- Description from Novelupdates

Shen Ran transmigrates to a fantasy world and becomes a disciple of the Empyrean Sword Sect. Problem is, everything about him is ordinary— ordinary talent, ordinary temperament, ordinary life… In this cruel world where cultivation talent determines how far one could go, this means that Shen Ran’s future can be seen at a glance. Banished to the servant quarters as a servant disciple, his daily grind is to attend to mundane chores which will go on until he dies of old age a hundred years later.

Then he comes across a narrative modification system which makes it possible to rewrite entire lives! An avid reader of online novels in his previous life, Shen Ran relishes the chance to read the narratives of everyone and everything and alter them. The narratives modified by him will become reality!

This is the story of how he transforms his ordinary life by editing his narrative and going on to cultivate the Dao, handle calamities, and rule the ages. And he is limited only by his imagination!

I didn’t know this was a world inside a game. And I didn’t know my master was a mid-boss. “No way… wasn’t she supposed to self-destruct because of her personality?!” …I’m sorry.

Our protagonist Caam is a man from Earth that was reincarnated into this world as a demon. In order to survive, he spared no effort in avoiding the sparks of battle and without noticing it, he became strong himself.
