Calm After The Storm?

After destroying the two people You Xi Wang adjourned the meeting. He turned to his master and bowed. Then he was about to speak when Animo Albus spoke, "Xiao Wang, go visit your parents. We will take the leave first." as she said that she had already stood up. You Zhichi came over to see off her master.  Alester Book gave You Xi Wang a reassuring smile and also followed his martial sister along with Achilles. 

You Zhichi spoke to her brother in a gentle voice, "Go change your clothes, we will leave soon. Also, wash your hands before you go out lest the kids get sacred." You Xi Wang's hands were still covered in blood. The boy nodded and condensed a ball of water around each hand. The blood on his hands dissolved in the water turning it red. Then he used fire attributed spiritual energy in his hands and evaporated the water ball. 

He turned to You Zhichi and asked, "Do you think it was okay to let them off like this?"
