Isolation is definitely necessary.

But Zhenren Guiyan is a stubborn old man.

Xiao Ran felt that if the thousands of suspected spiritual beasts in the Ten Thousand Beast Valley were packed away directly, the old woman might fight him to the death.

So, he left the Valley of Ten Thousand Beasts empty-handed and came to the White Jade Bone Tower to find Zhenren Gui Yan.

Master Guiyan was surprised when he saw Xiao Ran come out empty-handed and there was no record of hunting animals on the jade slip.

"Are there no spiritual beasts in the entire Valley of Ten Thousand Beasts that can catch the eye of senior brother?"

Hey, women, on the one hand, they are afraid that I will do too much, and on the other hand, they blame me for not doing too much.

Xiao Ran sneered in his heart.

"It's not a plague, it's a poison from the underworld. The Valley of Beasts is about to become a poison den."

"Netherworld Poison? How is that possible!"

Master Guiyan was suddenly shocked.

"There has never been a netherworld incident in the Valley of Beasts since it was built!"

Xiao Ran had a straight face and there was no joking in his tone.

"If you leave it alone, everyone in the Valley of Beasts will be immune immediately. You should report it to the sect immediately. I will go back and discuss a solution with my uncle."

Master Guiyan's face turned pale. Although she didn't understand what "universal immunity" meant, Xiao Ran asked her to report it to the sect, indicating that the matter was serious.

"I'll let Zhehui go to the main peak."

Of course, Xiao Ran could come up with a plan to treat the underworld poison alone and went to discuss it with his uncle. He just wanted to make the matter bigger and more realistic.

Half an hour later, Master Yinyue and Xiao Ran came to the Valley of Ten Thousand Beasts for an on-site inspection.

After entering the valley and taking a look, Master Yin Yue confirmed Xiao Ran's opinion...it was indeed the underworld poison!

And unlike ordinary underworld poisons, it is not highly toxic and transmissible, but it is highly latent and extremely concealed. If Xiao Ran hadn't personally dealt with it, it could easily have been mistaken for an ordinary plague.

Xiao Ran felt that this was probably an immature experimental model.

If this underworld poison becomes more transmissible and even infects humans, it can directly bring disaster to the world of cultivation.

"Why didn't you inform me about such a big thing until now?"

Master Yin Yue reprimanded.

This was the first time that Xiao Ran saw his uncle being so strict.

Master Guiyan was so frightened that his face turned green.

"My nephew thought it was just an ordinary plague. After all, there have been no netherworld incidents in the Valley of Ten Thousand Beasts... Uncle Yinyue, is there any hope of salvation in the Valley of Ten Thousand Beasts?"

Master Yin Yue nodded.

"It is not difficult to get rid of the underworld poison, but the antidote to the underworld poison may contain some very rare ingredients, which cannot be prepared in a short time. The infected spirit beast must be isolated."

"How to distinguish infected spiritual beasts?"

"I will take a sick sheep back to Baicao Peak first, and study it with my nephew to see if we can refine a potion that can detect this kind of poison."

Junior brother Xiao also has talent in medicine? Can Master Yinyue be willing to study with him humbly?

Master Guiyan did not dare to say anything.

That night.

Xiao Ran and his uncle studied in the alchemy room all night, repeatedly considering the dosage ratio of the medicinal liquid, and finally developed a test poison with an accuracy rate of over 90%.

After a night of hard work, ten jars of potion were refined.

Yinyue wiped her sweat and straightened her clothes. Her body was tired, but her complexion was as rosy as a girl's.

It feels like it’s been a long time since I’ve had such a hearty experience refining medicine. I’ve wasted my life for thousands of years, and my best friend is actually a junior.

Xiao Ran was not satisfied yet, so he added ten times more medicinal dregs to Shitan Potion, turning it into Baitan Potion.

Then I asked my uncle to add a seal and seal it.

Master Yinyue was puzzled, but he always felt that Xiao Ran had some deep meaning.

"What does this mean?"

Xiao Ran explained without changing his expression:

"Increase sensitivity, reduce accuracy, catch more suspected spiritual beasts and isolate them to prevent any fish from slipping through the net."

Master Yin Yue frowned slightly, thoughtfully.

"You want to sacrifice a large number of healthy spirit beasts to ensure the isolation of all poisoned spirit beasts. Are you so cautious? Do you suspect that the poison will evolve?"

Uh... Although I didn't mean it this way, you came up with the truth through your random thinking.

"In my hometown, this is called virus mutation."

The dignified and charming face of Master Yin Yue suddenly revealed a girl-like curiosity and yearning.

"If you have the chance, can you take my uncle to visit your hometown? The alchemy skills there must be very strong."

"No matter how powerful the alchemy skills are, they can't cure Ziyou and Panzi. Learning medicine can save one person, but it can't save the world. People want to die, and gods can't save them."

Master Yinyue nodded, thoughtfully, and seemed to have some realization.

"I didn't expect that my nephew is also a person with stories at such a young age..."

the next day.

Xiao Ran came to Baicao Valley with a hundred jars of poison test sealed by Master Yin Yue.

Master Guiyan personally unsealed the hundreds of potions, sprinkled the potion with his sword over the Valley of Ten Thousand Beasts, and then cast a spell to let the potion penetrate into every spiritual beast.

Two hours later.

Gui Yan was dumbfounded.

There are more than 1% confirmed cases of spirit beasts in the entire Ten Thousand Beasts Valley, and as many as one-third of suspected cases!

Xiao Ran had a stern look on his face.

"Look, now you know the seriousness of the matter!"

Master Guiyan's voice was trembling. She couldn't imagine what kind of hell the Valley of Beasts would have turned into if Xiao Ran hadn't come.

Just this amount...

Her voice was trembling.

"Are there really so many poisoned spirit beasts? Are there any misdiagnoses among them?"

Xiao Ran suddenly became serious.

"Nonsense! Of course there are misdiagnoses, and there are quite a few of them, but the purpose of misdiagnosis is not to miss any confirmed cases of poisoned spirit beasts. I will keep the suspected cases. Do you dare to ask for it?"

Master Guiyan reluctantly waved his hand.

"Junior brother, let's take him away."

Only then did Xiao Ran take away more than ten thousand spiritual beasts openly and honestly.

The system space is really big enough!

After Xiao Ran left, in just two hours, the Valley of Ten Thousand Beasts returned to full vitality.

Although Master Guiyan's heart was bleeding, the gloom on his face was swept away.

Soon, Luo Sheng of the Discipline Hall came with two Herrschers to investigate the Valley of Ten Thousand Beasts.

After confirming that the Valley of Ten Thousand Beasts was restored to life, he credited Xiao Ran with a credit, allocated 10,000 spirit stones as a reward, and continued to pay attention to the progress of the underworld poison.

Xiao Ran: Have I made a meritorious deed again?

I came back and conducted in-depth research and found that this poison is not very toxic, but it is extremely difficult to get rid of. It does require some high-end and precious medicinal materials.

Xiao Ran spent a lot of effort and finally found the person who was diagnosed with the poison.

A few confirmed black goats were left for the uncle for research, and more than 300 confirmed spiritual beasts were kept alive and fresh in the system space, waiting for the uncle to refine the antidote.

In addition, more than 10,000 "suspected cases" that were confirmed to be healthy were not returned to the Valley of Beasts and were all euthanized by Xiao Ran.

The beast elixir is completely swallowed, turned into spiritual energy, and immersed in the sea of ​​​​qi.

Most of the animal meat and furs were taken to Dongfu City and sold.

Although the unit price is not high, the advantage lies in the huge quantity, selling 10,000 spirit stones.

In addition, the several thousand kilograms of high-grade wheat that Xiao Ran collected in Baili Qingfeng's secret warehouse to enrich his own pockets were also sold for more than 10,000 spirit stones.

In this way, Xiao Ran would have thirty thousand spiritual stones.

Master doesn't know about this money, he plans to save it for critical use.

Some of the remaining animal meat is barbecued and served with wine, some is used with hot pot with meat, and some is refined and dried into dried meat for storage.

In addition, some high-grade grains were left, part of which was brewed into Gaoling rice wine and malt liquor, and part of which was made into biscuits and cakes.
