"Of course you can. However, our boat collided with someone else's boat a few days ago during the test, and now it needs to be repaired. Wait about five days, I don't know if you have time to wait? Yu Ren didn't have such a ship, but he had already begun to have a little idea in his heart. He believed he could make something different. However, it will take time. He decided to take over the business first and come back to figure out what to do. As long as the business continues, he believes that he must have a way.

The historian thought about it. "Yes, I haven't left in five days. However, it can't be delayed any longer. Otherwise, I should go back to Shandong. ”

"No problem, five days guarantee to fix the boat for you, so that you can see a clipper boat that you want, but never saw before." Yu Ren said confidently.

"Okay, then I'll come back in five days. See you here! Just in time for on-site sea trials. Shi Yuanwai was also mobilized by Yu Ren's emotions. It seems that he has seen the scene after his maritime business expands several times in the future.

"It's a deal!"

Except for sending away the excited historian, Sun Menghu and the three of them were worried. Because they know Yu Ren too well. They almost grew up wearing a pair of pants! When it comes to things like reading and writing, writing poems and paintings, Yu Ren is also good at it. But when it comes to shipbuilding, Yu Ren can't do it.

I've never heard of Yu Ren learning shipbuilding! Although he has been studying for more than half a year recently, I don't know what he has learned and what he has seen. However, this shipbuilding skill cannot be learned in a day or two. Sun Menghu knows this better than anyone else. When he first learned shipbuilding, he had studied it for almost two years, and he had only learned some of the surfaces, and he had not yet learned many real stunts. The two boats in front of him were almost the largest ships he could build, and no matter how big they were, he couldn't build them.

"What now?" Tian Jia asked. He asked Yu Ren, but his eyes were on Sun Menghu, obviously he didn't have much confidence in Yu Ren.

"What to do! Naturally, it's a hands-on approach! Five days can go by quickly. If we come back from the Historian, we won't be able to make a boat that will satisfy him. This business is yellow. Yu Ren said.

The three of them agreed, but they still looked at Yu Ren with a confused expression. "But, Brother Ren. We don't know how! We've never seen a ship like this, right? I've never even heard of it! ”

Yu Ren laughed. "I'm to blame for this. It's that I didn't make it clear to you. I've seen this kind of boat, and it's so fast. Sails are not needed at all. However, our current conditions are limited, and we can't make an exact one like theirs. Let's just borrow some of the stuff from it and make a slight alteration of our ship to make a ship that is faster than a normal ship and doesn't rely primarily on sails. This historian will definitely place an order. ”

The three of them heard that Yu Ren had seen such a boat. I was a little relieved.

"That's it. When it comes to shipbuilding, I'm an amateur. I will tell you about the main differences between the ships I have seen and our current ships, and then draw a picture. It's up to you to transform. Yu Ren said as he squatted on the ground and drew on the sand.

He first drew a propeller on the ground, and then several gears for transmission. Because he knew that in this day and age, there was no steam engine, that is, it was necessary to use human or animal power. In this way, he had to find a way to save effort from the lever and change the direction of the gear drive.

Then, he drew another pamma wheel. Yu Ren knew that early European ships were equipped with this kind of paddle wheel, and later they were gradually replaced by propellers.

Because Yu Ren drew the parts one by one separately. Therefore, Sun Menghu and the three of them didn't understand it for a while. Yu Ren explained to the three people the role of the propeller, the role of gears in transmission, and the principle of levers. Some of the three of them were skeptical, after all, they had never touched these things. In fact, in this era, many of the machinery of the Ming Dynasty have begun to use levers to save effort, and even some things are exquisitely made, which makes Yu Ren, a modern person, marvel at it. However, no one has ever summarized the principle of this. In addition, Sun Menghu and the three of them have never touched these machines, and they can only build ships.

In the end, Yu Ren told the three of them about the role of the bright wheel. This is easy for the three of them to understand, because there is a waterwheel! The wheeled waterwheel is very similar to this.

Seeing that the three of them couldn't understand it for a while, Yu Ren had no choice but to design it himself. After all, there are only five days left, if you slowly teach them first, and then let them do it. I'm afraid that the daylily will be cold. They can only do it while letting them understand the mystery.

So, Yu Ren left the three of them behind and went to work on his design alone. He had to figure out how he could load the propeller onto a large ship and still be able to pull it with the existing humans or animals. It's a bit difficult. But he didn't need the boat to be powered entirely by the propeller, or how fast it was, all he needed was to be able to add some power to the boat so that it could run faster than the average boat. It's a lot easier.

Yu Ren has also been on a sea boat many times. He knew that, in fact, some of the larger ships of the Ming Dynasty had already installed some devices that could be assisted by people on the lower deck. It's just that these artificial assistance is only rowed by boat pulp. It's inconvenient and laborious.

After studying for a long time, Yu Ren finally completed the sketch. But when he showed the sketch to Li Menghu and the others, the three of them agreed in unison that this design could not be installed on their ship at all. The reason is very simple, because their boat is not wide enough, and the device designed by Yu Ren would not be able to walk away at all if the boat was pulled by a mule.

Now Yu Renke was worried. Seeing that the sun had set, they didn't have much time left. What to do?

Looking at the afterglow of the sunset disappearing into the distance little by little, Yu Ren suddenly slapped his thigh. "Okay, that's it."

All three were taken aback by him. "How?" All three asked at the same time. They're in a hurry! Five days is too short to even make a boat.

"That's it! Huzi, you are responsible for borrowing a boat immediately, and if you can't borrow it, buy one. You want the old one, not the new one, just be able to get into the water. I have no silver, and I have eighty taels there. The boat should be able to seat two or three people, and the big ones should not be.

Tian Jia, you immediately go find a blacksmith shop and make one according to the picture on this picture. Remember, be sure to be strong.

As for Yoo Hee, you will follow me so that there is something to do at any time.

Huzi and Tian Jia took the order and left. At this time, in the deserted garden, the sunset was no longer visible. But the sky can still be seen for the time being. Yu Ren sent Huzi and Tian Jia away, and sat cross-legged on the beach and fell into deep thought......

I don't know how long it took.

"Brother Ren, Brother Ren!" Liu Xi's call finally woke up Yu Ren who was in deep thought.

"Ahh What's wrong? Yu Ren came to his senses and suddenly found that it was already dark all around, and by the moonlight, he could barely see Liu Xi in front of him.

"You're not coming home today?"

Only then did Yu Ren remember that he had slipped out.

"Forget it, don't go back. Time is urgent, let's wait for you to take this order first! After speaking, Yu Ren walked to the grass shed on the side.

This hut is built here by them, and sometimes it is inconvenient to live temporarily. The hut is not large, with only one bed and a small table. There was no chair and stool, so Yu Ren sat on the bed.

Seeing a pair of ink fountains on the table, Yu Ren suddenly remembered that he should draw what he had in mind. So he took out a tael of silver and handed it to Liu Xi.

"Go buy me some paper right now. Then get an oil lamp and some food by the way. We're going to fight tonight! ”

Yoo Hee agreed and turned to go. Suddenly, Yu Ren was the only one left in the dark grass shed. He suddenly felt a loneliness that he had never felt before. He felt like a millionaire with a million, in a poor country deep in the mountains, although there were millions, but there was nowhere to spend them. It's a really uncomfortable feeling.

"Or, just get a steam engine out!" Yu Ren said to himself.
