Thousands of years of ice, the cold air attacked slowly, and a body like a living person appeared in everyone's eyes, revealing different looks.

"I'm tired of the three seniors, please help find out the cause of death. Yang Yi said slightly.

"Don't worry, there's no one in the world where we can't find out the cause of death. The poison demon said with a slight wave of his hand.

"Thank you!" Yang Yi bowed deeply, then stepped back, looking at the three of them quietly.

"Let's get started!" the poison demon commanded, and the three of them began to work at the same time.

The poison demon tapped lightly on the body a few times, and said in his mouth: "Well, the body is very well preserved, just like a real person, it must be highly poisonous." ”

"Senior, I don't know what kind of poison you have?" asked Yang Yi.

"This poison is rare in the world, it has not been discovered, and it will take some experiments to know. The poison demon frowned, took out the small bottle, and gently touched the wrist of the corpse, and a stream of bright red blood flowed into the bottle.

"There is not a trace of soul in the body, even if it is stored for two years, it is impossible to have such a phenomenon, it must be caused by the heavy damage to the soul!" "The soul demon's right hand was against the forehead of the corpse, glowing black, his brows were furrowed, and Nuno said.

"There was no damage to the body, and after verification, the soul was scattered and died. After some probing, the magic doctor took a few hairs and nails, and said thoughtfully.

"Three seniors, what is the result?" Yang Yi asked respectfully.

"It has not been found yet, but the poison of the body has been determined, but it will not be able to find out what poison the body is for a while, and it is necessary to explore the place where the deceased was alive to reach a certain conclusion. The poison demon said lightly.

"Sister Xiyan, please lead the way. Yang Yi gestured.

"Please come with the juniors!" Leng Xiyan saluted slightly, and walked outside the ice cellar.

"Three uncles, please be sure to find out the cause of death. Li Lingxuan said slightly.

Seeing this, the three poison demons hurriedly walked over, flattered and said, "Miss, you are serious, your subordinates will do their best, don't worry." ”

"Three seniors, please!" Yang Yi stretched out his hand and signaled.

Yang Yi and the others followed Leng Xiyan all the way to the place of long-term retreat in the first few years of her father's death. Fortunately, this place has been guarded for a long time, and the site is well maintained, even if someone came in to investigate before, it did not damage the scene.

"Don't come in, just leave it to us. "Just as they were about to enter the retreat, the poison demon opened his mouth to preach and stop everyone outside.

"Senior, can the three of us enter?" Yang Yi asked.

The poison demon hesitated for a moment, then replied, "You can come in, as for the others, forget it." ”

"Thank you, senior. Yang Yi's face was overjoyed, and he motioned for Wang Ye and Xiang Haoyu to come in, and at the moment when the retreat place was closed, he also deliberately left a sentence.

"Sister Xiyan, Senior Nephew Li Gan, I bother the two of you to stay here, don't let anyone here leave early. ”

"Little one, tell me what the purpose is. With a wave of his hand, an invisible barrier rose.

"Hehe, it's still the senior's sharp eyes, and you can see the younger generation's careful thinking at a glance. Yang Yi said with a smile.

"Hmph, hurry up, I don't have time to spend here with you. The poison demon said coldly.

"Senior, you've all seen the body, I don't know if you have found anything?" asked Yang Yi.

The poison demon frowned, a little impatient, and said, "Didn't you talk about it in the ice cellar? Why are you still asking here?" ”

Yang Yi just smiled slightly, and continued to ask, "I don't know if you suspect each other?"

"Oh, looks like you have someone in mind. The poison demon was slightly shocked, thinking that they already knew who had done it.

"Senior, the Demon Sect and the Ming Sect have been fighting for thousands of years, so you must know a lot about the Ming Sect. Yang Yi smiled inexplicably and looked at the three old men in front of him strangely.

"Mingjiao, are you doubting Mingjiao?" the soul demon suddenly exclaimed.

"Hmm!"

Yang Yi nodded and continued: "I don't know if the three seniors have heard that the emperors of the other three empires also died suddenly a few years ago, and no cause of death has been found so far. ”

The poison demon, the demon doctor, and the soul demon glanced at each other, and said with a solemn face: "The three of us are all recluses, and it's really the first time I've heard of it. ”

"Three seniors, think about it, if you can poison the emperors of the four empires at the same time in almost the same period of time, and make people unable to find any flaws, who else under heaven and earth, or what kind of force can do it. Yang Yi said solemnly.

"If that's the case, I'm afraid only super strength can do it. The three Poison Demon nodded.

"At present, there are only Holy Land, Demon Sect, Ming Sect, Killing Hall, Sword Valley, Sword Pavilion, and Ten Thousand Treasure Pavilion with such strength. But among these super forces, only Mingjiao and Killing Tang have the intention of hegemony, and among them, Mingjiao is even more blatant action. ”

"If it's expected, it should be Mingjiao. Therefore, if we want to investigate such a strange cause of death, we still need a fake person or force to do it, and after we have a goal, we may be able to find a clue. ”

"If we don't have a goal, we may only fall deeper into a fog, and even if we can find a clue, we can't determine, let alone determine the cause of death. ”

Yang Yi's words made the three poison demons very recognized, and inadvertently pointed out the direction for them, so that they had an object of suspicion in their hearts, so that they could prescribe the right medicine.

Yang Yi saw that the three of them were in deep thought, waited for a while, and asked, "Three seniors, judging from the remains, the deceased died of a strange poison. I don't know if you have the impression in your mind, whether there is such a poison in the Ming Sect that can severely damage the soul of the Emperor Realm powerhouse, or even scatter the soul. ”

The poison demon shook his head lightly and said: "Although there is a peerless poison in the world that can poison the Emperor Realm, and even the Venerable Realm, the signs of poison can still be found, and as for the strange poison that can be so unaware and nowhere to be found, it is really the first time I have seen it." ”

"Yes, this kind of strange poison has never appeared in the mainland. The magic doctor sighed.

"Three seniors, presumably there should also be masters of using and making poison in the Ming Sect!" At this time, Yang Yi suddenly woke up.

"Hey, there are many capable people in the Ming Sect, and even our Demon Sect is ashamed of itself. The poison demon sighed.

"I don't know if this strange poison was recently researched by Mingjiao. Yang Yi was slightly relieved to see that the three of them had entered his rhythm, because he was afraid that the three of them would be too cold and unwilling to communicate, and miss the clue to find the real cause of death.

"Since its inception, the Ming Sect has been researching strange poisons that can kill people invisibly, and perhaps this is their recent achievement. The magic doctor said lightly.

"Magic doctor, do you remember that more than ten years ago, the news came back from the inside, we didn't care at that time, and laughed it off, thinking that it was impossible to achieve it at all. The poison demon suddenly thought of a clue and asked.

"Old poison, I remembered what you said. At that time, the inside line mentioned that Mingjiao had recently been researching a strange poison, which was said to be able to kill the Venerable Realm in an invisible poison. At this time, the magic doctor also remembered the nonsense from before.

"But isn't the news from the inside already a failure? The Magic Doctor exclaimed.

"Yes, it is precisely because of the failure that we laugh at the fact that Mingjiao is impossible to achieve. The poison demon sighed.

Suddenly, the magic doctor exclaimed, "Did they succeed!"

"It shouldn't be possible, if it was really successful, the Ming Sect would have already made a big move, and it would have to wait until now, and it would have been necessary to test the four empires first. What's more, if the Ming Sect really succeeded, how could he use such an important strange poison on the Emperor Realm, isn't this a tyrannical celestial thing. The poison demon said categorically.

"Poison Demon Senior, do you think this is a half-finished product, although it can't poison the Venerable Realm, but it can poison the Emperor Realm. At this time, Yang Yi suddenly mentioned the key.

When the three of them, the poison demon, the demon doctor, and the soul demon heard this, and exclaimed at the same time: "Soul incense!"

"Soul incense, what is it?" Yang Yi was surprised, Wang Ye and Xiang Haoyu also looked at the three of them at this time, as if they were not far from the truth.

"Soul incense is a strange poison newly researched by the Ming Sect, and its medicinal effect can only work on the King Realm, the Emperor Realm, and the Emperor Realm. As long as the person who is infected with this poison has ingested a sufficient amount of poisonous gas, his soul will be slowly corroded, and he will not notice any symptoms at all except on the day of the poison. And on the day of the poison, the soul of the person who is planted with this poison will suddenly collapse, and eventually the soul will scatter and die, without even the slightest chance of treatment. Poison Nono said.

When Yang Yi heard this, his face was overjoyed, and he knew that the truth had come out. However, in order to confirm it, Yang Yi still opened his mouth to ask and conclude with this.

"Senior, I don't know if the person who is poisoned by this poison will not have any poisoning. ”

The poison demon nodded and replied, "Well, that's right. Not surprisingly, the four emperors died of this poison. ”

"Senior, I don't know how this soul incense is poisoned?" Yang Yi asked.

"If you want to poison it, you need to set it on fire in the place where the poisoned person stays for a long time. Since the poison is colorless and odorless, it will not be detected as long as it is ignited. The poison demon replied.

"Looks like we're going to have to look for something here. As soon as Yang Yi's words fell, he began to look for them.

Seeing this, the poison demon smiled slightly and said, "Don't be so troublesome, look at the old one." ”

I saw that the poison demon took out a drop of the blood from the corpse before, and with a slight click, the blood suddenly disappeared, turning into a colorless and invisible light mist, gradually floating the entire retreat place.

Suddenly, a faint mist burst into flames when it came into contact with the two lamps and candles.

"Found it, these are these two places!" the poison demon's eyes shot a green glow, and suddenly appeared in front of the two lamps and candles.

"Could it be that these two clumps of white powder are dementor incense?" Yang Yi took a closer look, only to see that there was a ball of white powder on the lamp and candle, while the other lamps and candles did not have this ball of powder.

"This is the powder of the dementor incense after it has been burned. The poison demon poked a little bit with his little finger and tasted it.
