Modern youth Lin Xiao transmigrates to the cultivation world. Because of zero aptitude, he is abducted into the Demonic Sword Sect and reduced to a grave-keeping miscellaneous servant at the Burning Heaven Sword Tomb. The sword tomb's sword Qi is treacherous, but he unexpectedly awakens full comprehension. The Qi Nourishing Technique instantly reaches completion, absorbing sword Qi to break through rapidly. Upon touching a sword, he comprehends the predecessors' sword techniques, and upon seeing alchemy once, he masters it. All the way, he plays the pig to eat the tiger. The outer sect test startles the twin elders into fighting for a disciple, the heavenly ladder summit subdues the righteous path, the infinite ruins swallow sword spirits and gain the divine sword's acknowledgment, finally condensing ninety percent sword intent, publicly beheading the Great Wei crown prince, and making ten thousand swords bow to the sect master. From the humblest grave-keeping miscellaneous servant, he counter-attacks to become the world's sword emperor, declaring that starting today, he will no longer be a grave keeper.
