Red Boy's father, maybe someone else?
The ancients often used the method of blood identification to distinguish relatives. In modern times, people use DNA. Then, how should we distinguish whether it is a biological father and son in the demon world?
In the Journey to the West, a father and son had problems. Some people speculated that the red boy was not the biological son of Bull Demon King.
Proof 1: the appearance of Red Boy and the Bull Demon King is different. The Bull Demon King has two horns on his head, which looks ferocious. On the contrary, the red boy has only two little braids on his head. Even if the Bull Demon King and Princess Iron Fan are genetically neutralized, it should not completely erase the genes of the old bull.
Proof 2: the Bull Demon King has a lot of killing magic. Even the cooperation between Sun Wukong and Zhu Bajie didn't beat him down. Moreover, he is also proficient in 72 changes. Such an expert can make outstanding achievements if he takes an apprentice, let alone teaches it to his son. However, Red Boy didn't learn some of his skills but discovered the samadhi true fire of others.
But are the ideas above really true?
First of all, the appearance of the red boy and his father. In the original book, Bull Demon King's appearance is as follows: One eye is as bright as a mirror, and two eyebrows are as bright as red neon. The mouth is like a blood basin; the teeth are arranged in copper plates.
Therefore, the two horns on his head don't need to be exposed all day. Many immortals or demons can hide their true bodies after cultivating to a certain level, and the Bull Demon King is no exception.
Then there is the magic of the Bull Demon King. The red boy is still young, only more than 300 years old. He is still a child in the demon world. He has unlimited possibilities for the future. If the Bull Demon King wants to let Red Boy inherit his career, he has much time to do that. And the red boy needs to learn according to his interests and hobbies.
Therefore, the red boy is the son of the Bull Demon King. As for the rumor that Lord Lao Zi has something to do with Princess Iron Fan, it's also not true because the banana fans in their hands are two banana leaves on a banana tree. They are not the same at all. They belong to Yin and Yang. Lord Lao Zi has not given others banana fans.
Finally, after losing her son and husband, Princess Iron Fan studied and practiced hard. One day, the three of her family were reunited in Ling Mountain.
