Part 2: Ella appears on 15th floor
Gritting her teeth she takes out the life saving artifact from her storage ring. It's a one time attack artefact. This artifact stored her father's one time Peak Elite level attack.
While ago she already understood the pattern of this challenge. She really wanted to use it on a higher floor but not now. But seeing the category of the monster and their numbers. She doesn't have any choice other than to use it.
She shows the green color pendant artifact against those monsters from a distance. As the blood drops on it from her finger, the artefact activates in an instant.
At this moment, an overbearing aura envelops the entire space of the 15th floor for a moment. Even before the actual attack falls on them. The five monsters dissipate into thin air due Peak Level Elite pressure.
And the next moment,
"Boom"
