It'll be awkward with former wife if he ends up killing her dad prematurely. She will become his enemy, not his lover.

No One will come? Are you sure?

why does the dude keep the item in the open ... seriously, he reincarnated to avoid past mistakes but does new simple ones

This is a Chinese donghua.

The plot can't continue if MC doesn't offend powerhouses or if he stays low key.

If you want a donghua with a realistic plot, you should try "A Record of a Mortal's Journey to Immortality."

Yeah i have even read the manhwa and i love it. There are several more topnotch manhuas donghuas.
However, i cant hide my disappointment with these stupid ass plots, so i have always talk about the obvious. I cant turn my brain off anymore. However, so far this donghua proved to be better storywise just poor in quality
