In that short window of time, Rain teleported behind the enemy and then stabbed their heart with his own arm… in the next moment, all of the essence of the enemy was sucked into a single red core that Rain created with it.
The skill Teleportation leveled up.
The skill Spatial Manipulation Mastery leveled up.
The skill Limit Breaker leveled up.
…
Rain sighed in relief… he won before anything too drastic could happen. Still, it wasn't over yet. He teleported where the others were and soon confirmed that they were about to finish their retreat.
"We are going to continue our attack," Rain said. "Rest as much as possible."
Naturally, that wasn't the case… It was only a countermeasure in case the enemy was watching them. As soon as they finished the retreat, Rain got Iori core and then teleported back to Earth, using the remaining mana on both gems.
