The Tieflings’ Hidden Lair 

Surrounded by ten Tieflings, Ren only looked at Pii, who wasn't even aware of the predicament he was in. It was joyfully chirping at Ren to check the statue out like Tieflings were invisible in its eyes.

Maybe Pii also sensed that Ren could defeat the Tieflings easily so it wasn't worried.

"I will look at it after I take care of this," Ren muttered under his breath.

There was no option not to engage. It was an ambush, so Ren didn't have any choice but to fight.

Ren didn't waste time on using [Probe] since he knew that the low-level Tieflings didn't have any useful skills or spells. It was a waste of time to use [Probe] on the ten Tieflings.

At this point, they were nothing but a raggedy bunch of thieves, and Ren could defeat them though he would suffer some HP reduction from their attacks since it was one against ten.

The Quest was obviously for a group of players like what Hoggy suggested they did. But soloing it with Ren's ATP wasn't a problem.
