Just as Su Liuyu was full of thoughts, Dai He spoke again.

"If Your Highness really needs medicinal herbs, why don't you let Master Guo send someone to Yaowang Mountain for a trip?"

"He's going, does it work?" Su Liuyu was very skeptical.

After all, Gu Yan's body used to contain Ye Ying's heart.

"If it weren't for the people of the national master, His Highness might not be able to get the medicinal materials of Yaowang Mountain."

"How?" Su Liuyu was very curious.

"There have always been rumors in Gu Huaguo, it is said that almost no one survives who goes to the Medicine King Valley."

"Why? I've never heard of that. ”

Sighing, Dai He said quietly: "That kind of place is not something ordinary people can go to. ”

After pondering for a moment, Su Liuyu nodded and said, "Yes." ”

Even she knew that Ruan Lingzhi, a cherished medicinal material, was rarely cultivated in the world in Guhuaguo, let alone a place where this elixir could grow, and if she thought about it with her toes, she knew that ordinary people were not qualified to get it.

However, Su Liuyu soon thought of a new question.

"If the former Medicine King goes to travel around the Four Kingdoms, then, what will happen to the people of the Medicine King Mountain?"

"If the former medicine king does not return after two years of leaving the mountain, the medicine king mountain will re-elect the medicine king."

Although it was an expected answer, Su Liuyu still had some regrets.

"In this case, I'm afraid the rules of Yaowang Mountain have already changed."

"The slave doesn't know."

Shaking his head, Su Liuyu didn't continue to ask.

Anyway, she has the artifact of the system in her hand, so she shouldn't be able to find medicinal herbs everywhere.

Looking at the thick book next to him, Su Liuyu's head hurt again.

"You go out first, I'll watch later."

"Yes."

As soon as he raised his foot, Dai He suddenly remembered something, and said again: "If Your Highness wants to know about many matters in Yaowang Mountain, ask Master Guo, and you may be able to get the answer." ”

Nodding perfunctorily, Su Liuyu stared at the book in his hand intently, and replied casually: "Let's talk about it." ”

Seeing this, Dai He didn't say anything more, and retreated quietly.

At this time, Su Liuyu's eyes seemed to be glued to a book, and she couldn't move it anymore.

After a little bit of the ancient book, she finally saw the content about Gu worms.

"There is an insect in the western Xinjiang, called Gu, if it enters the human body, it can be a puppet and be commanded ......"

It's a pity that the content in front is complicated, and even the matter of feeding Gu worms is slightly involved, but suppressing Gu worms, Su Liuyu has gone through most of the books, and finally found a prescription without wasting his efforts in vain.

But looking at this coveted recipe, Su Liuyu's face became solemn.

"Bone Grass? Aracea? Isn't this still fighting poison with poison? ”

But knowing that this recipe was poisonous, Su Liuyu still insisted on reading it.

Fortunately, as she watched it, her brows gradually stretched a little.

"If the Bone Grass and Aracea are poisonous, then Polygonum multiflorum and Scutellaria baicalensis should be the effect of recuperation, as for other adjuvants, the effect of balance is greater......"

After muttering and analyzing for a long time, Su Liuyu finally understood this recipe.

After turning a few more pages and making sure that it was useless, Su Liuyu put down the heavy book and lay down on the bed again.

By the time she regained consciousness, she was already in space.

Reciting the recipe that Fang had just memorized, Su Liuyu looked at the light screen with a solemn face.

"It's up to you to mix the proportions, and the effect of the medicine will reach the best, right?"

"Are you suspicious of me?" The system is very unconvinced, "I'm an intelligent system!" ”

"Let's get it!"

On the blue light screen, all kinds of data flashed around quickly, and Su Liuyu was dazzled and had a headache.

But the benefits of having a system are also obvious, otherwise, she would be the one who is busy here now.

This prescription looks simple, but it is extremely difficult to experiment, and even the system has been grinding for half an hour, and there is only one more prescription list on the cooking table.

"This modified prescription has the same medicinal properties, but there are almost no side effects."

"Great!" Su Liuyu was about to jump up excitedly, "In this way, this recipe can suppress the Gu worms and make Gu Yan a little better, right?" ”

"More than that," the system denied, "it's not suppression, it's deception." ”

Su Liuyu looked dazed, and asked in a daze: "What is deception?" ”

"If you eat this pill, the two Gu worms will be deceived into sleeping peacefully, and for a long time, there will be no activity, and Gu Yan will naturally not be attacked by Gu poison."

"So, I have enough time to get points to cure him?"

"Theoretically, yes."

But after a few moments of joy, Su Liuyu remembered a new question.

"However, I remember that this kind of thing is highly poisonous."

"The poison will be slowly absorbed by the Gu worm after it wakes up."

"One last question," Su Liuyu stared directly at the light screen, "If it is suppressed this time, what will happen if the Gu worm wakes up again?" ”

After a long silence, the system slowly typed a line of words.

"Surely we will die."

"If he is immediately treated with points, will he be saved?"

"I'll do my best."

After listening to the system's words, Su Liuyu's expression was a little dazed.

Since she came to this world, she has always thought from the bottom of her heart that the system is an all-powerful guy, and no matter what happens to him, there will naturally be the best outcome.

But she didn't expect that for Gu Yan's illness, even such an unscientific existence as the system, she could only say one word, do her best.

After being stunned for a long time, Su Liuyu asked in a trance: "If you don't use this recipe, he ...... How long can you live? ”

"The half-moon period."

For some reason, Su Liuyu suddenly laughed.

"Half a moon...... It's a little longer than I thought it would be......"

After a while, Su Liuyu's eyes were much firmer.

"Exchange the medicinal materials on this recipe for me first."

"Have you decided you want to use it?"

"Of course, as long as you can let him live first."

Regarding Su Liuyu's risky move, the system didn't say much, but silently took out the medicinal materials.

This time, as usual, the herbs were fresh and dry.

But Su Liuyu couldn't notice these anymore, and her mind was completely occupied by Gu Yan's illness.

After getting up, Su Liuyu took the prepared medicinal materials and went straight to the study.

"My lord, I'm going to borrow your kitchen."

"Whatever you want." Gu Yan obviously didn't care.

Su Liuyu didn't explain too much, and went directly to the kitchen.

It was the first time in her history that she had been so carefully boiled, and even the size of the fire had to be checked from time to time.

Therefore, by the time the medicinal juice boiled out, the sky outside had already darkened, and Su Liuyu was also exhausted.

But looking at this small bowl of soup and medicine, Su Liuyu was still extremely pleased.

Carefully placing the bowl on the desk, Su Liuyu opened his mouth.

"Drink this medicine while it's hot."
