Inside the City Lord's study, Su Xiao sat on a crystal chair, his eyes fixed on the password cabinet ahead. He had been in an excellent mood after seeing the two "Primordial Fragments" inside, but the soul container that followed suddenly made the situation extremely complicated.
That familiar yet strange soul aura made Su Xiao realize that it was familiar because it shared the same source in terms of its power system, but strange because he had never seen this soul before. What could satisfy both conditions? The answer was obvious: the remnant soul of a former Law-Destroyer.
Although a Law-Destroyer remnant soul could exist for a long time, it could not last for an absurdly long period. In other words, only the last few former Law-Destroyers before the destruction of the Law-Destroyer faction could have left remnant souls.
The former Law-Destroyers Su Xiao knew of were:
Marvin Waltz (the unscrupulous mentor).
Old Law-Destroyer (the unscrupulous mentor's master).
Star Devourer Akas (the most reliable former Law-Destroyer).
Ximan Archid (Shadow of the Abyss).
Green Gillian (the most vicious Shadow of Law Destruction in history).
After excluding Ximan Archid, Marvin Waltz, and Old Law-Destroyer, the remnant soul inside this container should belong to either Star Devourer Akas or Green Gillian.
With that thought, Su Xiao reopened the password cabinet. If this was Akas's remnant soul, that would be wonderful. Whenever he failed to understand one of his abilities in the future, he could ask this former Law-Destroyer for advice. Sometimes it was not that his unscrupulous mentor and Old Law-Destroyer did not want to teach him; it was that when it came to explaining their abilities, they were even more confused than Su Xiao, the student.
A long time ago, Marvin Waltz had tried to teach Su Xiao the "Undying Physique"
