The iron sheet is thin, with a mysterious pattern on it that is slightly raised, and in the middle is a small mountain-like pattern with sharp edges. The overall material is neither gold nor wood, and it is full of unspeakable mystery. The whole body is blood-red, and it will not reflect when placed in the light, as if something inside will absorb all the light shining on it.

Lu Xu carefully sanded the lines on the surface of the iron sheet, and he couldn't figure out what it was.

"Shhhhh ”

Suddenly, Lu Xu screamed in pain, and his frosted fingers were cut by the sharp edges on the surface of the iron sheet, and a few drops of blood stained it. But when Lu Xu wiped the blood droplets on the iron sheet with his sleeve, he found that the bright red blood droplets stained on the iron sheet were not only not wiped off, but seemed to be absorbed, slowly penetrating from the surface of the iron sheet to the inside.

Not only that, but as the few drops of blood sank into the iron piece, they slowly converged in the middle, and slowly began to condense into a drop of blood in the hill-like pattern, and when the blood condensed, the iron sheet began to light up......

"Ah......h

The hand holding the iron piece was suddenly burned, Lu Xu couldn't help but scream, and unconsciously let go of the iron piece, and then something happened that made Lu Xu stunned. The piece of iron that was released by Lu Xu's hand stood so smoothly and steadily suspended in the air, constantly flashing with a strange brilliance. Lu Xu's eyes widened in horror and nervousness, he didn't know what was going on, and then in his frightened eyes, the iron sheet flickered violently a few times, and it turned from the original blood red to a bright turquoise......

At the moment when the iron sheet as a whole turned turquoise, a green filament of light shot out from the iron sheet and shot straight to the center of Lu Xu's eyebrows. Lu Xu suddenly felt a buzz in his head, and the whole person felt empty in an instant, as if he had fallen from a high altitude, and then there was a sharp pain in the center of his eyebrows, as if something had penetrated into his brain from the center of his eyebrows, Lu Xu's eyes were dark, and the whole person fainted all of a sudden......

I don't know how long it took for Lu Xu to wake up.

When he regained consciousness, the first thing he felt was a cold feeling coming from all over his body, and Lu Xu, who was undecided, was slightly frightened, not knowing what his current situation was. He shook his head in a hurry, and only after his brain was back in action did he begin to remember what had happened.

Lu Xu slowly got up from the ground and sat on the bed, the hut was already dark at the moment, the current time should be late at night, could it be that he had been unconscious for a few hours?

Wait a minute...... What about that mysterious piece of iron......

Lu Xu was suddenly startled, looked at his hand, and then looked at the room, except for the ore debris lying on the ground, there was no shadow of iron in the house. Picked up the half of the ore that was still intact and held it in his hand, only the depression on the ore that was still clearly visible, reminding Lu Xu that everything that happened a few hours ago was true.

Could it be...... Flew away......

Thinking of the last time he saw the iron piece floating in the air, Lu Xu couldn't help but think so, but after checking the closed doors and windows in the room, everything was intact. If it flies away, it will definitely hit the doors and windows and leave traces, but there are no traces left.

Suddenly, Lu Xu seemed to think of something, and hurriedly took out a bronze mirror from the table and looked at his face carefully. But I found that the center of the eyebrows was intact, and there was no trace at all.

Just as he was about to put down the mirror, suddenly, out of the corner of his eye, he accidentally noticed that something seemed to have burned a big hole in the clothes on his chest. Lu Xu's heart moved, and he tore his clothes open, and the scene that entered his eyes made him stunned.

I saw a pair of turquoise patterns printed on the chest of **, oval as a whole, dense mysterious lines at the edges, and a hill-like pattern in the middle. It was the mysterious pattern that I had seen on the surface of the iron sheet not long ago.

"What's the matter, how did this thing get to my chest. Lu Xu stretched out his hand suspiciously to scrub the pattern on his chest, and there was no abnormality in the tentacles, as if he had grown here before.

At this moment, Lu Xu, who was studying the pattern on his chest, felt a heat in his chest, and then the green light of the hill in the center of the pattern flashed.

In the blur, Lu Xu felt that the environment around his whole person seemed to flicker, and his eyes went dark, and then a dazzling light pierced his eyes, and he couldn't help but moan and close his eyes.

After getting used to it for a while, Lu Xu opened his eyes, and when he opened his eyes, Lu Xu's mouth was suddenly so stunned that he didn't close it for a long time, as if he had seen something incredible.

What appeared in front of Lu Xu was a square of vast and flat land, Lu Xu stood in the middle of the whole land, the area of the whole land was about dozens of acres in size, standing in the middle, the whole seemed extremely empty. This land is like a barren land, the only protrusion is only in the center of this land, not far from where Lu Xu is, there is a stone tablet one person high, but other than that, it is empty.

With a strong sense of curiosity, Lu Xu stepped forward to look at the mysterious stone tablet.

said that it was a stone tablet, but Lu Xu felt that the material was not gold or wood, and he couldn't tell what it was. The whole body is turquoise, and the dragon flying and phoenix dancing on it are engraved with four golden characters of "Linglong Secret Realm".

In the sky and around this space, a trace of colorful light constantly twists, changing into various strange shapes. Then it turned into little by little colorful points of light, like colorful spiritual rain sprinkled on the bare ground, making people feel refreshed and indifferent and tranquil.

Is this a dream?

Lu Xu looked at his body, it was still the black robe of the Zixiao Sect just now, and the whole person seemed to suddenly appear in this place out of thin air.

After being stunned for a long time, Lu Xu pinched his thigh fiercely, and a sharp pain came, only to know that he was not dreaming.

Lu Xu circled around the stele several times, but he didn't see any fame, he just felt that there was mystery everywhere here. After pondering for a while, Lu Xu decided to explore this place, the soil here is delicate and soft, the humidity is moderate, and there is no impurity, stepping on it is like stepping on soft and wet sand. Following a certain direction of the stone stele, Lu Xu walked over. It wasn't until he walked to the edge of this space that he felt a strange elastic force, making it impossible for Lu Xu to cross it no matter how hard he tried, but when he looked at it with the naked eye, he felt that there was endless darkness in the distance, as if it was a black hole that could even be swallowed by light.

There was nothing in the entire space except for himself and the stele. Lu Xuxin grabbed a handful of soil on the ground and looked at it carefully, the soil was soft, but the soil was turquoise throughout. A small piece of the ground was opened, and it was constantly tumbling like a substantial point of colorful light, but there was no smell of earth, which felt very strange.
