[Under One Person + Gender Change + Fireworks (The Ultimate Venomous Fun Person) + Extreme Joy + No CP]

Just because of seven consecutive fireworks, Luo Yun was sent directly to the world of "under one man" by the God of Fun Aha. He changed from a 185cm male college student with abdominal muscles to a 145cm little loli who looked like Fireworks. He was also bound to the Chosen Fun Person System. As long as he played the role of Fireworks and gained pleasure, he could unlock new abilities and continuously improve his strength.

Zhang Chulan: "Hua Huo, you are not a human! Give me back Pella!"

Xia He: "Damn it! Why is Hua Huo prettier than me?"

Wang Ye: "This girl is really good at playing games. She even deceived herself!"

…

Playing Hanabi? No! From now on, I am Hanabi!

What is joy? I am joy!

Ahahahahahahahaha!

Garp, why are you chasing me every day? Huh? Where's Great Britain? Can't you find it yourselves? Inviting me to join the navy? Me, the King of Great Britain, are you kidding me? No way!

Redheads? Giving you face? Not getting involved in the summit? Giving a cripple the run for his money! Asking for a beating!

Huh? I'm not that Black Hairless guy! What does your looking for Black Hairless guy have to do with my Gundam? You've got the wrong person!

[Knowing joy is the unique right of intelligent creatures, and the joy system encourages the host to enjoy the joy of life! 】

With his many years of experience in reading novels, as long as the protagonist awakens the system, he will get a happy time like a dream...

Now, it is finally his turn to enjoy it.

Breaking the dimensional wall, facing the two-dimensional beautiful girls that he dared not dream of before, Chen Ming decided to give them a warm home...
