I'm really not an expert in Douluo

Li Ruofan, who has always been steady, traveled to the Douluo Continent, without martial arts or spirit power. He was taught by the crappy system for three years and then left. Before leaving, he was given the ability to accept Tang San as a disciple and kill the scumbag Yu Xiaogang task. Tang San: "I would like to call my master the strongest, but he..." Passerby: "What's wrong with him?" Tang San: "He is really stubborn!" "I am obviously a mortal but there are many people." Respect Me" "Master is clearly invincible but too cautious"
