Rape Warning!!- Just wanted to start out with that as it doesn't appear to be in the tags or many of the reviews, yet is one of the core components of this story.
The worlds the MC travels through all seem take the lawlessness of xianxia worlds and turn it up twenty or thirty notches - all of which is focused on rape.
Beyond rape, it is also worth noting that there are no real laws in any of the worlds and kidnapping, attempted murder, etc... are common place regardless of how out of tune it might be with the setting.
Aside from all that however, it is funny quite often and is essentially filled with 30-50 chapter arcs, each of which cover 6-8 volumes of some other comparable story. This does mean the story is rushed quite often and skips from the introduction of an idea to when it is entirely over instantly. (e.g. MC is given a challenge to earn money, MC starts a company in the same chapter, and has completed the goal in the next chapter after a time skip)
It is quite a good read if you can skim over the 10-15% of the novel related to rape.
