My Otherworldly Little Sister Is Unbeatable!

My name is Ling Dong, and I'm a traveler!

I can travel between countless worlds, though I don't have much control over it.

I have a "Be My Little Sister" System, though it's not very reliable.

And I have a father, Ling Tianjiao, whose strength defies the heavens, though he barely exists.

I've visited many worlds. Some let you cultivate immortality, some are electronic worlds, and others are broken beyond repair.

There are also a few little sisters in the worlds I've traveled to. Since the System upgraded, I've been able to bring them back to Blue Star.

But I don't think they need me to go looking for them.

They're just too invincible!

It feels like it won't be long before they break through the void with their martial power and come find me themselves!

With little sisters this invincible, what could spiritual qi revival do to me? Even if the supernatural came back, what could it do?
