Signing In with the Saintess: The Chaotic Godfiend Physique

[An outrageously powerful background + no groveling + steamrolling all the way + 1VN]

Gu Xiao transmigrates as the young master of the Heavenly Demon Hall.

His family background is mighty, and he can have anything he wants.

The only drawback is that he was born with a useless body, leaving him with practically no chance of cultivating immortality.

But his father, Gu Tianba, is a shamelessly doting father.

He spoils his son without restraint. Gu Xiao casually remarks that the Holy Maiden of the Joyous Union Sect is beautiful, and the next day she's stripped of her cultivation, cleaned up, and tossed onto his bed.

Gu Xiao looks at the beauty on the bed, but can't do anything about it.

Luckily, his System awakens!

His first System sign-in location turns out to be the Holy Maiden of the Joyous Union Sect.

Gu Xiao: System, are you even a proper System?

Signing in on Luo Qingli, Gu Xiao obtains the [Chaos Divine Demon Physique] and [Nine Transformations of the Divine Demon].

Gu Xiao, who'd been useless for eighteen years, smiles.

From then on, he embarks on the villain's path of forced sign-ins, never to return.

Sign in on Ji Ziyue, and he gets the [Primordial Yin Source].

Sign in on the corpse of the Child of Destiny, and he gets the [Unbeatable Sword Heart].

Sign in at an ancient ruin, and he gets the [Transformation of Space-Time and the Divine Demon].

He only wants to sign in quietly, but everyone starts wildly reading into everything.

The Holy Maiden: "He pretended to be useless for eighteen years? What a deep schemer!"

The Holy Son: "I spent my whole life working, only to hand it all over to him!"

The richest man: "How did my business empire become his private treasury?"

The Reborn One: "I knew it! He's the source of all evil in the future!"

Gu Xiao sighs, puts away the Heavenly Dao Origin he just obtained from a sign-in, and spreads his hands helplessly.

"I said I didn't do it on purpose. Do you believe me?"
