Transmigrating as the Younger Sister of a Bigshot with Multiple Identities

Gu Yang didn’t hesitate. “Hair. The paternity test was done secretly by the Tong siblings. Since Tong Jiayin was in the same dormitory as me, she must have picked up the hair from the trash can.”

Gu Jin guessed that it was indeed hair.

Hair is the easiest sample to collect, but it’s also the easiest to mix up. Noticing Gu Yang’s last sentence, Gu Jin asked, “Did she ever pull out your hair?”

Gu Yang shook her head. “I wasn’t familiar with her, so she didn’t have the chance to pull my hair.”

Seeing the concern on Gu Jin’s face, Gu Yang asked, “What’s wrong? Do I need to pull out my own hair for a paternity test?”

Gu Jin nodded. “For accuracy, paternity tests usually require hair with a follicle, so plucked hair is preferred. However, hair that naturally falls out can also be used if it has a follicle and hasn’t been shed too long.”

Gu Yang understood but was puzzled. “In my memory, no one has pulled out my hair.”

Although she was popular at Hua University, she was close to her friends and didn’t recall any such incidents.

These friends wouldn’t help the Tong siblings behind her back. And if strangers had pulled out her hair, she would definitely remember them.

“Sister, are you suspecting that the hair used in the paternity test might be mixed up?” Gu Yang asked.

Gu Jin nodded. “It’s possible. If the hair wasn’t plucked directly from your head and was picked up from somewhere else, it could easily be mixed up.”

At that moment, Gu Yang remembered something.

Previously, at the Grass-Raising Internet Cafe, while she was playing games with Yan Xi, Yan Xi had been pulled by someone who seemed to be a hater.

If that person wasn’t Yan Xi’s anti-fan but was instead sent by the Tong siblings to pull out hair for a paternity test…

Yan Xi had been wearing a mask at that time, but she wasn’t. From a certain angle, Yan Xi looked quite similar to her. If the person had mistaken Yan Xi for her due to the mask, they might have taken hair from Yan Xi instead.

Given this, it’s not impossible for the hair sample to have been mixed up.

Gu Yang shared her suspicions.

Gu Jin and Feng Jue exchanged serious glances, their concern palpable.

Gu Pei, noticing the gravity of the situation, became serious as well.

Feng Jue quickly contacted Cao Cuo to request the surveillance footage from the Grass-Raising Internet Cafe.

“If we can identify the person who pulled Yan Xi’s hair and check for any financial transactions between them and the Tong siblings, we might confirm if they were involved,” Feng Jue explained.

Gu Jin added, “But I’m not sure how frequently the surveillance footage is overwritten at the Grass-Raising Internet Cafe.”

Cao Cuo’s response came swiftly: “The footage is overwritten every half month. Given the time that has passed, multiple cycles of data overwriting have occurred. It’s likely that the original footage is no longer accessible.”

Gu Pei, leaning in, asked, “Aren’t you a hacker? Can’t you retrieve it?”

Feng Jue shot him a sidelong glance. “Even hackers have limitations. With the footage overwritten so many times, the original data has been completely erased. There’s nothing left to recover.”

Gu Yang interjected, “If we can’t retrieve the footage, our only option is to conduct another paternity test.”

Gu Jin agreed. “That is indeed the most straightforward method.”

Gu Yang resolved, “I’ll contact Tong Rao right away. Given her concern for family ties with Tong Sinian and Tong Jiayin, she should be willing to cooperate.”

Gu Jin suggested, “Use a blood test. It’s more accurate.”

Since Gu Yang had recovered from her hemophilia, drawing blood would not pose any risk.
