Caught it!
This time, I actually caught a tangible object instead of passing through the void and returning without effect. Naturally, there was no punishment this time.
Upon opening my eyes, I saw the treasure inside the red copper pillar was indeed taken out by Ye Rong. It was the scabbard in his hand that could gather and disperse at will.
Ye Rong unexpectedly met the treasure-taking condition on the last Sky Pillar Treasure Copper Pillar and successfully took the scabbard out.
"Huh, why did this scabbard suddenly change its shape, and it's been identified already!"
Grabbing it in my hand, it felt as if holding a cloud, an illusory feeling like it's there and not there at the same time. The scabbard transformed into a sword box.
