Lin An, the most powerful emperor in the world, was a man who was afraid of getting into trouble. He hid in a second-rate sect and became the owner of the Transparent Valley, growing medicine and sleeping in peace. The whole family regarded him as a loser - until the heavenly calamity shattered the formation, he flicked a fruit and crushed it; until the stunning undercovers entered the back mountain, he saw that what was hidden in their bodies was actually the scattered soul of their lost loved one. When the great catastrophe of the world is approaching, the emperor is squatting on the ridge of the field, wondering whether the Ning Yuan grass will be enough to make tea tonight.
