After obtaining the drawings of the rammed earth city wall, Su Yu prepared to build the rammed earth city wall the next day.

The importance of rammed earth walls to the tribe is self-evident.

Although building the city wall in winter is a bit inconvenient, the benefits are also obvious. You have enough time and no one will disturb you.

Originally, Su Yu wanted to teach, but because of the rammed earth city wall, Su Yu had to move this job to the evening.

Su Yu handed over the construction technology of rammed earth city walls to Su Zhuang and the tribesmen with him, and asked them to be responsible for the project.

Rammed earth city walls are made of rammed earth, but they are not entirely made of earth. The middle of the wall needs to be filled with stones for reinforcement.

The construction of rammed earth city walls requires planning the general scope in advance to ensure that the entire tribal camp can be included.

We still need to leave space for expansion, but we don't need too much space now. We just need to be able to surround the tribal camp and leave some space. If we need to expand later, we can continue to build a city wall to form an inner and outer city.

Su Yu took a look and decided to build a city wall one kilometer long and wide. It is not necessary if it is too long. It will only increase the workload and prolong the construction time. Now the population of the tribe does not need too much space. Even if it is one kilometer long and wide

The city wall also took a long time to be built by the tribe.

Basically all members of the tribe were mobilized, and both men and women were required to participate in building the city wall. Only some tribesmen who had regular jobs were engaged in their own work. In order to speed up the construction, Su Yu also sent people to the Tanlang Camp to call people.

Build the wall together.

"Chief, do we need to trade with nearby tribes again?" Su Xun, who was working, suddenly asked.

"Of course you want to go. You can continue going tomorrow. If you encounter a hungry tribe, you can advertise that we are recruiting people to work here and provide food and accommodation. We have too few people and it is not enough to build a city wall," Su Yu said.

He found that the labor force of the tribe was still somewhat scarce, and the workload of building rammed earth walls was huge.

The current construction speed is very impressive. It took a whole morning to build only a dozen meters in length. The height of the city wall is less than 1.5 meters and the thickness is only two meters. This is still the speed of one head fighting. If it is divided into four heads, it will probably be

It's so slow that the construction may not be completed even after winter.

"I understand, patriarch."

There are many tribes who are short of food in winter. If the recruitment of workers includes food and accommodation, then many tribes will definitely come here with their families.

One day passed, and the construction work of the rammed earth city wall got off to a good start. The city wall was built to be more than thirty meters long, but the height was still only one and a half meters.

In the evening, Su Yu taught them, and also began to teach the four Bai Shuang sisters some knowledge related to their talents. As an Internet otaku, Su Yu had access to all kinds of knowledge on the Internet, and also watched a lot of short videos.

I know a little bit about everything, but I only know a little bit, but I don’t have a thorough knowledge.

Su Yu didn't expect to be able to teach them much. They had to rely on themselves for the rest, unless there were books related to these fields sold in the later mall or obtained from future victory rewards.

It was another ordinary day, and Su Yu fell into sleep.

In the early morning, Ji Ni and Su Xun set out, bringing salted fish and pottery. This time they did not bring white salt. Su Yu found that with salted fish, there was no need to sell salt. Anyway, there was no difference. For other tribes

To humans, this fish is not as important as salt.

I thought that the tribe had piled up a lot of salted fish. If they were not disposed of, they would not be able to eat them all.

Su Xun and the others left, and Su Yu continued to devote himself to the great cause of building the city wall.

…

Looking at the map, Su Xun and Ji Ni changed their direction. There was a high mountain called Yanshan in that direction. Naturally, there was a tribe named Yanshan there.

At this time, the Yanshan tribe was facing an immediate food crisis. They had run out of wild fruits. The heavy snowfall for a month prevented them from going out to hunt. After the heavy snowfall, all the animals in the forest hid and hibernated. They found

There are no traces of animals.

Seeing that food was getting less and less, they were helpless.

Today, they went out to look for food as usual, but now they didn't have much energy anymore.

"Chief, do you see something over there?" A member of the Yanshan tribe suddenly saw a black figure moving at the end of the white snow scene in the distance.

"Go over and have a look." The chief of the Yanshan tribe looked over there and saw a dark shadow moving. He immediately thought it was prey and ran over excitedly with his men.

When he got closer, he discovered that the black shadow was not prey, but a group of people, the size of which was comparable to his own.

There were many tall animals they didn't recognize beside them.

This group of people was Su Xun and his group. The people from the Yanshan tribe saw Su Xun and his party, and Su Xun also discovered them.

The two sides looked at each other, and finally the leader of the Yanshan tribe spoke.

"Where are you from?"

"We are a caravan from a large tribe in the east, coming all the way west to trade." Ji Ni stood up to talk to the leader of the Yanshan tribe.

"Caravan, here to trade?" The chief of the Yanshan tribe automatically filtered out the words he didn't understand, such as east and west, and obtained the most important words.

Looking at Ji Ni, the chief of the Yanshan tribe seemed to remember that he had seen this face before.

"Do you have food?" He didn't remember, he just didn't think about it and asked.

What they need most now is food, and nothing else can arouse his interest.

"Yes, we have a kind of food called salted fish. It is not only edible but also adds salt." Ji Ni introduced. Su Xun was studying on the side. He was somewhat interested in business.

"Show me." The chief of the Yanshan tribe's eyes lit up when he heard there was food.

Ji Ni asked someone to take out a salted fish and handed it to him.

"Is this the salted fish?" The chief of the Yanshan tribe held the salted fish. He felt that the salted fish was hard and there was a strong salty smell on his hands after touching it.

"How can I change this salted fish?" Since it is food, the chief of the Yanshan tribe will definitely not let it go. Since they will buy it, it should be edible.

"It depends on what you have." Ji Ni replied.

"What do we have?" The leader of the Yanshan tribe thought about what his tribe had.

"Go and take out the things from the tribe's treasure house." Suddenly, the leader of the Yanshan tribe thought of something and ordered his confidants next to him.

"Clan leader, do you really want to take the things from the treasure house?" his confidant asked uncertainly.

"You can take it if you want. Is there anything else in the tribe that can be exchanged for now? The things in the treasure house are just for storage. Why not take them out and use them." The chief of the Yanshan tribe explained.

"Yes, patriarch."

"Can you offer anything to trade?" Ji Ni asked again.

"Right away, I'll have someone go get it now."

"Okay, let's wait." Since the business can be successful, there is no need to rush to the next stop.
