Ye Qingtang suddenly spoke, making Zhou Xuan's face slightly stunned, and then sneered:

"Senior Sister Ye, there are more than 300 heads here, what kind of situation is it, it still needs to be carefully investigated, I don't blame you for being young and playful, but you shouldn't use these arbitrary words to prevaricate at will. It is related to the lives of more than 300 people in Juling Mountain Villa, and every corpse here needs to be carefully examined in order not to miss any clues. It's not something you can cover up with just a few sentences, you're really too child's play. ”

The other two disciples also showed obvious impatient expressions, they would not believe that Ye Qingtang could investigate the situation of these three hundred heads in such a short period of time, and also came to such a perfunctory conclusion.

Ye Qingtang smiled and looked at everyone's doubts, his white and tender fingertips wiped the pus from the carrion, pinched the chin of the head, and pinched out the erosive tongue.

"Senior Brother Zhou, can you see clearly that there is anything abnormal about this person's tongue?"

Zhou Xuan frowned slightly, looking at the erosive tongue that was almost not round, his heart was full of nausea, but he pretended to be calm and said, "It's just a rotten tongue." ”

Ye Qingtang chuckled, and with his other hand, he directly pulled out the dagger on his waist, scraped off the thin layer of mucus on his tongue, and stretched it out in front of Zhou Xuan's eyes.

Looking at the disgusting puddle of mucus that suddenly appeared in front of his eyes, Zhou Xuan almost didn't vomit it on the spot.

"Senior Brother Zhou, although this tongue is rotten and unformed, the crumbs of the Broken Source Grass hidden in this tongue coating are still well preserved."

"Broken Source Grass?" Zhou Xuan's complexion changed slightly, and then he resisted the urge to be disgusted and took a closer look at the mucus on the dagger.

Sure enough, in the midst of the filth, some dark green plant debris was faintly visible, but the debris was so small that if you looked closely, you would not notice it at all.

"Broken Source Grass is a poisonous weed that grows on the edge of cliffs, although this herb is not fatal, but it will make people faint in a very short time, and the five senses will be lost, no matter how big the movement around them is, they will not wake up.

And the broken source grass does not have any smell, if it is crushed and mixed into the tea, at most it will make people think that it is tea foam, and it will not be noticed. ”

Ye Qingtang said with a smile:

"On the night when everyone in Juling Villa was killed, it was the birthday banquet of the owner Wu Chengze, after a busy night, the village was already exhausted, and it was normal to drink some tea to quench their thirst, and this tea mixed with the source grass was enough to make everyone in this Juling Villa fall into fainting instantly, but I am afraid that they don't know how they died when they die."

Ye Qingtang's unhurried words made Zhou Xuan and the others turn pale in an instant.

They had already found out that all the dead in the Spirit Gathering Villa did not make any resistance before they died, and they were still suspecting whether they had been poisoned, and they had also probed those corpses with silver needles, but the silver needles did not turn black.

They thought they were thinking in the wrong direction, after all, even the basic drugged would cause the silver needle to turn black.

However, they never imagined that the murderer would use the unrefined Broken Source Grass.

Although the Broken Source Grass has the medicinal effect of causing people to faint, it is not toxic, so no matter how much they try, it is impossible to get results, and the Broken Source Grass is so finely crushed that once it enters the abdomen, it is mixed with flesh and blood, and it cannot be found at all!
