Liu Changan traveled to the Qingluan Kingdom, a country where wars and natural disasters were constant. His family was destitute and they only relied on wild vegetable soup for three days. When his eldest brother Liu Changshou was dying, he asked his sister-in-law Lin Wanru to starve to death. Liu Changan couldn't bear it. At this time, the "Heart System" is activated and bound to Lin Wanru, and the system can draw prizes based on the heart value. In order to save her twin sisters from a brothel, Lin Wanru asked Liu Changan to marry her. Liu Changan won thirty years of archery skills through a lottery. In order to provide Lin Wanru with meat, he went hunting at the foot of the mountain with his bow and arrows on his back, and thus began his journey to survive in troubled times.
