The general trend of the world is that if it stays together for a long time, it must divide, and if it stays apart for a long time, it must unite. Mao'er, a senior agent of the Special Intelligence Division, once traveled through time, making the originally chaotic and complicated situation in Lanchuan even more confusing. The passing geese leave traces, and the passing people leave their names. Now that I'm here, I can't remain unknown. I want the whole world to know that I, Ji Ling'er from the Special Intelligence Department, is here! Since heaven and earth are unkind, I will stir up a bloody storm and change the situation!
