Yang Chen began to observe carefully.
Others could not do it, but Yang Chen could accomplish it with ease. Activating the Spirit Resonance Divine Eye, he could casually see through the Baleful Demon's body and discern its crucial weakness.
"So that's how it is..."
Yang Chen murmured to himself.
The fundamental reason these Baleful Demons had gone mad and become Baleful Demons was, in truth, the demon qi within their bodies.
Killing Intent was something exceedingly difficult to control. In fact, the Earth Fiend Clan could be considered a clan of astonishing geniuses. From the Ice Fire Heavenly Phoenix's tone, even in their greater realm, control over Killing Intent seemed fairly mediocre.
Yet the Earth Fiend Clan had succeeded. At the root of it all was their fusion of the Ancient Monster Race and Ancient Demon Clan.
And among them, the Ancient Demon Clan was the key.
Only by relying on the Ancient Demon Clan's demon qi to suppress it could they restrain that Killing Intent.
But as the ages changed, the Ancient Demon Clan bloodline within these Earth Fiend Clan members grew thinner and thinner. As their Killing Intent cultivation became stronger, they simply could no longer suppress it.
This caused their Killing Intent to break free of control and erupt together with their demon qi, turning them completely into Baleful Demons.
Thinking of this, Yang Chen secretly felt fortunate that he had relied on Black Demon Qi to suppress his own Killing Intent. Black Demon Qi rivaled the most primordial ancient demon qi, and it was the purest demon qi of all, capable of perfectly suppressing Killing Intent.
Had it been ordinary demon qi, with his Ten Revolutions Divine Transformation already cultivated to the ninth revolution, he likely would have been unable to keep his Killing Intent suppressed
