The affectionate "little witch" chose to drink poison to stop him from dying. Why didn't he stop him?

There is a deep affection between Guo Deyou, the river god, and the little witch in the play. Why didn't Guo Deyou watch the little witch drink the poison? In fact, he has a plan. Guo Deyou, the river god, has changed the poison. The poison is nontoxic, so the little witch didn't stop her when she drank it. Secondly, Guo Deyou, the river god, in order to gain the trust of the ancient Taoist priest, showed the ancient Taoist priest that he was willing to join them and give up his beloved by drinking the poison of the little witch. Let the leader of the magic ancient road fully trust Guo Deyou, the river god, and think that he really joined.

The little witch drinks poison for the next plot development. If Guo Deyou, the river god, can't get the trust of the ancient Taoist priest, there will be no next plot. This is an important turning point in the play. Only after the little witch drank the poison and made Guo Deyou, the river god, gain the trust of the ancient magic road, did Guo Deyou have a chance to go undercover in the ancient magic road and stop its recovery. The magic ancient road is a cult organization, and the river god did this for the people, so as not to let the magic ancient road continue to harm the world.

The little witch drank the poison and looked at the river god with tearful eyes. This expression of disappointment and heartbreak is very real, and it is easy for the leader of the ancient magic road to trust, and it is also easy for Guo Deyou, the little black god, to go undercover in the ancient magic road smoothly.

I think the image of Guo Deyou, the river god in the play, is relatively tall. He has a just and kind heart, hoping to save more people and prevent them from being hurt by the magical ancient road. It is precisely because he has people in his heart that he has the responsibility to save them. Even if he has no intention to save the little witch, he will give up trying to save her. The river god has his reasons for not stopping the little witch from drinking poison.
