Seeing that Lu Chen still had this kung fu, everyone immediately began to retreat back about a hundred meters, while Lu Chen retreated to a place thirty meters away from the stone wall, and if it was farther, he would not be much sure.

After five consecutive attempts, on the sixth time, the stone that Lu Chen threw with all his might finally hit the cobblestone mechanism.

"Boom ......"

There was a loud noise, and the smooth mirror-like stone wall actually began to move, and in the area above the cobblestone mechanism, pieces of mountain stones extended outward, and they were closely attached to each other, forming a mountain stone bridge, leading directly to the opposite side of the dark lake.

"Great!"

Yan Tong looked excited, and hurriedly led everyone back to the dark lake.

It's just that when everyone used a strong flashlight to shine on the stone wall again, they were surprised to find that the stone wall, which was originally as smooth as a mirror, was full of blood-red strange words and strange patterns that made people scratch their heads.

"Mr. Lu, Master Wu, how do I look at these patterns, they look like a big snake?"

Yan Meng stared at the pattern on the stone wall for a while, then his pretty face turned pale and he exclaimed.

When everyone heard this, they stood where she was and looked at the stone wall, and sure enough, those strange patterns and words constituted a big snake lying on its back. Moreover, there are no scales on the body of this big snake, and the whole body is covered with bloodshots, which is dense, which makes people can't help but feel afraid.

Lu Chen walked to the stone wall, stretched out his hand and touched the words and patterns, and said in a deep voice: "These things should have been drawn by someone with special materials, and the dark lake in front of us is very likely to be artificially designed." ”

When he first saw this dark lake composed of the waters of the Lechuan River, he already had this idea in his heart, and now the change in the stone wall made him even more convinced.

"Artificial?"

After hearing this, Master Wu's eyebrows furrowed slightly, and then he continued to ask: "What does Mr. Lu mean is that there are actually people who have already been here for a long time? And these people have also left words and patterns on the stone wall, and specially made such a lake of Lechuan River?"

Lu Chen nodded and said softly, "Those people should have come here a very long time ago, at least before that old feng shui master." ”

"I think so too. ”

At this time, Yan Meng also smiled and said: "If those people who designed the dark lake are later than the old feng shui master, then how can they ignore the bones of the old feng shui master?

"That's right, the bones of the old feng shui master are there, and it's impossible for anyone to ignore them, right?"

Yan Tong suddenly realized.

Everyone else had the same idea, and if they were the ones who built the lake, they wouldn't like to have the bones of a dead man next to it. Although there are no ghosts, it is too mad to get along with a white skeleton day and night!

Master Wu seemed to accept this statement, staring at the blood-yellow lake, and couldn't help but exclaim: "I don't know who designed and built this dark lake, it's unbelievable to be able to find such a big lake of Lechuan River." ”

At the same time, Lu Chen was observing the words on the stone wall, although he read it very seriously, but unfortunately, he only had a junior high school education, and he didn't have the habit of studying any ancient Chinese characters, so he didn't recognize a single word when he read it.

As for those patterns, he was even more confused, anyway, he had also read the inheritance books of the Heavenly Mandate Sect, but there were no clues at all.

However, it is not that there is nothing to gain, at least he can see that these words and patterns all show a rich and simple atmosphere, which seems to be very old, and also contains some very special meanings.

"Master Wu, Mr. Lu, can we go directly to the other side now and see if there is any earth dragon marrow?"

Yan Meng saw that Lu Chen and the others were motionless, and couldn't help but speak.

Interrupted by her like this, Lu Chen and Master Wu immediately came back to their senses, and couldn't help but look at each other, secretly sighing at the mysterious charm of these words and patterns, and the two of them were unconsciously attracted to it.

"Let's go. ”

Lu Chen shook his head, threw out the messy thoughts just now, and then stepped onto the stone bridge and walked cautiously all the way to the other side of the lake.

In the past, when we were across the dark lake, we could only vaguely see a stone platform, but now that we are on the other side of the lake, the scale and shape of this stone platform are more clearly displayed in front of everyone.

To everyone's surprise, this stone platform is actually in the shape of a pyramid, which is formed by the accumulation of large bluestones, and there is a stone staircase in the center, leading to the top of the stone platform.

"How do I think I've seen something like this somewhere?"

Yan Meng frowned slightly, and after thinking carefully for a few seconds, he suddenly said loudly: "Isn't this the Mayan pyramid in South America?"

"Really, I said how did it look so familiar. ”

Yan Tong nodded hurriedly.

The Mayan pyramids are the most famous structures after the Egyptian pyramids.

Compared to the pyramids of Egypt, the Mayan pyramids are slightly shorter and are also made of huge stones, but the whole pyramid is grayish-white, not completely cone-shaped, and there is a temple dedicated to the gods at the very top.

The stone platform in front of everyone is simply a miniature version of the Mayan pyramid, except that the top is not a temple, but an altar.

The existence of the dark lake and the stone platform all show that there have been human activities here, and it is still unknown whether the earth dragon marrow, which is the treasure of the earth, can exist once it is discovered.

After all, a strange thing like the earth dragon marrow that can prolong life and cure all kinds of diseases, as long as it can be recognized, there will be no reason to let it go.

"Let's go, whether the earth dragon marrow still exists, we can only go up to the stone platform to see the situation. ”

Lu Chen didn't have much confidence in his heart, so he could only look at it step by step.

He walked in the front alone, but behind him was no longer Master Wu, but Yan Meng.

Yan Meng also seemed to have expected that the chance of the existence of the earth dragon marrow was very small, so he seemed a little anxious, and his steps were hurried and scattered.

The entire stone platform was almost ten meters high, the stone stairs went straight up, and it didn't take a few minutes for Lu Chen and Yan Meng to reach the top floor.

At this moment, Yan Meng's breathing suddenly became short, her face was slightly pale, she forcibly dragged her slightly trembling body, and walked to the altar at the top step by step.

"Miss Yan...... Miss Yan......"

Seeing this, Lu Chen couldn't help frowning, and hurriedly stepped forward to grab Yan Meng and stop her from moving forward. At this time, Yan Meng's expression was sluggish, and his eyes were full of despair.

"Miss Yan, are you okay?"

Lu Chen tried to wake her up, but after screaming several times, she still looked like a confused person. In the end, Lu Chen had an idea, unscrewed the kettle he was carrying, and splashed the water inside at her.
