In the most needed Passive Skills, unable to find anything suitable, Gu Xi's gaze shifted to the Professional Skills.
This time there were more Skill Books available.
Most of them were skills the Undead Mage should learn, such as the Secondary Corpse Burst promoting to Corpse Explosion Skill, then there was Bone Spike promoting to Bone Spear, Bone Shield promoting to Bone Cage, and so on.
Or some new skills, such as Poison Cloud Technique, Weakness Curse, and so forth.
There were also skills specifically for enhancing the Undead, such as Undead Experiment, Undead Evolution, etc.
It could be said that there were far more skills here than earlier ones.
Gu Xi picked them, choosing ones he could utilize.
He had three battle merits left, so Gu Xi had to consider his situation carefully in making his choices.
