Demonic Cultivation's Undercover Agent: Seven Hundred Years of Sign-Ins at the Immortal Sect

Li Ya transmigrates to a fantasy world where immortals and demons stand opposed, becoming a demonic spy embedded in an immortal sect.

Life as a double agent keeps Li Ya on edge, constantly anxious and uneasy.

Signing in at the woodshed on Cloudstream Peak grants him the Haotian True Scripture.

Signing in at the immortal sect's martial arts arena grants him the Sword Art: Sword Opens Heaven's Gate.
