After Mars had eaten and drunk enough, he thought about taking a good rest.

But with his own father here, Mars didn't dare to be so idle.

Then slowly raise yourself to get fat.

So what Lawrence does, he does.

At this moment, Lawrence sat on the edge of his bed, looking outside, he still had thoughts about the food just now.

So Mars could only sit.

Mars, who sat down, quickly saw the reminder from earlier.

But it was time to eat the barbecue just now, so Mars and Ben didn't care.

Now that I have a short break, I just want to take a look.

"The first time you use exclusive materials to make cooking utensils, and enjoy the success of food, you will be rewarded with 0.3 attribute points!"

"Mars Morley - Constitution: 1.5, Stamina: 0.9, Remaining Stats 2.1!"

Originally, Mars's attribute points were only 1.5, but the first time he made a bed, he gave 0.1, the first time he made a cutlery, and the first time he made a weapon stone spear, he gave 0.1, so now, the attribute points have a terrifying 2.1.

With so many attribute points, Mars hesitated for a long time, thinking about adding all the attribute points himself.

However, after taking a look at his father, who had always wanted to protect him, Mars felt that it was better not to be too anxious, and if he grew up too fast all of a sudden, Lawrence's mood might change accordingly.

However, according to Mars's plan, as long as he can still obtain attribute points, then he will start to increase, and he will not increase all at once, but will increase it several times.

After possessing this attribute point, Mars found that his physique would not change at all because he became stronger, and it was likely that he would not change again in the future, so he could only increase it himself in this way.

This is different from the humans of this world, because they will change their physique with their age and other environmental influences, but Mars's is qualitative, and he can only make himself stronger from the attribute points rewarded.

Eventually, Mars saw his father lying down to rest.

He also stopped sitting and made himself more comfortable lying down.

There is nothing else here.

Mars and Lawrence basically slept on the stones.

Fortunately, the temperature is okay, otherwise sleeping on it would be torturous.

Mars, who was lying down, looked at the stone house.

Then a good suggestion came to mind.

"Father, in the afternoon I will add the passage to the stone house, so that we will have light in the evening. ”

The dark night makes people feel dazed.

At this time, Mars knew that he could not make biogas lamps himself.

However, getting a light lamp will do the trick.

Then you can also create that kind of transparent glass around the lamp, so that it will not be blown out by the wind.

Mars thought so, and then it became more and more feasible to make a bigger lamp outside.

So that in the dark, there will be a guiding light here.

That is, it is similar to a lighthouse-like function.

Of course, Mars didn't show the way to the other humans, but wanted to be able to see the outside with his father at night.

Ideas are always good ideas, and the more Mars thinks about it at this time, the more he feels that he can't stop at all.

"Mars, if this continues, our box of matches won't be available for long. ”

The number of matches, Lawrence has counted, and now that he consumes so much every day, it will definitely not be enough in the long run.

There will be no ignition device.

"Father, in that case, let's make a device with a permanent source of fire and let it burn forever, so that we can have fire forever. ”

Lawrence was talking about a very important issue, and Mars felt that he had to come up with more ways to deal with it at this time.

Seriously, this fire-starting tool itself is still too little.

"Burning it all the time will fix it in one place, and we won't be able to draw the fire into the stone house!"

Lawrence thought Mars was saying it well, but there were a few limitations.

At this time, Mars began to think quickly, thinking about how to better divert the fire.

Soon, Mars had an idea.

As a man who can use stones as tools, he also thinks of stones.

"Father, I make an empty stone, and then store some of the burning gas in it, and when I need to light a fire, I use them to start a fire!"

Mars said this, in fact, he still had an idea in his heart.

That is, after filling the gas, he can also compress it, so that he does not have to worry about the gas not being strong enough to ignite.

As long as it can ignite a fire.

It's not a lot of effort to make this thing.

And you can make a lot of it, so it's easy to use.

With Mars's thoughts, Mars felt that this thing could be made into a small torch, and in this world, there can be light, and there can be light that will never be extinguished, what a magical event it must be.

"Mars, we can try it later, and if we can, we'll have an endless fire. As for the fish that need to produce gas, we can catch more. ”

Lawrence already thought Mars's proposal was very good.

So he gave Mars a piece of advice for sure.

With his father's approval, Mars's confidence grew.

It's a big project, and it's very easy to make it yourself.

But there are many of them that I am not familiar with, so I can only give myself more time to try little by little.

At noon, the sea is the same as ever, and it is impossible for humans to be exposed to the sun, so if there is a shady place, they will hide.

Since the stone house, Lawrence and Mars have not been exposed to the sun for a long time.

On the contrary, after sleeping in the stone house, I felt very comfortable.

Regardless of the sun outside, it was not until the afternoon that the sun was no longer so hot, and Mars and Lawrence would come out.

Now they're going to get food.

However, having already told his father what he was going to do, Mars went to make tools and lamps, while Lawrence went to catch fish.

Because this lamp needs the gas produced by the fish, in order to keep it on, it is necessary to get a lot of fish.

As long as the place where the fish were placed was big enough, Lawrence wanted to have it all stocked.

So he catches a lot of fish.

As long as you see it, don't try to run away.

Mars's idea was to lay a pipe in the stone house so that the biogas could be transferred directly from the digester to the stone walls inside the house.

Then Mars will make a lamp at the location of the stone wall.
