The Isekai Milf harem! - Chapter 17: Ch) Sixsome - Creampie.

A tale about the former leader of a special organization that served under royalty, now leaving his past life behind and unintentionally getting involved with the martial world.

There’s nothing that Yu Wan has in common with her new neighbor– whether it’s charisma, personality, or cooking skills– other than that they both own dogs. Their two cute pets get along well (a bit far too well) and start what seems like a rocky friendship between the two; however, Yu Wan has more important things to worry about. Her wildly popular novel is about to take off into a drama adaptation, but the handsome, mysterious, and callous neighbor- is the director?!

Shen Qingzhou (as he thinks of someone): I’d say three. ]

When the system warned the world that it was coming a week in advance, Alex couldn’t have been more excited. In college for a degree he didn’t care about to get a job he didn’t want, the promise of a world where magic and challenge awaited — even at the potential cost of death — was the best news he possibly could have imagined. Alex was ready for a new life. He ready for his only friend to shove him through a portal into hell the moment the apocalypse started. Instead of getting to punt rabbits and farm wolves, Alex finds himself stranded in a warped world where even the bugs are stronger than he is. Even with a summoner class that gains the powers of its monsters, most people would have died. Alex didn’t get the memo. He might have liked challenge a little bit too much. Where others saw certain death, he found something else. Opportunity.

The protagonist, Punk, is a cautious, cold-blooded, and ruthless Mage.
