The gloomy sky was completely uneven, and Yi Hai didn't know how the plants in the wild grew without photosynthesis... Maybe they were new-shaped and mutant plants, after all, they were specially marked as inedible types on the survival guide.

In the fortress, food is actually not expensive, because although humans cannot eat those plants, the milk rats raised can be used. Those milk rats and some small animals are basically the source of food for this fortress. Who makes it easy to raise mice?

What is really missing is plants. You basically don’t think about vegetables, fruits, etc., only fungi, and Yihai and the others are not able to buy them on the market. Of course, there are some edible wild vegetables, but they are also very expensive. Anyway, they don’t want to eat wild vegetables. At least they can survive by relying on the nutrients issued by the tissue that doesn’t know the name yet, but they just can’t fill their stomachs.

"It rained all day yesterday. The sewer system in this city is very perfect."

It was clearly raining a day and a night, but there was no place for water accumulation on the ground. It can be seen that the sewer system of this fortress should be quite complete. As for where the rainwater goes, it is not something Yi Hai would think about. It is actually not far from the river, but there is no river directly passing through this fortress covering an area of ​​6,000 square kilometers. It is estimated that the water needed for daily life should also be obtained from the rainwater.

There was no clear sky after the rain, and thick dark clouds occupied the sky. Except for the occasional optical fiber, there was no way to judge time. The other party didn't even think about it, such as the night sky, the clear sky, etc.

Just like Zero, born in the world after disaster, even how to survive is a problem. As for the night and the starry sky, they can basically only be seen in books, and they must also be books with pictures. In this case, almost no one will stand up to provide guidance and education to children without parents. Zero can even write his own name, a real illiterate person.

Therefore, teaching Zero to learn has also become one of the interests that Yi Hai suddenly developed after coming to this world.

As a psychologist, Xingcai said that now everyone is overwhelmed by invisible things. In order to prevent the unconsciously revealed spirit of Abuhos, it is best to find something that can temporarily relax and do.

Of course, it is not to let everyone give up on tracing what happened twenty years ago and what happened in Abuhos.

But in these twenty years, too many people died. Too many secrets were buried forever, and it was almost impossible to find out what happened twenty years ago. And to trace Abuhos, or to use the summoning spell, the information of the person summoned Abuhos was a bit illusory.

Xingcai didn't get much information, and the outer god was too far away from everyone. She was completely helpless about the current situation. Although the arrival of the fallen sons who reaped their lives was imminent, it would not come immediately. Therefore, during this period of time, Xingcai became a bridge between the four of them and the unknown organization, responsible for contacting each other and obtaining information.

She is obviously a psychiatrist, but she prefers to chat with some nervous guys and see their status than to treat people. However, Xingcai just looks at it like this and will not treat the other party. She is the kind of person with a very bad taste.

Pro often followed Xingcai, for fear that this guy who was off-line suddenly made something to stop him. Even if he couldn't stop him, he could not notify Yihai and Ximier in advance. So as not to have no preparations at all.

Simier went to survey the terrain. Because the aperture was raised on the outside of the fortress, the city only allowed people to enter and did not allow people to go out. Simier had no way to go out, so he ran to the guards every day to get close to him. Not to mention, he actually got some useful information, such as the layout of the city, such as shelter, and some bookstores that could not be found on the map.

Yi Hai was teaching Zero learning while running to the bookstore with Simire.

Although the major is not right, as a doctor of mystery, he is still a doctorate, so there is no problem in teaching others to read and write. The texts in this world are common to Yi Hai and the texts in the world, so there is no need to worry about it. What Yi Hai teaches is not very profound, it is just some simple texts and simple applications in mathematics.

As long as it is enough to make Zero survive.

He would not be crazy about teaching advanced mathematics or something. After all, there are always one or two things in this world that cannot be overcome. You must know that if a person is forced to do anything, except for advanced mathematics.

Of course, in addition to these, Yi Hai will also teach some more practical things, that is, what you need to survive in this world and combat skills. However, Yi Hai himself does not have very good combat skills. He mainly relies on his armor to recklessness. If he really fights head-on, he may not be able to beat Simire.

"Well, I can't teach you too much. This thing is generally based on talent... and I'm not much better."

Looking at the target not far away, Yi Hai and Zero had a pistol in their hands, and there were several shells under their feet. Of course, what was more unified was that there were no bullet holes on their targets. Yes, all five bullets were off the target.

Simere, who was watching from a distance, was already laughing out loud.

"This is all for today's training. Simire said that good marksmanship is fed by bullets. We don't have so many resources to get more bullets now."

After putting away the pistol, Yi Hai took out a long sword, which was a straight sword, which was similar to Yi Hai's evolution trustee. However, Yi Hai's evolution trustee can be used with one hand, and this long sword is obviously used with both hands.

"I asked them to help me with this, which is a reward for your serious training these days."

Perhaps because of his talent, Zero has made rapid progress in using weapons for hand-to-hand combat, so Yi Hai is also thinking about giving her a weapon. Although this weapon is not of high significance in actual combat, after all, without light, the monsters outside are basically invulnerable. In the fortress, everyone is basically holding guns, which can only be said to be a means of self-defense.

"Thank you, teacher!"

Zero seemed very excited when he took over the weapon from Yi Hai's hand, but as soon as her words of thanks fell, Yi Hai disappeared from him. No, it should be said that she disappeared from Yi Hai's face.

‘Woo-Woo-Woo-Woo-Woo-’

A harsh alarm sounded across the sky. When Yi Hai came to his senses, he found himself in a strange space. In the sky, a black sun cleared away the dark clouds that had always been covering the sky.

[Doctor! It is the son of the fallen! This is the harvest space, and the selected sacrifices will be pulled into the harvest space.]

Just like the information I saw in the book before, when the Son of Fallen Arrives, the selected offerings will be taken into a different space, and this different space will continue to expand and inhale more lives. Only a very few lucky people can escape from this different space.
Chapter completed!
