I love this so much. I've read hundreds of manhuas, and dropped them all sooner or later. None of them made me feel remotely like this. The plot is reasonably deep, the characters are very well portrayed, the art is on spot, the pacing is good, the science is true (enough), the references are amazing and the protagonist is very competent, yet feels human. It just balances everything so well, the humor, the drama, the action, the nostalgia... It's the kind of thing that gives me awe, makes me wonder how people can be so talented to get so close to perfection (especially when there's such a huge volume of competing crap).
