The barrier used by Demon Baal is quite ancient, designed to envelop both himself and the target, engaging in battle within.
Once this skill is completed, it is difficult to destroy the barrier whether attacking from inside or outside.
To dissolve the barrier, a considerable amount of effort is needed to unravel the encryption technique constituting it.
The angels use Holy Light and don't understand magic, leaving them with almost no means to deal with this barrier.
Initially facing angels, demons were far inferior in strength to angels.
Ancient humans, to prevent demons from fearing angels' power, did not teach demons how to unravel the encryption technique, which led to angels escaping when they actively dissolved the array.
After demons trap angels, they are often eliminated by angels.
Facing the barrier, angels are not completely helpless.
The Twelve Angels wield twelve Holy Artifacts, which possess the ability to slice through the barrier.
