It's said that the seven tribulations appear sequentially, but in fact, they occur simultaneously. The first to manifest its power is the "Prison Tribulation."
This tribulation is extremely rare, embodying all the sealing methods between the upper and lower realms. Once it appears, it will completely immobilize the cultivator, rendering them unable to respond and making their cultivation and magic treasure useless. In such situations, they can only rely on the protectors and friends they've enlisted for help. But who would risk their lives to resist the heavenly tribulation?
So when the Prison Tribulation appears, it's the worst news for the cultivator undergoing tribulation, almost a certain death sentence. Under normal circumstances, among a hundred cultivators undergoing tribulation, not even one Prison Tribulation might appear.
