"Yes, keep looking."
Lin Caisang nodded fiercely and called out Hongjin and Hongyin as well.
"We must find the peculiarity of this place."
...
Half an hour later, Lin Caisang and Sui Zimo finally found a hidden passage in the wall beneath the stove.
"Tsk tsk."
Lin Caisang clicked her tongue lightly as she looked at the stone door that had been moved aside.
"This stone door is so thick, wouldn't it be impossible to find no matter how much one knocks?"
You could identify a hollow wall by knocking, but only if the wall was very thin.
But the stone door they had just found was almost as thick as a city wall.
Such a hidden chamber wall would definitely be missed by most people.
"Brother Molian, if you hadn't noticed the difference in space between the outside and the inside of this place, we really wouldn't have been able to find this secret chamber. It's very well made!"
"Let's go inside and take a look," Sui Zimo said, glancing down at her.
"Mhm."
