I Really Don't Want Yo Burn Humanity

In Rome, as a noble, I once engaged in verbal battles with the Senate! In Britain, I fought Germans alongside the Knight King! In the Tang Dynasty, I simply wiped out the aristocratic families and became emperor myself! In Greece, as a human, I danced with the gods on Mount Olympus! ...And now, in the Qin Dynasty, I serve as the Imperial Preceptor, assisting the First Emperor and ensuring the eternal reign of the Qin Dynasty. As a time traveler, I've reached the pinnacle! Unexpectedly, the Chaldeans accuse me of creating singularities and destroying human principles! Facing Gudako and the Chaldean Heroic Spirits, veteran time traveler Le Ang expresses his pity. "Listen, I never intended to destroy human principles!" The Chaldeans respond: "Do you think we'll believe your lies?!" PS: There are some secondary settings for plot reasons, so please don't get too hung up on them.
