A stupid story good drawn. <-- For the TL;DR folks here.
First: It's got axed, so the "ending" is mediocre at best.
Second: This is not(!) a historical work at all. Yes, the author knows the correct spelling of the word Europe and know that 1099 the Crusaders conquered Jerusalem, but that's all. As far I know the Crusaders never had 90.000 fighter at all in their combined armies, let alone letting such a force march some 10.000-s of kilometre from Jerusalem to China. (I would like to see the faces of the Maharajas in India when the 90000 Crusaders got steam-rolling through India - "Sooorry! Just coming through."😉 And the Freemason, with their iconic sign, are first officially founded (the first Lodge) 1717 in England and not(!) before 1099. And many more points. It's a complete fiction based in around the year 1101.
Third: It's a Superhero/Supervillain comic. With flying Superhuman and the like. Nothing bad in it self, but Superhero Comics are not historical. And sadly there are only Chines Superheros/Supervillains, the Europeans are weak to useless weak. Well, no surprise here, a Chinese wrote this.
Fourth: This work have some really stupid scenes. The more the "story" unfolds the stupider it gets. I don't expect realism in Manga, but at least some consistency in drawing and storytelling. If you draw a plain than don't draw few panels later a deep gorge in the same spot. If you show and say that someone can't be killed under special conditions than don't kill him few pages later on, even if the condition still applies. OK, the Chinese are much better fighter than Europeans, I get it ... but that the Chines people can teleport in big numbers between Europe and China (the Europeans don't know it of course) AND know the deepest secrets of the Vatican (without any explanation and have some operating manuals ready for this secrets) is ... is something "little" over-the-top ... IMHO LoL. Fun fact: For long travels Chines are riding goats ... don't ask LoL.
I was deceived by the "historical" tag and the first 1-2 chapters were ... OK-ish. It's also not bad drawn. But latter on ... I wanted to see how stupid it gets .. plenty.
Don't waste time on this one.
