What's the name of the movie in which Yuan Wah plays the wizard making zombies have sex?

It is said that Nanmao and Ma Bei, the corpse drivers, are guarding a group of zombies. A man and a woman, Wang Zheng and Jinlian, who were originally a couple, were poisoned.

King-Tan Yuen plays Ma Xiaoling.

The case originally involved a secret letter from the emperor. The wizard Harajo (Yuan Wah) orders his men to find out the whereabouts of the secret letter of the dead man's head. (King-Tan Yuen) and Professor Mao () have always been at odds, bickering and fighting on the way to catch the corpse, and then they gradually fell in love. Nanmao's apprentice Lei Zhenzi (Gallen Lo) and Ma Bei's adopted daughter Tianji (Kathy Zhou) fell in love at first sight. Lei Zhenzi mistakenly used the method of poison under Hara's desk. Thanks to Tian Ji and others, she accidentally had a relationship with Jin Tianyi, and she was taken good care of during her illness. King Harajo and Jinlian gave birth to a strange baby. According to the secret book of mixed elements, the birth of strange babies will bring disaster to mankind. At this point, Tian Ji and Sadako decided to resurrect and save Shu Ren. What secrets are hidden in the secret letter? Can everyone successfully slay the demon and get rid of it? What should they do? I think Mr. Zombie's movie is very good,
