The answer is yes.

Beneath the shattered and collapsed mountain, there was definitely something for the Black Bone Beast to protect.

And something that can be guarded by an undead beast comparable to the early stage of the Xuanhe Realm...... How good value would it be?

"Roar!!"

Lu Lan's thoughts turned around as quickly as lightning, and he saw that the black bone beast roared angrily, got up from the ground and rushed towards Lu Lan again!

There is an advantage in the face of this kind of undead beast controlled by death qi, that is, the other party will forget what kind of ability he controlled before his death, and although his physique has been terrifyingly enhanced after becoming an undead beast, he can only use this pair of meat...... No, use this skeleton to attack the enemy.

Therefore, it has a very simple way of attacking...... Can only go on a rampage.

Although Lu Lan's physique is not much different from that of the same realm cultivator who refines his body, he can't force the black bone beast's collision attack every time, otherwise his internal organs will be knocked to pieces.

Putting away the Baxuan Giant Sword, Lu Lan's movement speed suddenly increased a lot, and coupled with the [Wind and Thunder Shadowless Step], he easily dodged this attack from the Black Bone Death Beast.

Then, before the Black Bone Death Beast could react, it rushed directly in the direction of the collapsed and broken mountain!

"Roar!!"

The roar of the Black Bone Undead Beast suddenly became urgent, obviously discovering that Lu Lan wanted to break into its guarded place.

However, it was too late to stop it.

Lu Lan came to the place where the collapsed rubble was, and found that there was a huge crater in front of him!

And from the periphery of the pothole, a strange aura was clearly heard.

Lu Lan found that this breath seemed to be somewhat familiar...... But for a moment he couldn't remember where that familiarity came from.

"No matter, let's go down first."

Lu Lan didn't feel any dangerous aura below for the time being, and there was a black bone beast behind him, so he didn't think much about it, and jumped down directly.

During the fall, there was darkness around him, and Lu Lan always used the [Candle Dragon Pupil] to watch out for everything around him.

Suddenly, he saw a light purple light gradually appear below.

"That's ...... Xuanyuan amethyst? ”

Lu Lan's eyes shook slightly.

Xuanyuan amethyst is the product produced after mining the Xuanyuan crystal vein.

It is richer and purer than the qi contained in ordinary Xuanshi.

Therefore, in some high-level transactions, both parties will not trade with Xuanshi, but use higher-grade Xuanyuan Amethyst for trading.

One Xuanyuan amethyst is equivalent to a hundred Xuanyuan.

And before Lu Lan landed, he could already feel the lilac light in front of him getting more and more intense.

It is conceivable how much Xuanyuan Amethyst is hidden underneath!

Bang!

Lu Lan successfully landed safely.

As he expected, there were Xuanyuan amethysts all over the ground, even on the surrounding rock walls.

"What the hell is this place...... In a secret realm, there are so many Xuanyuan amethyst? ”

Lu Lan was a little shocked.

At this time, the roar of the black bone beast was still heard above, and it became clearer and clearer, obviously it was about to come here.

Lu Lan glanced to the left, where there was obviously a passage.

He immediately withdrew his breath and quickly headed in that direction.

A moment later, the black-bone undead beast slammed to the ground.

However, after landing, it closed its mouth and stopped roaring, only the pair of gray-black pupils were still scanning the surroundings, trying to find Lu Lan's traces.

At the same time, it moves as lightly as possible, trying not to make any sound...... It's not like it's to catch Lu Lan, it's more like it's to not disturb some existence here.

And Lu Lan's side, after passing through such a passage, his eyes suddenly opened up.

He didn't expect that under the ground of this ancient medicine fairyland, there would be such a wide cave chamber!

Around the cave, there are quite a lot of Xuanyuan amethysts stored, and they can almost turn into a small mountain when they are piled up.

Therefore, the Xuan Qi that was permeated here was even more refined and rich than the Xuan Qi that Lu Lan felt in the Medicine God Sect outside.

"Huh? That's ......"

Lu Lan suddenly noticed that there seemed to be something different in the center of the cave.

"Roar!!"

A deliberately suppressed dull roar came, and Lu Lan turned his head to look at it, and found that the Black Bone Death Beast had already spotted his figure and was speeding towards this side.

Lu Lan didn't notice that it was still deliberately controlling the movement, and directly turned around and rushed towards the center of the cave.

When he got closer, Lu Lan realized that it was a dry mound.

In front of the mound stands a rather ordinary-looking stone monument.

It's just that there are three diamond-shaped holes on this stele, obviously to find the corresponding thing and put it in.

"This ...... Isn't it just about finding the corresponding shape of Xuanyuan Amethyst and then putting them in? ”

Time is pressing, and Lu Lan can only think of this way.

"Roar!!"

The Black Bone Undead Beast also entered the cavern.

Only the passage in this cave leads to the outside, and now that the Black Bone Undead Beast appears there, it is equivalent to blocking the only exit.

Lu Lan had no other way out than to stay next to this dry mound.

However, Lu Lan soon discovered something more peculiar......

After the black bone beast found out that he was staying next to the dry mound, it didn't let out any more roars, nor did it dare to approach, but slowly walked around, its gray-black pupils staring at him, as if looking for an opportunity to attack him.

Other words...... It was afraid that it would accidentally destroy this dry mound in order to attack Lu Lan, so it didn't dare to approach.

"It seems that the one buried under this mound is probably its former owner......"

Lu Lan couldn't judge the identity of this black-bone beast for a while, and he couldn't tell what period it died in.

If the Black Bone Beast hadn't been covered in bones like it was now, but had retained a bit of its characteristics, Lu Lan would have been able to deduce who the person buried under this dry mound was through its identity.

"In short, while he hasn't attacked me yet, hurry up and find those three Xuanyuan Amethysts that match the shape."

Lu Lan quickly made a decision.

To find three Xuanyuan amethysts that match the shape on the stone tablet are like a hill around this mountain, which is tantamount to "looking for a needle in a haystack".

And in the current situation, the only means that can be used is to use soul power to take it.

This is similar to how he had used his soul power to probe and compete for the medicinal materials in the ring.

But this situation is much more difficult and dangerous than that of the Medicine God Conference.

Lu Lan needs to separate a part of the soul power for investigation, and at the same time, he also needs to keep a part of the soul power to keep an eye on the black bone beast at all times, in case it suddenly ignores and directly attacks him.

Fortunately, this black bone beast seemed to attach great importance to this dry mound, even if Lu Lan sat motionless next to the dry mound for nearly a quarter of an hour or so, it never attacked Lu Lan.

Lu Lan's soul power was already quite strong, and winning the Medicine God Conference was enough to prove it.

However, even so, it took nearly half a column of incense to find the first Xuanyuan amethyst that matched the shape of the stone stele.

This is also quite a drain on soul power.

"No wonder only alchemists are allowed in...... Only an alchemist could possess such a powerful soul power. At the same time, strong people with too high cultivation are not allowed to enter...... Otherwise, this guy wouldn't be able to protect this place. ”

While Lu Lan continued to use his soul power to search, he finally figured out why there were such strict restrictions on entering the Ancient Medicine Immortal Realm.

Nearly half an hour later.

Lu Lan finally found the remaining two Xuanyuan amethysts that matched the shape.

And the outrageous thing is that the black bone beast is still staring at him in circles...... It seems that even if you become an undead beast after you die, you can still act, and you don't have a certain ability to think.

Otherwise, there should be some other action at this point.

In short, Lu Lan was not worried that this black bone beast would suddenly attack him.

He put the remaining two pieces of Xuanyuan Amethyst into the hole of the stone tablet in turn.

Suddenly, the stele suddenly began a high-frequency vibration, shattering all the dust and stones on the surface.

Lu Lan immediately got up, watching out for the black bone beast while staring at the changes in this stone stele.

When the shock stopped, Lu Lan realized that this was an ordinary stone tablet...... It is clearly a "Xuanying Monument"!

And it is also a long-ago Xuanying Monument.

Lu Lan sensed that there was a very special Xuan Array here, and if he didn't find three Xuanyuan Amethyst with the same shape, he wouldn't be able to trigger this Xuan Array.

Soon, the Shadow Tablet projected a slightly illusory figure.

As soon as the "human figure" appeared, the black bone beast seemed to have seen its owner, and suddenly stopped, and its gaze shifted from Lu Lan to the "human figure".

"Huh? Who started this Shadow Monument? ”

The "figure" turned his head and saw Lu Lan on the side.

"Junior Lu Lan...... I don't know the name of my predecessor? ”

Lu Lan first saluted, and then quietly observed the other party's reaction.

Lu Lan ...... Ten thousand years have passed, can such an outstanding alchemist still appear in the current Cangyuan Continent? ”

The "Figure" first sighed appreciatively, and then spoke:

"As for me, I've forgotten my name for a long time...... However, 10,000 years ago, those bastards called me 'Ancient Medicine Venerable', and they tried to kill me many times, but they never succeeded......"

"You can just call me 'ancient medicine'."

10,000 years ago!

Ancient Medicine Venerable!

Only then did Lu Lan remember where her inexplicable familiarity came from.

Dare to love this ancient medicine fairyland...... There is even the bones of a continent powerhouse buried 10,000 years ago!

Wait, does that mean...... This secret realm was actually created by this "Ancient Medicine Venerable"?

"Huh? This breath of yours...... It's a lot of fun. ”

The Ancient Medicine Venerable glanced at him, and his eyes seemed to be a little meaningful.

Lu Lan couldn't understand this look a little, and just wanted to ask for an understanding, he heard the Ancient Medicine Venerable turn his words and say:

"Little one, what are you doing here?"

Lu Lan had no choice but to relay Yan Xuzhi's words.

When the Ancient Medicine Venerable heard that there seemed to be a change in this secret realm, his eyes suddenly changed, and he subconsciously blurted out:

"Could it be that the guy I sealed in the first place has woken up?!"
