Cursed by the Heavenly Dao, I Speedrun Immortal Cultivation with a Crippled Spiritual Root?

[Anti-套路] [Beloved Protagonist] [Heavenly Dao Suppression] [Pseudo Ensemble Cast] [Low Immortal, High Fantasy World] [Spirit Roots Determine Attributes and Exclusive Cultivation Techniques]

Ning Xiuyu awakens his past-life wisdom, and the will of the Heavenly Dao senses that an alien soul has invaded, intent on erasing him!

Unable to kill him, it lays a terrifying curse upon him.

But this curse seems to have gone a little wrong?

[Benefiting from medicinal pills: spiritual power -35, vitality -32, constitution -28, strength -15...]

[Afflicted by poisonous herbs: cultivation +32, vitality +29, spiritual power +18, constitution +17...]

Born with a useless spirit root, he thought cultivation was out of reach and that he could only go down the mountain to inherit his tycoon father's vast estate...

But Ning Xiuyu realizes that all he has to do is do things the opposite way, and he can surpass all those Daoist prodigies and saintesses?
