Chapter 299 Perfection

After millennia of confrontation, the Heavenly Master Lineage, if not masters of the Demon Spirit, knows eight or nine out of ten secrets about them.

Of course, as the Heavenly Masters evolve, so do the Demon Spirits.

Just like the birth of the first Heavenly Monarch ten thousand years ago and the first creator three thousand years ago, Demon Spirits are also continuously transforming in the process of competing with humans.

From the ordinary Demon Spirits to the medium-sized ones, then to those over ten meters—large Demon Spirits, and even those over thirty meters—Catastrophic-level Demon Spirits.

Generation after generation.

The contention between two civilizations is almost a comparison of the speed of evolution.
