If it were an ordinary stone door, it wouldn't be so troublesome.
Not only would a simple stone door be no obstacle, but even a divine wall made from Wall of the Divine Kingdom would not be able to withstand Sterl's strength.
However, the key here was that this stone door was connected to the core of the entire Abyssal Prison. It was the backbone of the Abyssal Prison, and forcibly destroying the door would be the same as confronting the entire Abyssal Prison head-on.
Moreover, his Dimension Perception occasionally sent out a sense of impending danger. If he forcibly broke the door, something unpleasant would occur.
He wasn't entirely sure what would happen, as his knowledge about Abyssal Prison was still too limited.
The information he obtained from the Ghost Old Man and that unfortunate creature was extremely one-sided. After all, they were Ultimate Evil Beings imprisoned in the second level of the Abyssal Prison and had no knowledge of what lay in the fourth or fifth levels.
