Gu Qinglan also became cautious, retrieved a small infrared induction measuring instrument from above, and opened the measuring instrument to take a look at it every time she made a certain distance forward.

"What is this?" Ding Ermiao had never seen that thing, and pointed to the measuring instrument in Gu Qinglan's hand and asked.

"This is a measure of the thickness of the soil layer in front of it, a new product, which is not very accurate, but it can reflect an approximation." Gu Qinglan explained: "When the infrared rays from this side shoot out, the light waves will be reflected back, and the automatic analysis will automatically analyze how thick the soil layer will be to penetrate." ”

Awesome, Ding Ermiao was convinced, and sure enough, the interlacing was like a mountain.

Combined with the measuring instrument and the compass, not far ahead, there is a hollow area, either an underground palace or an underground passage. At this time, the location is about fifty meters from the center of the square-

Gu Qinglan did not continue to expand forward, but excavated at the standing place, digging out a small space that could accommodate three or four people who could barely turn around and move freely.

"Why dig so big?" Ding Ermiao asked.

"The situation ahead is unknown, in case we open the passage and the other party suddenly attacks, we are in the straight passage, we can't dodge, very passive. This space can at least give us a place to hide. ”

Ding Ermiao gave a thumbs up: "Master!" ”

After digging this space, Gu Qinglan went up to guard and replaced Rosie to come down to check. Rosie entered the underground and also used the compass to investigate, and came to the same conclusion as Ding Ermiao, the corpse qi was powerful, and it was not far from the oblique top!

"According to such a powerful corpse qi, combined with the layout of the ground in the square, there should be a dungeon under the ground." Rosie was a little nervous and whispered:

"Brother Ding, have you ever considered what will happen to us after we suddenly open the passage? A team of zombies, or the big snake you encountered? Or maybe a team of armed plaza guards? ”

Ding Ermiao smiled bitterly and said, "I don't have a clairvoyant eye, how can I see the situation on the other side?" ”

"Therefore, we must be cautious now, dig little by little, and then it is best to know all the secrets of the underground without the other party's knowledge, and finally strike first and defeat the enemy with one move!" Rosie says:

"That soldier king, won't you not get the monitor? I mean, make a small hole first, put a pinhole camera over there, and monitor the movement over there! ”

"Okay, I'll go up and guard it, and replace it with Li Weinian and Gu Qinglan to arrange it."

Ding Ermiao grabbed the rope and climbed to the ground, and said what Rosie meant. Gu Qinglan thought about it for a long time and thought it was feasible, so she asked everyone to stop work and buy monitoring facilities first.

In this way, another day passed, Li Weinian and Luo Qian purchased computers and pinhole cameras, this kind of equipment is now everywhere, in order to meet all kinds of voyeurism of all kinds of people, they all understand, so it is not difficult to procure.

While Ding Ermiao and Gu Qinglan continued to operate underground.

Directly in front of the passage, Gu Qinglan made a hole that only allowed him to barely enter and exit, and drilled inside. Ding Ermiao was outside, and he could only see Gu Qinglan's legs.

Subsequently, Gu Qinglan's actions became more and more gentle, and she actually put down the sapper shovel and Luoyang shovel, and used a paper cutter!

Not only that, every time a layer of soil is hung up with a paper cutter, Gu Qinglan will pour glutinous rice soup on the wall, and after it cools, the second round of advancement is carried out.

"Too careful, huh?" Ding Ermiao muttered: "In this case, what year will it be able to get through?" ”

"Be careful to make the ship of ten thousand years. If we use too much force and get through that side all at once, if someone over there finds out, all our efforts in the past few days will be in vain. Gu Qinglan wiped the sweat from her forehead and said in a low voice:

"I am advancing layer by layer, and there is glutinous rice soup pouring, which can guarantee that if I finally dig up the thickness of a piece of paper, we will not be found over there."

With that, Gu Qinglan took out a lighter from her pocket, stretched her arms forward, and climbed into the hole again.

It didn't take much effort, after Gu Qinglan scraped off another layer of soil, she retreated, her face was full of irrepressible excitement and excitement, and she said in a low voice: "It's only half an inch, and you can get through!" You can install a pinhole camera later and see what's going on over there! ”

Ding Ermiao had a black line on his head and asked, "How do you know that it's only half an inch?" ”

Gu Qinglan raised the lighter in his hand and said, "This is a zippo lighter made in the United States, it told me." ”

I'll go, the Americans are so awesome, the lighters produced also have the function of measuring the thickness of the soil? Still so precise? Ding Ermiao was even more confused.

"The professional lighting tool of the tomb robbers is not a flashlight, nor a candle, but a zippo lighter." Seeing that Ding Ermiao didn't understand, Gu Qinglan had to explain and said:

"If you use a flashlight, then in such a small hole that only allows one person to enter and exit, there will be a feeling of isolation, because the brightness of the flashlight is very strong, which will cause a miserable white and distorted area in the visible range, and the invisible place will appear extremely dark, which will make people hallucinate because of psychological pressure."

Ding Ermiao scratched his head: "Then why don't you use candles?" ”

"Candles?" Gu Qinglan smiled and said:

"Candles are only suitable for staying at the lover's table to create a little romantic atmosphere for dinner. Or, in the church, be held in the hands of those good men and women, and sing with them the songs of prayer and blessing....... Tomb robbery, you don't need that thing. Because in a small working space, the smoke of candles will hinder our vision and sense of smell, understand? ”

"Speaking of which, your zippo lighter is still powerful, but what is so powerful about it, let's hear it." Ding Ermiao urged.

Gu Qinglan nodded and said, "First of all, the light of the zippo lighter is very soft and warm, and it will not divide the underground passage into a completely different black and white world like a flashlight; Secondly, its flame can monitor the oxygen content in the burrow at any time; Third, it can warn of landslides, and as soon as a small piece of earth falls, the flames will jump......"

"Then how did you use the lighter to detect that it was only half an inch thick?" Ding Ermiao asked.

These things are all knowledge, and I might use them one day. I don't need it, it's also good to brag with people when I talk about it.

Gu Qinglan shook her head and smiled: "It's very simple, I leaned the flame of the lighter up and found that there was an air flow over there." Based on the color and flickering of the flames, I judged that it was only half an inch thick. ”

Then, Gu Qinglan said again: "It's so dangerous, if you use a little bit of strength, it will go straight through there!" ”

Hearing Gu Qinglan say so surely, Ding Ermiao's heart was itching, and he put Gu Qinglan aside, and was about to go into the hole to take a look.

"Wait." Gu Qinglan grabbed him. Tip: How to quickly search for the book you're looking for
