Lightning Tribulation

"Look, the clouds above the tribe leader's house," One of the tribesmen pointed at the looming clouds.

"They don't seem like normal clouds," another tribesman raised his brows for a moment and continued, "I remember now, they are tribulation clouds."

"Tribulation clouds? What are they, head?"

Many of the tribesmen looked at him and asked their head of the unit.

"I once read in the history books of our tribe that when anyone reaches the top realm in the five elemental world, they have to cross the lightning sent by those clouds. Those clouds are called lightning clouds where the process is called 'Tribulation'," The head of the small construction unit explained about tribulation to his squad.

The lightning tribulations were different in every world and the power from the lightning differs with each person. The more powerful the individual was, then the stronger the tribulation would be.
