"How can this cave be so deep?"

Yan Tong frowned deeply, looked at the swarthy cave, and asked Master Wu with doubts.

"This cave is not only deep, but also narrow, if you really encounter any danger halfway, I'm afraid you won't have time to react!"

Yan Meng nodded, and said with a solemn expression.

Master Wu sighed softly, no wonder the old feng shui master and his little apprentice at that time were not able to come up again, in such an environment, once they encountered any beasts and beasts, they would definitely die.

Just when the atmosphere was a little quiet, Yan Meng asked again, "Is there enough oxygen in this cave, are there any other harmful gases?"

When the bodyguard who was in charge of dropping the environmental detector heard this, he quickly looked down at the data and replied: "The oxygen concentration is slightly higher, the humidity is higher, the temperature is only about 17 degrees, and no harmful gases have been detected." ”

"That's good news. ”

Yan Tong smiled, if there were any more harmful gases in the cave, then how could they go down? Are they wearing gas masks one by one? If they encounter danger like that, I'm afraid the reaction speed will become slower, right?

"Let's put the surveillance camera down, and see if there's any danger in the process of going down the hole." If there is danger, the plan is suspended and the protective clothing arrives before entering. ”

Yan Meng looked at Master Wu and his elder brother and asked for their opinions.

"Okay, that's the only way to do it first. ”

Yan Tong and Master Wu both nodded and agreed, after all, everyone can't joke with human life, right?

Under Yan Meng's instructions, several bodyguards took out a large number of parts from their backpacks, and after a while, they assembled a shooting robot, with a crawler below and a camera gimbal above, which can stably shoot the picture in the cave.

The camera robot slid down the safety rope that had just arrived at the bottom of the cave and slid down little by little.

The video remote control in the hand of a bodyguard shows the scenes captured by the robot, and everyone gathers around them, frowning and taking a closer look.

The topography of this dragon's head cave is very interesting, like an upside-down funnel, and the area in front of it is nearly 300 meters, which is so narrow that it can only accommodate one person to pass through, and it is not enough to be a little fatter. Further down, it suddenly opens up, and in terms of width, it can almost accommodate ten people passing side by side.

After arriving at the bottom of the cave, the camera robot slowly moved forward under the control of the bodyguard, and the environment at the bottom of the cave was gradually presented in front of everyone's eyes.

"Wait, what is this?"

Lu Chen suddenly stopped the bodyguard who was controlling the robot and pointed to the upper right corner.

When the bodyguard heard this, he turned the camera very cooperatively, and when he saw clearly what Lu Chen was pointing at, everyone suddenly gasped. I saw a corpse lying on the side of the mountain wall, but due to the time, the corpse had already decomposed into white bones.

"Whose corpse is this? Is it the little apprentice's, or is it the old feng shui master's?"

Yan Tong asked in surprise.

According to the notes of the eldest apprentice, the junior apprentice should have been only thirteen or fourteen years old at the time, and this corpse was taller and had thicker bones, so it was very likely that the old feng shui master was the old feng shui master. ”

Lu Chen observed for a while, then replied in a deep voice.

When everyone heard this, they all nodded, the bones of adults and teenagers are very different, as long as you look at the development of the bones, you can determine.

"It's strange, according to the big apprentice, didn't the old feng shui master suddenly encounter some kind of danger? Why did his body suddenly run away a hundred meters away from the entrance of the cave? And the old feng shui master's body is here, so where did the body of the little apprentice who had encountered an accident before go?"

Yan Meng frowned slightly, and said with doubts.

Lu Chen nodded sympathetically, feeling that this was full of weirdness and strangeness.

According to the notes of the big apprentice, the old feng shui master and the little apprentice both encountered danger in the cave and unfortunately died. But looking at the bones of the old feng shui master, there are no extra scars at all, and they are still lying on the ground, if they really meet some fierce beasts and beasts, when they are bitten and eaten, they will definitely leave traces on the bones.

The more Lu Chen thought about it, the more he felt that something was wrong, but he couldn't think of anything specifically wrong.

At this moment, the camera robot continued to move forward, and finally stopped in front of a dark lake.

"Damn, why did this suddenly appear a lake? Could it be an underground lake?"

Yan Tong's eyes widened, full of doubts.

According to the results of the shooting, this dark lake is at least three or four meters wide, and the robot cannot cross it at all. What's more, this dark lake seems to be completely different from other underground lakes, the water is a little black, and it is impossible to see how deep the bottom of the lake is.

On the opposite side of the dark lake, a stone platform about two or three meters high can be faintly seen, but the specific situation is too far away to see clearly.

"Based on what we've photographed, it doesn't seem like there's much danger in this dragon's head hole......"

The Yan siblings and bodyguards were standing together, discussing how to enter the underground cave.

And Lu Chen asked for a video remote control, controlled the camera robot, and walked around the cave.

At this time, Master Wu walked over and said with a smile: "Mr. Lu, do you think that if there is really an earth dragon marrow in this dragon head cave, then where should it be?"

"If there were no other mechanisms in the cave, then the earth dragon marrow should be in that stone platform. ”

Lu Chen controlled the robot to the dark lake and pointed to the stone platform on the other side of the lake.

"Indeed!"

Master Wu nodded, and then continued: "Just now, the camera robot took a turn in the cave, and he didn't find anything special, only that stone platform was a little special. ”

Lu Chen smiled faintly, looked directly at the other party, and said in a low voice, "Master Wu wants me to go down with everyone?"

When Master Wu heard this, a look of surprise appeared on his face, and he said helplessly: "I didn't expect to be seen by Mr. Lu." I do think so, in fact, in our feng shui, we also pay attention to the cycle of cause and effect, isn't it? This earth dragon marrow is the essence of the dragon veins that have been nurtured for thousands of years, and it is not something that mortals can obtain. ”

"And Mr. Lu, you are different from us, when you just found the dragon vein, you were nourished by the dragon vein's qi, which can be regarded as being recognized by the dragon vein. This is enough to see that you are a person of great opportunity and good fortune, so I think that if you go down the cave with us, we will definitely help us find the essence of the dragon. ”

After hearing this, Lu Chen did not give an answer immediately, but frowned and thought about it.

In fact, to be honest, before this, he was very curious about the dragon's head acupoint, and he also had a little idea of going down the cave with everyone, but now, he is more confused than curious.
