Why does the curse mark appear on the fat man's back in the ancient city of Hu Bayi?

Hu Bayi went to the countryside and came to Ganggangyingzi on the border between China and Mongolia. He carries with him the only book left at home, The Sixteen-character Yin-Yang Fengshui Jiejing, and whenever he has time, he memorizes the words in the book. Later he joined the army and went to Tibet. When he met an avalanche and fell into a huge trench, Hu Bayi escaped secretly with his own grave. After demobilization, Hu Bayi and his good friend Wang Pangzi (Zhao Da) joined an archaeological team and went to Xinjiang for archaeology. A group of people went through hardships and dangers to the ruins of the ancient city in the Taklimakan desert and entered the underground "ghost hole". There are many organs and traps in the cave. This mysterious ghost cave seems to be controlled by a prophet.

It is reported that the eyeball-shaped curse marks on the backs of Hu Bayi and Yang Ping are actually symbols of ancient magic kingdom sacrifices. It is more likely to be a virus infected through the eyeball and the visual center of the brain. After being infected with the virus, there will be iron deficiency, and the blood in the body will gradually turn yellow and stop flowing. Finally, he died. Before he died, the high priest gouged out his eyes and sacrificed them with snake bones. Then feed the rest to the believers. Of course, the curse can be lifted by reverse sacrifice. "
