Half an hour had passed, and Fu Yi had already explained everything that could be told to Cang Lanqing, but the two still didn't find any clues in the main hall. There were no traces of Buddha's breath or attacks, and there were no items left, except for the scratches left on the beams and pillars and the top of the main hall.

Cang Lanqing also tried to fight with Fu Yi Xiao for two or three moves, and both of them only used one percent of their strength, and they still left indelible scars in the hall, which showed that that person did not use spells, swords and other offensive methods to kill the twenty-two Yuan Infants.

"Alas, it seems that there is no gain, otherwise I would have made up an anecdote and reported it, anyway, I can't produce actual evidence, and many monks are willing to buy these gossips!" Cang Lanqing looked very nerve-wracking, he said so, but obviously not very willingly.

Fu Yi came here to find a handle related to Hongmiao, so as to prepare for his hypocritical mask in the future.

She had already offended Hongmiao by rescuing the two elders of Zhou and Yuan, and most of the demon cultivators sent to chase and kill her in the follow-up were inseparable from him, so if she didn't fight back, she would be sorry for her reputation as "stopping demon cultivators from crying at night".

It's a pity that the most important council hall doesn't have any clues, and Fu Yi can't help but be a little disappointed, she can't even think of how a monk of the same realm can kill twenty-two monks quietly?

The slightest vigilance of a person will lead to a counterattack, and then there will be a vicious battle, but the twenty-two people of the Min family did not notice it from meeting the visitors until they died, did they all fall into some kind of illusion?

With a flash of inspiration in her mind, it didn't seem like a difficult task to put a group of monks who could trust her into a coma. If she had the heart to stun her classmates, she would not make a mistake at all.

"Cang Daoyou has any research on poisons?" Fu Yi came to the fragment of the tea bowl again, this time he didn't touch it with his divine sense, but carefully squatted down beside it.

Cang Lanqing reacted as soon as she heard it, and then squatted down and counted them one by one while observing the clothes.

"There are thousands of poisons in the world, but there are only three that can make the Yuanying Monk unaware of it. One of them, the crane tongue grass, no matter how it is refined, is red, and can only be used in a very dark liquid, and there is no red impregnation on this tea bowl, which can be ruled out. ”

"The second is the gallbladder, this thing is colorless but has a faint bitter taste, and it is even more obvious after purification, and can only be used in specific bitter spiritual food or elixir, and it is easy to be detected when injected with tea. ”

Cang Lanqing pointed to the faint traces of black tea foam on the fragments, and said in a firm tone: "This tea should be mixed with the leaves of the Cloud Tribulation Tea tree, this thing has no peculiar smell, and it can become a pure hallucinogenic poison with a little refining, and it will hardly leave a trace when mixed in the black tea, especially if it is taken out from the hands of a trusted person, it will not arouse any suspicion." ”

Cang Lanqing took out a jade slip and looked through it carefully, then put it in the storage bag, and then said: "The Cloud Tribulation Tea Tree grows in the land of demonic qi refinement, and it must not be contaminated with the breath of living beings, and it will not be affected until the fourth order. The fourth-order supergrade cloud robbery tea tree is not only hallucinating, but it can also make the dantian Zhongyuan infant fall into a state of suspended animation, and at that time, it can only be slaughtered by others. ”

"How can the cloud robbery tea tree be so poisonous?" Fu Yi was a little surprised, there was still one in her aura space, which was pulled from the ruins village, and she planned to bring it back to the grandfather and grandson who made tea.

She originally thought that this thing would be used to assist in refining spiritual tea and help people survive the heart demon tribulation, but she didn't expect that the difference between the different effects of refining methods was so big.

"The leaves of the Qiyun tea tree have no other use than being highly poisonous and hallucinating, and the friends of the Daoist still know that it has other uses?" Cang Lanqing was keenly aware of the familiarity with the tea tree in the words, and asked more in the instinct of collecting information.

Fu Yi thought that the family of the grandfather and grandson should not have established a clan yet, so he shook his head and laughed: "I heard that it was a tea tree, I thought it was brewed to drink......

Seeing that her expression did not seem to be fake, Cang Lanqing quickly put aside her doubts and did not ask any more.

"This kind of tea tree only grows in the Black Aya Mountains of the Thousand Silence Domain, and it belongs to the jurisdiction of the Silent Annihilation Sect, and it is not accessible to idle monks. The Qiyun tea tree was originally black, and it lost its medicinal properties after brewing, and it was impossible to judge by the black tea foam left in the fragments of the tea bowl, but I was eighty or ninety percent sure that the people who killed the Min family used this thing. ”

Fu Yi nodded in agreement, this matter is already clear in front of him, and there is nothing worth repeating.

Hongmiao, who has a cooperative relationship with Demon Cultivation, can easily get the fourth-order supergrade Cloud Tribulation Tea Tree, and Hongjin, who is close to Hongmiao, can easily take the black tea mixed with the tea tree and come to the Min family to let everyone drink a pot.

Whisk picked up the pieces of black tea foam on the ground, a total of nineteen pieces, and the rest were clean. "Do you want to take it away in a few pieces?" she always felt that as long as there were traces left, it was impossible to have no verification method at all, maybe everyone couldn't get the leaves of the Qiyun Tea Tree, and they couldn't distinguish it by incomparably meticulous comparison.

She happened to have a living Tribulation Cloud Tea Tree in her hand, and it was growing as long as possible in the aura space, and it was better to tear off a trace to compare the marks on the fragments than to judge it just by the records.

Cang Lanqing waved his hand and said no, he was used to judging according to the records of the family jade jian, since the jade jian said that the cloud tea tree was no different from the spirit tea foam after soaking in water, then there was no need for him to stay and take it away. "In fact, this speculation is enough to prove many things, what do you think?"

"Not bad. Fu Yi nodded, with a bit of guidance in his tone, "According to Cang Daoyou, can he succeed in stealing it in person with Hongjin's strength?" If it doesn't work, then he asks the Silent Annihilation Sect to rob the cloud tea tree, will the elders of the Silent Annihilation Sect give it?"

"It's rare hallucinogenic poison, it's still a fourth-order superproduct, and it's strange that the Silent Annihilation Sect doesn't pinch it to death. As far as I know, the entire Black Aya Mountain Range is under the control of the Silent Annihilation Sect, not to mention Buddhist cultivators, even non-sectarian demon cultivators may not be able to enter. ”

Although Cang Lanqing didn't say it directly, the meaning was already very clear, with the Silent Annihilation Sect guarding, it was almost impossible to steal such a rare poison.

"If someone asks for it, it needs to be friendly with the Silent Destruction Sect, or there is a great deal of interest involved. Although Hongjin has always followed Master Hongmiao, his status is not high, oh no, it should be said that it is nothing in the eyes of the Demon Cultivator and the Four Great Demon Sects. ”

Seeing that there was no dissatisfaction on Fuyi's face, Canglan Qing said with a bit of temptation: "If it were Master Hongmiao who spoke, the Silent Annihilation Sect would be able to give this some face." ”

Seeing that he finally stopped scruples about this and that, Fuyi went straight to the point, with a clear smile on his face. "I see. Does that fellow Daoist know what the relationship between the Silent Annihilation Sect and Master Hongmiao is?"
