Traveling Through the Qi Absorption Era, I Became an Outdated Foundation Builder

He Sheng transmigrated into the cultivation world believing he had struck the ultimate jackpot. He awakened with superior-grade dual spiritual roots in water and earth, possessed mid-stage Foundation Establishment cultivation, and even served as the patriarch of a prominent cultivation family. However, he quickly realized that something was terribly wrong. The cultivation world was undergoing a massive paradigm shift in its orthodox teachings; the traditional mortal-style Qi Refining methods had been relegated to obscurity, while the mystical Qi Absorption path was rapidly ascending to dominance. Unfortunately, this made him an outdated cultivator who was effortlessly crushed by the rising geniuses of the new era. Fortunately, He Sheng possesses the Hourglass of Regression, a unique treasure that allows him to revert his cultivated techniques without any loss. This ability not only enables him to accumulate universal cultivation time but also permits rapid simulation of various training methods, granting him infinite potential for growth. Armed with this extraordinary advantage, He Sheng embarks on an unprecedented journey to redefine his destiny and carve out a brand-new path to immortality in a world that has already moved past him.
