I Cast Eternal Life in the World of Mortals

In the boundless mortal world, I want to live forever, but I still want to live forever. Unexpectedly coming to this world where gods and ghosts are rampant, dragons and snakes rise from the land, Li Xiuyuan originally wanted to find a way to become an immortal, and even live forever. However, the earth's magic has collapsed and the heaven's magic is incomplete. Fortunately, there is a mysterious lotus pond that travels with him. Through experience in the world of mortals, he will evolve various magical powers. In the dream, the divine machine slays the dragon, the Rakshasa sea market manifests its true spirit, the clam demon holds pearls, the fox enchants people, the turbid dragon swims in the water, and the world is chaotic with demons. All kinds of disasters in this world are just because those who seek immortality seek immortality, and those who seek the Tao seek immortality. Dare I ask, is there a true immortal here? Can you live forever? Also known as "Longevity Is That Simple"
