Yulin pondered for a long time and couldn't help but think about it.

First of all, what I saw and heard on the top of Baizhang Cliff that day was so hazy that it could be said to be both real and illusory, and Yulin couldn't tell whether it was a dream or a wake-up; Moreover, how did he fall from the top of a cliff at such a high level and be unscathed, and there was not even a scratch or scratch on his body; Also, is it really a coincidence that the tiger girl was born here and happened to hide in her own baggage and entered her own home together? Finally, since I got home that day, many subtle changes have taken place in myself: the amount of food I eat has increased dramatically, two or three times larger than before. Also, the body recovered very quickly, almost overnight after returning, and even felt stronger than before. And there is a vigorous vitality all over the body, as if there is nowhere to vent the strength of the body, and the limbs have a slight expansion and eager to try.

The tiger girl couldn't bear it for a long time, jumped up in the book basket, and was at a loss to look at the dry food with meat in the next compartment. The restlessness in the book basket interrupted Yulin's contemplation, and finally dragged him out of a pile of mysteries, he took out the dry food, and handed it to Hu Niu without hesitation, but did not make any requests, such a sudden surprise made Hu Niu unable to adapt for a while, and did not take it, only looked at Yulin with inquiring eyes.

Yulin put her on the lid of the book basket, faced herself, and said while watching her feast: "Let's answer the question today and don't divide one, two, three, you can search the memory in your head, and tell me what the situation is there, it must be different from us here, right?" ”

After eating in three bites, the tiger girl seemed to be unfinished, and her delicate tongue swirled to search for the food scraps in her mouth, and said, "I want to check it out to see if there is anything you are interested in." Then, the two big ears began to rotate left and right.

"Are you thinking about it?" Yulin was puzzled.

Tiger Niu nodded and booed Yulin not to disturb her.

After only a moment, Tiger Girl's ears stopped spinning, and Tiger Niu sighed and said, "I have found some information about our hometown from my existing memory, and now I will pass these things on to you in my brain."

So the tiger girl put her head against Yulin's forehead, and Yulin suddenly felt a slight tingling sensation from her forehead to the entire brain in an instant, and her spirit was also shocked, and then a string of lines of words appeared in her brain.

The text was very long, and Yulin roughly skimmed through it.

It turned out that it was recorded from ancient books that Hu Niu's hometown was originally beautiful and picturesque. But then the war came, the whole mountain was razed to the ground, the rivers dried up, the trees, birds and beasts were all extinct, most of the surviving creatures were hiding in underground caves, and the "people" were seriously troubled by the lack of food, water, medicine and medicine, and finally the plague epidemic, most of them died one after another.

I don't know that after hundreds of thousands of years, the bodies of the remaining people have changed, they have become short and thin, and their speech is almost silent.

Yulin couldn't bear to look at it anymore and said: "Hu Niu, you simply say what is different about the 'people' you have there, pronounce it in your brain, and don't show me the text."

So the tiger girl told the story.

In the world of tiger girls, there is no big difference between "people" or "beasts" and "birds", everyone is facing a lack of food, so they have to expand the "edible" range of food, generally eat three or two kinds of low green plants, but this plant is cold, often eaten is weak and cold, vomiting and diarrhea. Therefore, "people" collected a unique mineral soil underground and added it to plant food to neutralize its coldness, so that it could survive.

However, in this harsh environment, "people" gradually adapted and slowly evolved, and even developed a civilization (the memory loss of relevant civilization materials is omitted for the time being).

In the world of tiger girls, "people" are also divided into two sexes, and the way of reproduction is very different: when the two sexes who are attracted to each other want to have children, they do not need to live in the same room, and the children can be "customized" according to the wishes of the parents,—— parents according to their own wishes, the future child's height, weight, body shape, facial characteristics and other information, through full discussion, modification, and finally determined, and then the parents meet in the way of meeting (that is, two people's foreheads touch together, Then the forehead contact part secretes a fluid, and finally until this fluid is absorbed by the mother) begins to give birth to a new life in the mother's body, usually a gestation cycle is two years, but in the case of food shortages or environmental emergencies, the mother can end the pregnancy early, or give birth or "throw" the child.

Yulin listened, seemed to understand or not, and asked, "So you usually have to eat soil?" ”

"It must be, otherwise it will be difficult to survive"

Yulin asked again: "Will there be errors in the way they meet and have children, so that they will have an impact on the children?" ”

"Of course, I'm in... We have seen children who are eight feet tall, with three eyes, a nose on the forehead and nostrils pointing upwards."

"In this way, does he not dare to go out without an umbrella on a rainy day?!". Yulin smiled.

The tiger girl couldn't laugh and looked at him with disgust.
