When Zhou Yu received the inheritance of Ancestor Dragon Hei Cang, he learned from Hei Cang about the Sealing Demon Valley below, where a Demon Lord was suppressed.
He also came to understand the details of this Demon Lord.
Speaking of which, this Demon Lord was once a member of the Dragon Clan, but later betrayed the Dragon Clan and defected to the Dark Clan, becoming the Shadow Demon Dragon!
The Shadow Demon Dragon caused severe damage to the Dragon Clan. Later, after being defeated by Thunder Ancestor, it was handed over to the Dragon Clan for suppression.
The Black Dragon Clan suppressed it in the Sealing Demon Valley, and generations of Dragon Kings were buried there after their deaths, using their Dragon Souls to suppress it forever.
However, in the Ancient Phoenix Fall Land, another Demon Lord is also suppressed.
Now, there's a problem with the Demon Seal in the Ancient Phoenix Fall Land, which indirectly affects the Sealing Demon Valley.
