It turned out that the symbol on the blackboard, this was really a code puzzle, Mo Chen's brain was running rapidly, his fingers left the knob, and he inadvertently turned the knob around, and the original symbol suddenly became a number again.

Mo Chen twisted the knob again, and the number changed back and forth from 0~9 and a specific symbol.

"I see, each knob corresponds to a symbol here." As Mo Chen spoke, he twisted the other three buttons a few times, and the symbol that appeared in the small display corresponding to each button was a symbol on the blackboard on the left.

The attendant's eyes lit up, and he unconsciously shouted, "Eh, I understand, you mean, just adjust the number of the knob correctly!" ”

"Yes." Mo Chen said.

The follower approached the electric box, "That's simple, just try it, it's only four buttons anyway." ”

"Idiot!" Fang Xiaoxue muttered and rolled her eyes.

With Ben snorted coldly in his nose, "Idiots are not idiots, it's good to be able to get the answer right, it's better than standing and counting things with white mouths." ”

Mo Chen was in no mood to listen to the two arguing, he probably had an answer in his heart, he substituted numbers in his heart, and compared the graphics of the symbols. Mo Chen noticed that the number obtained by extending upwards from the two symbols was larger than the number derived from extending downwards.

Since the result of the launch is a number, it is nothing more than the relationship between addition, subtraction, multiplication and division.

Soon Mo Chen introduced the numbers corresponding to each symbol, and Mo Chen said, "The symbols from left to right correspond to the numbers 5, 4, 3, and 2 respectively. ”

Mo Chen revealed the mystery of the code, and the attendant excitedly followed the answer given by Mo Chen and moved the knob.

Just as the attendant was about to adjust the last knob to the number 2, Dai Min suddenly grabbed the attendant's wrist and stopped his movements.

"Don't!" Dai Min said hurriedly, "I'm not sure what this answer will cause...... So...... Don't ......"

Dai Min's uneasy gaze glanced at the iron doors closed on both sides of the corridor, and her worries were self-evident.

Hearing Dai Min say this, the attendant touched the hand of the knob, and Mu Mu froze.

"Brother......" The attendant looked at Mo Chen for help, and he was also worried about what Dai Min said, once these knobs controlled the iron gate where the walking corpses were held, then they really did the stupidest thing in history.

Mo Chen didn't speak, Dai Min's worries were right, after all, no one could prove whether these knobs had anything to do with the iron door.

The man's expression before he died once again appeared in Mo Chen's mind, and Mo Chen unconsciously looked at the stiff corpse lying on the ground. Before the man died, he stared at the blackboard on the wall so eagerly, there must have been his intentions, could he really be so bored, in order to guide Mo Chen and them, lift the code, release the walking corpses, and kill them all?

Mo Chen and the others had never met a man before this, so naturally they couldn't talk about deep hatred, so why did he harm them so much?

Could it be that the man who just died is the Dr. C they have been looking for? He wants to destroy all mankind?

As soon as this idea came out, Mo Chen himself felt that it didn't make sense, recalling the man's gaze at that time, with a trace of sadness before death, but more regret. It was a huge regret that he hadn't been able to accomplish something until he died, so he guided, hinted, and even please, Mo Chen, a group of strangers, to complete for him, what he didn't do.

Mo Chen approached the man's body, the blood from the man's wound had coagulated, and there was something sticky hanging on the open stomach. Mo Chen picked up the corner of the man's coat and dipped it on the slime on the edge of the man's wound, and the dark yellow viscous material faintly emitted a fishy smell.

The saliva of the walking corpse?

Mo Chen was puzzled, assuming that the man in front of him was Dr. C, then he was killed by the walking corpse he cultivated? Walking corpses, without consciousness, they have no power to move and kill, and aimless killing is their only "mission".

Whether he should trust a stranger has become the only thing Mo Chen thinks about now, should he bet his fate on a stranger?

"Brother!" The attendant screamed in horror.

Mo Chen also noticed that at this time, in a cage not far from Mo Chen and them, there was a thumping sound from inside the iron door, and the walking corpse was about to move.

"Let's do it!" Mo Chen said, "If any of you are worried, I can send you back first, at least the room downstairs is safe for the time being." ”

"Don't tease my brother!" The attendant just wanted to express his opinion for everyone, but seeing Mo Chen's solemn face, he opened his mouth again, "Anyway, where are you and where am I, I won't leave!" ”

Wang Lei on the side, shaking his head, and his stupid appearance has become synonymous with him now. Wang Lei learned the tone of his follower, but with a hint of nervousness, he repeated the words of his follower, "Where are you, where am I~~Where are you, where am I~~"

It sounded like Wang Lei was nervous, but Mo Chen knew that he was expressing his position to himself.

Fang Xiaoxue shrugged her shoulders, as if she was out of the situation, neither leaving nor agreeing.

Dai Min sighed, "Okay! To die together. ”

Mo Chen's gaze swept over everyone's faces one by one, like a soldier's farewell before going to the battlefield. The attendant gave up his position, and the last step of twisting the knob, he hoped that Mo Chen would complete it.

Standing in front of the knob, Mo Chen took a deep breath, whether it is life or death, it is all up to fate.

With a slight flick of the fingertips, the small round shaft of the knob clicked, and only a loud bang could be heard, and the sound of metal rubbing was dry and harsh.

Click......

In the quiet corridor, the sound of the iron door slowly opening was particularly harsh, and for a while, everyone's hearts sank to the bottom.

"I'm sorry, guys!" Mo Chen said with great guilt, the raw black silk threads whizzing on his fingertips, Mo Chen took a step and blocked everyone behind him.

The follower clenched his fists, stood beside Mo Chen, and said righteously, "Good brother, you want to live together, and you want to die together." ”

The tip of Mo Chen's nose was filled with a thick sourness, he didn't expect that in this unpredictable situation of life and death, he could still gain true brotherhood.

Mo Chen rubbed his nose and hummed in a low voice, and then reminded, "Everyone be careful!" ”

Sure enough, as Dai Min was worried, on both sides of the corridor, the iron doors where the walking corpses were imprisoned slowly opened, and rows of black and pressed figures walked out of the door slowly.

The attendant swallowed his saliva unconsciously, and Mo Chen whispered to the attendant, "For a while, you follow me, don't rush forward alone!" ”

At this moment, Dai Min suddenly exclaimed, "Look here! ”
