Dangerous Shadows

Author, are you sure the protagonist traveled back in time? He even stayed in Unit 76 for quite some time. Are you sure the protagonist isn't a complete novice?

The spy drama is written too childishly.

Criminal police officers used to have mind-reading abilities, but their mental fortitude was still worse than that of ordinary people.

After reading a few chapters, I feel that given the protagonist's behavior at that time, he should have been completely finished.

The protagonist has too many flaws, and the writing is too simplistic.

It's clear the author tried their best and was very serious. But reality is cruel; many things don't pay off just because you try. And that's not something to regret or pity. Keep going, all I can do is offer my best wishes. Additionally: The male protagonist falls in love with a Japanese woman (1234) and has witnessed how this woman slaughters (1234) his comrades. No matter how much he struggles and agonizes inside, it doesn't seem like an excuse for him.

There are too many loopholes; they really won't survive past the first episode.

I don't understand why the author wrote the protagonist's past life as a narcotics officer? Would a narcotics officer behave like this? This is completely like an ordinary citizen.

Good heavens, how did the author manage to write about places like No. 76 And the Japanese Special Higher Police as if it were a joke?

Overall, it's alright, but the key is a more compelling plot. The protagonist's "golden finger" (advantage/power) is too weak. It needs to be about using small resources to achieve big gains—wealth, status, and power.
