Yes it is. But the manga is just for the fun of it, sometimes the author gives the manga different script to draw on. Others will follow some part of the novel. It's just for the laugh better artist greater the laugh. This manhua is the best example of the difference between best artist and a good artist. First part it it was great, but they just have to change the different artist in the middle, now is not so great (/TДT)/
