Yuchi Xiu had already infiltrated the mine to gather information.
Su Xiaoxiao could actually sneak in, but there was no need.
She was the young master of the Cheng family, so she had to enter openly.
Actually, these people dared to bully Cheng Sang because she was crazy and easy to bully. They looked down on Xie Yunhe as a lived-in son-in-law. As for Cheng Lian, she was the daughter of a concubine and her status was lower than Cheng Sang.
After many years of hard work, although Xie Yunhe and Cheng Lian had subdued most of them, they did not use force.
Treating them like businessmen, they would give them more benefits and fatten them up. Their courage would also imperceptibly fatten up.
Later on, the Cheng family produced a Saintess. The people from the mine more or less gave Xie Yunhe and Cheng Sang some respect, but not much.
To put it bluntly, they were working together; it was not a master and subordinate relationship.
