"Is the firefly behind the scroll?"

Coming to the square hall, the moonlight slightly illuminated the ground through the door of the mental hospital, and Jia Xin's eyes only saw the paintings hanging on the pillars in the service desk in the center of the hall.

However, in front of the hall, wisps of dark gray smoke rose from the moonlit ground.

"Worm Firefly, you and Zhang Chen go to the entrance of the corridor that is suspected of leading to the underground first, and I'll trigger the switch."

Jia Xin naturally noticed the changes at the gate, and the pale arms made Jia Xin feel the threat of death. Jia Xin stepped into the service desk, and with both hands tore the painting from the wall.

"Combination lock?" A small switch at the back of the painting is held tightly by a four-digit combination lock.

After all, the ability of the insect firefly is limited, and it only uses the insect swarm to search for some specified things, and the IQ of the insect swarm is not high, and it can respond correctly to corpses, blood and other objects. But for objects such as 'switches', the insect swarm naturally doesn't know what it is, and can only look for it according to the description of the insect firefly.

"Four digits, four digits!" Jia Xin had already caught a glimpse of the mist slowly approaching him, leaving him less than ten seconds to think.

"Time?" Jia Xin mobilized '0930', but there was no reaction at all with a click.

"How can it be so difficult, the simple information of the elevator can go directly to the eighteenth basement floor. And this hidden information is not only dangerous, but also has a combination lock that does not know where the information is. Jia Xin's head spun at a high frequency and began to search for a large amount of information in the temple of thought.

"The contents of the envelope, the lines of the map are kind of like ...... Morse code, as long as you put a dot between the lines is Morse code. Reorganize, sort! Jia Xin felt that his brain was about to explode, and he only relied on his own brain without calculus to directly decipher the code. The difficulty is unimaginable.

The most important thing is that there are still five seconds of time left for yourself, and even the computer needs a time to decipher, rearrange, search the number, and reassemble.

"9......" When Jia Xin calculated the first number, the time was still close to three seconds. The bright red fingernails in the mist were less than a point and a half meters away from him.

“7。 It's too late! Let's get out of here for a while......"

Just when Jia Xin wanted to give up, Zhang Chen, who was not far from him, reported four numbers, '9718. ’

Jia Xin's eyes lit up, and he immediately dialed the password to the designated position.

"Click!" The moment the lock was opened, Jia Xin pulled down a switch similar to a wrench. On the ground where Worm Firefly and Zhang Chen were standing, the floor a few meters later began to move slowly on its own.

"Jia Xin, hurry up!"

Red fingertips swept across Jia Xin's cheeks, and the latter jumped out of the service desk to stand with Zhang Chen and the others.

Jia Xin, who had a bloody mark on his cheek, swallowed a green pill into his mouth without slackening, and the wound healed immediately, and at the same time, the True Yuan riot in his body caused by the wound also subsided.

As the underground stone slab slowly moved, it opened. A bright red color was emitted from it, and the people who were rushing to enter the hidden corridor gradually slowed down their movements, because in the eyes of everyone, within the range of the red light, the fog could not penetrate half a minute at all.

"Is this the so-called 'little red dot'? I didn't expect the light to be useful for suppressing the fog. ”

The floor was fully open, and in the eyes of the trio, a small round sphere bulb appeared on the side of the stairway. It was the red glow emanating from inside that prevented the mist from penetrating for half a minute.

"Let's go down quickly, lest anything unexpected happen."

The structure of the underground passage is similar to that of a staircase on a normal floor. The fold-back staircase extends into the ground in the middle of nowhere. And every 10 meters there is a small red dot, knowing that the red light area is safe. Whenever the three of them are in the 'little red dot' area, it will make everyone's mood relax.

"Zhang Chen, how did you deduce the Morse code just now?" When he went about 100 meters underground, Jia Xin motioned for everyone to take a break in the 'little red dot' area and asked Zhang Chen.

"Morse code? It's just that the clown sues me four numbers, let me sue sù you. Zhang Chen only now realizes how rare these four numbers are.

"Joker?" Jia Xin smiled slightly.

"If I'm not mistaken, the so-called eighteen underground floors should be an incomparably huge labyrinth. From the most superficial information. That is, the elevator enters the eighteenth floor, which should reach the outermost layer of the maze, or the most dangerous area. And if we go down from here, it is very likely that we will reach the inner layer of the labyrinth, even if it is to the edge. It should also belong to a simple and safe edge area. ”

"Now we have two useful information, the woman hidden in the fog is easily attracted to the light, and the area covered by the small red dot light is safe, I believe there is other information besides."

"Is that woman in the mist 'she' the one who is being held here?" Firefly asked.

"I don't know." Jia Xin shook his head, "Anyway, let's go into the eighteenth floor of the underground first, what we experienced before were some small fights, and we will face the real horror at this time later." Keep going down......"

Jia Xin quickened the pace of the downward path, the insect firefly naturally followed, and Zhang Chen walked alone at the back, but his brain was constantly thinking about one thing.

"Oh? You feel it, Zhang Chen, right? The clown's voice echoed in Zhang Chen's mind.

When he passed by the misty woman in a dead end before, Zhang Chen's eyes and the woman's pupils looked at each other, although the time was only less than half a second, Zhang Chen felt as if he had spent a whole few days. The information read from those bloodshot eyeballs made Zhang Chen not really react now.

"The woman...... If it is really released, many, many people will die. It's not just Dongying, the world will be in turmoil. Zhang Chen saw something terrifying that he had never seen before.

"What are you going to do?" The Joker asked.

"This place is nothing more than the best place to absorb the mouth, and it is also the best opportunity, and I plan to take back the strength of my body here first. Then, try to get out of here. ”

"Do you think you can get out of here? It seems to me that from the moment you entered the hospital, or rather from the time you got the letter, you were already targeted, and the so-called hospital was really just a front. Unless you release her, if I want. Otherwise, you'll never be able to really get out......"

Zhang Chen from the outside world nodded, stopped talking, and followed Jia Xin towards the eighteenth floor.

"It's here!"

The folding staircase went down about three hundred and sixty meters, and finally a rusty iron door appeared below, the air here was extremely humid, and Jia Xin's right hand held the heavy iron door open on the damp doorknob.

"Huh?"

The scene beyond the iron door was not a long, dark passage as the trio had imagined, but a larger room. A small red dot appears at the top of the center of the room, illuminating the entire room with red light.

"Looks like we've really taken a lot of shortcuts."

In the square room, there is an iron door on each of the four sides, except for the iron door that you enter here from the staircase, you still have three choices.

"If I'm right......"

Jia Xin turned around and closed the iron door that his group had come down from the staircase, and then opened it again, and the previous staircase disappeared and became a bottomless passage.

"The four gates of the southeast, the northwest, give us four choices. This room was supposed to be a buffer zone, a central buffer zone for the entire eighteen basement floors. ”

"Shouldn't the center be the place where 'she' keeps her zài?" Firefly asked.

"No one tells you, 'she' must be in the center. If the elevator is located on the west side, it is most likely that 'she' will be held on the opposite east side. Of course, this is just my guess, and now our purpose is not to rush to release her, but to let Zhang Chen absorb your mouth. ”

"I'm 60% sure that this central area room will pass through here, Zhang Chen, what do you think? Speaking of the clown, does he have any plans? Jia Xin turned his head to look at Zhang Chen.

"Hmph, be a clever boy. Even if 100% of the people pass through here, ambushing them here is not the best option. None of the 'troublesome stuff' can kill it directly, let alone the three of us. Zhang Chen, you sue it, let him go to the west, and break off with your main soul in the western area. ”

"West? Isn't it possible to meet the mouth in advance? ”

"Yes, we have to meet him in advance so that we have a chance to understand, right? Sue him. ”

Zhang Chen was silent for a while and a half, then looked up at Jia Xin and said, "The clown said let's move towards the west." ”

"West? It seems that we have thought of a piece, but in this case, once we stumble, there is no possibility of turning back. In that case, let's go west. ”

"Crunch!" The iron door facing west opens.

In front of everyone is a bottomless dark passage, the concrete walls on both sides of the road occasionally overflow with small water droplets due to dampness, and there are faint red lights in the depths, and there are many branches on both sides of the passage.

"Go straight, and you will put an insect into the branch path every time you reach a branch firefly. Let's make a break with Kou Yan here, no matter how strong he is, he must die this time. ”

Jia Xin walked in the forefront, the fingers of his palms constantly changing, constantly calculating a very large number of jù.

When you reach an intersection, the reassuring red lights of the road ahead suddenly disappear, and the same red lights light up in the distance of the corridor on the left.

This change made Jia Xin a little unexpected.

"Go right...... Hurry up! Jia Xin's eyes moved, and he led everyone into the bottomless dark passage on the right side...... (To be continued......)
