A level-60 veteran player from Teyvat's launch, Feng Yule, transmigrated into Demon Slayer.
He was ready to make his mark!! The three little ones! Nezuko! The Hashira! There wasn't a problem a Teyvat Fried Egg couldn't solve.
The dim room was filled with the scent of medicine.
"You quack! Die!" A sickly, emaciated boy stood behind him, gripping a hatchet menacingly.
Kids, looks like I arrived a little too early.
The good news was that he could still open his Teyvat status screen.
The bad news was that the mission was called "Chapter of Birth: The Demon King's Reformation."
Worst of all, he had transmigrated as the doctor who created the Demon King.
Feng Yule: Trying to drag the scumbag boss out into the sunshine.
"Newbie Mission Reward: 16,000 Primogems."
But then again, Feng Yule caught a blade with his bare hands and shoved a book titled How to Be a Decent Person back into the young Demon King's hands.
Muzan: ? Are you trying to teach me how to live???

"You haven't been killed yet?" Feng Yule asked one day, dozing in a tree.
A lump of flesh writhed in the depths of a hollow tree, screaming, "It's all your fault for teaching that terrifying Yoriichi! What's this Elemental Sight nonsense? What's this Breathing Style based on Elemental Reactions nonsense?!!! I never even provoked him!! Why does he keep haunting meeeeeeeeeeeee, "
Seeing a red figure speeding toward them like lightning, Feng Yule immediately pointed.
"He's over there."

One full-moon night, the Moon Hashira finished slaying the demon assigned to him and turned to leave. A white figure flashed around the corner.
"Moon Breathing..." Yoriichi's twin, Michikatsu, instinctively started to swing his sword.
The white-clad [girl] was barefoot, stepping through the moonlight with her eyes closed. The wing ornaments behind her head trembled as she tilted her head, as if only just noticing him. "...Hm?"
Michikatsu later: Moon Reactions. Pretty amazing, right?
*
The long-awaited Blue Spider Lily was right before him! Muzan immediately reached out to touch it.
The flower actually spoke: "Who wants the Blue Spider Lily? Who wants it?"
Muzan raised his hand. "I do!"
The flower suddenly turned into the face of the subordinate and nemesis he hated most, making a pose of "lofty moral approval."
Muzan: "Get lost aaaaaaaaaah!"
