In the early morning, pottery was still being fired in the earth kiln.

"Thank you for your hard work." Su Yu went over to express his condolences. Through the ventilation window, Su Yu saw the orange-red flames and the burned red pottery inside.

"We don't have to work hard, patriarch, we like this job very much." Several teenagers saw Su Yu and heard Su Yu's condolences, and smiles immediately appeared on their faces.

After calling Su Dachuan and bringing a few people with backpacks on their backs, Su Yu took the fishing net to the tributary of the river flowing through the plain and followed the tributary upstream.

The water in the river is very deep, and Su Yu cannot control the fishing net in his hand, so he can only come to the tributary.

Su Yu used a branch to explore the depth of the river water, which was about two meters deep.

"Dachuan, let's find a shallower place." Su Yu still felt that the water was a bit deep and it was difficult to set the net.

Walking up the river, Su Yu saw a river beach with hard rocks at the bottom.

"Dachuan, here." Su Yu ran to the river bank and found a perfect place to lower his net.

This river channel is on a relatively flat river beach. The river channel is very narrow and the water depth is very low. Su Yu only reached his knees when he stood in the river channel. There are many fish swimming downstream from here.

"Come on, let's help together. Pull the four corners of the net. The bottom two corners have to be pulled to the bottom of the water." Although there were stones tied to the bottom two corners of the fishing net, Su Yu still asked someone to fix the bottom for safety.

.

"The fish has come in. Don't worry about the small fish. Don't let the big fish escape." Su Yu shouted.

"There are so many fish, chief, this fishing net is so useful!" Su Dachuan grabbed a fat fish that was trying to escape, waved his arm, and threw it to the shore. The tribesmen on the shore saw it and immediately threw the fish away.

Put it in the backpack.

"Draw the net!"

Following Su Yu's order, the four people worked together to pull the net forward.

"Bring it to the shore." Su Yu was also very excited when he saw the fish in the net.

Finally, the fish came up, but it moved a lot.

Of course, if there were a little more, Su Yu would still be worried that the fishing net would not be able to hold on.

"Congratulations on successfully fishing with a fishing net, unlocking fishery, and gaining 200 civilization points and 10 agricultural points." The system's voice sounded in his mind, but Su Yu ignored it for the time being and looked at the fish caught.

One net of fish filled five baskets. There were many kinds of fish. Su Yu only knew a few of them, and he didn't know the rest.

It's not even noon yet. It looks like there will be a bumper harvest today, Su Yu thought to himself.

Su Yu asked them to carry the fish back first and then call some people over.

The construction of the tribe's houses is almost completed, so a lot of manpower is available.

There are so many fish in the river, it would be wasted if not caught.

Net more fish, even if you can't eat them all, you can smoke them into smoked fish and save them as food for the winter.

Su Yu and the others didn't wait long before the tribesmen rushed over. Everyone was carrying a backpack, and more than twenty backpacks were placed on the ground. Su Yu was very busy.

After two more nets, Su Yu and the others were panting from exhaustion.

"Come on, you guys also come and learn how to fish. You'll take your turn later."

Four strong tribesmen took over the fishing work, while Su Yu guided them.

"Yes, that's it...then you can pull it up."

A net of fish came up, and they were quickly put into baskets and carried back to the tribe. When the tribesmen saw so much food, they suddenly became more motivated to work.

"You continue to work here, I will go back and deal with these fish."

There were a lot of fish shipped back, and Su Yu had to process them quickly, otherwise they would stink and rot in a few days.

Su Yu summoned the female tribesmen who were weaving backpacks and asked them to stop weaving backpacks.

"I need you to work together to handle these freshly caught fish, otherwise they will rot."

Su Yu picked up a sharp stone and showed them how to handle the fish. He first disembowelled the fish, then removed the internal organs, and then cleaned the fish blood with water.

"You can each do one step, for example, she cuts the fish open, you remove the fish's internal organs, and the other one cleans the fish blood."

Su Yu taught them the concept of the assembly line and divided them into three groups, with each group responsible for different steps.

This is very efficient, and the processed fish are put into clean baskets.

"Follow me." Su Yu called a few more people and asked them to collect branches and leaves.

At this season, there is basically no green vegetation in the tribal area. In order to emit a lot of smoke after lighting the branches and leaves and not burn out so quickly, Su Yu sprinkled some water on the leaves.

After setting up a support, Su Yu used a plant leaf similar to a palm leaf to hang the fish through the gills of the fish on the support. He hung more than a dozen fish at a time, then lit the soaked leaves underneath, and thick smoke billowed from the bottom.

The leaves emerged from the leaves and enveloped the fish.

Smoked fish mainly dries out the water from the fish so that it can be stored better and stored for a longer period of time.

Thick smoke floated into the air. If people from other tribes saw it, they might mistakenly think that the forest was on fire.

Near noon, Su Yu passed by the earth kiln. The earth kiln had turned off, and Su Tu and the others were observing the internal conditions of the earth kiln.

"Chief, the fire inside is gone, but it's still very hot inside."

"You can take it out when it's completely cold."

"Chief, can't the temperature be lowered by pouring water on it?" Su Tu asked doubtfully. In his opinion, if you want to lower the temperature, pouring water on it won't lower the temperature immediately.

"If you pour water on it, the pottery will not be able to withstand it and it will crack directly and expand with heat and shrink with cold... Oh, forget it, you don't understand this yet. You just need to remember that when firing pottery, you must wait for it to cool down, and you can't use water to cool it down.

."

Su Yu also wanted to explain the principle of thermal expansion and contraction, but when he thought about it carefully, it seemed that they didn't understand it even after explaining it. He couldn't finish explaining the principle of thermal expansion and contraction and then explain what air is, and then go on to the periodic table of elements. This

Thinking about Su Yu's head, he immediately gave up the idea of ​​explaining.

"Oh, okay, Patriarch, I will remember it." Su Tu nodded, as long as he remembered what the Patriarch said.

The lunch at noon was all fish, and everyone had a grilled fish. Everyone enjoyed the meal, except Su Yu.

Because he found that the fish was dry and had no taste at all, not even salt. Thinking about it carefully, Su Yu found that it seemed that he had not eaten any flavorful food for almost ten days.

Speaking of salt, it is an important necessity. Its role is not only seasoning, but also an essential nutrient for the human body.

"Su Xun, do you know what salt is?" Su Yu asked Su Xun who was happily eating fish.

"Ah? Patriarch. Salt? There is no salt around here. We all rely on drinking animal blood. If there was no salt, we might not have to go hunting." Su Yu stopped chewing and said.
