The third round of forging also began with nurturing the blade.
"Nurture the blade with one's body; minor success in several years."
"Unsheathe the blade, slay one hundred. Forge it in raging fire, let it devour corpse and bone, with runes of fresh blood written inside the bones."
"When the blade is forged, use your body as its sheath, nurturing it for one hundred days."
"Then unsheathe the blade again, behead over a hundred. Repeat the cycle, until three thousand have been slain."
"On the day the Great Decomposition Saber is complete, the Hundred Ghosts will flee and Arhats will crumble."
The third round for the Great Decomposition Saber was clearly a lengthy project.
First, one had to nurture the blade with their body for several years. When it was deemed ready, they would go out and kill.
After killing 100 people, it would be forged anew. This time, the blade's body would devour bleached bones covered in runes of fresh blood.
