The king's tribulation was the ceiling for the cultivators in Yin-Yang World and the Water-Wood World, as well as in the cage.
In the entire cage, Han Fei estimated that there was no second king realm powerhouse except Zhao Xianglong, who was already a lunatic and was still sealed.
Therefore, whoever became a king would be the master of this cage.
The Half-Kings could basically trigger the king's tribulation.
However, it could only be triggered! Usually, before their lives were over, they wouldn't rashly transcend the tribulation.
After all, in the history of the cage, no one had ever successfully transcended the king's tribulation.
How many Half-Kings had died under the king's tribulation? It was not like they didn't know. Therefore, unless it was absolutely necessary, no Half-Kings would rashly try to transcend the king's tribulation.
But now, under Han Fei's pressure, Jin Changhai chose to transcend the King's Tribulation.
