Five hundred years ago, Lin Xuanzhen, the youngest mighty expert in the Tribulation Transcendence stage in the cultivation world, sought a breakthrough and was reduced to ashes beneath the ninth heavenly tribulation. When he opened his eyes again, he had reborn in the body of a down-and-out university student with the same name in the twenty-first century. The spiritual energy of heaven and earth is now scarce, ancient martial arts families live in seclusion, and the legacy of cultivation has been lost. But the protagonist discovers that this city hides a mystery: a business tycoon is actually a Golden Core cultivator, a demonic cultivator is kept in an underground fight club, and even the campus beauty sitting beside him possesses a rare Profound Yin constitution unseen for a thousand years. In the shattered pocket dimension he carries with him lies the unfinished "Eternal Longevity Art" from his previous life. This time, he'll use the city as his furnace and the mortal world as his fire to forge an indestructible Dao heart!
