One year later.
After several months of recovery and resting, Grimm proceeded to the Tomb Segja Sorcerer Academy to report his findings in the mission—"Observation of the Eternal Destructive Energy" assigned to him a hundred years ago. After reviewing the formation of the Destructive Energy's thirty-six foundations, he was reclaimed.
Returning to his Demon-Hunter Castle, Grimm couldn't wait to gather and assemble his experimental equipment.
The Eternal Destructive Energy Meter was finally completed after three painstaking days of careful assembly by Grimm.
This piece of equipment in front of Grimm was the largest, most intricate machine he had ever assembled in his life.
There were many other experimental equipment and instruments in the Demon-Hunter Castle but this particular one seemed much more mysterious and gave off a feeling like it belonged to an ancient laboratory.
The instrument was fifteen meters high.
