If anyone besides Xitasil was most familiar with this underground labyrinth, it was naturally Tu Shenyi, the castle's nominal master.
In fact, aside from the renovated Stone Chambers that had been publicly revealed, there were many secret rooms here—including the one Xitasil had initially used to receive Luo Qiu.
