Don't Worry, Stepmom's Got This

Modern college student Grace traveled back in time to ancient times, taking on the role of a wicked stepmother. With the martial arts she had learned at a modern sports academy and a stash of high-tech gadgets, she outwitted her greedy relatives, made a fortune by opening a supermarket, organized drought-relief efforts, repeatedly foiled the villains' schemes, and protected her three stepchildren. She met and grew close to her brother-in-law, who had just returned from military service but was secretly an imperial envoy, and together they drove off foreign invaders. Once every enemy was dealt with, Grace was awarded a noble title, the emperor sanctioned her marriage, and the family reunited in peace.
