Gu Masters are the most troublesome people in this world. Once you provoke one, unless you kill them in one fell swoop, you will live in crisis at every moment. Even when drinking water or eating, you must be fully alert. A moment's carelessness may result in being afflicted by a Gu, a fate worse than death.
Especially those Gu Masters who refine Gu using living humans have surely dark hearts, hold grudges, and every Gu worm has a special connection with its master. If a Gu worm dies, the Gu Master will certainly know and will definitely seek revenge on the killer.
In this regard, Lu Tianxing had no doubt. How much magnanimity can you expect from a Gu Master who refines Gu with living people?
