to give this story 6 stars would mean that each star is an exponential growth in quality.
This story is really bad, the characters have no personality and the plot changes way too abruptly, like in the majority of Chinese stories I've seen so far.
To be realistic, Chinese manhua stories are mostly of poor quality, it's pointless to expect something good, but you cannot rate this anywhere near 6 stars unless you want to make it seem way better than it is, objectively speaking this has at most the capacity for 3 to 4 stars.
