Literary version: A long dream, then back to youth. Twins rush in to save the day and rekindle their parents' romance.
In plain terms: Ling Ao, son of the head of the Lingyun Sect, is gifted, but no one knows who his father is. No one dares ask, and he doesn't ask either. He spends every day studying and cultivating, earning the title of Little Martial Uncle of Lingyun.
Si Yi, son of the Demon Lord of the Demon Realm, is mischievous and troublesome. No one knows who his mother is, so he went and asked. He got beaten several times for his trouble, but never gave up, and kept causing trouble everywhere.
The Demon Realm's divine artifact, the Heart-Calling Bell, was said to let its user know the past and future. So the little prince quietly snuck away with it, only to discover it was unfinished. With no other choice, he fled to the cultivation world and ran into Lingyun's Little Martial Uncle. The two hit it off at once, getting along famously and lamenting that they had not met sooner. Their pursuers were close behind when the bell suddenly activated, dragging them both into the past, a thousand years earlier, and setting them on a journey to find their parents.
"That lively, sly junior sister is just like Mother used to be. Was Mother really like this back then?" the Little Martial Uncle murmured.
"That sword cultivator pretending to be a cultivator is Father from back then! Hahaha, so Father always just went straight to violence!" the little prince laughed.
Then who exactly were their father and mother?
The Little Martial Uncle secretly snatched the confession letter meant for his mother. He opened it and saw a bold, forceful hand: "My heart belongs to you."
The little prince leaned in, laughing as he read. "This handwriting looks exactly like my dad's... Ha... Wait, what the hell!"
