The corners of Yan Wuling's eyes curved slightly, An Zhe's words made her originally low mood better, and even that bit of fatigue disappeared.

"You go and search the nearby mountains first, if you find clues, you must tell me, and I will investigate the origin of these poisonous powders and see if I can make an antidote."

She was worried at the thought of those who had grown old inexplicably, wondering if she could find a way to crack the poison powder.

"Okay, I'll take someone to search the mountains near the treasure village first, and I'll come and tell you immediately if there's any movement."

An Zhe looked around and found nothing unusual, so he was relieved to take someone to search.

Changyin led her men to comfort those who had woken up, patiently explaining to them what had just happened.

They didn't expect that they were almost murdered, if it weren't for Yan Wuling and An Zhe who saved them even if they appeared, maybe they would be like those who are getting old.

"Thanks to the prince and Miss Yan this time, otherwise we wouldn't know what to do."

Those who came to their senses arrived, gratitatively pulled Yan Wuling, and thanked her emotionally, Yan Wuling did not change anything because of their words, and his expression was still as calm as ever.

"You don't need to thank us, it was our responsibility to investigate this matter clearly, and the most important thing now is to investigate and deal with the truth behind it, and you had better be vigilant during this time, so as not to be taught by those people."

Yan Wuling didn't know what the purpose of those people was for a while, but no matter what their purpose was, she wanted to protect the people in the treasure village and didn't want them to have any more mistakes.

They nodded, knowing that the treasure village was not safe at the moment, and they had to be more careful than usual in their every move to save their lives.

After Yan Wuling explained that they should pay attention to safety, she instructed Changyin to send her soldiers to guard in the woods outside the treasure village to prepare.

She knew that those people didn't succeed, and there must be some action in the future, and the first to suffer at that time were the survivors of the Treasure Village.

"Changyin, I'll leave it to you first, I'm going to find out the source of these poisonous powders, these days, don't let anyone interfere with me."

Yan Wuling said to her in a serious tone that she hated others disturbing her the most when she was investigating, so she told Changyin in advance, lest someone break in at a critical time when she was investigating.

"Don't worry, I won't let anyone disturb you, but if the prince comes to look for you, I can't guarantee that I will be able to stop you."

Changyin replied that she could stop the others, but it was impossible to stop An Zhe, after all, An Zhe would not listen to her.

"He doesn't have to stop him."

Yan Wuling frowned slightly, just now she forgot to tell An Zhe not to come in and disturb her when she was investigating the poisonous powder, he would definitely come to look for her after he finished searching.

Thinking of this, she felt a little headache, but now there was no way but to take one step at a time.

"Okay, you go investigate, I will protect the people here and won't let you have any worries."

Changyin swore that until she investigated and understood that these poisonous powders were of great importance, she would definitely do her best not to let Yan Wuling have any worries.

"With your words, I am relieved."

Yan Wuling bowed slightly, and after saying goodbye to Changyin, he went straight to a thatched hut in the deepest part of the treasure village, which looked very simple.

However, there are many records of poisons, as well as some rare herbs that are not found in ordinary places.

Yan Wuling arrived in the room, looked at it for a long time, and after confirming that there was no one, he took out the Xuantian bracelet from his arms.

As soon as the Xuantian Bracelet was taken out, a faint light lingered in the whole room, Yan Wuling brought the powder she scraped on the paper close to the Xuantian Bracelet, and in less than a moment, the origin and name of the poisonous powder appeared in her mind.

It turns out that the name of this poisonous powder is called the Soul Forgetting Pill, which is a kind of poison in the Five Kingdoms Continent, and it only takes a fraction of a minute to kill people, so it is worth a thousand gold, and it is impossible for ordinary people to find this poison.

Thinking of this, Yan Wuling's brows furrowed even tighter, it seemed that the mastermind behind the scenes not only had an unusual identity, but was also very likely to be proficient in poison.

After all, this poison is very rare, and ordinary people don't know that this poison exists, let alone can use it so much at once.

Yan Wuling repeatedly recalled in her mind the person she thought was the most likely in her impression, but she thought about it for a long time, but she still didn't have the slightest clue.

But before she could figure out what the identity of the mastermind behind it was, there was another question that stumped her and made her puzzled.

She just focused on the identity of the mastermind behind it, ignoring a more important question, that is, this kind of poison is generally only used to kill people, how can it make so many people grow old overnight in an instant?

Yan Wuling couldn't figure out why this was at all, she just felt that this puzzle was like a huge net trapping her inside, and she couldn't find a way out.

She brought the powder closer to the Xuantian Bracelet, and her intuition told her that these powders might not just be Soul Forgetting Pills, maybe there were other ingredients in them, otherwise it would not cause so many people to grow old.

Yan Wuling's intuition was indeed right, these powders were not just Soul Forgetting Pills, there were also a large number of Broken Appearance Pills, and the weight of these Broken Appearance Pills far exceeded that of Soul Forgetting Pills.

So much so that the toxicity of the Broken Rong Pill overwhelmed the toxicity of the Soul Forgetting Pill, so the poisoned person will first show the appearance of rapid aging, and then his life will fail, creating a bizarre and strange phenomenon to confuse others.

Although this kind of poison is very rare, it doesn't seem complicated to Yan Wuling, and it can even be said that it is obvious that what she can't figure out the most is the person who drugged it, how did he poison it unknowingly, so that everyone didn't notice it, otherwise she should know it at a glance, and how could she not find out until now.

Yan Wuling put this puzzle aside first, and then took out a black bone left after Li Mao's poisoning and death before and investigated it with the Xuantian Bracelet.

She wanted to know what kind of poison this poison was, so she had no clue, and she could even say that she didn't have any clues, but what Yan Wuling never expected was that Xuantian Bracelet couldn't find out what kind of poison he was.

Yan Wuling didn't give up, and investigated again, but still couldn't find any clues, which can show that this poison is indeed what she inferred before, and the poison is undetectable when it enters the human body.

In this way, Yan Wuling felt that it was even more tricky, if he couldn't find out what kind of poison he had, how to investigate it next, wouldn't the clue be interrupted here.

Yan Wuling knew that this matter was more complicated than she had imagined before, so she put even more effort into it, but no matter what method she used, she couldn't get any clues that she could continue to investigate.

She took down all the books in the room that recorded poisons, and flipped through them page by page, just to be able to find out what kind of poison it was, so that people could not realize it.

An Zhe led his subordinates to search the entire mountain of the treasure village, and even took the nearby hundreds of miles from house to house.

But the result was unexpected, and the people under his command replied that there was nothing suspicious nearby.

"Are you sure there's really nothing suspicious around here?"

An Zhe asked suspiciously, the mastermind behind the scenes had obviously only done it before, could it be that he had grown wings, otherwise how could he have left the treasure village in such a short time.

Seeing An Zhe's gloomy face, his subordinates only felt a powerful momentum rushing towards him, and they trembled unconsciously when they spoke, for fear of angering him.

"Back to the prince, this is a hundred miles away, but we have collected it door to door, it is true, there is nothing suspicious, and this neighborhood is sparsely populated, and the mastermind behind the scenes may have fled."

The trembling reports of his subordinates made them search all the places where the mastermind behind the scenes could hide, even the wilderness and mountains, but they did not find any suspicious clues.

"Go down."

An Zhe sighed heavily, knowing that most of the masterminds behind the scenes had already fled, and now they could only stand still for the time being, waiting for his next move.

Remembering that when he left with his subordinates, Yan Wuling told him that she wanted to investigate the poisonous powder and didn't know what the situation was now.

He hurried back, and as soon as he went back, he couldn't wait to inquire about Changyin Yan Wuling's whereabouts, Changyin had already expected it, so he was not surprised.

"She's in a hut in the deepest part of the woods in the Treasure Village."

Changyin said helplessly, after An Zhe got the answer he wanted, he went to the hut satisfied, and as soon as he entered, he saw Yan Wuling sitting on the ground with a confused look in his eyes.

Yan Wuling's eyes were confused, her expression was a little trance, she had no clue for several days, she naturally felt anxious, and not only did she have no clue about the poisonous powder, but even the clues were broken.

An Zhe's anxious appearance disturbed her even more, if it weren't for his identity, Yan Wuling would have been eager to drive him out directly.

At this time, she didn't want anyone to see it, but Yan Wuling also knew that An Zhe's appearance was not deliberately trying to disturb her, but just a good heart.

"How? Did you investigate anything? ”

An Zhe could see that Yan Wuling was not in a very good mood, and asked cautiously, lest he poke her sore spot, and his expression became a little more cautious.

"No clue."

Yan Wuling spit out four words to herself, she told An Zhe all the results of her investigation in the past few days, and explained to him the reason why she couldn't figure out the poisonous powder.

An Zhe knew that he couldn't help in this regard, so he could only do it in a hurry, and after Yan Wuling eased his emotions a little, he remembered that An Zhe was going to search the mountains near the treasure village, and he didn't know if he had found any useful clues.

"What about you? Did you find any clues? ”
