Knocking on the Heavenly Gate

Five hundred years ago, sect master Lu Chen ascended and knocked on the Heavenly Gate, only to discover that the Immortal Realm used a formation to plunder spiritual energy from the mortal world, severely injuring the immortals. Five hundred years later, he awakens from his grave with all his memories lost. Facing a crumbling sect burdened by debt with only one remaining disciple, he sets off with Meng Youkang on a journey to make money and restore the sect. By chance, he reunites with an old friend and infiltrates the Demon Heaven Palace, uncovering the conspiracy behind the fake Lu Chen inciting a war between righteous and demonic forces while draining the mortal world's spiritual energy for the Immortal Realm. An explosive and hilarious battle to knock on the Heavenly Gate begins.
