Cheng E's action is very strong, and he immediately gathered his subordinates and secretly went to Dong Huan's residence to make a secret arrest.

Yang Shan was not idle, and immediately sent someone to secretly keep an eye on Zhang Ran and monitor his every move.

Zhou Zheng took Yue Xiaoyue to visit Hu Tu, and the two exchanged their respective gains, and after that, Zhou Zheng asked Hu Tu to arrange Yue Xiaoyue into the Dianlu Hall to be an ordinary priest.

Yue Xiaoyue's task was easy, but it was also difficult. Her main purpose is to monitor the actions of Zhangwu and Xingliu, and get close to them to see if she can get more clues about the case file.

Hu Tu has a good personal relationship with Yue Xiaoyue's sister Yue Ruyue's master, Xuantong, so it is easy to find this excuse and arrange Yue Xiaoyue into it quietly. Huang Cheng also has a good relationship with Xuantong, so he naturally takes good care of Yue Xiaoyue, and specially asks the old man Zhangwu and Xingliu to take this newcomer well.

After arranging all this, Zhou Zhengcai remembered that it was time to find time to go to Jiuhua Mountain to pick up Yun Ling and go home. There are too many things in this section, and before I know it, I have left Yun Ling in Jiuhua Mountain for more than ten days.

Although Yun Chi was involved in the case, the Dao Heart of Jiuhua Mountain knew that Zhou Zheng had been busy with the case, and he would definitely tell Yun Ling. However, his daughter-in-law still has to hurt herself, so she has to go in person, explain the recent situation to Yun Ling, and take her home.

Zhou Zheng went to the street to buy some gifts, planning to leave early the next morning. However, as soon as he returned to the residence, the chairs were not hot, so Cheng E hurriedly broke in.

"Zhenjun, it's not good! Dong Huan is dead! ”

"Quick! Take me to see it! Wait, notify Yang Shan, and arrest Zhang Ran immediately! ”

"Do you suspect it's Zhang Ran?"

"Nope! If Zhang Ran is also a traitor, arrest him to protect him! We can't break this line! ”

"Understood!" Cheng E took Zhou Zheng to the place of the accident, and arranged for his subordinates to quickly notify Yang Shan.

Dong Huan died in a winery, which is also a place he frequented.

Cheng E led the people to break into Dong Huan's house but pounced, and when he asked, he learned that Dong Huan had not come back after he was on duty.

Cheng E immediately took people to search for several places where Dong Huan often went, and sure enough, he saw Dong Huan pouring himself a drink in this winery.

In order not to startle the snake, Cheng E went in alone, and let his subordinates ambush around the periphery of the winery.

Seeing Cheng E, Dong Huan was not surprised at all, and asked the shopkeeper to take out another cup and put it in front of Cheng E.

"I know it's going to be sooner or later! I just didn't expect it to be so soon! Come, envoy, have a drink with me! ”

Cheng E also missed the old love, and couldn't bear to brush his mind, so he sat down and drank a few glasses with him.

"Why?"

"Why?" Dong Huan smiled bitterly, "It's not that you don't know the situation in my family!" I am a counselor, but I can't even support my wife and children at home, so I can make them hungry and full! ”

"Alas!" Cheng E sighed. He knew that Dong Huan was a filial son. Dong Huan's mortal father is an out-and-out rotten gambler, and he owes a lot of debts all day long. Dong Huan didn't dare to know the law and break the law, so he relied on his identity as the law and punishment department to punish those creditors, so he had to use most of his own money to pay off his father's debts.

Who knows, his father didn't let him live in peace everywhere, more than half a year ago, his father gambled in a hurry, and burned down people's gambling houses, and burned more than a dozen houses one after another, burning seven or eight people to death. The government sentenced him to death on the spot.

For this matter, Dong Huan begged a lot of people. But this kind of human life is at stake, and it involves mortal affairs, and the Department of Law and Punishment really can't interfere. Everyone couldn't help and comforted Dong Huan for a long time.

"But I can't watch my father get killed! You don't have anyone to help me, but that person can! Dong Huan directly picked up the flask and poured a large sip of wine, "That person's request is very simple, just let me answer a few questions." Just a few questions, I can change my father's life! You say, if it were you, would you do it? Haha, I do! I'll do it! ”

Dong Huan took another sip, "I didn't hurt anyone!" What I say is something that others can know! Even if I don't say it, people will tell him! I have a clear conscience! I'm worthy of my conscience! ”

Dong Huan picked up the flask and drank it again, and then suddenly cried out loud, "I just want to save my father!" No matter how he is, he's also my father! I'm going to save my dad! ”

Seeing that Dong Huan was drunk, Cheng E stepped forward to support him, "Tell me, who is that person?" ”

"I can't say!" Dong Huan looked at Cheng E painfully, "I really can't say it!" Otherwise, my dad won't survive! My family won't survive either! Envoy, brother! For the sake of our friendship for many years, you give me a good time and kill me! ”

"What nonsense?" Cheng E shook Dong Huan's body violently, "You are sober!" Only by catching that person will your family be completely safe! Tell me, who is he? ”

"You can't catch him!" Dong Huan has made up his mind, and he will not say who that person is even if he dies. He pushed Cheng E away, staggered and poured a big sip of wine, "Brother, when I finish drinking this pot of wine, you can take me away again!" ”

However, suddenly, Dong Huan showed an incredible expression, he suddenly felt angina in his heart and bleeding from his seven orifices, "He, he still doesn't trust me!" I'm so stupid! Cheng E, he..."

Dong Huan fell to the ground and died, and he couldn't say a word!

Squatting next to Dong Huan's corpse, Zhou Zheng listened carefully to the report.

"Zhenjun, the toxicity of this poison is very strong, and there are many kinds of poisons mixed together, but the main ingredient can be determined to be golden aconite. It's just that this kind of poison is extremely rare here, and it is generally produced in the Kunlun Void Demon Clan's realm. ”

"Are you sure!"

"Subordinates can be sure! It's just that the other ingredients still need to go back and inspect again. ”

"Good! Be sure to check carefully, and it's best to test all the ingredients! ”

"Yes! The subordinates retired. ”

"Zhenjun," after waiting for the pretender to retreat, Cheng E stepped forward to admit his mistake with a humble heart, "It's all my fault, if I don't think about the feelings and arrest me directly, maybe..."

"How can I blame you for this? Before you came, someone had poisoned him. It's just that when was it poisoned? ”

Just now, he had already checked that there was no poison in the wine and food, and Dong Huan came directly to the tavern after the next duty, and he had never been to other places in the middle. In other words, Dong Huan was poisoned in the Department of Law and Punishment.

It's just that the person who poisoned the person had a very accurate grasp of the time, and if Dong Huan hadn't stopped at the winery, he would definitely have been poisoned after dinner at home, which would add more trouble to finding the cause of his death.

Zhou Zheng suddenly snorted, "Cheng E, you go to my office immediately, find me inch by inch, and see if there are any magic circles or charms that you are eavesdropping." ”

Cheng E was also startled when he heard this, and he hurriedly led people back to the Law and Punishment Division.

Seeing a group of people surrounding him, Zhang Ran was puzzled. He looked at Yang Shan, who was leading the team, and asked puzzledly. "Envoy, what do you mean by that?"

"What do you mean?" Yang Shan sneered, "Don't you know yourself?" Dong Huan died, how did he die? You should know best, right? ”

"What? Dong Huan is dead? Zhang Ran was taken aback. He instantly understood why these people were arresting him.

He didn't resist, he chose to be arrested, but when he was escorted past Yang Shan, he said sincerely, "The murderer is really not me!" You must beware, since he started to kill Dong Huan, I estimate that those people will soon be solved by him. You must stop him! ”

Yang Shan's heart froze, "Who is he?" ”

Zhang Ran shook his head, "I don't know either." However, you'd better protect Zhangwu and Xingjiu! ”

Yang Shan couldn't figure out the meaning of Zhang Ran's words for a while, and he didn't know whether what Zhang Ran said was true or false. But in order to be as foolproof as possible, Yang Shan still sent a few of his subordinates to secretly protect Zhangwu and Xingliu.

Until late at night, his subordinates reported that Zhangwu and Xingliu had gone to bed and slept peacefully, and there was no abnormal behavior. Only then did Yang Shan put his mind at ease. However, before he could breathe, another piece of news came, and he almost fell to the ground.

Zhang Ran is dead! Like Dong Huan's symptoms, he died of poisoning!

Zhang Ran is under heavy guard! Who has the power to commit murder under everyone's noses?

Yang Shan immediately told Zhou Zheng and asked Zhou Zheng for guilt! Zhou Zheng was afraid that Zhang Ran would be killed, so he asked Yang Shan to arrest and protect him in time, but he didn't expect that Yang Shan finally messed up this matter, how could he not regret it?

"Did you do it? Let's go! Don't be stunned! Now is not the time to hold accountable! Hurry up and catch the real culprit! Zhou Zheng raised his feet and walked first, and Yang Shan hurriedly followed behind him and rushed to the prison of the Department of Law and Punishment together.

In the prison, Hu Tu had also arrived, and in front of him were kneeling with the prison guard delivering food and two guards.

Seeing Zhou Zheng coming, Hu Tu asked him to sit aside and continue the interrogation.

"You delivered the meal in the evening?"

"It's a villain. However, the villain was completely in accordance with the rules, and he gave it to Zhang Ran after tasting everything. ”

"Is there a witness?"

"Yes, yes, a few of them saw it."

The two guards also nodded hurriedly, "Zhenjun, we watched him eat, and we all ate it, and when there was no problem, we sent the food to the prison." No, the food is poisonous. Otherwise, a few of us would have died! ”

Hu Tu looked at Zhou Zheng, "Brother, what do you think?" ”

"Brother Hu, it's not them! Let's put it on! ”

Hu Tu waved his hand at the three people, "Go down!" ”

The three of them thanked Hu Tu and Zhou Zheng for their gratitude and retired.

"I have already interrogated it just now, after Zhang Ran was put in the cell, no one has had contact with him alone, how did this poison come about?"

"I estimate that long before Zhang Ran was arrested, he had already been poisoned. Same as Dong Huan. The location of the poisoning is in the Department of Law and Punishment, and the person who poisoned should also be someone from our Department of Law and Punishment, and he has a good relationship with the two of them! I've already asked Cheng E to check. ”

Hu Tu slapped the table heavily, "This traitor is too rampant!" Brother, can there be anyone who doubts? ”

Zhou Zheng shook his head, "There are too few clues, it's too early to draw conclusions!" ”

At this time, he came over, "The two true gentlemen, Zhang Ranzhong's poison is the same as Dong Huan's, and the main medicine is golden aconite." The two people should have been poisoned at the same time, and Dong Huan was poisoned because of heavy drinking, which caused the poison to attack early. Zhang Ran didn't drink alcohol, and the amount of poison in it was small, so he had a seizure at midnight. ”

"Zuo, you said that the golden aconitum is highly toxic, why does it take so long to be poisoned?" Zhou Zheng asked.

"Back to Zhenjun, I've been researching this poison since I left the brewery, and I found nettles in it. Nettles are also highly toxic, and the two poisons offset each other, and the poisoned person will not feel uncomfortable. However, the amount of nettle is not large, and once it is consumed, the toxicity of Aconitum aconitum cannot be neutralized, and it can directly cause poisoning. ”

Zhou Zheng nodded, "The means are clever!" ”

He couldn't help but think of Lin Shu in his mind, that guy was also a master of poisoning. Such a poison, Lin Shu is indeed capable of making. Could it be him? He's hiding in the Judicial Division?

However, Zhou Zheng immediately overturned this idea. If it was really Linshu, it would be impossible for him to start laying out this game more than a year ago, and at the same time as laying out this game, he was still laying out in Luqi Town. He's stunning! Besides, Zhou Zheng didn't think he had such great ability!

So who is this person?

Zhou Zheng told Hu Tu the suspicions in his heart, and Hu Tu also felt that Lin Shu was unlikely! However, both of them thought of a problem, that is, this traitor had a close relationship with the demon clan, at least he had close contact with the demon clan of Kunlun Xu or Luqi Town.

Because based on the secret history content provided by Dong Huan alone, it is impossible for this person to easily catch a dream-eating tapir that can forbid arts, nor will he get the golden aconitum poison that only Kunlun Xuan has.

The only person who can have such a relationship with the demon clan is the person of the Hunting Division! Moreover, is it still middle and high-level? Could it be that Dong Huan did all these things?

However, if it is said that the poison of the golden aconitum is obtained, Dong Huan may have a channel. However, catching a dream-eating tapir, Dong Huan's cultivation will definitely not be able to do it alone! It must be done by the combined efforts of at least two or more people who are extremely familiar with the life characteristics of the Dream Eater Tapir!

Could it be that the Patrol Division still has Dong Huan's accomplices?

The affairs of the Pawn Division have not been sorted out, and there is a problem within the Patrol Division, and both of them can't help but be big.

Zhou Zheng suggested that he should report to Wen Ruyuan immediately, and it was best to hand it over to Fushun Division to investigate. Hu Tu hesitated for a moment and stopped.

"Brother, you and the master trust me, and the master and I naturally trust the brother's character. Since the two of us can't be traitors, as long as the two of us preside over it, no matter that Si Cha can find out the matter!

Besides, we've been checking for so long, and we're almost about to catch that person's fox tail! Otherwise, he wouldn't have jumped over the wall and killed two people in a row! At this time, if you hand it over to a new person to investigate, it will give this traitor a chance! I thought, why don't I go to the master to report this matter, hard brother, continue to bite the clues, and I will definitely find out that guy! ”

Zhou Zheng bowed deeply, "Brother Xie Hu trusts!" Brother, do your best to catch this thief! ”

The two said goodbye. Hu Tu went to find the master Wen Ruyuan, and Zhou Zhengze returned to his office.

Cheng E searched out a small array disk of monitoring here, placed it on the top of the bookcase, and couldn't find it at all if he didn't pay attention.

This array disk is not large, and the transmission distance is not too far. Cheng E led people to search Zhou Zheng's house from house to house, and finally found clues in a special secret room of the Patrol Division.

There are one or two of these chambers in each department, and they are mainly used for secret deliberations or for the secret storage of valuables. There are layers of mechanisms inside and outside the room, and they are extremely secretive. Very few people know about this secret room and how to open it.

Since that person is eavesdropping here, his identity will not be among those people.

Cheng E was very confident and felt that he could almost catch the real murderer this time. However, the result left him dumbfounded. Including him and Yang Shan, several people who can know the secret room have alibi certificates, and they all have human witnesses, and they have all been verified one by one, and they are indeed not lying.

The only one who has not been verified is Counselor Dong Huan. Could it be that Dong Huan overheard Zhou Zheng's secret conversation and found that when everyone began to doubt himself, Dong Huan committed suicide by taking poison?

This is obviously unreasonable, and it is also very different from Dong Huan's performance before his death. What's more, why did Dong Huan kill Zhang Ran? Are they really complicit?

Perhaps, there is another possibility, that is, Dong Huan, who overheard the conversation, reported to the person behind him in time, and then was poisoned by that person.

However, timing doesn't make sense. The decision to arrest Dong Huan was Zhou Zheng's final decision, and Cheng E's actions were also very fast. Less than two quarters of an hour in between.

In such a short time, if it is, Dong Huan will report the news, and then he will be poisoned, and it will be too late in time. Besides, Zhang Ran, what's the situation? How could he be poisoned with Dong Huan?
