The smell of sulfur is everywhere, and the walls are unevenly covered with rocks and sulfur.

"Seven, these holes don't look like they've been dug out." Zhang Erhe has a suspicious color, the whole stone cave has no traces of excavation at all, the water seeps above the mountain wall, and slowly converges into a half-finger-wide stream under their bodies, lying on it, the clothes are wet, quite uncomfortable, illuminated by a miner's lamp, this low cave seems to be quite far away.

"That's true, this hole was not dug by the miners, it should be a hole left over from a sulphur mine a long time ago, and from here, you can see the pit." No. 7 explained, but Liu Yuan's eyes were cold and he saw a hint of strangeness.

"Seven, who are you listening to?" Liu Yuan couldn't help asking, very puzzled that No. 7 had such a mistake.

"Professor Gao." No. 7 said without looking back, in fact, because the cave wall was too short, he couldn't come back.

"And what do you think?" Liu Yuan said with interest, lying in the cave, and did not slow down the trip because of their conversation.

Seven laughed twice, pulled out a small piece of sulfur stone from the cave wall, looked at it, and said, "Whatever you think, I'll think." ”

Indeed, in such a deep underground world, who would want to bypass the coal seams for the sake of this sulfur? And at that time, this coal mine should still be closed, and where did it come from here? Anyone with no problem with their brains can usually think of this question, but the absurd statement comes from the mouth of a respected professor, which is a bit unreasonable.

"Who the hell is that Professor Gao? It can't be an idiot, right? Zhang Erhe also muttered, this hole is obviously a thief hole, and it is dug from the inside out, and people who have been in contact with this line can basically see it.

"Don't say this kind of thing anymore, Professor Gao is a celebrity in the archaeological field, he has participated in the excavation of the Qin Emperor and Han Tombs, and he is a senior in this industry.

"Uncle Zhang, don't talk nonsense anymore, don't forget the identities of the two of us, the people who can be here will not be simple masters." Liu Yuan heard some fame, and tonight's tomb buried deep underground is by no means simple, and looking at the dense sulfur veins around it, it is even more curious.

Zhang Erhe pouted after him, and no longer squeaked, this low hole was only 100 meters deep, and when he was close to the entrance, he could hear the sound of the water flowing inside, occasionally mixed with the sound of shouting, thinking that it was the archaeologists who had gone deep into the ground earlier.

Out of the low hole, the eyes suddenly opened up, the lights shone, and the rumbling sound of the generator also made them clearly understand that they had finally arrived at their destination.

In addition to the busy people around, there were three or four people who looked like leaders, and when they saw the three of them coming out of the hole, someone stepped forward in an instant.

"What about Professor Gao?" Seven asked, the purpose of their trip was not to talk to these people, and in this huge space, there must be as many as thirty or forty people, to say the least.

"It's still on the other side of the pit, I'll take you there." The man didn't talk nonsense, walked forward, said hello to the people who looked like leaders, and walked towards the inside of the cave without staying too long.

"Wait!" Just as the four of them were about to leave, several people who looked like leaders stopped talking instantly, and one of them stepped forward, dressed in a mining suit, short and fat in stature, and stared at Liu Yuan and the others with two eyes tightly.

"Who are they?" At this time, the other three also came over and said, "Lao Xu, don't be so surprised, these two were invited by Staff Officer Li, and they have already greeted each other this afternoon." ”

"Li Ru?" The short and fat man stared at Liu Yuan and the two of them tightly, went around in a circle, and said disdainfully: "Is Li Ru blind?" Such a little hairy child, the hair hasn't grown together, right? What does it mean to let him come? Don't think it's messy enough, isn't it? "The short and fat man's name is Xu Zhongguo, and the people who have a good relationship with him call him Xu Zhongguo, and he is also the commander-in-chief of this excavation.

In fact, everyone has no idea about Liu Yuan's ability, after all, the age is there, even the most respected professor Gao in China is at a loss in the face of this excavation, let alone him?

"Master Xu, you should have heard of the name of the Buddha of the Family Master and the Earth Sect, right? He was specially invited by the family teacher to help this time, and only he could find the tomb. Seeing that the situation was not right, No. 7 hurriedly stepped forward to explain, this Xu Zhongguo is not a master to be messed with, although he is only a division commander, he is a violent temper, especially this time as the commander-in-chief, in a month, there has been no progress, it is conceivable that he is depressed at this time, if he is entangled, it will be a delay.

"Oh? I remember you, you were the captain of the special forces of the 213th operation, number seven, right? How? A few days ago, I slapped my face here, and I found a little hairy kid to tease me, right? I'm a vegetarian! Xu Zhongguo stepped forward and slapped No. 7 in the face, and the people who were busy around him also turned their faces, this sudden situation was indeed unexpected.

"Look at what! Work! What kind of bullshit Buddha is just a tomb robber, and he dares to say it on the table? How? Not convinced? The stocky man exclaimed angrily and slapped Seven in the face again.

"Lao Xu, what are you doing here? Will you try it? What's the use of having such a big temper? A person next to him glanced at No. 7, this Xu Zhongguo seemed to have taken the wrong medicine today, and he had not had a good face since he saw Liu Yuan and the two.

"Alright, Seven, take them over, remember, tonight, you must have an explanation!" After stabilizing Xu Zhongguo, the man hurriedly said, for fear that Lao Xu would be in trouble again.

"Yes!" No. 7 stood up expressionlessly, bowed, and walked deep into the cave under the guidance of the person in front of him.

Liu Yuan followed closely, constantly thinking about the conversation between the two of them just now, as if everything was logical, and always felt that something was wrong, seeing that No. 7 didn't have too many expressions, he had to dispel this thought, and Zhang Erhe was much more straightforward, stepped forward and patted No. 7's shoulder, quite sympathetic, no matter what, No. 7 was also because the two of them were beaten, even if he didn't say it, Zhang Erhe could understand his mood at this time.

In the ravine under their feet, there is a river more than one meter wide, flowing slowly from top to bottom, and on the surrounding mountain walls, stalactites of various colors stand up, and under the light background, it is very beautiful.

"Seventh, just now..."Crossing the river from the wooden bridge, the person who led the way went back, and Liu Yuan couldn't help but wonder in his heart, and whispered, but before the words came out, he was stopped by Seven, so he had to swallow the words that came to his mouth, in this place, it is better to talk less.
