Of course, the 'Ten-thousand-year-old Thunderstruck Wood Juice' brought by Junior Master Song was exchanged not for the refining of a single furnace of Fourth-grade Spirit Pills, but for three furnaces.
He had already decided that if Li Shiming's alchemy ability was too poor, he would swallow his pride and demand the 'Ten-thousand-year-old Thunderstruck Wood Juice' back, at most exchanging it for other Spiritual Objects.
This was something agreed upon beforehand, but if it had to be done, it would mean falling out with Li Shiming.
The agreed time was seven days, but Li Shiming took only six days to refine the Fourth-grade Spirit Pills this time.
The time saved was due to Li Shiming acquiring the phoenix line's alchemy inheritance, leading to an improvement in his alchemy skills.
The improvement in alchemy skills reflects an enhancement in his foundational alchemy abilities.
