An Unexpected Journey of Douluo

"My name is Xiao Yi. As a time traveler, you may not believe me when I tell you." "Have you seen the system twin?" "Have you ever seen the system play missing?" "Have you even seen the system come out and switch voice packages to rap in your head?" "Uh... Anyway, I saw it..." A pair of spiritual pupils, a six-color unicorn thorn, twin martial arts + system talent, and ninjutsu secrets. No apprenticeship, no love for the protagonist, a small group in the early stage, and a solo career in the middle and later stages, a semi-simple story.
