"What kind of water is this? Do you know?" Zhang Yu glanced at the five middle-aged men.

"I don't know. We have all been here." The five people said in a bitter way.

Look at their cowardly appearance, Zhang Yu could see that they were not lying.

Zhang Yu looked around and then found something. On the mouse cage, there were not only bowls for food, but also water.

He walked to a mouse cage, and these mice were bullying the weak and afraid of the strong. They seemed to see that Zhang Yu was powerful and all of them shrank back.

Zhang Yu looked at the bowl inside and sniffed it hard. There was a similar smell inside the bowl, but it was lighter and not as rich as in the bucket.

It is not difficult for Zhang Yu to guess the trick when feeding rats with this kind of thing. The reason why these rats can grow so big is that they drink these water.

After thinking about it for a while, Zhang Yu said, "Let's go out and keep moving forward."

"Okay. OK." The five old men hurriedly followed Zhang Yu out after being pardoned.

They led the way in front of the front, walked more than ten steps, and came to a stone chamber again.

This stone chamber is basically the end of the passage.

The stone room was also pitch black and there was no way to see it. However, there was no abnormal sound.

Zhang Yu threw two fire-gathering talismans into it, and there was light inside.

Looking inside, there are iron racks around it, and there are bottles and jars on them. In the middle of the stone chamber, there is a long iron table and two chairs, which look a bit similar to the previous laboratory.

"Go in and take a look." Zhang Yu ordered.

The five people took the lead in, and Zhang Yu followed him into the stone chamber. There was nothing unusual inside, but he could see it more clearly.

Some of the bottles and jars on the shelf are porcelain and some are glass. In some glass jars, many of them are known to Zhang Yu, which are traditional Chinese medicine.

On the iron table, there are many small glass bottles, most of which are liquid, transparent, red, blue, and black.

After seeing these clearly, Zhang Yu was even more sure that this was a drug laboratory. What kind of medicine is being studied? It is probably impossible to be a good thing.

"Um?"

Suddenly, Zhang Yu saw a brocade box on the table.

Zhang Yu pushed a middle-aged man and said, "On the past, open the brocade box and see what's there."

"I" is shocked.

"It's you!" Zhang Yu was straightforward.

The middle-aged man had no choice but to walk to the table and carefully open the brocade box.

Fortunately, nothing unusual. The middle-aged man walked up to Zhang Yu with a box and honestly presented it to Zhang Yu.

Together with Zhang Yu, there is a thicker diary in the box. Looking at the cover of the notebook, it seems that it has been a lot of years. Next to the notebook, there is an arrow. The arrow is very short and looks like a sleeve arrow in a costume film. The sleeve arrow is already rusted, but blood stains can be seen hanging on it.

"What's so special about this thing?" Zhang Yu reached out and lifted out the rusty sleeve arrow.

The sleeve arrows look cleverly crafted, and it is inevitable that the arrows look very sharp now. The blood on them has long condensed into black and mixed with rust, but there is still a hint of green at the arrows.

"There is poisonous on the sleeve arrow..." According to Zhang Yu's experience, after seeing the green green, you can directly confirm that the arrow is poisonous.

Obviously, this sleeve arrow has hurt people, but it is unknown who it is shot. The Jade King obviously attaches great importance to this thing.

If this arrow hurts the enemy of the Jade Heaven King, it should not be preserved according to reason. Zhang Yu’s guess is that the person injured by the sleeve arrow is likely to be very important to the Jade Heaven King, and perhaps it is the closest relative of the Jade Heaven King.

After thinking about it, Zhang Yu first put the sleeve arrow into his sleeve and then picked up the notepad in the brocade box.

The notebook was very thick. He opened it, and the handwriting on it was neatly crafted, like a big boy's font. Not only that, looking at the new and old paper, it was also a bit old and turned yellow.

Zhang Yu looked at it and said, "Boyellow, cuckold, ponytail, xanthus, white flower snake grass, half-branch lotus, cypress on stone, heartbreaking grass, crow courage..."

These are the names of traditional Chinese medicine. As long as you recognize them, Zhang Yu can immediately identify what the prescription is for.

This prescription is used to detoxify, among which the saccharinis is even more used to fight against the poison. However, in order to restrain the toxicity of the saccharinis, it is inevitable to match some medicines. Not only that, many of the medicinal materials here are mainly aimed at the lungs, which can regulate and protect the lungs and lung meridians.

"It seems to be used to treat people. The patient should be poisoned, and the main location should be the lungs." Zhang Yu gave a brief analysis and made a conclusion on this prescription.

After turning this page, there is another prescription. The medicine has similarities with the one I just said, but it is also a little different. There are seven medicines with slightly strong antidotes.

The so-called medicine is three parts poisonous. The greater the medicine, the more it is, it is inevitable that it contains toxins. Especially antidotes, sometimes they use poison to fight poison.

He continued to look down and it was still a prescription. This prescription was even more ruthless than the previous one, and there were many places on the paper that were hooked off. He obviously studied the entire prescription many times, and he actually used more than ten pieces of paper before he was confirmed.

After reading this prescription, Zhang Yu couldn't help but secretly admire that this person's medical skills are definitely not simple.

He continued to read again, and it was still a prescription.

This prescription can be written for more than twenty pages, which is also a modification.

Through this prescription, Zhang Yu was able to confirm that the third prescription should be to relieve the patient's poison. However, the medicine was too strong and injured the patient's lungs, so the fourth prescription was to treat the patient's lungs and drive away other drugs to repel the residual poisons.

After turning it over, the fifth prescription appeared. This prescription is used to repair lung meridians for the patient. This prescription was developed after more than twenty pages of paper.

After reading this prescription, Zhang Yu couldn't help but shake his head. In his opinion, this patient may never be saved. How long he can live depends entirely on luck.

The reason is that the person who is studying this prescription has already started to stitch and repair it. He will treat wherever there is a problem, but this treatment can only be endless treatment. The patient's lungs must be less than one day.

Next was the sixth prescription. After only a few glances, Zhang Yu shook his head again.

As I expected, the patient was no longer able to succeed. Those who prescribed the medicine added poppy flowers to the medicine. Adding this can make the patient feel better. After that, it will be maintained by poppy flowers.

He turned down again. The prescription he saw this time made Zhang Yu a little confused because he didn't know anything except poppy flowers in this prescription. Some of them were chemical element symbols.

Zhang Yu glanced at the middle-aged man standing opposite him, and his eyes lit up. These people were drug-making and must know chemistry. He immediately said, "Come and see what the things written on it do."

"Yes." The middle-aged man quickly agreed, approached Zhang Yu, and looked at the prescription written on the notebook.
