What appeared in front of the two of them was a huge pit more than two meters deep.

All around the pit are made of bluestone, and painted black with unknown dye. On the ground, there are seven more golden star patterns, arranged in the shape of the Big Dipper.

On the outermost side of the pit stood thirty-six stout stone pillars, each of which required five or six people to be able to encircle, and the stone pillars were connected to each other with chains dyed blood-red.

The end of the chain finally converges on a high platform in the center of the pit.

In addition to the stone pillars and high platforms, there are countless white bones scattered everywhere in the pit, many of which can be seen at a glance as human bones at all.

"Let's go over and see how it goes. ”

Lu Chen walked over with Yan Meng.

"Brother Lu, what do you think this is?"

Yan Meng suddenly stretched out his hand and pointed not far away, and exclaimed in surprise.

Lu Chen looked over and found the remains of a modern firearm, lying alone outside the giant pit. Maybe because it was too long, this firearm had become a little unrecognizable, but Lu Chen could still tell that it was a Lee-Enfield rifle.

The Lee Enfield rifle is a manual rifle of the British Army from 1896 to 1965, with a large number of variants, and it is also the standard equipment of the British Commonwealth countries, including Canada, New Zealand, Australia, India, Spain, etc.

The reason why Lu Chen was able to identify it was because he had seen an antique rifle with a high degree of similarity in Boss Mo's home.

"How can there be firearms from the British army in the early 20th century?"

Lu Chen's face was full of doubt, and he couldn't understand why there were traces of foreigners here.

"Brother Lu, did you say that the people who died here are all here for the earth dragon marrow?"

Yan Meng looked at the white bones in the pit and asked Lu Chen in a low voice.

"It's not out of the question. ”

Lu Chen nodded, turned his gaze to the stone pillars in the pit, and said in a deep voice: "From the old feng shui master and apprentice before, to the water of the Lechuan River in that lake, to the altar similar to the Mayan pyramid on the other side of the lake, and the huge deep pit in front of you...... Behind all this, there seems to be something hidden that we don't know. ”

After stringing these things together, he vaguely had a bold guess, but there was still some lack of evidence, and it was difficult to come out directly.

Of course, if he's not mistaken, he'll see that soon.

"Brother Lu, there seems to be a pattern on those stone pillars......

At this time, Yan Meng opened his mouth again.

Lu Chen stared at it and found that the thirty-six stone pillars seemed to have some patterns carved on them.

On one of the stone pillars closest to them, a group of humans armed with weapons were carved into battle with a giant serpent that reached the sky, and beneath the giant snake, there were countless human corpses.

On the stone pillar on the other side, it was a different situation, the giant snake that reached the sky was entrenched on the top of the mountain, and at the bottom of the mountain were countless human beings kneeling and worshipping.

Then, the human beings built the altar and carried various sacrifices and placed them at the bottom of the mountain for the serpent to eat......

After reading it briefly, Lu Chen and Yan Meng had already understood most of the contents, and they couldn't help but glance at each other and look at each other.

The scenes carved on these stone pillars are clearly the process of the giant serpent conquering humans and making them worship. No wonder you can meet so many snakes in the cave, it turns out that this is really a snake den, and all the altars are also prepared for the giant snake that reaches the sky.

"I don't know which tribe this conquered by the serpent is, but it seems that none of the people in the southeastern provinces regard snakes as gods and build altars to worship them. ”

Lu Chen's brows were furrowed, in the classics inherited by the Heavenly Mandate Sect, there were indeed tribal peoples who worshiped snakes, but those tribal peoples were all in the southwest, and none of them appeared in the southeastern provinces.

Next, he went around the pit again, and browsed all the carvings on the stone pillars.

Most of the stone pillars are carved with the history of the conquest of the giant snake in the sky, but there are still a few stone pillars that are densely carved with some words.

These characters are completely different from Chinese characters, they look like twisted snakes, and his education is shallow, so he didn't recognize any of them, so he had no choice but to give up.

"It's weird here!"

Seeing that there was nothing new to discover, Lu Chen sighed softly, and then he suddenly came up to Yan Meng's side and asked in a low voice, "Miss Yan, I don't know what you know about Master Wu?"

Yan Meng was stunned by Lu Chen's sudden move, in all these years, in addition to her father and brother, it was the first time she was so close to other members of the opposite sex.

And when Lu Chen was talking, she could even feel the breath exhaled by the other party, this intimate action made her cheeks immediately appear two more blushes, and there was also a hint of shyness between her eyebrows.

"Miss Yan, did you hear my question clearly?"

Seeing that Yan Meng didn't answer for a while, Lu Chen couldn't help but ask again.

"Oh oh oh, I know...... Know ......"

Yan Meng nodded in a panic and continued softly: "My brother and I only met Master Wu under the introduction of a master, and that master told us that Master Wu's mana is strong and can help us find the earth dragon marrow, so we will walk with him. ”

"Before entering the cave, Master Wu told me that the reason why you two brothers and sisters are looking for the earth dragon marrow is to treat your mother's illness, it seems that Master Wu is very familiar with your family?"

Lu Chen asked again.

"Wouldn't we? We didn't know Master Wu before, and we only slowly began to know each other after we got the news of the Earth Dragon Marrow. And it's only in the last three or four months that we've crossed paths more and more. ”

Yan Meng blinked a pair of beautiful eyes and replied without concealment.

After Lu Chen nodded, he said, "You first learned about the existence of the earth dragon marrow from that master, and then through this master, you met Master Wu, is this the whole process?"

"Yes. ”

Yan Meng bowed slightly.

Then the context of this matter has changed a little clearer. ”

Lu Chen smiled faintly and said to himself.

"Brother Lu, have you guessed something, are you doubting Master Wu?"

Yan Meng was very smart, and immediately grasped the point of Lu Chen's questioning just now.

"Actually, it's nothing, it's just a somewhat illusory idea. Whether this idea is true or not, we need to continue to see. ”

Lu Chen didn't say anything, just smiled.

And just as the two of them were talking, a dark shadow suddenly appeared in a corner, looking at the two from afar.
