4.6 billion years ago, Earth was born.
3.8 billion years ago, oxygen was born.
800 million years ago, plants were born.
200 million years ago, dinosaurs were born.
When Yi Shi woke up, he found himself transmigrated to the early days of Earth. The planet had only existed for 100 million years. Volcanoes erupted constantly, and there were no oceans or oxygen.
His body couldn't adapt to such a hostile environment, and he died on the spot.
It wasn't until his second resurrection that, protected by the System's golden finger, he managed to stay alive for ten minutes.
Through repeated cycles of death and resurrection, Yi Shi finally learned how the System worked.
If he wanted to escape the cycle of dying and coming back to life, he had to keep exploring and evolving. It was the only way to survive in this utterly hostile environment.
[Note]
1. The author knows nothing about science, and none of the worldbuilding can withstand scrutiny. It's all made up.
2. Don't get too hung up on the geography or biology. This novel has no connection to reality.
3. No suffering for the protagonist. It's a satisfying progression story. No intelligent life forms other than the protagonist appear, and he is alone until the end.
