The cooldown period for the Emperor's Treasury is unknown to outsiders.

However, according to rumors from the High Heavens, Emperor Qin rarely uses this ability. There was even a time when someone killed Emperor Qin, and he didn't use this ability, indicating that it was likely on cooldown at the time.

It's estimated that this cooldown lasts at least twenty years.

Undoubtedly, the combat power of the Emperor's Treasury is extremely terrifying.
