(Probably no single heroine or no heroine at all. The protagonist is invincible and the fights are satisfying. As for power scaling, let's just say I'll do my best to keep it from going off the rails.)
Chu Kong transmigrated to another world, Blue Star, and his strength grew day by day. At first, he thought he was following the spiritual qi revival script.
But what was this merging of myriad realms? And why was there a main god's space? No, this place was called the Fusion Space.
Fortunately, he awakened the unique, top-tier talent: Game Mode. While others awakened talents during the spiritual qi revival and struggled through cultivation, all he had to do was fight monsters, level up, complete quests, and get loot. He could even draw items and skills from games.
His first game turned out to be League of Legends, his favorite game from his previous life. He immediately drew Heartsteel, which could stack endlessly to boost his constitution, as well as Guardian Angel, the resurrection armor. With a 300-second cooldown, how was anyone else supposed to compete? Now he had both the stats and the mechanics.
As he visited more worlds and met more and more geniuses, Chu Kong could only say:
"How come your talents are so damn devious too?"
Everyone replied, "We're still nothing compared to you."
