My Best Friend and Her Husband Transmigrated, and I Somehow Became Their Sister-in-Law

Liu Yunxi went tomb-sweeping for the husband who had died just after they registered their marriage, bringing along her best friend and the friend's husband. Somehow, she transmigrated. A strange System voice also appeared in her mind, granting her the power to heal the sick and save lives. It told her to complete a hidden mission in this strange world if she wanted to return home.

Later, she noticed that in this ancient household, her once fiery and lazy second sister-in-law suddenly wanted a divorce and even came to ask for her help. Her behavior was strange, and somehow, being around her felt more and more familiar.

Then she discovered that her husband's wastrel second brother had suddenly quit gambling and was coming up with all sorts of ways to make money for the family. But why did each money-making method seem more modern than the last?

What Liu Yunxi found even harder to understand was that she had been reborn in place of the original owner, and she remembered that in the original owner's previous life, her husband had gone to war and never returned.

So who was the man standing right in front of her, claiming to be her husband?
