Lin Mo has been able to see dark shadows and evil spirits that ordinary people cannot detect since he was a child, but his family thought he was suffering from schizophrenia and was forcibly sent to Qingshan Mental Hospital.
He originally thought that his life would collapse, but he unexpectedly discovered that everything in this hospital was strange - the old Taoist priest who was madly chanting "The alchemy furnace exploded", the amnesiac woman who was holding a broken knife in a daze, the irritable old man who was constantly swearing... These seemingly crazy patients were all hidden ancient god-killing bosses.
What is even more shocking is that the kind-hearted old dean has lived for thousands of years and is the last leader of the ancient God-Slaying Alliance. And there was only one reason why he targeted Lin Mo -
"You kid, you are born to be a god-killer, you are truly a peerless fairy!"
From then on, Lin Mo cooperated with the medical staff for "treatment" during the day, and at night he learned alchemy, formations, and god-killing sword techniques from various crazy bosses. In the mental hospital, he embarked on an outrageous and passionate road of killing gods and cultivating immortals.
When the evil god revives and catastrophe strikes, this young man who was once regarded as a "madman" will eventually hold the God-killing Sword and become the last line of defense to protect the world.
