Review Detail of OVERKILL in Catastrophic Cultivation!

i was hoping for some cultivation stuff, getting stronger slowly but i didn't see it. first chapter gave me hope for a reincarnation , system , and cultivation. but i have read almost 15 chapters i can't find any of that . what i found is that there are TWO MC, a male and a female . both have a system ( that wasn't mentioned in details , no lvl ups , no quest , just weird reward ) . things shifts around like devil fruit , mobile phone building a gundom , marriage , girls . male MC is some how top tier ruin master ( not explained at all , just author said it you believe it , no progression from start , no build up nothing ) then MC make some kind of nuke. random bullsh¡t is flying every where and you have to make sense out of it . both MC are bickering to each other in every single chapter . and this bickering is the main story i guess . Ward background : -- ZERO CULTIVATION REALM. : - ZERO explaination CHARACTER - two mc with systems , that it .SYSTEM - author didn't care about it , it helps the plot to progress in very rare ocacasions. and pretty much a click Bait .
