Find an old zombie movie.

What you said is very similar to two zombie movies. In the first step, Uncle Ying's masterpiece "Mr. Zombie" tells that Mr. Ren was buried in a dragonfly water cave, but 20 years later, because Ren's family didn't get the benefits of the dragonfly water cave at all, the coffin was moved! Because the coffin was not handled in time, Ren became a zombie and brought disaster to Renjiazhuang! (Very funny, worth seeing) The second part is the zombie revival, the representative work of Mr. Yuan Wah. Although it is a series, it is also very good! Among them, Ren Bo is the lone star of Dreadwind. In order to get the position of mayor, his father Ren Bo was buried in the cave of Toad Moon. This cave can bring great benefits to future generations, but it also has disadvantages. If it thunders and thunders to the grave, the people inside will become super invincible zombies! Very nice. Go and have a look!
