After returning home with the child, her ex-husband knelt down and gently coaxed her.

"What's wrong?" Liang Xu asked.

Lu Xiyan put down his teacup and looked at Liang Xu. "She also has Rh-negative blood, so she should know how dangerous it is to have a child with this blood type. If she didn't want the child, she should have terminated the pregnancy instead of risking her life to give birth. Especially since she was premature, the risks are even greater."

Liang Xu pondered for two seconds, then asked, "What if she wanted the baby when she was pregnant, but didn't want it after it was born and she found out it was a girl? After all, in those days, many people in the countryside still had that kind of preference for sons over daughters, right?"

"If she simply didn't like girls, she could have easily given the child away or abandoned her in her hometown. Having lived in the Cheng family for so many years, she wouldn't be unable to raise a child, much less abandon her just because it's a daughter. Besides,"

Lu Xiyan narrowed his eyes slightly. "Look at her, she's been in the Cheng family for decades, taking meticulous care of Cheng Wanwan. She even raised Cheng Wanwan when she was little. Does she seem like someone who doesn't like her daughter?"

Liang Xu frowned. "Does she have some kind of mental problem? Does she not like her own daughter and only like other people's daughters?"

"Does he like someone else's daughter?"

Lu Xiyan pondered these words, his fingertips twitched suddenly, and his eyes changed abruptly. "That's right, why doesn't she like her own daughter and cruelly abandon her, preventing her from entering Jinghai when she grows up, yet she is so considerate to other people's daughters?"

Lu Xiyan gave a cold laugh, then suddenly realized something. "A woman who has just given birth is not resting properly, but instead has to travel a long distance with her newborn child to Yunnan, which is so far away."

"Going back to her hometown was just a cover; Dianchi Lake is where she really wants to go." Lu Xiyan's eyes sharpened. "Because it's far enough from north to south."

Liang Xu was still pondering the meaning behind his words when he heard him sneer.

"It's not that she doesn't like her daughter," Lu Xiyan said in a low voice, meeting Liang Xu's questioning gaze. "It's that what she abandoned might not have been her daughter at all!"

Liang Xu was startled and almost knocked over the teacup in his hand.

"You mean, the one she abandoned in Dianhai was someone else's daughter, while her own daughter is right beside her!" Liang Xu's eyes widened, goosebumps instantly rising on his skin. "It's even highly likely that it is—"

Lu Xiyan suddenly gripped his teacup tightly. "Cheng Wanwan!"

What a clever trick of switching the prince with a cat!

A nanny, how could she have such amazing skills!

They dared to switch the newborn baby girl right under the noses of the Cheng family!

Liang Xu was so shocked he couldn't utter a word. "This...this...does this mean An Ning is very likely Cheng Shao and Han Yun's biological daughter?"

As soon as he finished speaking, a murderous intent flashed in Lu Xiyan's eyes.

If that's the case, he should skin Cao Han alive!

All of Anning's suffering stemmed from her!

If it weren't for her, Anning would have grown up carefree in the Cheng family!

The person he should have been engaged to was An Ning!

"However, this is just our deduction, not the final result." Liang Xu thought for a moment, "How about I just get a paternity test done on Cao Han and Cheng Wanwan?"

"Extracting DNA from them is too troublesome." Lu Xiyan thought for a moment, then looked at Liang Xu, "Haven't we caught that rotten apple in the forensic department yet? Why don't we use this to lure him out?"

Liang Xu asked, "What do you mean?"

"Just do a paternity test on An Ning and Cheng Shao, and do it in a high-profile way." Lu Xiyan stared at the clear tea in his cup. "A dog will bark at its owner if it hears a strange noise."

......

Late at night, the full moon hangs high in the sky.

By this time, everyone in the Cheng family had already gone to sleep, and the servants and stewards were also resting.

A soft knocking sounded on the door of a room on the second floor of the servants' quarters.

Cao Han was folding clothes when she heard a knock on the door. She asked warily, "Who is it?"

Who would come looking for her at this time?

"It's me," Cheng Wanwan's voice rang out from the doorway.

Cao Han was slightly surprised and quickly got up to open the door.

"Miss? Why aren't you asleep yet? Are you hungry and want something to eat?"

She asked with concern, but Cheng Wanwan didn't answer and went inside, closing the door tightly.

Cao Han looked at her, puzzled.

Cheng Wanwan entered the house and looked around. The servants' quarters were a place where the Cheng family provided housing for their servants. Each room was a standard one-bedroom apartment, fully furnished.

Cao Han had lived in the Cheng family for decades, so she received special treatment. Her room was a two-bedroom apartment, and she lived on an entire floor by herself.

She almost never goes back to her hometown, and spends every year during the Spring Festival and holidays with the Cheng family, so her room has quite a few things.

"Aunt Cao," Cheng Wanwan said, walking into the house with her back to Cao Han, "you haven't gone back to your hometown in all these years. Don't you miss your daughter?"

Cao Han didn't know why she suddenly came over to ask these questions. Her gaze fell on her graceful back. "What's there to think about that ingrate? When Cao's mother looks at you, it's like seeing her own daughter, even closer than her own daughter."

Cheng Wanwan turned around, smiling sweetly, "Then Aunt Cao must be willing to do anything for me?"

"Of course," Cao Han said, slightly excited. "Aunt Cao is willing to do anything for you, Miss."

Cheng Wanwan looked at her with a cold gaze, but a smile played on her lips. "Aunt Cao, you heard it that day too. Anning said her mother died. You and I both know how her mother died."

She sat down and got straight to the point, "The police will find you soon, what will you do then?"

"I know!" Cao Han squatted down in front of her. "Miss, Anning's mother's matter has nothing to do with you. Even if the police arrest me, I won't say anything."

Can't say anything?

Cheng Wanwan didn't believe it; only the dead can't talk.

"Aunt Cao, if you treat me like your own daughter, you should know how much I've suffered recently."

As Cheng Wanwan spoke, two lines of tears rolled down her cheeks. "Today, a friend from the forensic science department told me that Anning is going to get a paternity test with my parents."

"What!" Cao Han exclaimed in shock. "You mean An Ning... she's going to get a paternity test?"

"Yes, she said I killed her mother, and now she's trying to steal my parents away!" Cheng Wanwan looked at Cao Han, whose face was deathly pale, through teary eyes. "Of course I know she's not my parents' biological daughter, but she definitely has the ability to make herself look real! Lu Xiyan will definitely help her too! What if my parents actually believe her then? Then I'll have nothing left!"

Cao Han's legs gave way and she collapsed to the ground. "She's going to get a paternity test... How could she possibly want to get a paternity test..."

"Aunt Cao! An Ning has gone too far!" Cheng Wanwan suddenly knelt down in front of her. "Aunt Cao, please help me again!"

Looking at her tear-streaked face, Cao Han asked, "Help? How can I help?"

"Aunt Cao, instead of waiting to be arrested by the police, why don't you deal with Anning for me before that happens?" Cheng Wanwan gently wiped away her tears. "That way, she won't be a threat to me anymore, and Lu Wei'an has already agreed to marry me. As long as Anning is quiet, I can live a stable life as the eldest daughter of the Cheng family and the young mistress of the Lu family."

"Aunt Cao, you treat me like your own daughter, and I treat you like my own mother. You must really want to see me living this kind of life, right?"

She looked at Cao Han's pale face, tears streaming down her face, and slowly smiled, "How about I call you 'Mom'?"

"Mom, please help your daughter."
