Such a sudden intervention was unexpected by anyone.
After all, most people present were there for Jiang Xiaobai, and the black mist figure's background was unclear, but everyone instinctively thought it was also there to deal with Jiang Xiaobai.
With absolutely no preparation, the sudden action from the other side was a loud slap in the face to everyone!
The Demon Lord and Liu both looked over, only to see the black mist figure slowly rise into the air, sneering coldly at the still-open prismatic space portal not far away.
"All of you, get back to where you came from. Dare to be impudent again, and I will destroy you!"
Only then did the Demon Lord realize that there was a powerful being behind that portal, spying on this place!
As soon as the black mist figure finished speaking, the portal vanished, the aura fleeing and disappearing.
The scene froze instantly!
Su Mei and others looked towards this place, completely baffled!
