Chapter 816: River of Vigor

Michael decided to test River of Vigor right away. He infused a small amount of energy into the Soultrait Symbol and received an immediate response. 

The exhaustion that had plagued him was no more. A rush of soothing energy swept through his body, washing away his exhaustion. But that did not only include his body's exhaustion but also his mind and soul. Even the weariness of his Soul expanding unnaturally was no more. It felt like he had never been in pain in the first place. That was very interesting.

'Even the psychological pain and exhaustion is no more.' Michael concluded with a grin. This could be very useful. Using River of Vigor after several hours of fighting would help him return to peak condition. If utilized properly, Michael could turn the tables in various fights that would be very difficult to win under normal circumstances.
