Where did you get this key?

Of course, to the Gu family, 10 billion spiritual stones was nothing.

However, if they were exchanged for 100 sea of consciousness tier extreme grade precious artifacts, the meaning would be completely different!

With these 100 supreme class precious artifacts, the Gu clan could almost double the number of demon suppression guards!

This was because these sea of consciousness extreme state precious artifacts could be combined with low-grade extreme state precious artifacts.

If one was paired with a few tribulation passing or even spirit forging stage treasures, the overall defensive power would not be any weaker than the current set of treasures that the demon suppression guards were equipped with.

In this way, the profits that could be brought to the Gu family would be at least several times more than the value of ten billion spiritual stones.

Even the Gu family could not ignore such a huge amount of resources.
