(Flying Raijin Level Two + Dual Kamui + Rinnegan + Eight Gates and a whole bunch of other Naruto abilities) "Ding! The Host has just suffered a death like no human should. As the future emperor, how can you have such a humiliating history?" [Mission issued: Take revenge!] [Reward: Flying Raijin Level Two] [The gap in strength between the two parties is enormous. The reward can be claimed immediately.] One day, a powerful figure from a fantasy world finally discovered that a low-level cultivator had mastered spatial abilities. He stared at him, utterly baffled. The protagonist mainly uses Naruto abilities.
