According to what Morbius had just said, it was possible not to waste the spirit qi in the spirit qi crystal when using one to enhance five to six Bronze/Epic feys to Legend.
Lin Yuan would not need five days to do that in the future. This would undoubtedly save him a lot of time.
He had not really thought about using the spirit qi crystal formed by Morbius' Spirit Qi Condensation to enhance the Bronze feys' quality.
When the spirit qi crystal was crushed, it would turn into a huge amount of pure spirit qi. If Lin Yuan controlled such spirit qi and used it on several feys, a part of the spirit qi would undoubtedly be lost and result in waste.
Every single trace of the huge amount of pure spirit qi in this spirit qi crystal wasted was akin to wasting Lin Yuan's time. At the same time, it was also wasting Radiance dollars and resources because the overflowing spirit qi could easily nurture many Bronze/Epic feys.
