Noah and the others had created an excellent story to justify their divine items while preventing the other organizations from sending other teams in the Odrea country. They had revealed the existence of a separate dimension under the Mausoleum, and they had described it as an inheritance ground that tried to imitate the Immortal Lands.
Their story fit what the world knew about the god of the Empire and even explained why they had gained access to divine items when they were only rank 5 cultivators.
According to that lie, the group would have slowly explored that foreign land filled with dangers in the last five years. Yet, when they reached the rewards, they triggered a reaction in the separate dimension.
The inheritance ground detonated, and the void enveloped its entire space. It was only due to the group's careful approach that the cultivators had managed to return to the outside world in time while also seizing the divine items.
