Review Detail of CH405Kaiser in Xianxia: Why am I here?

I have no idea what is really going on after reading the first 5 chapters. MC is thrust into a martial art world where he is forced into arrange marriage. From there, he needs to practice some kind of martial art to increase his body strength but it doesn’t really mention what martial art and how he gains points to increase his potential value. Author does not explain nor does he refer to physical strength until chapter 4 or 5 that attribute points is physical strength. All this time I thought it was him accomplishing small achievements in martial arts and then he could use the attribute points to strengthen his potential. There isn’t much world building nor characterization.
