ZullieTheWitch, a well-known game data miner and hacker in the Dark Souls series, recently said on Twitter that the hidden doors in "Eldon's Ring of Law" that need to be opened many times are not only found in the volcano mansion, so far she has found 7 hidden doors on the wall and one hidden door on the ground to be opened N times.
But she said some of the hidden walls didn't make sense, and the rest were hard to prove. The news caused a stir in the Reddit Old Man's Ring community, with some players saying that from now on they would not let go of any hidden walls that might exist, and would have to knock on them a few more times.
When asked how she found it, she said that through modeling data it was visually possible to identify which area the hidden door belonged to, and when she ran the program to check the map of these areas, although the hidden door had been loaded into the resource list, it was never used, and it was possible that it was scrapped but not completely deleted.
For the two hidden doors that are currently found in the volcano mansion to knock N times, she guesses that it may be an oversight of the development work, and it is reasonable to say that they should be the same as other hidden doors, which will be opened directly after being attacked, but the HP of these two doors has 9999, and also lacks the trigger to eliminate the hidden wall after the collision, so it is necessary to attack multiple times.

In fact, even if these hidden walls are opened, they should not give any good things, and they will not affect your full achievements in platinum or Steam at all, so players do not have to deliberately spend time to find some meaningless hidden doors, these are left to those "explorers" to do it, ordinary players still enjoy the game.
