The exploration of the Helentz Castle underground ruins is completely over.
Roland certainly wouldn't enter a dangerous underground cave with an adventure team like the protagonist of an adventure novel, risking life and death only to find a pile of junk.
His life is valuable, and he doesn't want to take risks.
Exploring ruins is different from fighting; if there are deadly traps governed by rules, even the strongest combat skills won't help.
He doesn't have a Resurrection Coin, so unless it's absolutely necessary, he's not going to take risks.
The chances of escaping after a failed ruins exploration are very low, unlike a battle failure where there might be a retreat option.
A wise man doesn't put himself in a desperate situation; such adventures should be left to the professionals.
He found a top-ranking professional team in the industry called "Armadillo."
