"Your mother originally stored the cord blood in a foreign hospital, probably just in case." Chu Tianyi said in surprise.

"But isn't the shelf life of cord blood only twenty years?" Chu Tiance frowned.

"It doesn't matter, as long as the cord blood still exists, it can be used. We just need to identify the cord blood and compare it with the DNA of Ou Chuanshan or Ou Yuhua. As long as it can be proved that they are not biological children, then you and your sister-in-law are naturally not cousins!" Chu Tianyi said excitedly.

"Great, do you know which hospital it is stored in? I'll send someone to get it right away."

"I still need to investigate, I don't remember the name of the hospital clearly at that time." Chu Tianyi said.

"Then hurry up, I'll go back first, tell me as soon as you have any news." Chu Tiance stood up and walked out. When he reached the door, he suddenly stopped and turned around. "Tianyi, how do you know that my mother has stored cord blood?"

"I accidentally saw it when I was checking her hospital records before." Chu Tianyi replied.

"Why are you checking her records for nothing?" Chu Tiance asked with a frown.

"I..." Chu Tianyi thought that he would have to tell Chu Tiance about this sooner or later. The reason why Ou Zihan didn't say it for so long might be that Ou Zihan took their husband-and-wife relationship into consideration. Instead of that, it would be better for him to say it.

Therefore, Chu Tianyi told Chu Tiance everything about Ou Zihan's suspicions and the results of his investigation.

Hearing this, Chu Tiance was completely stunned.

Chu Tianyi patted Chu Tiance on the shoulder, "My sister-in-law didn't let me tell you, worried that you couldn't accept it. Don't blame her. She had her reasons for asking me to investigate."

Chu Tiance said nothing, stood up and left.

Ou's House in Eastern Sichuan

Ou Zihan's return was warmly welcomed by the people of Eastern Sichuan. Who would have thought that Eastern Sichuan would have a princess? Everyone's support for her is obvious to all.

In the evening, only the father and daughter were left. Ou Zihan quietly took out the bottle of Qingshan Zhiding.

"Dad... you see, I am still filial. I know you like this kind of wine, so I specially asked the bartender in the palace for it and sent it to you!" Ou Zihan said obediently.

Ou Chuanshan saw the bottle of wine and smiled, "You have a conscience, girl."

"Of course I do. I didn't attend your birthday party some time ago, and I made you angry. I feel bad."

"Humph, if you want me to calm down, a bottle of wine won't solve the problem. You should break up with Chu Tiance as soon as possible and never have any contact with him again." Ou Chuanshan felt upset when he thought of this. "

Hey, Dad, let's not talk about this today, okay? Let your daughter have a drink with you?" Ou Zihan asked tentatively.

"You can't drink this wine. Go get a bottle of red wine. Drink with me. Then go to the kitchen to see if there's anything to eat."

"Okay!" Ou Zihan went to the wine cabinet and got a bottle of red wine. Then she went to the kitchen and brought out a few side dishes. Then the father and daughter started drinking.

Ou Zihan kept pouring wine for Ou Chuanshan.

"Dad, tell me your love story with my mom. Drink and talk." Ou Zihan said as she poured.

Anyway, he was free, so Ou Chuanshan started talking

. The wine on the top of Qingshan Mountain was really strong, especially when it was old. When Ou Chuanshan's bottle was almost empty, he started talking non-stop.

But he was a good drinker after all, so Ou Zihan didn't dare to ask about the past easily, for fear that Ou Chuanshan would see through her trick.

After waiting for a while, Ou Chuanshan finally fell into a daze and almost fell on the table.

Ou Zihan patted Ou Chuanshan on the shoulder, "Dad, keep talking, don't spoil the fun."
