The completion of the production of the simple workshop gave Wang Tian and the tribe the opportunity to practice and valuable experience.

The most important thing is to give everyone a sense of accomplishment and self-confidence, including Wang Tian.

The people of the tribe are worried about food, and they have food at home, and they are not panicking. This is still the case more than 10,000 years later.

The quest for food in primitive times. Just like the attachment of later generations to the land. It's ingrained.

When you have food, you want to be safe. With security, more food is available.

Want to get enough food. You have to have enough manpower. Want to get enough people. The safety of the tribe must be guaranteed. Only tribes can reproduce safely from generation to generation. The population can increase. It is only when the population increases that the tribe grows. The ability of powerful tribes to obtain food speaks for itself.

Primitive man understood this simple truth. When they see the walls that the Son of Heaven said, the house can bring them a safe and more comfortable living environment. Naturally, I am sincerely happy that my worries have been dispelled.

Wang Tianyou is anxious, as the saying goes, the greater the power, the greater the responsibility.

The tribe has 138 mouths, and according to later research data, adults should consume three taels of meat, three taels of vegetables, and three taels of carbohydrates every day. 6 grams of salt.

In the primitive era, there was no salt yet, and all of them were big stomachs. It is conservatively estimated that each person gets half a pound of meat every day. One hundred and thirty-eight people will need seventy pounds of meat, and a month will cost two thousand pounds of meat.

In the next three and a half months, the pigs were slaughtered and fed with feed, and the weight of the slaughter was 180~200 catties. And such pigs have to consume 11 pigs a month.

Based on the price of 10 yuan a pound of pork, the food cost of the entire tribe is 21,000 yuan a month.

And that's not just about satisfying the needs. If you want the tribe to be happy, you have to double it.

In the primitive era when material scarcity was so scarce, 20,000 to 40,000 yuan of wealth was created every month. The pressure can be imagined.

In barbaric times, wealth is not just about how much you can get, but how much you can keep.

Wang Tian did not make bricks or build houses in later generations. I have never burned lime and I have never grown grain. One person is fed, and the whole family is not hungry.

Knowing the principles of the atomic bomb does not mean that you will make it.

At the beginning of the crossing, he only hoped to hold on to the existing of the tribe. Hold on to what you have in order to create more.

And now the success of the simple house has strengthened his own idea. All this is true, and that's enough.

More than 300 adobe bricks made today were brought into the factory. Pile them up against the fence wall. Previously made clay pot blanks and dung basket stone hoe tools were also put into the field.

After everyone cleaned their bodies, Wang Tian ordered someone to pick up a few loads of quicklime and slaked lime and send them back to the tribe

Quicklime is a good desiccant that can slow down the decay rate of tribal wild fruits and the mildew of dried fish and meat.

Hydrated lime Wang Tian is going to use it to paint the walls. Not only beautiful, but also can prevent and repel all kinds of small insects and sterilize and disinfect.

On the way back, the tribesmen looked back at the built factory from time to time. I feel like I have another home in my heart.

A place that can shelter from the wind and rain can be a home.

After Wang Tian, Heizi, Dashou and Liu Bei cleaned up the dust in the pottery kiln, they added enough firewood to the kiln and covered the air inlet of the pottery kiln with stones. He then returned to the cave.

The gathering team had returned, and the little Fu horse walked towards Wang Tian with a snort, stretching out his long horse face to rub against Wang Tian's face.

As a former work partner, he is a soldier, and Wang Tian, who was born, also takes good care of Mana, but he has neglected it in the past few days after the crossing.

Wang Tian found that after this cargo crossed, it seemed to have grown a lot of fat. It seems that during this time, it was very moist with green and pollution-free forage and various wild fruits in the primitive era.

Wang Tian led the little Fu Ma into the cave, and in the kitchen area on the left, the tribesmen were already preparing dinner. The main meat eaten for dinner was the entrails of the animal that the leader had hunted yesterday.

Wang Tian piled up all the quicklime he had brought back earlier and placed it in the innermost part of the cave.

In order to achieve a more delicate and smooth effect, hydrated lime used for wall painting needs to be soaked and stirred to separate the hydrated lime residue.

That is, two pools were built on the ground, one for mixing lime and the other for precipitating lime.

The hydrated lime is soaked in a mixing tank, and the light lime powder floats and dissolves in the water through continuous stirring.

The impurities in it, such as stones, will settle at the bottom because of their weight.

The two soaked pools are connected, after full stirring, open the connecting valves of the two mixing pools, take advantage of the height difference formed when the pools are built, introduce lime water into the second sedimentation tank, and let it stand for a day or two to get fine lime.

In the process of releasing water, it is necessary to stir constantly.

And next to the sedimentation tank in later generations, there will be a blower that continuously pumps/sends air to the bottom of the tank, which uses carbon dioxide in the air to accelerate the precipitation of lime.

In fact, if the requirements are not strict, you can only build a mixing tank, let it stand after stirring, and naturally separate two layers, and the lime residue that is taken away is actually silica, which is the main component of river sand. As an important building material, it is certainly not wasted.

The cave is not at all intended to be so delicately painted, just whitewashed.

What's more, there is not even a brush to paint the walls now.

It doesn't matter if you don't, just do it yourself. As a single dog or a man, you must have a certain amount of hands-on ability.

Wang Tian took out a handful of wild boars/hair, which was only possible last night when he specially asked the second brother to collect all the wild boars/hair.

Otherwise, with the original urine of the people in the tribe, the pork is grilled with hair. Of course, this is also because there are no metal axes yet.

Sort out the wild boar/fur and divide it into small handfuls and place them well.

Then let the second brother of King Kong use an axe to chop out several wooden planks of thirty by ten centimeters and a thickness of about two centimeters.

Wang Tian wants to make a few brushes to paint the wall, so that everyone can enjoy brushing together.

He took out the key he had brought with him when he crossed over, took out a cross key, and sharpened the pointed part of the file with the small file on the saber. As a nail, first make rows of small holes evenly in the wooden board.

Then fasten the key tightly to a stone and push it into the fire with the tip pointed upwards to heat it.

When it burns red, hook it out of the fire. Pick up the wooden board, aim the nail hole on it, and press down the hole in the soup with force.

There are more than 100 eyelets on the 30-centimeter wooden board, and just when Wang Tiantang was about to collapse, he finally made one.

Suddenly he seemed to remember something. A slap in the face.
