Douluo: Wuhun Fights Greymon!

Lin Yuzhong, a college student, burst into tears while watching the final evolution of Digimon in the cinema, and his vision went dark as he traveled through the world of Douluo. "Travel through the first year, there is no system." "Time travel to the second year, there is no golden finger." ..... Six years later, he still hadn't found his golden finger. With the help of the awakening master Su Yuntao, he awakened his martial soul. Rolling ball beast! Digital Soul! "The Rolling Ball Beast has not evolved. If you say this is a useless martial spirit, I won't find fault with you." "But now that it has evolved into BattleGreymon, what should you call it now? Huh?" "The separated martial soul is weak? Eat my digital soul!!" .... Rollermon→Agumon→Greymon→MechanicalGreymon→BattleGreymon→BattleGreymon Do you think I can only evolve this way? No, you are wrong, everything comes out of a rolling ball! The evolutionary path of Rollermon is much more than that!
