"Demons!"
The old master's face changed instantly.
As a powerful figure surviving from the Ancient Times, he naturally knew what the so-called demons truly were.
It was a method used by the Ancient Demon Clan to cultivate puppets.
After all, although the Ancient Demon Clan generally had high power, their numbers were far less than humans.
In order to fully invade Earth.
The Ancient Demon Clan targeted Earth's inhabitants.
The Demon Fog they carried had the capability to invade human bodies.
Once the fog completely invades, it can consume human consciousness, turning a living person into neither human nor demon—known as a demon!
These demons would be directly controlled by the Ancient Demon Clan, becoming their directed puppets, each one possessing immense strength and formidable power.
In the past, Earth lost many experts dealing with the demon army controlled by the Ancient Demon Clan.
