"Oh, are you sure?"

When Beiming heard Du Wenxing say that he wanted to try it, he was immediately very interested, and the doubts hidden in his heart deepened!

He knew that Du Wenxing had never come into contact with the Immortal Cultivation Method, and the exercises obtained by the Jiuyang Immortal Mansion had never been opened to cultivate, except for that time in order to open the space ring, it was also a shallow taste.

So, why did he "try"?

Beiming knew that Du Wenxing, this kid was not a big talker.

This kid is definitely hiding a big secret.

Du Wenxing walked around the arrangement of the black spots, silently calculating in his heart, and his fingers pinched quickly.

Half an hour passed......

Du Wenxing still didn't make a move.

Beiming became a little impatient, and began to doubt what he had just thought.

Is this kid okay?

At this moment, Du Wenxing suddenly jumped high, his claws slashed left and right, and two true yuan struck, and the true yuan was also wrapped in the aura mobilized from this silk mixed yuan bead.

Boom!

A cloud of black liquid emerged from each of the black ground.

Du Wenxing's hands were linked, and one after another the true elements wrapped in spiritual energy were shot, and eighteen balls of black liquid appeared one by one.

Beiming is greedy, these auras are really pure, I haven't eaten this delicious taste for a long time!

Black threads stretched out of the black liquor, intertwined with each other.

Then a black vortex suddenly appeared.

Du Wenxing's eyes lit up.

It's done!

The next moment.

He moved, and threw himself into the black vortex.

The outlook changed abruptly.

I have come to a "cave house".

After stabilizing his mind a little, Du Wenxing walked in it.

As you walk, you look around at your surroundings.

It is not as desolate and dark as a tomb as imagined for thousands of years, but as bright and warm as a spring wilderness.

Nearby, the waterfall and flowing spring, the cicada noise forest is quiet; in the distance, the mountains are steep, the birds are singing and the mountains are secluded; below, the green grass is knee-high, walking in it, the sound of brushing is pleasant; above, the soft light is dazzling, bathing in it, warm and comfortable to sleep.

There is also a gentle breeze, bringing waves to the grass field, rippling countless situations.

All this, if it falls into the eyes of mortals, you should think that you are in a fairyland, and you will not be happy.

But for people like Du Wenxing who have experienced the world of Xianxia, everything in front of him is false.

The waterfalls and springs are fake, the mountains and mountains are fake, and the cicadas and birds are illusory...... Only the grass under your feet and the light above your head are real!

"It's all fake, a devil, what are you doing to make your own residence so fairy!" muttered Beiming.

In fact, if it was thousands of years ago, such a scene would definitely not be able to be seen through by Du Wenxing's level of vision, but thousands of years of wind and frost could have already made everything lose its former brilliance.

It has been running continuously for thousands of years, without maintenance or repair, and it can still maintain its current level, which can already be seen in the prosperity of this demon mansion back then.

In Du Wenxing's powerful spiritual power induction, after this cave house is removed from the fake and the true, only these knee-high grass under his feet are genuine, even if the light above his head is debatable.

If there is no light, how can the grass be green and vibrant in such an environment?

As far as the eye can see, it can be seen that the top of the head is full of snow-white light like day, but these lights are not illuminated by the sun, but are dotted with pure white crystal clear crystals the size of fists.

"Obsidian!"

Bei Ming let out a cry of surprise.

"What is this?" Du Wenxing asked if he didn't understand.

"Sunstone is a kind of spirit stone, which contains the power of the sun, and it was a sought-after item in ancient times. If the cultivators in the ancient period had cherished the spiritual grass, most of them were cultivated in the caves, and things like spiritual springs were just that, it was not a big deal, but the light that they didn't usually care about became a big problem at this time. Not to mention adjusting to the level that is suitable for the growth environment of the spirit grass, just by introducing light into the cave, there are many problems that are difficult to solve. ”

"The easiest way is to open the skylight to attract light, more to open a big opening, less to penetrate a few gaps, so that the effect is good or not, not to mention, safety alone, it is not easy to solve. ”

"Light can enter, but other things can't enter? Daylight can enter, but other rays can't enter? Doesn't it mean opening the door to steal!"

"At this time, obsidian plays an irreplaceable role. ”

Bei Ming explained: "The biggest feature of this spar is that after it is stimulated, it can emit a light that is no different from ordinary sunlight, and after being restricted by a special magic circle, its strength can be adjusted arbitrarily, which is really an indispensable good thing for cultivating elixirs. ”

"Quack, huh?" Du Wenxing was overjoyed, "Come, change your wings, quack, let me fly." ”

When Bei Ming heard this, he hurriedly said: "Then you have to settle the accounts well, these obsidian stones will divide half of me." ”

Du Wenxing thought for a while, "Okay, quack!"

Two black wings extended from under Du Wenxing's ribs.

Poof, poof!

Flapping his wings, Du Wenxing flew up, and after a while, he came to the top of the cave.

Looking at the dense and uncountable obsidian stones above his head, Du Wenxing swallowed his saliva, this is too much!

In other words, with so many obsidian stones, where should I put them?

Bei Ming seemed to guess his thoughts, and proposed: "If you practice that Jiuyang True Sutra again, there is a lot more spiritual energy left in this cave than in the outer world, which can maintain your consumption, and you don't have to waste your own stored spiritual energy." ”

That's a good idea.

Du Wenxing nodded.

"Quack, Beiming, you help me fix it. ”

"Small meaning. ”

The black wings that kept flapping suddenly turned upwards and turned into four black suction cups, which were tightly attached to the top of the cave, hanging Du Wenxing in mid-air.

Du Wenxing closed his eyes and concentrated, and started the Jiuyang True Scripture.

With the previous successful experience, Du Wenxing got started extremely fast this time, and after an hour, he opened his brilliant eyes.

"Hurry, hurry, quack, my mental strength won't last long. ”

The Northern Darkness instantly turned into countless tentacles and shot towards the obsidian stones in all directions.

After removing more than a hundred obsidian stones, Du Wenxing stopped.

It suddenly occurred to him that the capacity of his spatial ring was limited, and this obsidian sounded from the mouth of the Northern Underworld, and it seemed that it was not a top-level item in ancient times, otherwise it would not have been used for such purposes.

If the capacity of the space ring is full at this time, there are other more valuable treasures in this cave, where to put them.

Anyway, the obsidian is here, if you search the entire cave, there is still room for the ring, and you can come back and get it again.

After listening to Du Wenxing's thoughts, Bei Ming felt that it made sense, "You're right, although obsidian is a good thing, it wasn't impossible to buy back then, and the price was not enough to make ordinary monks crazy about it." At this time, what is really important is the treasure in this cave, thinking that the demon lord has made such a big exercise with a small greenery, the value of the real treasure can be imagined. ”

So I also stopped, and only swept a dozen or so pieces wrapped in my body and ate them as snacks.
