After more than an hour, the charcoal in the ash kiln burned out, and the temperature of the kiln slowly dropped. When I lifted the slab, I saw that it was filled with gray-white lumps, and there was no more limestone.

Ding Qi cleared a flat ground in the open space next to him, compacted it, removed the debris, and then took out the lime from the ash kiln, which was mixed with charcoal ash mixed with charcoal.

After all the clarification was cleared, the appearance of the lime in front of him made Ding Qi a little uncertain. In addition to those ashes, the lime that piles up together comes in three different colors: white, dark brown, and off-white. The white lime crumbles into powder at the touch, the dark brown has a glassy crust on the outside, and the off-white one is very hard, and if it can be broken by force, it is all in the form of flakes.

Ding Qi didn't understand why this happened, he only knew that limestone can be burned out of quicklime after high-temperature calcination, quicklime can be used for disinfection, and after adding water, it will become mature lime, and slaked lime can be used to build houses as a binder, paint walls, and make triad soil for foundations.

That's all there is to it, and nothing else is known.

Ding Qi can't figure it out, but he has a habit of not thinking about things that he can't figure out, and habits become natural. Anyway, this is also the first time I burn lime, and it is normal for there to be problems beyond common sense, and it must be that I have not grasped the know-how in the whole firing process, such as the selection of materials, temperature, and the location of fuel and limestone, etc., which may become factors for the failure of firing.

Looking at the small pile of quicklime, Tincch decided to mature them now. Dig a pit fifty or sixty centimeters long and wide, use a shovel to put quicklime into the pit, and gently pour water into it.

Burst! Burst! Burst!

As water is added to it, quicklime changes constantly, releasing a lot of heat and gas, which is why quicklime makes a popping sound. Ding Qi didn't dare to add a large amount of water to it in a short time, lest he react too much and waste this hard-won lime.

By the time all the water had been added, the whole pit was already boiling, bubbling, and hot steam was rising, bringing with it the characteristic smell of quicklime. When this state was gone, Ding Qi took a wooden stick and stirred it inside, so that they were fully fused, and quickly converted into mature lime, which could be used after most of the water had evaporated.

Now, all that's left is waiting.

Back at the wooden house, Ding Qi, who felt that there was nothing to do, saw a large pile of vines piled up in front of the house, and he had been so busy that he forgot to dispose of them. He took out a rope and tied up the large pile of vines, and took it to the side of the stream to soak in the water, and pressed a large stone on it to prevent it from being washed away by the water. This is a good way to deal with plant fibers, using microorganisms in the water for natural degradation, separating the fibers, and the rope made will be very strong. But this method has a drawback: it is slow and can take more than ten days.

But for Ding Qi, there is plenty of time, there is nothing urgent, but he doesn't want to waste it, he just wants to live every day to the fullest, do all the work well, and face this primitive society positively. He didn't want to be a cold bird, and he didn't do a good job of dealing with winter when it came, and was finally ruthlessly eliminated by nature.

With a whoosh, a gray shadow rushed in front of Ding Qi, who was thinking, startling him.

It's cute.

It circled around Ding Qi and rubbed its head against his calf, expressing its affection for Ding Qi as a daddy.

Recently, the baby lynx has grown very fast, and with an abundance of food, it has gained a lot of weight and size, and has grown to the size of a coyote seen some time ago, but it weighs more than twice as much. The slender limbs, wide soles of the feet, and thick flesh pads make it run like the wind, silent and fast.

Another thing that pleased him was that there were fewer and fewer lynxes, and the confidence and might of a jungle hunter were more and more reflected in it.

However, there is a bad phenomenon, there are fewer and fewer intimate performances like just now, and the personality is becoming more and more cold, just like a cat, not easily divulging his feelings, and there are more and more solitary times. So Ding Qi cherishes the time he spends with his little cutie very much, just like parents treat their own children.

Say hello to the little lynx, take the axe, and go and chop two more bamboos before it gets dark. He needed to make two cages, one for the rabbit and one for the pheasant.

The bamboo is dragged back, sawed into several pieces of length with a hand-saw, and then broken into strips of one centimeter wide. The cage is one meter long, 50 centimeters wide, and about 80 centimeters high, and two eyes are chiseled into the upper and lower positions of each piece of wood with a chisel, and each end is sawn into a tenon structure corresponding to the size and length. After piecing together into a frame, the bamboo strips were tied with rope at a distance of five or six centimeters, and a door was left for easy grabbing.

The two cages are made before going to bed, and after throwing the two animals into their respective nests, the doors are closed and they go to bed.

For the following week, Ding Qi's life was quite regular, and after feeding himself and a few animals every day, he went to burn charcoal, practice clay, make pottery, dry pottery, and catch small animals under the cover. He even drove an off-road pickup truck that would stop at some point, pulled back three truckloads of limestone to burn lime, and pulled back more than a dozen truckloads of stones to build a fence.

After pulling the last cart of stones, Ding Qi really didn't dare to use this off-road vehicle again. Remove the back seat, passenger seat, seat belt, and everything else that doesn't interfere with the vehicle's driving, including the four doors. Then I loaded a cart of wood, and it took a lot of effort to drive the car to the cave where the red fox mother and son were rescued, let's call it Pansi Cave.

First, the wood was placed in the middle of the cave, a fire was lit, and some leafy plants at the entrance of the cave were thrown to the fire, forming a thick smoke, which burned for most of the day, driving out all kinds of hidden spiders, scorpions, bats, snakes, and all kinds of insects in the cave, and then cleaning out all kinds of bones in the cave, removing the stones that were in the way, and then driving the off-road vehicle in.

Dirt bikes are items that are ahead of their time, and it's better not to be discovered by humans as much as possible. Using a jack and a monkey climbing pole, Ding Qi used a hacksaw to cut down two spring steel plates nearly 50 centimeters long, and all the others were left in the cave to be sealed for future generations to excavate. It's just that when archaeologists found this car, would they think it was a joke played by other people, how could there be cars in primitive societies?

Before leaving, Ding Qi specially sprinkled a thick layer of quicklime at the entrance of the cave to prevent some small animals from coming in again to make nests here. The spider spirit and the Zixia Fairy always lingered in his mind, lingering.

In the past week, Ding Qi has accumulated a large pile of charcoal, a large pond of slaked lime, a dozen dried clay pots, and captured two pheasants and three rabbits alive, expanding the scale of breeding, resulting in Ding Qi's daily workload increasing again.

Looking at the dozen or so clay pots in front of him, Ding Qi was also a little apprehensive in his heart, not knowing whether the next firing would be successful. For these clay pots, he specially prepared some grass and wood plasters on them as a glaze to increase the firmness and beauty of the pots.

Ding Qi was going to use two ways to fire the pottery, one was to use a ready-made ash kiln, and the other was to use the firing method of a cave kiln.

Needless to say, the ash kiln only needs to put smaller pottery products in it, add charcoal and burn it for two days in a row to make pottery.
