Farewell Apocalypse

The history that has been passed down since ancient times is only one side of the coin. There is another world hidden in the vast historical books. On the back side of the main world, aliens struggled out of the shadow layer and launched revenge on humans. The decisive battle is approaching, and the secrets that have been hidden for thousands of years can no longer be kept. Two teenagers, one from the ordinary people, accidentally activated an ancient bloodline and got involved in a strange struggle; the other, whose life experience is a mystery, entered the battlefield early and cut through all obstacles with a knife. They met in a seemingly ordinary college and witnessed the changes in the world.
