I hurriedly ran downstairs, and I saw Mu Xuanqing standing calmly in front of the door of the dormitory, looking harmless to people and animals, as if there was no one, and I couldn't see the tension of holding a gun at all.

"Oh, here you go. "I handed him the coat along with the volunteer tag.

Mu Xuanqing was stunned for a moment, took the tag and coat and said, "I can't wear such a compact clothes like yours?"

"Wear your egg," I gave him a fierce look, "I asked you to tie your waist, didn't you plan to walk through the door so blatantly?"

Mu Xuanqing smiled: "I can't see that you still have a bit of intelligence." As he spoke, he casually tied his coat around his waist, just blocking the position of his pistol at the back of the waist. I breathed a sigh of relief, and although I was covered, I was still nervous.

"Okay, don't think about it, there must be a road before the car reaches the mountain. Mu Xuanqing said to me while bringing the volunteer's tag, looking at his appearance, he didn't seem nervous at all.

I also put the tag around my neck, walked up to him, and flipped his tag over: "Be careful, I borrowed your tag from my roommate, don't be discovered." ”

Mu Xuanqing nodded, put away his originally elegant and gentle smile, his breath became a little cold, he looked up at the place in the bungalow area, and said lightly: "Let's go." With that, he changed his body and walked towards the school gate. I didn't speak, and followed him closely to the school gate.

The sky was overcast and the wind was blowing so hard that it looked like it was about to rain. Walking to the school gate, Mu Xuanqing stopped a taxi, and we went straight to the old site of 731.

In the car, Mu Xuanqing was sending messages on the phone, and I could feel that the atmosphere was very dull, because everything would have a result this time. After more than ten minutes, we arrived at the gate of the former site of Unit 731.

Mu Xuanqing and I got out of the car, but we didn't rush in. Because we still have to wait for a helper we invited - Xiao Ruyue.

About five minutes later, a black Mercedes-Benz stopped in front of us, and Xiao Ruyue stepped out of it.

Today's Xiao Ruyue is wearing a gray sportswear, a pair of sneakers under her feet, and her waist-length hair is combed into a high ponytail, dragging it behind her head, showing her youthful vitality. However, what I didn't expect was that Xiao Ruyue also carried a sign of a college student volunteer on her chest. I can't help but laugh secretly: it's worthy of being a childhood sweetheart, and even the moths are exactly the same.

Xiao Ruyue saw me and Mu Xuanqing standing at the door of the old site, so she hurriedly ran over and smiled sweetly: "Brother Xuanqing, Xiao Luohe, I've been waiting for a long time." Hearing her call me Xiao Luohe, the corners of my mouth couldn't help twitching.

Mu Xuanqing also pursed his lips, and then smiled: "It's not too late, we just arrived." ”

After listening to Mu Xuanqing's words, Xiao Ruyue's eyes bent into a good-looking crescent moon again, and said with a smile: "Come and let's take a photo." I couldn't help but whisper: "Why are we taking pictures? We are not here to visit, but we still want to take a group photo?" Xiao Ruyue didn't seem to hear it, took out the phone, stood between me and Mu Xuanqing, and smiled sweetly: "I want to take a picture, one, two, three!" Just when the shutter sounded, Xiao Ruyue's voice came from my ears: "You have to do a full set of plays." I turned to look at her, and her winks glanced at the policeman standing in the doorway. I couldn't help but sigh secretly: No wonder Mu Xuanqing would ask her to be a helper.

After taking pictures, the three of us lined up and walked towards the scenic area. Mu Xuanqing and Xiao Ruyue talked and laughed, and I didn't say a word to them because I was nervous.

When we got to the door, the police stopped us: "What are you doing?

Before I could speak, Xiao Ruyue stepped forward first and said sweetly: "Comrade police, hello, we are college students from XX University, and we are here to do volunteer practice activities. After that, she also showed her signature smile and raised the tag in her hand.

I thought to myself: Oh no! someone's tag is a fake!

But the police didn't look carefully at the sign in Xiao Ruyue's hand, just glanced at it, and then looked at me and Mu Xuanqing with signs around our necks, nodded and said, "It's a student, let's go in." ”

I was just about to breathe a sigh of relief when I saw the policeman in the door pull out a metal detector!

I kept roaring in my heart: Damn!

I didn't dare to turn my head to look at Mu Xuanqing, but I just glanced at him with my spare eyes: Mu Xuanqing's eyes narrowed slightly, and he immediately returned to his harmless appearance.

Xiao Ruyue and I both passed the test, and when I arrived at Mu Xuanqing, I felt that my heart was in my throat, as if it could pop out with a mouth.

I saw Mu Xuanqing walk over, lazily raised his hand, and when the metal detector approached him, he immediately made a piercing "Didi" sound!

I felt like my scalp was blowing up and my mind was blank. The policeman's eyes also suddenly became fierce, and at this time, Mu Xuanqing lifted the front of his clothes with a big grin, revealing the belt of his metal head, and said aggrievedly: "Isn't the belt okay?"

The policeman's eyes also softened, and he smiled dryly: "Okay, okay young man, let's put down your clothes and go in." With that, she patted him on the shoulder.

Mu Xuanqing smiled slightly and said "thank you". He walked up to us and led us to the headquarters building.

While walking with me, he said to Mu Xuanqing: "You scared me to death just now, I thought I was going to be discovered." ”

"No way. Mu Xuanqing said calmly.

Xiao Ruyue also said: "Don't worry, Xiao Luohe, Brother Xuan Qing's acting skills are first-class." After that, he covered his mouth and smiled.

When I thought of Mu Xuanqing's grievance just now, I couldn't help laughing.

"It's called skill. Mu Xuanqing said.

"Cut!" Xiao Ruyue and I had a special tacit understanding this time, and we rewarded him with a big white eye. At this time, we have come to the door of the headquarters building. We all closed our mouths in agreement and walked to the viewing area of the main building.

Today is Thursday, the weather is not very good, there is no one in the whole visiting area, the building seems empty, and a little cold, and the other visiting areas are not open because of protection and repair.

Walking through the corridor of the list of victims, Mu Xuanqing whispered to me, "Take me to see the things marked by the vermilion fish first." ”

I nodded, and led him and Xiao Ruyue to the exhibition hall inside.

Walking into the exhibition hall, I began to carefully look for the experimental equipment with the vermilion fish logo in the glass display case.

Walking to the center of the display case, I saw the experimental equipment, and quickly shouted, "Found it," but when I looked closely, my heart immediately fell to the bottom - the mark was gone!

Hearing my shout, Xiao Ruyue and Mu Xuanqing immediately ran over.

"Where?" asked Mu Xuanqing, staring at me tightly.

I pointed to the lab kit and said, "It was originally here, but somehow it disappeared." ”

"What?!" Xiao Ruyue and Mu Xuanqing shouted at the same time.

“…… How is this possible?" Xiao Ruyue muttered while leaning on the glass of the display case without believing evil.

Mu Xuanqing didn't speak, but her brows tightened.

The atmosphere was stiff for a while.

Suddenly, it dawned on me: I took a picture the last time I came!

"Hey, by the way, I took a photo last time, I don't know if it's useful. I hurriedly spoke.

Mu Xuanqing's eyes lit up, and he said eagerly: "Take it out and take a look!"

I nodded and opened my phone's photo album. Within a few clicks, I found the photograph - the lab equipment in the photo was exactly the same as the one in the display case, and the scarlet fish imprint happened to be on the base!

Looking at the photos, we breathed a sigh of relief at the same time. Mu Xuanqing picked up my phone and looked at it carefully, then said thoughtfully: "It seems that there is indeed a problem here,"

Xiao Ruyue and I both stared at Mu Xuanqing tightly, waiting for his next step.

"So, let's split up and look for it here, and in twenty minutes, we'll meet at the entrance of the main building. Mu Xuanqing thought for a while and spoke.
