Coming soon _(:з"∠)_
Happy ending
Yun Si transmigrated into a book as the sect ancestor of the protagonist's little villainous cannon-fodder character. After learning how the story was supposed to go, he tried to kill the protagonist, Xun Yi, but failed.
His rebellious streak kicked in, and he decided to go with the flow and raise the boy properly. With his abilities, surely he couldn't end up dying at the hands of a wolf cub he'd raised himself.
But he never imagined that the protagonist, Xun Yi, had been reborn.
And then Yun Si died. "..." That really stung.
Yun Si transmigrated back to the moment he first entered the book. But now the protagonist was innocent and sweet, his eyes full of affection and admiration.
Yun Si: "Heh." He wouldn't trust that wolf cub again.
Xun Yi: "Meow meow meow???"
I finally understand why you dig new holes ∠( ? ∠)_
