"careful!"
The young policeman smiled, pointed his finger in the air, and a makeshift bridge was erected. Under the dim light, Qiu Shui could see a huge pit under the bridge!
Like a meteorite crashing down from the sky, the massive shockwave destroyed everything, cracking the ground around the building and creating a huge crater near it.
It was only then that it was discovered that part of the building had sunk into the pit, with about two floors visible underground, estimated to be about seven meters deep.
Stepping onto the bridge, I followed the young policeman in front of me through the broken third-floor window, and a very stuffy smell hit me.
"I'll be waiting for you outside. If you need anything, click this button and I'll rush over to help you."
The young police officer handed each of them a button and then walked out of the building.
"Sister Yuyu, can you smell something?"
They felt as if all the air in their chests was being sucked out; the gas in the building wasn't air at all, and they were going to suffocate!
Xu Yu paused for a moment, then took out a small bottle from her pocket and poured out two candies.
"It will be better if you take this in."
She put two pills in her mouth and gave her two more. Without analyzing the ingredients, Qiu Shui quickly swallowed the pills and indeed felt much better.
"Are you done?"
Xu Yu turned on the purple light flashlight and turned around to ask with concern.
"Let's begin."
Walking through the quiet building, which was pitch black inside, while the wind howled outside, there was not a breath of wind inside, as if the air had been frozen.
Is there something wrong with the computer?
"No."
"The generator is broken; it must have been electrocuted."
The two walked and inspected the building, using the analysis system to examine all the remaining equipment and machinery.
After observing for a while, the fear in her heart was slightly masked. Walking on the elevator she used to be in, Qiu Shui was very puzzled.
"No lightning rods were installed? How could there have been a mass electrocution if there were lightning rods?"
Passing by a charred human body, she asked in fear.
"I checked the information before. This building is called Friendship Building. It has been equipped with lightning rods since it was built, and there has never been an accident in decades, so..."
Xu Yu paused for a moment, a complicated expression on her face.
"Police suspect that someone tampered with the lightning rod, deliberately directing electricity into the building instead of into the ground, so we need to find out the real cause of the electrocution."
"Could it be that the equipment is old and the lightning rod is no longer working?" Qiu Shui asked again.
Xu Yu shook his head. "Banbu is a rainy city, and the lightning rods here are installed with much more precision than in other cities. This building is no exception, so it couldn't have been caused by natural causes."
Qiu Shui looked out the window with some skepticism and saw the cables and safety facilities connecting the floors.
"Have you studied the structure of lightning rods?" Xu Yu asked.
"No."
Qiu Shui looked around and saw the moon obscured by dark clouds in the sky. She suddenly realized that they should be on the middle floor of the building now.
The thought of the dense black figures around her and this eerie building made her tremble.
This place is far from the police...
She glanced at Xu Yu; she seemed unaware of their predicament and was still thinking about lightning rods.
"Autumn Water!"
Xu Yu's voice suddenly rang out, startling Qiu Shui. "What's wrong?"
"A lightning rod is a device that protects buildings and electrical equipment from direct lightning strikes. Its function is to divert lightning to itself and safely discharge it into the ground. It consists of three parts: a lightning arrester, a grounding down conductor, and a grounding electrode. A lightning rod provides a certain level of protection and has a defined protection range. Let's take a look at how effective its grounding is!"
As she spoke, her gaze went straight downstairs, the rays passing through all the buildings and landing on the ground below.
"No problem..."
Xu Yu murmured, "How could there be no problem? Most lightning accidents are inextricably linked to the grounding electrode..."
"Structure is being analyzed..."
The electronic butler is running, transmitting the data it receives to Qiu Shui's ears via earphones.
"The lightning rod on the tested object had two layers of anti-rust paint, indicating it was a cheap, unbranded lightning rod. It had broken off from the building structure at the connection point."
disconnect?
"Sister Yuyu! The test results show that the lightning rod has been disconnected from the ground!"
Qiu Shui quickly told the thoughtful Xu Yu the result.
"What?"
Xu Yu was taken aback. "Really? I didn't find anything. Wait..."
She examined it carefully again, but still couldn't find the problem. However, she discovered a small, unexpected issue.
"Logically, the death zone shouldn't be this large after a lightning rod malfunctions, and the electrical intensity shouldn't be this strong. Usually, there would be deaths and injuries. Why did all the employees in this building die? There are specific devices between each floor, so how could there be such a large area of ​​casualties?"
In other words, even without connecting a lightning rod, if electricity were to enter the company directly, it would not cause such damage.
Why is that?
