Good little Miaomiao had no intention of running off to find Joker on her own.
Honestly, even if she wanted to go alone, she wouldn't know the way. She didn't even know where Joker was right now.
Besides, even if she did go, she wouldn't just rush in. The Elders had taught her, "Know yourself and know your enemy, and you will win every battle."
Miaomiao wasn't stupid.
Anyone who could make an entire city tremble at the mention of his name had to be exceptional in some other way, even if he wasn't particularly strong in a fight. Miaomiao was confident in her own strength, but she didn't think she was truly invincible. Underestimating an enemy was the last thing she should do.
