The bear-sickle, who had gone out, soon returned with his people, each of whom was carrying a packed bag of animal skins, and it seemed that they had made a good harvest.

"Have you disposed of everything, is there anything missing?" Shen Nong asked.

"Well, I watched the clansmen throw all the bodies of those Tushan people into Bai Ze, there was blood stained in that place before, and I have turned all of them, and I will never be discovered by others. Xiong said with an oath.

"Very well, then go and hide all this salt now, hide it a little more secretly. Shen Nong said.

The bear sickle nodded, and took a step towards the Great Cavern, which seemed to be intent on hiding the salt inside.

When Shen Nong saw this scene, he hurriedly shouted Xiong Sickle in a hurry: "Eh, where are you going to hide the salt?"

"Put it in the cave where we live. Xiong replied bluntly.

"Eh, you are not afraid of being discovered by others in the cave, if someone goes in to search, won't they find this salt immediately?" Shen Nong waved his hand and said, "Don't hide there, is there any other place in our tribe where you can hide things?"

Xiong Yao thought for a moment and said, "There is no other place except the cave where we live and the cave where you live. ”

"Alas. Shen Nong sighed, worthy of being a human living in a primitive era, he had no awareness of building a storage room at all, let alone storage buildings such as warehouses and cellars.

At present, more than a dozen bags of animal skin square bags are like more than a dozen time bombs for the Huangqiu tribe, if the people of the Tushan tribe find out, it will directly cause conflicts and disputes between the two tribes, so what Shen Nong must do at present is to store these dozen bags of animal skin square bags in a hidden way.

As long as the entrance to the cellar is covered with wooden planks and mud, outsiders will not be able to find the location of the cellar unless it is guided by the tribesmen of the Huangqiu tribe.

Just do it, this is the habit that Shen Nong has developed in the Huangqiu tribe in the past few days, anyway, he is the witch of this tribe, and basically no one dares to refuse his order, but will raise the strength of the whole clan to help.

"Xiong Yao, call a few more powerful clansmen to come over, and you can also call a few more clansmen to go to the forest to chop some wood for me to come back, the number is more, I will be of great use." Shen Nong said, and at the same time, he quickly recalled a picture of a solid wood structure cellar with a solid structure in his mind.

Once when Shen Nong was taking an architectural design class in college, he saw the tutor take out a very old-fashioned four-beam column-shaped cellar called the Fang Bone Style, the structure of this cellar is to pave a layer of wooden planks in a square concave soil pit, and at the same time, you have to make sure that the soil layer under the wooden plank is hard and hard by you, and there will be hidden dangers such as foundation subsidence when heavy objects are pressed on it.

Next, you cut out a square the size of a basketball in the four corners of the pit, and take the corresponding shape of a sturdy wooden pillar and insert it vertically to serve as the beam of the cellar.

The third step is to put four long strips of wooden planks in the form of A and B shop, B and C shop, C and D shop, D and A shop, on top of the four beams and columns to form a hollow shape, at this time you can lay the wooden planks on this hollow shape composed of four wooden boards, and close the whole cellar roof, and on the other hand, the four wooden beams and columns will resist this 'ceiling' composed of multiple wooden planks, thus forming a stable underground space.

Finally, you put the earth on the plank, cover it tightly, and dig a slope ramp from the adjacent land to connect the underground space you have laid out, and the cellar is built.

Xiong Yao's efficiency was very fast, and after a while, five male clansmen ran to Shen Nong's side, waiting for his command.

And Shen Nong didn't waste any time, and directly asked them to start digging up the soil two or three steps after entering the big cave, because Beibang and Pan had not yet made the relationship between shovels, pickaxes, hoes, and other civil engineering tools, and these five clansmen could only use the most primitive method, that is, squatting on the ground with their bare hands to dig the soil.

But after digging for a long time, because Shen Nong really couldn't stand their slow digging speed, he found five bones of unknown beasts in the big cave and threw them and said, "Take this and dig it, you put this bone into the soil, and then lift the other end hard, and the clods of soil will be turned over by the bones." ”

The soil in the big cave has long been hard because it has been trampled by the Huangqiu tribesmen who live here all the year round, and it is extremely difficult to dig.

So Shen Nong found them some flat, wide and long bone fragments, which are very similar to the shovel heads of modern shovels, and the digging principle between the two is the same, inserting one end of the bone fragments diagonally into the soil, and then pressing the other end, you can easily pry up the soil that has been solidified, which is easy to excavate.

With the help of bone fragments, the five tribesmen quickly dug open all the hard layers of soil on the surface, exposing the soft soil beneath the earth.

Shen Nong took a stone spear and drew a square of about 8m x 8m in this area, and said: "Dig according to this, the soil in these four lines will be hollowed out for me, dig a concave soil pit out, the depth is as long as two stone spears are so long, remember, the four walls of the pit must be flat." ”

The five clansmen nodded in understanding and began to work.

In this era when there are no excavation tools, it is very difficult to dig out an 8x8m deep pit required by Shen Nong, and it is impossible for these five people to dig out the specifications that Shen Nong wants without spending a while, so Shen Nong did not urge them, but walked out of the big cave to see how the people who went out to cut wood were done.

A total of four beams and columns and a number of long wooden planks were needed to make a cellar, because the cutting tools of this era were very scarce, and the stone knife was already considered the top tool, and Shen Nong did not expect the people who went out to process the wood into perfect strips, as long as there was not too much deviation in the shape.

In a short time, one by one, the clansmen came out of the forest carrying logs that had been chopped clean and leafy, and they were all about a man high, with pure white cores, brown bark, and a lot of early morning dew.

"Wu, the wood has been cut back, what should I do next?" one of the clansmen who was in charge of cutting the wood asked Shen Nong with a smile.

"Take a stone knife and chop these pieces of wood into planks, you know? The kind of pieces that are flat to the touch. Shen Nong asked tentatively.

"Oh, I'll try it then, I haven't done this before. The man nodded blankly.

Under the guidance of Shen Nong's hands and feet, all the idle clansmen came over with bone knives and stone knives to help him cut wood.

Although it did not reach the level that Shen Nong imagined, in view of the restrictions of the times, it was better than nothing.
