Marrow Devouring Poison, Cunning and Resourceful

"Refining poison really wasn't easy!"

"For a pill capable of killing a Marrow Cleansing Grandmaster, not only were the poison requirements demanding, the refining process was also extremely difficult!"

After learning that he would be attending the Divine Pill Ceremony, Yang Chan began preparing means of self-protection.

From the memories he had received, he chose a poison called Marrow Devouring Poison, specially designed for Marrow Cleansing Grandmasters. Once poisoned, it seeped deep into the marrow, like poison clinging to the bones, difficult to dispel.

The refinement process for this poison was also highly complicated. Some stages required using earthfire to refine the poison, while others required water-method poison compounding. Only by completing every step in sequence could it be successfully refined.

If anything went wrong midway, the poison's potency would be greatly reduced. It would be incapable of harming a Marrow Cleansing Grandmaster, much less poisoning such an expert to death!

Only after his Pharmacist profession advanced and he received the memories' feedback did he learn the complete refinement process. Even so, he had still failed several times.

Overall, its refinement difficulty was no less than that of refining Marrow Cleansing pills.

If he did not have those related memories in his mind and tried refining the poison directly, he would most likely have failed!

"Although the poison-refining process wasn't very smooth, I still managed to refine the Marrow Devouring Poison!"

"This bottle should be enough!"

"When used together with that set of Famous Artifact-grade hidden weapons, it can kill a Marrow Cleansing Grandmaster!"

Yang Chan's successful poison refinement was naturally meant to guard against unforeseen circumstances. He already possessed hidden weapons capable of breaking a Marrow Cleansing Grandmaster's defenses, and now he also had poison. Naturally, his safety was greatly enhanced!
