A Minor Plane?

The other elders had never thought that something like this happened in their sect and wanted to know more.

"Wait, I remember that. I was still an inner court disciple when that happened. A strong intruder apparently managed to slip into the sect. There were many other experts from different sects chasing him as well.

Our sect was near to the battle zone and they made a plan to coax him into the area of our sect so we could trap him." The elder replied.

"What happened after that?" the other elders curiously asked.

"The plan did succeed, but not without a cost. Elder Limo, along with seven other Nascent Soul realm elders of different sects, died in the battle." The elder answered.

"What? The enemy managed to do that? Who was he and what happened to him?" they asked further.
