The field inspection is to create a topographic map of the lake bottom. Because the fence needs to sink to the bottom of the lake, it requires a flat terrain as much as possible.

Wang Bo can also use a sand table to solve this problem. The sand table is a 3D terrain map, but he must do it so that others can know how his terrain map came about.

Raymond discovered the business opportunity again and said with a smile that he wanted to introduce him to the dive surveyor. Wang Bo shrugged and said, "This is not necessary. You provide rental for diving suits here, right? OK, rent a set for me, I will do this job."

After hearing his words, Raymond was a little confused: "My friend, it's autumn now. Are you sure you want to go into the water by yourself? As far as I know, you are a Monopoly. It doesn't cost much to detect the terrain at the bottom of the lake. You don't need to go into the water by yourself, right?"

This is not a matter of how much money, but Wang Bo feels that he cannot spend money in places where there is no need to spend money. He can use a simpler way to determine the terrain of the lake, so why should he spend money to be the sucker?

He refused Raymond firmly and rented a set of cold-proof diving suits himself.

Raymond didn't ask for rent, after all, this is a big customer. He bought so much fishing gear from him, which should give him some benefits.

Moreover, he wanted to fish for big fish on a long line. As a veteran in freshwater fishery, he knew the area of ​​Haweiya Lake and knew how much more things needed to be purchased in the later stage of building a natural fishery. He wanted to win over this big customer. In the future, he could make money and become rich just by relying on Wang Bo's freshwater fishery.

Back in the town, Wang Bo went directly to Haweiya Lake, picked up his diving suit and prepared to go into the water.

Bo's mother said worriedly: "We don't know how deep this lake is. Can you go into the water by yourself? Otherwise, let your father go down, you haven't been in the water after graduating from college, right?"

Wang Bo is familiar with diving. He has grown up on the beach since he was a child, slapped the waves. To be honest, he can't catch fish, but he has done a lot of diving and touching sea shells under the sea.

However, after graduating from college, he left his hometown to work and did not dive much.

Fortunately, the lake is not as good as the ocean, there are no undercurrents, no tides, and no big fish. Although it can occasionally ripple a few waves, the ball wind is just that, and the waves are very small.

Wang Bo promised his mother a few words, and then signaled Eva and Raymond to help him wear his diving suit.

For the purpose of insulation, Raymond gave him a dry wetsuit. This suit is made of foam synthetic rubber, with special waterproof zippers and other accessories that he cannot wear.

Raymond sorted out the dry diving inflatable exhaust device for him and asked, "You really have to go into the water by yourself? Otherwise, I'll go down, but honestly, my drawing ability is a bit poor, so I may not be able to make a good topographic map."

Wang Bo joked: "You have a little conscience, but you don't need to go into the water. Please help me organize the inflatable exhaust pipe."

Because air must be injected and discharged from the wetsuit to maintain neutral balance, the suit he wore had a pipeline, which was connected from the medium-pressure interface of the first level of the regulator to the inflatable port of the wetsuit. This pipeline is very important, and if there is a problem, people will be suffocated to death underwater.

After putting on his clothes, he adjusted his oxygen cylinder and tried his breathing, then gave him a thumbs up and said that there was no problem.

Eva shook the connection line in her hand, meaning that if he felt something was wrong, she would quickly release the signal, and then she would pull him up in the shortest time.

Wang Bo jumped into the water and entered his field of vision through the diving glasses.

This fish farm is located in the northwest of the lake, far away from the pasture. He chose this area because he found from the sand table that the bottom of the lake here is the flattest, and there are no aquatic plants, so it is more malleable.

There are many fish in the lake. Because of the heart of the lake, these fish are very active and swim happily in the water.

Wang Bo slowly sank in the water. Several brightly colored rainbow trout seemed very interested in him. He swam over without fear, and swam around curiously.

Seeing this, he reached out to caress the fish, but the rainbow trout was scared, and the small fish scattered and disappeared into the clear lake.

The breeding area is relatively shallow, with a depth of only more than ten meters, and it quickly fell into the water.

In this way, he didn't have to watch the terrain at the bottom of the water and swam freely in the water.

The dry diving suit has a good warmth effect. The good insulation layer separates the cold lake water outside. He can't feel the coldness and is very comfortable swimming in the water.

I haven't been swimming for a few years. At first, he swam a little slowly. After getting used to the resistance of the water, he began to swim faster.

Long and short aquatic plants grow at the bottom of the lake. They float up under the action of buoyancy and slowly shake with the water waves, which looks a bit scary. After all, the autumn sunshine is not strong and cannot penetrate more than ten meters of lake water. It looks very dark at the bottom of the lake with naked eyes.

After swimming for half an hour, the indicator light on his chest flashed. It was Eva sending him a signal to him to come up and take a break.

Wang Bo knew that Eva was worried that she would not be able to stand it when she suddenly went into the water. Although he was not tired, he still surfaced for rest.

This way, he wandered around the water for two and a half hours, and finally it became dark, and then he emerged from the water and took off his diving suit and ended the terrain exploration at the bottom of the lake.

In the evening, he finished his meal early and went into the study by himself, saying that he was drawing the topographic map according to the photos and memories he took. In fact, he just painted it at the bottom of the sand table lake.

The bottom of the lake is very flat. Wang Bo just drew a few strokes like a graffiti and then finished it. Then he opened the sand table to contact the wild horses.

Recently, he has been in contact with wild horses. At this time, the dark horse king has no resistance to the occasional feeling of touching his body. When Wang Bo caresses it from the air, it just looks left and right strangely, and then continues to lower his head and eat grass.

After observing the horses, he found that these horses had changed after they arrived at the stadium. The biggest change now lies in their mental state and fur color. They are more energetic and brighter in their hair. They are not as weak as they are covered in fur and listless as they first came.

In addition, their size has also changed. The horse king's black fur is dark and shiny, and the horse's hair on his neck has grown a little. When it runs, the horse's hair floats in the wind, which is extremely chic.

Also, its muscle lines have become much smoother and its body has become longer. Wang Bo has never seen any pure-blooded horses or sweat-blooded BMWs, but he thinks that the dark horse king is not much worse than those photos of famous horses on the Internet.
