As Kong Ming appeared in the fertile field, the old farmer who was smoking dry tobacco naturally saw him, but the old farmer did not pay attention to Kong Ming's body, but continued to frown and smoke dry tobacco, looking very distressed.

If nothing else, this old farmer should be the gatekeeper of this pass, after all, although he looks like a sad face, the aura exuded from his body is a genuine beginner Yuan Emperor!

Judging from the way he dressed, this old farmer was somewhat similar to the Shennongzi that Kong Ming had seen, but the appearance and temperament of the two were completely different, and it was difficult to judge whether there was any relationship between him and Shennongzi for a while.

Kong Ming naturally had no disrespect for this old farmer, so he stepped forward and bowed: "The seniors are invited! The juniors have broken through all the way to this point, and when they see the seniors showing a sad face, I don't know what the juniors can help?"

The old farmer glanced up at Kong Ming, sighed, and said, "Help? Are you the Sea Dragon King? Is there still a magical power of clouds and water? There are thousands of hectares of fertile land here, and early seedlings have been sown, but unfortunately the water source is insufficient, and it is a pity to see that everything is going to be ruined!"

Speaking of this, the old farmer took a few puffs of dry smoke, and as the smoke erupted, his whole face looked looming, and the wrinkles on his face were more like ravines like tree bark!

Kong Ming carefully looked around, and saw that thousands of hectares of fertile land were evenly scattered on a plain, if it weren't for the lack of water sources, this place would definitely be regarded as a treasure land of feng shui! However, since the old farmer in front of him could sow thousands of hectares of fertile land alone, why was he helpless against the water source?

Obviously. This level is used to test the passer, as long as the water problem can be solved. If you think you'll be able to pass this level, right?

At that moment, Kong Ming nodded to the old farmer and said, "Irrigate ten thousand hectares of fertile land." It's really not an easy task, I wonder if there is a water source near the road? Maybe the younger generation can really help the seniors!"

The old farmer sighed again and said: "Originally, there was also a water source here, you see, at the end of the left, there was originally a mountain peak, and there was a clear spring on the mountain, which flowed all year round, and only needed to introduce the mountain spring water into the canal at the edge of the field, so there was no need to worry about the water source." But the other day, the space here collapsed. The mountain peak on the left has sunk and turned into a valley, although the clear spring has not been destroyed, but the water can still flow backwards to the upper part of the mountain, and the water of the clear spring cannot be diverted to irrigate the farmland, and the thousands of hectares of fertile land here will eventually be wasted. Alas, could it be that the first name of my god cultivator is going to be ruined here?"

After hearing the old farmer, who claimed to be a god cultivator, explain the difficulties he encountered, Kong Ming had a plan in his heart, and felt that it was not difficult to solve this matter. At that moment, Kong Ming said to Shen Gengzi: "Senior." In fact, it is not impossible to make the spring flow backwards. I wonder if the seniors can move and go with the juniors to see the surrounding environment?"

Shen Gengzi let out a soft "huh" before nodding to Kong Ming. said: "Let's go and have a look, maybe you young man really has the ability to solve the problem, then it is the good fortune of this ten thousand acres of fertile land." ”

So Kong Ming and Shen Gengzi together. When I walked to the place where the mountain peak on the left was sinking, I saw a large crater dozens of meters deep. This pit covers an extremely large area. The size of the radius is by no means less than 10,000 hectares of fertile land, but it can be said to be formed by the subsidence of mountain peaks. It doesn't look like much.

Of course, at this time, Kong Ming would not be entangled with Shen Cultivator about these subtle matters, but looked at the clear spring in the middle of the deep pit.

The water surface of the spring looks extremely vast, comparable to a large lake, and the water level is about 30 meters above the deep pit, so it is not easy to get water up. However, when Kong Ming was cultivating in Longzhong in the past, he invented the waterwheel because of the problem of water source for cultivating terraces in the mountains, so how could he not solve the problem of diverting water from low to high places?

To solve the problem of water shortage, it is very simple, as long as one or several large waterwheels are built, and the spring water is pumped up and poured into the canal, there is no need to worry about thousands of acres of fertile land without water for irrigation.

In the deep pit, there is a dense forest next to the clear spring, and there are a lot of big trees in the forest that are tens of meters high, which can be used as materials for making large waterwheels, so Kong Ming smiled slightly, and said to the god cultivator: "Senior, it is not impossible to divert water and pour it dozens of meters high, at least you don't need to have the ability of the Sea Dragon King to travel clouds and spread water!"

As Kong Ming spoke, he jumped down the pit and went straight to the dense forest, where he easily cut down one big tree after another.

The brilliant golden yuan force condensed into the shape of a lightsaber in Kong Ming's hand, and then cut the big tree into various profiles, as easy as cutting tofu. After a while, Kong Ming gathered enough materials and began to assemble a large waterwheel by the water's edge.

In less than half an hour, a huge waterwheel with a height of more than 50 meters was erected next to the clear spring. Then with the flow of spring water, hit on the fan blades of the waterwheel, the large waterwheel immediately rotated, when the fan blades sunk into the water rose, the water tank on each fan blade was filled with clean water, and when the fan blades rose to the top and fell, the clean water in the water tank was injected into the water inlet, and then flowed directly into the canal that irrigated thousands of hectares of fertile land along the pipeline!

In this way, the large waterwheel can operate on its own without any human assistance, and continuously carry water into the canal. In this way, the so-called problem of water shortage in fertile land is naturally solved.

Of course, the water source needed for thousands of hectares of fertile land is by no means solved by a large waterwheel, but since this large waterwheel can really play a role, as long as you draw a few more gourds, I am afraid that it will not be able to meet the needs of thousands of hectares of fertile land?

Seeing that the waterwheel could automatically pump up the spring water, Shen Gengzi couldn't believe his eyes, and muttered to himself: "It's that simple? Can it really be that simple? With such a miraculous irrigation tool, countless wastelands lacking water sources can also be turned into fertile fields! This is an epoch-making weapon!!

Speaking of this, the sorrow on Shen Gengzi's face was swept away, and he politely saluted Kong Ming and said, "Little brother, you can make such a magical irrigation tool, and the poor people in the world who rely on farming and eating must thank you for your great kindness! The old man is even more happy to surrender, and this level is naturally considered to have passed you!" (To be continued......
