The distance from the stone gate to the entrance of the cave is only five or six meters.

This short distance, the space is not large, the width and height are only about two meters, in this small space of more than ten square meters, under the illumination of the torch, it is almost clear at a glance.

The walls of the cave are uneven and irregular, and occasionally a few weeds are seen, but they are also dry and lifeless, and there is no sign of any mechanism.

Mu Qianmei looked at it for a long time, but found nothing, then stopped, stood still, looked around with her eyes, and then thought silently.

Mu Qianmei continued to check and said curiously:

"I remember that Master went in and out as if there was no obstacle, could it be that this stone gate was installed by Master after we went down the mountain?"

Mu Qianmei looked at the stone gate and the traces around the stone gate again, shook her head, and said:

"This stone gate is by no means just installed, looking like this, it has been some years!"

Liu Tingfeng said even more puzzled:

"It's been some years? That's when we had this stone gate, how can Master still be so smooth every time he goes in? ”

Mu Qianmei also said puzzled:

"Yes, I remember that I have also seen the master enter and exit this cave, it seems to be really smooth, and I can't feel that there is a stone door blocking it?"

Speaking of this, a flash of light suddenly flashed in her mind, as if she had found some clue, but it was fleeting and she didn't catch it.

She muttered to herself:

"If there is no door, you can come and go freely, which means that this mechanism is in this stone cave, and after entering, it is within reach."

"But how does this start and how does it close?"

They turned their gaze to where they had just entered the cave.

At first glance, this is a natural stone cave, which is the same everywhere, and the uneven stone walls are basically nothing special.

However, the careful Zhuang Wuchen still saw a small abnormality

On the right stone wall, a protruding stone is smaller than the surrounding protruding stones, but it appears smoother.

It's like someone has touched it all the time.

However, because the stones around it are larger than it, they are just covered up, and it is generally not easy to be noticed.

Liu Tingfeng saw its uniqueness, so he walked over, stretched out his right hand, and held the small stone pillar.

He tried to turn gently.

To the left, do not move.

To the right, do not move.

Push in, don't move.

Pull out, still don't move!

Liu Tingfeng couldn't help frowning, could it be wrong?

However, this small stone pillar is the most special, except that its surface is relatively smooth, and when you look closely, there are actually small gaps around it.

It's just that the stones around it are cleverly blocked.

It can be seen that this small stone pillar is not natural, but artificially installed.

It must be the switch that controls the stone gate mechanism.

But why can't it be turned?

Mu Qianmei, who was standing behind him, stepped forward and said:

"Why don't I try?"

Liu Tingfeng stepped aside and gave up his position to Mu Qianmei.

Mu Qianmei also stretched out her right hand, held the small stone pillar, and tried to turn it.

As a result, the stone gate remained unmoved.

The burning torches, at the entrance of the cave, were blown by the wind, so that the cave was also bright and dark

, adding a bit of mystery.

Both of them looked at the small stone pillar in front of them, their brows furrowed, and they thought hard.

This is obviously the switch that controls the stone gate mechanism, why is there no movement?

After a long time, Mu Qianmei's eyes suddenly lit up, and she guessed and said:

"When Master goes forward and exits, but it can be opened casually, is it possible that Master uses internal force to open it?"

Liu Tingfeng replied suspiciously:

"With internal forces? Won't that shatter all the stone pillars? ”

Mu Qianmei continued to think about it and said:

"I remember that Master once said that when the sword technique with the wind is practiced to the fourth sword, the corresponding internal force has also entered another realm, and it can be transmitted through objects."

"I think the little stone pillar we see now is just a cover, and the real switch may be behind this stone."

Liu Tingfeng felt that what his senior sister said was quite reasonable, but he hadn't tried to move through the stones, so he was a little hesitant for a while.

He had broken the lines in the wood through the bark of the tree.

He once shook the meridians of people through their skin.

But he has never practiced through a stone.

However, he still held the stone pillar, slowly mobilized his internal strength, and according to the heart of the fourth sword of the Suifeng Sword Technique, he exerted it inward through the stone pillar.

This is different from the previous way of exercising.

In the past, the practice was only to break the lines of trees, and when facing the enemy, it was also to break people's meridians.

But this time, instead of breaking the switch inside, you have to turn it on.

The first time he tried it, he touched the switch inside, and it was indeed as Mu Qianmei said, it was this stone pillar that blocked it inside.

He didn't dare to push too hard, for fear of accidentally breaking it.

The stone door did not open.

The second time he tried it, he used a little force, and felt that the switch could indeed be shaken, but he still couldn't open the stone door.

In the third attempt, he used a little internal force to rotate from left to right, and the switch was also slightly turning.

However, the stone gate still did not open.

On the fourth attempt, he rotated in the opposite direction, from right to left, and this time, the switch rotated more smoothly.

He didn't dare to be greedy for work, but slowly exercised his work, followed the rotation of the switch, and gently added force.

"Smack!"

Only a crisp sound was heard, and the switch finally touched the mechanism.

The stone door inside slowly moved to both sides.

"Huh...... Finally opened! ”

Mu Qianmei waited nervously on the side, and when she saw that the stone door was finally opened smoothly, she couldn't help but say in surprise.

Liu Tingfeng was also very nervous due to the internal energy consumption, and fine beads of sweat oozed from his forehead.

And after the stone door was opened, he didn't dare to immediately retract his internal strength, for fear of damaging the switch, but continued to work and let the mechanism slowly reset.

Mu Qianmei did not immediately walk into the stone cave, but took out the handkerchief she carried with her and gently wiped the beads of sweat on her forehead for Liu Tingfeng.

It wasn't until Liu Tingfeng completely retracted his internal force that Mu Qianmei asked softly:

"How does Tingfeng feel? Would you like to rest for a while before we go inside? ”

Liu Tingfeng breathed a breath, stood up, and replied with a happy expression on his face:

"Thank you, senior sister, I don't care, the gap between me and the master is still very big, the stone door that the master can open casually, I have to spend so much internal force and energy to open, let's go, let's go in and have a look!"

Mu Qianmei was relieved:

"The reason why the master opened it so easily, firstly, is because of his deep internal strength, but, more importantly, the mechanism itself was designed by himself, and he is more familiar with the structure of the mechanism.

The two of them did not walk in recklessly, but under the illumination of the torches, they looked at the situation of the stone gate clearly, and felt that there was nothing abnormal, so they raised their steps lightly and slowly walked inside.

Walking into the stone gate, there is a passage about the size of the entrance, which is also two meters wide and two meters high.

The left and right sides and the roof of the cave are natural, uneven stones.

Only the road on the ground has been rested, and the uneven stones have been leveled, and at first glance they have been swept away with a sword.

Under the illumination of the torch, Liu Tingfeng followed the lines of the sword on the ground, and couldn't help but smile and said:

"The master actually used the wind sword technique to smooth the ground, the mechanism of this cave can only be opened with the internal strength of the wind sword technique, and the road in this cave is swept flat with the wind sword technique, I think, this cave is named the wind cave!"

Mu Qianmei replied without thinking about it:

"Well, this name is worthy of its name, the stone cave where the master practices can only be entered by those who know how to follow the wind swordsmanship, such a setting, outsiders can't enter even if they want to!"

As they spoke, they had already walked more than twenty meters.

This is a square hole, stepping into the stone gate, there is no cave.

Inside turned out to be a large stone house.

It is a real stone house with a stone roof and floor, and the walls on the front, back, and left and right are also stone.

It is about 12 meters high and has an area of about 200 square meters.

On the stone wall in front of you, there is a big word "quiet" engraved, as if with mysterious magic, making people look at it, and the impetuous atmosphere in their hearts suddenly disappears.

Liu Tingfeng said with emotion:

"This word has gone beyond the scope of dancing swords with the wind, and the master's realm is really beyond our reach!"

Mu Qianmei replied calmly:

"The master has already stepped into the realm of swordsmanship, and it is no longer in the realm of swordsmanship!"

Below the static character, there is a two-meter-wide, six-meter-long long stone table, flat and neat, square, with pen, ink, paper and inkstone neatly arranged on it, it seems to be the desk where Ye writes and paints with the wind.

On the left side of the stone house, against the wall, there is a large weapon rack, on which all kinds of strange-shaped weapons are stored, and many weapons are ancient weapons at a glance.

On the right side of the stone house, there are three rows of bookshelves, each with six floors, and each floor is neatly filled with various books, like a large study with a rich collection.

The empty space in the middle is like a martial arts training hall.

After a brief look, the two of them first found a few places where kerosene lamps were placed, and it seemed that the ventilation conditions were still very good, so they used the torches in their hands to light all the oil lamps.

Inside the stone house, it was as bright as day.

The air inside is not stuffy, and it is estimated that there must be vents left in some hidden places.

After lighting the oil lamp, the sister and brother first walked to the desk in front of them.

When I approached the desk, I found that on this smooth bluestone table, under a pen holder carved with bluestone, there was a letter pressed.

The pen holder was pressed against only one corner, and I saw a row of flowing and vigorous calligraphy written on the envelope

"Love Pavilion, Fluttershy herself!"

Ye Suifeng even left them a letter, it seems that he had long expected that they would return to Wujian Mountain and enter this stone house smoothly!

Mu Qianmei and Liu Tingfeng looked at the familiar handwriting, and the extremely kind voice and smile of the master naturally appeared in their minds.
