Early the next morning, I said goodbye to Zhao Jing and went out to take the subway to go to school.

But the subway had not yet reached a stop near the school, so I got off the train early, changed to a bus, and came to a bus stop near the Okay Mingdu community.

After finding a hotel in this area, I checked into a room, locked the door, pressed the do not disturb button on the back of the door, lay down on the bed, and got out of my body.

Then, I took out my wallet from my trouser pocket, and then took out a silver coin the size of a one-dollar coin from my wallet, and applied some magic power to it.

A lanyard certificate glowing with silver light immediately floated in mid-air.

This is a special soul pass issued by the gatekeeper to the mage, so that when the mage wanders on the street after leaving his body in the human world, other mages will not come up to him indiscriminately and give him greetings from hell.

In the past, sometimes I was so anxious to get out of my body to do errands that I didn’t even have time to put it on. Thinking that it might take a long time to get out of my body this time, I thought it would be better to bring the ID.

After hanging the soul pass around the neck of my soul, I turned around and jumped out of the hotel room window.

We arrived at Building 3 of Okay Mingdu Community without incident, then followed the fire escape to the 16th floor of Unit 2, and passed through the security door of the house on the far right.

After entering the house, I saw the ghost of Liu Zhuang's mistress, "wearing" a hospital gown, lying on the sofa in the living room, with a rag doll on his head in a daze.

I walked up to her, lowered my head and looked at her with a smile.

When the girl saw me, she exclaimed "Ah!!", sat up straight, looked at the silver pass on my chest, and said: "Are you a mage? I haven't even passed the age of seven, you guys are here.

Have you taken anyone?"

I carefully observed her color and judged that she had been dead for four or five days. Then I shook my head and said, "I'm not from the same department as them."

The girl said: "Then...what department are you a mage?"

I said: "I am a staff member of the China Branch of the Criminal Investigation Bureau of the Yin-Yang Joint Office."

The girl said: "What department is that?"

I said: "It's equivalent to Interpol, of course it only deals with ghosts and ghosts."

The girl said: "Oh, I understand, why did you come to see me? I died of natural causes and was not killed by anyone."

I said, "But you killed an unborn child, right?"

The girl's expression immediately changed and she said, "Nonsense! The doctor said my condition was too serious and asked me to abort my child. Moreover, this is not something you just care about ghosts and monsters."

I said, "Well, actually, it's just a routine matter. I have a few questions to ask you. I hope you can cooperate."

The girl said: "Okay, you can ask. It happens that I haven't encountered many ghosts after my death, so it would be nice to have someone to chat with me."

I said, "How did you get in? Have you seen other ghosts? Looking at your dress, it means you should have died in the hospital."

The girl said: "Yes, after I died, I originally wanted to go back to my hometown to see my parents, but it was too far away, and the radio said that we ghosts in the first seven years of age were not allowed to take public transportation, so we had nowhere to go, so we came back here in front of the door.

I wandered around, and then Liu Zhuang came to pick up something, so I took the opportunity to come in."

I said: "Liu Zhuang also suffered from the same disease as you, did you know?"

The girl's expression dimmed and she said, "I know, before I died, he was still scolding me for not strictly checking the building materials during the decoration, which caused him to get leukemia."

I said, "Oh? How do you say this?"

The girl said: "It's a long story. After I got married with him, he gave me a large amount of money to buy this house and decorate it. Later, I got leukemia, but he still didn't abandon me and provided me with money."

to treat the disease, but then he himself discovered that he had the disease, so

He came here with a harmful gas tester and found that the formaldehyde in our bedroom seriously exceeded the standard, many times exceeding the safe value. So he thought that I used inferior decoration materials in order to save money, which caused both him and me to suffer.

He got sick and killed our children."

I said: "Wait a minute, did you just say that only the bedroom exceeded the standard?"

The girl said: "Yes."

I said: "Let's go to the bedroom and take a look."

The girl said: "Oh."

After entering the bedroom, I looked around and found nothing suspicious, so I said, "What are you talking about just now? Is the harmful gas tester still there?"

The girl said: "Under the coffee table in the living room."

I said, "Go get it."

The girl said: "But I can't lift it."

I patted my head and said, "Look at my brain. I'll go over and get it."

After that, I walked out by myself, found the harmful gas tester from under the coffee table in the living room, and took it back to the bedroom.

The girl looked at me with envy and said, "It's great to know magic. You can pick up things and enter and leave the house at will."

I smiled and said, "When you go to hell, if you didn't sign up for reincarnation or were forced to reincarnate for other reasons, you can still have these abilities, but then you won't be able to bring these skills back to the human world."

The girl said: "Well, I know, it was mentioned on the radio."

At this time, I carefully checked the harmful gas tester and found that it was inoperable. Although I knew where the switch was, I couldn't understand the numbers displayed on the LCD after pressing it.

So I said, "How do you use this thing?"

The girl said: "I don't know either."

I looked at the laptop on a small table next to the dressing table and said, "Is this computer connected to the Internet?"

The girl said: "Online."

So I walked to the computer, turned it on, opened the browser, and first read the "Insco Hazardous Gas Tester Manual" and compared it with the model number to understand the specific usage.

Then, I read the "Air Testing Standards" and wrote down the national safety standards for several major harmful gases.

After turning off the computer, I picked up the tester and pressed the on button.

I looked at the LCD display on the tester and it showed that the hcho (formaldehyde) value was 0.5, which means that the formaldehyde content in each cubic meter of air was 0.5 mg, which far exceeded the national regulation of 0.1 mg.

However, tvoc (total volatile organic compounds), c?h? (benzene) and other indicators are lower than the national safety values.

The girl stood behind me, looked around for a while, and said, "Mr. Master, do you see anything?"

I said: "Formaldehyde does exceed the standard. Let's go to other rooms and take a look."
Chapter completed!
