"This should be it. ”

Ye Ren glanced at the dark swamp, and didn't know what he was thinking, he took out a blue object from the pocket tied behind him and looked at it, and then held it in his hand, the fluorescent blue soft light gave Ye Ren a very familiar feeling.

This thing was found by Ye Ren in the abdomen of the giant crocodile, it should be left by the unlucky cannibal chief or a wizard or something, although the cannibal chief has been chewed and digested by the giant crocodile, but this blue thing has been stored in its stomach, until Ye Ren shared all the internal organs of the giant crocodile with a group of bugs, this thing has been rediscovered.

"I always feel that this thing is very familiar..."Ye Ren felt the familiar feeling in his hand, and couldn't help but think of the stone pattern Rubik's Cube that he didn't bring with him this time, and the small stone pillar that emitted blue light inside the Rubik's Cube seemed to be the same material as this.

It's just that the blue glowing stone in front of him is much smaller than the small stone stick, not as big as a fingernail, and the edges of the edges are very sharp and sharp, like some kind of fragment.

"Let's go down and have a look. ”

After thinking about it for a while, Ye Ren still planned to go to the bottom of the swamp to search around first, to see if the so-called ruins were around here, because that amber emperor crocodile really didn't look like a guy on the earth, if that ancient ruin existed, then this giant crocodile was likely to have a certain connection with that place, and Ye Ren didn't find any clues about the ruins in other places, but there was this strange creature here, so it was very likely that this so-called ruins did not exist on the surface. It is very likely that it was hidden underwater, or even buried in the mud.

Just do it. Ye Ren did not shrink his body either, and controlled his muscles to close his ear canal and nostrils. Then he jumped into the water with a pop and splashed a lot of water.

The water in the swamp itself was very muddy, filled with bacteria, plankton, mud, and rotting leaves, all of which stirred together like a heavy black veil, making it impossible to even see the surroundings.

And, coupled with the fact that it is dark in itself, the trees in the Amazon jungle compete for sunlight and rain. The canopy of the trees was unusually dense and developed, and the faint moonlight could not be projected from it at all, making it seem that the entire swamp was even more pitch black, and after Ye Ren jumped in, he suddenly felt that the surroundings were plunged into darkness, as if he couldn't see his five fingers.

However, Ye Ren was not afraid of this, but the muscles on his body shook slightly, and a faint electric current instantly spread in all directions.

Inductance.

After ascending to the third-level electric eel electromuscle, Ye Ren's sense of a certain tissue generated in his brain that was used to sense and manipulate electrical currents became clearer and clearer. And the operation of the current is also more and more handy, compared to the previous only squeezing muscle power into electricity, now Ye Ren feels that he seems to be able to use the current to do more things, such as now using the current instead of his eyes to probe the surrounding turbid environment...

When the vision is confused. The inductance is very wonderful, although Ye Ren can't say this feeling specifically, but it seems to be similar to the ultrasonic pathfinding of bats. It's just that Ye Ren replaced the sound wave with an electric current.

The range of inductance is not particularly large, based on Ye Ren's current control zhì Cheng dù. It can probably only sense about ten meters around, which means that the range that Ye Ren can detect is to take himself as the center of the circle. A sphere with a radius of ten meters, it is not that Ye Ren's power strength is insufficient, but the problem of controlling the force, Ye Ren has just risen to the third level of electrical muscles, and he is still very unfamiliar with the sudden increase in various fancy power control methods, and he cannot use them particularly perfectly, so he must have a process of slowly getting acquainted.

Fortunately, the swamp was not very large, and Ye Ren swam in the water for less than three minutes before he discovered a hidden cave under the swamp through guò induction.

"Huh?"

The appearance of the cave immediately attracted Ye Ren's attention, and after floating to the surface of the water to change his breath, Ye Ren dived underwater again and slowly swam towards the hidden cave entrance.

The bottom of the swamp was completely covered with a thick layer of mud and dead branches and rotting leaves, mixed with the bones of some unlucky beasts, but this cave was an exception, the whole cave was like the shape of a funnel, and the more you went inside, the narrower it became, so that Ye Ren had to hide his self-eating ability, and let his body return to its original size before he could burrow into the cave.

After entering the cave, Ye Ren slowly walked forward while exerting his electric inductance to the limit, sensing if there was an unknown beast in front of him that would suddenly attack him.

The cave is all made of some kind of hard rock, which looks solid, but the traces of artificial excavation are obvious, Ye Ren slowly moved inside, about two minutes or so, just when Ye Ren hesitated whether to go back, his inductance clearly felt that there seemed to be an exit ahead, so he quickly swam towards the exit.

"Whoa!"

Ye Ren stretched his head out of the exit, and did not breathe directly, but first pinched the blue fragment in his hand, and carefully looked at the surrounding environment with the help of the faint light.

This is a place similar to artificial construction, not far in front of me is a stone platform, which can stand up from the water, and there is a semicircular stone candlestick on each side, I don't know if it is because of the age that has lost its light, and not far from the stone platform, a stone gate that is almost more than three meters high is standing there quietly.

Ye Ren took a tentative breath, and after staying for a while, he found that there was nothing abnormal, so he breathed with confidence and slowly climbed up from the water, it seems that there is either a vent nearby, or something can produce oxygen.

After walking to the stone platform, with the help of the faint blue light in his hand, Ye Ren slowly walked towards the gate, because he didn't bring the Rubik's Cube and the key this time, and Ye Ren didn't plan to open the door, just wanted to see what this ruin looked like and see the real face.

But when Ye Ren really walked in front of the door, he was suddenly stunned.

"Huh?"

Ye Ren looked at the door with some surprise, this stone door was carved with many exquisite thorn patterns, and it was also inlaid with two very beautiful rubies, the overall look was very beautiful, but what surprised Ye Ren was naturally not how exquisite this door was, but that at this moment, instead of being closed, the door was slightly exposed, which looked like it was not closed tightly, and the cracks in the door were full of endless darkness, and a breath that made Ye Ren a little creepy slowly escaped from inside......

[The light is too dim, and it's a bit troublesome.] Ye Renyi frowned, slowly took two steps back, and then began to look around, trying to find some items that could be ignited.

After looking around, Ye Ren couldn't find anything like a tree branch, so he had no choice but to collect some dry moss nearby, as well as some black paste left in the two wall lamps, stuffed them all into the hemp bag behind him, and then sparked them with an electric spark.

Fortunately, the hemp bag is soaked in oil, otherwise it would not have burned so lightly after being wet with water at the moment.

Due to the incendiary material, a flame quickly jumped up from the sack, and the warm orange light illuminated the surroundings very clearly, Ye Ren held the slowly burning sack while very cautiously pushed open the stone door.

"Squeak... Ga ......"

With a somewhat uncomfortable friction sound echoing inside this empty cave, the stone door was slowly pushed open by Ye Ren.

Ye Ren didn't go in, but first threw the burning sack into the space inside the stone door with a little force, and suddenly the orange firelight lit up a space inside the door, and seeing that nothing happened, Ye Ren walked in very cautiously.

As soon as he entered the inside of the grotto, Ye Ren felt a chill, as if his scalp was faintly numb, and immediately became more vigilant, looked around cautiously, and found that there was no movement before he calmed down a little.

"This place is so weird. Frowning and muttering to himself, Ye Ren came to the side of the fire and began to look at the surroundings.

The interior of this grotto is not as big as Ye Ren imagined, only about 100 square meters, it is a completely enclosed circular space, there is almost nothing in it, it seems very empty, there seem to be some murals at the top of the grotto, but I don't know if it is because the age is too old, these murals have been weathered very strictly, I can't see what is painted, there seem to be some crystal fragments on the ground in the center of the grotto, and there are some dark brown traces hidden on the ground around it, and there are almost nothing else, which makes Ye Ren feel very disappointed。

"It's ......"

Ye Ren stepped forward with some curiosity, squatted on the ground and examined it carefully, scraped off a small layer of dark brown marks with his sharp fingertips, and then sniffed it, his face changed slightly: "Bloodstains?"

Did something happen here that you didn't expect? Or did someone come here before you?

At this moment, Ye Ren's mind was almost full of all kinds of questions, the Rubik's Cube and the key were clearly here, who could open the door and enter here? Or did someone use the Rubik's Cube to come here before he found the Rubik's Cube? But what about the fragment in his hand that was made of the same material as the blue stone pillar key?

"What is this?"

After Ye Ren found the bloodstains, he glanced at the crystal fragments on the side, which looked a bit like the traces left by some kind of crystal breaking, but among them, Ye Ren found a black sheet that looked like the size of a sesame seed, so he frowned slightly and reached out to pick it up.
