The spacious underground dark river passage, the further you go inside, the wider the area inside becomes, and after Qin Tian has walked for a full fifteen minutes, he finally came to the destination of his trip, that is, the bottom of the military base of country M that they want to enter, compared to other places, this place is more spacious, the size is almost the size of two football fields, and more importantly, after arriving here, there is no road ahead!

Yes, there is no road, a spacious road, after arriving here, there is no way forward at all, in front of it is a bluestone rock wall, smooth and covered with moss, obviously, under the environment here, after I don't know how many years, this place has long been very ancient, the length of history extends, almost undetectable, and on this bluestone rock wall, there is nothing.

It can be seen that there was obviously a font on the bluestone rock wall in the past, but because the time was too long, the words on it were not clear at all, and it was already very blurry, but it could still be seen that this was similar to the text before the pre-Qin period, of course, Qin Tian was not an expert, and naturally he couldn't be sure whether his conjecture was correct, but he just felt that it should be eight or nine without ten, which was almost the case.

Of course, this is not the only one, in this spacious area the size of two football fields, there are a piece of stone tablets about thirteen meters high and five or six meters wide, these stone tablets are obviously the same as the bluestone rock wall, there is an extremely ancient history, but the difference is that the words on these stone tablets do not belong to the ancient pre-Qin period, more like the pre-Qin period!

"Could it be that there were two groups of people here who did something here?"

Qin Tian wondered, what kind of place is this, why there are such strange stone tablets and bluestone rock walls, what did the ancients do here, why did they leave their mark here, of course, the words on these stone tablets are also the same as the previous bluestone rock walls, they are all unclear, and they can only be roughly distinguished.

Of course, the reason why Qin Tian can distinguish the period, it is naturally very simple, the text before the pre-Qin period, almost all of them are murals related to this word, and after the pre-Qin period, the text has been further improved, of course, it is completely different, which is also why, Qin Tian can distinguish clearly, this is the most basic common sense, as long as any junior high school student can know, although Qin Tian's culture is not too high, but this thing must still be able to distinguish, otherwise, it is too embarrassing!

Circling around this area, Qin Tian was very interested in these bluestone rock walls and stone tablets, because he inexplicably felt that these bluestone rock walls and stone tablets seemed to have an inexplicable attraction to him, but once he got serious, this feeling immediately disappeared again, and he couldn't tell what was going on, but he just had such a feeling in his heart, it was really strange!

Turning around, Qin Tian tried to find that feeling, but he couldn't find it, Qin Tian could only give up helplessly, because he had already walked around the stone tablet and the bluestone rock wall, and this feeling still did not appear, it was obvious that the time had not come, but after such a circle, Qin Tian found one thing, that is, the placement of this stone tablet seemed to be very similar to a large array recorded in the Zhuge Neijing, very similar, but he couldn't be sure that this was that kind of big array, because it seemed to be different, which made Qin Tian's brows frown。

"Looks like there's a lot of secrets buried here!"

Qin Tian didn't dig any further, he went around in a circle, naturally not really to take a look in circles, of course, by the way, to take a look, did the people in this military base do anything to take precautions under this, and after observing this circle, Qin Tian found that there was no modern scientific and technological equipment below, only bluestone rock walls and ancient stone tablets!

Obviously, the people above couldn't guess that there was such a relic down here, otherwise, I'm afraid that the excavation would have already begun, after all, these things, although they can't read the words clearly, if they get it, once the technology is enough, they may get something very important, but in this case, it will also bring Qin Tian and them a problem, that is, how to go up!

Obviously, they are now in the passage of the underground dark river, and there must be a large distance from the military base above, such a distance, it is not that they can be dug up, so Qin Tian did not hesitate, and asked Hu Xue and them to come over as soon as possible, the current situation is naturally for everyone to discuss together, first solve the situation in front of them, as for the bluestone rock wall and stone tablet, we will talk about it later!

When Hu Xue and the others arrived, they were also surprised when they saw this ancient ruin, because it was too strange for such a ruin to appear here, it stands to reason that such a place that is in the depths of the underground river all the year round is impossible for such a ruin, but now they have found one, which is not surprising to them, and they are also full of amazement at the ability of the ancients!

After all, this is the depths of the underground river, even if it is very spacious, but such a boulder, if you want to transport it in, it is not just talking, the manpower and material resources required are absolutely amazing, what age is this ancient ruins, which makes everyone very curious.

However, now is obviously not the time to think about this, Qin Tian interrupted everyone's thoughts, and said his opinion, the top priority is to think about how to solve the problem of entering the military base, as for these bluestone rock walls and stone tablets, after Hu Xue goes back, he will naturally send someone to deal with it, and when the time comes, if there is any news, just ask from her mouth.

"We should be about a kilometer below the military base right now. ”

Hu Xue picked up the instrument and took a look, the direction of the underground dark river channel was unpredictable, it was obvious that this was in a high area, because the air was already very dry.

"In other words, we need to dig a thousand-meter underground tunnel to enter this military base?"

Qin Tian glanced at Hu Xue and asked.

"That's right!"

Hu Xue nodded, of course, their food was sufficient.

"Let's do it. ”

"I'm so tired!"

Jiang Cheng lay sweaty in the excavated passage, completely oblivious to the mud all over his body.
