My Wife and I Guard This Place. How Dare You Act Outrageously?

[An extremely slow-burn story] [Multiple protagonists, both male and female, but rest assured: each protagonist has only one heroine or hero.]

[It would be impossible for every protagonist to have no heroine or hero. Please don't start reading and then come to the author to argue about it. After all, I designed the protagonists to be geniuses and strong people. Do you really think the country would stop the Matchmaker from finding partners for all these children with such outstanding genes?]

[This book also features spiritual-energy technology, along with all kinds of bizarre items created by combining the supernatural with technology.]
