Fu Ying suddenly stopped, looked at Yang Hao with a sideways face and said, "Brother Yang, I don't think we have to move forward." ”

"What do you mean?" Yang Hao wondered.

"It's already on the ground. Fu Ying stared at her feet and said.

Yang Hao also looked at his feet: "You mean that the ancient tomb is right down here?"

Fu Ying nodded and said, "Yes." ”

"What? The ancient tomb is down here?" Heng Qi, Xie Ke, Huang Ranran, and others, who were waving wooden sticks and driving away snakes, stayed there together, like a "freeze frame" in a movie. And after Huang Ran came back to his senses, a pair of thieves released a fine light again, and even saliva flowed, it seemed that he was dreaming of making a fortune again.

"Brothers, I'm going to probe it now to see if the dungeon is right down here?" Fu Ying said, taking out a delicate and small metal instrument from her backpack, more than a foot long, with a smooth and pointed head, spiral-shaped, a bit like the drill flower used by carpenters to drill wood.

Everyone wondered, "What is this?"

Fu Ying replied: "Now that science and technology are developed, I don't want to use Luoyang shovel, so I will use this 'drill gopher' instead." ”

Huang ran and gaged and said: "I remember that the drill rat is Lu Fang, and the gopher is Han Zhang, right?"

Heng Qi gave Huang Ran a roll of his eyes and said, "Huang Ranran, you are simply a little out of place!"

Xie Keze stared at the "drill gopher" that Fu Ying was holding and said, "What's the use of this?"

Fu Ying replied: "It plays the role of the Luoyang shovel, and at the same time remote sensing and detection. As she spoke, she flicked a switch, and the thing flew out of her hand, and then fell down, into the dirt, and disappeared in the blink of an eye, except for a small hole in the mouth of a teacup, not even a little dirt was turned out, like the legendary "earth escape".

Before everyone came back to their senses, Fu Ying took out another thing from her body, but it was a palm-sized screen. Fu Ying flicked the switch, and the screen suddenly lit up, and then an image of activity appeared, as if a photographer was holding a camera and moving forward. But the picture is a little incomprehensible. It's like a strange pattern with many gray honeycombs spliced together.

Fu Ying explained: "This is the picture transmitted back by the 'drill gopher', which can be used for light image shooting in three modes: visible, infrared and low-light, and can also be used for blind shooting in ion sensing mode. Now the image it comes back with is a blind shot. The blind shooting technique has not been mastered by any country to date. ”

Yang Hao said thoughtfully: "Your words remind me of some past events...... We seem to have had this technique three years ago, when two girls learned it from some alien from outer space. ”

"Are those two witch friends you were talking about?" Fu Ying asked.

Yang Hao nodded: "Yes, it's ...... them"

He wanted to recall this past, but whenever he wanted to recall, his head would hurt, and at the same time, his memory would be like a broken chain, and he couldn't catch it well.

"Brother Yang, don't force some things if you can't think of them for a while, my little sister said, when I rescue my father, I will definitely help you find the three-headed snake and cure your condition. Fu Ying bit her lip and said.

"What do these pictures mean?" Yang Hao finally stopped thinking about those things, and his attention refocused on the screen in Fu Ying's hand.

Fu Ying said: "These are all meaningless soil layers and rocks, and the area of sight distance is not large, for example, there is not much difference from the hole drilled by a frog, so we don't need to understand." Therefore, these soil layers and rocks do not need to be represented in a visual picture, but can be represented as a blind picture. Later, when we enter the interior of the mausoleum, it will switch the way it is filmed, and we will have a visual view. Another benefit of using blind shots is to approach the target covertly. ”

Everyone understood Fu Ying's last sentence.

Blind shooting, in fact, is completely shooting in the dark. If there are other people in the environment, they will not be able to see where the "gopher" is located, and therefore they will not be able to see the "gopher". If the "gopher" is not shot blindly, but with visible light, it will be easy to expose the target. Even if you don't use visible light, you can use infrared light, which will be captured by the other party's sophisticated instruments. Therefore, the advantages of blind shooting are self-evident.

"How thick are these rock formations, and how long does it take for it to pass through?" Yang Hao asked again.

"From the data it came back, the rocks and soil layers were forty or fifty meters, to say the least, but it took four or five minutes at most to cross these obstacles. Fu Ying replied.

"What kind of tomb is this, how is it buried so deeply?" Heng Qi scratched his head.

"Now, it is neither a sealed earth tomb nor a mountain as a mausoleum, it is likely to use some kind of natural underground cave!" Fu Ying said.

"Underground caves, where does the door of such a tomb usually open, and how do we get in?" Heng Qi continued to scratch his head.

"It is impossible to enter any tomb directly through its tomb door, and the method of our upside-down fighters is to open a robbery hole. ”

"So, how do you dig a hole in the flat ground?" asked Huang Ranran, tilting his head.

"You only know how to dig pits, do you think it's digging coal?" Xie Ke snorted coldly.

"Isn't that the same? It's all about digging up the treasure buried in the ground, isn't it digging a hole in the mine?" asked Huang Ranran.

"Digging a hole and digging a hole in mining are two different things," Fu Ying replied seriously, "Mining and digging are quality-oriented, and the construction period is long, the scale is large, and it is carried out in public. Digging a thief hole is hidden, small and fast. Of course, concealment is not to be seen, small means that the scale is relatively small, and there is no quality to be paid attention to, as long as it can reach the tomb, and fast is a kind of technical requirement for digging a robbery hole. For example, in order not to be detected or preempted by peers, a thief is often required to be completed in a very short time, which may be a few hours or a night......"

"I see, because it's a shady thing, so sneaking around is like a mouse burrowing in the ground. Huang Ranran said with a smile.

"Huang Ranran, don't talk nonsense!" Heng Qi and Xie Ke scolded while looking at Fu Ying uneasily.

"What Brother Huang said is also the truth, and the line of fighting will not see the light of day. Fu Ying's face was very calm and calm. Indeed, I am in this business, so what is there to be afraid of what people say?

Huang Ran ran was actually unintentional. But people like him really can't find any decent words to use metaphors.

At this point, the monotonous gray honeycomb pattern on the screen finally disappeared, replaced by a hazy green. And through this green, you can already see some blurry real images. Yang Hao and the others carefully distinguished for a while, and could vaguely identify the shape of the rock and some open areas.

Fu Ying explained: "The 'gopher' has entered the underground cave, and it is now shooting with infrared light, and these images are the rocks in the underground cave that it has photographed. ”

Heng Qidao: "It's really not good to look at this kind of infrared light shooting, and my old Zhou really can't see what is famous." ”

Xie Ke nodded and said, "Well, it's really not good-looking." If only there was a light on it. ”

Huang Ranran naturally couldn't see anything, so he could only stare at the pictures on the screen without blinking with his mouse eyes open, imagining that he could understand those pictures.

After looking at it for a while, Yang Hao suddenly said: "It seems that this underground cave is very empty, and there is no trace of the ancient tomb." ”

"Brother Yang, please take a look. Fu Ying suddenly pointed to the screen and reminded Yang Haodao.

Yang Hao took a closer look and couldn't help but be stunned. It turned out that the picture was frozen for some reason, just like the photographer with the camera suddenly stopped, just stood in place and filmed, and the picture never changed.

In front of the picture, there is a vague wall. Under the infrared lens, you can't see what kind of wall it is.

Fu Ying's face became solemn: "This is the Xuanming Ghost Wall of the Underground Xuan Palace, and my 'Drill Gopher' can't pass through!"

"What is the Xuanming Ghost Wall?" Yang Hao asked.

Heng Qi and the others also pricked up their ears.

"The wall is said to have been made of materials from the underworld, and even the hardest diamond drill in the world cannot penetrate it. It seems that the owner of the tomb did take great pains to prevent the entry of the inverted fighters. Fu Ying muttered.

Indeed, not only are there so many prohibitions on the periphery, but this underground Xuan Palace is even rammed with the Xuan Ming Ghost Wall, which does take a lot of effort.

It's no wonder that the "gophers" who cut tofu through rocks and soil can't take a step further.

Fu Ying pressed a button on her body, recalled the "Drill Gopher", and then said to Yang Hao and the others: "Big brother, it seems that if you want to know the situation in the tomb, you can only go in and take a look in person." ”

Yang Hao nodded: "Not bad." ”

Heng Qi Zetou said: "How do you get in?"

"Of course it's a hole!" Huang ran and said at the runway.

"Huang Paoran, are you a mouse, you know how to make holes?" Xie Ke shouted and scolded.

"Monkey, you're wrong, this time I'm on Huang Ranran's side, he's right, we're going to enter the inside of the ancient tomb, and we really have to make a hole!" Heng Qi said with a smile.

"Maybe you don't have to be so troublesome—you come with me!" Fu Ying suddenly walked towards the side of the field.

The crowd didn't know what to do, so they hurriedly followed. I saw that Fu Ying walked about thirty or forty meters, suddenly stopped, and then waved his hand to signal everyone to be quiet and not make any sound.
