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

The crisp sound of high heels echoed outside the door of the president's office at Zheng Hong Group, followed by a graceful figure walking in.

Lu Wei'an was reviewing documents with his head down when he looked up, and his eyes behind his gold-rimmed glasses held a hint of a smile.

"Miss Cheng?"

Cheng Wanwan walked up to his desk and greeted him with a smile, "Why are you calling me Brother Wei'an so formally? Just call me Wanwan."

Lu Wei'an closed the file and stood up, his smile polite. "What brings Wanwan to Zheng Hong? Shouldn't she be at Ou Teng?"

"Brother Wei, please stop making fun of me."

Cheng Wanwan sat down on the sofa and chuckled, "You're Lu Xiyan's older brother, how could you not know what he's been doing?"

Lu Wei'an straightened his suit and sat down, pressed the intercom to instruct his secretary to bring up coffee, and then smiled and said, "Xi Yan has never been bound by the Lu family rules since he was a child. He can do whatever he wants, and no one can force him to do what he doesn't want to do."

He chuckled softly, "The kind of freedom he enjoys is something most people can only envy."

"Yes, no one in the Lu family can do anything about him. It's just that his father died and Grandpa Lu dotes on him, so he just lets him have his way."

Cheng Wanwan's words were rather impolite, and Lu Wei'an couldn't help but look up at her.

"Judging from what Wanwan said, she has quite a bit of a problem with Xiyan." He asked with a smile, "Did she come to complain to me, her older brother?"

"What's there to complain about? I've sacrificed so much for him, but he doesn't care. Our Cheng family is even willing to be his stepping stone, but he still doesn't care. Since that's the case, I have no reason to force anything." Cheng Wanwan looked at Lu Weian and smiled slowly. "I came here today not for Lu Xiyan, but specifically to see you, Brother Weian."

"Me?" The man raised an eyebrow.

"I've come to congratulate you." Cheng Wanwan smiled. "Zhenghong Group has been on a roll lately, and has made several major breakthroughs in the medical field. The deadline for Zhenghong's betting agreement with Ou Teng is approaching, right? If this trend continues, Grandpa Lu's successor will definitely be Brother Wei An."

Lu Weian pondered for two seconds, then smiled gently, "Wanwan, it's too early to congratulate you now. The business world is unpredictable, and anything can happen at any moment. Right now, Zheng Hong is ahead of Ou Teng, but who knows if Ou Teng will catch us off guard in the next second?"

He raised his hand to adjust the frame of his glasses. "It's not safe to draw a conclusion until the very last second."

Cheng Wanwan's smile remained unchanged. "Brother Wei'an, although I don't understand the intricacies of business, I know that if one side has a sure victory, isn't the situation already decided?"

"Victory guarantee?" Lu Wei'an asked, puzzled. "What is this guarantee of victory?"

"Cheng's Group"

Lu Wei'an seemed somewhat surprised. "The Cheng Group?"

"Brother Wei An probably doesn't know this yet, but Lu Xiyan was willing to get engaged to me simply because I have the Cheng Group behind me. The Cheng Group can bring him the benefits he wants." Cheng Wanwan smiled lightly, "Of course, he also wants to defeat the Zheng Hong Group."

Cheng's Group is the largest pharmaceutical group in China. For Zheng Hong or Ou Teng to take over the entire medical sector, cooperating with Cheng's Group is the quickest and most effective way.

Lu Wei'an, of course, knew this. He feigned ignorance and asked, "Wanwan, what do you mean?"

"Wei An is a smart man, he must understand what I mean," Cheng Wanwan said with a smile. "As long as Wei An marries me, the Cheng Group will definitely support you."

Just then, the secretary at the door brought in coffee.

The woman, dressed in a smart business suit, with long, slightly wavy hair and delicate features, had just reached the door with her coffee when Cheng Wanwan scolded her, "Who gave you permission to come in at this hour?"

If outsiders heard this and spread it, Cheng Shao would definitely curse her to death.

"I'm sorry, Ms. Cheng, I'm sorry, Mr. Lu." The secretary apologized repeatedly, but was interrupted just as she was about to explain.

"This is my secretary," Lu Wei'an smiled gently. "She's been by my side for many years and knows the rules, so Wanwan doesn't need to mind."

After saying that, he glanced at the woman and said, "Put down the coffee and leave."

The woman nodded slightly, placed two steaming cups of coffee on the ebony coffee table, and as she left, she glanced quickly at Lu Wei'an before looking down again.

Only after the office door closed again did Cheng Wanwan continue, "Brother Wei An, what do you think of my suggestion?"

Lu Wei'an picked up his coffee and saw a glint of wolfish ambition in Cheng Wanwan's innocent eyes. "You want to marry me?"

"I don't want to marry you, I just want to join forces with you," Cheng Wanwan said with a smile. "Wei An hasn't gotten married yet, he's devoted to his work, isn't it because he wants Grandpa Lu and Uncle Lu to take a second look at you?"

"You're both Grandpa Lu's grandsons, but Grandpa Lu always favors Lu Xiyan. You're clearly the eldest young master of the Lu family, but there are always rumors that the real young master is Lu Xiyan, and that he's the successor designated by the old man. So, what about all the efforts you've made over the years, Brother Wei'an?"

Cheng Wanwan stirred the coffee in her cup and continued, "I still remember when you and Lu Xiyan made mistakes when you were little, you were always the one who got scolded and beaten, while he only got a few words of reprimand from Grandpa Lu. While you were locked up by Uncle Lu to reflect on your mistakes, he was out there continuing to live his carefree life as a young master."

"As you said, even if Zheng Hong is currently ahead of Ou Teng, the position of successor may not necessarily be yours. In the end, it may all be for nothing. It's better to take a gamble on a sure win."

Lu Wei'an sipped his coffee, his eyes darkening slightly as he pondered.

Seeing that he seemed to be wavering, Cheng Wanwan asked him, "Brother Wei'an, you've been using him as a stepping stone all this time, are you willing to accept that?"

"Only by truly gaining real power from Grandpa Lu will you have a chance to turn things around. And I guarantee that if we get married, the Cheng Group will be yours, and the Lu Group will be yours too."

Lu Wei'an put down his coffee, leaned back on the sofa, and smiled. "Sounds like a good deal. So, what do you want, Wanwan, for all that I'll get?"

Cheng Wanwan gave a cold laugh, "I'll make sure Lu Xiyan has nothing left in the Lu family, and no place to stand anymore!"

She raised the corners of her lips. As long as she married Lu Wei'an, she would be the young mistress of the Lu family! She might even become the chairman's wife of the entire Lu Group!

Before that, she wanted to ensure that Lu Xiyan and An Ning would get nothing and never find happiness!

As for her background...

If Cao Han could keep quiet forever, she wouldn't have to worry about anyone revealing this.

The fact that Anning is Cao Han's daughter will never change.
