His vision shifted to the Blood Ancestor's third-person perspective.
As she descended through the opening, the secret passage was only half a human body wide. The Blood Ancestor transformed her flesh into a solidified sphere of blood and continuously moved downward through the passage, entering some unknown space of absolute secrecy.
It was simply impossible to reach the secret chamber without passing through the passage beneath the Bixun River. This was an entirely independent space established by the First Generation Blood Ancestor.
The enormous underground space was crimson, but it was not completely open. Instead, it was divided into separate rooms.
Much like the Ghoul Realm Treasure Vault, it stored treasures, books, and unknown secrets collected by the Blood Realm since its founding.
The items stored in the staggered rooms varied in value. The closer one got to the center, the more valuable the items became. However, the destination reached whenever one opened a blood door was different. Only a Blood Ancestor undergoing inheritance would know the route through these rooms. There was no mathematical pattern to it at all; it was like an underground labyrinth made up of thousands of chambers.
After passing through fifty-three doors formed of blood, the Blood Ancestor arrived in a circular room completely unlike the previous ones.
The room was built from a transparent crystal mineral that emitted a faint reddish glow. Historical records of the Blood Realm stated that it had existed thirteen thousand years ago and was found exclusively in the Bixun River. The First Generation Blood Ancestor had named it Xinjing Blood Ore.
Xinjing Blood Ore was not like Zhang Chen's blood fetus, capable of storing vast amounts of Bixun River blood energy. Its overall blood energy content was not high, nor was it as precious as so-called Divine Artifact materials.
