Beast Fetus Gu

In his room, Fang Yuan takes out the strength of ten jun Gu, an iron weight that is heavy to carry. He had already used one kunlun bull strength Gu, and a second would have no effect and give no second beast phantom. Jun strength Gu has no such restriction and can be stacked until the body’s limit is reached. Similar beast strength Gu can be stacked as well, but an additional beast fetus Gu is needed to do so. ^{ch. 443}

Many different recipes of beast fetus Gu were passed down. The materials for refining it are very rare, the cost is too high, and its success rate is inferior to jun strength Gu, so it was eliminated in the competition. The text does not state a rank for beast fetus Gu, and the chapter does not describe the Gu worm’s look or food. ^{ch. 443}
