As a reborn figure with his own system, Gu Feixian never thought about conquering the world, becoming a king on his own, etc. The greatest significance of his existence is to become the protagonist's mysterious golden finger. If the protagonist wants to ascend the throne and become king, he will be the former emperor's master, and then turn into a rebellious minister who will be killed by the protagonist's overlord. If the protagonist is the leader of the righteous path, he will be his former fellow disciple, and then an important figure in the opposite demon sect who did many evil things and died under the sword of the protagonist sooner or later. Gu Feixian, who had been mentally prepared, unexpectedly discovered that his lovely brother was the protagonist. Gu Feixian: I want to cry, really. (The younger brother is not the official spouse)
