After Being Summoned by the Elf Girl

My name is Yiming, and I was just summoned to a different world by a beautiful white-haired elf girl. But there seems to be something wrong with my cheat card [card summoning system] - the first task at the beginning actually asked me to "solve" the dying summoner? Is this system a little too rebellious? Now, I have rescued her, but she has lost her memory because of my summoning technique, and can only look at me with innocent eyes. The most important thing is that the system is also on strike! I just want to quietly upgrade with this beautiful "trouble" and solve the mystery of the system strike. But why do I always feel that she hides a secret more terrifying than the ultimate BOSS in this world... [Level-up flow] [No system] [Single female protagonist] [Relaxed and humorous] [No sword]
