Doomsday: Humanity shrinks 100 times

Chapter 181 Cold-Proof Clothing and Mobile Light Sources

When the six people returned to the base, they scared everyone else, mainly because Lu Yuning looked somewhat miserable.

Because the injuries were mainly internal, Lu Yuning could only deal with them briefly and then fell asleep.

When he woke up, it was already afternoon.

Although they were still tired, they planned to go out exploring soon, so there was still a lot to do.

In addition to keeping warm, they also had to find a way to make a night light.

Winter clothing is actually very easy to make, as they had already considered it before, namely down jackets, which is also the purpose of their collection of feathers.

The materials are spider silk and feathers.

First, process the feathers evenly, then use spider silk to make the shape of clothes, and then fill it with feathers.

The traditional method of making down jackets is to first cut the shell and lining into the corresponding shape and size, and then sew them.

During this process, fill in the feathers little by little.

However, this process is rather difficult for them. First of all, it is difficult to measure the cutting shape accurately, and it also needs to be sewn. Obviously, they do not have the manual skills to do this now.

So I just used my supernatural powers to generate a complete down jacket shell, and then filled it in.

The filling method requires a unique approach, using the stickiness of spider silk to stick the feathers on.

In fact, it is just replacing the sewing work with gluing, which is a job that requires patience.

So in the end, Lu Yuning was responsible for making the down jacket shell with relatively high precision, while the others were responsible for gluing the feathers.

After the feather filling is almost done, glue the lining on with spider silk.

It seemed like a simple job, but the team scrapped a lot of materials before they made a decent set of clothes.

But it still looks extremely rough.

There are two final difficulties. The first is still the size issue, including the size of the clothes themselves and the proportions of the sleeves and other parts of the clothes.

Finally, Lu Yuning came up with an idea. He first made a model of similar size by splicing wood together, so that each component could be measured first.

This makes it much easier to make it according to this size in the end.

The second problem is that the shell made of spider silk sticks together easily. The main body is fine, but the two sleeves are basically scrapped if they stick together.

In the end, due to the high scrap rate, they had to change the implementation method, which was to make the sleeves and the main body of the clothes separately, and then use the stickiness of spider silk to glue the two parts together.

After changing to this method, the success rate increased sharply.

Lu Yuning tried on the first down jacket she had made and found it was exceptionally warm.

Of course, it is still a bit difficult to rely on this alone to keep warm in winter, and you will definitely need to get some underwear later.

However, the thermal insulation effect of this down jacket is sufficient for the time being.

Some of the curious people tried it on and found that there were still some problems overall. Everyone also made some suggestions, but in the end the positive reviews were still relatively high.

After the second down jacket was made, Lu Yuning optimized some problems, such as smoothing the cuffs and collar, and the inflexible joints, using ropes instead of zippers on the clothes, etc.

After the improvement, it is indeed much more comfortable.

According to this template, everyone made a total of 10 sets.

The clothes they were wearing had been worn for almost two months, and everyone was very happy to have new clothes.

Lu Yuning rested for a while and then prepared for another production project.

According to their previous plan, they would first rush to the vicinity of the Starfire outpost during the day, and then try to find the general direction of the Starfire base by following the fluorescent traces after dark.

It is not easy to walk in dense grass at night. It is very difficult to move in the uneven grass without light. Imagine walking through the forest with your eyes closed. Therefore, we must find a way to provide night lighting.

The only means of lighting they have now is pine oil lamps, but it is obviously not practical to walk in the grass with these things in hand.

This thing stumped Lu Yuning. He thought of several solutions but rejected them all in the end.

First of all, in order to ensure that the pine oil lamp burned normally, the volume had to be large enough, which meant that the lighting tools they finally made had to be quite large relative to them.

But it is obviously impossible to move such a huge object in the grass, even with Chen Hong there.

In addition, the oil lamp will definitely fall over during the dragging process.

Seeing Lu Yuning at a loss, Zhang Muyan greeted her out of curiosity.

Lu Yuning explained the current problem. He did think of Zhang Muyan's ability to reduce friction to zero, but he still couldn't think of a good solution.

"So, if there is really no other way, we can only move forward in the dark," Lu Yuning sighed.

After hearing his narration, Zhang Muyan paced back and forth for a while, and seemed to be puzzled by the question.

He ran to the side and stared at the grass area for a long time, shaking his head and frowning.

Lu Yuning originally wanted to give up the production of the mobile light source, but he didn't expect Zhang Muyan to find him.

"I have an idea, maybe we can give it a try," he said.

"Huh?" Lu Yuning was stunned.

"Build a boat," Zhang Muyan said concisely.

"Boat?"

"Yes, ordinary methods are not very effective for us, but because of my special ability, perhaps we can use a method similar to a boat gliding on the water, and this dense grass is equivalent to water."

Lu Yuning widened her eyes, already understanding what he meant.

The grass area at the Spark Base is all bluegrass, which is relatively soft.

If you place a lightweight surface on the grass, the surface will actually be propped up, like a floating object in water.

The floating wooden board needs to slide forward, and the main resistance comes from two parts.

The first is friction, which can actually be ignored because of Zhang Muyan's special ability, so what they mainly need to solve is the second resistance.

The grass ahead pushes against the board.

The simplest way to solve the force in this direction is to change the direction of the force and convert part of the longitudinal thrust into force in other directions.

The method is actually very simple. Just pin the front of the wooden board into a pointed shape. This is actually somewhat similar to a boat sailing in the water.

The more Lu Yuning thought about it, the more feasible it seemed. He quickly said, "I think it's feasible. Let's make a hull first and try it out. If that works, then making oil lamps and the like will be easy."

Zhang Muyan nodded.

According to this plan, Lu Yuning hurriedly got busy.

But there is a new problem.

This straw boat has to be thrown directly onto the weeds. If it is made directly on the ground and then dragged in, the force conditions will be different.

So we have to find a way to get the hull directly above the weeds, and for stability, the boat has to be big enough.
