After the divorce, the crazy CEO knocked on his ex-wife's door every night.

Then, she casually suggested, "Oh, why don't you let me handle this? That would be good, and you two can take the opportunity to have a good chat."

After saying this, the elder took the child, who was still sobbing softly, from the young man's hands and turned to walk towards the stairs.

As she walked further and further away, she finally disappeared into the distance.

Only after the figure had completely disappeared from sight did Han Xin slowly turn around, gaze at Li Siyuan's face, and ask, "Why didn't you spend Shen Xuan's important day with her? Did you specially take time out of your busy schedule to come see us, mother and daughter?"

His words clearly carried a hint of confusion and doubt.

Upon hearing the question, he first loosened his tie slightly, as if trying to ease his inner tension.

Then he slowly turned around, walked to the sofa next to him, sat down, crossed his legs, and calmly replied, "Didn't you say this yourself? You hoped I could spend more time with you and our daughter. Now that I've finally returned home as I wished, are you unhappy?"

She bit her lower lip tightly, her eyes flashing with complex emotions as she stared at the man in front of her who had been so cold and indifferent to her and her child.

Her words came out coldly, one word at a time: "Don't you really realize at all? Weiwei doesn't like you, and I don't want you in our lives either. Since you've already planned to leave here and live somewhere else, I hope you won't come looking for us again. It would be best if Shen Xuan also had nothing to do with you anymore, so at least you'll understand that you're actually better off alone."

It seemed she had touched on a sensitive area he least wanted to touch, which instantly turned his previously calm expression extremely unpleasant.

His hands unconsciously gripped the edge of the sofa beside him so tightly that his knuckles almost turned white.

The image of Shen Xuan celebrating his birthday outside with another man involuntarily flashed into his mind, and an intense, suffocating pain surged into his heart.

This kind of behavior—directly exposing someone's hidden thoughts without any hesitation—is as embarrassing as revealing something extremely private to everyone.

Even an adult would find it difficult to remain calm in this situation.

"I'm here to celebrate my daughter's birthday this year, not to cause trouble."

Li Siyuan tried his best to suppress the anger surging within him, and said in a tone that was as calm as possible but slightly strained, "If you have any complaints about me, please wait until after this special day is over."

Han Xin's lips curled into a sarcastic smile. "Celebrating your so-called daughter's birthday with you? Hmph, I'm afraid you've been abandoned by that woman named Shen Xuan and have nowhere else to go, so you're just pretending to care about your father-daughter relationship."

Upon hearing her bluntly reveal the truth, Li Siyuan, who had been trying to control his emotions, immediately frowned.

"Please take back those false statements you just made!"

His cold and sharp eyes seemed to gather countless icy chills, showing no warmth even when he looked at his ex-wife with whom he had a previous marriage.

Faced with this attitude, Han Xin simply responded with a soft "hmm," without being intimidated or falling silent.

Because she knew very well what Li Siyuan was really like in his daily life, she didn't feel much fear when facing such a man.

“Everything I’ve said is based on facts, Li Siyuan. I will not learn to obey you like Shen Xuan, who only blindly follows you. From today onwards, you should move out of this house completely. We will never need to see you again, no matter when or where. Please remember that Weiwei has a father in her life, but that person will definitely not be you.”

Upon hearing this, the question of blood type resurfaced in his mind.

Li Siyuan suddenly stood up from the sofa, his footsteps approaching her with an undeniable sense of pressure. He asked sternly, "When Weiwei was hospitalized last time, the doctor clearly stated that she has type B blood. I remember your blood type is A, and mine is also type A. We are both type A, so how could we have a type B child? So, Xinxin, how did this child come about?"

Li Shulian, who was standing at the bottom of the stairs holding her child, turned deathly pale when she saw this scene.

"What are you talking about?"

Han Xin was stunned and stood there, unable to believe her ears.

Li Siyuan's face darkened, and he snorted coldly, "Your blood type is A, and so is mine. However, Weiwei is blood type B. Do you know what I'm questioning?"

His words were full of questioning and dissatisfaction, and his tone was low and forceful.

"Li Siyuan, do you doubt that Weiwei is not your biological daughter?"

Han Xin hurriedly stepped forward, grabbed his sleeve tightly, her eyes filled with fear as she looked into his questioning and angry eyes.

"Don't you know whether she's my child or not?"

He narrowed his eyes, staring at her coldly and mercilessly, his gaze sharp as a knife, a deep disgust flashing in his eyes.

He had originally intended to preserve some dignity for her, but she kept touching the most sensitive part of his heart.

"Impossible! This is absolutely impossible! How could Weiwei have type B blood? She must be your child, she is my biological daughter, really, I swear, you must believe me, Weiwei is definitely your flesh and blood."

Han Xin's voice trembled as she desperately tried to prove her innocence.

"Then explain to me how it's possible for two people with type A blood to have a child with type B blood?"

Li Siyuan's voice was cold and ruthless, without the slightest emotional fluctuation.

"This is completely impossible. The hospital must have made a mistake. Weiwei could not possibly have type B blood."

She spoke urgently, hoping that her determination would sway him.

Li Siyuan waved his hand impatiently, shaking it off. His tone was so cold it seemed to freeze someone, as he asked, "Besides what happened that night, you know what else you've done, don't you? Don't you know?"

Her brows furrowed immediately, and her fingers unconsciously gripped her sleeve. She was filled with doubt and unease, completely unaware of what could have caused Weiwei's blood type to be so abnormal.

"Si Yuan, I really don't understand why this is happening. Weiwei is our child, how could there be such a big difference?"

Her words were filled with helplessness and confusion.

"Not sure?"

His voice was filled with intense anger, as if every word was about to burst forth. "Then think back carefully to what you and Lian Tuo did during those months abroad. Weiwei was diagnosed with congenital thalassemia, a disease that can only be inherited from one parent. Tell me, is the problem with you or with me?"

His tone was full of accusation and distrust.
