Sure enough, professional work was best left to the professionals!
Back when Nalan Sheng watched anime, for instance, he had already known about the first-generation aging drug, but he had never thought of using it for cultivation.
What excited Nalan Sheng most was that, since the second-generation aging drug could accelerate the absorption of Foundation Establishment Spirit Liquid, it could surely improve the absorption of other pills as well.
"Nezuko, aside from accelerating the consumption of the target's lifespan, are there any other side effects to using the second-generation aging drug to assist cultivation?"
A thoughtful gleam flashed through Nalan Sheng's eyes as he asked another question.
"My lord, there are two fairly noticeable side effects."
Nezuko nodded slightly and held up two slender fingers. "The first is that absorbing large quantities of Foundation Establishment Spirit Liquid in a short time causes a great deal of pill toxins to accumulate in our bodies, which affects our future cultivation.
"But we've already resolved that side effect. I just need to burn away those pill toxins with my Blood Demon Art.
"The second is that the Dou Qi we cultivate is rather insubstantial. Although we can absorb a bottle of Foundation Establishment Spirit Liquid in two days, we have to spend several times that long consolidating our cultivation afterward."
"I see."
Nalan Sheng smiled at her words. "You don't need to worry too much about the insubstantial Dou Qi, either. I'll find a way to resolve that for you as soon as possible.
"The Heavenly Flame ranked fourteenth on the Heavenly Flame Ranking is called the Fallen Heart Flame. It's a transparent, colorless Heavenly Flame.
"This flame can continuously produce a special flame called heart fire, which tempers Dou Qi and accelerates cultivation. That's why it's also known as a cultivation cheat.
