My Husband's Sweetheart Is a Time-Travelling Girl

The general returned from an expedition and brought back a woman named Lin Wan. He heard that the woman had drawn something called a pistol, which was so powerful that her husband turned defeat into victory and returned home in triumph. He couldn't bear to have Lin Wan as his concubine, so he abandoned me on the grounds that he had nothing to do. But he forgot that his current status was all due to me, the daughter of a merchant whom he disdained the most, by spending money on him.
