"Poison! The same as the poison that killed Mosk. Lang Xiaobai said. His inference is already an ironclad fact.

It turned out that Agent Wang Lin wanted to enter the infirmary, and just after walking a few steps, he suddenly remembered something and came back. That's exactly what the security guard on duty saw. He entered the detective's room and was in unbearable physical pain. I wanted to go to the infirmary again, but I was dizzy and couldn't tell the direction, so I thought the toilet door was the door of the infirmary, and rushed in, and I never came out. ”

Lang Xiaobai's incisive reasoning is really as if he is in the scene, and he speaks the truth. The detective listened, nodded and praised: "Your logic is very reasonable. But what did Agent Wang Lin remember at that time?"

"Then I don't know. But, Inspector, isn't there a few words written in the memo on your desk? Perhaps it was written by Wang Lin when he was poisoned. Take a look!"

The detective opened the memo and looked at these words seriously, it was indeed left by Wang Lin. A few words are "pay, letter.......

"Fu" should represent the name of a place or a person. Yes, it should be the person's name. Call for ...... The name of the person!"

"Maybe it's the name of Mosk's killer. Wang Lin expected that he would be very unsafe, and he had to write the murderer's name on the memo no matter what, but if he only wrote three words, he would be very poisonous and could not write it completely, hey! Poor kid! ”

The detective looked at Wang Lin's remains a few more times in grief, prayed for him very reverently, sighed deeply, and then called the secretary and security to put Wang Lin's body on the sofa.

The results of the forensic examination were that Wang Lin died due to the poison entering the body, but it was impossible to know the name of the poison without laboratory tests.

When preparing for the autopsy of Wang Lin's body, the security guard on duty walked in with a business card. "Inspector, a gentleman has come to visit you."

The business card reads: Mechanical and electrical technician Fu Yucheng, No. 34 Dongping Street

Fu Yucheng, isn't it exactly ...... The detective said with some distraughtness, "Quick, bring him in!"

An elderly man was brought into the detective's room. I saw that his long unkempt hair hung down to his forehead, his cheeks were sunken, and his eyes were bloodshot, and he looked terrible. His clothes were disheveled, his tie was loose, and he looked tired.

"Are you a detective? Something terrible has befallen me, please help me! Someone is going to kill me, and they are going to kill my son...... What a horrible conspiracy...... The Demon King Who Kills...... Help me...... Save my son......"

The old man, who was trying his best to hold his head high to ask the detective for help, suddenly saw Wang Lin's body on the sofa......

"Oh, dead! Killed! Alas, Mr. Wang Lin was also killed. I'm late, I can't save him, it's too late......"

The old man grabbed his hair with both hands, squatted down and wept bitterly.

"Mr. Fu, please don't be too sad."

The detective helped Fu Yucheng up and said, "You already knew that Agent Wang Lin would be killed?"

"Yes, I've been worried about his safety, so I'm here to tell you, I didn't expect it...... Ay! It's too late!"

"Can you tell me who the murderer is?"

"No, I can't say it yet, I know they did it, but I haven't found conclusive evidence yet."

'They did it', meaning more than one person?"

"Yes, it's two people."

"Are you saying that on this day last month, they killed Mosk? Listen to Agent Wang Lin, on the same day a month later, two more people will be killed, do you mean your father and son?"

"Yes, it's father and son. They'll do it tomorrow night, because tonight they're not quite ready. In order to get the conclusive evidence, I spent a day and set a trap. ”

"What trap?"

Fu Yucheng looked around and said, "It's inconvenient to talk about it here, it's too terrible." ”

After Fu Yucheng came in, Lang Xiaobai never spoke, just kept looking at him. When he saw Fu Yucheng trembling with fright, he asked:

"Mr. Fu Yucheng, is Lu Li your mother?"

The old man hesitated, widened his eyes, and said, "Yes." You...... How do you know my mother's name is Lu Li?"

"Huh?" The detective shouted.

They are looking for Lu Li, the heir to Mosk's estate. "Where's your mother?"

Everyone stared at Fu Yucheng. "No, my mother has died."

"Oh, it's gone."

Lu Li died, and of course the heir to the estate was her son. In this way, Fu Yucheng has the right to inherit this inheritance!

Agent Wang Lin exchanged his life for the heir to Mosk's estate.

However, Lang Xiaobai needed to know more about the situation, and then asked, "Has your mother lived in Dongzhou?"

Fu Yucheng was very uncomfortable, and looked at Lang Xiaobai in confusion:

"Yes, stayed. But...... Why do you ...... Who the hell are you?"

Lang Xiaobai stared at Fu Yucheng intently.

A few seconds later, he suddenly took the chocolate candy with tooth marks and handed it to Fu Yucheng. "Do you have an impression of this thing? Detective Wang Lin brought it back. ”

"Oh...... This ......"

Fu Yucheng's face suddenly turned pale. However, he pretended to be calm and said in a trembling voice, "No...... No! This...... Where did Mr. Wang Lin get this? I...... I ......"

After saying that, beads of sweat oozed from his face, as if he felt very sad.

He stood up and swayed towards the door. As he was about to step out of the detective's room, he turned around and said:

"Goodbye, to-morrow morning I will tell you that this is not the time to speak. I'm gathering some evidence tonight, but you'd better catch the devil, or I'll be killed with my children. Detective, you must catch them. ”

Fu Yu stumbled out as if he had a high fever.

About half an hour after Fu Yucheng left.

Lang Xiaobai took a security guard and hurriedly ran to the street.

"Brother Lang, where are you going?"

"Just follow me!"

Security guard Li Yunshan is Lang Xiaobai's sworn brother and assistant.

Lang Xiaobai told the detective that for Fu Yucheng's safety, he and security guard Li Yunshan lived in the old man's home tonight to protect the old man.
