I have been farming since I crossed over.

Yang Mingxi raised the corners of her mouth slightly, revealing a bright smile, and whispered: "It's not really an inspection of your work, I just want to come and see the results of your labor!" Her eyes fell on Lu Qin, full of anticipation and curiosity.

Lu Qin also smiled and responded, "I wonder what you think? Are you satisfied?" There was a hint of uneasiness in his tone, as if he cared a lot about Yang Mingxi's evaluation.

"Of course I'm very satisfied! Otherwise, how could we rush here so early in the morning? Right!" Yang Mingxi winked at Lu Jintang and said to Lu Qin half-jokingly.

Hearing this, the stone in Lu Qin's heart finally fell to the ground.

The smile on his face became even wider, and he quickly bowed and said, "It is such an honor to receive such praise from you!"

Yang Mingxi shook her head slightly and jokingly said, "Oh my, stop with all those sour, scholarly, and pretentious things. It's not like you at all."

Upon hearing this, Lu Qin couldn't help but burst into laughter, his voice hearty and bold: "Hahaha, Madam Lu, you are speaking frankly and righteously! To be honest, I really didn't go to school much!"

The laughter echoed in the air, as if bringing the two closer together.

Yang Mingxi suddenly remembered something and asked curiously, "Lu Qin, how old were you when you were first imprisoned?"

She knew that Lu Qin was about the same age as her, but hearing that he had been imprisoned for a full ten years was truly heartbreaking.

Lu Qin was silent for a moment, then, gazing out at the turbulent sea in the distance, he muttered to himself, "Well, eight or nine, I can't remember exactly... Time flies, and I'm almost reaching adulthood!"

Lu Qin's words revealed a hint of emotion and helplessness.

Yang Mingxi smiled and said, "You are truly amazing, then? Did you develop all these skills on your own?"

"No, no, it's just my wild imagination. It can't even be called an exploration because I don't have the materials to practice on." Lu Qin said regretfully.

"It doesn't matter. Now you have a chance. Just tell me what you want and I'll do my best to satisfy you." Yang Mingxi waved her hand and said proudly.

"Thank you, Madam Lu. I will naturally not be polite with you! Haha." Lu Qin said to Yang Mingxi with a smile on his face.

Yang Mingxi nodded slightly, then continued, "Don't be so formal. We're all here for this shipbuilding matter. I wonder if you've encountered any difficulties over there?"

After saying that, she raised her hand and pointed at the boat that looked almost finished.

Lu Qin looked in the direction Yang Mingxi pointed, his eyes fell on the small boat, and he slowly responded, "Madam Lu, you really hit the nail on the head. In fact, I have thought about the appearance of this ship countless times in my mind before, but every time I imagined it, it always felt a little vague. However, when I saw the drawing you provided, its overall shape appeared clearly in my mind in an instant, so this aspect is not too difficult." After speaking, Lu Qin turned his gaze back to Yang Mingxi, a hint of admiration in his eyes.

Hearing this, Yang Mingxi couldn't help but sigh, "It's true that an expert can tell the difference with just one look! What the ancients said is true."

Lu Qin shook his head and continued solemnly, "That being said, there's still a key issue bothering me right now, and that's the ship's power system. If we really want to achieve a net weight of 1,000 tons, then its power system must be powerful enough. Otherwise, wouldn't its other advantages be wasted? I've been thinking hard about this for a long time..."

"Power system? This is a really tricky problem! What do you think about it?" Yang Mingxi looked at Lu Qin with difficulty. She didn't know much about this field, so she could only throw the problem back to the other party.

Lu Qin nodded thoughtfully, gesturing with his hands as he explained, "I think an artificial power system is essential. We can consider using gears to achieve power conversion and control. By cleverly designing the proportional relationship between the gears, we can convert smaller forces into larger power outputs."

Hearing this, Yang Mingxi frowned slightly and thought for a moment before saying, "Hmm...but I think that while gear transmission is feasible, it may require higher precision and strength for the gears themselves. In comparison, perhaps a wheel-axle transmission would be more suitable?"

Lu Qin was stunned at first, then reacted and stroked his chin as he analyzed, "Axle drive? If you want to ensure its durability, you must use metal to make the axle. But if you do that, the heat generated by friction will probably be unbearable."

Yang Mingxi smiled and said confidently, "That's right, the axle must be made of metal. But as for the transmission belt, you can use materials like leather. And you can soak the belt in oil for a while beforehand to allow it to fully absorb the grease, thereby reducing friction with the axle and the resulting heat."

After saying this, a glimmer of confidence flashed in Yang Mingxi's eyes.

"Wow! This is a great idea! When the belt is soaked in oil, the friction on its surface is significantly reduced, and at the same time, its firmness is greatly increased! In this way, we can try to apply this method in practice!" Lu Qin's face was full of excitement and he couldn't help but blurt out.

"Yeah, that's right! But it should be noted that this is currently just an active power system. If we can cleverly use some external forces, such as wind power, etc. on this basis, wouldn't the entire device become more perfect? It's a pity..." When Yang Mingxi said this, he suddenly paused, as if he couldn't remember the specific working principle of the sail.

"Oh, it's actually very simple! Isn't it just about harnessing the power of the wind? Didn't we already carefully design the sail? As long as we use it properly, I'm sure we can achieve the desired effect!"

Although Yang Mingxi's presentation of the relevant knowledge was not very professional, fortunately Lu Qin quickly understood the meaning of his words.

"Yes, that's what I mean! Do you think this will work? We can also use the seawater brought up by the boat as it moves forward, just like the principle of a waterwheel."
