Are you crazy? Who asked you to hunt for treasures in the emperor's harem?

Half an hour later,

The stone chamber under the starry sky,

Ye Fan and Liu Mengying looked at each other, and saw the speechlessness and puzzlement in each other's eyes, because the two of them searched the entire stone chamber, and Ye Fan even dug up several stones, but he didn't find anything that looked like a treasure...

"Brother, I now understand why those skinny guys were so angry yesterday... They may have encountered a similar situation as us..."

Liu Mengying said quite depressed.

"It doesn't make sense... the teleportation array at the foot of the mountain... is just for reaching a place like this where there are no treasures..."

Ye Fan scratched his head. "Could it be that this stone chamber... has a special meaning to the person who built it... That's all?"

“It’s a bit of a headache…”

Liu Mengying walked to the edge of the stone chamber and looked around at the dark and empty surroundings. "Brother, judging from the situation on the first mountain, if we wait here until sunrise tomorrow, we may be able to directly see the next mountain we are going to!"

"Well, let's rest here tonight..."

Ye Fan agreed. Although he could find the seven peaks by looking for waterfalls, it would take a lot of effort. After all, when he and Liu Mengying first looked for them, they had to climb over several peaks with big waterfalls...

Soon, Ye Fan and Liu Mengying entered the tent to rest, but both Ye Fan and Liu Mengying kept their eyes open, not wanting to sleep at all, because they had been busy all day looking forward to the treasure of the Dragon Vein Heavenly Book, but in the end they didn't find any treasures, and they were very depressed...

"Little bean sprout, what's wrong with you?"

There was obvious doubt in Ye Fan's voice, because he found that Liu Mengying suddenly lifted the moisture-proof mat and put her ear to the ground.

"Brother...I...I seem to feel the breath of fire...well...to be more precise, it's the breath of Dan Fire!"

Liu Mengying thought for a while and replied.

"The breath of Dan Fire?"

Ye Fan was surprised, "Little Bean Sprout, can you sense the Dan Fire?"

"How should I put it... I was practicing a while ago... I mastered some of the power of the seven-colored rays of light... Then I found that I seemed to have some special perception of fire... I discovered it by accident when I was studying the colorful cicada Gu Dan fire you gave me yesterday..."

At this point, Liu Mengying frowned, "But I'm not too sure... It feels a little weak..."

"Xiao Douya, is the Dan Fire you sensed right below where you are lying now?"

Ye Fan was obviously very interested in Danhuo.

"Ok!"

As soon as Liu Mengying nodded, Ye Fan spoke again: "Little Bean Sprout, we can't sleep now anyway, let's go look for it!"

"Good~"

...........

Immediately, Ye Fan took out a sharp sword and began digging on the ground.

Soon, the entire stone chamber was filled with the earth and rocks dug out by Ye Fan and Liu Mengying. Liu Mengying then put the dug earth and rocks into the Naxuan Ring...

"Big brother, it should be a little lower!"

Liu Mengying put her ear close to the ground, sensed for a while, and then spoke.

"Okay!~"

Ye Fan responded, and the sword in his hand quickly swept across and started digging again.

After a while, Ye Fan stopped what he was doing. Liu Mengying also noticed something. She used the dimmed black stone lamp in her hand to take a closer look and exclaimed in surprise, "Big brother, is this a black pattern magic array?"

"Ok!"

Ye Fan nodded slightly, "Little Bean Sprout, please move aside for a moment, I will break this magic circle!"

Soon, Ye Fan's right hand fingers condensed into white needles, which kept crossing the hard stone below, stabbing it from time to time, and the mysterious pattern magic array on the stone soon disappeared...

"Kacha! Kacha!"

After a few slight noises, Ye Fan cleared a hole for one person to pass through, and a bright firelight suddenly shone out. At the same time, a scorching burning sensation pounced on Ye Fan and Liu Mengying.

"go!"

Ye Fan and Liu Mengying jumped into the cave one after another and came to a space of three meters square.

"Brother, this entire cave is filled with Dan Fire... and Dan Fire is of water attribute... The flames are bright white, not fiery red!"

As soon as Ye Fan sealed the entrance of the cave with stones, Liu Mengying's surprised cry was heard.

"really……."

Ye Fan nodded slightly. His body was much stronger than that of an ordinary person, so he didn't feel any pain from the burning of the Dan Fire in the stone cave. What surprised him was that the Dan Fire automatically kept a distance from Liu Mengying. Every time Liu Mengying took a step forward, the Dan Fire automatically took a step back...

"Little Bean Sprout, why don't you try to practice with Dan Fire~"

After thinking about it, Ye Fan suggested.

"Me?"

Liu Mengying, who was controlling a ball of Dan Fire to condense into a cotton ball, turned around and asked, "Using Dan Fire to practice?"

"Ok!"

Ye Fan nodded, "Little Bean Sprout, you have a strong control over flames. With the colorful flames in your body, you can try to absorb a small part of the Dan Fire. The Dan Fire in this stone cave is still of water attribute. Compared with other Dan Fires, it is much milder... Those Dan Fires are actually Xuan Qi in essence. You can absorb and refine the Dan Fire as you usually do when you practice with Xuan Qi Stone!"

"However, when the Dan Fire first enters the meridians and source points, you may feel a tingling sensation. Remember to control the amount of Dan Fire you absorb!"

After a pause, Ye Fan added.

"Oh, okay~"

Liu Mengying nodded, then sat cross-legged, closed her eyes, and began to circulate the mysterious energy in her body.

Soon, the surrounding Dan fire seemed to sense something and began to turn into strands and move closer to Liu Mengying. Liu Mengying was burned by the Dan fire at first, and her body trembled in pain. Her brows knitted tightly and cold sweat broke out on her forehead, but her brows soon relaxed...

After watching Liu Mengying steadily absorb the Dan Fire for a while, Ye Fan turned to look around.

The entire stone cave was extremely empty. Apart from the bright white fire, there was only a small stone platform and nothing else.

Immediately, Ye Fan strode towards the small stone platform and found a depression inside the stone platform. Inside the depression was a pill with a white glow on the surface, which looked a bit like starlight. There was also a jade slip under the pill. The pill fire that filled the entire stone cave did not burn the pill or the jade slip, but stopped outside, as if an invisible force blocked it outside...

Ye Fan picked up the pill emitting a white glow with curiosity and looked at it. "This seems to be some kind of medicine... Such a strong medicinal power... yet so gentle..."

Afterwards, Ye Fan took out the jade slip in the groove and checked it.

"Oh my gosh! Marrow Cleansing Pill?!"

After seeing the contents recorded on the jade slip, Ye Fan was really surprised, because the jade slip contained the recipe for the Marrow Cleansing Pill.

According to what Zhong Ming said when they were in Qinhuai City, if one wants to enter the final stage of the Xuanqi cultivation hall, that is, to become a monarch-level Xuan cultivator, one must undergo marrow cleansing, otherwise one will stop at the ninth level of the Venerable Rank for life. The Marrow Cleansing Pill is the elixir that can cleanse the marrow of Xuan cultivators, but no one has heard of anyone being able to refine the Marrow Cleansing Pill... It was once believed to have been lost...

Soon, Ye Fan also sat on the ground, but he did not absorb the pill fire, but studied the recipe of the Marrow Cleansing Pill on the jade slip, as well as the Marrow Cleansing Pill with a layer of faint fluorescence on the surface...
