The ancient secret realm exploration became the worst accident all of a sudden. The threat of invasion from countless demonic monsters and ancient demons was obvious.
A few hours after the disciples entered the ancient secret realm, thousands of monsters emerged from the realm's portal. A battle was unavoidable, but those monsters were no match for many groups of influential experts from the outside world.
A great war between demons and humans would break out soon, but the monster's invasion made them have other priorities.
When a 10th Rank ancient demonic monster was about to emerge out of the portal, Yuuki made her move to push that monster back into the ancient secret realm.
Gabriella and Rafaela also helped, but the others still observed the overall situation as a backup plan from somewhere hidden.
The allied forces managed to slay the demonic monsters. After that, they entered the ancient secret realm to check the situation on the other side.
