Yang Qingyuan was not used to people kneeling down to him, even though Tang Lian had a very bad attitude towards him before.

With a flick of his hand, the real energy lifted up Tang Lian.

With this move, Yang Qingyuan used it from the Cave Mysterious Realm to the Fa Tian Xiang Earth Realm.

"I used to be the minister of Dali Temple in the imperial court, and now I am the deposed envoy of Yizhou. The death of Tang Chi involves such a case, and we will definitely investigate it to the end."

"By the way, please remember, Hall Master Tang Lian, where you touched the room and what you moved. Don't miss it."

"I was so concerned about my brother that I didn't notice anything else. It was probably my brother's body that I touched, nothing else."

About half an hour later, Yang Qingyuan finished questioning Tang Lian. He also questioned other important figures in the Tang Sect, as well as some ordinary disciples.

Among the Tang sect, the one who had the deepest hatred against Tang Chi was Tang Wei, the son of Tang sect leader Tang Zhang.

Qianji Hall and Ghost Ax Hall have always been the core departments of the Tang Sect.

Qianji Hall is responsible for the research and development and improvement of hidden weapons, while Guixue Hall is responsible for the production and production of hidden weapons.

The heads of the Tang Sect in the past have always chosen their successors from the Qianji Hall and the Ghost Ax Hall.

Although the Tang Sect is a family-based sect, the position of Tang Sect leader has never been passed down from father to son.

According to the Tang Sect's rules, within the three realms, those who are capable will take the place.

This is the only way to ensure that the Tang Sect can survive to this day.

The next head of the Tang Sect will be between Tang Chi and Tang Wei.

Although Tang Wei is the son of Tang Zhang, the sect leader, in terms of prestige in the Tang sect, Tang Chi is still three points higher.

Although Tang Chi was obsessed with the study of hidden weapons, he was fair in dealing with things and won the hearts of the people in the sect, and was respected by most of the Tang sect disciples.

Now that Tang Chi is dead, from the current point of view, the one who has benefited the most is Tang Wei.

The biggest obstacle to his succession as the head of the Tang Sect has been eliminated. Even if a new leader of the Thousand Machines Hall is elected, there is no way to compete with Tang Wei.

On the surface, this is correct, but if one follows this line of reasoning, then Tang Wei's timing to take action is extremely poor.

When can you not kill Tang Chi?! You have to do it when Yang Qingyuan is investigating the Tang Sect?!

Even if you want to frame the blame, there is no such way.

After recording the confession, Yang Qingyuan ordered people to bring in all the collected evidence.

There's not much else. The murderer did it cleanly and no key evidence has been found so far.

Only the drawings laid out by Tang Chi on the table and the rainstorm pear blossom needle brought by Yang Qingyuan are intriguing.

Looking at the scattered drawings on the table, it seems that Tang Chi had been studying the Heavy Rain Pear Blossom Needle before his death.

The Rainstorm Pear Blossom Needle brought by Yang Qingyuan had been disassembled into less than half, but was destroyed.

A silver needle penetrated the mechanism of the Heavy Rain Pear Blossom Needle, causing its self-destruction system to activate. Although nothing could be seen on the surface, its interior had already turned into a ball of scrap metal.

"So the purpose is to destroy this Rainstorm Pear Blossom Needle?"

Yang Qingyuan looked at the Rainstorm Pear Blossom Needle in his hand and fell into thinking.

The murderer's criminal purpose will be the key to determining the direction of the investigation.

If Tang Chi was killed in order to destroy the Rainstorm Pear Blossom Needle and cover up the secret, it must be related to the assassination of Thirteen. It involved more than just one Tang sect, and it might have been done by an outsider.

But if the purpose was just to kill Tang Chi, then it was probably someone inside the Tang Sect who did it, and the act of destroying the Heavy Rain Pear Blossom Needle was just to confuse the public.

Just as Yang Qingyuan was sorting out the case again and again, the detective responsible for questioning came back.

"Yang Hou, all the people who need to be questioned have been asked and the notes have been completed."

"Well, thank you for your hard work." Yang Qingyuan also stood up.

They have to go back to the six doors to further investigate and collect evidence.

Yang Qingyuan and his party came to the door, "Master Tang, could you please ask more at the door to see if you find anything unusual or anyone suspicious?"

Tang Zhang agreed repeatedly to Yang Qingyuan's words.

"Master Yang, walk slowly..."

Although Tang Zhang was very considerate and polite to Yang Qingyuan, Yang Qingyuan didn't know why he just looked at the old man unhappy. He always felt that he was a poisonous snake lurking in the shadows. When you were napping, he would suddenly attack and bite you.

Tang Zhang breathed a sigh of relief when he saw Yang Qingyuan and his group walking away.

This plague god is too troublesome.

----------------------------

After returning to Yuzhou Liumen, Yang Qingyuan saw Li Changyuan smoking a dry cigarette leisurely.

Li Changyuan is capable, and his ability can easily serve as the chief catcher of the Liumen Branch in Yuzhou. Therefore, Li Changyuan can fish and make trouble without affecting his official duties.

The leader works, you fish!!

Is there any more royal method?!

"Captain Li, have you found any clues about the body?!" Yang Qingyuan asked.

"Yang Hou, we have found out that in Niutou Village in the mountains outside Yuzhou City, a woodcutter was lost. His height was about the same as the estimated height of the deceased. When he was collecting firewood on the mountain, he accidentally fell and broke his body. He is probably

He got lost half a month ago. He has reported it to the authorities, but there has been no news."

Height and features are consistent.

It's probably this person! It's a pity that current technology cannot identify the genetic skeleton and confirm his identity.

The two cases come together, both related to the Tang Sect. They seem to be related, but in fact they are completely unrelated.

"Is Wu Zuo back?"

"is back!"

"Let him prepare for the autopsy!"

"Yes, Yang Hou!"

One of the reasons why Yang Qingyuan brought Tang Chi's body back was for an autopsy, and he had obtained permission from his family.

Yang Qingyuan had a hunch that finding out the cause of Tang Chi's death would be a key step in this case.

Half an hour later, Wu Zuo pushed open the door and went out to report to Yang Qingyuan.

"How?! Have you found out the cause of death?"

Wuzuo shook his head in embarrassment, "Please forgive Yang Hou for his incompetence. Is it true that he cannot find out the cause of the deceased's death?"

"Isn't it poisoned?!"

Facing Yang Qingyuan's question, Wu Zuo was a little unable to answer.

"Because it has been too long, the five villages and six internal organs have begun to deteriorate. However, my subordinates have not detected any poison from Tang Chi's body... I really dare not make a conclusion!"

"..."

It would be outrageous to not be able to detect poison.

There are many poison techniques in the world, and there are many types of colorless and odorless poisons that can poison people without being detected.

But which poison can eliminate all traces after death!?

It is colorless, odorless, and difficult to detect. The key is to make the target defenseless before being poisoned. Once the target is poisoned, these characteristics will almost lose their effect.

More importantly, the passing geese leave a sound, and the passing wind leaves a mark. How could poisoning a person leave no trace at all?

Not only was it the work of the six gates, but the people in the Tang gate didn't see any clues either.

"The deceased didn't have any internal injuries, right?" Yang Qingyuan had just checked, but now he was a little unsure because of this man's manipulation.

"This subordinate can confirm that the deceased had no internal injuries. It looks more like... he died suddenly after vomiting blood."

So the Tang Sect’s Qianji Hall Master, a Yuan Hua realm warrior, died suddenly of vomiting blood because of staying up late for a long time?!

This seems very reasonable...it's so reasonable!

This is a Yuan Hua realm warrior, not an everyday programmer!

Sudden death is mostly caused by coronary heart disease, acute myocardial infarction, coronary atherosclerosis, but for Yuan Hua realm warriors, all eight meridians are connected, and the true energy feeds back into the physical body.

How could he die suddenly?!

"Okay, thank you for your hard work! Go down and rest!"

"yes!"

After Yang Qingyuan thought for a moment, he called Li Changyuan.

"Captain Li, please summon the capital of Shen immediately and ask them to investigate two things!"

"First, collect the files related to the Tang Sect and send them over immediately."

"Second, search the world for strange poisons to see if there are any strange poisons that will disappear on their own after death."

Li Changyuan replied, "Don't worry, Marquis Yang, my subordinates will take care of it immediately."
