The Invincible Overlord of Douluo

Li Xin traveled from the earth in the 22nd century to the Holy Soul Village in Douluo Continent and became brothers with Tang San. At the beginning, an unknown martial soul was awakened. With full innate soul power, he was already invincible without any training, because he had a system! See how Li Xin makes friends and betrays, fights against Sadira, wins the pinnacle battle, breaks through the universe of all realms, and becomes invincible in the Ultimate Universe! (The protagonist of this book is invincible, has a system, and has plug-ins, but there will be major changes based on the original work. Except for CP, the author does not know the power system of Douluo Continent and can only write blindly based on his own ideas. Please forgive me!!!)
