When the centipede essence was cut in half and struggled in pain, Luo Zheng raised the spear formed by the condensation of corpse qi and stabbed into the head of the centipede essence.

A lot of green smoke floated out of the centipede's corpse.

The green smoke faintly converged into a humanoid silhouette, but it didn't take long for it to dissipate, and it was unable to pose any threat to the person.

Xiang Yun stared at the disappearing green smoke, revealing a thoughtful expression.

Lan Xiang breathed a sigh of relief, retreated to Xiang Yun's side and said, "Teacher, it's done." ”

"The centipede spirit's inner dan is in the seventh carapace of the upper body. Xiang Yun gave Luo Zheng a look, "Go and take it out." ”

Luo Zheng immediately opened this thick and sturdy carapace, reached in and took it out for a while, the palm of his hand was quickly corroded by poisonous blood, and when it was stretched out again, only the outline of a metacarpal bone remained.

It hurts to watch.

However, the Corpse King felt no pain.

A small emerald green bead was pulled out.

This is the inner dan of the mutant centipede spirit, and it is a rare thing.

The treasure trove of Western Chu University is very rich in materials, and the materials of the seventh and eighth level demon beasts may be very rare in the outside world, and they can only be found in high-end auctions, but a lot of inventory can be easily found in Western Chu University.

However, even in Xichu University, the high-grade materials in the inventory are mainly conventional materials, and if you want to use some special models, you have to look at the character.

Now this Nedan belongs to this material.

The poison of the high-level poison attribute demon beast has long been out of the material level, but an energy toxin, which is directly contained in the yuan force, which is why it is so powerful.

The Demon Beast Neidan is the source of a Demon Beast's Yuan Force.

The Poison Attribute Demon Beast Neidan must be a powerful poison reservoir and poison source.

But with the death of the demon beast, the Yuan Force stops functioning and gradually solidifies, and the energy toxin will quickly dissipate, which means that the shelf life of the poisonous attribute demon beast Neidan is very low.

There are not many pure poison attribute demon beasts in the first place.

The shelf life of the inner Dan is generally three or four days.

It is inconvenient to store, inconvenient to transport, and dangerous to transport, so there are few stocks of poison pills, and it has naturally become a rare thing.

The most important point is that there are not many uses for the poison attribute inner pill, and few people will take the risk of collecting this kind of thing, so there is no reserve in Xichu University, but this kind of thing is a pure natural elixir for people like Jiang Xiaonan who practice poison skills.

Xiang Yun ordered Luo Zheng to cut off the venom glands of the centipede essence and put them up.

This centipede essence is not an ordinary centipede essence, but a super centipede essence that has been specially cultivated and mutated.

Therefore, its venom glands also store powerful energy, of course, the rate of loss is very fast, and it must be used as soon as possible.

The other body parts of the centipede essence are also valuable materials, especially the carapace of the centipede essence, which is not only as strong as a black iron knife and invulnerable, but also has a super anti-poison and anti-corrosion ability, and was taken away by Luo Zheng casually.

The mission for this trip has been completed.

It was surprisingly smooth.

This is thanks to Arashika's help.

Without her connections and assistance, how easy would it be to find a poison that meets the requirements from Wuzhou County? Xiang Yun looked at Du Xu next to him, "The centipede essence has been removed, and your teacher can rest in peace." ”

"Thank you, Mr. Yao, thank you Miss Lanxiang, I think my teacher will be very pleased if he knows the old man. Du Xu's expression changed slightly, and then a sad look appeared, "I'm going to set up an altar here to pay tribute to the teacher, I'm afraid I won't be able to return with a few of them." ”

"There are some areas that cannot be mastered by mortals, and I hope you will not repeat the mistakes of the past. ”

Xiang Yun uttered such unfathomable words.

Du Xu's expression obviously became a little unnatural.

But Mr. Yao didn't seem to have done anything superfluous, and when he achieved his goal, Mr. Yao left with Lan Xiang and his attendants.

Du Xu stayed alone in the cave, his expression a little cloudy.

Eventually, he opened a mechanism in the cave and entered a secret chamber.

The small space in this chamber was apparently a place to store materials, with a large number of ancient scrolls and notes, as well as strange instruments.

After Du Xu saw these materials, the handsome sunny face gradually showed a crazy look, from now on these things are all his!

The knowledge contained in this is enough to drive people crazy!

Xiang Yun and Lan Xiang walked on the way back.

Arashika seemed to stop talking.

Xiang Yun said in a pretending indifferent tone: "You can ask whatever you want." ”

"Du Xu has a problem, the story he made up has a lot of loopholes, and judging from the way he looked just now, this kid is hiding other motives, and it is not for the so-called revenge at all. Lan Xiang obviously noticed the problem a long time ago, "Did the teacher also see something? Master Du Xu's death, could it be that he did it himself?"

Xiang Yun was noncommittal on this question: "You are a demon, you should know that it is not easy for a demon to become a spirit." ”

This is also one of the places where Lan Xiang suspects Du Xu.

"If the demon wants to become a spirit, it must either have an adventure under some kind of opportunity and be selected, or it will produce spirituality little by little over a long period of time and finally give birth to spiritual intelligence, and there are no necessary conditions for becoming a spirit in the cave...... But this centipede demon has indeed become a spirit. ”

"I saw a broken soul in the centipede spirit. Xiang Yun paused for a moment, "This centipede should be Du Xu's teacher, so he didn't come to avenge his teacher, but to kill his teacher." ”

"Huh, how can this be!"

"The cave is clearly not a place to cultivate materials, but a place to cultivate containers for secret experiments. Xiang Yun said lightly, "If I'm not mistaken, they found a way to transfer souls, so they conducted soul transfer experiments, and the centipede essence was the product of this experiment, but it was not very successful from the results." ”

Arashika was shocked by such a statement.

What Mr. Yao means is that the reason why the centipede demon beast can become a spirit is because Du Xu's master forcibly stuffed his soul into this body, so the centipede demon beast mutated, not only growing a human face, but also possessing spiritual intelligence.

"This is too crazy, but why do you want to become a demon if you are good?" Lan Xiang didn't understand this question, "We demons are desperately trying to form humans so that they can practice more exercises, and good people, why should they let themselves merge with demons?"

"Lifespan, strength, and these two reasons alone are enough to explain your confusion. Although the demon body has many inconveniences, it generally has a longer lifespan than humans, and it is not surprising that if a person is about to reach the end of his life, even if he does something crazy. ”

It's the first time Arashika has encountered this kind of thing.

If that's the case, there's a surprising secret hidden in it!

What happened back then? Was the experiment a failure, or did Du Xu frame his teacher, or something else caused all this.

Lan Xiang asked curiously: "Teacher, since you have already seen everything, why didn't you just let Xiang'er kill this Du Xu and directly take this technique over and study it yourself?"

A demon is a demon.

At every turn, you will kill people and seize treasures.

If it weren't for Xiang Yun standing here at this time, it is estimated that Lan Xiang would definitely sneak back and solve Du Xu, after all, soul transfer is such an awesome technique, just thinking about it makes people feel excited.

"Hmph, if this technology was really useful, I wouldn't have created such a monster. Xiang Yun was dismissive of this.

Damage and memory loss that will definitely result from soul transfer.

In addition, the side effects of the residual fusion of human souls and demon souls, and entering a deformed container are like a hardware device, and various driver conflicts are lost, which can lead to big problems.

Xiang Yun has enough to study.

He wasn't interested in learning about these side-of-the-road techniques.

Du Xu's guy is obviously not a good thing, I don't know if he will conduct such an experiment again in the future, but since he helped himself, crossing the river and demolishing the bridge is not Xiang Yun's character.

Let him go.

Anyway, the advice has been given.

If Du Xu still wants to die, then no one is to blame.

Lan Xiang thought that Mr. Yao's superior demeanor disdained to do it to juniors, and at the same time disdained this kind of side-to-side insect carving skills, although she was very interested in this technique, but in front of Mr. Yao, she just pressed down.

"You're helping me a lot this time, and I can't let you do it in vain, what kind of reward do you want?"

Xiang Yun thought that he was now a teacher.

His disciple has worked hard for a while before and after the saddle, and he has to give a little reward anyway, I hope that this guy Lan Xiang will not open his mouth loudly, and Xiang Yun is not very rich now.

Lan Xiang had been waiting for this sentence for a long time.

She felt her heart pound.

However, Lan Xiang still suppressed her impulse and pretended to say: "It is Xiang'er's honor to do things for the teacher, and Xiang'er does not dare to ask the teacher for payment." ”

"I don't owe a favor to someone. Xiang Yun guessed that he would get such a pretended answer, so he also pretended to take out a jade slip, "I didn't bring anything valuable with me, and this work was created by me recently, and it has universal value, so it should be very useful to you, so I'll give it to you." ”

"Huh, what's so embarrassing!"

The mouth says no, but the body is very honest.

Lan Xiang took this jade slip and couldn't wait to open it, and the first line was written with the name of this work "Aoki Changchun Gong"!

Is Aoki Changchun Gong a medicine technique?

Lan Xiang glanced at the general outline, and she was almost frightened.

It is not a medicine practice, nor is it a medicine practice, but it is compatible with both schools.

Medicine in one!

Medicine in one!

This is an original practice of medicine and medicine!

The relationship between doctors and pharmacists, for hundreds of years, many bigwigs have tried to develop the practice of medicine integration, although there are many works and papers, but they are all facing such and such problems.

Now, however, this problem has been overcome!

The person who conquered it was Mr. Yao, and no one in the whole of China knew about it!

Lan Xiang could see that the exercises themselves were not advanced, and even biased towards the entry-level level, but the huge significance it represented could shake Huaxia!

Mr. Yao actually gave such an exercise to himself?

That's a little too exciting, isn't it?

Lan Xiang suspects that she didn't wake up!

She now feels as if she helped an old grandmother cross the street, but in order to thank her, the old grandmother casually gave her several large pieces of oil fields worth tens of billions.
