Ancient aristocratic families monopolized the Tianyan Immortal Grass, and the common people lived as grass slaves - this is the "Law of Immortal Grass" carved into the bone marrow. Shen Yi awakened the dual talents of forming formations to control Gu. The poisons he raised bankrupted the mother nest, and the formations he made made Cthulhu perform a square dance! From sneaking into an aristocratic family to break up the situation to beating up the CEO of the Brood, he relied on the "sand sculpture system" and "rice bucket Gu" to find a counterattack path of "freedom of fairy grass" in the world of immortal cultivators: "Who said that the Gu master can't grow fairy grass? I want the Brood to work for me!"
