If I Wasn't a Programmer, How Could I Catch Ghosts?

I am 28 years old. After graduating from college, I have been working as a programmer in a second-tier factory. Life was going as planned until my childhood master, a Taoist priest who always appeared and eluded me, suddenly appeared in my world again, completely overturning my daily life. I thought he was asking me to help fix his computer, or at least troubleshoot some network issues. As a result, when I put down the code at hand and rushed to the designated location, I discovered that this task was more difficult than any bug - I had to use my "skills" that had been dusted for many years to catch a real ghost.
