The primary ingredient for the Thunder Tribulation Pill is the Thunder Tribulation Wood.
Previously, when Lin Dong first arrived in Southborne, he acquired the Thunder Tribulation Wood, but he hadn't started refining it until now.
Now, he is ready to refine it.
As for the auxiliary medicines, Lin Dong has already prepared them all.
"This piece of Thunder Tribulation Wood can support at least hundreds of refinements for me."
"And for the other auxiliary medicines, I have also prepared enough."
Since this is the first time refining a fifth-grade elixir, Lin Dong cannot guarantee success on the first try.
He has even prepared for dozens of failures!
After studying the prescription, he prepared all the herbs.
Then, he took out the Five-colored Furnace and began the alchemy.
Placing the Five-colored Furnace in the middle of the Spirit Cave, Lin Dong raised the alchemist fire, controlling its temperature to thirty-five hundred degrees.
