"If something happened to the old man, who would take over as the factory manager?" Qin Lei asked.

"Of course, I'm choosing one of the two deputy directors..." Chu Xintong replied almost subconsciously, but Chu Xintong stopped by herself after saying halfway through, but turned around and said in disbelief: "Qin Lei, what do you mean?"

Qin Lei said without answering the question, "You think it's impossible!"

"Of course it's impossible! Uncle Wei is a very good person. I have never seen him blush with others even though I have grown up. Uncle Wei is also a comrade-in-arms of Uncle Qin. I don't believe you say he will harm Uncle Qin!" Chu Xintong said directly.

Qin Lei did not agree with Chu Xintong's words, but continued to ask: "What about the other one?"

"Deputy Factory Director Gu..." Chu Xintong paused slightly when she said this, and then whispered: "Deputy Factory Director Gu was transferred from the back. I am not very familiar with him, but I don't believe you said he would poison Uncle Qin!"

"Wait a minute... do you say that the other deputy factory director's surname is Gu?" Qin Lei paused and said, "I'm Gu Guobin?"

"It seems so? How do you know?" Chu Xintong asked in confusion.

However, Qin Lei did not answer but frowned slightly and showed a contemplative look.

Qin Lei has seen the name Gu Guobin. He is on the list of factory directors of Qingshui Heavy Industry. This guy is the next factory director after Qin Lei's biological father died.

Qin Lei does not understand criminal investigation, but in his opinion, since Gu Guobin is the biggest beneficiary of the old man's death, his suspicion is of course the greatest.

"Are you okay?" Chu Xintong looked at Qin Lei with some concern and said.

"It's okay! Go home first!" Qin Lei shook his head. He had limited time and found evidence first. If he really couldn't find it, he could only be tough.

He was secretly ruthless in his heart, but Qin Lei had already followed Chu Xintong back to the small white building of Qin's mother's house.

Chu Xintong took it out and opened the door, but before she could enter, she was stopped by Qin Lei.

"You should come here often, right?" Qin Lei asked.

"Are you almost the same? I will come here every few days." Chu Xintong said.

"Then please help me watch something later. Is there anything that was originally not here!" Qin Lei said.

Chu Xintong nodded but said with some confusion: "Do you think someone will give Uncle Qin something poisonous? But several days have passed. If that person really gave something poisonous, he will definitely find an opportunity to take away the things these days after Uncle Qin is hospitalized, right?"

Of course, Qin Lei knew that Chu Xintong was right, but he had no choice. He was not reincarnated by Detective Ming, so he could only use the stupidest method to do this kind of thing step by step. Even if he knew that the profits of this method were not high, the problem was that he had to have a better solution!

"Look for it first!" Qin Lei said with a tough bullet.

After Qin Lei entered the house, he did not care about Chu Xintong, but went directly to the old man's bedroom.

He remembered that the old man seemed to be found in his bedroom. Qin Lei came over to see if the window was closed and if there were any signs of passive actions.

Qin Lei thought about it carefully and found that there were only a few types of poisoning a person. One is the simplest and most direct one, which is injection!

However, there is no similar record in the medical records found by Qin Lei in 222. It should be noted that in that time and space, the old man and Qin's mother had fainting symptoms at the same time, so the people in the hospital immediately considered that they were poisoned, so they would definitely give priority to finding needle holes. There is no relevant record on the medical records, so this possibility can be temporarily ruled out.

Then you can only consume it through your mouth, nose or skin, that is, you eat poisonous food, inhale, or you may contact items that have been smeared with poison.

Qin Lei asked Chu Xintong to look for things to find these, and Qin Lei checked the windows himself to find out whether someone invaded or poured poison gas into the house.

The old man's bedroom is on the second floor, and there are no signs of climbing or prying on the windows. Although it is not 100% certain, the possibility of poisoning from the windows is greatly reduced.

At this time, Chu Xintong also came in and said, "There are still some leftover noodles soup in the kitchen. Uncle Qin should have made noodles at home on the day he was poisoned, but before he could clean it up, he piled it in the kitchen. Do you really think Uncle Qin was poisoned?"

He was sure of this when he heard the other party ask this, because the two medical records proved that Qin's mother and his wife died together. According to the records, the symptoms were the same as those of the old man. It was a bit too coincidental that the two people had the same disease, so it was probably poisoned.

However, Qin Lei had no way to use it as evidence from another time and space discovery, so he really didn't know how to explain this to Chu Xintong, so he could only say perfunctorily: "I'm just guessing."

It was not surprising to hear Qin Lei say this. Chu Xintong nodded and said, "Uncle Qin's kitchen is too messy and there is no food. Let's go to Sister Wang's house to borrow the kitchen!"

"Sister Wang?" Qin Lei looked at the opponent in confusion.

"Yes! It's the one next to you. Sister Wang is a nurse in our hospital. She is very good at being, so there should be no problem!" Chu Xintong said.

"Nurse? Isn't this the housing of the factory leader?" Qin Lei asked in confusion.

Although the salary between workers and leaders is not much different now, there are still differences in treatment, just like this small single-family building, only the leaders in the factory are eligible to move in, so Qin Lei asked this question when Chu Xintong said that the other party was a nurse.

"Her lover is a senior worker in the factory!" Chu Xintong said as she walked out.

"Oh!" Qin Lei was not surprised when he heard this. In fact, the profession of nurses is definitely a good partner even after thirty or forty years. It is normal for a senior engineer to find a nurse as his wife.

After the two walked out of the room, they immediately came to the door of the house next to them. Chu Xintong stepped forward and knocked on the door while Qin Lei stood on the street and observed the surrounding environment.

This path is very wide. Although there are not many pedestrians coming and going at this time, there is a row of five-story ordinary family areas opposite. People on the other side of the house can clearly see the door here. If you ask from door to door, someone might see the old man being poisoned. Maybe someone would have visited his house on the day he was poisoned!

But if this happens, the workload will be a bit too high. The old man may not be able to wait for so long, so it is better to...

Just as Qin Lei was thinking about how to investigate faster, the door of the room had been opened, and a woman who seemed to be at most thirty years old poked her head out of the door: "Hey, Xiaotong? Did Sister Lou come back with you?"

"Well! Aunt Lou is in the hospital. I want to get some food when I come back, but Aunt Lou's house is a little messy now. It's a bit far away to go back to my house. I wonder if I can cook some food at your house..." Before Chu Xintong finished speaking, the woman opposite said directly:

"What's the matter! Come in quickly, everything is ready, I'll get it for you!"

"Qin Lei!" Seeing that the other party agreed, Chu Xintong immediately turned around and greeted Qin Lei.

But when the woman saw this, she looked at Qin Lei who was walking over quickly with some confusion, and asked, "Is this your boyfriend?"

"Uh...he is Aunt Lou's son." Chu Xintong did not hide Qin Lei's identity.

Hearing this, the woman nodded immediately: "Oh! I know, I know, the young man is so energetic!"

"Hello, Sister Wang! I want to ask, has anyone come to their house the day before your Director Qin fell into a coma?" Qin Lei suddenly asked when he walked to the door.

"What?" Hearing Qin Lei ask such a question inexplicably, the woman called Sister Wang subconsciously looked at Chu Xintong.

Chu Xintong knew what Qin Lei wanted to know, but although she didn't think this method was reliable, she still spoke to Sister Wang and explained: "Qin Lei suspected that Uncle Qin might be poisoned, so..."

"Poisoned?" A scream came from the room, but a middle-aged man who looked over forty years old and obviously had a bald man just went downstairs to hear Chu Xintong's words. His haggard face was filled with a look of fear.

At the same time, Sister Wang said in disbelief: "Impossible? Director Qin is such a good person, who would poison him!"

"We are actually not sure, but we always have to check whether you two families have seen who came that day?" Chu Xintong asked for helping Qin Lei.

"I really didn't pay attention to this." Sister Wang looked at Qin Lei apologetically and then said to Chu Xintong: "You know me, after I go home, I just cook and clean the house, and I don't usually look out, so..."

"I know, I know!" Chu Xintong nodded quickly and turned to Qin Lei and said, "Let's get some food first to send other things to Aunt Lou. I'll talk about it tomorrow!"

However, Qin Lei had no intention of eating and said immediately: "You can make some food, I want to go to the security department to take a look!"

"You want the security department to help you investigate if anyone has visited Uncle Qin's house? But you have no evidence to prove that Uncle Qin was poisoned. I'm afraid the security department will not agree!" Chu Xintong said.

"You have to give it a try!" Qin Lei thought about it. As the saying goes, money can make the devil push the mill. At worst, he can spend some money. He doesn't believe he can't find anyone to help.

However, just as Qin Lei turned around and was about to leave, Sister Wang suddenly spoke, "That... I'm not sure!"

"What?" Qin Lei asked subconsciously.

"Just now, I suddenly thought that when I came back to clean the window that day, I seemed to see the factory manager Gu passing by, but I was busy at that time, so I didn't look carefully if he came to Director Qin's house." Sister Wang said.

"Gu Guobin?" Qin Lei said with a serious expression.

"Yes!" Sister Wang nodded, then shook her head and said, "But it's impossible. Director Gu doesn't look like a person who can poison people no matter how you look. Did you guess wrong?"

After hearing this, Qin Lei pondered for a while and said in a low voice: "You always have to take a gamble if you guess wrong, you are better than having no clues!"
