Shen You'an calmly and rationally analyzed one by one: "When they smile, the slight indentation in a specific position on one side of their cheeks, almost imperceptible, even the depth is consistent. This subtle mutation of muscle attachment points is also inheritable."
In her mind, Shen You'an recalled the contour information of Gu Bichen: "But Gu Bichen's ear is the common oval shape, his iris texture is uniform and unremarkable, and his facial muscle movement pattern when smiling is completely different. From dominant genetic traits, Gu Bichen's similarity to Professor Na is far lower than expected from a random passerby, which is extremely abnormal."
"Moreover, Rong Xianning and Professor Na both don't consume scallions, ginger, or garlic, a sensitivity caused by certain genes affecting taste receptors."
