Guding and his companions naturally couldn't know what was happening on the spacecraft; they were still in the secret realm, trailing the Dark Clan group by two full days.
After all, the Dark Clan group had entered three days before Guding and his team, and had already procured a few Fake Spiritual Objects. Over these two days, they had also found the location of the warehouse, but when they saw the two Platinum Skulls standing guard at the warehouse entrance like gatekeepers, they decisively chose to give up. Instead, they shifted their target to another location guarded by a single Platinum Skull, which was a Time Acceleration Hut previously scouted by the Sea Emperor.
Naturally, the Dark Clan did not know what this hut was, but they assumed it contained some treasure, hence it was guarded by a Platinum Skull, just like the warehouse. However, with just a single Platinum Skull as a Pet Beast, they took a risk on this particular hut.
