The end of the world is coming, I have many children and am blessed

Su Yang traveled through the world of anime and originally planned to be a plagiarist to earn his first pot of gold. However, a week after school started, he ran into Saeko Busujima!
Just when Su Yang was wondering what to do, the system of having many children and many blessings was bound!
As long as the pregnancy and childbirth are successful, rewards will be issued!
[Kasumigaoka Utaha: Evil scum, you imprisoned me for a week and you don’t plan to tell me who you are? ]
[Sakurajima Mai: Did you also subconsciously forget that I was imprisoned? ]
[Yukinoshita Yukino: I set up the service department, not to serve your children! ]
