Traveler at the End of Time

This chapter is a bit long, but shortening it would make the protagonist's training less important. It's so difficult! ! !

The protagonist's superpowers will finally be revealed bit by bit. For a native male protagonist who has no system and no rebirth, I don't know if any readers will like this kind of rhythm and golden fingers? Nowadays, there are system articles about time travel and rebirth everywhere. Maybe no one will read my article! ! ! !
