The place where the wordless stone tablet is located is a platform, and not far behind the stone tablet is a mountain wall.

Before the space was upgraded, this mountain wall was not full of grass, and there was nothing surprising except that it was very flat.

But when Xia Rufei climbed onto this platform, he saw at first sight that there was a black cave on the mountain wall. The entrance of the cave was very regular and flat, and it was obviously impossible to form naturally.

Xia Ruofei stood there in a daze, staring at the cave for a while.

This should be the second artificial trace that appears in the space. The first place is the wordless stone tablet.

Xia Rufei looked at the entrance of the cave and felt a little scared.

It turned out that a stone tablet was fine. Although after investigation by my mind, Xia Rufei also knew that this stone tablet was extraordinary, it was just a small stone tablet after all.

But now it is a big cave! The entrance of the black bead is like a ferocious beast that has chosen people to open its mouth, and there is a heart-pounding feeling of oppression in this quiet space.

Xia Rufei stood there, and many thoughts arose in his mind.

What exactly is there in this cave that emerged out of thin air? Will there be any danger? Could there be a living person appear?

After so long since he got the Spirit Map Space, Xia Rufei has always been the only master of this space, and his control over the space is increasing. Now a cave suddenly appears, which makes Xia Rufei feel a little panic inexplicably.

At this moment, he no longer had the intention to investigate whether the wordless stone tablet had any changes after the space upgrade. All his energy was concentrated on the cave.

Xia Rufei tried to release his mind, wanting to see if he could investigate.

However, there seemed to be an invisible barrier at the entrance of the cave, and his mind could not penetrate into the inside of the cave at all.

It seems that I can only go in and take a look.

Although Xia Rufei was not sure about this and he didn't want to enter this cave at all, it has appeared now, which is a big uncertainty factor and cannot be left alone in any case.

Xia Rufei approached the cave step by step. He walked very slowly, but every step was steadily, and his breathing was adjusted to the best state. His muscles were tightened. Once there was any movement, he could react as soon as possible.

When he arrived at the entrance of the cave, Xia Rufei pulled out the military dagger from his waist, grabbed it with his backhand, then took a deep breath, and walked into the cave...

The highest point of this cave is about two meters and the width is only about one meter five meters.

As soon as Xia Rufei entered the cave, he felt that the light was very dark, so he took out a strong flashlight and turned it on it, shining it inside, and found that it was a relatively narrow and long straight corridor, and the walls of the cave were very smooth, obviously made by hand.

Xia Rufei walked in carefully, and the high-top leather boots came into contact with the stone slabs in the hole, making a crackling sound, forming a burst of echoes in the cave, and the atmosphere seemed even more tense.

This corridor is about fifty meters away, and Xia Ruofei is moving forward with high alert.

Gradually he found that the corridor seemed to be slanted downward, which means he was always going downhill, getting closer and closer to the abdomen of the mountain.

While walking, Xia Rufei kept illuminating the walls and tops of the cave with strong lights, but no discoveries were found.

After a while, Xia Rufei walked to the end of the corridor.

After getting closer, Xia Rufei discovered that there was a turn of about 90 degrees here. Xia Rufei illuminated the flashlight and still found nothing.

He gritted his teeth and stepped into the new corridor on the right.

As soon as he came in, Xia Rufei felt that the spiritual energy here seemed to be a little richer than outside, and it was no longer an environment where he could not see his fingers. There was something embedded seven or eight meters above the top of the cave, emitting a glimmer, illuminating the corridor a little.

Xia Rufei took the flashlight and shone it on the light source, and then he found that the luminous thing was an egg-sized ball.

"Is this the legendary night pearl?" Xia Ruofei couldn't help but mutter to himself.

Because of the oblique downward trend of the corridor and the turning factor, the new corridor should theoretically not have any light, but Xia Ruofei only found that the corridor would not be dark at all after entering here.

Although the misty glow did not illuminate the corridor as bright as day, at least it could see the road clearly.

Xia Rufei did not put away the strong light flashlight. He held a military dagger in one hand and a strong light flashlight in the other hand, and continued walking in.

This new corridor is shorter, only about ten meters away.

Soon Xia Rufei walked to the end of the new corridor.

His eyes suddenly lit up...

At the end of this new corridor there is another turn, and then a stone chamber appears.

The light in the stone room is much stronger than the corridor, and it is also the misty pale yellow light.

Xia Rufei stood at the door of the stone chamber and could see that the inner wall and top of the stone chamber were inlaid with many luminous beads that I saw in the new corridor before, which illuminated the entire stone chamber.

Xia Rufei stood at the door for a moment, then walked inside. Although he didn't know if there would be any danger inside, he had already walked here and naturally could not turn around and go back.

He kept his vigilance and stepped into the stone chamber with one foot.

Various dangerous mechanisms, hidden weapons and other pre-imagined ones did not appear, and the wind was calm.

Xia Rufei did not relax his vigilance, and slowly walked into the stone chamber, holding the sharp military dagger tightly in his right hand.

He quickly observed the environment of the stone chamber.

This stone chamber is not big, it looks like it is only about ten or twenty square meters. Apart from the entrance where Xia Rufei came in just now, no other passages were found. Of course, it is unknown whether there are hidden passages.

Xia Rufei was worried that there would be no situation for a stranger. There were not many things in the stone chamber, and it could be seen at all.

The innermost position is a small stone bed, which is actually a whole big stone. However, from its flatness and the side facing the wall, there is a stone with obvious pillows. Xia Rufei then judged that this should be a bed.

There was also a round cake-shaped thing on the stone bed, which looked like stones and a bit like jade. Xia Rufei couldn't tell what material it was. From the appearance, it looked like the kind of futon I saw in movies and TV.

Then there was a stone table and two stone chairs inside the stone room. The small stone room still seemed a little empty.

Xia Rufei's attention soon focused on the stone table.

The stone table is larger than the desks used at home. Although there is nothing on it, it has a round bulge that is very eye-catching and a bit abrupt.

Xia Rufei walked carefully to the stone table, slowly reached out his hand, and carefully touched the round bulge.

No reaction...

Xia Rufei tried to turn it again, and then found that he couldn't turn it at all.

Or not?

Xia Rufei thought about it and simply pressed down hard.

This time, it seemed that he had found the right way, and the round bulge was suddenly pressed into the table by Xia Rufei.

Immediately afterwards, Xia Rufei heard a crackling sound. He quickly took a defensive posture, focusing on guarding against possible unknown dangers.

The danger still did not appear, and Xia Rufei's posture was in vain.

However, what happened next still made Xia Rufei widen his eyes involuntarily

On the ground next to the stone table, two stone slabs slid to both sides, and then a one-meter-square stone platform slowly rose with a crackling sound, and the stone platform was covered with a layer of blue halo.

Xia Rufei subconsciously took a step back, his face full of vigilance.

After two or three minutes, with a click, the stone table rose to its place, basically level with the stone table.

Xia Rufei looked closely and saw five light balls of various sizes distributed on the stone platform, all of which were wrapped in things, looming.

From left to right, the first light ball seemed to be a thin booklet, while in the second to fourth light balls, there was a jade plaque the size of a palm, which looked almost the same; in the last light ball, there was a small jade box.

Xia Rufei walked to the stone platform, and with a hint of curiosity, he slowly reached out to the light ball on the right to look the coldest booklet on the left. Xia Rufei thought that the most valuable thing should be the jade box on the right, so he went straight to the target as soon as he got up.

It’s a pity that this light ball seems to have the same effect as the space membrane wall. His hands cannot penetrate at all. A soft but extremely tough repulsive force makes his hands unable to penetrate the light ball at all.

Xia Rufei gritted his teeth and increased his strength, but it was useless at all.

He then used his mind to call the power of space to force the breakthrough, but it was still futile after working hard for a long time.

The greater the force Xia Rufei exerted, the greater the repulsive force, and he always maintained a delicate balance. The jade box was lying quietly in the ball of light, but Xia Rufei could only watch it with his eyes and could not get it at all.

He smiled helplessly and changed his target to the second-to-last light ball of the right. Inside this is a jade plaque. It is closest to the jade box and should be more precious than the other three things.

Unfortunately, the situation is exactly the same as before. No matter how hard Xia Rufei tried, he could not see or touch it. He could not even think about breaking through the protection of the light ball.

Xia Rufei was a little unbelievable, so he turned to the third ball of light to the right.

fail.

The fourth light ball is on the right.

Still failed...

Xia Rufei felt that he had used all his strength to feed himself, but he still could not shake the light balls. However, he could also feel that among these light balls, the first one on the right should have the strongest defense. When he reached the fourth light ball in the right, Xia Rufei could already make the light ball shake slightly with force, as if he could break into the inside at any time.

But it's just a little bit worse, no matter how hard I try, it's a little bit worse.

Xia Rufei had to turn his target to the last one, the first one on the left, with a small booklet of light balls inside.

He held his claw in his right hand and broke through hard. The familiar repulsive force came, but it had no effect...

Xia Rufei thought, and the invisible power of space combined with the power of his body, he tried again!

The halo of the light ball began to shake slightly.

Xia Rufei gritted his teeth and continued to increase his strength, and the shaking of the light ball became more and more powerful.

Finally, Xia Rufei roared and pushed it in with all his strength. The power of the five elements of space also burst out with huge power at the same time.

With a "pop" sound, the extremely flexible light ball finally broke suddenly, turning into spots and disappeared into the stone chamber.

Xia Rufei was sweating all over and gasping heavily at this time. He was really about to lose his strength.

I didn't expect that a light ball that looked very fragile actually had such a strong defense.

Xia Rufei felt that the power he used just now could even bend the steel pipe directly, but he just barely broke through.

He looked at the four light balls next to him and suddenly felt a little powerless.

I don't know when I can break them...

Xia Rufei believed that as his strength continued to increase, there would definitely be a day. As for himself now, he could only look at the things in the light ball and be jealous.

Soon, Xia Rufei's physical strength recovered a little, and he immediately focused his attention on the thin booklet.

Xia Rufei slowly reached out and grabbed the booklet.

Without the defense of the light ball, Xia Rufei easily grabbed the booklet in his hand.

It feels a bit silky when you buy it. This booklet is not made of ordinary paper, but it is more like silk, but it is harder than silk and can present a normal state of paper. Moreover, the faint golden light on its surface also made Xia Rufei realize that this should not be as simple as ordinary silk.

Because he tried it, it was impossible to tear open the booklet with his own strength. If it was ordinary silk, he just needed to use light force to tear it apart easily.

The cover of this booklet has no handwriting or patterns, so Xia Rufei slowly opened it with a hint of expectation... (To be continued.)
