The two of us exited the utility room, returned to the room to grab the flashlight, and continued to look for clues. I don't understand where this key is, every room is a key card used, and there is no need for a key at all, obviously this key is the key.

"Where do you think it will be?" I handed the key to the stone to hear what he had to say.

Stone took the key, looked at it, and said to me, "According to my analysis, this key must have been deliberately left in the utility room, and he was probably hiding something."

I gave him a blank look: "Can you say something I don't know!"

"Let me think about it! So, first of all, let's make a hypothesis, you see, this key is so small that it can be thrown into the toilet, and there is no need to throw it in the utility room. So I guess the situation must have been urgent, and he didn't have time to throw the key into the toilet, or even dare to take it with him, so he threw it into the utility room. "The stone walked around me, expressing his opinion.

I thought about it, and there was some truth in what he said, so the man must be trying to hide something.

"And where do you say the key is?" I asked, looking at the stone.

"It's not a guest room, it's a computer room?" Stone frowned and analyzed.

"Machine room, what machine room?"

"Power room, let's go, go up to the rooftop and have a look." The stone seemed to suddenly understand, and he was not as scared as he was at the beginning, and after he finished speaking, he ran in the direction of the elevator.

There are 20 floors in this hotel, and we took the elevator to the rooftop. It was pitch black and I couldn't see anything, so I turned on my flashlight and searched the rooftop. It is a large area, and there is only one room in the middle of the roof, which should be the power supply room.

The two of us walked to the door of the power supply room and tried the key against the lock hole, but it couldn't be opened, it didn't seem to be here. But there was no other door except the power room, and I really didn't know where the key was.

That yin spirit just now seems to have left us, I think it should be afraid of the yang energy on the stone's body, this guy doesn't know if it's too frightened or what, the yang energy on his body is getting heavier and heavier, and it has far exceeded the aura carried by me. The reincarnation of the gods is really different, even if they devour the spirit of the dragon, they can still exude such a pure yang energy, presumably even my master couldn't do it back then. It's just a pity that the stone doesn't know the secret art of yin and yang, otherwise he will definitely be able to become a new generation of heavenly masters after Zhang Daoling in the future!

"Look, there's a lock here." Stone said to me with a flashlight shining on a square tin box.

The iron tank was stained with oil and a thick layer of dust, and it looked like a large tank. It's just that this tank is different from a normal fuel tank, it has a lid on it, which can be opened.

"What is this for?" I leaned closer, ready to pick the lock, but I was afraid to see something I didn't want to see, so I stopped what I was doing, looked at the stone and asked.

At this point, I've already guessed a clue, the ghost led us to the key, there must be some purpose in it, there must be something wrong with this tank. I once saw a homicide case on the Internet, after the murderer killed, he hid the body in some large boxes, which are usually not easily opened, and even if they are found in the future, the body has already decomposed, and there is no way to verify who killed it.

I wonder if there's a corpse hidden in this tank!

"It's supposed to be an automatic power supply system, and when there's a power outage, the engine will automatically start to supply the entire hotel with electricity, and turn it on." Stone said to me with a flashlight.

"It's better for you to come!" The stone wanted to pick the lock, but hesitated to say to me.

I handed him the flashlight, and without hesitation, I put the key into the keyhole, turned it slightly, and sure enough, it opened.

I forcefully lifted the lid of the tank, and a foul smell came from the tank. Looking inside with a flashlight, the fuel tank was yellowed engine oil, and a figure could be faintly seen underneath. I hurriedly took a step back, pointed to the yellowed oil and the stone, and said, "Come and see what's in there."

"Holy! Dead man......" After looking at the stone, he took a few quick steps back and began to retch.

It's really hard for him to think about it, when he was with me, he rarely saw dead people, and it was normal to have this kind of reaction.

I beckoned him to leave and called the police. A few minutes later, the police arrived overnight and took a note of it.

It was only now that I realized that the body in the tank was a staff member of the hotel, a woman, in her early twenties. A few days ago, the girl disappeared suddenly, and the hotel manager called the police, but she couldn't find her whereabouts, and she didn't expect to be killed!

The rest has nothing to do with me, and I believe the murderer will be brought to justice. Seeing that it was almost dawn, after making the transcript, we each went back to our rooms to rest, before entering the room, I felt that there was yin in the corridor, so I looked back, and I seemed to see a void figure at the end of the corridor waving to me.

I was finally able to fall asleep peacefully, and after lying down, it didn't take long for me to fall asleep. No dream, I was woken up by Ji Xueyan in the morning, and after looking at the time, it was already eight o'clock. I opened the door and welcomed her in, and I was a little embarrassed to see her, I saw her body last night, and I don't know if she remembers.

I asked her tentatively, "How was it last night?"

"Well, it's okay, but I drank too much and couldn't remember anything! By the way, I didn't talk nonsense last night, did I? ”

I hurriedly waved my hand: "No, no."

I didn't talk nonsense, but I took off my clothes in front of me. Of course, I can't let her know about this, or she will definitely misunderstand me.

"I'll go and tell them to get up, you pack up, it's time for us to go." With that, she walked out of the room.

I breathed a sigh of relief, washed up, and began to pack up. This girl seems to be more anxious than me, has she lived in a big city for a long time, and everyone will miss the countryside. Indeed, I miss it a lot, I grew up in the countryside, and there are memories of my childhood. It's a pity that the place I went to this time is not my hometown, but it doesn't matter, I will be able to see Uncle Fang soon, it's been ten years, and I don't know how he is doing.

Half an hour later, everyone packed their bags, we checked out of our room and took a taxi to the bus station. Before leaving, I took a look at the hotel, and I was shocked to understand what was going on when I first came to the hotel. It turns out that this hotel, like Huaxia University, is built on fierce land!
