Every time the soul master reaches the level 10 soul force bottleneck, he needs to hunt the soul beast to obtain the soul ring, so as to break through the bottleneck and continue to improve the soul force level. Each soul ring corresponding to the soul beast has corresponding soul skills, and different soul rings can produce different skills when matched with Wu Soul. A soul master can bring up to 9 skills, but there are 4 slots for actively releasing skills.
