Tang Shunian nearly fainted when he heard Jing Yiran's words!
He had been very proud of this underground kingdom, which Jing Yiran was referring to as "rat hole"!
Normally, people could not break through this place, and his underground passages and cellars had been built by ten designers put together. Further changes had been added by him after the construction, in case they leaked the secret designs.
As for the layout of underground passage, only he knew about it and there was no paper version stored anywhere. He had remembered all the paths inside his head and burnt every copy of the design.
But Jing Yiran came in here so easily!
It impacted Tang Shunian's confidence tremendously!
He had thought that Jing Yichen was not as legendary as the rumor proclaimed, making him sound like a god! Jing Yichen was admired because of the power of Family Jing, and nothing else.
