Under the leadership of the hero Bartle, the Mercury Avatars settled by the Mercury River and began to develop frantically. Today, their number has reached an exaggerated three-digit figure, while their fighting power has increased several times.
Bartle had already made the next battle plan, which was to lure those demons to come for another hunt. But this time, it was not for intelligence but for research.
The race of Mercury Avatars, through inherited memories, devised a new type of biological modification technique from the engine transformation techniques of Hell Demons, theoretically capable of using demons' bodies as raw materials to strengthen the Mercury Avatars.
No one knew who proposed this theory; it started as a simple idea. As it circulated within the race, more Mercury Avatars added technical details and new content, quickly turning it into a highly feasible plan.
But this theory remained only on paper; now was the time to conduct the real experiment.
