Lingyue looked at all kinds of torture instruments around her, she was unbearable and afraid in her heart, and her fragile appearance made people want to pity her even more.

This time, the eldest grandson did not "pity the fragrance and cherish the jade", and asked in a cold tone, "Lingyue, are you guilty?"

Upon hearing this, Lingyue immediately fell to her knees in fright, "Your Excellency...... I don't know what crime the slave has committed......

But the eldest grandson didn't listen to Lingyue at all, and his voice didn't fluctuate in the slightest, like a cold machine.

"Lingyue, on September 10th, you were in charge of serving the North Study, and you saw that Tang Huai'an hadn't rested at night, so you went to serve him tea and incense, am I right?"

Lingyue looked down at the ground, her body trembled a little, and she didn't dare to look up at her eldest grandson.

"Answer my question!"

Lingyue shuddered with fright, "Yes...... Yes."

"Good! Then let me ask you, what kind of tea did you serve Tang Huai'an?"

"Yes...... It's Ulan tea...... It was the tea that the lord gave to the little prince, and the lord said that this was a flower tea from the Western Regions, with a unique taste, and he specially asked me to bring some ...... to the little prince."

"I just asked you what kind of tea you served, and you explained so much to me...... What are you doing with a weak heart......

Lingyue's body stiffened, and her voice was unnatural.

"Big ...... My lord, the slave just thought that the adult would have to ask these questions next, and she didn't have a weak heart......

The eldest grandson's eyes narrowed, releasing a danger signal.

"Then how did you know that dipterocarp and orchid together would make a warrior instantly incapacitated?"

"My lord, I don't know what you mean."

The eldest grandson picked up the red-hot soldering iron, and in the dark interrogation room, the red light illuminated the eldest grandson's face flickering.

"Then I'll help you remember it......

"Someone, torture!"

After the eldest grandson finished speaking, the iron door of the interrogation room opened, and several patrols came in and directly hung up Lingyue and began to execute.

"My lord, I don't know anything......

The eldest grandson was expressionless, without a trace of emotion in his eyes, turned around and walked out of the interrogation room, and Lingyue's howl of pain came from inside the iron door.

Yun Xuezhi looked at the eldest grandson who came out, frowned, and expressed some dissatisfaction with his torture.

"Wangcai, are you planning to bend into a trick?"

There was also Zhou Mi on the side, but he had long been accustomed to such scenes, without any expression.

The eldest grandson looked at Yun Xuezhi with a smile, "It's good to be able to bend into a move, and the emperor will have an explanation."

"Nonsense! Am I the kind of man who wronged innocent people!"

"Then do you feel that Lingyue is innocent?"

"Rei Yue ......".

Yun Xuezhi just wanted to refute the eldest grandson, but found that the clues they had found in the past two days all pointed to Lingyue.

"No matter what, you can't bend to it...... Didn't you say that you pay attention to evidence in everything!"

The eldest grandson looked at Yun Xuezhi with a smile, feeling that he had changed in the past two days.

In the last dream, the eldest grandson looked at Yun Xuezhi's analysis of the case and could clearly feel that he had a sharp mind, but he believed in intuition too much and lacked evidence for the reasoning of the case.

The eldest grandson smiled, not planning to continue to make fun of Yun Xuezhi.

But before the eldest grandson could speak, Zhou Mi first said, "Wangcai, you have a deep meaning in this move, right? I saw that the patrols were all measured, and they didn't use any big punishments, looking at the tragic scene, in fact, it just made Lingyue suffer some flesh and skin."

is worthy of a veteran, and you can see it at a glance.

The eldest grandson secretly appreciated it in his heart, and then said, "The patrol who has been staring at Lingyue for the past two days told me that after we finished the interrogation in the Huaiwang Mansion, Lingyue met Tang Huaide."

Zhou Mi nodded, this matter was reported to him.

"Do you suspect that Tang Huaide and Lingyue are colluding?"

"That's pretty much for sure, it's easy to get Reiyue to confess. Through the interrogation, it can be seen that she is just a simple maid, and the reason why she still refuses to let go should be Tang Huaide's instructions."

"So what are you going to do, really

Let Lingyue bend into a trick?" Zhou Mi asked.

The eldest grandson shook his head, "If that's the case, Tang Huaide will inevitably put all the blame on Lingyue, this is not the result I want."

"Okay, let's all go back, and summon Tang Huaide for interrogation tomorrow." The eldest grandson said.

Before Zhou Mi left, he looked at Lingyue, who was still being tortured, with some hesitation, "Wouldn't it be inappropriate to torture the people of Huaiwangfu like this?"

"It's okay, now King Huai doesn't dare to provoke us again, after all, we have this in our hands." The eldest grandson raised the spirit weapon of the remnant clan in his hand, and then as if he remembered something, he turned around and continued to say to Yun Xuezhi.

"By the way, you still have to show the Holy Saint about the relics spirit weapon, as for what to say, just say it as you thought before."

Yun Xuezhi was stunned for a moment, what did he think before, and how did he know?

After returning to Bailian Chenggang, the eldest grandson and Wu Dakui discussed the progress of the transformation of the dragon chariot.

Although the transformation of Longyan is Liu Xinyan's errand, it seems that it has nothing to do with Tang Huai'an's case, but the eldest grandson always has a hunch that the transformation of Longyan is equally important.

Now that the transformation of Longlin is basically completed, Wu Dakui used the shock absorber designed by Changsun on the frame of Longran, and at the same time, Yun Xuezhi also added the flying carpet of the first dream to the carriage.

The combination of the two produces even better results than the suspension array.

This also makes Wu Dakui full of energy, this is an innovation that surpasses the old things, and the most important thing is that the shock absorber is much lower than the suspension array, both in terms of cost and difficulty.

After learning about the progress of the shock absorber, the eldest grandson returned to the room and thought about the progress of Tang Huai'an's case again, and now the eldest grandson has a basic conjecture about the process of the case.

First of all, through the interrogation of the subordinates in the Huaiwang Mansion yesterday, the eldest grandson came to a conclusion that Tang Huaian was interested in Lingyue, and Lingyue had a personal relationship with Tang Huaide.

So the eldest grandson guessed that Tang Huaide should have taken advantage of this and instructed Lingyue to poison Tang Huai'an, and then commit murder.

As for who killed Tang Huai'an in the end, this is also one of the purposes of the eldest grandson's torture of Lingyue.

If Lingyue was just a weak woman who was powerless, then she couldn't kill Tang Huai'an from the back of her head with a hosta.

With torture, you can see from the side whether Lingyue is a weak woman.

At the same time, the eldest grandson tortured Lingyue in order to scare Tang Huaide.

At this time, Tang Huaide and Lingyue were angry, and they thought that they were already mentally prepared, and they would definitely gain nothing by interrogating him directly, so what the eldest grandson had to do now was to break through Tang Huaide's psychological defense, and using torture on Lingyue was the first step.

After going through the case, the eldest grandson still has one of the biggest doubts, where did this relict spirit weapon come from?

The eldest grandson still can't figure out why this spiritual artifact appeared at the scene of the crime.

Yun Xuezhi didn't know yet, but the eldest grandson knew that this spiritual artifact was not just a simple relict spiritual weapon, but also a spiritual object space that specially sealed spiritual objects.

Such a spiritual weapon can even be called precious, how could it appear at the scene of the crime for no reason?

At this time, the eldest grandson thought of the "bureau" mentioned by Yun Xuezhi in the last dream......

The eldest grandson, who couldn't figure it out, decided to put this doubt aside for a while, thought about it again for a while, remembered that there was still a little missing, and got up and went to another room.

It was Chen Tian who was locked up in the room, and after the eldest grandson went in, he told Chen Tian about Tang Huaide going to Dali Temple to report the case.

Sure enough, this news directly aroused Chen Tian's brainstorm.

When Chen Tianru had a dream, he repeatedly thought about why Tang Huaide went to Dali Temple to report the case because of some property, and he was directly involved in Tang Huai'an's murder.

Chen Tian only now understood what the eldest grandson meant when he caught him before, "keep you from dying", and it turned out that this was exactly what he was referring to.

Now the key to whether he can survive has become whether Tang Huai'an's case can be successfully solved, and the eldest grandson is directly involved in the case, isn't he in control of his own life and death.

Chen Tian looked at the eldest grandson with a cold sweat on his forehead, and the eldest grandson was like a god in his eyes at this time.

From being caught by the eldest grandson inexplicably, everything that has happened to the present seems to be in the hands of the eldest grandson.

"Figured it out?" The eldest grandson looked at Chen Tian with a smile, but Chen Tian was so frightened that he trembled.

Then the eldest grandson let Chen Tian out and arranged for him to go to Tang Huaide's courtyard again.

Jiu'er will go to Tang Huaide's courtyard tonight, and the conversation between the two after that is of course clear to the eldest grandson.

The reason why the eldest grandson would arrange for Chen Tian to go was actually to not let Zhou Mi and Yun Xuezhi doubt him.

The next day, the eldest grandson returned to the interrogation room of Dali Temple, and first glanced at Lingyue, at this time the weak girl was curled up in the corner, and the blood oozing from her clothes proved that she had endured a light punishment yesterday.

At this moment, the eldest grandson turned into a demon in Lingyue's heart.

The eldest grandson's face was expressionless, and when he saw Lingyue's state, he knew that yesterday's patrol was just right with punishment.

In the interrogation room, the eldest grandson sat on a chair like this and did not interrogate.

This deathly silence tormented Reitsuki, and just as she was about to take the pressure and was about to let go, the iron door of the interrogation room opened again.

It was Tang Huaide who walked into the interrogation room.

Tang Huaide's face was cloudy, why was he summoned by Dali Temple? And now I'm in the interrogation room!

The eldest grandson faced a royal clansman, his face remained unchanged, still cold, as if he did not have a trace of emotion.

Tang Huaide, who was already in shock, couldn't help but chuckle in his heart when he saw Lingyue, who had a miserable image in the corner.

When Lingyue saw Tang Huaide, as if she had seen a savior, she struggled to stand up and pounce, but the next second Tang Huaide turned her head decisively.

It was as if he wanted to dissociate himself from himself.

At this time, Lingyue remembered Tang Huaide's previous instructions, so she curled up back under the gaze of her eldest grandson.

Tang Huaide regained a trace of composure, looked at the unattractive man in front of him, and said in a cold voice, "This is to interrogate this son as a prisoner?"

Since the eldest grandson also kept Lingyue, he didn't want to deceive Tang Huaide as soon as he came up.

"Tang Huaide, I suspect that you have something to do with Tang Huai'an's murder case, and now I have a few questions for you, please answer them truthfully!"

Tang Huaide was dismissive.

"Tang Huaide, where are you on the evening of September 10?"

"In the dormitory, of course."

"Can anyone testify?"

"Anyone can testify."

"I interrogated all the people of the palace, and they all said that they had not seen you since ten days."

"I drank some wine, and when I was tired, I went back to my room early to rest. Why not?"

The eldest grandson did not dwell on this issue, as long as Tang Huaide could not prove that he was not present at the time of the crime.

"Let me ask you again, Tang Huai'an was appreciated by King Huai for the errand of preparing for the autumn hunt, have you ever been jealous?"

"Nope."

"Then why did you instruct Lingyue to poison and murder Tang Huai'an?!"

When Tang Huaide heard this, his expression became even more disdainful, he thought that there would be any conclusive evidence, but now it seems that the other party is just guessing for no reason.

That doesn't scare him!

"Do you have proof?"

The eldest grandson did not answer.

Tang Huaide immediately got up and said aggressively: "You suspect a royal family member without any evidence, you are so bold!"

The eldest grandson's expression was like looking at a jumping clown.

"If you want proof, then let's talk about evidence......

"I found a special kind of petal in the teacup in the north study, this flower is called Ulanhua, can the prince know?"

As soon as the eldest grandson said this, Tang Huaide's momentum just now was swept away, and his face was cloudy again.

"Of course the prince knows, because this flower tea was given to King Huai, and then King Huai gave it to Tang Huai'an."

Tang Huaide pretended to be calm, "This flower tea is indeed dedicated to my father, I ...... I also got a little bit by chance, hair

Now the taste is unique, so I want to dedicate it to my father, what's wrong with that?"

The eldest grandson smiled and said, "Then why is there a black orchid flower garden in the courtyard of the prince in Shunfeng District?"

Tang Huaide began to panic a little, he knew very few people in the courtyard in Shunfeng District.

In order not to let people know, he didn't send guards from the palace, but just found a porter from outside.

The eldest grandson continued, "The prince likes the orchid so much, he doesn't know that the combination of the orchid flower and dipterocarp can instantly numb a sorcerer mirror martial artist, right?"

Tang Huaide immediately pretended to be stupid when he heard this, "What are you talking about? I just like the orchid, and I don't know anything about it."

The mouth is quite hard.

"A few days ago, I heard that the prince's house was stolen, but did you lose anything important?"

Tang Huaide said with a dry smile: "This matter has nothing to do with Tang Huai'an's case, so I won't bother with it."

My lord?

The eldest grandson sneered in his heart, this Tang Huaide had already begun to feel weak.

"Oh? I'm afraid the prince forgot, it was you who reported that the thief was a remnant, and it was related to Tang Huai'an's murderer!"

"Uh...... That's what I said......

"How do you know that Tang Huai'an's case is related to the bereaved family?!"

"It's because ......"

Tang Huaide suddenly stopped, knowing that he was about to say something, and at the same time realizing that his statement about reporting the case seemed to be exposed.

But how could the eldest grandson give him time to react?

"Don't dare to say it, then I'll help you say it, it's because of this, right!"

The eldest grandson threw the relics spirit weapon in front of Tang Huaide.

"This spiritual artifact was retrieved from the scene of the crime by my family Master Yun, and it was not until yesterday that I found out that it was a relict spiritual artifact, how did you know?!"

"I...... I don't know......

"Then how do you know that Tang Huai'an's case is related to the bereaved family!"

Tang Huaide was stunned in place, he finally knew where he had shown his feet.

But it was too late.
