I'm Looking for the Magic Thought of Immortality

In the world of Qingming, corpses are transformed into immortals, spirits seek for immortality, ghosts and demons get married, and inner demons breed in the cave. Dragons appear, and the Supreme annexes the eight wastelands. Gluttony is rampant and murderous stars sweep across the world. The young man strayed into the depths of Taoyuan, where the dusty world was born. The road to immortality was bumpy, but his heart was like waves, but the green mountains remained the same.
