A continuation from where High School DxD Volume 25 left off.

After his soul transmigrated into the world of Teyvat, Luo Qing was selected to become the new Trainee Fatui Harbinger, and he was about to be sent to Liyue on a diplomatic mission (to cause chaos). To his surprise, he awakened a “Frustration Value Collection System” — as long as he frustrated others, he could collect frustration points, which he could use to participate in a lottery.As he stared at the list of items in the lottery interface, Luo Qing fell deep in thought:“Spirit Speech: Time Zero,” “Multi-Shadow Clone Technique,” “Thunder Breathing Style,” “Golden Experience Requiem,” “Railgun,” “Gomu Gomu no Mi...”Why on earth were these things appearing in the world of Teyvat?!Given the notorious reputation of a Harbinger, Luo Qing knew that if he didn’t grow strong, he was certainly doomed to a miserable end. Thus, his style became... increasingly abstract...---Years later, to prevent the infamous Fatui Harbinger, Luo Qing, from causing havoc everywhere, the people and political leaders of the Seven Nations united to issue a formal protest to Snezhnaya.In response, the Fatui in Snezhnaya issued an official statement:“This Harbinger is only a trainee. He has been dismissed.”
