Because the author is a virgin who would simp over any pretty girl paying him any attention and the novel is his wish fulfillment fantasy?

Mask? Psychopath? True nature? Nah, He's just a normal human, the so called "human conscience and morality" is a social construct, which is also what tend to create rifts between different cultures, so not caring about if parents or other people die is actually human nature as it doesn't grant any benefit to survival to be sad, of course, if you build a bond with someone you can get sad when they die, but that again is a social construct, since if you didn't build a bond, you would have no reason to be sad, which goes for both family and friends, at the same times he shows various signs of depression, which in itself can lead to a state of apathy, so yeah, that true nature of his is nothing special or out of the normal

That has nothing to do with China being good tho, it has to do with capitalism, most western companies have their Mass produced products, be it clothes, furniture, trinkets and so on produced in China due to the cheap labor, and not to mention much lesser safety in regards to workers, letting you save tons of money in that regard too, not to mention that while child labor technically has become illegal, due to human rights groups, it's still quite common there, due to poverty, but doubt you'll hear that in many chinese novels, which might also be due to them not knowing the actual situation of their own country as their internet is over 90% censored, China is on par with North Korea when it comes to keeping the population ignorant.

Would suggest correcting the names and pronouns, unless Hades suffer from multiple personality disorder, is both a guy and girl while ordering himself around

Wow... Such betrayal he suffered, a kids scuffle vs. Friend trying to kill you... Yup definitely the same... Lost the concept of friendship, yet first thought is wanting to be friends with the dragon?... Yeah makes sense, or not... Hope it gets better

... Funny, short Google search shows cyberbullying is over 3 times worse in China than Japan, so please stop with the shitty nationalism, people don't enjoy reading it... Sure, say the character loves his country and people and wants to protect them, but for gods sake stop using that distorted nationalistic bs with no basis in facts... It's sickening

I'm curious now that I've seen several novels claim China as being the safest country in the world, yet if you Google a ranking for the safest countries in the world, you'll find Iceland as the safest country in the world for 12 years in a row, while China isn't even in the top 10, and no im not from Iceland, my country is ranked 5th on the list of safest countries tho, so guess it has room for improvement, but in general I dislike nationalisme and blind faith in ones own country, afterall if you divider everything into "us" And "them" there will only continue to be war and suffering in the world.

I like the story concept, but really puts me off that he basically built a big city in 3-4 months, since... Yeah... Even just his own house being finished within that time wouldn't be realistic, so even more and bigger building projects even less so... Even considering the people having above average strength it's still not feasible for them to build something 10 or more times faster than modern building companies can, since the increased strength doesn't make up for earths technology and convinience. Considering they have ways to prolong life to an unknown degree, I would have loved to see the author slow the pace and spread it out over a span of years, afterall the main character is young and can even extend his lifespan, making it a shame to see an action novel pace in a world building novel. Otherwise keep up the good work author, and you are doing well for a first novel and I hope you continue to grow and improve as an author.
