The step of solidifying the pill is not as prone to errors as the fusion of ingredients.
It mainly tests Lin Dong's ability to control the heat.
Of course, the factors affecting the solidification of the pill are not limited to just the heat.
The alchemy furnace is also very important.
Fortunately, the Five-colored Furnace is a middle-grade furnace. Moreover, it recognizes Lin Dong as its master. During the process of solidifying the pill, it releases the elements of the Five Elements, merging them into the 'material pill'.
As a result, the probability of making mistakes is even smaller!
However, there is one crucial step in solidifying the pill, called 'refining the lines'.
A first-grade pill has one alchemy mark. A second-grade pill has two alchemy marks...
By this analogy, a fifth-grade pill has five alchemy marks. The more alchemy marks, the greater the difficulty of 'refining the lines'.
