Entering the wide hallway, I began to look around carefully: the corridor was so deep that there was no end in sight, and there were many tightly sealed iron doors on both sides of the corridor, but strangely enough, the iron doors were bare, without handles, not even a keyhole, only a number marked with red paint.

Mu Xuanqing walked to the first iron door, which was marked with the number "0001", and he pushed the iron door hard, but the iron door did not move.

I know Mu Xuanqing's strength, even a centimeter-thick steel plate can be easily pierced with a dagger, but in the face of this iron gate, Mu Xuanqing seems to have become an ordinary person.

I saw Mu Xuanqing frowning, took out the dagger and slashed it hard, and a piercing "stab" sound sounded, but the iron door was not cut as I expected, only leaving a mark about a centimeter deep.

Xiao Ruyue and I both grew their mouths in surprise, obviously we both have a certain amount of confidence in Mu Xuanqing, but this time, Mu Xuanqing did not achieve the "invincible" we imagined.

Xiao Ruyue stepped forward quickly, and also took out the short sword from her waist and stabbed it a few times, but only left a few shallow marks.

"Why is this door so strong?" I limped to the door, and asked suspiciously while touching the knife marks on the door that had just been scratched by Mu Xuanqing.

Xiao Ruyue shook her head in confusion, stepped forward and groped carefully, frowning: "This door must be at least ten centimeters thick." ”

"Huh?" I looked at her in amazement, my eyes full of incredulity.

Mu Xuanqing stared at the door tightly, his original elegant and gentle temperament was gone, his body exuded a violent aura, his eyes were cold, and his pale face was like a Shura crawling out of hell at the moment.

Seeing his temperament change greatly, I couldn't help but be shocked: If this kid falls into some evil and goes crazy, I have to explain all ten here!

Xiao Ruyue was also startled when she saw Mu Xuanqing's appearance, and hurriedly asked, "Brother Xuanqing, what's wrong with you?"

Mu Xuanqing stared at the door fiercely, and said intently: "There are things in here that make me feel dangerous. ”

Listening to his words, I subconsciously stepped back, even this kid feels dangerous, I'd better stay away.

Mu Xuanqing thought for a while and said, "You two, retreat to the other side of the corridor." Xiao Ruyue looked at Mu Xuanqing worriedly, and just as she was about to say something, Mu Xuanqing raised her hand and touched her head and said, "Trust me." ”

Xiao Ruyue had no choice but to nod, and retreated to the other side of the corridor with my arms, looking at Mu Xuanqing's back, her eyes full of worry.

Looking at the appearance of the two of them, I couldn't help but tense in my heart, and looked at Mu Xuanqing nervously.

I saw Mu Xuanqing take a few steps back, pull out a pistol from his waist, and shoot four times at the iron door. With four loud bangs, the iron door was broken out of a hole, and a fragrance emanated from the hole, accompanied by the smell of gunpowder just now, and it smelled very strange.

Mu Xuanqing casually threw the pistol on the ground with all the bullets, pulled out the dagger with his backhand, and walked towards the iron gate, Xiao Ruyue and I looked at each other and hurriedly ran over.

Just as we were about to run to the iron gate, Mu Xuanqing suddenly shouted: "Hurry back!"

I was stunned by his sudden shout, and Xiao Ruyue immediately pulled me back.

As I stepped back, I looked up at the iron gate. I saw that the iron door in front of me began to tremble non-stop, and there was a loud sound of "dong dong" inside, as if something was about to break through the door!

Mu Xuanqing hurriedly retreated to me and Xiao Ruyue, staring at the iron gate tightly.

Xiao Ruyue also drew her short sword and gently blocked me behind her.

The iron gate trembled more and more, and at this time, Mu Xuanqing pulled out another pistol from behind his back, and hurriedly said to me: "Protect yourself!"

With that, he threw the pistol to me.

I hurriedly grabbed the pistol, and shouted as I held it in my hand, "Big brother, I won't use it!"

"Just pull the trigger!" Before Mu Xuanqing's words fell, he heard a loud "bang" from the iron gate, and the heavy iron gate fell to the ground, smashing up a large cloud of dust. In the dust, a figure stepped out of the iron gate!

I looked nervously at the figure, my hand holding the pistol trembling, and I roared in my heart: What kind of monster is this?

The figure slowly walked out of the smoke: it was a man in an old-fashioned Japanese military uniform, about 175 years old, looking at the three of us with vacant eyes, but it was incredible that he looked only in his 30s!

"Who are you?" I subconsciously yelled at the "person", and as soon as I came out, I secretly scolded myself for being stupid, and he couldn't understand Chinese, you roared a fart!

"Stop shouting, he's already dead. Mu Xuanqing said while staring at the man tightly.

"Huh?" I exclaimed, how is this possible, how can he still move if he is dead, and most importantly, there is not a trace of decay on his body, except for some shabby clothes!

"There is no sign of life on him!" Xiao Ruyue also said, her voice full of incredulity.

Just as we were talking, the "person" who came out of the iron door turned his head violently, and his bones made a tooth-sore "crackling" sound, and his empty eyes stared at us without the slightest feeling, staring at me so much that I almost cried out in fright. In the next second, the "man" rushed towards us!

Mu Xuanqing and Xiao Ruyue rushed out at the same time, and the two of them had a very tacit understanding, attacking the two ribs of the "person" respectively.

I saw that the "person" raised his hand and clenched his fist, and waved it at Xiao Ruyue, Xiao Ruyue was beaten upside down and flew out, and the short sword in his hand was also knocked down, and Mu Xuanqing had already reached the other side of the "person" at this time, and slammed the dagger into his heart!

The "man" let out a scream like an animal, and even knocked Mu Xuanqing back with his backhand, and grabbed Mu Xuanqing with his two hands like iron tongs!

"What are you doing in a daze! Shoot quickly!" Mu Xuanqing yelled at me hurriedly.

I quickly pointed the gun at the "man" and scrambled to pull the trigger.

"Bang" a gunshot, I was shocked by the recoil of the pistol and stumbled, and almost fell, and this shot was lucky to hit the leg of the "person", and the person knelt in front of Mu Xuanqing at once, but his arm still grabbed Mu Xuanqing.

At this time, Mu Xuanqing bounced up from the ground and yelled at me, "Throw the gun over!" I hurriedly raised the pistol and threw it at Mu Xuanqing hard.

Mu Xuanqing dodged the "man's" hands, caught the pistol I threw over, and shot the man twice in the head.

"Bang bang" twice, the head of the "man" was like a rotten watermelon, it was smashed by the beating, but there was no blood, but the white brain flowed to the ground, and after being shot in the head, the "man" crawled forward a few times with convulsions, and then remained motionless.

Looking at the brains all over the ground, I could no longer suppress the gastric juice churning in my stomach - "vomiting" I squatted on the ground and vomited.

Xiao Ruyue struggled to stand up, ran to me, and patted me on the back.

I vomited for a while, almost all my intestines came out, and the feeling of nausea slowly went away.

Xiao Ruyue dragged me up from the ground and said to Mu Xuanqing, "What is this?" Mu Xuanqing didn't speak, just walked up to the corpse of the "person" and rummaged for something.

Watching his movements, I almost threw up again.

After looking for a while, Mu Xuanqing seemed to have found something, waved at us, and motioned for us to come over.

I endured my nausea and walked up to Mu Xuanqing with Xiao Ruyue, I didn't look over, and tried not to look at the corpse.

"What do you think this is?" Mu Xuanqing took out something from the corpse, walked up to us, and spread his hand: it was a small glass bottle, about the size of a pistol bullet, and there was a small glass tube attached to the end of the glass, and a piece of the "human's" brain was connected to the end of the glass tube.

Xiao Ruyue hurriedly sat down with me, looked at the small glass bottle, and exclaimed, "Brother Xuan Qing, there is also a vermilion fish mark on it!"

Mu Xuanqing nodded, looked at it carefully, and after finding nothing, he shook off the brain and carefully put the glass bottle into his pocket.

I breathed rapidly, while looking at this corridor in despair, the endless iron doors were like iron coffins, neatly arranged on the wall, I felt countless eyes watching us in the iron door, I couldn't help but twitch in my heart: here, what is the place?
