Started watching Detective Conan again after almost 2 years

I stopped watching after moving to a new place and not setting up cable TV. Before that, I used to watch one episode a day on CTS. I'm planning to start watching again from episode 500-something. Today I reached episode 514. So many plot points are unreasonable. For example, the places Conan hides are always exaggerated, and it's like everyone is blind. Also, some of the methods aren't fully explained, and it's all up to the audience's imagination. I can only say that my tolerance two years ago was really high; I completely ignored the unreasonable parts. I'm so curious about how it ends. Could it be that Gin is also an undercover agent? I saw someone suggest this, and after reading it, I thought it was quite reasonable lol. (Please do not reply with 'Thanks for sharing' or unrelated text.)
