The size of the world within the Void Realm was about five times that of the room where Lu Xuan resided.
Such a vast world was more than enough for Lu Xuan to use.
The method of using the Void Realm was not complicated and was similar to the way a sacrificial artifact recognizes its master.
One only needed to inject a trace of their own power into it, leaving a unique imprint, to control the Void Realm with ease.
With a thought, Lu Xuan's mind instantly connected with the Void Realm, and the world within it vividly appeared before his eyes.
He saw a large, dark saber about half his height quietly hovering in the Void Realm.
On the blade of the saber were many naturally harmonious patterns, and the blade occasionally emitted a deep and mysterious glow.
The light was sometimes cold and eerie, and sometimes it became scorching hot, like fierce flames burning in the depths of hell, exuding a horrifying aura.
"Ghost Flame Nether Saber!"
"Seven-pattern Moon Artifact!"
