This made him think about making a saw, but he ultimately didn't say it aloud.

Lin Ying studied very hard during the fifteen days of training. Master Amu was truly amazing; she learned a lot from him. Just about saw teeth, she learned about different types of saws, such as the cutting edge and the longitudinal saw. She also learned the ingenious use of various falcon-shaped saws.

After learning these things, Lin Ying realized that what she had done before was really very rough.

Because of learning from Master Amu, Lin Ying learned more quick and convenient usage skills.

Therefore, from the bottom of her heart, Lin Ying regarded Master Amu as her mentor.

“Master, I’m leaving now. Take good care of yourself here, and don’t be so stubborn. I’ll come back to see you.”

Master Amu, puffing on the welding fumes, waved his hand and said, "What are you looking at me for? I've passed on everything I know to you, there's nothing more to teach you. If there's anything you don't understand, I won't help you."

Lin Ying shook her head: "Lin Ying chuckled, 'You've handed over your family's treasures to me, so you're my master! From now on, I'll take care of you in your old age!'"

Master Amu paused for a moment, then pretended nothing had happened: "I'll rely on you to support me in my old age. I won't have to worry about food or drink here. Just take care of yourself."

Lin Ying wasn't in a hurry to prove anything; she simply waved and left.

Zhang Shanlin picked her up again, but this time he didn't come in a military off-road vehicle, but in a large truck.

Besides taking Lin Ying back, we also need to bring the dragon bone waterwheel that Lin Ying made.

Looking at the huge machine, Zhang Shanlin couldn't help but get excited: "The irrigation canal is already built. Once you bring this big machine back, we'll be able to water our plants freely."

Lin Ying was also worried about the fields and couldn't help but ask, "How's the medicinal herb field doing now? What's the germination rate?"

Zhang Shanlin reassured him: "We planted everything according to your instructions, there's no problem."

Lin Ying was satisfied: "That's great."

Zhang Shanlin and Lin Ying didn't go anywhere else; they drove directly to the medicinal herb field.

When everyone saw that it was Lin Ying who had returned, they were all happy and looked over.

"Sister-in-law, who is that person? Is he the captain you were talking about?"

"Yes, Qiuyue, you're new here and don't know much yet, but our squad leader is quite capable. You'll find out as time goes on."

Qiu Yue smiled but didn't say anything.

But in her heart, she felt a little disdainful. How could someone who graduated from vocational school, joined the army, and was now training at the grassroots level possibly look down on a military wife?

I really don't know if Minister Zhang has something wrong with his eyes. Letting a military wife be the captain and lead them is simply turning the world upside down.

At Zhang Shanlin's call, everyone went over and helped carry the dragon bone waterwheel to the riverbank.

After Lin Ying adjusted herself for a moment, she walked to the side and started cranking the handle next to her. Soon, water was brought up in streams.

At this height, the water brought up flows directly into the irrigation canal.

Everyone was overjoyed to see Shui enter the water.

Unexpectedly, a cold voice from the side said, "It's just a waterwheel, why are you so happy? This waterwheel was invented eight hundred years ago."

Everyone's expression froze. Lin Ying couldn't help but glance at the person who spoke. However, she had things to do and didn't have time to care about these things. She just called to the person in front of her: "Minister Zhang, come here and shake the handle."

Minister Zhang glanced at Qiu Yue and sighed inwardly. This woman came from above, and he dared not offend her. He could only pray that she wouldn't cause trouble.

"Okay, is that alright?"

Lin Ying nodded, "Yes!"

Seeing Minister Zhang shaking the handle, Lin Ying went over and set up the water cart on the irrigation canal.

"Pfft, isn't this redundant? The dragon bone waterwheel doesn't have this. It's just gilding the lily."

Lin Ying glanced at the woman before continuing with her work. Zhang Shanlin, standing nearby, had been thinking how easy it was to shake the water like that; the water was brought up so easily.

Now, after hearing what Qiuyue said, he finally couldn't help but say, "Comrade Qiuyue, just do your job well."

Qiuyue pursed her lips and didn't say anything more.

Meanwhile, after the waterwheel was set up, the water flowing up would first hit the waterwheel, making it turn. At the same time, the water remaining in the canal would also drive the waterwheel to turn.

After the waterwheel started turning, Qiuyue couldn't help but say again, "This waterwheel of yours is completely useless. What's the point of having it? It's just..."

Before Qiuyue could finish speaking, Lin Ying took out another rope, first putting one end of it on the dragon bone waterwheel, and then putting the other end on the waterwheel above the canal.

The next second, Zhang Shanlin found that the handle in his hand started to turn on its own without him having to exert any force.

He slowly released his hand, his eyes widening in surprise: "They can actually send water up directly without anyone's help? Great, this is a really good idea, as expected of Comrade Lin Ying."
