- Description from Novelupdates

When she woke up, she had transmigrated into An Jiuyue, a woman living with two young children on a mountain after her husband abandoned her. She was pushed to the ground, and now, there was a bloody wound on her head.

With only a handful of rice left in the rice bag, she had relied on digging wild vegetables to satisfy their hunger every day. Her children were so often starved that they were all skin and bones. On top of that, a wicked woman threatened her to sell her son! If she refused, the woman would snatch him away forcefully.

But An Jiuyue took a deep breath, revealed her sharp claws, beat the woman up, and threw her out of the house. She could show the woman she was not to be messed with!

They were out of rice and vegetables now, but she was not afraid. Acquiring food using her spatial abilities was as easy as curling her fingers!

Moreover, her spatial abilities were unlimited, and her medical skills did not deteriorate. She could no doubt earn money and raise her children well!

As for her ex-husband…

The prince, who had returned from the battlefield, smiled maliciously. “My beloved concubine, please calm down. I brought back a mountain of gold from the battlefield as a gift for you and our children.”
