The next morning, Sam, along with other candidates and Watt are assembled at the Duke's mansion.
That day, the Duke looked at Sam in a completely different light. At first, he was worried about Sam only on the condition that he would use the whatever future influence he would get and take revenge on them.
But the yesterday's fireworks are something that gave him a new understanding. He doesn't know how Sam did this, but the threat was real and even doesn't have enough confidence if he was caught up in that spiritual energy explosion.
He visited the Van family estate which was almost completely destroyed and saw that the spiritual energy was in a complete turmoil. An acolyte would die just entering the place.
He was in a complete astonishment and when he heard about the letter from the General, he couldn't help but think back to the situations and recall if he had offended Sam in anyway.
