I Became the Lord of All Demons by Cheating

The human monks are in retreat every day, the demons are busy conducting KPI assessments, the fairy world is conducting professional title evaluations, and the monsters are scattered, fighting on their own, in a chain of contempt. Huang Xiaojiu accidentally rescued an old scholar from the human race who was in dire straits, but the man did not repay him and gave him a copy of "Strategy for the Founding of the Nation of Ten Thousand Monsters" written by himself. This book was regarded as a joke among the human race, but Huang Xiaojiu found it like a treasure.
