In the middle of the night, the two men quietly left the city with two Black Iron Camp guards and went straight to the suburbs where the refugees were living. The so-called refugee house was actually only a few shacks outside the city to accommodate the refugees. The summer was hot, it would not be cold even if they were to stay in the open air. A group of officers and soldiers guarding the city nearby watched to keep them from making trouble, there were several big pots near the side of the street. It must have been where the people usually received their porridge and rations.

In the middle of the night, the refugee house was quiet, the guards of the Black Iron Camp took the lead in sneaking in. Their footsteps were so light that even the stray cat sleeping beneath a tree was not disturbed.

Xu Ling whispered, "Your Highness, something isn't right. There are usually signs in places where an epidemic occurs, and medicinal water would be sprinkled on the ground. It shouldn't be so quiet."

Chang Geng remained unchanged: "Since Yang Rong Gui knows we are here, he will not be unprepared. Wait and see."

When he finished, the Black Iron Camp guard who had just entered slipped out like a black shadow: "Your Highness, there are only thirty people living in this refugee house, mostly young and middle-aged men and women. There is no sign of the outbreak of an epidemic."

"There are a hundred thousand refugees in Jiangbei, but only thirty people are in the refugee houses outside Yangzhou City?" Xu Ling sneered. "Yang Rong Gui truly underestimated people too much. Are the people living inside also good at talking, well fed, warmly dressed and carefree? I think most of them are fake refugees that were hired to be here."

The guard asked, "What can we do, Your Highness?"

"Being completely unfamiliar with one's surroundings is not the way," Chang Geng whispered. "First, try to contact Master Liao Ran and let the brothers make a few turns in the vicinity these two days to see if there are any traces. There is no impervious wall in the world. I don't believe Yang Rong Gui can cover the sky with one hand."

That evening, a fast horse left Yangzhou City and went north towards the capital with a secret letter, informing those ambitious people that Yan Wang had fallen into the trap.

At the same time, the local city defense officers and soldiers in Jiangbei received dispatch orders from the governor of Liangjiang overnight. They came in casual clothes and secretly increased their troops to the Yangzhou Prefecture. The whole Yangzhou Prefecture was still singing and dancing, but it already became loose on the inside, tightened on the outside.
