The Demon Realm's Beloved Child Enters the Immortal Realm

Youyou is the youngest daughter of the Demon God, the little princess adored by all in the Demon Realm. But recently, the Demon Lord had a huge argument with the Immortal Realm's Emperor. The Demon God is in a foul mood, spending all day smashing pots and bowls and throwing tantrums in his cave.

Youyou wants to ease her father's worries, so while the Demon God is in seclusion, she sneaks into the Immortal Realm.

When the Demon God emerges from seclusion, he can't find his adorable daughter and is frantic with worry. Just then, a message arrives from Youyou. Her childish voice confidently tells him:

[Dad, I've infiltrated the heart of the Immortal Realm! Get ready, and when the time comes, we'll coordinate from the inside and out!]

Looking at the little dumpling that is Youyou, the Demon God is moved to tears. "My sweet girl, you've grown up. Don't worry, Dad will await your command. Stay safe."

One year passes.

Two years pass.

Many years pass...

At last, the Demon God receives another message from Youyou. "Dad, turns out the Young Emperor saw through me ages ago. He said I can either marry him or die. I don't think I'll be able to come home QAQ"

I'll revise the title and blurb, okay? I'll make adjustments before I start posting.
