Zhou Feng's cultivation of the Human Emperor Scripture had become much easier due to his Tenacious Heart and his Self-Healing Constitution.
On the other hand, recovering from his injuries required a large amount of Blood Qi.
His Level-2 Gluttony could replenish his Blood Qi by constantly devouring various medicinal herbs and the like.
If there were pills, it would naturally be the best. In any case, Zhou Feng could convert anything into Blood Qi with his Level-2 Gluttony.
Therefore, Zhou Feng needed many resources to support his cultivation of the Human Emperor Scripture.
And what could he exchange for these cultivation resources? Currently, the best way for Zhou Feng to earn resources was to refine pills.
For him, refining pills could be said to be everything. He had pill-refining techniques, pill recipes, and even raw materials.
These things were all inherited from Pill Master Yuan.
