Daming: I, the Fortune Teller, Was Forcibly Hired by the Empress at the Beginning

The little warlock lived on the street and almost starved to death. He casually made a divination for the empress, and it was calculated that she would suffer a bloody disaster within three days. The empress drew her sword: "I was right to make you the Imperial Master, but I was wrong to kill everyone in my family!" Three days later, enemy assassins attacked the palace at night... I backhanded an amulet and directly changed the world.
