A certain scientific Saten Ruiko

The water source has been found, and the next step is to start setting up the shelter. As the sky is gradually getting darker and time is running out, Riri Saotome found two trees that are close to each other, stuck a piece of wood in the middle, and then placed a temporary wooden board cut by magic on one side, and also laid a layer of wooden boards on the ground. In this way, a simple shelter was completed.

Although it was a bit crude, it was the only way under the current circumstances. Anyway, she could now meditate instead of sleeping. In the past, she was worried that Aleister would find out that she had superpowers and could practice magic, and thus she would be involved in a lot of trouble.

Now that Aleister is not here, or even anyone else, she doesn't have that worry at all. Perhaps this is one of the advantages of being thrown here.

He lit a bonfire, ate some dinosaur meat that he had caught during the day, and boiled some hot water in a stone pot that he had made himself to quench his thirst.

Since it is just a simple campfire, I can't always use it like this to make tea or cook.

It looks like I have to build a simple stove tomorrow.

Sitting cross-legged under the temporary shelter, Riri Saotome stared at the campfire in a daze.

“I don’t know if I can go back… I hope Kamijou can give me some help.”

After all, humans are social animals. If they are alone for a long time, they will feel lonely to a certain extent. If the time is short, they may feel very free, but that may not be the case for a long time.

She didn't want to spend the long years alone in this primitive era.

Gradually her thoughts calmed down, her eyes slightly closed, her five hearts facing the sky, and her breathing became longer and longer. Although this place is still in the primitive period, but because of this, the spiritual energy in nature is more intense and pure.

As time passed, the sky began to gradually turn from dark to light, and Riri Saotome was awakened from her training by a natural alarm clock.

Gu~~~~~~~~

Rubbing its flat belly, it was now making serious protest sounds, reminding its owner that it was time to eat.

She opened the lid of the basket beside her, took out a piece of dried meat and took two bites, then picked up the stone cup to get some water to drink. She simply cleaned her teeth with charred wood, making them black. Facing the clear water, Riri Saotome bared her teeth in a funny way.

“Gurgle~~~Puff!!”

He spit out the black water repeatedly, and finally cleaned out all the remaining debris in his mouth.

After washing up at the river, Riri Saotome caught a fish, scaled it, and after having a heart-to-heart with the fish, she placed the fish on the campfire to keep it warm.

In the end, she got a grilled fish that was golden on the outside and tender white on the inside.

"Alas.....there is no salt taste at all."

While eating the all-natural grilled fish, Riri Saotome couldn't help but start to miss the seasonings in her original world, even if it was just salt.

But the good thing is that meat itself contains sodium, so she doesn't need to worry about lack of any nutrients in her body.

She has enough food and drink for the time being, so she has only one goal today, which is to upgrade her shelter.

The crude shelter was dismantled, leaving all the wood behind. Two deep pits were dug in the ground, and two five-meter logs were inserted into the pits, then reburied. At least two and a half meters of logs were left outside, forming a square with the two trees used last night.

The next step was to use local materials. She cut down all the trees that were in the way nearby and used them as wood to build a house. Although there were no nails or other things to fix it, she had some knowledge of carpentry, and after all, she had a lot of scientific knowledge in her mind, so building a wooden house was easy.

The area of ​​the wooden house does not need to be too large, only about fifteen or sixteen square meters. Of course, this is not the cabin she will live in forever. After all, it is only for one day, so this is just a temporary shelter.

The large open space she had cleared earlier was where she would build a larger shelter. When the larger shelter was completed, this small shelter could be used as a storage room.

By the time everything was done, half of the day had passed. I jumped high into the sky and confirmed the position of the sun.

"Time flies. It's already three o'clock in the afternoon."

I have to say that when there is something to do, time passes by like a flash.

In the remaining time, she started to make a stove. The construction of the stove was very simple. She just needed to prepare mud and stones. In order to prevent the mud from cracking during the burning, she deliberately used the following small magic to get some loess. After it turned into mud, she evenly smeared it on the surface of the stove. A simple stove was completed and it could be used after the mud was dry.

The next step was to upgrade her rough stone pot. Since the time was too short yesterday, she just dug a hole in a stone. Today she would carve it more delicately.

In addition to these, she also made a few pairs of wooden chopsticks. Although they are not as convenient as those made of bamboo, it doesn't matter. Of course, there are also wooden bowls, wooden beds, wooden tables, wooden benches, and other simple furniture.

He then performed a small magic on the wooden products to prevent them from rotting.

"Huh, it's finally done."

She didn't know when she could return to her original world, so she still had to prepare these basic daily necessities.

Now the needs of food, drink, daily necessities and shelter have been basically solved. As for the problem of clothes, she did not intend to weave them with leaves and vines like the primitive people. Instead, she used the dust-avoiding technique on herself, thus solving the problem of having nothing to wear after washing dirty clothes.

After doing all this, he took out a few pieces of dried meat again, heated them slightly by the fire, and started eating.

Surrounding the open space, she ate dried meat and used a wooden stick to draw a spirit gathering formation on the ground.

People's absorption of spiritual energy actually has a saturation point. As for the middle dantian and the upper dantian, these two places are used to condense the five qi and three flowers in the chest (privately set). It is a waste to use them to store spiritual energy. Moreover, as the realm improves, the dantian will naturally expand. Moreover, after reaching a certain realm, people can form an internal circulation by themselves and do not need any external supplementation.

The purpose of gathering spirits is to make the spiritual energy in the area more concentrated and easier to absorb, and it can also make ordinary people's physical fitness and lifespan stronger than ordinary people.

Of course, the effect will be even greater for people like Saotome Ruiko who can utilize spiritual energy.
