"Just recently, a few days ago......"

Su Jin raised her head, glanced at Shan Chenxun, and she asked again, "Are all the barrels here?" ”

Master Liu took a look, "It should be all here......"

He's not sure, and besides, he doesn't usually pay attention to these details.

"Not sure?" Shan Chenxun frowned.

Master Liu shook his head: "This has to be asked to Manager Qin, he is responsible, he should be clear." ”

"When will Manager Qin come back?" Yuan Ke walked over with a notebook.

"It is estimated that it will take two more days, and this time it will take a long time, and Cheng Fangfang will be responsible for his work."

"Cheng Fangfang? Manager Yin trusts her a lot......" Yuan Ke said casually.

"This kind of trivial matter needs to be appointed by Manager Yin, Manager Qin has this right, he can hand it over to whoever he wants! Fang Fang's popularity is good, don't talk about Manager Qin, everyone is looking for her if they have anything......"

Master Liu talked eloquently, and his words were all praises for Cheng Fangfang, "Fang Fang is diligent and efficient, Manager Qin has any important work to give her, every time she is praised by the guests, she has been one of the top ten employees almost every year in recent years!" An excellent representative of our cleaning department! ”

Shan Chenxun motioned to Yuan Ke and asked her to continue questioning, while he walked back to Su Jin's side.

The man asked in a low voice: "Can this material be filled with sulfuric acid?" ”

"Iron, of course." Su Jin explained, "The reaction between iron and sulfuric acid will form a protective substance on the surface to avoid corrosion, in addition to ceramics, glass and other utensils, iron containers are also a good tool for containing sulfuric acid." ”

"A bucket is about four or five pounds." Shan Chenxun weighed his weight, "It's not a problem to load a dozen bottles on the work car, not to mention that there are towels on it, so it won't be noticeable at all." ”

Su Jin looked at the work car and said in a low voice: "As long as you find evidence that Cheng Fangfang appeared on August 2nd......"

Shan Chenxun kept a calm face, didn't say a word, and put down the bucket silently.

After the questioning, the three returned to the conference room.

Soon, Lao Yang and others also came back, and they didn't find anything suspicious.

"Why aren't there cameras in the corridors of the guest rooms?" Yuan Ke questioned.

"There are at the gate and in the elevator, but there is no other place, saying that it is to protect the privacy of guests." Alpine description.

"Didn't find Cheng Fangfang in the surveillance?" Seeing Gao Shan nodding, Yuan Ke continued: "Since she didn't find out, it shouldn't have been her doing, right?" Do you think, if Cheng Fangfang killed Anna, what was her purpose? It must be to avenge her son, but she just found out about her son's violation, which makes a little unreasonable......"

"Xiao Yuan, there is progress!" Lao Yang complimented her and gave her a thumbs up.

"So, Cheng Fangfang's reaction may be pretended? She already knew about her son's violation? Li Bai recalled that two hours ago, Cheng Fangfang cried and grabbed the ground, and he really couldn't see that it was fake.

Shan Chenxun knocked on the table, "Don't speculate, investigate the case and talk about evidence." ”

"Yes." Li Bai nodded and didn't say anything more.

The conference room fell silent, and within a few minutes, Shan Chenxun received a call from Gu Sir, who told him, "Forensic doctor Su took a sample of sulfuric acid in the bathtub for me, and after testing, it was found that in addition to sulfuric acid and a small amount of water, some chemical components were also found, which are mainly used to clean dirt. ”

"Detergent?"

"Yes, it's all found in powerful cleaners that remove grease."

"Hmm...... Got it. Shan Chenxun's face was solemn, and the cold air in his eyes was spreading.

He took the line and remained silent for a long time.
