Yang Dao and Dao Yin waited for the two people to come inside, and after a few seconds, two old men wearing robes came inside the room. They bowed their heads to the emperor on the bed and said, "Your lordship, we heard that two geniuses from the holy land have come to solve the trouble so we came here to pay respects." 

The emperor nodded and pointed at the two people and said, "These two are the geniuses in your mouth, Sir Yang and Madam Yin." 

The two men looked at the couple and they nodded, however, the minute flash in their eyes did not escape the two when they looked at Dao Yin. Yang Dao frowned and the old man in silver robes asked, "Sir Yang, have you found the source of the trouble?" 

Yang Dao ignored the old man and turned to face the emperor he asked, "May I ask who was the person responsible for laying out this palace?"
