Shi Qian opened her eyes and looked at the man’s handsome face.

“You have to be responsible to me.”

The thin lips of a certain black-bellied evildoer slightly hooked, with a smile that was not a smile.

From then on, there was an extra goblin in the house of Lord Zhan, the great demon king of the imperial capital! The big devil turned into a faint king and spoiled the little goblin to the sky!

Some people: “It’s useless except for that face, it’s just a vase! I’ll be dumped by Master Zhan sooner or later!”

Not long after… the legendary god turned out to be that little goblin!

Why does the boss of the hacker army look a bit like that little goblin!

The founder of the popular game on the Internet is more like that little goblin.

The woman who defeated the number one expert in the ancient martial arts is also a bit like… a boss! Kneel down!
