In the middle of the hall stand several round stone pillars carved with a bunch of strange symbols. In the innermost part of the hall, there was a stone platform nine feet long and wide, half a meter high, and there was a blank space on the stone platform, but in front of the stone platform, a strange object was placed there.

Chen Feng and the two walked slowly towards the thing, and when they were only more than ten meters away from the thing, the two finally saw what the thing placed in front of the stone platform was.

It was a skeleton, a skeleton kneeling in front of the stone platform, with their backs to Chen Feng and the others. When they saw this skeleton, the two were shocked, because this thing was not a human skeleton, or rather, it was not an ordinary human skeleton.

The skull was at least forty centimeters long and wider than a normal skull. Under the skull, it is not like the shoulder blade collarbone of ordinary people, but two whole bones, without the slightest gap in between.

The two slowly moved to the skeleton, and found that there were not only two hollow eye sockets on the head of this skeleton, but also a vertical hole in the center of his eyebrows. The palm of the skeleton has only three fingers, two long and one short, and because his legs are kneeling, he can't see what he looks like, but Chen Feng is sure that he will definitely not look like a human.

"W-what kind of monster is this?" Li Cheng said softly.

"I don't know, it should be the aborigines here." Chen Feng guessed.

"The quality of this bone is also too good, you can see that the door panels, the furniture and everything are only a pile of dust, but the bone can still be intact. Think about how strong he must have been when he was alive. Li Cheng said with some amazement.

"If you think too much, the existence of this bone doesn't mean anything, if you look at its material, it's obviously different from our bones. That's the real reason why it doesn't rot. Or if your bone is made of jade, it will also last for a long time. Chen Feng said.

"Huh? Really, there's an amber-like layer on the outside of this skeleton. Strange, I thought that all animal bones on Earth should be the same. Li Cheng said like a curious baby.

"The same? How is it possible, the bone composition of crustaceans, invertebrates, reptiles and vertebrates is not the same, although most of them are composed of calcium, but this calcium is also divided into several kinds, what calcium carbonate, calcium phosphate and the like, so the bone composition is not the same. Hey, you don't understand it too much, I can only say that this thing in front of you is either more advanced than us, or it is not as good as us. Chen Feng explained.

"Oh...... Shall we pack this thing up and take it away? Li Cheng said.

"Bring a hair, a bunch of bones, what are you doing here?" Chen Feng looked at Li Cheng a little depressed and said.

"So what the hell are we here for?" Li Cheng felt that since he didn't take something when he came, it seemed that he couldn't say anything.

"Big brother, please we're here to find clues, by the way, let's see if we can find the Guardian Crystal, don't you want to go back? Don't want your Lolo anymore? But I still want to cling to it. After saying this, Chen Feng didn't pay attention to Li Cheng anymore, but squatted in front of the pile of bones in front of him and stretched out his hand to remove the three-fingered hand that was blocking his leg.

"Smack......

A soft sound appeared on this skeleton, startling Li Cheng. It turned out that when Chen Feng flicked the three-fingered hand, the arm of this skeleton suddenly broke apart, fell directly from the skeleton, and smashed to the floor.

"Broken ...... Broken? It's been a long time, this thing is so fragile? Li Cheng said in surprise.

"What's so strange about sitting there for so long. Well? What is it? Chen Feng saw that under the three-fingered hand, there was a piece of jade the size of a thumb, and he carefully picked up the jade.

The jade is shaped like a crescent, with a thin groove on the inside of the crescent, and a gentle stream of heat seeps into Chen Feng's body, making people feel more comfortable.

Chen Feng looked at the jade in his hand, then at the skeleton in front of him, he stretched out his hand again and dialed it to the other hand of the skeleton.

"It's weird, friend, this thing is obviously only half of it, I'll see if the other half is under your hand." Chen Feng muttered as he moved his hands.

Sure enough, after Chen Feng removed the other palm of this skeleton, under that palm, there was really a jade stone lying there. This jade is oval-shaped, with a thin protrusion on one side of the jade.

Chen Feng smiled knowingly, picked up this piece of jade, looked at it carefully, and then he spliced the two pieces of jade together.

"Click......

With a soft sound, the two pieces of jade fit together, forming a complete round jade, if you don't look carefully, it is really difficult to find that there is a thin gap in the jade.

"What a beautiful jade, show me." Li Cheng stretched out his hand, snatched the jade from Chen Feng's hand, and looked in the direction of the door.

At this moment, neither of them noticed, a faint white light shot in from the outside, directly shining on the jade, and the other side of the jade was on the stone platform behind Li Cheng, showing half a strange picture.

Li Cheng raised his hand and looked at it for a long time, but he didn't find anything special, he put down his hand, threw the jade back to Chen Feng and said, "It's just an ordinary piece of jade, nothing special." ”

"Then you still rob it." Chen Feng said with some amusement.

When the jade was removed from the light, the painting on the stone platform behind him was gone, so even Chen Feng didn't notice the vision of the jade in his hand.

At this moment, there was a sudden exclamation from outside the gate, Chen Feng hurriedly stood up from the ground, and the two of them looked at each other and rushed towards the door.

Five minutes ago, outside.

Ding Qingyue sat alone on the steps of the door, staring at the water-soaked road in front of him in a daze. Suddenly, a small black shadow flashed from the bottom of the water, and Ding Qingyue instantly became alert.

She wasn't sure if she had seen the fleeting shadow, but her instincts told her that something had just passed. She took out her blue feather crossbow, took two steps back, and raised her crossbow to the bottom of the water.

Suddenly, another black shadow flashed, and now Ding Qingyue was sure, there was really something in the water, but the speed of that thing was moving so fast that she couldn't see what it was.

Just as she stared intently at the bottom of the water and tightly held the trigger of the blue feather crossbow, on the roof of the strange building behind her, a silver-gray little monster with two large, two small and four fleshy wings quietly leaned out.

This little thing is only the size of a grinding disc, and it says that it has four meat wings behind it, but in fact, the pair of meat wings on it looks more like ears. This thing is silver-gray all over, looks like a small person, has feet in its right hand, and has a body, but its head is a monster with bared teeth and grinning, it is squatting on the roof, its mouth is flowing with slimy slime, looking at Ding Qingyue, who is facing away from him, and quietly shows a humanized smile.
