Among the information Zhang Fan stolen from the nanowatch, he not only knew that the body-forging grass was helpful for devouring the blood core of the corpse owner, but also knew the location of the medicine field where the body-forging grass was located.

In fact, even if I don’t tell Yao Lao, using the four-dimensional space law and forcibly picking some body-forging grass back, no one can find that it was him.

But he has just been here for a while and doesn't know much about it yet, so if he can get the body-forging grass with serious means, try to use serious means.

It was around 5 p.m. that Yao Lao finally came back.

From afar, Zhang Fan saw a skinny old man.

His cheekbones are so high that they can almost expose their faces.

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

Yao Lao walked all the way up the mountain, guiding the inner disciples in the medicine field all the way.

"That...is that one, yes, hold it up for me..."

"The Wuhua Qiaomai must be protected from light. Can you cover him? Didn't you see the current sunshine shining on it? If one of these Wuhua Qiaomai dies, you will go and bury him!"

"Water more water in this field! Why is it called Wuse Rice? Why does it have the word "rice" in its name? It is that it is naturally fond of water. If it dies of thirst, you guys should not drink water in the future!"

When the disciples heard Yao Lao's words, they did not dare to say anything, and quickly followed Yao Lao's instructions.

Lao Yao was obviously very angry by these disciples and gasped.

When he saw Zhang Fan next to the medicine field, he couldn't help but frown: "How can there be strangers here? Don't you know that my herbs can't smell the strangers? Bomb it away..."

Several disciples immediately walked towards Zhang Fan.

Zhang Fan couldn't help but be speechless.

Can't smell the herbs?

It's indeed a weird old man.

But he was not anxious, neither humble nor arrogant, and said, "Old Yao, if you drive me away today, your hidden disease may not be cured in your life."

"Dark disease? Tell me, I have been studying pharmacology for three hundred years. If you say a big word, there is no disease in this world that I can't cure. I will have a secret disease? You guys are looking for a fight! Come on, call me out!"

Zhang Fan's body was shocked and he shook the disciples who rushed towards him.

Then he said: "It is a medicine that is three parts toxic. As long as you come into contact with the medicine, you will be contaminated with the toxins in the herbs. However, the amount of these toxins is very small, so it can be excreted from the body as the body sinks and metabolizes. It is not harmful to people. But medicine is different. It is precisely because you have been immersed in pharmacology for three hundred years and have been dealing with herbs every day. Before you know it, these toxins accumulate in your body.

"I didn't think anything at first, but over time, more toxins will affect your body, and it will affect your cultivation and even normal life. The hidden diseases in Lao Yao's body are caused by the accumulated toxins."

When Lao Yao heard this, he was slightly stunned, then waved his hand and asked the disciples who were about to continue to pounce on Zhang Fan.

Then he looked at Zhang Fan carefully and said, "Okay, even if I have a secret disease, can't I solve it myself with my three hundred years of pharmacological knowledge?"

Zhang Fan shrugged and said, "As the saying goes, those in the authorities are confused and do not know the true face of Mount Lu because they are in this mountain. Yao Lao has studied pharmacology very thoroughly, but he will inevitably be unable to see his own physical condition."

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 profound can it be?

By just taking a look, you will know that you have a hidden disease. How unreasonable is this?

Only he himself knew about Yao Lao’s secret disease and had never mentioned it to anyone.

So the possibility of this kid asking for information in advance is zero.

Could it be that he really knew that he had a secret disease just by looking at himself?

At this time, a disciple next to him asked, "Old Yao, is this kid... still bombarded?"

Lao Yao waved his hand and said, "Go and do your business."

When the disciples heard this, they all looked at Zhang Fan in surprise.

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

Moreover, it is not enough to just kill. Afterwards, Yao Lao still needs to find a way to make those kids remember.

After telling them once, they dare not commit again.

But what happened today?

This guy is obviously making trouble here, but Lao Yao didn't drive him out?

Is this guy really capable?

However, although they were confused, they did not dare to refuse to obey Yao Lao's orders and retreated to the distance one by one.

Only then did Lao Yao turn his head and ask Zhang Fan, "You said I have a secret disease, but you can tell me in detail."

"Because Yao Lao has been exposed to herbs for many years, he has accumulated a lot of toxins in his body. However, because Yao Lao has reached the level of King of Martial Arts, these toxins will not have any impact on your body."

Zhang Fan replied.

“It’s true.”

Yao Lao stroked the sparse beards and thought, "Since that's the case, why do I feel dizzy and poisoning from time to time in the past few days?"

“Also a little constipated.”

Zhang Fan added.

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

All of this knows?

Zhang Fan replied: "It's very simple, because Yao Lao has encountered poisonous substances in recent times: poisonous insects, scorpions, centipedes, etc."

Yao Lao was surprised and asked, "How did you know?"

Zhang Fan naturally used a nanowatch to detect all the elements in Yao Lao's body and analyzed them.

But he naturally couldn't answer this, just said:

"These poisonous insects and scorpions are used well, and if they are not, they are poisonous. With Yao Lao's pharmacological knowledge, they can naturally be used well. However, these things are highly toxic substances, and their molecules will inevitably enter Yao Lao's body, which will trigger the toxins accumulated over the years, which will cause dark diseases. If I guess correctly, Yao Lao will feel a pain and itchy feeling whenever he goes to the shady place. When he goes to the sun, the feeling will disappear. And there will be symptoms of constipation, and it will become more and more serious."

"That's right. Since I ground some poisonous insects into powder and made into medicine a month ago, I often feel dizzy. Whenever I go to the yin area, I feel pain and itchy. When I go to the yang area, the pain and itch will disappear. Constipation that I have never seen before has also appeared."

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

After Yao Lao finished speaking, he fell into deep thought and began to think about what medicine can be used to solve this hidden disease.

However, after thinking for more than ten minutes, I didn't think of any solution.

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

There is no existing antidote that can remove all toxins.

If you remove this poison, you may activate another poison.

Moreover, these toxins are not actually poisonous, so basically people don’t care about such a little toxin.

It is almost impossible to find a poison to relieve this toxin now.
