The maze opened. The maze that trapped the strongest of this realm and some other realms nearby opened.
When it was opened, only two people remained alive.
The Saber Monarch and the third family head. But they didn't come out of the valley. Instead, Sam went into the valley to do something.
As soon as he landed, he started collecting the dead bodies of people and brought them all towards the center of the valley, where The Saber Monarch is currently sitting along with the third family head.
Sam called Specter out and both of them started performing a large ritual of soul necromancy.
After Sam laid out an inscribed formation, he walked to the Saber monarch and the Third family head and gestured them to go inside the formation.
And then the ritual started.
