Shortly after Shao Xuan returned home, Lang Ga came to inform him of the patrol. Each hunting team had a place to be responsible, and three groups of people took turns to guard it.

Participating in defense does not necessarily mean that you will encounter dangerous things, it just plays a preventive role. After all, there are too many unknown factors in this river, so it is always good to be prepared.

"Tonight Mai and the others are going to start patroling. You can go with me to change them tomorrow morning." Langga said.

"Okay, I understand, what do you need to bring?" Shao Xuan asked.

"Don't bring too many stone tools, just weigh your hands, it's only half a day each time." Langga pointed to a place at the foot of the mountain, "It's right there, by the river, not far from where you used to fish."

"You may not know that you stayed in the cave last year. After the rainy season comes, the river surface will rise a lot, probably... there." Lang Ga pointed it to Shao Xuan.

There, there was a line surrounded by stones, and there was no house there where the stone line went down.

Therefore, the people living at the bottom of the tribe are only near the foot of the mountain, but they do not build houses directly at the foot of the mountain, which is because of the rising water in the rainy season. The people who used to temporarily stayed near the river for fishing have now all evacuated. Before the rainy season ends, they will no longer approach the river.

Thinking that Shao Xuan might not know what would happen in the rainy season, Lang Ga even told Shao Xuan something that had happened in previous years. When the rain was getting lighter outside, Lang Ga took Shao Xuan over and took Shao Xuan around, and confirmed that it also made Shao Xuan mentally prepare. Although the place they were guarding would not be very difficult, they still need to pay more attention.

"In other words, the hunting team will not leave to hunt until the end of the rainy season?" Shao Xuan asked.

He had thought he had just stayed in the tribe for a while and would go hunting if there was no trouble. But when Langga said, this means that he had to stay in the tribe throughout the rainy season? What would people who lack food eat?!

"There is nothing to do about this. The tribe is like this. For example, many people on the mountain stock up on a large amount of goods and the prey level is also high. If you can survive, the people at the foot of the mountain will be in trouble. Even if you stock up on some, the level of the beast meat is not high and the energy provided is limited. Most of the time you will still be hungry, but!" Lang Ga smiled and said, "This is much better than winter, because during the rainy season, some things will come out and we can pick them up and eat them."

"Things?" Shao Xuan frowned when he thought of the various insects coming out of the training ground. If he really had nothing to eat, he would have to use them to do it.

"You will know then." Langga also said too much, "I can't starve to death anyway."

Um?

Shao Xuan was really curious now. Listening to Lang Ga’s words, it was not the kind of bug that emerged from training, but something else?

"It's just like this once a year. Although it may be dangerous, be careful. It's okay, don't worry." Lang Ga clenched his fists and beat Shao Xuan's shoulder to show encouragement.

Shao Xuan rubbed his shoulders and looked at the river surface in the rain.

The overlords in the river appear from time to time on the distant river surface. After observing the terrifying river beasts, Shao Xuan had a doubt. The overlords in the river seemed to be heading in one direction, which can be seen from their jumping movements. It would be easy to say if it were some situations, but all the terrifying river beasts exposed over the water surface were headed in one direction, without exception!

"Is that upstream or downstream of the river?" Shao Xuan pointed to the direction of the river beast when it jumped up and asked Lang Ga.

"Upstream and downstream? I don't know, I haven't been there, it's too far." Langga said indifferently. For him, there is no difference between the upper and lower streams of the river and it will not be too much.

Shao Xuan looked at that direction and thought about what was there, and why did the overlords in the river head over there. The river was already big enough. If it weren't for the river water, at first glance, he would have thought it was the sea... the sea?!

Could it be a river entering the sea?!

Shao Xuan recalled the situation of following the hunting team twice, speculated the location and terrain, and came up with a summary. The current orientation of the overlords in the river is mostly the lower reaches of this big river. If this river really enters the sea, then why should the overlords in the river swim towards the sea during the rainy season?

Many fish will cause periodic directional back and forth swimming due to reproduction, food, or overwintering, etc., which is the so-called migration characteristics. So, are the overlords in these rivers also engaged in similar migration behaviors?

Shao Xuan shook his head, everything was just speculation. He asked Lang Ga and the others that he would not come to the result, because they had no idea what the sea was.

Regardless of whether the overlords in the river are swimming in the rainy season, there is nothing for Shao Xuan now. However, after returning later, Shao Xuan will record the observed phenomena in his "laptop".

Shao Xuan had long cleaned up some animal skins suitable for recording, which were used to record things, including those paintings I saw in the cave before, which Shao Xuan also drew based on his memory. If the animal skins could not be preserved for too long, they would be replicated into stone slabs.

His eyes moved back from the giant beasts in the distance who could not see clearly. After staying on the river beach for a while, Shao Xuan suddenly said, "Langga, do you think you can make a few fish fences here?"

Lang Ga, who was thinking about how much food he could get this rainy season, was pulled back to his senses by Shao Xuan's words, and asked in confusion: "Fish Gate? What is that?"

"It is a kind of thing to intercept fish made of wooden sticks and nets." Shao Xuan described it roughly, and then continued: "I thought, let's see if I could use such a fish fence as a simple trap."

"Train?" Lang Ga's eyes lit up.

"Actually, it's a very simple thing..." Shao Xuan took out the stone knife he carried with him and drew on the ground.

As Lang Ga, who also uses trap set skills, once you see what Shao Xuan said and then contact the drawings on the ground, you can infer Shao Xuan’s meaning.

He was afraid and slapped his head, Lang Ga regretted, "Why didn't I expect it before?"

What Shao Xuan wanted to do was a simple fish-style trap, which was not difficult and did not require other more precise settings. It was just like setting up a fish-style grid, using wood or stone pillars to make a fence and fence, and the fish-style grid was rolled inward like a mosquito coil. However, some were rolled inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward inward in the form of a round, while others were rolled inward inward inward in the form of square. Shao Xuan wanted to see the differences between these types of traps. The only opening of this simple fish-style trap was towards the direction of the river.

Or use a fish grille to make a bag shape, such as the larger letter omega "Ω", which is different from the former, with an opening facing away from the river. In this way, after the tide is low, the fish swimming in will be trapped inside.

Unless the fish swimming in has a high IQ, it is generally still more trapped. Shao Xuan tried it in his previous life.

However, because Shao Xuan had not participated in the tribe's rainy season patrol, I wonder if this setting could be added at this time, so I asked Lang Ga.

"Yes! No problem at all!" Lang Ga looked at the river surface that had not yet begun to rise sharply and called Shao Xuan: "Let's go find the stone quickly and set up this set before the river surface has risen!"

Because some things in the river eat wood, if you set up a fish fence, you can’t use wood, you can only use stones. However, when you don’t pay attention to the stone, it is relatively easy to make the stone pillars used to make fish fences.

So, when Mai brought the first group of people to patrol, he saw Shao Xuan and Lang Ga who were busy on the river bank. From the place close to the river surface to the stone line set by the tribe, there was a fish fence at a certain distance.
