The coffin he had acquired was a damaged True Dao artifact he had obtained by chance, a treasure from an ancient age.
It was severely incomplete, capable at most of unleashing power at the Supreme Heavenly Lord level.
Yet the True Dao within it had not vanished entirely. A faint remnant remained, and the mysterious coffin avatar had used it to evolve this punch that could Bury the Heavens.
This strike was extraordinarily terrifying, raising his power by another twenty percent.
But the Superposition State sealed the Eternal Deadlands, allowing all power to be transferred instantaneously and gathered in a single moment.
Moreover, Avenger had been quietly observing the outside all along, coordinating seamlessly to marshal the power toward the same point.
The two forces instantly converged, forming a barrier.
The punch that could Bury the Heavens slammed heavily into it, flashing with a wondrous principle that transcended all things.
Both the Superposition State and the Eternal Deadlands were violently shaken. Countless cracks appeared across the Superposition State at once.
Yet in the end, that punch still failed to shatter the Eternal Deadlands.
The Mysterious Immortal flickered madly like flowing light, appearing at every corner of the Eternal Deadlands and launching attack after attack.
He had naturally long since seen through the defensive methods of the many powerful figures of the Ultimate Universe.
But however he moved, the Great Vow Daoist adjusted the distribution of power accordingly, never giving him any chance to break through.
Avenger within also cooperated. The two layers of defense, inside and out, precisely locked onto every one of his attacks.
After merely a single breath, the mysterious coffin avatar knew there was no solution to this situation.
"No. There is no point in continuing this entanglement. My power is insufficient; I cannot break this seal."
