The Twelve Tribulations of the Purple Mansion.
The first tribulation is insufficient lifespan. Many Foundation Establishment cultivators are unable to reach the Ninth-Layer Foundation Establishment before their lifespan runs out, let alone attempt to break through to the Purple Mansion.
As for what comes next, purifying True Essence, opening meridians, unblocking acupoints, refining the Divine Soul, etc., there's practically no difficulty.
Those with money can buy Pure Yang Pills, Purple Mansion Pills, etc., saving a lot of time;
Those without money spend more time overcoming these barriers.
But when it comes to the Celestial Fire Tribulation, Nightmare Wind Tribulation, Celestial Human Tribulation, and others, failure means certain death.
At this moment, a Nirvana Pill is needed to prolong life, used for breaking down and rebuilding.
If there is a Nirvana Pool, the success rate is higher.
Back then, Ye Linglong fell during the Celestial Human Tribulation.
