Among the information that Zhang Fan stole from the nano watch, not only did he know that the Forging Body Grass was helpful for his own Devouring Corpse Master's Blood Core, but he even knew the location of the medicinal field where the Forging Body Grass was located.

In fact, even if he didn't tell Yao Lao now, using the laws of the four-dimensional space to forcibly pick some forging grass back, no one would be able to find out that he did it.

But he hasn't been here for a long time, and he doesn't know much about this place, so if he can get the forging grass by serious means, try to use serious means.

By about five o'clock in the afternoon, Yao Lao finally returned.

From a distance, Zhang Fan saw a thin old man.

The cheekbones are so high that they can almost pierce the skin.

There were a few sparse hairs on his head and a few sparse beards on his chin, like dead grass in the desert.

The medicine elder walked all the way up the mountain, pointing out the inner disciples in the medicine field all the way.

"That ...... That's it, yes, hold it up for me......"

"Flowerless Qiao Mai must be protected from the light, can you cover him? Don't you see that the sun is shining on it right now? If one of these flowerless trees dies, you will be buried! ”

"Water this field more and water it more! Why is it called five-color rice? Why does it have the word 'rice' in its name? It's that it likes water by nature. If it dies of thirst, don't drink any water from the rest of you! ”

When those disciples heard Yao Lao's words, none of them dared to squeak, and hurriedly followed Yao Lao's instructions.

Yao Lao was obviously very angry by these disciples, and he was panting for breath.

When he saw Zhang Fan next to the medicine field next to him, he couldn't help frowning: "How can there be living people here?" Don't you know that my herbs don't smell of life? Boom away, boom away......"

Several disciples next to him immediately walked towards Zhang Fan.

Zhang Fan couldn't help but be speechless.

Herbs don't smell raw?

Sure enough, it's a weird old man.

However, he was not in a hurry, neither humble nor arrogant, and said: "Yao Lao, if you drive me away today, I am afraid that your secret disease will not be cured in this life." ”

"Dark disease? Cut, I have been studying pharmacology for 300 years, and to put it mildly, there is no disease in this world that I can't cure. Will I have a dark disease? You kid is looking for a fight! Come on, call me out! ”

As soon as Zhang Fan's body shook, he shook away the disciples who rushed towards him.

Then he said: "It is a medicine that is poisonous, and as long as it comes into contact with the medicine, it will be contaminated with the toxins in the herbs." However, the amount of these toxins is very small, so they can be excreted from the body with the body's new metabolism on weekdays. There is no harm to people. But Yao Lao is different, because you have been immersed in pharmacology for 300 years, and you have been dealing with herbs every day, and before you know it, these toxins will accumulate in your body.

"At first, I didn't think it was anything, but after a long time, as soon as there were too many toxins, it would affect your body, and it would have an impact on your cultivation and even your normal life. And the dark diseases in the medicine elder's body are caused by the accumulated toxins. ”

Hearing this, Yao Lao was slightly stunned, and then waved his hand, telling the disciples who were about to continue to pounce on Zhang Fan to retreat.

Then he looked at Zhang Fan seriously a few times and said, "Okay, even if there is a dark disease, with my three hundred years of pharmacological knowledge, can't I solve it?" ”

Zhang Fan shrugged his shoulders and said: "The so-called authorities are confused, and they don't know the true face of Lushan, only because they are in this mountain. Yao Lao has studied pharmacology very thoroughly, but he will inevitably not see his physical condition clearly. ”

Yao Lao originally thought that what Zhang Fan said before was just a bluff.

After all, this kid is only in his twenties, depending on his age.

Even if there is some research on pharmacology, how deep can it be?

Just by looking at it, you know that you have a dark disease, how bullshitty is this?

Yao Lao's secret disease is known only to him, and he has never mentioned it to anyone.

So the possibility of this kid inquiring in advance to find out the news is zero.

Could it be that he really only looked at himself and knew that he had a secret disease?

At this time, a disciple next to him asked, "Yao Lao, this kid ...... Still booming? ”

Yao Lao waved his hand and said, "Go and get busy with you." ”

When those disciples heard this, they all glanced at Zhang Fan in surprise.

A long time ago, there were guys who came here to make trouble, and they all beat them out.

And it's not enough to just not be able to fight, and afterwards Yao Lao has to find a way to make those boys remember for a long time.

After letting them do it once, they will not dare to do it again.

But what's going on today?

This guy is obviously messing around here, but Yao Lao didn't kick him out?

Could it be that this guy really has some skills?

However, although they had doubts in their hearts, they did not dare to disobey Yao Lao's orders, and they all retreated into the distance one by one.

Yao Lao turned his head at this time and asked Zhang Fan, "You said that I have a secret disease, but you can talk about it in detail." ”

"Yao Lao has accumulated a lot of toxins in his body because of his years of exposure to herbal medicines. However, because Yao Lao has already reached the realm of the Martial King, these toxins will not have any effect on your body. ”

Zhang Fan replied.

"That's true."

Yao Lao stroked his sparse beard and thought, "In that case, why do I feel dizzy and dizzy from time to time in the past few days, and I have symptoms of poisoning?" ”

"And a little constipated."

Zhang Fan added.

Yao Lao looked at Zhang Fan in surprise: Is this kid a fortune teller?

Do you know this?

Zhang Fan replied: "It's very simple, because Yao Lao has touched poisons recently: poisonous insects, scorpions, centipedes and the like. ”

Yao Lao was puzzled and asked, "How do you know?" ”

Zhang Fan naturally used a nanometer watch to detect all the elements in Yao Lao's body and analyzed it.

But of course he could not answer this, but said:

"These poisonous insects and scorpions, if they are used well, they are miraculous medicines, and if they are not used well, they are poisons. With the pharmacological knowledge of Yao Lao, it can naturally be used well. It's just that these things are inherently highly toxic, and their molecules will inevitably enter the body of the medicine elder, thus triggering the toxins accumulated over the years, which produces dark diseases. If my guess is correct, every time Yao Lao goes to the shade, he will have some pain and itching on his body. And in the sunny land, this feeling will disappear again. And there will be symptoms of constipation, and it is getting worse. ”

"That's right. Ever since I powdered some poisonous insects a month ago and made them into medicine, I often get dizzy. Whenever you go to the shade, you will feel itchy on your body. When you reach the sunny place, the itch will disappear. Constipation, which had never been seen before, also appeared. ”

Yao Lao suddenly said: "It turned out that the toxins of poisonous insects entered the body, causing the toxins accumulated in the past. ”

After Yao Lao finished speaking, he fell into deep thought and began to think about what medicine could be used to cure this dark disease.

But after thinking about it for more than ten minutes, I didn't come up with any solution.

Because the toxins accumulated in the body come from thousands of different herbs.

There is no antidote that can get rid of all the toxins.

You get rid of this poison, but you may activate another poison.

What's more, these toxins are not actually poisonous in the first place, so basically people don't care about such a little toxin.

It is almost impossible to find the poison for this toxin now.

After thinking about it for a long time, he couldn't think of any antidote, so Yao Lao turned his head and asked Zhang Fan: "So, do you have a method of detoxification?" ”
