After Our Arranged Marriage, I Got Pregnant with My Mortal Enemy's Child

[Wealthy Families + Feel-Good + Devoted Couple + Pregnancy + Fantasy] One-line pitch: After an arranged marriage, she gets pregnant with her nemesis’s child. To repay her adoptive parents for raising her, Xie Lan agrees without hesitation to marry into the Jiang family. On her wedding night, her nemesis Qi Yan suddenly appears. After one reckless night, she finds herself pregnant with his child. Did her adoptive father send Xie Lan to the Jiang family to get through a business crisis, or is there another secret behind it? Pregnancy? Or a soul pearl entering her body? This makes no sense! Xie Lan: “I... think I might be pregnant.” Everyone: “No, a soul pearl has entered your body. You’re a perfect vessel for cultivation, born with the gift.” Xie Lan: “No, I really am pregnant.” Everyone else is earnestly cultivating and seeking the Dao. Only Xie Lan and Qi Yan are busy falling in love. They fight a few minor monsters along the way, fall in love, and then have a baby.
