If things were as Zhan Yangyi had said, then whether or not he had consummated his marriage with Chen Yutong remained an unknown.
However, Zhan Mohan did not voice this question in front of Zhan Yangyi, as it would only cause problems between Zhan Yangyi and Chen Yutong before everything was clarified.
"Big brother, you've had too much to drink. Go back and rest first. I will give you an explanation for this matter later," Zhan Mohan said earnestly.
Zhan Yangyi stared at him blankly for a moment before nodding, "Mohan, I actually feel you've become a bit different from before. I used to think you were like that man who abandoned me and my mother, but now it seems you are more humane than him."
Zhan Mohan did not react much to such praise, only helping Zhan Yangyi back to his room.
This drunken episode seemed to be just an occasional outburst from Zhan Yangyi. The next day, he and Chen Yutong were back to their usual selves, as if nothing had happened the night before.
But Zhan Mohan could not pretend to know nothing.
Whether it was for Wei Yumeng or for the Zhan family, he had to get to the bottom of this matter.
As the head of the Zhan family, how could he tolerate such a thing happening within the family?
When Zhan Mohan arrived at the company, he did not directly ask Fang Xun about work. Instead, he asked him to investigate Chen Yutong.
"Investigate for me where Chen Yutong lived before she married Zhan Yangyi, and what was the situation with their first night together."
Fang Xun was taken aback. Wasn't this investigating someone's private affairs? Moreover, who could possibly know about the situation of their first night behind closed doors?
"Mr. Zhan, this might be difficult..."
However, Zhan Mohan gave him a cold look, and Fang Xun naturally had no reason to refuse. He could only prepare to carry out the task.
Zhan Mohan always believed that if certain actions were taken, there would be no trace left behind.
Fang Xun initially thought this would be one of the most challenging investigations he had ever undertaken. Fortunately, Chen Yutong's social circle was not overly complicated.
According to Fang Xun's investigation, before marrying Zhan Yangyi, Chen Yutong had mostly stayed in hotels for the convenience of her work, usually for the entire duration of a project.
During that period, Chen Yutong was collaborating with the Zhan Group, so Fang Xun easily found out the location of the hotel where she was staying.
"Hello, I'd like to ask about someone. Did Chen Yutong used to live here?" Fang Xun stopped a passing waiter, deciding to try his luck.
Upon hearing Chen Yutong's name, the waiter's eyes lit up. "Are you asking about her because you're from the media?"
Fang Xun was about to explain, but the waiter continued on his own, "Many reporters have asked me about this before. Chen Yutong did indeed stay here. In fact, after she spent a night with Mr. Zhan, news of their engagement spread."
"You remember quite clearly," Fang Xun felt his luck was pretty good, having found someone who seemed to know something.
"Of course. Although many people come and go in our hotel, there aren't many prominent figures like Miss Chen, so she's certainly memorable."
Fang Xun continued to ask, "Did anything unusual happen that night?"
"Unusual things?" The waiter fell into thought. "Now that you mention it, there was indeed..."
The waiter spoke with a mysterious air and extended his hand to Fang Xun. "I assume you know the rules, being a reporter. What I'm about to tell you is exclusive. I haven't told anyone this before."
Fang Xun understood and immediately handed the waiter some cash.
Indeed, upon seeing the money and counting it, the waiter's eyes crinkled into a wider smile. "Come closer, don't let anyone else hear."
Fang Xun leaned in, and the waiter whispered in his ear, "That night, Miss Chen ordered a bottle of red wine and a packet of sleeping pills from here."
"Sleeping pills?" Fang Xun was taken aback. Although the medicine sounded suspicious, if Chen Yutong had taken it for her own sleep, he couldn't suspect anything.
"Yes, I initially thought she was using it herself, but later I felt something was amiss. Think about it, how could it be such a coincidence? She asked for sleeping pills, and the next day their engagement was announced."
This reminded Fang Xun that while each event taken individually might seem normal, when viewed together, it was hard not to feel something was off.
However, even so, he hadn't obtained any direct evidence.
But the waiter seemed to know no more, so Fang Xun dismissed him and planned to ask others.
Just then, two passing waiters were chatting.
"Did you really keep that cup?"
"Yes! Miss Chen Yutong is my goddess. I finally had a chance to get something related to her."
Fang Xun walked over. "Are you talking about a cup that Chen Yutong used?"
The waiter became wary upon seeing Fang Xun, but then his resolve wavered when he saw the money in Fang Xun's hand.
"Sell me that cup. I'll pay a high price."
After obtaining the cup, Fang Xun immediately sent it to the relevant authorities for testing. According to the waiter's words, the cup had been used around the time Zhan Yangyi had visited.
However, it couldn't be guaranteed whether it was used by Zhan Yangyi or Chen Yutong. It was a matter of luck.
A day later, the test results finally came in.
Traces of red wine were indeed found in the cup, and within those traces, the components of sleeping pills were detected.
Upon seeing the analysis report, Zhan Mohan's brows furrowed even deeper. This report undoubtedly confirmed his suspicions.
Chen Yutong had given Zhan Yangyi sleeping pills to make him believe they had consummated their marriage. In reality, Zhan Yangyi had merely fallen asleep after taking the pills, and she only needed to prepare a little the next day to make him believe they had been intimate.
This made Chen Yutong's reasons for approaching Zhan Yangyi and accepting his proposal very intriguing.
This also raised another question: if they had not consummated their marriage, then what about Chen Yutong's child?
During their previous observations, neither Wei Yumeng nor Jing Yan had found any issues with Chen Yutong. Therefore, to uncover the truth, a different investigative approach was needed.
Zhan Mohan pondered for a moment, then asked Fang Xun, "I remember you previously investigated the doctor who examined Chen Yutong. Go and find him for me. I want to ask him myself."
"Mr. Zhan still suspects that doctor?"
Zhan Mohan nodded. While the previous investigation seemed to have yielded results, it was clearly based on others' opinions of the doctor, and it couldn't prove that he truly had no connection with Chen Yutong.
