As for how to smuggle themselves, it was a case of every sorcerer showing their special skills.
They were both skeletons; they could extract their Soulfire and pack it into skeleton materials.
Olaf was a Thunder Dwarf, even more impressive than an average dwarf, capable of temporarily turning his body into a metal material, at which time the soul fluctuations would be very faint; with just a bit of concealment, the three of them could be smuggled in as "goods," considering Dragon Island didn't have strict security checks anyway.
Although Olaf felt this was rather hasty, he couldn't argue with Teacher Xia, who assuredly slapped his chest, declaring there would be absolutely no problem.
Considering these skeletons never dropped the ball in this regard, Olaf had no choice but to agree.
So, he touched the metal ornament in his beard and put all these gifts into his Void Bag.
This scene made Teacher Xia's mind wander.
