It turns out that this Spirit Vein was discovered by the Shanyan Demon King six years ago.
At that time, the Shanyan Demon King had already reached the Middle Stage of the Golden Core.
It brought a group of its kin, the Shanyan Demons, migrating from the far northern edge of the Extreme North Icefield, across a body of water, taking over ten days and traveling tens of thousands of miles, to relocate here.
Since then, they have occupied this Spirit Vein and lived here for several years.
According to it, when it first arrived, there were no other Demon Beasts occupying this area, making it an unclaimed land where even the Human Race had not yet set foot.
This is the situation with this Spirit Vein, nothing much to say.
"The kin I brought with me number three hundred and ninety-nine, among which six have reached the Crystallization Stage, equivalent to the Tier Three Demon Beasts in your Human Race's terms."
