After a while, the people in the cave came out one after another.

Mr. Liao looked at him strangely.

When he saw that everyone came out, Wang Shaoyi first took a long breath, then there was a look of confusion on his face, and finally his frowning brows stretched out and smiled slightly.

His ever-changing expression stunned the others.

Mr. Liao walked around him, his eyes swept over him, and finally said a little puzzled: "Strange? You're not possessed by anything! ”

Wang Shaoyi "forehead" for a while only to find that Mr. Liao was ridiculing him, he ignored Mr. Liao, but beckoned others to follow him, and after a while, he arrived at the place where he was bumped into before.

He drew a circle with his hand, pointed to the vast plant, and said, "Do you know these things?" ”

Following the direction of his finger, Zhao Jie squatted down and looked at it a few times, then gently touched the surface a few times with his hand, and asked tentatively: "Ba Mao?" But he frowned, and then said, "It doesn't seem to be." ”

Zhao Jie's strange words made the rest of the people confused, and they also followed around to take a look, and talked about it for a while, but in the end they all shook their heads, obviously they didn't know the plant in front of them that looked like a barmao.

Wang Shaoyi took out the Luoyang shovel from his bag, found a plant, and dug hard at the bottom for a while, before digging some roots next to a plant, those roots looked very thick and big, he pointed and said: "You shouldn't have seen this thing, I also saw it by chance in "Encyclopedia Grass Planting". This thing is called vetiver. ”

Encyclopedia grass planting? Vetiver? Everyone else showed puzzled expressions, thinking that they hadn't read the book Encyclopedia Planting, and they couldn't talk about this vetiver anymore.

Wang Shaoyi saw their puzzled expressions, so he explained: "This vetiver is a plant that looks very much like a barberry, mostly lives in tropical areas, and is a plant with a very developed root system. Yes, it's these thick roots, they can go up to three meters deep into the ground, and this plant is super adaptable, and in some places in the south it is regarded as a soil-fixing thing. ”

"Wang Shaoyi, what you said is not right, right?" Just as he finished speaking, Wu Liancheng immediately took over, and she said teasingly, "The thing you said grows in the tropics, but you said that this thing in front of you is, isn't it a contradiction?" Could it be that our car is sitting in the opposite direction, and now this is Yunnan? ”

Wang Shaoyi was slightly stunned, and saw Wu Liancheng's muttering mouth, presumably because of the previous bickering, he did not refute her, but said meaningfully: "It can not be a contradiction." ”

"Huh?" When Wu Liancheng heard what he said, he frowned, looked at the vetiver with fixed eyes, thoughtfully, and said tentatively after a while: "You mean that someone planted something here?" ”

"Smart, it's good to have a father who is a police officer, just get a little bit of it." Wang Shaoyi praised Wu Liancheng from the bottom of his heart.

This time, it made her blush, and she was a little embarrassed.

Wang Shaoyi then expressed his doubts. It turned out that he was a little suspicious of Wang Taifeng's "inverted bucket", Wang Mengmeng said before that her grandfather collapsed when he came to dig a hole, but if that is the case, it will contradict the vetiver in front of him, where there is this kind of grass, the whole piece of soil should be relatively firm, and it will not collapse easily.

"Could it be that it wasn't a hole dug here, but somewhere else, like the hillside or the top of the mountain?" Wu Liancheng asked again.

"No, it won't. Even if it's not here, it's not too far away. Wang Mengmeng interjected a sentence at this time and said, "This Ming Dynasty tomb is built along the hillside in front of me, I also used Feng Shui to explore it just now, the top of the mountain is the top of the tomb, and the general choice to dig the thief hole is at the bottom of the mountain, no one will choose to dig straight down, and"

She paused for a while, looked at the place where they had dug the cave before, and then continued: "I also saw this thing just now, I dug a few shovels, and it was difficult to go down, so I ran to the place in front of us, but the vetiver grass that Shaoyi said may have been planted later, after all, nearly a hundred years have passed." ”

After Wang Mengmeng finished speaking, Wang Shaoyi lowered his head and thought for a while, then suddenly raised his head again, pointed to the forest on the top of the mountain and said: "Actually, it's not just this, you can look at that forest again." ”

Following the direction of Wang Shaoyi's finger, they looked over there again, and it was a coincidence that at this time, there happened to be another gust of mountain wind, revealing the full green fruit under the leaves.

"Jujube Tree?!" Mr. Liao, who had not spoken, suddenly screamed. In fact, the jujube tree is the easiest plant to identify, but anyone who grew up in that era, when he was a child, he and his friends took bamboo poles to steal dates to eat, which was a common thing.

Wang Shaoyi nodded, and was just about to praise Mr. Liao for a few words, but he didn't expect to cough up with a "cough" that was choked by his next sentence, and he almost didn't change it in one breath.

I saw that Mr. Liao looked greedy and said, "Shaoyi, are you telling us that we can eat dates?" Speaking of which, this jujube ripens quite early, but I don't know if it's sour or not. ”

Wang Shaoyi shook Mr. Liao's big eyes, and he was speechless for a while.

"I also saw that jujube forest just now." Zhao Jie said kindly.

After Zhao Jie finished speaking, Wang Shaoyi also eased up, and then he said to the others: "Have you noticed, these jujube trees seem to be at least nearly ten meters high, they should be adult jujube trees, such a big jujube tree, the root system must be very developed, at least it can reach fifteen or sixteen meters underground." ”

"What does that mean?" Mr. Liao still asked puzzled.

"Don't you think it's unreasonable to have such a big jujube tree above the ancient tomb?" Wang Shaoyi said and looked at the top of the mountain, "These jujube trees, growing in this kind of place, unless their roots can bypass the ancient tomb, or grow into the ancient tomb." But it's impossible! The root system of an adult jujube tree is very thick, and it is impossible to grow around it. It is even more impossible to grow into the ancient tomb, the blue bricks of the Ming Dynasty tomb have been filled with rammed earth, and it is impossible for plants to grow into the high-density filling. ”

"You mean to say that my grandfather is a liar? But is there a need for this? Wang Mengmeng heard Wang Shaoyi seem to be suspicious of what she said, and said with some complaint between her words.

"Ahem~" Wang Shaoyi only noticed that the tone of his speech was a little inappropriate at this time, coughed a few times awkwardly, and then said: "It can't be said that it is wrong, it may be that the light in the cemetery was relatively dim at that time, and it is possible to make a mistake in judgment, but in any case, this vetiver and the jujube forest all indicate one thing, that is, the location of this tomb may be much deeper than we imagined, according to the algorithm just now, it should be nearly twenty meters." ”

When he finished speaking, Wu Liancheng suddenly interjected: "After listening to you, I always feel weird, before Mengmeng said that the robbery hole should be dug from the bottom of the mountain, so there should be no cemetery under the bottom of the mountain, and if it was blown up at that time, how could it go to the tomb, and so a large amount of soil will definitely bury the tomb, right?" ”

Wang Shaoyi listened to the side without making a sound, but suddenly squatted, found a branch from the side, and drew it in a clearing.

Wang Mengmeng saw Wu Liancheng and doubted what her grandfather dictated, her face was not particularly good, but listening to what Wu Liancheng said, it seemed to be a contradictory thing, and she could only be so aggrieved that she didn't speak.

For a moment, the col was quiet again, and even some of the bird calls that had begun to be sporadic were gone.

"Come and see." After being quiet for a while, Wang Shaoyi suddenly said to the others.

The others gathered around him, and only then did they see what he had drawn on the ground.

It was a somewhat strange figure, first a diagonal line, almost 30 degrees or so from the horizontal plane, marked with a number "1" on the side, and a semicircle with an opening facing down at the bottom right, and a line was also drawn diagonally between the side of the semicircle and the "1" line, with a "1" line at one end and a large arc at the other end, and a number "2" was marked on its side.

This strange graphic is very puzzling to look at.;
