On the first night of moving into the tulou, Xiao Yiran had insomnia. It was a clear night, with a deep sky full of stars and no moon. Xiao Yiran sat in the room, looking up at the Big Dipper through the window. For the first time, we consider the issue of time and space, the past and the present are the universe, and the upper and lower left and right are the universe. He died in time and space tens of thousands of years later, but was reborn in the ancient era of the Paleolithic. How did it happen? People must have a soul after death, otherwise they would not be reborn here. But will the soul really go to the underworld after death? If you are not born again, do you want to go to hell? Or is there no underworld at all, and if there is no accidental rebirth after death, will the soul slowly disappear?

"It would be nice if there was a hell of hell, whether it is ancient or modern, it is the only place after death, and when you are reincarnated, you must be able to choose the era of reincarnation, right? If this is the case, when you die, you must choose the right time to reincarnate in the arms of your mother and be your parents' daughter again. In the previous life, I didn't do my filial piety to my parents, and if I do it again, I must double the compensation for my parents. ”

Thinking about it, Xiao Yiran felt that this seemed to be a paradox. If you are reborn in the wilderness, will the future history still be the history you read in the textbook? Besides, it is said that after death, you have to drink Meng Po soup, and if you drink Meng Po soup, you will lose the memory of your previous life, so how can you choose the era of reincarnation? Even if she happens to become the daughter of her parents again, she has no memory of her previous life, but she is still an ordinary family of three.

In the end, Xiao Yiran's thoughts revolved to matter and dark matter. Dialectical materialism says that matter is objectively existent, and scientific research before rebirth proves that there is indeed dark matter, that is, the opposite of matter. So what should be the definition of dark matter? Ancient Chinese philosophy has always explored the relationship between the virtual and the real, or the relationship between yin and yang. What does it mean to say that "all things are negative yin to embrace yang", and to say that "virtual is ready to be used", is it saying that yin and yang, virtual and real are two aspects of an organic whole?

A meteor suddenly crossed the sky, interrupting Xiao Yiran's chaotic thoughts.

"No matter what, since you are reborn here, you have to live vigorously, although it is as short as a meteor, you must also live a brilliant life in an instant."

Xiao Yiran made up his mind that he would no longer look ahead and backward, and when it was dawn, he would hand over all the modern knowledge and skills he had mastered to his clansmen, so that his clan could rise rapidly in the shortest possible time to prevent it from being wiped out by other powerful races.

The first thing that Xiao Yiran thought of was a bow and arrow. At present, the people here only use throwing weapons such as javelins, and there are no long-range attack weapons, so it is easy to have a brutal battle in short-range combat in hunting or war. There is only one problem, that is, how to ensure that the bows and arrows made by oneself are not circulated before the rise of the race.

"Ann, how can we prevent the secrets of our clan from leaking out?"

"You can make your people swear before the gods."

As soon as the day dawned, Xiao Yiran asked An to gather all the people in front of the stone that depicted the image of the dragon.

"Since you have elected me as the chief of your clan and your chief, it is my duty to protect you and to provide you with food and shelter. Now we have rice, soybeans, salt, and tulou in our clan, and we have to make clothes next. When we become rich, we will inevitably attract the covetousness of other races, so we must have our own warriors and our own weapons. Here, I ask my people to swear to the great deity, the dragon, that they will never divulge any of their secrets, or they will be punished with the severest punishment from the great deity. ”

When all the clansmen swore to the portrait of the dragon on the stone, and knelt down in front of Xiao Yiran again, Xiao Yiran left An and Lin, painted the appearance of the bow and arrow on the ground, carefully explained it to the two, and asked them to choose the most faithful and reliable people from the tribe to participate in the work of making zuò bows and arrows.

When a month later, after the first batch of five bows and arrows were ready, Xiao Yiran asked Lin to tie a scarecrow with straw, and he took the bow and arrow to make a demonstration for Lin, so he handed the bow and arrow to Lin and asked him to try. Men may be born warriors, and Lin only practiced two or three arrows before he learned well. It's just that just shooting a scarecrow still doesn't show the power of a bow and arrow. Xiao Yiran asked Lin to teach five more people, and then sent them to hunt in the mountains and forests with bows and arrows, and only in hunting could they show the great power and advantages of bows and arrows.

In the evening, after the five people came back with the prey they had shot with bows and arrows, they came to Xiao Yiran for the first time, knelt on the ground, and once again performed the five-body bow to the ground, it is not difficult to imagine the excitement in the hearts of the five people at this time. Beasts can be shot lightly, so in wartime, you can shoot your opponent far away, isn't it invincible?

With the maturity of the second batch of rice and soybeans, Xiao Yiran's ethnic group has basically solved the problem of eating. During this period, more than 20 people came from the nearby Eagle Clan, Snake Clan, and Tiger Clan. Among them, there are adult men who came here to hunt, and when they saw that the dragons were so rich, they took the initiative to choose to stay. There are also people who came with Lin at the beginning, and when they returned to the clan, they secretly brought back their closest people. In the five months after the completion of the tulou, Xiao Yiran's clan had reached seventy-one people, in addition to more than 20 people from Wuji, there were also seven or eight young children born to women in the clan during this time.

Of course, there was also an adult woman in the middle who died due to dystocia during childbirth. Siu Yiran witnessed the whole process. Xiao Yiran, who had no common sense about production, could only watch the woman die painfully. In such a backward era, having children is the greatest danger a woman faces in her life.

For a long time after that, Xiao Yiran was worried in his heart. She couldn't imagine what it would be like to give birth in the future. Even, in Xiao Yiran's heart, he has already begun to plan that he will not be able to have children in this life.

Xiao Yiran, who is almost sixteen years old, also began to think about his marriage from time to time. The feeling of the ceremony of becoming the leader made Xiao Yiran, a new body that had entered puberty, have a desire for the opposite sex, and Xiao Yiran was already a twenty-seven-year-old mature woman before being reborn, and she was no stranger to that woman. Xiao Yiran has been observing the men in the group, especially the first twenty-one, and has been trying to find out the three people who kissed him differently in the ceremony of becoming the leader, especially the one who touched his bulge with the tip of his tongue, but Xiao Yiran has not been able to do so.

I have to admit that the men of this era are very athletic. The bronzed skin and bulging muscles in the limbs and abdomen are more attractive to women, especially Xiao Yiran, who was tired of seeing cream Xiaosheng before being reborn. In addition, the men of this era can't cover the Weijian below with just a few leaves, and when they loom, it will always cause Xiao Yiran's heartbeat.

Although An has always lived with Xiao Yiran, Xiao Yiran still found that at night, An would often sneak out to meet Lin Yiran. Once, after An came back in the morning, he asked Xiao Yiran:

"Sister, the men in the clan are very in awe of you, and if you don't nod their heads, they don't dare to take the initiative to come to you. If my sister has someone who is optimistic, sue me, and I will let Lin lead him. ”

Xiao Yiran shook his head and didn't say anything. In my heart, I thought that although people in this era put childbirth first, as for feelings, they seem to be dispensable, and there are only a few cases like Lin He'an. However, Xiao Yiran still didn't want his first time to be taken away by a strange man with no emotional foundation.
