It took Watson less than half an hour to find the gate of the palace treasure warehouse.
Watson quickly swam to the big lock and found a suitable key, but he didn't open the door after turning it a few times.
Maybe it was because it hadn't been opened for a long time, or maybe it was because the key was wrong?
Watson tried several more keys but to no avail.
He couldn't give it a try anymore, but Watson had never done it himself before.
In the past, the work of opening the treasure warehouse door was done by the professional members of Watson's team.
The most difficult treasure warehouse, such as the door of the Pirate Bay in Royale Harbor, was also studied by Lenobili and the old locksmith, Anthony.
It was opened by Lenobili.
Watson thought that it wouldn't be that easy to open the treasure warehouse. He had seen the wisdom of ancient people with his own eyes.
After carefully observing the lock and the key mechanism, Watson finally found the rule.
