A Prison Guard in the Cold Palace: After Ten Years of Sign-Ins, I Become Unrivaled

In the Great Yan Dynasty, demons run rampant, and martial arts reign supreme.

Yang Han transmigrates into this world and becomes a lowly guard in the Cold Palace, a man whose life is worth less than a blade of grass.

In this place, so steeped in dark energy that even dogs refuse to stay for a full day, Yang Han awakens an Invincible Sign-in System.

“Ding! Sign-in successful. Reward: Tendon-Transformation Scripture, mastered to perfection!”

“Ding! Sign-in successful. Reward: Indestructible Diamond Body!”

Just as Yang Han plans to quietly grow invincible in the Cold Palace, he discovers that every disgraced consort banished there is more than she seems.

The gentle and amiable Consort Xiao is the reincarnation of an ancient Ice Emperor, while the bewitching and alluring Consort Lan is a former Holy Maiden of the Demon Cult.

They all carry heavenly punishment and demonic energy within them, and only Yang Han’s divine art can “warm them up” and keep them alive.

Before long, the peerless female emperors who once stood high above everyone else, arrogant and untouchable, are looking at Yang Han with unmistakable longing.

Ten years later, a demonic calamity descends. A terrifying army of demons breaches the imperial capital, plunging the entire court into despair.

Just as humanity is on the verge of total annihilation, a sword aura capable of shattering the stars suddenly erupts from deep within the Cold Palace.

“What demon dares disturb my cultivation?”

Everyone is stunned, and the gods and Buddhas in the heavens are shocked. The peerless powerhouse, invincible in this age, had been hiding in the Cold Palace all along!
