From the foot of the hillside to the bottom of the courtyard wall, the distance of hundreds of meters, all piled up with dry bones, layer upon layer spread in every place around, in the moonlight under the miserable white glow, surrounding the courtyard wall to form a ring, giving people an indescribable sense of weirdness.

Some of the bones were clearly years old, while others looked very new, as if they had just died.

Su Lun and Yuru looked at each other, a little stunned for a while, not knowing what to do.

Su Lun's divine thoughts extended to the side of the courtyard wall, and he found that he could no longer enter, as if the courtyard wall had the ability to block visits.

"I'll go check it out first, you wait here. Yu Ruyi said that she was about to go down, but was pulled by Su Lun.

"Sister, I'll be scared outside, so I'll go in with you. He said that he was afraid, but there was no fear on his face, obviously he was just afraid that Yu Ruyi would be in danger and go with her.

Yu Ruyi wanted to say something, but Su Lun tightened her hand holding her arm and said, "Sister, you know what I think." ”

Yu Ruyi sighed lightly, didn't refuse again, and let Su Lun pull him over.

"Click-"

A continuous sound sounded, it was the sound of weathered bones being fragile and broken directly by the two of them.

"Sister, look at these bones, they are of different shapes and sizes, they should belong to many kinds of animals, I suspect that we can't see animals along the way, it should be because ...... They all died here. ”

"Iron Claw Jade Tiger, Big Winged Blood Eagle......" Yuru had more opinions, and even saw what kind of thing some bones belonged to.

But the more she spoke, the greater the surprise on her face, and in the end, she had a trace of horror, and muttered: "These beasts, all of them are earth or sky kings, and some are even beasts above the third order, how could they die here one after another?"

"What's so strange about this courtyard wall that it would attract them to die one after another?"

Su Lun naturally didn't know why, and the two of them walked carefully through the thick layer of bones, and they didn't know how many bones of powerful beasts they had broken along the way before they reached the side of the courtyard wall.

With so many powerful beasts all killed here, the two of them became even more vigilant.

At this moment, in front of the two of them is a huge door, not gold or wood, I don't know what kind of thing is cast, it is engraved with complicated patterns, and in the middle of the door is also engraved a huge skeletal face, the expression seems to be smiling but not smiling, extremely weird.

But at this moment, I don't know who opened a small crack in this door, and the two of them glanced into the crack, and it was foggy and they couldn't see anything clearly.

Su Lun shook his right hand as if he was cheering himself up, and then he remembered that his left hand had been holding Su Lun's arm all the time, and he was a little nervous just now, but he didn't care about it.

Feeling Yu Ruyi's smooth, tender skin, he was surprised that Yu Ruyi was caught all the way by him like this, and there was no reaction?

After glancing at Yu Ruyi, she could only see her seemingly calm expression, Su Lun quietly let go of her hand and said, "Sister, let's go in together, no matter what is in it, I believe we can solve it." ”

Yu Ruyi also nodded, took out the jade pendant that Liuyunzi gave him when he was leaving, and said, "If there is a real accident, don't dwell on it, it's a big deal to come back next time." ”

Both of them looked determined, encouraged each other, and after a few moments both of them adjusted to their best, and walked through the giant door.

"Hum—"

A ripple-like wave appeared on the door frame, and as the two entered, one wave after another, and after the two of them completely stepped into it, the ripple disappeared again, as if nothing had appeared.

Suddenly there was a wind outside, and the wind swept up dry bones and scattered in all directions, but because of the resistance of the hills, they came back and finally fell to the ground and shattered into powder.

And the blood moon in the sky actually brightened up a little more at this moment, like a huge blood-colored eye.

"Squeak...... Bang!"

Naturally, the two of them didn't know the movement of the outside world, and they didn't even observe the surrounding environment, and when they heard the sound, they looked at it suddenly, but found that the door behind them was closed.

There wasn't even a handle on the door, and the two tried to pull it, but they couldn't pull it open at all. The two looked at each other and smiled bitterly, but there was no way back in their hearts, they could only move forward.

It's strange to say, obviously you can't see clearly from the outside, and the courtyard seems to be foggy, but now the sight is a little clearer, at least you can see the huge palace around you, as well as some large and small trees planted next to you.

"Sister, let's not be separated, let's explore this place together. Su Lun said in a low voice.

Yu Ruyi snorted and said, "Look at this layout, it seems to be divided into front and back yards, and there are houses on both sides of the front yard, let's go see them one by one, be careful." ”

After the two of them had discussed, they walked towards a room on the left.

When they arrived at the door, the two of them did not go in directly, but first observed, and found that this room was only made of ordinary stone bricks, and there were no patterns carved on it, obviously just the most ordinary house.

But they didn't let their guard down, and slowly walked in the door, and with a slight push, the door opened directly.

To the surprise of the two, there were no strange beasts in the door, no danger, not even too many things, just a simple bed, a set of tables and chairs.

The two walked over to take a look, and found that these tables and chairs did not know how long they had existed, and many places were a little rotten.

The walls around were covered with a layer of dust, and it seemed as if no one had lived there for a long time.

The two searched around and found nothing, so they retreated and walked towards the next room.

When you open the door, you will find exactly the same room, the exact same layout, and even the style of the tables and chairs.

Su Lun walked to the table and chair and found that it was also something that had been around for an unknown period of time, although he didn't know the material, it was obviously the same as the previous one.

They walked through several rooms in a row, and found that this row of rooms looked like they were duplicated.

Walking out of the last room, the two found nothing.

"Sister, it seems that there used to be people living here? And it's so neatly arranged, it's a bit like ...... It's like the residence of our disciples of the Tianyun Sect. ”

Yu Ruyi nodded, and then looked to the other side, there was also a row of rooms there, I don't know if it was the same as the room layout here.

Instead of approaching the door that led to the backyard, the two walked back to the gate and then to the room on the right.

When they opened the door, a smell of dust came to their faces, and the two of them resisted the urge to cough, and it took a while to see the contents of the room clearly.

The first thing that greeted us was a Dan furnace.

After Yu Ruyi saw it clearly, he walked directly over, looking at the rusty Dan furnace in shock, his eyes were full of disbelief.

Su Lun also went to take a look, but he didn't find anything strange, and couldn't help asking, "Sister, is this Dan furnace very different?"

Yu Ruyi nodded and muttered, "Mother Golden Furnace...... This is the Heavenly Xuanmu Golden Furnace!"

"Heavenly Xuanmu Golden Furnace, what is it?" Su Lun had never heard of this name at all, and he had never seen it in a book.

Yu Ruyi said: "The Dan furnace we usually use is generally made of ordinary metal, and the better thing is to add some magic circles to it, which can speed up the operation of Xuan Qi or converge the furnace fire. ”

"But there are more precious Dan furnaces, but they use some extremely rare materials, which may have some unique characteristics in themselves, and after being made into a Dan furnace, they can have the effect of adding wings. ”

"And this," Yu Ruyi said, pointing to the seemingly ordinary Dan furnace in front of him, "the material it uses is the legendary Tianxuan Mother Gold. ”

"Tianxuan Mother Gold is a unique material, born in a place with a very high concentration of Xuan Qi, and affected by the extreme concentration of Xuan Qi, when it is made into a Xuan Qi, it will automatically absorb the surrounding Xuan Qi, and can also balance the concentration of Xuan Qi, which has a unique advantage in alchemy. ”

Su Lun nodded, he knew very well that when refining the pill, the furnace fire must be even, and the bottom of the furnace must be heated and balanced, so that the liquid medicine in it can better react, and the medicinal effect can be played evenly, and finally it will be reflected on the Cheng Dan, that is, the pill ingredients are good and the quantity is large.

Yu Ruyi continued: "This Heavenly Xuanmu Gold is very precious, and our Tianyun Sect used to have some of it, but then it was lost after the death of Emperor Dan, which can be described as a big loss. But I didn't expect to see this material again here. ”

Su Lun stroked the Dan furnace and frowned slightly, "Sister...... This day the Xuanmu gold is so precious, it will rust?"

Yu Ruyi was puzzled at the moment: "I also think it's incredible, according to reason, this kind of thing can't be rusty, and ...... I feel that although this material is very similar to Tianxuanmu gold, there is always something missing. ”

She pondered for a moment and muttered, "Like...... Yes, there is a lack of agility that can interact with the Xuan Qi of Heaven and Earth, as if all the spiritual energy has been drained away. ”

"Is that still useful?" Su Lun said and wanted to put this thing into the spatial ring on his hand, but was surprised to find that the Dan furnace seemed to be rooted and did not move at all.

"Well, sister, this thing is weird. ”

Suren tried a few more times, but couldn't get it to move.

"Forget it, even if we get it out, it won't be of much use. Yu Ruyi said, and then the two looked at the rest of the room.

This room didn't have anything more than a Dan furnace at all, it seemed like a separate alchemy room, and it wasn't even better than the alchemy room of the Tianyun Sect, at least there were things to rest under it.

They looked a few more rooms, only to find that it was still laid out in the same way.

"This is so big, so much Tianxuan Mother Gold, I'm afraid it will cost a sky-high price. Yu Ruyi sighed.

When the two came to the penultimate room, they found that something was different.

In this room, in addition to the golden pill furnace of the Xuanmu that day, there are several statues, but they are all simple, and even the facial features are not very clear, like the random work of a child.

Su Lun studied carefully in front of a statue, and suddenly the corner of his eye seemed to see something.

He turned his head to look at the door, only to see a dark shadow flashing by, and before he could see clearly, it had disappeared.

"Who?!"

Su Lun shouted violently, and at the same time quickly walked to the door and opened the door directly, but there was still a faint mist outside, and there was nothing in sight.

"What's wrong?" Yu Ruyi hurriedly came to her side, and when she saw Su Lun's serious face, she hurriedly asked.

"I seemed to see a dark shadow flash in the doorway, but I couldn't see it clearly. ”

Yu Ruyi's face changed, after they entered the gate, they had never seen anyone else, what was the figure just now?

"Look here!" Yu Ruyi said hurriedly, pointing to a spot on the door.
