One Dominating Attack

The expressions of the apex cultivators from the divine prefecture all turned rather solemn. Naturally, the Vajra Region Lord's attack was extremely powerful, as he was indubitably one of the strongest in the Divine Prefecture. Yet even his attack didn't manage to move the Battle Matrix of the Rocks. It was just like how the prodigies at Lost Clan back then weren't able to break the Battle Matrix of the Rocks.

But the difference was that those who were engaged in battle today were far more powerful. These were true overlords who were at the top of the cultivation pyramid. Of course, those who set down the Battle Matrix were stronger as well. These were the greatest cultivators of the Lost Clan. With their powers amplified by the Battle Matrix, their combined level wasn't as simple as a sum of their individual powers.

So, it's not abnormal that the Vajra Region Lord wasn't able to break the Battle Matrix.
