I made a ghost movie, why did I become a heavenly master?

As an atheist, Lin Zheng travels to a strange world.
Made several classic zombie movies.
But did not expect.
There are really zombies, weirdness, and monsters in this world!
At the same time, some people who can see the weirdness discovered it.
The method in Lin Zheng's movie actually dealt with these monsters, ghosts and monsters!
Black dog blood, peach wood sword, immortality amulet...
Lin Zheng failed to become a famous director, but became a globally recognized ghost hunter.
Lin Zheng, whose yin and yang eyes hadn't been opened yet, looked bewildered:
"I'm really not a celestial master, there are no ghosts in the world, we must believe in science!"
(Note: The protagonist does not believe in ghosts from the beginning to the end, he will gradually discover, believe, and accept.)
