A shapeless white jade represented Roar of a Windy Day. Gray could summon a wind-covered horse from it.
At that moment, a yellow snake-species fey with thunder crackling all around it appeared on Gray.
Just as Lin Yuan was about to ask Gray why it was not summoning the jade beast, Gray said in a childlike voice, "Yuan, replenish some of my spirit qi. Otherwise, I won't be able to activate the rainbow weather gem."
Lin Yuan found this strange.
Although Gray had used up a significant amount of spirit qi to fuse the abilities, only a minute had passed. As such, Gray should still have at least 4/5 of its spirit qi left.
Gray also did not require a lot of spirit qi to summon the snake-species fey.
Could it be that the rainbow weather's elemental lifeform was special?
Lin Yuan lifted his hand and used Spirit Injection on Gray. Soon after, Gray was brimming with spirit qi again.
