The spatial fluctuations gradually subsided, and Su Xiao returned to the Exclusive Room. Thanks to the accumulation from the previous two Empty Seat Banquets, the gains from this one were exceptionally satisfying.
Su Xiao glanced at the Soul-Severing Shadow Stone floating nearby. Its fusion had been completed, but it still needed to stabilize, allowing the source energy within to settle before it could be used. One shouldn't forget that "Soul-Severing Shadow" was an ability developed by Green Gillian, the most vicious female Law-Destroyer in history. To master it, one had to be steady.
The ideal method was to meet Green Gillian's remnant soul first and ask about the details of "Soul-Severing Shadow."
The problem was that it was still unknown whether Green Gillian's remnant soul existed. As for asking the Old Law-Destroyer or Marvin Waltz, both of them had mastered "Demon-Eating Shadow," making them incompatible with "Soul-Severing Shadow."
"Demon-Eating Shadow" and "Soul-Severing Shadow" each had their advantages and disadvantages. The former required devouring Blade Demon's energy or sealing it inside the body. The Old Law-Destroyer and Marvin Waltz had done exactly that: one had devoured Blade Demon's energy, while the other had sealed it.
Su Xiao had taken a different route, sealing Blade Demon's energy inside his blade and thereby mastering the Demon Blade ability.
When "Soul-Severing Shadow" had been mentioned before, the looks the Old Law-Destroyer and Marvin Waltz had given him—you're on your own—undoubtedly represented the high risks of mastering this ability.
"Demon-Eating Shadow" was invincible in group battles, "Void-Breaking Shadow" had the greatest speed, and "Soul-Severing Shadow" was strongest in one-on-one fights. These three branches had all evolved from Blue Steel Shadow as their foundation.
After observing the Soul-Severing Shadow Stone for a while and deciding that it was still unstable, Su Xiao paid 50 Soul Coins
