Are there any novels recommended where the main character transmigrated to another world and established a gang or power?

I recommend the following two novels to you. The first one is One Piece: King of the Beasts. The main character's soul travels through Kaido and exploits his territory in the world of pirates, expanding his power, conquering the world, and establishing his own power. The second book was "He Comes from the Great Tang, the Fierce Mountain Thief". When the main character transmigrated to the prosperous era of the Great Tang, he had to become a mountain bandit who gathered in the mountains and forests. Through smuggling, he raised money, stored food, and divided the various mountain peaks to gradually become stronger. He then spread his influence deep into Liaodong and subdued the Khitan and Bohai tribes. When the entire Great Tang was in the midst of the An Lushan Rebellion, the main character brazenly attacked... I hope you like my recommendation, Mwah ~😗
