The walls of this passage are adorned with lamp-like ornaments every few meters, but instead of candles, they are inlaid with night pearls, which emit a faint fluorescence in the dark passageway, illuminating the scene inside.

Yun Fan and Qinglian walked in this passage for a long time, and found many stone chambers along the way, but the door was opened, and the inside was also empty, obviously having been cleaned by the people who had come before.

All the way to the end of the road, they didn't find anything of value.

Then they returned along the road, so many passages, there was always something left behind, right? Yun Fan didn't believe it, the huge palace didn't even have anything valuable.

When they returned to the main hall, they found that Wang Jie was gone, so they must have picked a road to hunt for treasures.

Ignoring him, the two of them chose a passage again and quickly dodged in.

Within a quarter of an hour, the two of them turned back again with somewhat ugly expressions, "I don't believe it, choose one more!" Yun Fan said ruthlessly.

Finally, in the third channel, they finally made a discovery, if there was no gain, Yun Fan really couldn't help but go crazy.

In the innermost stone chamber of this passage, which was also ransacked, Yun Fan inadvertently found some clues on the bare walls.

At that time, he saw that it was an empty stone room again, and in a moment of anger, he couldn't help but smash his fist against the wall, and the spiritual power on the fist subconsciously poured out, and then, he found something strange.

This wall actually absorbed the spiritual power emanating from his fist!

There's something weird! There's got to be something behind this wall!

Yun Fan called Qinglian over, and the latter also tried it, and like Yun Fan, her spiritual power was also absorbed.

"How can this be?" Qinglian frowned, she had just used the Qinglian Companion Sword to slash a few times on this wall, but she didn't expect that there was not even a single scratch left!

"There should be a mechanism behind this wall, and only by opening this mechanism can we go behind the wall. Yun Fan touched his chin thoughtfully.

"But we don't know how to break the lock. Qinglian said helplessly.

"This wall can absorb spiritual power, so where does the spiritual power that is absorbed go in?" Yun Fan muttered to himself, "Absorb spiritual power, spiritual power. ”

"I know!" Yun Fan's mind suddenly flashed and said with some surprise.

"What's the matter, have you thought of a way to crack this mechanism?" Qinglian couldn't help but be a little surprised when she looked at Yun Fan's appearance.

"Well, it should be, if I'm right. Yun Fan said in a deep voice, "Forget it, let me experiment first, I'll know after I try it." Yun Fan raised his palm, and his spiritual power worked silently.

The palm of the palm is close to the wall, and then the spiritual power in the body is flowing towards the palm of the hand, and then along the palm, slowly injected into the wall.

As time passed, Yun Fan's forehead couldn't help but sweat a little, and he continued to input spiritual power into the wall, and the spiritual power in his body was rapidly consumed.

Could it be that I was wrong? Yun Fan's eyes couldn't help but show an unwilling look, at this time, most of the spiritual power in his body had been consumed.

Just when he couldn't help but want to give up, the wall that had been moving finally changed a little.

I saw that the original blue and black wall was slowly turning red at this time.

Seeing this change, Yun Fan, who was still a little discouraged, suddenly perked up, and the spiritual power on his palm was rapidly output again.

Qinglian naturally saw the changes on the wall, and without hesitation, she also pressed her little hand on it, constantly outputting spiritual power.

With the addition of Qinglian, the changes on the wall suddenly accelerated a lot, and after a while, the entire wall became red, reflecting the cheeks of the two people red.

"Click!"

It didn't take long for a soft sound to ring in Yun Fan and Qinglian's ears, and then they saw the crimson wall suddenly dent in, and then slowly moved to the left, until the swarthy entrance was revealed, which was one person tall and two people wide, before it stopped.

It's done!

Yun Fan and Qinglian looked at the entrance with some joy, it was so hidden, there must be something good inside!

"Yun Fan, how did you know that this mechanism can only be opened with spiritual power?" Qinglian asked with some curiosity.

"Actually, I'm just trying my luck. Yun Fan smiled bitterly, "I think if I were the Flame Ancestor, how would I set up the mechanism? ”

"In addition, this wall can absorb people's spiritual power, so I guessed that it might take a certain amount of spiritual power to open this mechanism, and sure enough, it was so simple that people couldn't imagine it. Yun Fan couldn't help but sigh.

This organ, the more people who are extremely deep in the city, the more they can't think of it.

"Follow me. ”

Without any hesitation, Yun Fan whispered to Qinglian, and took the lead in walking towards the entrance.

Entering this secret room, there was darkness everywhere in sight, but it was nothing for Yun Fan, after all, with his current strength, it was not difficult to see things in the night.

However, he was still a little unaccustomed to it, so he took out a few night pearls from the ring, flicked them to a few corners, and the secret room was brightened up in an instant.

Yun Fan squinted slightly at everything in the secret room, in the center of the room was a large alchemy furnace, the fire had long been extinguished, and the furnace body was full of dust.

On one side of the alchemy furnace, there was a shelf, on which were filled with all kinds of jade bottles and jade boxes, which were also covered with dust.

On the other side, there is also a shelf, on which should be placed medicinal herbs, but at this time, those medicinal herbs have withered and turned gray and black.

Other than that, there was nothing else.

"What is this?" Qinglian walked in, looking at the furnishings in the secret room, and couldn't help but be a little curious.

"This is the alchemy furnace, presumably the place where the Fire Flame Ancestor refines the elixir. Yun Fan said, "Yes, this Fire Flame Ancestor is so good at controlling fire with one hand, it is not uncommon for him to be able to refine pills. ”

Yun Fan strode to the shelf on the side of the alchemy furnace, waved his sleeves suddenly, and a gust of wind blew, and the dust on the shelf was blown away in an instant.

The dust that filled the room was blocked by Yun Fan and Qinglian's spiritual power shield, and it didn't fall on them.

When the dust cleared, Yun Fan looked at the shelf again.

Those jade bottles and jade boxes were all pasted with notes on them, on which were the names of the pills.

"Snow Spirit Pill, Qingfeng Pill, Jade Ginseng Pill. Yun Fan picked up a few bottles casually, looked at the words on the note, and read softly.

Yun Fan thought about it, gently unscrewed the lid on a jade bottle, and suddenly, a fragrance wafted out of it in an instant, and drilled towards Yun Fan's nose!

Smelling this fragrant fragrance, Yun Fan took a deep breath, and his spirit suddenly lifted his spirits, and a look of surprise appeared on his face, the pills in these jade bottles were so well preserved, after so many years, they could still be taken!

Looking at the shelves full of jade boxes and jade bottles, Yun Fan's little heart touched fiercely, and licked his somewhat dry lips, this time it was really hairy!

"So many pills?!" Qinglian looked at the dazzling jade box and jade bottle, and a look of shock also appeared in her eyes.

You must know that this elixir can only be refined by monks with strong soul power, and the price is quite expensive, even their Qing family is not much, and so many appeared in front of them at once, which scared Qinglian.

"This line of work has finally paid off. Yun Fan's face finally had a smile, so many pills finally made up for the regret of not having the essence of fire to refine the flesh.

Let Qinglian first pick a few jade bottles and jade boxes, if there is an emergency, you can take out the pills to take, she did not take the ring, so they discussed storing these pills here with Yun Fan first, and then distributing them after they went out.

Yun Fan didn't delay any longer, the ring in his hand shone slightly, and with a wave of his big hand, he swept away all the jade bottles and jade boxes on the shelf, and the shelves that were originally full became empty in an instant.

The two searched again, and after making sure that nothing was missed, they retreated.

After going out, Yun Fan didn't have a moment to rest, but ran towards the stone chambers he had searched before, he wanted to check again to see if the walls in those stone chambers also had mechanisms.

However, it is obvious that good luck will not always befall him, and he searched all the stone chambers he had searched before, but he did not find any secret rooms that could only be opened with the same spiritual power as before.

Yun Fan smiled a little helplessly after exiting from the last stone room in the depths of the Yongdao he entered for the first time, sure enough, he thought too much, how could there be a secret room in every stone room?

However, he was not depressed, after all, the mountains of jade boxes and jade bottles in the ring were enough for him to smile and blossom, even if it was half of the green lotus, he still had a lot.

Just as Yun Fan beckoned Qinghe from another stone room and was about to change to a new corridor, suddenly, there was a feeling of vibration from the ground under their feet.

Yun Fan was slightly stunned and looked at the ground with some confusion.

"Boom!"

Another vibration came, and Yun Fan vaguely felt as if it was a little bigger than the previous movement.

"Knock knock!"

The frequency of the vibrations became shorter and shorter, and the sound became louder and louder.

Feeling the constant vibration under his feet, Yun Fan's heart swelled with an ominous feeling, urging Qinglian to come out quickly.

Just as Qinglian walked out of the stone room, a crimson object suddenly appeared in the gap at the edge of the corridor.

When he felt the restless aura on the crimson object, Yun Fan seemed to have thought of something, and his face instantly became very ugly!

These things turned out to be the spirit of fire! And the irascible aura contained in them, even he would have a numb scalp when he saw it.

Qinglian also noticed it, her face instantly turned pale with fright, when she was outside, she absorbed this thing to make her feel uncomfortable, now this fire essence is a hundred times stronger than before, if she absorbs it, I am afraid she will be burned to ashes in an instant!

"Let's go!"

Yun Fan grabbed Qinglian, who was already scared stupidly, and kicked his feet violently, and the two of them turned into two lights and shadows, and rushed towards the exit of Yongdao!

The moment Yun Fan and Qinglian left, the depths of the Yongdao were filled with the fiery fire essence!
