Mc is wise and not stupid to overexpose himself to the world with super new and super strange for others, except for people who have experienced modern sciety.

Add harem. Every versatile mage fan fiction should have a harem tag added. Star rating would be higher if the MC didn't take all the women into his harem, even the original protagonist's wife. Mc already has a system, but it still takes away all the opportunities the original protagonist had.

Missing chapters...

Low score mainly because I personally don't like fate/destiny controlling the MC.

Slow burn. Very slow. Exchange technology for something intangible, it's okay to exchange tech with the government, but it has to be for something tangible. It's the early 2000s, and he's jumped from engines to drones to space shuttles. That is a very big logical loophole. I personally can't get by based on the "modern" setting the author has written.

I dont like how the mc got his "system".

It was okay but MC is a SYSTEM TASK SLAVE.

It feels like the author just picked 10 different genres and mixed them together when writing this novel. Too many things are happening, and it gets distracting and confusing.

Only 3 stars because the system disappeared or the author forgot about the system halfway through the novel.
