Everyone in the world knew how terrifying smallpox was. As long as the commoners had it, they could only trap all the patients and burn the source of this illness.
The Crown Prince cherished his life. He wanted to disturb the morale of the army, but he did not want to be exposed to danger. If he let this group of sickly people with smallpox live, wouldn't it be dangerous for him too?
Hence, he said, "Smallpox is not a small matter. No one knows when or under what circumstances it will be passed on to others. If we're not careful, it will become a catastrophe that will cause the entire city to fall. The soldiers should know that they can't harm more innocent people just to make an exception for a few people."
"Pass down the order. Everyone in this hut will be…" killed without mercy!
