The Favored Heiress

Li Qiao did not conceal her suspicions and, after a moment of silence, she shared her conjecture, "Our tests have found that a certain chemical element can cause chromosomal mutations, very similar to what your sister is experiencing.

Think carefully if, when you lived in the countryside, you had ever come into contact with pesticides or herbicides.

If you’re certain you have, please tell us the details, as that would significantly clarify the direction of our research."

Though the mutation was suspected to be caused by the element arsenic, with many chemical elements to consider, it was not yet possible to definitively attribute it to a single element or a reaction caused by a mixture of substances.

At this, Guan Mingyu and Guan Mingchen exchanged puzzled looks, both their faces a picture of confusion.

Guan Mingyu spoke up solemnly before Guan Mingchen could get a word in, "I haven’t touched any of these things. I studied chemistry and I know that pesticides are chemical agents.

Moreover... we are not from Zhao Family Village; we haven’t been allotted any land or homesteads there. My brother and I have been living in a farmhouse at the edge of the village all these years, and we don’t have such substances at home."

Guan Mingyu recounted their past with clear thought and a pale face.

Seeing her tense expression, Lian Zhen gestured for her to take a sip of water and asked gently in return, "Have you done any chemical experiments at school?"

Guan Mingyu, holding her cup, gave a wry smile, "I’m currently in my third year of high school. We don’t have many chemistry experiments, and even when we do, they’re carried out under the teacher’s guidance. I’ve never done an experiment myself."

She was isolated at school and had no friends, so even during class experiments, no one wanted to be her partner; at most, she was just a bystander.
