Lin Fan had a blue streak on his hand.
Not a tattoo, not a birthmark. It's the traces left behind by myself in another world.
He didn't know what that world was called, but he only knew that the sky there was lavender, that some people could retrieve objects from the air, and that some people could control fire. And the "Lin Fan" of that world was a member of a chaebol.
Every time we cross paths, we cross paths. Every time you travel, you bring back a new ability.
But time travel is not free.
The two worlds are merging. On the day the fusion is completed, many people will die - but some people think that it is a good deal to die a few people and change to a stronger world.
Lin Fan didn't want to be a hero. He just wanted to know what the blue lines on his hands were.
Until someone told him: "Stop checking. Someone will come looking for you."
