Somewhere in Yun'an City, in a mansion that had been renovated since last year…
The courtyard of the luxurious mansion was full of bricks, stones, soil, and wood. A few carpenters were knocking on pillars. Because the surroundings were full of rich and powerful families, bamboo fences had been specially erected on the courtyard wall to block the view and prevent the messy scene from attracting criticism from the neighbors.
Cao Aning, dressed as an ordinary servant, entered the residence with a lunch box in his hand. Behind him was Xu Bailin and the white-robed old man walking with his hands behind his back.
Cao Aning glanced at the back of the mansion. After confirming that there was nothing unusual, he went to a half-rebuilt house, opened the floor covered by wooden boards, went down the wooden stairs, and arrived at an underground passage.
