Girls Are Cute
MC can sign in once per day. You’re telling me on this day, only this day, for some reason he didn’t use his sign in chance today and waited until he went to help his nephew with the nightmares, then coincidentally he was able to suddenly sign in at the Empress palace and get a skill that happens to allow him guaranteed victory. Author’s completely given up on hiding him forcing the plot. In the past he would at least claim that MC’s able to sign in suddenly before/during a battle due to the day just ending.
