One evening a few days later, Nicole came to Gu Jin's recovery ward and brought him the news that she had met your wife and daughter, and told them how you were doing with a video of your recent life.

“…… How are Xiaoxue and Taotao doing? ”

Gu Jin's focus is obviously different from Nicole's.

"What else? They didn't seem to be in a good mood, but when I met them, they were walking on the rainy streets with umbrellas. ”

Gu Jin: "......"

"Don't worry, you can see that they are a very strong mother and daughter......"

"Whatever they decide, I can understand it!"

After Gu Jin said this, he lowered his head and sighed softly.

"Hmm...... A week after the first meeting, I gave your handwritten letter to your wife, as well as your second video, I think, these few days are enough for their mother and daughter to digest, and we agreed to reply in three days. Don't be impatient, have a good rest, you have a long way to come! ”

Nicole looked at Captain Gu, who was holding back tears, and suddenly felt a little sad, and quietly left the room after whispering these few words......

Time flies quickly, and Gu Jin has been groping on this 10,000-ton ship for four days.

At this time, he was standing in the wide cockpit, talking to a young man in a seafarer's round-necked sweatshirt, the young man turned the steering wheel, looked up at Captain Gu who was standing in the window of the cockpit in a daze, hesitated for a moment, and finally whispered to Gu Jin:

"Captain, today is the fourth day, isn't it?"

"Hmm."

"I think...... Aunt and Peach ......"

"Sanduo, we need to check the steering wheel motor, we should reflect it to Anna, and give us a few more spare ones!"

Gu Jin interrupted the young man's words and turned back to the young man.

However, the young man did not seem to listen, and suddenly pointed out the window in a slightly excited tone and said:

"Captain! Nicole is back, and I see she's just on the foredeck! ”

Gu Jin glanced at the young man's fingers, then immediately left the window and hurried to the gangway of the cockpit, but then he suddenly remembered something, and said to the young man without looking back:

"Sanduo, you get familiar with it first, I'll come back when I go!"

Before he could finish speaking, the man disappeared into the cockpit door

"Okay, Captain......"

Whispering in response, a smile tugged at the corner of the young man's lips, his eyes turned to the cockpit door, and he watched for a moment before continuing to turn his attention to the steering wheel in front of him.

Captain Gu is his old boss and the noble man of his life.

Probably because of the same background in an orphanage and the reason why he can endure hardships, Li Sanduo has been cared for and supported by the captain since he graduated from the navigation school and was assigned to Gu Jin's ocean-going steamship as an intern.

Of course, he knew what Captain Gu had been thinking in the past few days, and Gu Jin didn't hide anything from him, after all, the friendship between the two far exceeded the relationship between colleagues and seniors.

Since Li Sanduo was many years younger than Gu Jin, his body recovered much faster than Gu Jin, and he had been groping around on this ship since a week ago, not only that, but he was also very interested in the brig next to him.

This is a well-known brig, and Anna named it "Pride", which matches the pride and superiority that Anna herself always shows when she receives people and things, consciously or unconsciously.

Anna is also said to have been the refitter of the ship. Nicole once told him that Anna was originally a ship fan, and since she traveled to this era, she likes to play with ship changes and even personally designs ships and ships shipbuilding, so these two ships have a lot of traces of Anna's transformation.

Li Sanduo also learned from Anna that the steam-powered unit of the Pride was not a traditional steam engine and propeller transmission system, but a jet drive method with an external combustion engine and a high-pressure gas storage tank. Listen to Nicole, this is also Anna's masterpiece.

However, this unconventional drive method also made Li Sanduo a little doubtful about the endurance of the Pride.

As it turned out, his worries were not unfounded, and the Pride was powered by three 50-kilowatt Stirling external combustion engines, but instead of a whole ship without propellers, it relied on three engine-driven air compressors to fill the tanks with compressed air, which was then driven by high-pressure gas control emissions.

It seems that although the power is sufficient and the speed can be increased in a short time, there is a big problem with this type of propulsion: if the ship is driven by this alternative form of power, the endurance will be seriously insufficient.

Li Sanduo believes that the pure mechanical power of this boat may be able to run at a high speed of ten to twelve or three knots, but this drive mode has a big disadvantage: because it cannot continue to generate power like a propeller, after a period of time, the air storage tank must be re-inflated, otherwise there will be no air pressure.

Also, the three 200 hp Stirling engines are a bit larger and heavier, which takes up a lot of payload. Of course, the most important thing is that the power may not keep up with the speed of air emissions, and after a period of operation, you must stop and inflate at full strength. Obviously, the thermal efficiency of the external combustion engine is not high, and the engine room is crowded, so that the payload of this sailing ship with a displacement of more than 1,000 tons is actually less than 500 tons!

This has a lot to do with the fact that the three Stirling engines and the gas tank system take up a lot of load.

When Li Sanduo raised his concerns about Anna, Anna's attitude was a little disapproving, and he responded in a resolute tone to him that he was an environmentalist and hated propellers very much, so he would not use the propeller power system in order to save load, not to mention, a payload of about 450 tons was already quite a good payload three hundred years ago, right?

However, looking at Li Sanduo's scrutinizing expression, Anna sighed and further explained, this kind of engine has a simple structure, and it is relatively easy for you to copy it, don't I know how to use an internal combustion engine to increase power? It's just for you to make it easier for you to copy!

Anna once told Li Sanduo very seriously, don't expect to give you industrial equipment to build an internal combustion engine quickly, to be honest, it would be good if you could build an external combustion engine in the short term.

Don't believe it, you really can't build something like an internal combustion engine quickly, even if you are given industrial equipment, it will be in vain! Because the era you went to was simply not able to support the modern industrial system, everything you have to start from the beginning, and then you can gradually meet the conditions and develop slowly!

As for the boat's performance, Anna assured Li Sanduo that although the boat has a rudder, it can rely on the jet system on the flanks of the hull to steer in an emergency, so the steering agility is excellent.

And the pressurization of the gas tank can maintain the driving force for about eight hours at a time, think about it, in the event of a naval battle, you can have eight hours to move flexibly regardless of the direction of the wind, what an advantage is that?! Therefore, as a sailboat, it should be excellent to have such auxiliary power.

Especially in the era that you will travel to, three hundred years ago in the seventeenth century, on the eve of the Industrial Revolution, you can drive a hybrid sailboat that embodies the scientific and technological achievements of the first industrial revolution and gallop across the ocean. Be content......

In fact, there is no need for Anna to say that Li Sanduo is also very content, thinking that at the beginning, although he graduated from the navigation school, his professional direction was steamship, and he did not have much contact with sailboats, but fortunately, Gu Jin was an expert in these two aspects, and Li Sanduo was also diligent, in the past days, he learned a lot of sailing knowledge from Captain Gu.

It's just that he hasn't had time to realize his ideal of "buying a sailboat to travel around the world when he earns enough money", he was brought here by fate, and now, he is unexpectedly about to realize the ideal of driving a sailboat to gallop the ocean.
