he could teach it to the good guys at least! why does he keep it just to himself!!!
but there are a few peope who were good and tried to hold up humanity in his last life, would'nt it be very important and helpful for them to survive? like that leader guy (lin i think?). as it stands i think it's very egotistical of him. it's not like other people are not evolving and it could give an edge to the people who care for humanit as a whole! right now it looks like he only care that his own group will survive.
hy would he not kill her if she knows that much? he looks like the kind that will get all the info he can from her then VANISH her for good. Just kill her when she can't give him more
But that would basically be killing the golden goose before it can even hatch you a few eggs. She knows a lot and obviously that's a security risk, but at the same time it can be a potential boon. If he manages to get on her good side or she manages to prove her worth, then keeping her alive could have far more benefits than killing her.
Plus, it's not like she's demanding all that much. Just a few months of playing fiance and he can gain access to all sorts of forbidden information. If anything he's benefiting more than she is.
Of course, she could be playing on what she knows of his character. From the looks of it, the ML seems like the type to "play with his food" so to speak. Perhaps she's playing on his innate sadism so as he is more willing to play along?
I don't really like them, and it seems that we will have one between the 2 princes and her... sigh
But really what is Mil doing, asking that of his futur sister in law?!
