Xu Jiao has transmigrated. Here's the situation: the Sheng Kingdom is under attack from enemy nations, and the war is raging. Her husband has been conscripted, and she has no idea which battlefield he's been sent to. At home, the drought is severe. The village river has dried up, the wells have run dry, and they are on the verge of fleeing famine. To make matters worse, she's pregnant. The one bit of good news is that her parents-in-law are kind, reasonable, capable, and genuinely care for her.
