In the history of the Human Race, the Ninth Tribulation Realm has never been reached by any cultivator.
First, because it's too difficult, and second, because it's unnecessary.
It's like being able to attend Tsinghua or Peking University with a score of 700, and then going on to study more profound knowledge; no one would choose to repeat a year just to reach an elusive score of 750.
Throughout the cultivator system, only the sword cultivators, who need to forge their own path, have gone the farthest in the Tribulation Crossing realm and are most likely to touch upon the Ninth Tribulation Realm.
But it's important to note that even with the talent of someone like Li Qiubai, he only stopped at the Eight Tribulation Realm, ascending to the Sword Immortal Realm.
It's such a "priceless yet unattainable" Ninth Tribulation Realm, yet the message conveyed in Chu Mu's myth is that Lu Qingshan will definitely reach it, completing this unprecedented achievement.
