Through Time Travel, I Became My Ancestor?

Blue Star has an abnormal climate, constant natural disasters, and biological mutations. The surviving humans have moved to the last piece of pure land, the roof of the world, because it is said that there are spaceships there that can leave the planet. Qi Yang was also one of them. In the end, he was exhausted and collapsed at the foot of the destination mountain. When he woke up again, he found that he was on another planet. Slowly, he discovered that the humans on this planet were the descendants of the humans who successfully escaped from Blue Star, and he might have become his ancestor...
