Lu Zijia originally planned to upgrade the Taiyi Pill Furnace after arriving in the cultivation world and turn it into a dharma artifact at once.
But now, she had to change her mind.
This was because the Ice Sea Pill belonged to the type of pills that had a level of pills. If it was refined with an ordinary furnace, it would destroy the furnace every time she cultivated a batch of pills.
And now, even though she had prepared dozens of ordinary furnaces in advance, there weren't many left.
If this continued, she believed that it wouldn't be long before she didn't have a furnace to refine pills.
So, in order not to fall to the point where she didn't have a furnace to refine pills, she could only upgrade the Taiyi Pill Furnace briefly first, or at least increase the quality.
This way, she wouldn't have to worry about ruining furnaces every time she refined her pills.
