The two of them walked inside for a while, and then An Wen found that there was a place similar to a culvert under the factory, and it was so dark that they couldn't see anything clearly, which was almost the same as a tunnel through the mountain on the highway.

There are a few simple light bulbs hung on the culvert, the yellow one, and it feels very kind after seeing it steadily, when I was a child, I used this kind of bulb at home, and later some people said that yellow light is not good for eyesight, and everyone slowly changed it to white light.

The workers had already slipped away, there was nothing under the culvert, and he looked at the crumbling light bulb above his head, his own shadow was cast on the ground, and in the darkness he suddenly felt like he was surrounded by horror, and he felt like he was making a horror movie.

"This is not a horror movie, I still have Luoyang, this should be a love art action movie. Tell yourself this in your heart, so as to give yourself courage.

"What are you doing here?" Luoyang said, looking at the moss-covered walls around him, "There's no fire here, I said you have a head pump." ”

"me, don't say a word, be careful, and come with me. ”

An Wen spoke, let go of Luoyang's hand, and walked towards the collapsed wall in front of him.

The structure of the underground culvert is very complicated, and the ground in front of it is full of various tools for work, such as electric drills, hammers, ink cartridges, plumb weights, etc., and he calmly took a tape measure from the ground, walked to the collapsed wall in front of him, and constantly measured various data.

"Luoyang, you can help me remember something, just use your mobile phone, remember that the order must not be messed up. An said as he looked at the wall in front of him.

Luoyang didn't know what An Wen wanted to do, but he still took out his mobile phone from his pocket and stood aside and waited for him quietly.

"The thickness of the brick wall structure is 24 cm, the thickness of the concrete wall structure is 20 cm, and the thickness of the non-load-bearing wall is 8 cm. An Wen said as he took the ruler and said next to the half-collapsed wall.

Luoyang was frightened on the side, this guy patted here for a while, touched there for a while, Luoyang looked at the exposed steel bars in the wall were crumbling with the steady action, she was really worried that this guy was careless, and the entire wall would collapse, which would cause the collapse of the entire factory.

"What are you stunned about, hurry up and remember. An Wen glanced at Luoyang and teased: "You are not qualified as a cost clerk, how can you do it if you don't remember anything?"

Luoyang pursed his mouth and said unconvinced: "I have long remembered, who is the same as you, grinding, stupid." ”

An Wen smiled and didn't speak, he put his hands behind his waist and began to circle around the walls of the entire underground culvert like an old cadre.

Luoyang saw An Wen's serious expression, and as he walked, he seemed to be thinking about what to calculate, so he didn't dare to interrupt this guy out of voice.

After a circle around the entire culvert, he stopped, looked back at the entire culvert, touched his chin and began to ponder carefully.

After a while, An Wen looked at Luoyang and said, "You come with me." ”

The two of them turned back again, and An Wen found a thin pipe from the place where the tools were stacked, and after thinking about it, An Wen found a water source again, and began to pour water into the thin hose.

There are no professional surveying and mapping tools here, An Wen can only use this local method to temporarily measure, he doesn't need specific data, he just wants to check whether his conjecture is correct.

After the long thin hose was filled with clean water, An Wen asked Luoyang to hold the end of the thin hose and stand here on the broken wall, let her press the thin hose against the wall, and then mark the water level inside the thin hose on the wall.

An Wen pinched the other end of the fine hose and came to the other place of the culvert, and every time An Wen went to a place, he would move the fine hose up and down until the news that the water level in Luoyang had returned to the original scale line, and An Wen would record the distance between the water level of the fine hose and the ground on his side at this time, and so on, he could infer the change in the terrain in the culvert through the comparison of distances.

After measuring, An Wen found that the culvert was not horizontal, but slightly tilted, which made him more firm in his conjecture.

"Come on, come on, do me another favor. An Wen said, "Let's measure the length and width of this place." ”

Luoyang rolled his eyes, who knows what this guy is doing, that is, she knows this guy better, otherwise when this kind of house is about to collapse, who will be idle here to measure things.

The two of them took the tape measure and measured the length and width of the culvert several times, and finally put the tape measure away and walked towards it with a frown.

"Hey, why are you in such a hurry?" Luoyang, who was left behind, asked, "You weren't slow just now, what's wrong now, the dog is chasing you?" ”

An Wen turned his head with a somewhat cold expression, glanced at Luoyang, and said in a low voice: "Don't talk nonsense, hurry up." ”

"Cut, and pretending to be mysterious. Luoyang whispered, "If you want to attract my attention, it's impossible, I won't be fooled." ”

An Wen suddenly stopped, turned around, stared at Luoyang and said gloomily: "You go slower, something will hold you and won't let you go, I don't care." ”

Under the dim light, looking at An Wen Tieqing's face, his tone was so cold, and the content of the conversation made Luoyang's heart tremble, why is this guy so annoying, pretending to be a ghost to scare himself.

"Bah, yes, I also stopped you from leaving. Luoyang said so, but his pace has quickened a lot.

An Wen didn't want to say anything more down here, so he didn't pay any more attention to Luoyang, and walked quickly towards the top.

When the two of them returned to the ground, they watched a group of people gather in the factory outside, turned around and secretly said to Luoyang: "Little Senior Sister, do you know what this large underground space is for?"

Luoyang tightened his sleeves, looked at An Wen and said, "Didn't you say that this was built by the Japanese in order to store supplies during the war?"

"Uh...... I guessed wrong before," An Wen rubbed his head and said, "You definitely don't believe it, you think I'm scaring you." ”

"What?" Luoyang immediately raised his vigilance, stared at An Wen and said, "You make your words clear." ”

An Wen's eyes glanced at the underground culvert, and whispered: "This place is a little unclean, it is estimated that many people have died here before, if my guess is correct, the corpses of many people in the war back then are probably buried under there." ”

Luoyang's face immediately turned a lot colder, she kicked An Wen's ass, and said, "Don't talk nonsense here." ”
