"A straw."
Li Ze immediately said, then turned his head to look at Shen Wendong, catching the change in his expression.
When he heard the word " straw," Shen Wendong's expression froze, but he quickly concealed it.
Li Ze smiled.
He guessed correctly and understood everything.
Milk tea was not poisonous.
The straw was poisonous.
Shen Wendong used the trick of stealing the sky and changing the sun to replace the original straw, causing Xu Hongwen, who did not know anything, to take poison and die.
Li Ze relaxed after thinking this through.
There was only one problem now, where did the non-toxic straws provided by the milk tea shop go?
The nine of them did not leave the villa.
Wu Kang and his men had searched the place thoroughly, but they did not find anything suspicious.
So, where did Shen Wendong put the straw?
Seeing how confident the other party was, he was sure that the police would definitely not be able to find him.
Even if the entire villa was overturned, there would probably be no result.
"A straw?"
Li Ze's words attracted everyone's attention.
A new direction opened up in the minds of Fu Xiaojun and the others.
Immediately, they understood.
That's right.
A straw!
It wasn't a syringe, nor was it the whole milk tea.
Shen Wendong had plenty of time to prepare the same straw as the milk tea shop.
As long as he could secretly swap them without anyone noticing and then hand them over to Xu Hongwen…
Without any precautions, Xu Hongwen would die immediately after drinking it.
The residual potassium cyanide in the straw flowed back into the milk tea cup along the milk tea.
Therefore, the results of the poison test showed that the milk tea was poisoned!
Everyone was thinking about how the murderer poisoned the milk tea. If the poison was injected into the milk tea, they would have forgotten about the tools used to drink the milk tea. A straw!
This was the safest way!
The milk tea cup would not be damaged at all!
Even if it was a tiny needle hole, it would not exist and would be very difficult to investigate.
Countless eyes looked at Shen Wendong.
Shen Wendong was expressionless as if he did not hear Li Ze's words.
Li Ze looked at him and said slowly,"You're quite smart. It seems that you've made sufficient preparations."?”
Shen Wendong remained silent and refused to respond. His expression did not change at all.
Li Ze retracted his gaze.
He knew that Shen Wendong would never admit it without conclusive evidence.
"Watch him."
At this moment, Li Ze stood up.
"Zirui, come with me."
With that, he walked into the villa.
Xia Zirui quickly followed.
Fu Xiaojun hesitated for a moment before chasing after him.
She really wanted to know how Li Ze would investigate and what his basis was.
For her personal growth, the process was far more important than the outcome.
If Shen Wendong had really prepared a straw in advance, then where did the delivery go?
There were only ten of them.
Where was the 11th branch hidden?
Li Ze went straight to the bathroom.
The bathroom was not small. It was even larger than the master bedroom of an ordinary building.
The interior was beautifully decorated and filled with fragrance.
The smell of the ocean made people feel happy.
It had to be said that Chen Hua's villa was very luxurious. Every detail was done perfectly.
"Is this the only washroom?" Li Ze asked after a quick glance.”
Behind him, Xia Zirui said,"There are two more upstairs."”
"There are three washrooms in the villa.”
"Captain, you suspect that Shen Wendong threw the straw into the sewer?”
Li Ze did not confirm or deny it.
He looked around and pointed at the bathroom.""Let's go and take a look at the floor drain design."
"Alright."
Xia Zirui nodded and immediately understood what Li Ze meant. He walked into the bathroom.
After Xia Zirui entered the bathroom, Fu Xiaojun stepped forward and said,""Captain, it seems like this is the only possibility.”
Li Ze nodded." Wu Kang and his men searched the entire villa, but they didn't find anything. It's not that they didn't find anything, but they really didn't find anything."”
"Shen Wendong is very smart and cautious.”
"He wouldn't leave an extra straw with ironclad evidence in the villa.”
"Once we find it, we'll lose everything."
"Therefore, he will definitely throw it away or destroy it.”
" Throw it away…" Fu Xiaojun glanced at the bathroom and said,""If he really threw it into the sewers, what should we do?”
Li Ze narrowed his eyes.”
Fu Xiaojun's expression changed when she heard this. That's not a small project."
"And it has been more than ten hours now. If Shen Wendong really threw the straw into the sewer, he would probably be in the manure pit now.”
"Then let's pump the manure pit!" Li Ze said calmly.”
"Compared to a murder case, all the manpower and resources are worth it.”
Fu Xiaojun fell silent and nodded.
Not long after, Tong Xuan walked out of the bathroom.
Li Ze looked at him.
"Captain, I've checked it," Tong Xuan said.”
"The bathroom floor drain is designed with a round hole, but the diameter is very small. It can't accommodate a milk tea straw.”
"Can you open it?"
The floor drain in the bathroom could usually be opened to prevent the hair from blocking after the shower.
"I can, but I need tools." Tong Xuan nodded.”
"The floor drain is very exquisitely designed. Under normal circumstances, it won't cause blockage, so it can't be easily opened.”
"I checked carefully just now. There are no traces of movement.”
"Captain, Shen Wendong probably doesn't have time to do this, right?" Fu Xiaojun asked. It's too dangerous."
"Besides, where is he going to find tools?”
" Shen Wendong is in the circle of nine people," Li Ze muttered." He used to gather often. It's definitely not his first time coming to this villa."”
"He should be familiar with the washroom here.”
"We can't rule out the possibility of making preparations in advance.”
"Zirui, go check the other washrooms and see if the floor drain has been tampered with.”
"Yes, sir!"
Xia Zirui nodded and turned to leave.
After Xia Zirui left, Li Ze started strolling around the washroom, carefully checking every corner.
To destroy evidence, the washroom was definitely the best choice.
Therefore, he believed that Shen Wendong had definitely been here.
Xia Zirui moved quickly and returned five minutes later.
"Captain, we've checked. There are no traces of movement.”
Fu Xiaojun looked at Li Ze.
At this moment, Li Ze was lying in front of the sink, carefully examining the water leak, thinking about the possibility of stuffing the straw in.
In the end, he ruled it out.
The milk tea that Xu Hongwen was drinking was a high-concentration drink with pearls in the grains, so the straw was very thick and long.
It was possible to flush it away from here, but it was not the safest choice.
Retracting his gaze, Li Ze looked left and right and looked at the toilet bowl.
He strode over and stared at the toilet bowl in a daze.
"Captain, the structure of the toilet bowl can't flush away the straw.”
Fu Xiaojun said subconsciously.
Li Ze didn't respond. He looked at the toilet in front of him quietly, and his eyes were a little absent-minded.
" It's true that we can't wash away the complete straw," he said after a while." But what if it's…a fragment?"”
