The mechanism lock is also a type of mechanical technique, slightly more refined... Don't be fooled by the fact that most mechanism locks aren't particularly large, their complexity is beyond imagination, even some mechanism locks once set successfully, not even top-notch mechanical technique experts can unlock them.
For instance, the most feared mechanism lock in Thousand Gate history was named the Void...
No one has managed to unlock this mechanism lock to this day!
Of course, this type of mechanism lock has long been lost... In the entire history of mechanism locks, there's only this one, and it was accidentally completed by the master who set it, even he couldn't solve it.
Aside from this unsolvable mechanism lock, there are some extremely perverse mechanism locks...
