After a grand ritual, the snake tribe returned to its daily routine.

The hunting team went out to hunt every other day, and the fishing team only spent the morning fishing, and the rest of the time, most of the labor force of the snake tribe had to go to the small river to dig and make bricks.

The brick-making and wall building is the first project of the snake tribe this year, mainly on the basis of the current wall of the snake tribe, and the height of the wall is continued to be increased with adobe bricks, so that the beasts on the ground cannot jump over the wall.

Su Yan predicts that the height of the final wall will reach more than 2.5 meters, and now the height of the wall is only 1.7 meters, and it is necessary to increase the wall by 0.8 meters, and at least 30,000 adobe bricks will be needed to complete the whole project.

Last year, it took the Snake Tribe a summer and half a spring to produce more than 80,000 adobe bricks to build a wall with a two-meter base.

The amount of work in this year's wall enhancement project is at least half less than last year's, and the tribesmen are already proficient in making bricks and building walls, and it is expected that the entire wall enhancement project will be completed before the spring is over.

In addition, Su Yan has another plan.

Because of its proximity to the trees, some tree-climbing beasts were able to jump over the walls.

Su Yan planned to wait until the completion of the wall increase project and when the rainy season came, find a cloudy day, and then set a fire in the woods outside the wall, and burn part of the woods outside the wall, it is best to burn all the woods from the snake tribe to the river, so that the clansmen can go to the river more assured, and they can see the danger from a distance and avoid it in advance.

After burning some of the woods, the rain will extinguish the fire, so that the fire will not spread, and the snake tribe will have a large open space to use.

These newly added open spaces allow the Serpent Tribe's living space to be planted in the open space if they can accidentally find some crops.

The matter of setting fire to the forest will have to wait until the rainy season comes, if there is less direct fire now, if there is no heavy rain for a long time, then the forest centered on the residence of the snake tribe will be destroyed, and it will be very difficult for the hunting team of the snake tribe to find prey, and maybe other tribes will be engulfed by the fire.

The clansmen are already skilled in making bricks to build walls, and there is no need for Su Yan to supervise the wall elevation project.

On weekdays, in addition to practicing martial arts and teaching two groups of students to learn writing and Mandarin, Su Yan also set his sights on making pottery.

Last year, Su Yan tried to make pottery for the first time, but it failed, and all the pottery embryos were shattered in the flames, leaving behind a slightly shiny pottery fragment on the surface, which became a treasure for children.

The Xiaohua Xiaoyue sisters have Su Yan as a backer, and they are the ones with the most pottery fragments in the hands of children.

In fact, there are also adults who like pottery shards, but they are embarrassed to grab them with children, so they can only watch the children compete and share pottery shards, and sometimes they will show envy.

Because when trying to make pottery, Su Yan thought of making bricks to build walls, and compared with the two, the importance of making bricks and building walls is greater than that of pottery, so he temporarily gave up making pottery and turned to making bricks to build walls, but Su Yan never gave up making pottery in his heart, and has been sketching out how to make pottery in his heart.

With the first failed pottery production, Su Yan accumulated a certain amount of experience, and after careful consideration, the second pottery production is about to begin.

The first time the pottery was made, the pottery was relatively thin and uneven, and the made pottery embryos were directly placed in the fire to be fired, and the flame temperature was not easy to control, which eventually led to the fragmentation of all the pottery embryos.

This time Su Yan plans to make a pottery kiln with adobe bricks first, and put the finished pottery embryos into the pottery kiln to fire, which can control the temperature more easily than a fire and increase the success rate of the finished pottery.

In addition, the pottery embryo made this time is not as thin as the first time, but is very thick and large, and it looks rough and ugly.

However, such coarse pottery embryos have a much higher success rate than the first pottery embryo when firing, and they are less likely to break.

Both improvements can increase the chance of success to a certain extent, and Su Yan mobilized several adult clansmen to start a second attempt at making pottery.

First of all, a pottery kiln was built with adobe bricks near the south brick wall, this pottery kiln is the simplest vertical pottery kiln, the main body is a hollow kiln chamber inside, almost a quarter of a sphere, the bottom diameter is about one meter five, the height is about one meter, the part of the plane leaves half of the area as an opening, and after putting the pottery embryo into the kiln room, the opening is sealed with adobe bricks.

There is also a place for burning fire at the bottom of the kiln chamber, and the flame enters the kiln chamber through the hole under the kiln chamber, and the pottery embryos in the kiln chamber are roasted.

It took about four days for Su Yan to take three people (all women) to build the pottery kiln he needed.

Then Su Yan began to make pottery embryos.

Choose the most delicate clay, and you don't need the first time that the back is a little convex slate, just choose a wide slate that is relatively flat on both sides, square it on the ground, and then pour the adjusted clay on the slate, and make the bottom of the pottery first.

When making the first pottery, Su Yan did it himself, and the three clansmen were watching carefully from the side, and they also had to do some auxiliary work.

Soon, a round pottery embryo with a diameter of about half a meter and a thickness of about two centimeters appeared.

After that, Su Yan took a ball of clay, kneaded it into strips of clay with a diameter of about two centimeters, and then coiled upwards along the edge of the bottom of the pottery embryo until the edge of the mouth, and finally smoothed the inside and outside of the pottery embryo with stone chips.

Finally, a cylindrical pottery with a diameter of about half a meter at the bottom and a height of about 40 centimeters was made and placed in a cave to dry.

This finished pottery embryo looks very thick, and it is also very thick and ugly, which is completely inconsistent with Su Yan's aesthetic concept, but in order to fire the pottery that can be used, Su Yan can only make ugly pottery embryos that can increase the probability of success.

After placing the pottery embryo in the cave, Wu also went to look around the pottery embryo a few times.

Wu could roughly guess some of the uses of this thing from the shape of the pottery embryo, and Su Yan directly told Wu Dao: "This thing needs to be roasted with fire before it can be completed, and it can be used to fill water." ”

Wu was surprised when he heard Su Yan's explanation, and guessed that this thing was a technique taught by the gods to the gods, and the gods really favored the tribe.

Su Yan returned to the outside of the cave to make pottery embryos, and this time, Su Yan asked the three clansmen to participate more in the production of pottery embryos, knowing that the three of them could make pottery embryos alone.
