Ch. 221Imperial Arms Modification Blueprint (Fourth Bonus Chapter, for Alliance Leader "Feng Feng Piao")
Su Xiao followed Akame into an underground passage but lost her trail at a fork and discovered a sealed laboratory instead. He survived its poisonous gas and escaped with a Purple-quality Imperial Arms Modification Blueprint.
- Su Xiao found a tunnel beneath the Imperial Capital headquarters and pursued Akame through it, using his new ability to sense enemies he had injured.
- He found Akame's blood and torn undergarment, then chose the wrong branch and reached a dead end.
- Su Xiao spotted a rusted metal door bearing the Empire's flag and spent an hour cutting an opening through it.
- He entered a hidden laboratory, triggered Kanyat Poison Gas, and rushed in to grab a glowing parchment before retreating.
- Su Xiao identified the parchment as an Imperial Arms Modification Blueprint for combining biological and item-type Imperial Arms with Super Dangerous Beast essence.
