When it came to brewing potions, Chu Fei was thoroughly familiar with the process. Although the "Enlightenment Potion" had only ever been simulated and deduced, never actually brewed, he had simulated it for so long that he had worked through nearly every step.
He took out a stalk of the poorest-quality Dragon Saliva Grass, a low-grade Dragon Gallbladder Fruit, a Golden Snake Flower of mediocre quality, and the remaining supplementary ingredients. Then Chu Fei began his first attempt.
Since it had all been based on deduction, and he was now using inferior ingredients, failure was inevitable.
Looking at the charred potion in his hand, Chu Fei was not surprised in the slightest. After pondering for a moment, sorting through the issues several times, and thinking them over thousands of times, he started again.
After three such attempts, Chu Fei had successfully brewed a 100% quality Enlightenment Potion using low-grade ingredients.
Whenever Master Chu made a move, the result had to be 100% quality. Otherwise, it would be an insult to all the foundations he had built.
Besides, it was ultimately a watered-down 13.0 potion. It was difficult for Chu Fei, but not excessively so. Could it possibly be harder than producing Spring Rain Incense?
Spring Rain Incense itself was a medicine at the peak of 13.0. With the medicinal catalyst and its two variations, its poisonous aspect might not have reached the 14.0 realm, but it was at least at the pinnacle of the 13.0 peak.
Successfully producing Spring Rain Incense meant that 13.0 potions no longer posed much difficulty for Chu Fei.
Of course, he had yet to study a genuine 13.0 potion involving laws, such as the Wind of Velocity Potion. But judging by the fact that the Wind of Velocity Potion was merely a "beginner" 13.0 potion,
