Rising from his nap, Tinch returned from cutting a large pile of pine branches from the forest, and built a quadrangular shelf from the wood he had cut down earlier. The shelves are two meters long, one meter wide, and about one meter eight meters high, and are divided into two layers, the lower one is used for fire, and the upper one is used to hang meat ready for smoking, so the whole shelf must be very strong.

After setting up the shelf, Ding Qi trimmed the pile of pine branches neatly, and put them on both sides of the shelf from bottom to top in order face down, so that the whole shelf was airtight. After doing all this work, Ding Qi took out a hand-saw, placed a thick trunk with a peeled bowl mouth on the open ground, pulled out a line from an umbrella line, stuck one end on the edge of the wood, crossed the thin line with a piece of charcoal, straightened the thin line, and gently lifted it upward, and a clear ink line was drawn.

Using this simple ink line and hand saw, the trunk was sawn into five planks two centimeters thick, and then the planks were placed on top of the bacon rack, which looked relatively flat overall, but there were some gaps, and there was still half the plank.

In the same way, five planks are sawed out and put on them, and then some thin mud mixed with weeds can be plastered in the places where there are gaps.

After the bacon rack was officially erected, Ding Qi lit a fire on the first floor of the shelf, put some green pine branches, and soon the dense smoke gathered in the entire shelf, slowly penetrating outward, curling and wafting, so as not to seal the smoke inside. Otherwise, the outer layer of the smoked meat will turn black, making it difficult to swallow.

Some time ago, the prey caught was basically hung on the bonfire, and the smoke on the fire and the heat of the bonfire were used to slowly dry, and there was no special smoking.

After hanging the saber-toothed tiger's two hind legs on a shelf, Tinch moved on to another important job: skinning the lizard.

Skinning hard armor animals, Ding Qi is also the first time that the eldest girl has been on the sedan chair. However, with experience in skinning other animals, he quickly skinned the lizard to the ground.

Ding Qi thinks that the lizard skin that he peeled off is very strong, and the appearance is still full of bone scales, even the bamboo arrows shot by his longbow can be blocked, which shows how strong this lizard skin is.

After peeling off the lizard skin, Ding Qi sprinkled the plant ash accumulated in the corner on the inside of the leather armor, and then rubbed the alkaline plant ash on it, trying to let the ash and the oil and fat on the leather armor fuse, absorb the moisture inside, remove the odor, prevent the fur from rotting and deteriorating, and also facilitate further removal of these dirt on the leather armor.

After wiping every part of the inside of the leather armor, Ding Qi stretched the lizard skin with bamboo slices and placed it on the large stone to dry. When it is almost dry, it is put together with other furs, and after finding a special raw material for making hides, it is uniformly nitrated. So far, Ding Qi has not found the raw materials to make this raw material.

The simple operation above is only the first step in nitration, and more complex operations are required to get a cooked fur.

After processing the skin, Ding Qi used a straight knife and an axe to remove the lizard's internal organs, cut it into several large pieces, and hang them on a bacon rack for smoking.

The current life is very full and can even be said to be busy, all the work needs to be done by Ding Qi himself, and he is so busy that he can't touch the ground. In this matter, Ding Qi is very nostalgic for the division of work in modern society.

He only needs to work hard to earn money, and then use the money to buy some tools, materials and even knowledge needed for life, work and study, and he can save a lot of time to do other things, which is the benefit of the division of labor. But in the primitive society, at least for the time being, it still does not meet the requirements of the division of labor, he has only one person, and he can only do everything by himself.

Of course, in a broad sense, in fact, Ding Qi also has a division of labor in his current life, and the object is the cutie, who currently assumes a social function: vigilance. This ensures that Ding Qi does not have to worry about safety all the time while sleeping, which can be regarded as a reflection of the division of labor.

Tinch once attended a three-month training session after a mission, and one of the courses was on "Maslow's Hierarchy of Needs". In this theory, the needs of human survival are summarized into five aspects, namely: survival needs, safety needs, social needs, respect needs and self-realization needs, and there is a need for self-transcendence.

In terms of his current state and primitive age, Tinch is still at the lowest level of survival needs, and will remain at this stage for a long time, needing to ensure that he has a process of development or adaptation in terms of water, food, sleep, physical needs, or spiritual needs. This is the premise that his life can be guaranteed, and if his life is not guaranteed, all this is empty talk.

Therefore, on the basis of being able to obtain basic survival needs, Ding Qi needs to take into account his personal safety at the same time, that is, he must do a good job in the safety protection of his body and the safety protection of the living environment.

Physical protection requires the creation of some armor and protective gear and weapons to protect oneself, while the safety of the living environment requires the construction of strong houses, fences and even early warning measures.

Through the lizard's attack on the sheepfold this morning, Tinch decided that his camp was not safe enough and still needed more protection.

As Tintch weaves the second fish cage, he thinks about some of the things he should do next, and one of these things is a key word: lime. Lime has a wide range of functions, and can be used to make fur, make adhesives, make foundation materials, paint walls, disinfect, etc. Now that he eats more meat, Ding Qi can focus all his energy on finding limestone.

Looking at the fish cage in his hand, Ding Qi was very excited, he did better than the first one, and there was progress. Find a slower flow of the river and tie each of the two fish cages to a rope made of vines, put a larger stone and some lizard entrails in it, and throw them into the river until the net is collected tomorrow afternoon.

In the evening, Ding Qi specially roasted two large pieces of saber-toothed tiger meat, filled three bottles of cold white boil, and made ten bamboo arrows to supplement today's consumption during the day, and prepared the items and weapons that needed to be carried, Ding Qi closed the door and went to bed early.

The next day, after getting up early in the morning, Tinch fed himself and the cutie, threw enough fodder into the two sheep in the sheepfold, and walked to the mountain behind the house with his basket and weapon.

The route that found the saber-toothed tiger yesterday was already familiar to Ding Qi, and there was no limestone-like existence. Today he plans to look in the opposite direction from yesterday's, and he may find something good.

The weather was getting hotter and hotter, and the humidity in the air was gradually increasing, and Ding Qi, who had been walking along the mountain road for an hour, was sweating profusely. From time to time, he stopped to watch, and struck here and there with the axe in his hand, but never found a target.
