********** in the Fetus

Lin Wanxing, a top quantum physics researcher, accidentally traveled through time due to an out-of-control particle collider, and became the female fetus in the belly of Su Qingwan, an inner disciple of the Qingyun Sect in the world of immortality. He also unexpectedly had a sibling brother. Being bound to the "Daily Sign-in System of the Cultivation World", she received rewards such as the innate Taoist body (incomplete) and marrow-cleansing liquid on the first day of her pregnancy. System benefits can also benefit her younger brother, and she can activate the "Twin Linked Absorption" mode to share spiritual nourishment in the mother's body. She first explored the path of cultivating immortality in her womb using the basic breath-taking method, and her younger brother passively received spiritual energy blessings due to her presence. The resonance caused by the twin fetal energy unexpectedly alerted the white-haired old man in the Qingyun Sect's Sutra Collection Pavilion. With the gentle protection of his mother Su Qingwan on the one hand, and the incredible opportunities brought by the system on the other, Lin Wanxing and his younger brother accumulated foundations in the womb, waiting for the day of their birth, and as twins, they embarked on this journey of cultivating immortality where crises and opportunities coexist.
