As expected, the battle-tempered blade is indeed a good partner for the Fierce weapon of blood sacrifice. Not to mention, Ji Jue even spent money to buy the Path of Ascension's blessing [One Heart's Devotion] from the association, further asserting the ferocity of Pan Ying and enhancing the efficiency and stability of the blood sacrifice.
The main material for the sword blank was the Stone Marrow sent by Sister Wen. Besides that, Ji Jue also added his own blood, Dragon Blood from Little Nimble, and many Corrupted auxiliary materials scavenged from Spring City, even the corpse of that old boar from the ether on the cruise ship.
Additionally, Ji Jue was afraid the campus wouldn't be violent enough, so he added more potent material, mixing in some Corruption Alchemy tricks he learned from Old Boar Jian Yuan...
Thus was formed the shape of the Fierce weapon Pan Ying!
