Chương 177: Brother, how can you do this to me?!

Living Steel Gu is a Rank two Gu, looking like a charcoal briquette, fist-sized and black all over. On the surface, there were numerous holes.

Fang Yuan injected his primeval essence and this Living Steel Gu started floating, rotating on its own, black smoke pouring out from the holes on it.

Chainsaw Golden Centipede coiled around Fang Yuan's leg, its dark-gold colored armor full of injuries, the two rows of razors on its sides tattered and damaged.

But when the steel smoke came over and covered these wounds, they gradually healed.

The black smokey steel essence continued to be used, as the two rows of razors on the Chainsaw Golden Centipede could be seen growing at an observable rate.

Healing Gu varied in a few types. There were some that healed Gu Masters, some that specialised in certain injuries, and those that healed Gu worms.

To the Chainsaw Golden Centipede, the Living Steel Gu is its healing Gu worm.
