It's all for the Qi fortune.
For those above Divinity Transformation, talent doesn't matter much, unless it's to an extreme defying the heavens. Such beings cannot emerge without major fluctuations in the Great World, which simply don't exist.
Therefore, those above Divinity Transformation need the support of Qi fortune to break through.
Of course, most importantly, only with sufficient Qi fortune can one survive the celestial tribulation and become immortal.
After countless years of cultivation, absorbing a massive amount of energy from the Four Celestial Great World, I've reached the verge of becoming immortal.
To take this energy away, naturally, the Great World wouldn't willingly accept it.
If everyone did so, the Great World would decline.
Only with enough Qi fortune can the final thunder tribulation before immortality be weakened.
Although it's just a weakening, it's already extremely important.
Without enough Qi fortune, it's essentially impossible to become immortal.
