The Tough Guy System

"I'm arrogant, I'm domineering, I'm helping the old lady cross the road!" "I'm despicable, I'm shameless, I'm a kind little angel!" "My name is Lu Yang, proudly." The funny young man was reborn and got a system full of loopholes. In order to save the dog's life, he got married and spread positive energy everywhere in a continent where strong people gathered. When I met an expert, I would be reasonable, and when I met a loser, I would be very cunning. By relying on deception and caution, I finally became a man who managed to finish the whole book. (Note: This book is slow to pick up, with the main character being a thief, a single female protagonist, and many supporting characters)
