Ou Zihan never had the habit of knocking on the door. She just pushed the door open and stuck her head in.

In this house, she was the only one who dared to enter the study at this time without knocking.

Ou Chuanshan raised his eyes and glanced at her, "You still can't change the habit of entering without knocking."

"Hehehe..." Ou Zihan walked in directly, took a chair and sat opposite Ou Chuanshan.

"Let's settle the accounts."

"Who are you talking to, little girl?" Ou Chuanshan turned a page of the book without raising his head.

"I just took a shower and I don't smell at all. I smell it. If you don't believe me, smell it? There's no one else in this room. Of course I was talking to you." Ou Zihan was obviously playing dumb.

Ou Chuanshan often let out a sigh. Knowing that she was playing dumb, he did not force her to call him. He closed the book and said, "Tell me, what are you calculating?"

"My support from birth to now." Seeing the calculator on the table, Ou Zihan took it.

"Let me tell you, I am not easy to raise. I had milk powder and diapers before I was one year old. I went to kindergarten from three to six years old. After six years old, I went to school. I bought clothes, had meals, snacks, and after fourteen years old, I had my period's sanitary napkins..."

Ou Zihan said as he pressed the calculator.

Ou Chuanshan sat opposite him and listened quietly.

"And I get sick every year. I'm not in good health, and I get sick every year. And the car I bought after graduating from college, a Maserati, is about two million yuan," Ou Zihan thought for a while, holding his chin, "and the mental loss I've suffered from the lack of fatherly love over the years, add it up..."

"No! Oppa said that he won't give you money after you turn 18, so I'll deduct the money for the car and the money for food and clothing for a few years, and round it up to 20 million!" Ou Zihan handed the calculator to Ou Chuanshan.

Ou Chuanshan looked at the numbers on the calculator, his face expressionless, he had lost too much money to this daughter, let alone 20 million, even if it was 200 million, he would give it to her.

It's just that what he wants to compensate her with is family affection, not money. This lady actually asks for money.

"Why? You think it's too much?" Seeing that Ou Chuanshan didn't say anything, Ou Zihan said, "I'll give you another 50% discount! Ten million! No less!"

"Bargaining with your biological father..."

"Now it's you, the biological father, and I, the biological lady, who are bargaining."

"Go to my bedroom and bring me my wallet. It's in the drawer of the bedside table." After Ou Chuanshan finished speaking, he opened his book again.

Get a wallet? This is possible!

Ou Zihan hurried to Ou Chuanshan's bedroom, took out the wallet from the bedside table and handed it to Ou Chuanshan.

Ou Chuanshan took out a black bank card from his wallet.

Ou Zihan's eyes widened. It was a black card. It was a black card!

"Take this." Ou Chuanshan handed the card to Ou Zihan.

"Black card, this is all your property, right? You gave it all to me? Oh my god, I'm a little flattered!" Ou Zihan took the black card in her hand and said excitedly.

Ou Chuanshan thought Ou Zihan didn't recognize this black card. Although Lan Chen was the richest man in Asia, some banks might invite him to apply for a black card, but he was sure that Lan Chen didn't have a black card of this bank, because this world's most famous bank would only invite people with status to apply for it, and one of the prerequisites was that they must be nobles.

"Do you recognize this card?"

"Yes, I had one before." Yes

, she did have one exactly like it before, except for the card number and name, everything else was the same, it was given to her by Chu Tiance.

"Who gave it to you?"

Ou Zihan's mind suddenly flashed that person's face, "I'm going back to my room first, thank you for the black card! I promise I won't waste money!"
