well... I have read 400 chapters and the only thing I can say is what a magnificent novel, I fully recommend it, there is no extreme nationalism like other stories, a moderate one that I like, it is not the typical story that says that China is the best country in the world, shows its defects perfectly. The MC is also one of the best written, he is someone 47 years old who returns to his 21 but it is not the typical thing that seems to be that age, it shows the maturity that he has, he worked as an aviation engineer and shows that experience that he has , although there is a system, but practically it is a plus, even without that he would make a name thanks to his experience. The defects: there is a lot of technical information that ugh, that surprises me, the author did such exhaustive research or is he a real engineer, the other thing I don't like is that it is quite slow with the 400 that I have read, it has only passed 1 year and 7 months, but it is because the story is so good that the chapters fly by, the most likely thing is that the story has more than 5k chapters, that is why I will leave it here so that they accumulate. Something that I had not liked is that the MC was very young at that time because he was practically a man at this time, but then I remembered that Elon Musk is 52 years old and the MC would be younger in this year (2024), practically it could be the Chinese elon musk and I loved it, the author can practically finish it in the year 2046/56 with the MC being 70/80 years old respectively, but it would be too much to ask, who knows in what year the author would finish it. I hope new readers read it, but yes, it doesn't happen to them like me who got hooked when it still didn't have enough chapters.
