"The rebel Dongfang's attainments in alchemy have actually reached such an astonishing degree." Wu Daoxin and Luo Yuanliang both changed expressions.
The three types of immortal materials that Lu Xiaotian threw into the three pill furnaces were completely identical, the only difference being the slightly varying quantities of a few of those immortal plants.
In the eyes of an ordinary Grade 1 Grandmaster Alchemist, this slight difference was almost negligible.
Yet Lu Xiaotian utilized his exquisitely minute control to simultaneously modulate the medicinal liquid and fire intensity within each pill furnace.
He scorched the medicinal liquid with different fire intensities, and then divided the medicinal liquids of varying proportions into different batches to mix them.
Ultimately, this caused the medicinal pills within the three pill furnaces to undergo slight, subtle changes, gradually forming various different classes of medicinal pills.
The principle looked rather simple, but Wu Daoxin and the others, as Grade 4 Grandmaster Alchemists, knew how immense the difficulty was for Lu Xiaotian to refine three furnaces of pills simultaneously by himself and brew different kinds of medicinal pills using the same immortal materials.
Even though both sides were in a hostile relationship, Wu Daoxin did not feel that refining a Tier 4 immortal pill would be any more difficult than Lu Xiaotian's current operation.
Han Shiqi's face also sank completely. Originally, the medicinal pills refined by the three of them were extremely similar, and their pill Qi could also merge together relatively seamlessly.
It was far more powerful than the pill Qi gathered by three unrelated immortal pills, and it was also much more convenient to control.
Who would have thought that Lu Xiaotian would actually use such a method to simultaneously refine three immortal pills including the Taixu Guiyuan.
When taken out and compared individually, these three
