Brown Bear Strength Gu

In Shang clan city, Fang Yuan cannot buy Bitter Strength Gu, so he attempts to refine it himself. ^{ch. 304}

Loss in refinement

The success rate for refining Bitter Strength Gu is very low. Counting a fourth failed fusion, Fang Yuan has already lost Brown Bear Strength Gu along with galloping horse strength Gu, Green Bull Labor Gu, and Stone Turtle Strength Gu, plus precious supplementary materials and large amounts of primeval stones. ^{ch. 304}
