Just After Crossing into Another World, the Queen and I Were Surrounded by Rebels.

As a good young man in the 21st century, he was suddenly transported to another world inexplicably, and he also brought an industrial system with him. What's even worse is that as soon as I traveled through time, I learned that the nobles led troops to rebel and surrounded the royal capital, and then I looked at Her Majesty the Queen, who was nearly nine years old... PS: For empire-type novels, the background of the novel is generally a pure Western fantasy type. There are not only orcs, elves, but also dragons and the like. The protagonist's industrial system can develop technology by climbing the technology tree. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
