One Person Under One Person

The male protagonist Fang Wei and his friend Ti Long traveled through one person by chance, but it turned out that we were not the only ones who traveled through it? The time-travelers are all in trouble, what should I do? But God has a reason for letting me come. Even though I have come, how can I do it without making some achievements? Don't seek immortality or invincibility, just be a good person and do things with a clear conscience.
