The eldest grandson and Zhou Mi returned to Bailian into steel, and after discussing with the two, it was decided to temporarily lock Chen Tianye in the blacksmith shop and hand it over to the eldest grandson to take care of.

Wu Dakui was still busy in front of the refining furnace, the spiritual weapon given by Yun Xuezhi and the transformation of the dragon chariot made him have no time to rest in the past two days, and the eldest grandson and his party returned to Wu Dakui and didn't even have the energy to look up.

After the eldest grandson placed Chen Tian properly, he took out the hosta and looked at it.

Zhou Mi didn't leave, he had too many questions to ask the eldest grandson, but at this time he didn't know where to start.

The eldest grandson looked at it for a while, put the hosta away, and looked up to see that Zhou Mi had not left yet, and was a little surprised.

"Lord Zhou, are you staying overnight in the Humble House tonight?"

Zhou Mi shook his head, stopped talking, and finally asked.

"You...... Was there a major discovery today?"

The reason why Zhou Mi was a little hesitant was because he was the head of Dali Temple, and in Tang Huai'an's case, Dali Temple did not make much contribution, especially after Yun Xuezhi took over the case.

Today, Zhou Mi paid attention to what the eldest grandson did, and he always had a feeling that this person was not simple.

Most importantly, he saw a kind of concentration in his eldest grandson, which was the same as when he first entered Dali Temple.

However, after so many years of ups and downs in officialdom, it seems that the momentum of that year is about to be exhausted by time.

The eldest grandson was a little hesitant, not because he didn't trust Zhou Mi, but because the conjecture in his heart still needed to be confirmed at the scene of the crime tomorrow, and he didn't want his conjecture to mislead Zhou Mi now.

But the eldest grandson's hesitation made Zhou Mi mistakenly think that the eldest grandson didn't want to be open and honest.

This is also normal, the current Dali Temple is not said to be on the opposite side of Yun Xuezhi and the eldest grandson, but it is definitely not a reliable partner.

Zhou Mi hurriedly said that he was abrupt, and he was ready to leave.

"Lord Zhou, slow down, there are indeed some gains today, but all this is still in the stage of conjecture, and after we go to the scene of the crime together tomorrow to confirm, we will definitely talk to Lord Zhou in detail."

Zhou Mi nodded, and the two said goodbye after agreeing on a time.

The next day, the eldest grandson and others came to Yun Xuezhi and took Chen Tian to the Huaiwang Mansion together.

Zhou Mi was already waiting in front of the house, and everyone entered the house after passing through the ceremony.

Chen Tian was like a frightened fledgling at this time, a thief like him had never even been to the inner chamber, let alone entered the palace at this time!

Chen Tian was a little cringe, and then looked at the eldest grandson who was walking in front of him calmly, he knew that he had really encountered a hard stubble this time, and at the same time thought in his heart that he would fully cooperate with the eldest grandson no matter what he asked.

Everyone came to the scene of the crime again, and the eldest grandson first reconfirmed it in front of the self-portrait of Tang Huai'an.

Then he handed the hosta to Zhou Mi, and regardless of Zhou Mi's shocked eyes, he walked directly to the incense burner and opened it and smelled it, and his eyes lit up.

"Sure enough, it's dipterocarp!"

Yesterday, when he looked at Tang Huai'an's portrait, he smelled a faint fragrance, but because the fragrance was too light, the eldest grandson didn't think of dipteroscope.

It wasn't until last night when Chen Tian mentioned the orchid and dipterocarp that he remembered this clue that he had ignored.

After confirming that the last burn in the incense burner was dipterocarp, the eldest grandson began to look for traces of the orchid in the study.

This is the eldest grandson guessing that Tang Huai'an's real cause of death!

The first time the eldest grandson saw the scene of the crime, he felt that Yun Xuezhi and Dali Temple had fallen into a misunderstanding: because Tang Huai'an was a sorcerer and a mirror martial artist, it was logical to think that the murderer was also a martial artist.

This kind of thinking is normal in the Kyushu Continent, after all, this is a world where warriors are respected, ordinary people are not as fragile as ants in front of warriors, but it is not much worse, how to talk about assassinating warriors?

However, the eldest grandson who crossed over did not have this kind of stereotyped thinking, which made him pay more attention to clues.

So when the eldest grandson saw the bloodstains on the desk, he concluded that Tang Huai'an was dead before his throat was cut!

If you're already dead, why do you have to cut your throat?

The eldest grandson's first thought was that the murderer wanted to cover up the real cause of Tang Huai'an's death and mislead the people who judged the case.

Of course, this is just the reasoning of the eldest grandson when he saw the scene yesterday, there is no evidence, these are all the assumptions of the eldest grandson, and it is exactly the case, so the eldest grandson did not rush to tell Zhou Mi last night.

Now dipterocarp has discovered that if the orchid can be found, the progress of the case will be reversed dramatically.

"No, there should be......

The eldest grandson looked at the bonsai in the study and found no trace of the orchid.

"Could it be that it was planted in the room before, and finally destroyed by the murderer?"

The eldest grandson checked the bonsai in the study again, and this time even picked up the flowers and plants in the bonsai to observe the flower soil.

However, the eldest grandson was disappointed again, and there was no trace of man-made destruction in all the bonsai flowers.

In this way, the conjecture that the eldest grandson suspected that the murderer pulled out the orchid flower was also overturned.

Everyone looked at the eldest grandson's strange behavior and muttering, and they didn't quite understand what the eldest grandson was doing.

"Wangcai, what did you find?" Yun Xuezhi asked.

Only then did the eldest grandson tell everyone about his conjectures and discoveries.

Everyone was shocked.

Zhou Mi was the first to come back to his senses and ran to the incense burner to confirm.

Chen Tian couldn't imagine that his unintentional words yesterday would be involved in a murder case, so that he still hasn't come back to his senses.

"Lord Zhou, has anyone been to the scene of the crime since the incident...... I mean, could it be that the murderer came and moved the orchid again? Or is it a cover for the presence of the orchid?" The eldest grandson asked.

Zhou Mi said with certainty: "In addition to Dali Temple, we are the only ones who have been to the crime scene, and there are patrols and guards around the study day and night, and it is impossible for the murderer to return to the crime scene......

Chen Tian came back to his senses at this time and asked, "Your Excellency...... Do you suspect that there were once orchids planted in this study?"

The eldest grandson nodded.

"No way, the root system of the orchid is very developed, don't look at this small flower, but the root system is often very deep, otherwise they will not be able to live." Chen Tian said firmly.

"In other words, the orchid is not suitable for growing in pots?"

"It would be more accurate to say that they don't survive in pots, so the orchids in that yard are planted in the flower beds."

The eldest grandson suddenly realized....

"And there's a very important point......

Chen Tian talked about what he was good at, and he regained some composure.

"If it's just one black orchid, or even a few, the floral fragrance produced is simply not enough to incapacitate a warrior. That's why there are so many orchids in that yard, otherwise it wouldn't have worked at all......

As soon as Chen Tian said this, the eldest grandson's brows furrowed even tighter.

If, as Chen Tian said, then the conjecture of the eldest grandson could not be established at all.

Who will plant orchids in a large area in the study? Even if it is planted in the mansion, it is not very likely.

The reason why Tang Huaide dared to plant orchids in his private courtyard was because that courtyard was located in Shunfeng District.

Most of the people living in Shunfeng District are civilians, and there will be no one there who can afford dipterocarp.

But the inner service area is different, dipterocarp is the favorite of dignitaries, and it is not a rare thing.

Therefore, if the black orchid was planted in a large area in the inner service area, it must have been exposed long ago.

"Am I wrong?"

Just as the eldest grandson fell into self-doubt, Chen Tian suddenly muttered.

"Only such a wealthy aristocrat can grow orchids like this, if I am willing to use them like this......

It was Chen Tian's unintentional complaint, but it instantly woke up the eldest grandson.

The eldest grandson turned his head and grabbed Chen Tian, staring at him with burning eyes.

"And how do you all use it?!"

"I...... We usually grind the orchid into powder and burn it into smoke, but the best effect is actually to eat the orchid......

Before Chen Tian finished speaking, the eldest grandson had already rushed to the desk.

The eldest grandson is flipping over

Carefully pinched a dried petal from the side of the teacup.

Chen Tian came to look at it, then sniffed it again, and said firmly, "That's right, it's the Ulan."

The other three looked at each other, and they all saw the shock in each other's eyes.

The eldest grandson's conjecture was correct.

So who is the murderer?

Yun Xuezhi and Zhou Mi are both smart people, and it only took a moment to think of it, and the two of them looked at the painting facing the desk and the hosta in the eldest grandson's hand at the same time.

"The hosta was found in Tang Huaide's courtyard?" Yun Xuezhi asked.

Zhou Mi nodded, he had already sent someone to verify that the owner of that annex was Tang Huaide.

"Then Tang Huaide is very likely to ...... He is the eldest son of the Huai Wangfu and the heir to the title, but Tang Huai'an has become the biggest threat to his succession to the title after he rose to power......" Yun Xuezhi then reasoned.

Zhou Mi nodded in agreement.

"The motive for the murder is established, and Tang Huaide is currently the most suspected, but evidence is still needed."

"What evidence?"

"Autopsy!"

After the eldest grandson finished speaking, the three of them fell silent in unison, and the case seemed to be back to square one.

But this time is different, and the determination to win can be seen from the eyes of Zhou Mi and Yun Xuezhi.

"This is not busy first, we must have enough reasons to persuade King Huai and Dali Temple to allow the autopsy, recklessly going to the two forces to negotiate the autopsy will only make us fall into the quagmire of the two sides, what we lack most now is time and energy."

Zhou Mi and Yun Xuezhi nodded.

The eldest grandson secretly thought in his heart, estimating that one more day the "reason" that would be enough to persuade the two forces would appear.

"So what do we do next?" Yun Xuezhi asked.

Zhou Mi and Yun Xuezhi looked at the eldest grandson at the same time, neither of them realizing that the eldest grandson had become their backbone.

"Call those people up again for trial."

Since he was already in the Huai Wang's Mansion, the eldest grandson simply interrogated those witnesses directly in the north study.

However, the process of the eldest grandson's interrogation made Zhou Mi and the two feel a little different.

The first is the object of interrogation.

When Zhou Mi and the two were interrogated, they both chose to interrogate the first witness, that is, the maid named Lingyue.

However, the eldest grandson put Lingyue in the final interrogation.

The second is the content of the interrogation.

Most of the previous interrogations of the two centered on the time when Tang Huai'an was found dead.

And the interrogation of the eldest grandson is more often about talking about Tang Huai'an's daily life with his subordinates. The chatter is miscellaneous, and even includes some gossip rumors about the Huai Wangfu.

This made the two people who were listening on the side a little confused.

It's time to interrogate Lingyue.

The eldest grandson looked at Lingyue, who had a good face and a slender figure in front of him, and just looking at her appearance and figure, people thought that it was the eldest lady of whose family.

What's even more commendable is that her nervous appearance of standing with her head bowed and her hands crossed makes people unconsciously want to be loved.

"Miss Lingyue, there are a few questions I want to ask you below, don't be nervous, just answer truthfully." The eldest grandson said softly.

Lingyue didn't dare to look up at the eldest grandson, and replied a little timidly, "The adults just ask, and the slaves don't dare to hide it......

"You are the maid of Tang Huaide's son, why did you appear in the north study on September 11?"

"My lord misunderstood, I'm not the servant of the prince. The slave maid usually serves the master in the north study, and the north study is used by the master again...... The prince also came often, so the slave and the maid also served the son......

The eldest grandson suddenly realized, and then said, "Later, King Huai gave the north study to Tang Huai'an's little prince...... That's why you're in the North Study that day?"

Lingyue nodded, still not daring to look up at her eldest grandson.

"In other words, the little prince was waiting in the north study on the night of the accident?"

Lingyue hesitated imperceptibly for a moment, then nodded in acknowledgement.

"Did anyone else enter the North Study that night?"

"The slave and maid did not keep a night here......

"Did anyone in the house go into the north study to serve?"

"As far as the slave knows...... Nope."

"In other words, Tang Huai'an's food and tea were all served by you that night?"

Lingyue nodded after obvious hesitation this time.

Just when Lingyue thought that the eldest grandson was going to continue to ask, the eldest grandson said softly, "Today's interrogation is here, there is Miss Lao."
