"Madam, this is my business card. I need to save people now. If there is any problem, I can talk later or marry my office directly, but please don't delay saving people." Lin Feng took out a business card and handed it over, and then said very seriously.

"Conan, save people. If something goes wrong, it's mine," Lin Feng said.

"Yes!" Conan nodded, then poured the antidote into the man's mouth.

Then a group of people looked at the man, hoping to see a miracle.

After a short time, the man opened his eyes. Although his face was still ugly and his breathing was not very stable, at least he could open his eyes.

"Great, this medicine really works!" the woman cried when she saw the man wake up.

"It's not a happy time. At present, it only alleviates the symptoms of poisoning, but it still needs to be sent to the hospital for treatment, otherwise black is really prone to problems," Lin Feng said.

"Yes, for the sake of safety, we still have to send the uncle to the hospital for treatment, but we can't all go, because one of us is the murderer," Conan said grimly.

"What? Stop joking, OK? How can we be killers? You know, we are all good friends. Moreover, we often come fishing. How can we poison?"

"Yes, we are good friends."

The victim's friends denied it.

"No way, there are only us at the scene, and if we are friends, we may also become murderers. Therefore, the only people who can send this uncle to the hospital are those who are not suspected, and we are all strangers, which is not suspected in theory. Therefore, I think Dr. Ali should be allowed to send people," Conan said.

"What? Let the old man go? Are you kidding? We don't know him?" the victim's friend jumped out.

"I think this old man is the safest. He seems harmless to humans and animals. Moreover, I think you two are really suspected, especially this gentleman," Lin Feng said.

"By the way, I forgot to introduce it. In fact, I'm a policeman. This is my police manual." Lin Feng took out the certificate from a scroll and said.

"Really a policeman?" the two men carefully checked Lin Feng's certificate and said.

"Yes, the police rank is the chief of the police station. The special adviser of the police station has the power to deal with most cases," Lin Feng said after taking back his certificate.

"But, but you are the president of a firm!" the two suspects looked at each other and then said.

"It doesn't matter. You just need to know my identity. There's no problem." Lin Feng said with a smile.

"Then, please introduce yourself. I need to hear your testimony." Lin Feng took out a book and said.

Conan was stunned in an instant. Is there such an operation? Wouldn't it be very convenient to handle the case?

In an instant, Conan was autistic. Unexpectedly, Lin Feng still had such an operation. Why didn't he think of it before.

"My name is Baiyin Tongzi. What is poisoned is my ex husband Jiangjida Zhi." Baiyin Tongzi said.

After listening to the introduction of Baiyin Tongzi, Lin Feng couldn't help looking at her. At first, he thought it was a friend of the victim. Unexpectedly, it was an ex-wife, and his feelings could be so good. Isn't it good not to divorce?

"My name is jingufeng man. We have been good friends for many years and often come fishing," said jingufeng man.

"Well, since the three are good friends, do you have any special behavior when fishing, or do you have any contradiction with the victim?" Lin Feng asked while recording.

"No, we have a very good relationship. We often go fishing and drink together, so there is no contradiction at all, so there may be no hatred and killing." the man of jingufeng smiled and said.

"Yes, our relationship has always been very good, so there is no possibility of revenge," said Bai Yintong.

"In this case, we can only find clues from these traces on the scene. Then, please wait a moment, and I will collect evidence on the scene." Lin Feng closed his book and searched it.

The two men also cooperated very well. Without any other behavior, they sat down and found a place to sit down. At this time, the victim was sent to the boat.

"Conan, have you found anything? I think there may be something hidden in it. Moreover, Mr. Jingu may be a gangster." Lin Feng whispered in Conan's ear.

"I think so too, but now we have no evidence. We can only talk about it after we find the evidence." Conan nodded.

"However, the three people were still very far away at that time, and there was no possibility of poisoning. However, did we have any motivation to poison, so the murderer could only be one of them, and Mr. Jingu was very suspected." Conan looked at the two people and said.

"Well, did you find anything?" Lin Feng asked.

"I just found a small trace on Mr. Dazhi's hand, which may be the trace of the fishing line, but it can't be regarded as evidence, because we didn't find the fishing line." Conan said bitterly.

"What's the use of finding the fishing line? Look here, there are fishermen everywhere. God knows who has broken the fishing line and floated here or was blown down here by the wind." Lin Feng said, pointing to the fishing line in the sea.

"What you said is reasonable..." Conan nodded approvingly, but he stopped halfway.

"No, maybe we don't need the fishing line as evidence. I think even if we find the fishing line, we can't identify the components of the toxin, and even the trace of the murderer is gone, because the sea water will wash away all the evidence." Conan's glasses lit up when he spoke.

"Really? You found the evidence?" Lin Feng looked at Conan curiously and said.

"There is no direct evidence, but there are always some clues. Next, I need to contact Dr. Ali to see if he has any clues," Conan said.

"Well, call Dr. Ali," Lin Feng nodded.

So Conan ran to a place not far away to make a phone call. He needed to confirm some information about the victim with Dr. Ali.

Conan came back a few minutes later. He got the latest news and solved all the puzzles at the same time.

"How, can you confirm who the murderer is?" Lin Feng asked curiously.

"Basically no problem."
