There is an inconspicuous small county town in the southwest of Wuzhou County called Wushan County.

Because of the inconvenient transportation and mountainous areas, the economic and population development is relatively slow, and it belongs to a relatively poor county, and Xiang Yun is here, once again as Mr. Yao, he found Lan Xiang who came to greet him.

When Lan Xiang faced Mr. Yao, who was not seen by Shenlong, she put away her momentum as the head of the Ten Thousand Demon Association of Wuzhou County, and greeted her respectfully like a disciple meeting a master.

Xiang Yun bowed slightly to him: "What about people?"

Lan Xiang hurriedly said, "Please come with me, teacher." ”

Xiang Yun and Luo Zheng were taken into a courtyard-style building.

When the two of them walked into the building, they found that there were several breeding sheds in this huge courtyard, and through the transparent glass, they could see all kinds of poisonous snakes and spiders.

A young man who looked sunny and handsome, around thirty years old, appeared here, this person was none other than Du Xu, a well-known alchemist he had seen at the debate conference.

"This is my teacher, you can call him Mr. Yao. ”

Lan Xiang first wanted Du Xu to introduce Xiang Yun.

She then briefly introduced Du Xu to Xiang Yun.

"This is the pharmacist Du Xu mentioned to you by the student, he was originally a rare genius pharmacist, and because he specialized in the field of poisons, he had achieved a lot of results, and he had a considerable reputation in Wuzhou County. ”

Du Xu's gaze fell on Xiang Yun.

Because Xiang Yun was wearing the mask of the Night Watchman, he couldn't tell Xiang Yun's identity and strength, but Du Xu noticed Luo Zheng and keenly felt that Luo Zheng was at least a Tianmai master, and he was very strong and dangerous.

The entourage is all Tianmai masters?

And can a woman like Arashika apprentice?

Who the hell is this Mr. Medicine? Why have I never heard of it?

Du Xu's eyes narrowed slightly, he didn't dare to have a sluggish mentality, he immediately put on a modest posture, bent down and made a junior salute, "Mr. Yao can have a high apprentice like Lan Xiang, and the junior doesn't dare to be a genius." ”

"Don't waste time. Xiang Yun said in a hoarse voice: "I heard that you can find the most poisonous thing, where is this poison!"

It's really shameless.

But Du Xu didn't care.

People are high-ranking seniors, and it's normal to have a big temper.

"Don't hide it from Mr. Medicine, this extremely poisonous thing is sealed in a cave in the depths of Wu Mountain at this moment!"

Wushan Mountain is a group of mountains on the south side of Wushan County.

There are not many other things in this mountain, poisonous weeds and poisonous insects are everywhere, and the residents of Wushan County only feel that they are circling around the periphery, and few people have the courage to set foot in the depths of Wushan Mountain.

Xiang Yun asked, "So, how can you be sure of the location of this thing?"

Du Xu seemed to remember some sad past, sighed and said slowly: "This cave was originally a place used by the ancestors of the family to cultivate poisons, and it has been passed down in our vein for more than two hundred years. But ten years ago, an accident caused the cave to be closed, and even the family teacher died tragically in it......"

His face was gloomy and sad as he spoke.

Xiang Yun listened to a rough idea, this person was obviously a descendant of a certain folk inheritance.

This kind of folk inheritance relationship is still very common, and this form of master-apprentice inheritance is recognized by the government, and there is even a special registration office, just like obtaining a marriage certificate.

The relationship between Xiang Yun and Lan Xiang is similar to this relationship.

Of course, they didn't bother to testify.

After all, it's only named.

A true master-apprentice inheritance will have a lot of personal goods to teach each other, so the relationship will be longer and closer than that of teachers and students in school, and even more important than relatives.

Du Xu's ancestor is a top old poisoner.

At that time, a cave was opened in Wushan Mountain for cultivating poisons.

The method they used was a bit similar to the Gu refining method of the Baiyue Gu Master, which was to throw a large number of poison monsters they caught into this cave, let them drink the poisonous water in the cave, and the feed they fed was also specially refined poison.

Sometimes, poisons will kill each other, swallow and absorb.

In the end, the toxicity becomes more and more violent, and the final material is of higher quality.

Three years ago, there was an accident, and it was this accident that gave birth to a super poison.

"When the family teacher and I entered the cave, there was never a hundred-year-old centipede demon that changed, not only did it awaken its wisdom, but also broke free from the cage and launched an attack on us. ”

"The master was so poisoned that he couldn't escape death, so he could only throw me out with his last strength and seal the cave at the same time. ”

"This centipede demon is the strongest of the poisonous demons raised in the cave, when the master captured it, it has been cultivated for more than a hundred years, and after more than ten years of cultivation in the cave, I never thought of sudden mutation and evolution, which is even more extraordinary...... And now that three years have passed, the centipede demon that is out of control will definitely devour other poisons in the cave, and now it must be even more powerful, and it will be very risky to deal with it. ”

What a sad past.

Du Xu, this guy is a six-vein cultivator.

Xiang Yun estimated that his master's cultivation was definitely higher, that is to say, he was a medicine master with a seven-vein cultivation.

Although the medicine family's combat power is not strong, it was instantly attacked and killed by a spirit, which is enough to show that the strength of this spirit is around the seven veins, and after more than ten years of careful cultivation by a top poison refining master, I don't know how many poisons have been devoured......

It is not too exaggerated for Du Xu to call it the most poisonous thing.

Lan Xiang asked Xiang Yun carefully, "What do you think, teacher, does it meet your requirements?"

"Almost. Xiang Yun's eyes fell on Du Xu, "Labor leads the way, and in terms of compensation, I won't treat you badly." ”

A hint of discoloration flashed in Du Xu's eyes, but he hurriedly said: "It's just a trivial matter to lead the way for Mr. Yao, and this centipede spirit killed the family teacher, and there is a common enmity with Zaixia, Mr. Yao and Miss Lanxiang are willing to take action, and it is too late to be grateful, how dare they take revenge?" It's just that the things left by the family master in the cave are all ......."

"All I need is this centipede spirit, and nothing else. ”

"It's the best of course. Du Xu breathed a sigh of relief, "The centipede cave is extremely dangerous now, I think we should make some preparations." ”

Xiang Yun said without hesitation: "There's no need, don't waste time, let's set off now." ”

"Ah, but, this centipede ......"

"Less verbose. Lan Xiang couldn't help but say: "The teacher said that there is no need, there is no need for this, it is just a centipede essence, and the teacher will definitely be able to catch it by himself!"

Joke.

Who is Mr. Yao?

A hundred-year-old centipede essence is nothing!

Lan Xiang has absolute confidence in Mr. Yao's ability, and last time even the Abomination Kraken in the sea was all said by Mr. Yao, how could he misjudge a mere centipede essence.

Even if this centipede essence is very powerful.

Lan Xiang thought that Mr. Yao was very likely to be a senior who was no less than the Nine Veins, and even suspected that the other party was a peerless master of the Immortal Realm, no matter how weak the medicine master's combat power was, once his cultivation reached this level, it was not something that ordinary people could imagine.

Du Xu's persuasion was ineffective.

However, considering that Mr. Yao's disciples and retinue are all Tianmai masters, that entourage must be a powerful existence, and Lan Xiang, as a demon clan, has strong combat effectiveness, so the combat power of these two should be about the same.

Since this is the case, there is no nonsense.

He immediately led the way and led a few people into the mountains and forests.

Xiang Yun was actually quite depressed at this time, because it stands to reason that if he wants to continue to play the identity of Mr. Yao, he must try to avoid such an action with Lan Xiang.

He knows for himself what level he is!

If you're not careful, you'll be able to goof.

If Lan Xiang's true identity is known, the fun will be a bit big, and it is estimated that Lan Xiang's three views will collapse by then...... That's not going to be fun.

But Xiang Yun didn't have a better way.

Now compared to this, Senior Sister Jiang's matter is more important, and she can only take one step at a time.

"We're here!"

Du Xu is a pharmacist, his physical strength is relatively weak, and he is already a little tired at this moment after high-intensity mountain travel.

The four of them are in a huge basin valley at the moment.

This valley is not only filled with poisonous miasma, but also full of poisonous strange flowers and plants, Du Xu took the antidote medicine in advance, so it's okay, Lan Xiang relied on the body of the demon clan who was born to run rampant in nature, although he felt a little uncomfortable, but it was not so much that he couldn't bear it.

As for Xiang Yun and Luo Zheng, of course there is nothing at all.

With this bit of poisonous mist and poisonous pollen, Xiang Yun didn't even need to activate the holy blood, and he could easily resist with only a small amount of holy blood that naturally flowed in his body.

Luo Zheng is a real poison-free physique.

He's not even a living person, he's just a corpse king, who has ever seen a zombie that will be poisoned?

Xiang Yun glanced at the cave that Du Xu said, and then spoke directly without thinking about it: "Open it!"

Du Xu took out the disc and fiddled in front of the cave.

Xiang Yun could see that the disc seemed to contain the formation, which corresponded to the formation in the cave, and could open and close the formation.

Xiang Yun noticed this detail and couldn't help but glance at Du Xu more.

This kid said that it was his master who sacrificed himself to save others, threw him out of the cave, and closed the formation, but if this was the case, why was the disc that controlled the formation in his hands?

If this kid was really so sad and wanted to go in and save the master, wouldn't he just open the formation in the first place? He obviously escaped with the disc that controlled the formation, and even the formation was closed by him himself.

So the story he tells must have undergone a lot of polishing.
