Heavenly Tribulation!
It is said that in a cultivator's life, one must transcend the heavenly tribulation three times.
Each time consists of three rounds, making a total of nine rounds, hence called the Three Nines Heavenly Tribulation.
For cultivators, each heavenly tribulation is the most perilous challenge on the path of cultivation.
If one overcomes it, it will be like a bird soaring in the sky, and their realm and power will undergo a world-changing transformation!
But if one fails to transcend it, they will sink into the abyss, never to rise again.
For the Demon Clan, the terror of the heavenly tribulation is far more dreadful than it is for the Human Clan.
Human cultivators often possess various means, leveraging the Hundred Arts of Immortal Cultivation to enhance themselves, facing the heavenly tribulation with relative ease.
