Longming Empire

This is a savage, disorderly and dark world, where there is sufficient aura and many ethnic groups. White-skinned magicians, yellow-skinned magicians, armored knights and long-sword samurai all exist. Under the lie of freedom, there is only constant killing in this world, and people from tribal rule and churches hunt heretics to the extreme... And you, as a time traveler, as the only person with true wisdom, can you save this world?
