Universe needed its wings and tail to swim in the air. It was like how pedestrians needed to swing their arms when walking.
Every time its wings and tail moved, the pure spirit qi on Universe's back would be replenished.
If the lifeforms on Universe's back used up spirit qi slower than the rate at which the spirit qi on Universe's back was replenished, the amount of spirit qi on Universe's back would increase continuously.
As a result, Universe would turn into a spirit qi collector. It would be like a blessed site.
Suddenly, Lin Yuan wondered if all the spirit qi in the main world would eventually disappear and be located on Universe's back as Universe's power continued to increase and filter out spirit qi.
If that were the case, he would be committing a serious crime!
But regardless, with Lashing Spirit Tail Wings, Lin Yuan would never have to worry about preparing resources again.
