The lightning tribulation realm comprised the three tribulations of heaven, earth, and human!
Only by passing through these three lightning tribulations could one advance to the King realm that could dominate the world. Only by breaking through to the King realm could one truly wrest one's fate from the heavens.
During the pattern condensation realm and the lightning tribulation realms, one had to be wary of the karma of the heavens. Failure to do so would lead to a more difficult tribulation, and the cultivator may not even be able to advance to the lightning tribulation realm, much less the king realm.
Hence, before breaking through to the lightning tribulation realm, most pattern condensation realm cultivators would choose to stay clear of matters that might affect their own karma. In fact, within the Huangyu Zone, there were many pattern condensation realm and lightning tribulation realm experts.
