Yes, Dad only has Wei Lili and her daughter in his heart; he doesn't even see his own daughter.

He probably no longer has a place for his mother in his heart.

"Dad, do you still remember Mom?" Wei Juan smiled bitterly, her voice dry as she spoke.

"Why are you bringing up a dead person on such a fine day?" Wei Zhentian glared at her, displeased. "Are you always trying to bring me bad luck?"

Wei Juan clenched her fists tightly, her face growing paler. "My mother is your ex-wife! She was also your right-hand woman on your entrepreneurial journey. If it weren't for my mother, where would you have such a large business and so much wealth? My mother sacrificed so much for you, worked herself to death for you, and in the end, is she just a dead person in your eyes?"

Wei Juan's voice trembled. She hadn't cried when Wei Zhentian neglected her and made her suffer, but when he treated her mother like this, tears welled up in her eyes and fell in large drops. Her voice was choked with sobs, "Can't you even give her the most basic respect?"

"What exactly are you trying to say?!" Wei Zhentian slammed his chopsticks down, his face cold and displeased as he looked at Wei Juan.

“I went to my mother’s grave today.” Wei Juan wiped away her tears, choked up, and looked stubbornly at Wei Zhentian. “I found a very strange flower growing next to her grave. I picked one and asked a doctor nearby. The doctor said it was a poisonous plant that could kill people.”

"So what? Did you wash your hands?" Wei Zhentian's attention fell on Wei Juan's hands. "You touched that filthy stuff outside, go wash your hands right now, don't bring the dirt into the house!"

In an instant, Wei Juan's heart sank to the bottom.

She had expected Wei Zhentian to be surprised or shocked upon hearing this, and perhaps even to offer some explanation, but he wasn't.

He was not surprised at all.

This is enough to show that he was aware of the existence of the heartbreak grass.

This further suggests that it is highly likely that Wei Zhentian was the murderer who killed his mother back then.

"You really aren't shocked at all?" Wei Juan said, laughing and crying as she walked towards Wei Zhentian. "Aren't you going to ask me why there are heartbreak plants in front of my mother's grave?"

Wei Zhentian realized something, and his eyes darted away.

These subtle changes were all noticed by Wei Juan, which further confirmed her suspicions.

“I remember you personally brewed the medicine for Mom, three times a day without fail. Back then, the neighbors all praised my mother for marrying a good husband, who stayed by her side even when she was seriously ill…” Wei Juan smiled bitterly, her eyes filled with increasing disappointment as she looked at Wei Zhentian. “You know about the poisonous plant, don’t you?”

Wei Zhentian's eyes became increasingly evasive, his face cold and stern. "I don't understand what you mean. You go back to your room right now."

"Are you pretending not to understand?" Wei Juan, who was usually timid, confronted Wei Zhentian at this moment. "You poisoned my mother, didn't you? Did you poison her to death back then?"

"Shut up!" The next second, Wei Zhentian stood up abruptly and slapped Wei Juan hard across the face.

A crisp slap rang out, and Wei Juan was slapped so hard that she fell to the ground. Her ears were ringing, and blood slowly trickled from the corner of her mouth. Wei Juan covered her swollen and burning face, raised her teary eyes, and stared at Wei Zhentian in disbelief.
