Xia Muqing is originally an archaeologist when she unexpectedly transmigrates. In another life, she becomes the useless daughter of a reputable family who is mocked and bullied by everyone. A brand new Xia Muqing is reborn from the ashes. From then on, she uses her skills and medical knowledge to subdue beasts and to seek revenge!

She uses poison to repay her sister who was born of her father’s mistress. She swears to make those who harmed and betrayed her pay with their blood!

As tragedy befalls Xin Siyue, she soon finds herself transmigrated into a novel world as a character. To her disappointment, she became the villainess who obsessively chased after the male protagonist while scheming to tear apart his relationship with his beloved.

To avoid her death route, Xin Siyue carefully avoided the male and female protagonists at every turn. Instead, she went off on her own to enjoy life. But somewhere along the way, she made a mistake– the male protagonist took notice of her!

Xin Siyue’s eyes teared up as she was being kissed in Chen Sinan’s arms. ‘No! This wasn’t in the plot!’
