When night fell, Lin Zihan changed into a smart tights, his sleeves were stuffed with silver needles, a crossbow launcher was specially tied to his left arm, and a dagger was stuffed in his boots.

"You are dressed ......" Lu Xin looked at Lin Zihan dressed in black, with an untimely windbreaker on the outside, a little out of place.

"What's wrong? Is there a problem? Lin Zihan looked at himself, straightened the collar of his windbreaker, confirmed that all the weapons he had prepared were ready, and finally crossed the windbreaker with both hands, and stood up straight, as if waiting for review.

"What are you doing with a trench coat in a tights?" Lu Xin was very puzzled by Lin Zihan's strange dress, as if he was wearing bells and whistles inside, and there was a sack on the outside.

"Tights for ease of movement, jackets to hide identity." Lin Zihan explained that he didn't think there was anything wrong with it.

"I'm starting to wonder now about your professionalism as a killer." Lu Xin shook his head, tightened his shoelaces, and tucked his twin blades into the scabbard at his waist.

Looking at Lin Zihan's strange outfit, Yan Bing also began to wonder, this younger brother of his own, wearing a night suit is so strange, is it really the killer night charm of the famous Long City?

"I'll get out of the guards, you have three minutes, disappear from this floor, remember not to take the elevator, the exit of the elevator is the guard." Yan Bing advised, stepped forward to straighten Lin Zihan's clothes, and pulled a windbreaker as smooth as a steel plate.

"Remember, don't use exoskeletons unless necessary, and now the patrol team of the Nandu Security Bureau is equipped with a detector that can detect any form of teleencephalon signal fluctuations." Yan Bing is still not at ease, although there was an instrument to detect the brain band of the driver before, but now the instrument is more accurate, and it can clearly detect the strength level of the exoskeleton.

"Got it, Sister Bing." Lin Zihan looked at the silver needle on his wrist, without the exoskeleton, Lin Zihan's hand-to-hand combat ability is also stronger than that of ordinary enhancers, after all, Lin Zihan once ran rampant in Longcheng, relying on his own outstanding physical fitness, not to mention that now he has the baptism of dragon blood.

"You two, go look over there on the rooftop, I just heard a voice upstairs." Yan Bing walked out of the room, glanced at the two guards guarding the door, and waved his hand.

Seeing that the two guards did not move, Yan Bing continued: "You go, it's enough for me to watch here." A fierce light flashed between Yan Bing's eyebrows, even if Yan Bing no longer had a very high status in the secret service as before, these shrimp soldiers and crab generals didn't dare to say anything.

"Yes!" The two guards walked away in amusement, after all, no one wanted to mess with this iceberg, she started a fire, it was an active volcano.

"Let's go." Yan Bing gently pushed open the door and beckoned to Lin Zihan and Lu Xin, with Lu Xin here, Yan Bing was not so worried about Lin Zihan's safety.

The two of them walked out of the corridor against the wall, turned around and ran quickly into the fire escape, this is the seventeenth floor, the top floor of this hotel, but for the two of them, from the roof to the ground, it only takes less than a minute.

Holding the handle with both hands, Lin Zihan swung directly from the handrail on the seventeenth floor to the first floor like a swing, and then landed lightly with his feet and slowly pushed open the door on the first floor.

"Why don't you go underground?" Lu Xin pointed to the back of the hotel, an inconspicuous iron gate, marked with four big characters, underground entrance.

It was the entrance to the dungeon built by humans when the beast tide broke out, relying on the subway line, to build one dungeon after another, in addition to not seeing the sun and the moon, there was no wind and rain, and there was no difference from the ground, and humans also built a complete air cycle and water cycle.

However, later the beasts that could travel underground were infected with the virus and became fierce beasts, and the beginning of the counterattack with humans, the dungeon was gradually neglected, and humans regained the land on the ground and established the current city fortress.

Gradually, the dungeon was forgotten by humans, but in some cities where the defense line was not very stable and the beast tide broke out frequently, the dungeon was still operating.

"Isn't this like a mouse?" Lin Zihan looked at the entrance, it was about to be sealed by cobwebs, obviously no one had opened it for too long.

"How do I remember that when you were in the training camp, you were beaten up by Instructor Ling ......" Lu Xin looked at Lin Zihan's reluctance and began to quip.

"Let's go." Lin Zihan hurriedly echoed, just now Lin Zihan saw that in the hall, there were twenty or thirty people from the Security Bureau, one by one, like searchlights, scanning the entire hall.

"Click, click~" Lu Xin directly split the iron chain locked on the door of the underground entrance with a knife, and the lock that was already full of rust was already rusted. As the lock falls to the ground, some rust is emitted from the cylinder.

Gently closed the heavy iron door again, even though Lin Zihan had tried to be as light as possible, the weight of the door still made a dull crashing sound.

"What sound?" The security guards who happened to be patrolling suddenly looked at the iron door with alarm.

"What can it be likely, it's a mouse." The other guard looked at the dusty iron gate, and did not suspect it, after all, at the end of the fire escape that no one had ever set foot on, the iron door had been abandoned for an unknown number of years, and did not notice the iron chain in the corner.

Walking through the stairs all the way down, Lin Zihan saw an elevator door, now Lin Zihan doesn't know where he is, the passages here extend in all directions, criss-crossed, and have completely stunned Lin Zihan, who has a general sense of direction.

"Will this elevator still work?" Lin Zihan looked at the elevator door, the ash on it was already a finger thick, and Lin Zihan even doubted whether the elevator here could still guarantee safety.

"Just try it." Lu Xin cautiously leaned forward and pressed the button on the door, accompanied by the sound of a not-so-smooth metal chain, a clattering sound of metal, and the sound of a smooth zipline.

The sound of the zipline kept ringing, from far to near, from near to far, Lin Zihan couldn't tell where the sound was, only that the sound was still ringing, Lin Zihan didn't know where the elevator was going to come from, but Lin Zihan confirmed that the elevator inside was working.

After waiting anxiously for more than a minute, the sound in the elevator door finally stopped ringing, and the dusty elevator door slowly opened, and a fresh air came, not as revealing the damp smell as in this tunnel.

Looking at the clean appearance of the elevator and spotless, Lin Zihan was a little suspicious, is this elevator really connected to the outside?

"Do you feel that the air in this elevator is very fresh, not at all like this tunnel, which has been dusty for so long, and there is a smell of dampness everywhere." Lin Zihan looked at the stone walls on both sides of the elevator door, which were already covered with moss, and the light in the elevator came out, and Lin Zihan could see clearly that his feet were also a piece of dust.

"You'll find out if you go in." Lu Xin was obviously not afraid, she had once entered an abandoned dungeon when she was on a mission outside, and there was nothing terrible except for some abandoned products of various human societies.

"Let's go, then." Lin Zihan stepped into the elevator first, there was only one button in the entire elevator, and a snake-shaped pattern was printed on the button, and the golden snake scales seemed to exude a rich atmosphere.

Lu Xin also walked into the elevator, and as the elevator door slowly closed, the elevator ran on its own.

Lin Zihan clearly felt that the elevator was not going straight up and down, but moving horizontally, as if it was a moving train.

In the narrow space of the elevator, Lin Zihan felt that the passage of time had slowed down, and his fingers gently tapped on the side of his thigh, tapping to calculate the time.

"Three hundred and one, three hundred and two......" Lin Zihan continued to read silently in his heart, looking at Lu Xin in front of him, the light powder makeup made Lu Xin look not as terrifying as she showed, and the lilac dagger scabbard on his waist revealed a little.

"Ding~" The elevator door opened slowly, and outside the elevator door, there was no dark passage as Lin Zihan thought, a piece of dust, exuding the smell of dust and moisture, or a passage covered with moss, and the sound of water dripping across his ears.

What appeared in front of Lin Zihan was a bright passage, and the lights on both sides emitted light, allowing the whole passage to be seen clearly.

"It doesn't seem to have been abandoned, but people have always lived here, and the air here is as fresh as the outside." Lu Xin looked at the ground, although he didn't say that it was spotless, but there was not so much dust.

"I've heard that some underground organizations use abandoned dungeons as bases, so we won't break into ...... by mistake" Lin Zihan looked at the end of the passage, his ears tried his best to catch the sound that came, in that direction, Lin Zihan could hear it, there was a subtle sound.

"Perhaps." Lu Xin didn't hear the sound in the distance, but began to walk along the passage, slowly walking forward, his steps were very light, his right hand fell on the hilt of his knife, and his eyes looked around.

"Someone here must have just smoked some kind of inferior cigarette and mixed with some magazines, like some kind of chemical." Lu Xin looked at the cigarette butt in the corner, his nose sniffed in the air, and Lin Zihan clearly smelled some kind of pungent smoke and chemical smell in this air.

"It's a hallucinogen." Lin Zihan also smelled the smell when he got closer, as Lin Zihan, who had smoked cigarettes with special chemical agents, Lin Zihan still had some understanding of the substances added to cigarettes.

This smell is one of the cheapest and most common hallucinogens, but this hallucinogen has obvious side effects and the dosage is not easy to control, so few people choose it.

"It seems that this underground is really a kingdom of sin." Lin Zihan knew that most of the people who smoked these cigarettes were people who had suffered from physical torture, and the people who could get these additives were not simple citizens, they were all people who had close contacts with underground organizations, after all, these contraband, even if they were in the underground black market, the gold card could not be bought.

"Is this kind of thing only made by some underground organizations?" Lu Xin looked at Lin Zihan's expression, she seemed to understand that these medicines were contraband, to be precise, some medicines that were not in circulation.

Lin Zihan didn't respond, just nodded.
