To investigate Wen Xueshan's suspicion, they naturally needed to find out where Wen Xueshan went after telling Wei Yumeng that she had something to retrieve that day.
So, the first people Wei Yumeng thought of were the workers present that day. Although they couldn't be sure if they had seen anything, it was still a lead.
Despite some unpleasantness with the workers due to the incident, some were still willing to cooperate with Wei Yumeng.
"Miss Wen? I saw her go back to the office that day, and she came out and left not long after, but I don't know which direction she went."
Although some workers had seen Wen Xueshan, they clearly hadn't paid close attention to her whereabouts.
Zhan Yichen had to turn to Wei Yumeng and ask, "Sister-in-law, is there any surveillance on this construction site?"
"Yes, but..." Wei Yumeng sighed, "There's no surveillance installed near the kitchen, so I'm afraid there won't be any clues."
Mu Linjing couldn't think of any other way. She had initially thought that as long as the suspect was identified, some clues would be found by following the investigation, but it seemed the matter was far from that simple.
"Miss Wei?"
At this moment, a voice came from behind them.
Wei Yumeng and the other two turned around and saw the cautious cook.
"Miss Wei, you're still investigating this, aren't you?" the cook said with a sigh. "Actually, I saw Miss Wen that day. She came to the kitchen, but I'm not sure what she did."
These words immediately put the three of them on alert.
Wei Yumeng confirmed again, "You really saw her?"
"Absolutely. That day, according to the usual schedule, I hadn't started work yet. But that day, my husband and I had a fight, and I had nowhere to go, so I arrived early. When I came, I happened to see Miss Wen coming out of the kitchen, so I'm sure she must have gone in."
The cook said, still a little uneasy, "But I don't think Miss Wen would tamper with the food. This project has her involvement too."
Wei Yumeng nodded, "I'm not saying she did this, but just to be safe, I need to investigate everyone from that day thoroughly."
The cook nodded, but then she said gratefully, "Miss Wei, you are the best and most reasonable superior I have ever met. You didn't blame me for this matter. I'm truly touched, so if you need any help, please don't hesitate to ask."
"Alright, I understand." Wei Yumeng was finally relieved. At least not everyone treated her and Zhan Mohan as irresponsible people.
After that, the three of them asked some more questions about the food that day before leaving.
"What are we waiting for? Since we know Wen Xueshan went into the kitchen, it's highly likely she did it. Let's just call the police!" Mu Linjing suggested. She didn't want to see Wei Yumeng upset anymore, so the sooner this matter was resolved, the better.
Zhan Yichen gave her a helpless look, "Idiot, although we can confirm she went to the kitchen, we can't prove she was the one who tampered with it. She'll have enough reason to say we're framing her to clear our names."
Mu Linjing pouted, "Then what do you suggest we do? If we can never find proof, do we just keep searching like this?"
Wei Yumeng remained silent, deep in thought. The probability of Wen Xueshan being involved was now the highest among everyone.
Moreover, she hadn't had a chance to return to the scene after the incident. Perhaps they could use this to their advantage.
However, this plan seemed a bit risky, and no matter what, she didn't want Zhan Mohan to bear the consequences.
But at this moment, Mu Linjing's voice pulled Wei Yumeng out of her thoughts.
"Yumeng, look quickly!"
Wei Yumeng then looked at Mu Linjing's phone. The forum had exploded. Someone had posted the arrangements for this project online.
It clearly stated the division of labor among the staff at the time, and naturally, it also clarified that the project managers were Wen Xueshan and Wei Yumeng.
And under Wen Xueshan's name, it clearly stated that she was on leave that day.
Naturally, everyone turned their attention to Wei Yumeng.
"I thought it was strange. Mr. Zhan already runs such a large company, so how could such a small problem occur?"
"Right, right. Now it's clear that Mr. Zhan is taking the blame for his wife! Mr. Zhan is indeed a good man, but this Wei Yumeng doesn't know how to cherish him, causing trouble and making Mr. Zhan bear the consequences!"
"I always thought this Wei Yumeng wasn't suitable for Mr. Zhan. You all didn't believe me, but now you know, don't you?"
Mu Linjing was furious and shouted, "You all know squat! Just because Wen Xueshan was on leave that day, does that mean she has nothing to do with the project? She's also a project manager! Why are you only blaming Yumeng!"
As she spoke, she almost threw the phone, but Zhan Yichen stopped her.
However, the eruption of this matter was enough to turn the entire situation around.
But when Mu Linjing looked at Wei Yumeng, Wei Yumeng curved her lips, looking as if she wasn't worried at all.
"Yumeng, are you being silly? The situation is like this, and you can still smile?"
Wei Yumeng was glad that things were developing this way. As long as she could take Zhan Mohan's place, even if nothing was found, she would be the one held responsible.
"Linjing, Yichen, come here. I have something to tell you."
...
Sure enough, not long after, the police arrived directly. "Miss Wei, we have reason to suspect you are involved in this worker poisoning incident. Please come with us."
"Have you investigated properly? This was not Yumeng's doing at all!" Mu Linjing stepped forward and blocked Wei Yumeng.
However, Wei Yumeng pushed Mu Linjing aside. "I'll go with you."
"Yumeng..." Mu Linjing felt heartbroken, but she couldn't do anything.
Wei Yumeng, on the other hand, didn't feel anything was wrong. It was she who had planned to bear everything, so this outcome was within her expectations.
"Don't worry, I'll be fine. But don't forget what I told you. How things turn out depends on you two."
Zhan Yichen nodded, "Sister-in-law, don't worry, we'll arrange everything."
Wei Yumeng then left with the police with peace of mind.
Mu Linjing and Zhan Yichen looked at Wei Yumeng's retreating figure with sadness. However, this also reminded them that how things would turn out might depend on the two of them.
