Lu Ning was wrapped in a quilt and squatting in the tent, looking at the sky worriedly.

The clouds are getting darker and darker. Although there has been no snowfall in the past few days, the increasingly strong cold wind has swept through the mountains, turning the snow everywhere like haze. It is difficult to see anything from ten meters away. thing.

However, even in this weather, Lu Ning had to brave the strong wind and snow haze to walk out of the camp.

The sudden drop in temperature and the stronger wind caused the firewood to be consumed much faster than expected, and Lu Ning had to continue to go out to chop firewood.

The journey along this road was extremely difficult. The wind and snow not only blocked his vision, but the flying ice and dead leaves also made it difficult for him to open his eyes.

If Lu Ning hadn't been extremely familiar with this road, he might have gotten lost before walking halfway.

This time, Lu Ning didn't rest for a moment from morning to night. He walked back and forth five times from the camp to the giant forest. The harvest was more than twice as much as usual, but the physical energy consumed was more than four times as much.

"This is just the beginning..."

Lu Ning knew that he was far from ready to rest.

The cold winter has lasted for so long, and we don’t know when this snowstorm will end. The following days will become more difficult day by day.

Therefore, he must do his best to prepare at the very beginning, before all disasters have completely struck.

"If the wind and snow get worse in the future, I'm afraid this small tent won't be able to block it... We have to think of a way to strengthen it, and even... maybe we can use pottery to build a wall, which may be able to block the wind.

"There is also a campfire. The wind is getting stronger and stronger, and the flint and steel have been used up. We must not let the fire go out, and we must make more preparations for this."

Lu Ning turned his brain and went through what he needed to do one by one.

"I have learned almost all the methods of finding and firing clay recorded in the book, but I haven't practiced them yet. I don't have much time to accumulate experience now. I can only hope that after staying here for so long, I can improve my hands-on skills." The improvement is obvious enough.

"The last thing is food. Well, don't worry too much about this. I have accumulated a lot of food from hunting and farming these days, especially the green potatoes harvested from farming. It shouldn't be a problem to last for more than half a month. We can go there in two days. If you collect a bunch, it will probably be enough for the next meal."

Lu Ning used tree branches to write down his goals on the snow, and his originally depressed and worried mood revived.

There are still many things that can be done.

Next is the usual time for material distribution.

When the arrival of the blizzard was announced yesterday, Ghost clearly mentioned the change of the manufacturing list, so Lu Ning was very much looking forward to it.

"Data reconstruction transfer in progress.

"Special assistance materials: charcoal (black) manufacturing process drawings have been distributed to the captain, please check them.

"The production of the next aid material is being stepped up. The estimated completion time is: 24 hours. Captain, please wait patiently."

"Charcoal making?"

Lu Ning was stunned for a moment, then reacted and was extremely surprised.

Taking the blueprint from the light beam, Lu Ning eagerly read through the pictures and text recorded on the blueprint.

Charcoal is also a fuel with a long history.

Compared with ordinary firewood, charcoal has many advantages.

Due to its loose and porous structure and the removal of moisture and impurities during the firing process, charcoal is easier to ignite and burns more fully, with less choking soot and safer.

In addition to being used for combustion, charcoal has many more uses. As long as it is used properly, even ordinary charcoal can be used for antisepsis, deodorization, water purification and many other tasks.

Of course, charcoal is divided into many categories and grades, but those high-grade charcoals have higher requirements for raw materials and manufacturing processes. The drawing in Lu Ning's hand only records the method of making the lowest-grade "black charcoal".

"First of all, we need a mud kiln that can burn charcoal. Well... I'm afraid it's too late to make one now, but we can simply dig a stone kiln from the cliff in the southwest.

“And you can mine clay there, so you can kill two birds with one stone.”

Lu Ning looked at the drawings and quickly came up with an idea.

Anyway, it’s dark now and I can’t go out, so why not get started now? Lu Ning immediately slapped his thighs and stood up, carrying a shovel and various tools and heading over there.

The cold wave comes from the north, and the wind direction is mostly northerly. The terrain in the southwest of this mountain peak is relatively gentle and well-proportioned, and there are cliffs blocking it in the north, which can be said to be a natural haven.

As mentioned before, Lu Ning's new farmland was opened here - and now he plans to open up another place for people to live on the cliff below the farmland.

The first step is to dig a large enough gap into the cliff from this piece of land.

The soil here is relatively soft and rich in moisture, but it is also frozen very solid due to the low temperature.

Lu Ning built a new campfire here, letting the flames roast the cliff to thaw, and it soon became loose enough to be pried with stone shovels and stone picks.

Lu Ning wielded a shovel and a stone pick and started working immediately. The excavated soil and rocks were thrown directly back and down the cliff.

He worked almost without any rest for half the night, until the ghost told him that it was already 5 o'clock in the morning, and he returned to the tent in a daze.

Before going to bed, there was only one sentence left in his mind:

Have you ever seen the sun at 5 o'clock in the morning in another world?

Oh, I haven't seen it either - because the sky is as cloudy as the bottom of a pot, and the sun can't be seen.

He didn't sleep for long. Lu Ning woke up at 8:30 in the morning, got up, put a handful of snow paste on his face to refresh himself.

"hiss……"

Lu Ning was shocked by the snow in his hand, and then he realized -

The cold wave is coming.

Although the campfire not far away was burning brightly, and Lu Ning was wearing thick fur clothes, he could clearly feel the cold air around him seeping into his clothes, making him shiver.

Usually there would be birds flying across the sky from time to time, but today the whole world was completely silent, with no life except the howling cold wind and the whining sound blowing through the mountains.

"Ghost, what's the temperature now?"

"Twenty-seven degrees below zero, Captain."

The ghost's answer confirmed this.

The temperature dropped by a full seven degrees in just one night. No wonder the feeling was so obvious.

The cold wave has officially arrived in this area, and according to Ghost's prediction, there will be further cooling.

Forget it, don't think about those annoying things for the time being and just follow the plan.

Last night, she stayed up doing physical work until 5 o'clock before going to bed. Lu Ning was very hungry now, so she put her worries behind and wanted to get something to bake and eat.

When Lu Ning came to the place where the food was stored next to the firewood stack, he was shocked to find that the green potatoes, hot herbs and various vegetables piled on the ground were covered with white frost and their outer skins were gray and rotten.

The color is so bright that large chunks of it have turned black and rotten.

Lu Ning had no time to think about anything else and rushed to his small vegetable garden to check the situation.
