What happened with the first sealed item didn't affect what came next.
Unless they were directly over the hole, it didn't seem like the other sealed items were able to hear anything.
So it didn't matter what Lin Fan did, he was able to keep fooling the items in the holes.
There were others that gave up their treasures like the dagger did and in return, they were sealed just like the dagger.
However, there were also those that didn't seem like they were fooled by Lin Fan's words. So in the end, they didn't give up anything before they were sealed away.
Regardless of whether they gave up something or not, they were all sealed away by Lin Fan.
After all, it wasn't as if he could allow these sealed items to break through the seal.
In the end, he had to reseal them before they were released into the world.
