In the Age of Martial Arts, I Awaken an Immortal Dao Guardian Spirit

This is a world teeming with ferocious beasts, where mythical and primordial creatures are constantly awakening and running rampant. Heaven and earth have changed, and with the spiritual qi revival, countless monsters and demons keep emerging, making life unbearable for humanity. Fortunately, humans have secret arts that let them hunt guardian spirits and make them their own, growing stronger so they can resist a world transformed by the spiritual qi revival. Xiao Yun wakes up reborn twenty years in the past, carrying the memories of his previous life. He is the first to hunt an against-all-odds SSSSS-rank guardian spirit: the Book of Life and Death! From then on, he unlocks unlimited guardian spirit access and awakens hundreds of millions of guardian spirits. In this world of spiritual qi revival, he slays any god or Buddha who stands in his way! Buddha Tathagata (Sacred SSSSS rank): Enter my Buddhist sect, and no spell can harm you! The Grandmaster of Heaven (Sacred SSSSSS rank): Enter my Biyou Palace and explore the mysteries of the Dao! The Heavenly Dao Hongjun (Sacred SSSSSSSSSS rank): Enter my Zixiao Palace and cultivate the Three Thousand Great Daos!
