Reaper Spirit Iron
Old Wan hardly had the time to react before he was completely taken off guard. He didn't even have the time to register the pain either before a black box within his spatial ring began to tremble wildly.
His expression changed.
This black box wasn't just a normal item; it was one of the treasures that he received from the Taboo Sect he happened upon the legacy of. It was known simply as the Soul Box.
The Soul Box was made of a special material that had long gone extinct, mostly because it had been wiped out along with the Soul Reaper Sect.
The material was known as Reaper Spirit Iron and it had two main functions.
The first was that the first soul it came into contact with, it was capable of replicating the fluctuations of and becoming an eighth Corporeal Soul and the fourth Incorporeal Spirits at the same time.
