Chu Zhiyuan had already discussed this matter with Chu Qingyan earlier.
He also mentioned the extreme danger he sensed in Lu Yaofeng's Cave Mansion.
It is best not to open it lightly; several Great Grandmasters should act together, or investigate by other means.
People must not approach carelessly.
Furthermore, it is best not to investigate it at all, just let it remain there, unopened, as if unaware of its existence.
We must not let experts from Da Meng acquire it.
At that time, we could even let Da Meng's experts lead the way, while we reap the benefits.
Sadly, this Cave Mansion is well-hidden and has not been found.
Li Hongzhao had long anticipated this trick; the given position of the Cave Mansion is problematic.
His guessed direction is correct, but the position is off, perhaps shifting some distance east or west.
Watching Li Hongzhao leave in frustration, Chu Zhiyuan continued to study the Black Pearl, persistently refining it.
