The Marquis of Han

Since you have such a grand vision and want to change so many things, why not change the protagonist to Liu Che (Emperor Wu of Han)? That would make it easier to change the Han Dynasty at that time, and readers wouldn't be so heartbroken; they would have far fewer concerns.

I want to write a book, a fantasy/sci-fi version of the Three Kingdoms period. The setting is after the reign of Emperor Guangwu (a time traveler), during the Industrial Revolution and the resurgence of spiritual energy. Guan Yu wears mechs and uses skills, Cao Cao commands tanks, Zhou Yu leads aircraft carriers and battleships, and the opponents are the entire Western Continent, including…

He only remembers the bad, not the good. The protagonist is doomed under such a person. To survive, he either needs to usurp their power or be stronger, otherwise, he's doomed. Speaking of which, the protagonist who transmigrated is far too docile. Being a warlord ruling the southeast would be better; with careful planning, he'd naturally grow stronger. Have you ever seen someone kneel before a monkey? A transmigrator kneeling before Liu Che... Haha.

During the reign of Emperor Wu of Han, with your abilities, your end was destined to be a tragedy.

It seems that in today's historical fiction, the protagonist can't survive without some kind of futuristic, cutting-edge technology. Ancient times lacked both intellectual property protection and a robust supply chain, so how could they possibly possess such advanced technology? Isn't it enough for the protagonist to know the future course of history?

I'm not going to comment anymore; saying too much will only make the author angry. Writing a novel is no easy task. Let's talk about the protagonist. He just transmigrated here and he can't get used to this or that. He can't eat minced meat and insists on improving his diet. He even modifies various cooking utensils in order to get some food! Honestly, kids these days are rarely this spoiled.

The protagonist is too arrogant and loves to teach others, thinking himself a saint. However, those who act as if they know everything in front of the emperor all end up dying tragically.

I remember that the Han Dynasty was suppressed and beaten by the Xiongnu for many years. The Han Dynasty only rose to prominence for a short time, and then it was still bullied by the Xiongnu. Compared with the Warring States period, it was really much weaker.

I've read a few chapters, and it doesn't feel as good as the previous one. It's better if it's about Japan. You could write about monkeys. The earlier parts were high-level, so you can start from the bottom. I definitely support that.

Did the Western Han Dynasty still adhere to Huangdi's governing philosophy? Without the threat and harassment of the Xiongnu, this approach would have been fine. However, the Xiongnu problem had to be solved. War against the Xiongnu required a massive concentration of manpower, resources, and funds, and it would be a protracted conflict, making centralized power essential. Without the pressure from the Xiongnu, Emperor Wu (Liu Che) would likely not have reached that point.
