My Little Sister Is Exceptionally Good at Causing Trouble

Dangerous and uncanny sealed artifacts, domineering superpowered individuals, bloodthirsty and brutal cultists, and the maddened, twisted gods of old.

Pay a price, receive a blessing.

Welcome to this dangerous, all-too-real world.

But what does any of that matter? Mo Yu is just an utterly ordinary transmigrator with a younger sister, a house, dead parents, and a cheat System.

And his little sister is super sweet and adorable.

“Mhm, big brother is the best!”

As Mo Yue clings to her brother's sleeve and acts cute, she builds up her power, expands her organization, and recruits the supernatural.

Mo Yue: I may run a secret society, consort with underground organizations, make ruthless decisions, and rule with an iron fist, but I know I'm a sweet, adorable, obedient, and sensible good girl!

At least, I am in front of my brother.

Before Chapter 72, the protagonist is rather passive. After Chapter 72, his personality undergoes a change.
