"I've built up quite a reserve this time!"
For this breakthrough, Medivh had prepared a batch of Mid-Grade Red Bone parts that had never been revived before.
To his surprise, the mental-power-activation effect from reviving the Mud Swamp Dragon skeleton hadn't even faded before he broke through his mental-power bottleneck and advanced to Fourth-Rank Advanced Necromancer.
A breakthrough this easy was all the better. There was no need to struggle with everything he had just to feel a sense of accomplishment.
After advancing to Fourth-Rank Advanced Necromancer, Medivh gained the ability to revive top-grade Red Bone Common Skeletons and High-Grade Red Bone Transcendental Skeletons.
A top-grade Red Bone Skeleton started at the peak of the Fourth Rank. With a little cultivation, it could cross the threshold and advance to a Fifth-Rank Bone Spirit.
However, complete ordinary skeletons naturally preserved for 2,550 to 3,000 years were exceedingly rare. Such skeletons could only be found in special environments like the Frozen Tundra, or in unusual graves and ruins.
Common Skeletons weren't as powerful as Transcendental Skeletons, but they were still peak Fourth-Rank Bone Spirits, so Medivh was happy to set aside time to refine and revive top-grade Red Bone Common Skeletons.
Even without a transcendental system, a Fifth-Rank Bone Spirit was still useful simply because its sturdy bones could absorb damage.
With a tough front line to hold the enemy's attention and a group of lower-tier damage dealers behind it, a force could fight beautifully.
There were many recorded battles in which different Skeletons worked together to defeat stronger enemies across ranks.
High-Grade Red Bone Transcendental Skeletons were the main targets of dragonblood cultivation.
Before Medivh advanced to Fifth-Rank Necromancer, his way of obtaining Fifth-Rank Bone Spirits was to cultivate them using the Time Skeleton's growth potential.
"Nineteen long years, and I've
