Ou Zihan nodded.

"Okay, it's getting late, go to bed early." Her Majesty the Queen looked at Ou Zihan kindly.

"Uh... Mom, I miss my dad, can you let me go out?" Ou Zihan asked cautiously.

"Do I have to go out? Your dad just returned to eastern Sichuan yesterday... If you want to go back, I can only give you three or four days."

"That's enough, that's enough, I just need to meet with my dad." Ou Zihan said excitedly.

"Okay then, I'll ask someone to arrange it later."

Ou Zihan returned to the bedroom with satisfaction. She originally wanted to tell Chu Tiance, but after thinking about it, she decided to forget it and wait until this matter was settled.

The next day, Ou Zihan secretly went to the royal wine cellar. As a princess, it was too easy for her to ask the bartender for a bottle of Qingshan Zhiding. It happened that the wine was still there, but it had been stored for many years. The bartender said that it might be stronger than before.

Her Majesty the Queen sent a transfer plane to escort Ou Zihan back to East Sichuan. There were no arrangements for the past few days. Knowing that she was not very adapted to life in the palace, she had to let her go back for a few days.

Royal Hospital

Chu Tianyi had just come out of the operating room, changed out of the surgical gown, and was sweating profusely. As soon as he walked into his office, he saw Chu Tiance sitting in his office.

"Hey, what gust of wind blew you here?" Chu Tianyi washed his hands and poured a glass of water for Chu Tiance.

"I came to ask you a question. Can cousins ​​be identified through DNA?" Chu Tiance frowned, seeming very anxious.

"What's wrong? Do you suspect that you and your eldest sister-in-law are not cousins?" Chu Tianyi asked.

"Yes, grandpa told me half of the sentence before he died. He said that if Ou Chuanshan opposed Xiaohan and I being together, he asked me to tell him that my mother is not... He said this."

"So, you suspect that the second half of grandpa's sentence means that your mother is not your biological child?"

"That's right! Tell me quickly, is it possible or not?" Chu Tiance was very anxious.

Chu Tianyi sighed and shook his head, "There's no hope for this. There's no way to verify a relationship like yours. Even if we take a DNA comparison, the significance of the identification is very low and it's not convincing at all."

"But if we really have a blood relationship, it would definitely show in the DNA sequence, right? At least the proportion would be much higher than that of people who have no blood relationship at all?" Chu Tiance didn't quite believe what Chu Tianyi said.

"It's just that your situation cannot be verified. Now, siblings can be verified, but cousins ​​really can't. At most, we can verify whether you are from the same family. However, this requires a lot of blood collection. It's better to collect the blood of the entire European family and compare them one by one. This takes a lot of time."

Chu Tianyi paused, "Even if it is verified, someone comes out and says it's a coincidence, we can't argue, because such coincidences do exist."

Chu Tiance was completely disappointed. What should he do? If they can't prove that they are not cousins, they can't be together.

"Unless your mother is still alive, there is really no way to verify it." Chu Tianyi said disappointedly.

"It's a pity that she is gone."

Chu Tianyi slapped his thigh suddenly, and he suddenly thought of something, "Oh, I remembered, brother, there is hope!"

"What hope? Have you thought of a good way?" Chu Tiance asked excitedly.

"Although I am not 100% sure, I think there should be no problem. Your mother still has something left in this world. As long as we get that, we can conduct an appraisal."

"What thing?"
