These three S rank extraordinary ability users were Gabriel Reis, Macmillan, and Alger.
The three of them were all strong mages guarding the seventh level of the dungeon in the headquarters. The seventh level of the dungeon contained S rank strange creatures.
These strange creatures were basically the A+ rank strange creatures captured by the Salko Temple. After being cruelly exploited by the Salko temple, they still survived. They finally succeeded in advancing.
These S rank strange creatures were almost all auxiliary strange creatures. The battle-type strange creatures had long been absorbed by the Salko Temple.
These S rank strange creatures would be sent to the New World after being guarded for a period of time.
In the New World, the S rank strange creatures were fully exploited. The four S rank strange creatures on the seventh floor were sent to the New World.
