“The king then led his four armies and followed after it. Ahead of the golden wheel, there were four spirits guiding it, and the king stopped his horses where the wheel dwelled. At that point, the lesser kings of the east saw the great king arrive, and they came to the king with gold bowls holding silver barley and silver bowls holding gold barley. They present them to their chief, saying, ‘Welcome, great king! The lands in this eastern region are plentiful now. Please, noble king, rule them properly! We’ll serve you, right and left, and accept what you will.’
