Exhaustion

The days passed with the flow of time, mornings came, and evenings went, and soon a month had passed.

During this month, Xue Wei had only been back to talk with his friends a few times, other than that; he had been busy mutating beasts.

One of them had died, but the other nine had survived. The one who had died was a young female. Her death was not due to lack of willpower, but because of Xue Wei being stronger than her, and the blood being too overbearing, simply killing her within a moment.

After this, the Retired Emperor made a selection of who to use the blood on. He no longer picked weaker experts; only those who were at the Earth and Sky Saint Realm were able to withstand the powerful mutation process.

As to how Hei Gou had done so, it was truly a wonder, and Xue Wei finally understood that the pain his good friend had been under was much worse than any of these beasts'.
