A slight buzz and tremor emanated from his palm, causing Ling Feng's attention to quickly focus on the area he was touching, and at the same time, his arm was also retracted.

After staring carefully for a moment, he was surprised to find that the wall had already been divided into countless areas of different sizes by cracks, and the place he touched happened to be one of the relatively small and irregular shapes.

As the humming became clearer, the area covered by the palm began to glow faintly, and then slowly detached itself from the wall and floated towards itself.

Finally, it stopped a few feet in front of it, within reach, and stopped moving.

"Huh?" Seeing this, Ling Feng circled around it, and then stretched out a finger and pointed it at the center of the floating light sheet, "P, p, p" The touched light sheet made a mechanical sound, and at the same time it rippled and emitted dazzling light, and finally slowly dimmed, condensing into a thin microwave crystal, and a light red flame could be clearly seen dancing in the center of the crystal, vivid.

Ling Feng played with the crystal clear flakes that were only the size of his palm, and were somewhat amazed at the rich energy emanating from its interior.

Just the magic energy that inadvertently escaped, it was too many times more than the ore he absorbed, and he vaguely felt that this energy was very pure, and I am afraid that the value of a single round was not comparable to ordinary ores.

If you can absorb this crystal and use it for cultivation, I am afraid that it will get twice the result with half the effort, Ling Feng thought so, but immediately shook his head and denied his thoughts, if so, I am afraid that I will die because I can't withstand such an energy explosion.

After thinking about it, he took out a piece of cloth and wrapped it in his hand, and put it in the collar on his chest.

......

There was a simple red stone door on the wall in front of him, and the wall no matter how much it was touched, no matter how it was touched, it no longer reacted.

At this time, Ling Feng roughly understood that every wall should have such a mechanism, as long as someone touched it, they would get some rewards, and then there would be 4 doors leading to nowhere.

Since this is the case, then you don't need to rush out, and you can get all the benefits first.

Ling Feng made up his mind, turned around and walked towards the other wall.

After walking for about a few tens of meters, the floor tile under his feet suddenly sank, Ling Feng hurriedly took seven or eight steps backwards before stopping his figure, and waited for a long time to make sure that there was no danger in the distance, before walking towards the place where he had sunk just now.

As soon as he got closer, a flash of turquoise fluorescence flew from the sunken floor tiles, and before he could react, the fluorescence rushed straight in the direction of ten o'clock, and disappeared from view in the blink of an eye.

And such an inexplicable thing happened four or five times in succession when it reached the other end of the room, but after Ling Feng obtained another crystal rippling with blue waves, he did not open a new door, and the next two walls were the same, obtaining ink-colored and pale gold crystals respectively.

"It seems that I can only go back to where I came and go out through the door I just saw. Ling Feng, who had obtained the four spars, thought silently.

On the way back, nothing strange happened, except that when I came to the center of the room, there were three more treasure chests, which were suspended in the air, and they were gold, silver, and brown.

I guess I triggered the reward that was activated by the four walls, which is really good, and I have been getting benefits.

When I walked to the front, I found that each treasure chest has a lock hole, presumably with a corresponding key to open it.

It's a pity that no trace of the key was found, otherwise I could have taken more things out again.

It's just that since the box is here, then the key must also be in this space, thinking of this, Ling Feng hesitated a little, his strength is not good, if the treasure is at his fingertips, it is just that, but let himself go to find it deliberately, I am afraid that how many lives are not enough for him to toss.

After thinking about it clearly, Ling Feng's heart also settled down, so he tried to overcome the temptation and took a step through the treasure chest in front of him.

"I don't know what this key is for. As he walked, he took out the key of the ice crystal that the old man of the ferry boat had given him with a shimmering blue light.

What Ling Feng didn't expect was that as soon as his words to himself fell, there was a "click", and a crack suddenly appeared in the ice crystal in his hand, and then a fragment split out of the crack, directly bypassing him and shooting behind him, followed by the second, third...

Three fragments in a row, split from the ice crystal key, flew towards the three treasure chests not far behind him, and then drilled into the lock hole, and then there was a gratifying scene, the three treasure chests were actually opened, and the three objects were lying motionless at the bottom of the box, appearing in front of their eyes.

At this time, Ling Feng looked at these three objects, but he didn't know what to say, "It seems that the old man really gave himself a lot of benefits, and this box was opened by himself so easily." Thinking about it, he looked at the ice crystals in his hand again, "It's not completely broken yet, there should be a lot of things to be obtained later." ”

Putting away the broken ice crystal key, Ling Feng's gaze fell on the three objects again.

First of all, there is a somewhat shabby brown chest, in which lies a pendant in the shape of lightning, and the dark purple color reveals a jet-black luster, which is very strange.

Ling Feng tried to use his own magic energy to make contact, wanting to see if there would be any changes, but the result was unsurprising - there was no response.

Ling Feng took it out of the bottom of the box and put it around his neck, and the moment he put it around his neck, a wonderful connection seemed to be established between this inconspicuous pendant and himself.

This connection goes straight to the depths of one's mind through the divine vein, presenting the state of the pendant in its entirety, and he can also use his spiritual power to explore its internal space at will.

Since these days of practicing magic, although I still can't use magic, and my body only feels more energetic than before, there is no major change, but my mental power has changed drastically.

Ordinary people can't be called to have spiritual power, at most it is called energy, the most obvious example is that if a person is overworked, everything will be slow and inefficient, drowsy, magicians are even more so, whether it is cultivation or the use of magic, in addition to consuming magic energy, it also consumes a lot of spiritual power, once the mental power is exhausted, even the most powerful magician will fall into a weak state, vulnerable.

And now opening the pendant was exactly one thing that required Ling Feng to consume his mental power.

"It turns out that this pendant actually has the function of storage space!" Ling Feng shouted out in surprise at once, since the last time he saw Gu Haotian and Kun Peng have storage bags, they can put a lot of things in it and carry them around, and they can only carry large bags and small bags on their backs as if they were moving, so I don't envy them, I can't imagine that I have such a magical treasure so soon, and it looks like it is even much higher than theirs, how can I make myself unhappy this time.

Without a moment's hesitation, Ling Feng used his mind to manipulate the pendant, absorbing all the baggage behind him.

"Whew...", calming down his excitement a little, Ling Feng immediately looked at the silver box on the other side, it seems that greed is not bad sometimes, at least you can reap a lot of benefits.
