In the next period of time, Luo Ji can be said to be immersed in the pulley set, while thinking about the design of the city gate, feeling that his brain cells are dying every day, and this day is both fulfilling and maddening.

Such maddening days passed day by day, and the weather was getting colder day by day, and in the early morning of this day, Luo Ji, who was asleep, suddenly shivered, "Okay, so cold......

Subconsciously tightened the animal skin quilt on his body, at this time Luo Ji almost wanted to wrap himself into a zongzi, but he couldn't dispel the swept chill at all, and the sudden sharp drop in the early morning woke up the Spiegel tribe at night.

Wrapped in the thick animal skin on his body, the moment Luo Ji got out of his tent, the cold wind whistling in his face was like an ice blade, and the feeling of blowing on his face was no longer cold, but painful!

This kind of pain that the skin is almost scratched by frostbite makes Luo Ji, who has gradually adapted to this ice and snow, once again clearly feel the harshness of the living environment in this era.

It was not yet dawn, but almost the entire tribe was awakened by freezing, and the crying of children could be faintly heard, Luo Ji clenched his teeth, and the uneasiness in his heart became stronger and stronger, driving him to shout, "Hurry up and move all the coal that was hoarded before to make a fire, and then cook a few more pots of radish soup." ”

The temperature is so low that I can't sleep this night, and if I sleep again, I'm afraid I won't be able to wake up! Under Luo Ji's command, the Spiegel tribe quickly lit one fire after another, and the temperature generated by the burning of coal made the temperature in the tribe rise slightly, but Luo Ji was not optimistic at all, it was too cold, even sitting next to the fire, he felt that he was about to be frozen, and even his breathing became painful.

After the radish soup was cooked, he drank two bowls in a row, and the whole person finally felt a little better, "Cook some more, let everyone in the tribe get a bowl of soup, and after the soup is drunk, boil hot water, don't stop." ”

After speaking, Luo Ji stood up from the fire wrapped in animal skins, "Don't sit, everyone, stand up and move around the fire more, so that your body can warm up a lot!" ”

Luo Ji was very scared in his heart, he was afraid that some of the people of his tribe would freeze to death, or get sick, and the disease might show symptoms of transmission, and at the same time, the sick people would not be able to work, which would lead to a decrease in the work efficiency and development speed of the tribe, and then the food supply and wood fuel would also become insufficient because of the decline in work efficiency, and everyone would not be able to eat enough, and their bodies would become weak, and more and more people would get sick, completely falling into a negative circle, and finally, going to destruction......

Shaking his head vigorously, throwing this bad guess out of his mind, Luo Ji's originally gradually perfected development plan was instantly disrupted by this ruthless nature.

What can he do now? What else could he do besides having people make a fire to make soup and remind his tribesmen to move their bodies and maintain their body temperature? A deep sense of powerlessness arose.

"Find a way! Hurry up and figure it out! Sitting by the fire, Luo Ji almost forced his brain to start working, the weather was too cold, people couldn't sleep at all, but it was impossible not to sleep for a big living person, right? At the same time, if you can't get enough rest, where will you have the strength to work the next day? This is simply the entrance to a negative cycle! So, the problem of sleeping and resting must be solved!

"Make a fire in a tent?" As soon as this thought arose, he was crushed by Luo Ji himself and thrown into the non-recyclable garbage can, he was really stupid from freezing, the gas produced after the combustion of coal is a harmful substance, he still knows this kind of common sense, lighting a fire in a tent, it is warm, but it is not far from death.

No, it was so cold, he felt like his brain was about to stop thinking, "Damn! I really want air conditioning and floor heating......"

This thought was even more than lighting a fire in a tent, and he thought about it casually in his mind, but before he could laugh at himself, the expression on Luo Ji's face suddenly froze, "Wait, floor heating?" ”

There was a faint flash of inspiration in his mind, which was a very subtle feeling, but Luo Ji knew that he might have found a breakthrough!

Luo Ji called two tribesmen to quickly get into his tent, signaled the two to dig a rectangular shallow pit on the ground in the tent, and then asked them to take two wooden sticks, pick a few burning coals from the fire outside and throw them into this shallow pit, and then fill in the shallow pit, and finally spread the animal skin on it, and finish!

After waiting for a while, Luo Ji drilled into the hide of the beast, damn it! Is this heaven?! Leave me alone, I've been here this winter!

However, the actual situation was that early the next morning, Luo Ji still got up early as always, even earlier than usual, worried, worried about the situation of the tribe members, he couldn't sleep at all, coupled with the emergency situation in the early hours of this morning, he was obviously not sleepy at the moment, and his whole spirit seemed a little sluggish.

After dawn, with the rising of the sun, the temperature warmed up slightly, making people feel a lot more comfortable, Luo Ji, who had not heard any bad news for the time being, breathed a sigh of relief, thinking about it carefully, he actually didn't need to be too pessimistic, he did a good job of dealing with it yesterday, people who lived in ancient times have withstood the test of so many harsh environments, and their physique should not be able to hold up even for a while.

However, thinking about it, when everyone gathered for breakfast, Luo Ji still emphasized to everyone that if anyone feels unwell, they must say it as soon as possible.

At the same time, for the sake of insurance, Luo Ji also changed the original two meals a day to three meals a day, and added a hot soup to ward off the cold at noon, although this will significantly increase the consumption of ingredients in their tribe, but as long as the manpower is preserved, the food problem can always be solved.

In addition, what also made Luo Ji a little worried should be the situation on the side of the Black Rock Tribe, because this sharp cooling has increased the importance of coal again, and the demand has also increased, although during the previous period, Luo Ji has been hoarding the coal mined by the Black Rock Tribe, but according to the consumption last night, he really doesn't know how long it can last.

In this case, the top priority of their tribe had to be changed, Luo Ji asked the members of the logging team to temporarily put down the work at hand, and then divided them into two groups, one group temporarily joined the mining team and rushed to the Black Rock tribe to speed up the mining of coal, and the other group rushed to the farmland where the white radish was found, so that they could dig more white radish or other vegetable food back, and the development focus of the entire tribe began to shift towards food and coal.
