Traveling Through Dou Si, I Became Lan Xuanyu?

My name is Mu Chen. I was just an ordinary person in my previous life. Until the moment I opened my eyes, I became the male protagonist of the fourth Douluo Dalu - Lan Xuanyu. But this time, I won't go the same way. What I awakened was not only twin martial souls, but also a god-level system that releases reward items at check-in locations! Qian Lei: "Boss knocked out the Soul Beast King with one punch. Isn't your martial soul Blue Silver Grass???" Liu Feng: "My martial spirit... It is kneeling to him!" Bai Xiuxiu: "As soon as he opened his mouth, I even voluntarily sacrificed my soul..." Soul master rules? Sorry, I am the rule! Since then, Muchen has become famous throughout the continent!
