The opening of the Qiankun Mansion aimed to produce more Sixth Stage Rule Integration Realm experts among the human race, and these additional experts were ultimately meant to provide sufficient power to the Qiankun Cauldron.
Therefore, the extent of resonance with the Qiankun Cauldron ultimately determined how much power one could provide it. The higher the resonance, the greater the power one could supply.
The Qiankun Cauldron was forged by the Human Emperor and was not found elsewhere. As a result, every human had a resonance with the Qiankun Cauldron, with only the degree of resonance differing.
Resonance levels were divided into four tiers: Low, Medium, High, and Supreme.
A higher resonance level not only allowed one to provide more power to the Qiankun Cauldron in the future but also granted access to more hidden resources within the Qiankun Mansion at present.
