บท 1197: Begin Your Performance（5）

The man in the white lab coat left before Xu Cheng came out of the restroom. When she saw Xu Cheng slowly walking towards her, Lina tightly grasped the hair sample in her hand. She unintentionally placed the hair samples in her purse.

Since Eric hadn't yet returned, Xu Cheng didn't dare say that much to Lina. She obediently sat beside Lina and quietly waited for Eric to return.

Lina didn't say anything. Although she looked calm on the surface, in reality, her heart was in a frenzy.

She looked at Xu Cheng's hair. It was black and long. It was also very coarse and stiff.

The man was right. Since they were both here, why didn't they choose to get a blood test but instead opted to use a hair sample?

Who was the one who first brought up using a hair sample?

Eric!

Lina's eyes tightened, and her thoughts went on overdrive.

If Xu Cheng had used someone else's hair to do the DNA test, then where did she get the hair sample?
