After Time Travel, What Kind of Immortality Can I Cultivate? Do G

Traveling to the world of cultivating immortals, others are refining Qi to build the foundation pill Yuanying. I discovered that my bones were made of blued steel—the same material as the door in the sky. That door was a machine that had been running for three thousand years, with crooked welds, missing teeth in the gears, and overloaded drive shafts. The first three "Ascended Ones" were all burned to death inside. I am the eighth. The entire world of immortality is waiting for someone to walk in, calling it ascension and glory. I held a wrench and called it high-risk equipment, with a deadline for rectification. But what's even more troublesome is that the door is about to collapse. And the entire world of immortality is at my feet.
