Two hours—neither too long nor too short.
For martial artists who have barely reached the standard of a first-grade Alchemist, successfully refining a first-grade elixir within this period is quite challenging; time is extremely tight.
But for a second-grade Alchemist like Zhao Letian, two hours is more than sufficient, even overly so.
"Advance as long as I'm among the top one hundred? Considering that, I'll keep a low profile in the first round and casually refine a first-grade elixir."
Zhao Letian thought to himself while his hand flickered with Spirit Light, promptly taking out the Hundred Herbs Furnace.
"Whoosh!"
Following that, Zhao Letian opened the Pill Furnace and casually threw in some herbs.
His movements seemed casual, but each type of herb thrown in was precisely matched in specific proportions.
The first step in Alchemy is to blend the herbs.
The second step is to use the flames to refine the herbs, removing the dross and retaining the essence.
