Gu Changsheng was sent to the ancestral mausoleum and became the most inconspicuous tomb-keeper disciple of Taiyi Sword Sect. Outsiders just thought that his way forward was cut off, and the sect just threw him into the back mountain to wait for death, but no one knew that the Guixu Mausoleum Realm was not a place of death, but a forbidden ancestral mausoleum that was still in operation. Swords rang out in the middle of the night, ruined monuments hid their meanings, tomb lamps spontaneously ignited, and secrets that had been sealed for centuries were awakened one after another. Since he stepped into the ancestral mausoleum, he can inherit the inheritance by repairing the broken stele, inheriting the traces of the Taoism by guarding the ancient tomb, and cultivating the invincible sword power by suppressing the weird. When foreign enemies were knocking on the mountain and the sect was about to fall, the world discovered that the man who silently guarded the tomb in the ancestral mausoleum had already become the real trump card of the Taiyi Sword Sect.
