Abusive pet concubine!Marry a traitor!The eldest daughter-in-law of the Hou family will be widowed a

moment.

When Gu Nanshan took out the silver needle, Prince Gong couldn't help but exclaimed, "The silver needle has turned black, it has really turned black."

Who the hell could have thought of this.

The poison can still be so potent.

This is neither poisonous nor that. If the two are mixed together, they will become highly poisonous.

This is something Gu Nanshan couldn't even imagine.

"It's great, my stability is finally saved." Prince Gong patted his thigh excitedly, and he carefully picked up the pot of tea and the small jar of lychee honey.

"Huayang County Master, thank you very much. You can come to me at any time to fulfill your promise." After saying these words, wind blew under his feet.

After Prince Gong left, Gu Nazhi checked all the lychee honey one by one.

Every jar of lychee honey has been tampered with.

Gu Nanshan was curious, "Zhizhi, what exactly did they add to the lychee honey?"

Gu Nazhi didn't know either, "Brother, even if I smell all kinds of spices in the world, I have never smelled this kind of smell. Otherwise, how could I not know until now that they had tampered with the lychee honey?"

Now she just hopes that the imperial doctor can find out and successfully detoxify Princess Anding's body.

The people Gu Nanshan sent out to investigate Mu Ci quickly returned.

Sure enough, Mu Ci prefers sweets. She also has a habit of always adding honey to her tea. Moreover, her preference is not a secret. Not to mention that many people in the Mu family know about it, including the noble ladies who are close to her.

Who would have thought that her humble hobby would become someone else's weapon to kill her.

"Zhizhi, thank you. Your Majesty gave us three days to solve the case. If we can't solve the case... luckily for you, otherwise we might not even be able to find out how the murderer poisoned us." This time, Zhizhi really helped them. Very busy.

"Brother, you're making a fool of yourself when you say this." Helping brother is what she should do, not to mention that she also got huge benefits.

"Let's go! Accompany me to the prison of the Ministry of Punishment. Although the smell is very light, it is more durable. Once it is contaminated, it will last for a long time. There will be no such thing in the lychee honey from Cui's house. Yes, it must have been added later. We have to be prepared with both hands. If the imperial doctor still cannot find out what kind of poison it is, we can only place our hope on the person who poisoned it." Gu Nanzhi was thinking very much. Zhou Quan, the imperial doctor is good at treating diseases. The toxicity of the lychee honey with added ingredients has not been tested. Is it because the toxicity evaporates when exposed to heat or reacts with the tea? If you want to find out this matter, you need to It takes trial and error.

And it all takes time.

Now is the time Princess Pingping needs the most.

Gu Nanshan helped Gu Nanzhi get into the carriage, and the carriage went straight to the prison of the Criminal Department.

Linglong has already passed this news back.

Xie Ni's brows relaxed and he smiled. Zhizhi is so awesome. The point is, this is his little girl.

Huo Cen was a little worried, "Sir, since the girl has found out the poison they used, there is only one step left to find out the person who poisoned it. I am afraid that the prince will jump over the wall and attack the girl and Mr. Gu on the road, but we need to send another How many people are there to protect them?”

"No need, everything is too much and too little is too much. The prince knows this truth very well. He has already taken action once today, and he will definitely not take action again, otherwise it will appear too deliberate. Besides, since he dared to use those two people, he had already kept a back-up plan, then It's okay if the two of them are not found out. Once they are found out, they will either commit suicide by taking poison or killing themselves. Maybe they will bite Cui Yao back before they die." Xie Ni knew the prince's character best.

Huo Cen asked again, "Sir, since we already knew who the prince's people were, why didn't we tell Mr. Gu and ask our subordinates to make arrangements in advance to prevent them from committing suicide? Only in this way can we leave witnesses. If they stand up and testify against the prince, how can we do it?" Isn’t it better?”

Xie Ni didn't take it seriously, "Do you know how to deal with a suspicious person?"

霍岑摇头，他知道个屁呀！

谢逆轻声道：“那就是不要给他确切的答案，所有的事都要做成似是而非，让他去想，让他去猜，他越想疑心便越重，两只眼睛就会死死盯着太子，如此一来还怕他找不到太子的错处吗？”

Hotzen, "..."

He couldn't help but gasped.

The adults are real dogs...

No wonder he always works too hard and never gets his salary!

The brother and sister soon arrived at the Penal Department Prison.

On the way, Gu Nanshan also took Gu Nanzhi back to Gu's house and found her a suit of clothes worn by the prison guards of the Criminal Department. Zhi Zhi was already eye-catching enough now, and it was better to do less than to do more.

She lowered her eyebrows and followed Gu Nanshan.

"Interrogate everyone in the Cui family again." Gu Nanshan ordered in a deep voice. He asked Gu Nanzhi to stand at the door of the interrogation room. As long as those people passed in front of her, she could smell their scent clearly. Without being conspicuous, you can approach those people naturally.

The first person to be interrogated was Cui Yao's personal maid.

After smelling her scent, Gu Nazhi calmly shook his head at Gu Nanshan.

Gu Nanshan knew it wasn't her.

The second, no.

The third one, Gu Nanzhi, also shook his head.

Gu Nanshan was a little anxious. Could it be that the murderer had escaped?

It wasn't until the sixth person passed by Gu Nanzhi that she suddenly smelled a familiar smell, that strange fragrance.

Brother, it's her!

She glanced at Gu Nanshan. Gu Nanshan didn't alert anyone. There was no guarantee that she didn't have any accomplices. She had to go through everyone.

After the maids and women who served on the boat, it was the turn of the guards on the boat.

The first guard passed by Gu Nanzhi, and she raised her eyes to look at Gu Nanshan.

Gu Nanshan knew it well and had already identified two people, but he didn't know if there were any accomplices.

The last one is Cui Yao.

Gu Nanzhi always knew that there was nothing wrong with Cui Yao. Firstly, she and Mu Ci were close friends, and secondly, no one would be stupid enough to commit murder on their own territory and cause trouble for themselves.

After only staying in the prison of the Ministry of Punishment for a few hours, Cui Yao was like a flower beaten by frost, looking wilted. She was now thirsty and hungry, and she didn't even have the strength to speak.

Cui Yao didn't notice Gu Nanzhi.

After checking everyone, only two people were found, a rough maid and an inconspicuous guard. Who would have thought that they were the ones who poisoned the lychee honey.

Gu Nanshan first asked someone to bring the rough maid to the interrogation room, and interrogated her first, "Tell me, why did you poison the lychee honey, what kind of poison was it, and who ordered you? "

After catching them, Gu Nanshan asked someone to send Gu Nazhi back.

A trace of surprise flashed in the eyes of the maidservant who was doing the rough job. She denied it like a frightened bird, "Slave, I don't know what the Lord is talking about. What kind of lychee honey? I am poor and have never eaten that kind of good food. So, Even after entering the Cui Mansion, she is just a low-level maid, she can’t even get close to a noble person, so how can she be qualified to come into contact with that kind of thing? Please tell me, sir, I am unjustly accused!”

等她狡辩完，顾南山冷笑了一声，“赵四已经招了，就连背后那人都供出来，若你死咬着不说，只有一个下场，就是被杀人灭口，你以为这就完了吗？还会连累你的家人，陪你一起命丧黄泉，就是死后也不得安生，本官劝你还是乖乖招供，这样兴许还有一条活路。”
