Quick Transmigration: Who Says the Second Male Lead Is Gentle and Kind?

Two male leads

After Nanshan was attacked by the immortal sects and fell off a cliff, his soul shattered. A little gray puffball claiming to be a "System" captured the fragments of his soul, bound itself to him, and sent him to transmigrate through various small worlds to fix their timelines. With each timeline he repairs, Nanshan receives a gift from the Heavenly Dao, restoring his soul and power.

Nanshan: Why do you look so familiar to me?

Some Chuan: What are you talking about? I have no idea!

Little Gray: Hello, the person you are calling has disconnected.

Nanshan: ^_^
