In the dark canyon, the soul of the ghost control beauty was completely wrapped in the dark green flames of the poisonous demon, and let out a terrible scream.

The poisonous demon completely refined the soul of the ghost master, and the soul of the ghost king for hundreds of millions of years was also devoured by the poisonous demon.

For a moment, Yi Yun felt that the power of the poison demon was rapidly expanding, and its body became more condensed, as if it were an entity.

The poison demon has been born for hundreds of millions of years, such a long time, its growth is extremely slow, it has never experienced such a leap in strength, and absorbing the majestic power brought by the ghost king for hundreds of millions of years, making the poison demon's whole body feel comfortable, it can't help but look intoxicated.

"Hahaha, what a powerful force!"

The poison demon laughed, and it suddenly found that although he was forced to sign a soul contract, it seemed that following Yi Yun was also a good choice, if it was just him, it would be difficult to get such a chance to make a leap in strength.

"The rest of the people have swallowed it too!"

Yi Yun opened his mouth and said, at this time, there are only three people left in the Danxin Sect, the most powerful black-faced middle-aged man and Su Boyang, who have been abolished by the old snake and have no power to resist, not to mention the remaining Su Muyan.

"Thank you, Master!"

Hearing Yi Yun's order, the poison demon laughed wildly, this was simply a big meal for it, and it immediately split its body into three, turned into three green flames, and flew towards the three of them.

"Little brute, Dan Xin Sect will definitely cramp your skin!"

Su Boyang let out a crazy curse, but his resentful voice was quickly extinguished in the green flames, and then turned into a terrible scream.

"You...... You shall not ...... Good death!"

Su Boyang's voice was distorted, but he was still screaming.

"Old Piff, since you can call it like this, Lao Tzu will let you call it for a while. ”

The poison demon said with a smile, at this time, the souls of the three people are all in the hands of the poison demon, and he can torture as much as he likes, if these people just die honestly, it will be directly refined.

And like Su Boyang, if he wants to say some cruel things when he is dying, he will "entertain" him and make the other party die more painfully.

And the pain from the soul is many times stronger than a thousand cuts.

Soon, Su Boyang completely collapsed, and his consciousness was scattered by this pain, let alone continue to shout.

"What did you find?" Yi Yun asked.

"Back to the master's words, are some remaining memory fragments, incomplete, what the master wants to know, I will find and verify for the master. ”

These soul fragments are all messy, they are just sealed by the poison demon, and if you want to read and digest them, it will not be done in a while.

"I want to know the source of the Danxin Sect's inheritance, the core formation of the Medicine God Ding, and a medicinal herb called 'Withered Grass'. ”

Yi Yun opened his mouth and asked, these questions were what he was most concerned about, especially this "not withered grass", Yi Yun was very interested.

According to the direction given by Yi Yun, the poison demon searched carefully, and soon informed Yi Yun of all the results, because of the existence of the soul contract, the poison demon only needs one thought, he can share this information with Yi Yun.

It's just that the memories obtained from the soul search are too fragmentary, and it is impossible to get the complete inheritance of them, Yi Yun can only confirm that the inheritance of the Danxin Sect originally came from the relics left by the Medicine God in Guiru.

However, the Danxin Sect does not completely rely on the inheritance of the God of Medicine, in the tens of millions of years of the development of the Danxin Sect, they have obtained more and more inheritances, some of which are ancient, and even make up for the shortcomings in some of the Medicine God classics.

For example, the cultivation of "non-dead grass"!

At the beginning, the god of medicine did not study "non-withered grass" in too much detail, but only believed that this medicine was extremely rare and difficult to grow artificially.

However, Danxin Sect found a way to refine the "Rejuvenation Pill" on a large scale, but unfortunately, Danxin Sect's Dan recipe had serious defects, so that it did not make full use of the "non-withered grass".

In addition, Dan Xinzong has also collected some classics that record the core array of the Medicine God Ding over the years, and even obtained the fragments of the formation of the Medicine God Ding, if Yi Yun can get these classics and fragments, he may even repair the Medicine God Ding.

"This Danxin Sect has really mastered a lot of ancient inheritances, if I can get the inheritance of the Danxin Sect and make up for some of the deficiencies in the Medicine God Classics, I can make my Dan Technique go further. ”

Yi Yun muttered to himself and glanced at the old snake inadvertently.

And this glance made the old snake extremely vigilant.

"Boy, what do you see me doing? Wouldn't you fall in love with something from Dan Xin Sect and want Lao Tzu to be your thug? I warn you not to think about good things, although Lao Tzu killed a few elders of Dan Xin Sect, but who knows what the most powerful old monster behind Dan Xin Sect is, even if he can't beat me, I don't want to make a move, fighting with him is bound to waste Lao Tzu's life, you kid don't want to hit Lao Tzu with your idea. ”

The old snake hurriedly made his attitude to Yi Yun, he has always been the master of not seeing rabbits and not scattering eagles.

Yi Yun touched his chin and said slowly: "Didn't you just listen to me ask about not withering grass? It is a life-prolonging elixir, if you can get a large amount of non-withering grass, I can refine this life-prolonging pill on a large scale, I wanted to give you one hundred and eighty pills, but it seems that you are not interested in it......

"What?Longevity Pill!?"

The old snake's eyes widened, if there was anything in this world that attracted the old snake the most, it must be a way to prolong life and repair the foundation.

And usually, the two are the same thing for the old snake.

"Is there such a thing? Can it be refined on a large scale? Don't lie to me!"

The old snake knew that all the elixirs that involved prolonging life and repairing the foundation were very expensive, because of the limitations of material problems, making large-scale refining almost impossible.

Yi Yun said: "'Large-scale' is also relative, even if there is 'no dry grass', the cost of refining is very high, and this kind of longevity pill is eaten at the beginning of the effect, and the later the effect is, the smaller the effect." ”

Yi Yun said truthfully, any pill will become worse and worse if you keep taking it, which is not a problem for the old snake at all.

The old snake clapped his hands, "Boy, tell me, what are you going to let me do." ”

Listening to the old snake's words, Yi Yun rolled his eyes, this old man is too direct.

"Pack up the corpse first, let's go back to the city!"

He had just killed so many people from the Danxin Sect, and Yi Yun didn't want to stay here for a long time, lest the Danxin Sect have people who supported him, and then there would be trouble.

"Good. ”

The old snake immediately released a few fireballs, burning all the corpses into ashes, and then the wind blew, all the ashes disappeared, and there was not even a trace of blood left, as for the traces of the battle, it was completely wiped out by his random fist wind, it seems that the old snake is already familiar with this thing of cleaning up the battlefield.

"Let's go, go back to the city. ”
