The Nine Heavens of the Thirteen Skies are a secret realm hidden above the Nine Heavens, also the place that holds the purest innate primordial qi.
Based on different levels of innate primordial qi, the Nine Heavens of the Thirteen Skies are divided accordingly.
Among the Nine Heavens, Qingxiao is the lowest, and Shenxiao is the highest.
The Four Heavens are divided into Daluo Heaven, Sun Wheel Heaven, Moon Wheel Heaven, and Wanxiang Heaven.
Of these, Wanxiang Heaven is the lowest, and Daluo Heaven is the highest.
Cultivators who have passed through the tribulation sever the thunder tribulation and can rush into the Nine Heavens of the Thirteen Skies to absorb the innate primordial qi.
The higher the heaven level entered, the greater the benefit.
Every cultivator crossing the thunder tribulation understands this very clearly.
They must seize the chance to sever the tribulation lightning and ride the momentum upward into the Nine Heavens of the Thirteen Skies.
This is extremely dangerous.
If they fail and are instead blasted to death by the tribulation lightning, their demise would be truly tragic.
For those crossing the lightning tribulation, the most important thing is to protect themselves first.
