After taking out the white vial, Lin Yuan opened the cap of the bottle and released a green light cluster.

This green light cluster is the soul of the vulture in the foundation building period.

"Gah!"

As soon as the green light cluster came out, a mini vulture phantom appeared inside, watching Lin Yuan let out a frightened scream, and then turned into a green light, wanting to escape from this place.

"Hmph, evil beast, you still want to run in front of this king?" Lin Yuan snorted coldly, and then with a wave of his big hand, he condensed an illusory big hand composed of spiritual energy in mid-air, and grabbed the soul of the vulture in the foundation building period.

"Quack, quack......"

The spirit of the vulture in the foundation building period struggled desperately, and kept shouting, you stupid cow, let go of this seat.

"Let you go, what about dreaming?" Lin Yuan smiled disdainfully, "Tell this king, are there any stronger demon beasts in this mountain range?"

"I don't know!" said the vulture indifferently.

"Don't say it, that's good, this king can also get the information you want by searching for your soul!" Lin Yuan smiled coldly.

The so-called soul search is to search for the memory information in the soul.

This is a secret technique that Lin Yuan found from the memories of the black people in the foundation building period.

Generally speaking, if you want to perform the soul searching technique, your own soul power must be stronger than the opponent's.

Of course, if the other party is willing to take the initiative to cooperate, then soul searching will be much easier.

However, if the other party refuses to cooperate and forcibly searches for their souls, it will cause serious damage to their souls, or even directly collapse their souls.

Lin Yuan's divine soul power far surpassed that of people of the same level, and he could completely forcibly search the soul of the vulture in the foundation building period, and then obtain the memory information he wanted to know.

As for why Lin Yuan didn't devour the soul of this vulture in the foundation building period like he did before, it was because devouring the soul of the god soul of the other party was not only the memory of the other party, but also some bad things, and if he devoured more, it would cause irreversible serious damage to himself.

Before devouring the soul of the black man in the foundation building period, Lin Yuan had sensed some adverse effects, and he had not completely cleared it up until now, so he naturally did not dare to continue devouring other divine souls.

"Soul searching, you actually know the evil witchcraft of humans?" the vulture spirit of the foundation building period immediately exclaimed, it seemed that it had also heard of the soul searching technique, and knew the power of this secret technique.

"Are you afraid, if you're afraid, just tell the truth!" Lin Yuan smiled coldly.

Forcibly casting the Soul Searching Technique would consume a large amount of his own Divine Soul Power, so if he didn't use the Soul Searching Technique, he would be able to get the information he wanted, and Lin Yuan naturally didn't want to use the Soul Searching Technique easily.

"But I really don't know!" said the vulture spirit of the foundation building period with a bitter face.

"With your cultivation during the foundation building period, I'm afraid you'd have already flown to the entire mountain range, right?

"King Niu, I really don't know, I'm not a demon beast in this mountain range, I'm from outside!" the vulture in the foundation building period hurriedly explained.

"Oh, from outside, what are you doing here?" Lin Yuan was slightly stunned, and then asked curiously.

"I'm here to find the Valley of Ten Thousand Demons!" replied the foundation vulture immediately.

"Ten Thousand Demon Valley, what is that?" Lin Yuan's eyes lit up, and he hurriedly asked.

"It is rumored from the outside world that in this mountain range, there seems to be a mysterious valley called the Valley of Ten Thousand Demons, and there are many powerful demon clans gathered in the valley, and they have established a free fang city there, and many big demons around it will often go to the Valley of Ten Thousand Demons to trade with the demons in exchange for the cultivation resources they need, I also want to try my luck, but I didn't expect that before I found the Valley of Ten Thousand Demons, I met the king......" The vulture hurriedly explained, and said in the end, it looked very depressed, it can be regarded as dying before leaving the school.

"There is still such a place...... Lin Yuan's eyes flashed thoughtfully, and then, he looked at the vulture in the foundation building period with a cold smile and said, "You miscellaneous bird, it seems that you are still very aggrieved? If you don't have a bad plot and want to take advantage of this king's breakthrough in the foundation building period, you will be killed by this king in the end? Hmph! After killing so many people from this king, what do you say this king should do with you?"

"The king spares my life!, it's me who has eyes and doesn't know Mount Tai, it's me who deserves to die, I only have a soul left, please spare my life!" the vulture hurriedly begged during the foundation building period.

"Spare you, dreaming, you better go back to the bottle and think about what this king will do with you!" Lin Yuan smiled coldly, and as he spoke, he stuffed the soul of the vulture in the foundation building period into the white vial again.

When he was questioned just now, Lin Yuan had been carefully sensing the fluctuations of the vulture's soul in the foundation building period, and finally confirmed that the other party was not lying.

In other words, this vulture is indeed from outside.

And in this mountain range, there is indeed a possibility that there is a Valley of Ten Thousand Demons!

It's just that the vulture doesn't know the location of the Valley of Ten Thousand Demons.

Now, this vulture's divine soul is of little use to Lin Yuan, but Lin Yuan will not destroy it immediately, let alone let it go, because in the immortal cultivation world, the divine soul is also a very important resource, which can do many things, stay on the body, and it will definitely be useful in the future.

After putting away the vulture's divine soul, Lin Yuan began to think about refining the elixir.

Now, he has advanced to the foundation building period, and if he wants to improve his cultivation as soon as possible, he must refine a batch of Juyuan Dan.

However, Juyuan Dan, a second-grade elixir, seems to be difficult to refine, not only requiring a lot of precious second-grade medicinal materials, but also superb alchemy attainments.

As a result, in the space ring of the black people in the foundation building period, there were only three Juyuan Dan.

In terms of medicinal materials, Lin Yuan already had several main medicinal materials for refining Juyuan Dan, but he still lacked some auxiliary medicinal materials, and he still had to find a way to collect some more.

As for the alchemy attainment, Lin Yuan still lacked a lot.

After all, you must know that he has not even refined a real first-grade pill now, let alone refined a second-grade pill.

In other words, the matter of alchemy, I'm afraid it still has to be considered in the long run, and we can't rush it for a while.

In contrast, the matter of refining is a little easier to handle.

At least, Lin Yuan had all the materials for refining low-grade spiritual weapons and middle-grade spiritual weapons.

Moreover, he had also refined a large number of spiritual weapons before, so he did not lack much in terms of refining techniques.

The reason why he failed to refine the real spirit weapon was mainly because there was a necessary thing missing from the spirit weapon he refined, that is, the formation rune!
