial voyage will fail...it's better.

A thought suddenly popped up in Zheng Tingxiang's heart that he could not even imagine.

"Look, it's sinking, it's sinking!"

Zheng Tingxiang's complicated thoughts were interrupted by a loud scream. He quickly looked up and found that everyone around him raised his hands and shouted like crazy. Qianlong-1 at the end of the sea level was suddenly down.

Hidden! At this moment, the hull has disappeared, and only the shadow of the hatch can be vaguely seen.

"What is it called sinking? It's called diving. It's the submarine that actively dives into the sea... The shipwreck is called sinking. It's not cultured!"

"You know a lot, then tell me, can the submarine float up after diving?"

"Of course you can float up, otherwise, isn't it a death to dive actively?"

"Why didn't you see it floating now? It's been a few minutes now, and people can't suffocate to death in the water!"

"Hey, you don't admit that you are not educated! After the submarine dives, it can continue sailing. How could it float up in place? Wait, maybe it floats up in front of you with a thunderous sound.

You jumped!"

"So that's it... Humph, don't think you'll be proud if you pass the third-level boater exam. Besides, I'm not educated, I'll beat you up!"

...

Inside the cabin of Qianlong-1.

"Report, the diving depth is 20 meters...30 meters...35 meters..."

"Earl. Is it almost done? 35 meters is enough."

Holland listened to the sailor reporting the parameters and said to Long Hao nervously.

The current submarine is already quite amazing to dive 20 meters, but now Long Hao has nearly doubled the dive depth of Qianlong-1. How can this not make Holland feel like a deer?

The pressure of the sea water is not a joke. If the submarine's shell breaks and the sea water pours in, we will all press into meat pies!

"No hurry, I guess 50 meters is probably the limit... Uh, hehe, John, your face is pale, OK, stop diving, what is the depth now?"

Long Hao teased Holland and finally issued an order to stop diving.
