In a Crossover World, Can Believing in the Machine Spirit Help Me Beat Impostors with Elbow Strikes?

Did Shennong exist?

The tag indicates multiple heroines, so what's the point of keeping Hachiman Hikigaya?

Sometimes I feel this worldview is quite abstract. I wonder, if we went back to China, would there really still be collaborators and traitors among the armed forces? And if guns could eliminate all the collaborators in various places, could we really survive?

Seriously, are there some problems with these characters in the story? They're constantly being invaded by fake humans, yet they still have the leisure to let the protagonist go out and play?

Basically, it's a fictional character created by forcibly adding a pseudo-human element to a realistic scenario. Many things can't be considered in detail. Ordinary people are like pure NPCs, only appearing when needed. When not needed, even if someone is firing wildly in a residential building, the entire building will remain deathly silent, and no one will react.

I have a question. I've read up to chapter 14 and I don't quite understand. How could Jing Ke'ai let those three little brats investigate something so dangerous? She knew it was dangerous, but now she's not doing anything about it. But when the male lead did something dangerous, he intervened. It's a bit shameless of her to push the plot forward.

Having read up to chapter 237, where the protagonist wants to buy land and start a fortress-like enterprise, I started to feel uneasy. Frankly, I don't want to read anything without a female lead. If I wanted to read about simple monster-fighting or making money by starting a company, I'd find a fantasy, magical realism, or urban fiction novel. Why would I choose a crossover anime/manga novel? I read crossover anime/manga novels to see the protagonist and the female leads' daily or extraordinary moments, and all the plot points should serve as a backdrop. Up to this point, the text dedicated to the protagonist's homemade gadgets and fighting fake characters far outweighs the text about the female leads. And this is a multi-female lead novel, so the screen time for each female lead is even less. A large portion of the text focuses on fire control, assembling drones, and other hardcore stuff that I don't understand and don't want to read.

The protagonist was quite cautious at first, but when they went on a trip to Izu, he became like a fake. Firstly, there was a radio in the hotel room that kept announcing itself in a strange and uncanny way, but I didn't pay it any mind. The second time I went in, something happened, so I told the front desk. They said it was resolved, but they didn't change my room. I checked back in that night, and they didn't ask anyone to gather and discuss whether we should change hotels or leave the area. They didn't even ask us to stay with them that night to avoid any accidents. The third time the bed was found to be faulty, a message was sent to warn others to be careful, but no one was asked to gather together or suspect that there was something wrong with the hotel.

The theme is quite novel, so some minor flaws are tolerable. However, it gets a bit bland starting from the point where the company is set up. Also, I have a personal complaint about urban fantasy fanfiction: are the characters from *My Teen Romantic Comedy SNAFU* and *Saekano: How to Raise a Boring Girlfriend* essential characters in urban fantasy fanfiction? It feels like current urban fiction is inseparable from characters from these two works…

Is there a CCB (Converted Cash Flow) step?
