The so-called time travel also depends on luck.
If you are lucky, you can travel back and forth for 1,800 years. Even if you catch one randomly on the street and throw it back, it will be enough to kill a large number of people in an instant with the IQ and vision of modern people. Fame and wealth will be a thing of the past. When the time comes, you can choose any girl from far and wide, and your wife, children, and children will be warmed by the kang. It will be truly worthy of the kindness.
If you are unlucky, if you go back hundreds of years, like Li Qinghe, haha, you can only let more and more grass-mud horses happily dance the Riverdance in the great Gobi of the soul...
