Sweet and salty prehistoric husband and wife

Perhaps because of the activities of saber-toothed tigers, in the second half of the cold season, no wild beasts appeared in the cave again. This is a very lucky thing, and the injured soldiers can rest at ease. Modern people are several times faster, and Mr. Hua Yu once again clearly realized the difference between primitive humans in this era.

The temperature of the sun rises, and the snow slowly melts within a week. Some of the snow water is evaporated, some is absorbed by the earth, and most of it becomes water and flows down to low-lying areas to enter streams.

The terrain here is quite suitable for human habitation, and the rapid melting of such a large area of ​​snow water has not caused floods.

Mr. Hua Yu's plan for the Huze tribe has been finalized. It will be built by the river. The depth of the river can be used as a moat.

The yellow soil here has a strong cohesive force and can be used as rammed earth.

The so-called rammed earth is compacted soil, compacted and mixed mud blocks with high density and few gaps, which can be used for housing construction and city walls.

Due to the insufficient number of people in Huze, young and middle-aged people had to go hunting to make a living. Therefore, in the early stage, Mr. Hua Yu focused on the city wall, and the rammed earth had to be wrapped with bluestone bricks.

The main raw material of bluestone bricks is clay. After the clay is mixed with water, it is extruded and shaped, then baked in a brick kiln to about 1000 degrees, and cooled with water to prevent the iron in the clay from being completely oxidized, so that it has better weather resistance and water resistance.

The hardness of blue bricks and red bricks is similar, but the cooling method after firing is different, while red bricks are naturally cooled, which is simpler.

That is because the production process of red bricks is relatively simpler, and the hardness of green bricks is higher, which is more suitable for building city walls with force.

In order to resist the invasion of large beasts, the city wall is imminent. Mr. Hua Yu focused on the city wall. The city wall made of rammed earth and blue bricks is indestructible. There are no hot weapons, except for entering through the city gate, which can resist all foreign enemies and beasts.

The people of Huze didn't know that they were going to build an extremely strong city with their own hands, and they were busy packing their bags. They could finally come out of the cave and return to the tribe.

Although the life in the cave is so comfortable, you can't be lazy for the sake of temporary comfort. The hoarded food is almost bottomed out, and if you don't go hunting and gathering, you will starve again.

It doesn't matter if they are hungry, but Master Hua is never allowed to be hungry.They quickly packed up their things. Although the snow hadn't completely melted, there was no problem for the return journey.

The packing was completed in half a day, and some things were left in the cave, which will become their secret base. The cave door is closed, and the cave is covered with big trees. Unless the three-layered trees are removed, otherwise they will never Discover the secrets here.

Due to the snow, the return journey was delayed a lot, but they also hurriedly returned to the tribe after sunset.

The tribe, still intact and unspoiled by wild beasts, put all their belongings back in the big warehouse, to be sorted tomorrow, and they returned to their lairs.

The snow on the outside of the nest had melted long ago, and it was dry and tidy under the influence of the sun and wind, but it still had a taste after being idle for a long time. They opened the curtains to let the air flow, and they could only fall asleep in the middle of the night.

Due to the insect repellent herbs placed in the nest in advance, some herbal smell is mixed in the nest, but there are no insects and ants at all.

The Huze people lamented Master Hua’s precautions. In the past, they could sleep wherever they came back. They had to clean up for a long time to get rid of the bugs, and they could drag their tired bodies to sleep the next night.
