Now what the eighth prince has to do is to save his life first, and then he can talk about how to deal with the prince, if he doesn't even have his life, let alone who he wants to deal with.

The night passed quietly, and she searched almost all the poisonous weeds, but still did not find the familiar smell, which made her very frustrated.

The comparison of the whole night made her too tired, she got up from the chair and moved her body, since she didn't find it, she could only look for it slowly.

Although she has a lot of poisonous weeds here, it is impossible to collect all the poisonous weeds, after all, there are countless poisonous weeds in this world.

She walked around the table and prepared to leave the room, it was already dawn, and it was time to go to bed after breakfast.

And she sniffed lightly as she passed by the table, froze for a moment, and then lowered her head.

What caught my eye was a withered yellow grass, lying there quietly, if it weren't for the fact that someone who was well versed in medicine saw this grass, he would have thought it was just an ordinary grass.

Yun Xiaoshuang picked up the grass and put it under her nose and sniffed it vigorously, and then a look of surprise appeared on her face.

The grass exudes a pungent fragrance, the smell is very strong, not so good, but the smell is extremely familiar.

She took out the small jade bottle from the box, and when she opened it, the whole room was filled with a fishy smell, and she sniffed it carefully.

Sure enough, there was a pungent fragrance in the fishy smell, which was exactly the same as the smell of the grass.

She never doubted her nose, because it was her best weapon and her greatest talent.

Since the taste of the two things is exactly the same, it is likely that this toxin was extracted from this small grass.

But Xiaocao didn't have that fishy smell, and the smell wasn't strong enough, she frowned and thought about it, and finally thought of a solution.

She took a fire fold from her bosom, then picked up the basin in the room and lit the grass, which was not burned as the flame burned.

The burning speed was very slow, which surprised Yun Xiaoshuang.

This kind of grass is best at hiding itself, it looks like an ordinary grass, but it's actually very scary.

There aren't many herbs or poisonous weeds that can withstand the burning of flames like this, and that's enough to see that this little grass is not ordinary.

As time passed, an hour passed, and the grass was burned off a little by the flames, and then turned into drops of green liquid and fell into the basin.

She hurriedly picked up the basin, and as soon as she lifted it, a fishy smell instantly filled her nostrils, and she was immediately so surprised that she threw the brazier on the ground, excited.

Now it can finally be determined that the deceased was poisoned by this grass, which smells exactly the same as a green liquid after burning, and it is poisoned to the deceased after burning.

Although she knew what poison it was, she didn't know this little grass, no matter how she looked at it, this little grass looked like an ordinary little grass, and it was even a little yellow.

But this room was not only her laboratory, but also her study, with two huge bookcases standing on either side of the room, filled with books.

Of course, these books were all prepared by Lin Jiyuan, and her books were only a few medical books in the middle of the bookcase.

These medical books have been handed down from ancient times, and they contain many interesting and useful things.

There was a book about herbs and poisons, and she pulled out the book, then picked up the last grass from the table and began to search for it.

She had thought that such an ordinary-looking poison was common, but just after searching, there was only one left in the room except for the one she had burned.

This made her very strange, it stands to reason that these things should be prepared a lot, right, is this thing hard to find?

Thinking of this, she opened the book with doubts in her head and began to look for it.

The book is very thick, and it contains a large number of medicinal herbs and poisonous weeds, and the records are very detailed, and even the best places to grow are clearly written.

It was also very time-consuming to find it from the book, but it was much better than comparing herbs, and at least she could brush up on her medical knowledge.

I don't know how long it took, but lunch had already been sent in, and it was Lin Jiyuan who personally sent it in, mainly worried about Yun Xiaoshuang's situation.

After all, he didn't come out all night, and in addition to this morning, there was no movement in the room at all, which made him very worried, so he naturally had to come in and have a look.

"Frost, haven't you slept all night?"

Putting lunch on the table, Lin Jiyuan asked with some distress.

"Well, grandfather, I'm fine, the matter here is more important, you go out first, I'll go out when I'm done."

Seeing that it was his grandfather who came in, Yun Xiaoshuang knew that it was because he was worried about himself, so he smiled casually.

Lin Jiyuan nodded, he knew that Yun Xiaoshuang needed to be quiet and couldn't be disturbed, so he didn't say anything and went out directly.

He just came in to confirm how Yun Xiaoshuang's situation was, and it looked like the situation was very good, and there was nothing big about it, so he could go out with confidence.

After lunch, she continued to conquer the medical book in her hand, comparing it with the grass to find out what this thing was.

It wasn't until the evening that she finally found it, and sure enough, it was also recorded in this medical book, and she compared it several times before finally confirming that it was indeed this thing.

The name of this small grass is called Soul Slayer Grass, which was born in ancient times, hundreds of years ago.

The formation of Soul Slayer Grass is very harsh, and it must be under the extreme sunlight of the sun to have a chance to grow, and it cannot be artificially planted.

Therefore, the number of Soul Slayer Grass is extremely rare, this thing is very poisonous, and the toxin of a Soul Slayer Grass can even poison dozens of horses, which is very terrifying.

And this thing only grows in a fixed place, and if you leave that place, it will wither and die, as for why these two plants have survived to this day, I don't know.

However, according to her guess, it should be mutated, after all, it is normal for a few strains to be different from others.

The secretary had the location where this thing grew, and she quickly took out the map of Tianshuo Kingdom and checked it.

In the end, it was determined that the place where the Soul Destroying Grass was located was in the southernmost part of Tianshuo Kingdom, Shicheng.

Although Shicheng is also a state, the name has not changed, and it is still called Shicheng.

She hadn't been there, but she had also learned that Shicheng was a place where birds don't poop, it was very biased, and it was sparsely populated.

The population of Shicheng as a whole is estimated to be less than that of a city in Mengzhou.

And there are poisonous insects everywhere, because the climate is very good, so many poisonous weeds grow there, and there are also many poisonous insects living there.

What's more, there is a naturally occurring miasma around Shicheng, which is extremely poisonous, so few people go anywhere.

Unlike other poisonous weeds, most of Shicheng's poisonous weeds can be transferred to other places for planting, so the number is very large.

However, the Soul Slayer Grass will wither and die as long as it leaves Shicheng, and it is rarely able to be taken out and planted, and the Soul Slayer Grass like these two is very special.

Thinking of this, she nodded secretly, it seems that the murderer is from Shicheng, after all, this thing is only known to Shicheng's people, and they can bring it out.

She put away the medical book, now that she knew this, there was no point in continuing to stay.

She walked out of the room and came to the front hall, where Lin Jiyuan and his wife were still drinking tea in the front hall, and they were still talking about Yun Xiaoshuang.

"Shuang'er, are you done? Look at your haggard appearance, quickly sit down and rest. ”

Lin Jiyuan was distressed when he saw Yun Xiaoshuang's dark circles, and hurriedly asked her to sit down.

"Shuang'er, what the hell happened, can you tell me this time?"

Lin Jiyuan asked softly, he was still very curious in his heart.

But it's more of a worry about her, and at first glance, she has encountered something very big, and if he can help, he will definitely be duty-bound.

Hearing Lin Jiyuan's words, Yun Xiaoshuang also said everything that had happened recently, not a word, after all, in the face of Lin Jiyuan, she had nothing to scruple about.

said that Wu Liuli told her that someone was going to make a move on her, and then a guy died in her money bank yesterday, which made it hard for her not to think that these two things had something to do with each other.

Then there was a night and a whole day of investigation, and Shicheng was the final result of the investigation.

"How could something like this happen? The crown prince's courage is too big, it seems that the emperor's situation should be very bad. ”

Hearing her words, Lin Jiyuan stood up directly from the chair, with an angry expression on his face, and he couldn't be angry.

He was angry that the prince was hiding too deeply, and the prince was a submissive, world-minded, and open-minded and studious person before.

And he behaved very honestly, which made people mistakenly think that he was a kind-hearted person who did not fight or rob.

But now that the emperor is seriously ill, he gradually reveals his ambitions, and his true character is also exposed.

The prince is actually a selfish, ruthless, and unscrupulous person who will do whatever it takes to achieve his goals, and he actually sees it clearly now, I have to say that the prince's acting skills are really good.

At this time, the emperor was seriously ill and fell, and the crown prince managed the government and did not let anyone see the emperor, Lin Jiyuan couldn't help but worry at this time.

He was worried that the crown prince would take advantage of this excellent opportunity to do something unfavorable to the emperor.

After all, the prince has been the prince for more than ten years, and with his character, it is estimated that he has long been eyeing the throne, and finally has such an opportunity, how can he let it go.

"The emperor is in danger, now the entire court is under the control of the prince, it can be said that he is the next emperor, if this continues, the emperor is in danger."

Lin Jiyuan sighed, with the current character of the crown prince, he is not suitable to be an emperor.

How can such a ruthless and vicious person manage a country well and keep a world, Lin Jiyuan knows this better than anyone else.

Because the current emperor was taught by him, he knows how to be a good emperor who is diligent and loves the people, and the prince is definitely not such a person.
