He makes trouble in the underworld, breaks into the city god, and walks through the fierce land three to five times. While cultivating, he also experiences. "Longevity Martial Arts: Starting from the Sit and Forget Technique": The protagonist traveled through the troubled times of martial arts and started from the Sit and Forget Technique. He cultivated his body and nature, prolonged his life, and finally became an invincible expert in the world. [The Dao of Fu Zhuan]: The book described the Dao of Fu Zhuan in the prosperous and chaotic times. The protagonist's calligraphy cultivated his body, his spells settled down, and he enjoyed a carefree life. I hope you like this fairy's recommendation. Muah ~😗
