What?! You Were Sent to Infiltrate Them, but You Signed In and Became the Demon Ancestor

[The rating has just been released and will rise later.]

On his master’s orders, Gu Qingfeng infiltrated the Heavenly Demon Cult and became an honored undercover agent for the righteous path.

Before he left, his master repeatedly warned him: Keep your identity hidden, keep a low profile, and never draw attention.

But the moment he arrived at the Demon Cult’s mountain gate, he awakened a dual-polarity sign-in System and obtained the Supreme Demon Bones. Supreme demonic energy soared into the sky, and all demons bowed before him. The entire Demon Cult immediately declared him the reincarnation of the legendary Demon Ancestor!

From then on, Gu Qingfeng’s life as an undercover agent spiraled completely out of control.

He tried to hide his strength, but one punch leveled a hill;

He tried to weaken the Demon Cult, but his reforms made the entire sect vastly stronger;

He tried to let his fellow righteous cultivators escape, but they praised him for playing the long game to catch bigger fish;

He tried to stop a war between the two sides, but both the righteous and demonic factions were convinced he was plotting some earth-shattering scheme.

Years later, Gu Qingfeng looked at the demonic giants kneeling throughout the great hall, then at the top-secret mission sent by the righteous path, and fell into deep thought.

“Master, I only came here to go undercover.”

“But they insist on making me their sect leader!”

When the abyss split open and the Immortal Ruins descended, both the righteous and demonic factions finally realized that Gu Qingfeng, whom they had regarded as a peerless demon and a hidden agent of the righteous path, had long since become the final line of defense against the calamity threatening all the heavens.

The Mortal Realm, Soul Realm, and Immortal Realm: this world was far more complicated than it seemed.
