The two meal delivery soldiers didn't have keys and USB flash drives, which Chen Mo expected. Because he thinks they can think of what the other party can think of, but the reason for doing so is that they have nothing to do now. In the empty room, they have touched every inch of the wall and floor, and have not found any clues.

As for the other method mentioned by Liu Xuzhong, it is the fish bones and bones quietly left when they eat fish and ribs. As long as they are slightly processed, they can become the key to unlock the lock.

Chen Mo looks at the four monitors and whispers, "there will be no problem with monitoring."

Liu Xuzhong said, "no problem. They let us show our abilities. Even if we know our intention, we won't stop it. "

He turned and walked to the door, inserted a fishbone into it, compared the size and said, "the lock is very deep. There is no lock bullet in it, which is different from the key we see."

The structure of the lock is divided into: lock cylinder, marble, spring and lock tongue, in which the lock marble is the key to unlocking. But Chen Mo is the first time he has heard of a lock without a lock bullet. He goes over and uses a fishbone to reach into the lock hole to feel the structure of the lock. There is really no lock bullet.

That's weird! Moreover, according to his experience, the key shown to them by an officer surnamed Zhao at that time must not match this lock.

What's the purpose?

Wang Xue and Ma Kuan surround themselves and ask how they are. Chen Mo has no choice but to shake his head.

"Shit, we've been locked up for two days and there's no clue. I'm almost driven crazy. I'm dizzy. The lights are on 24 hours. I don't even know it's day and night! "

Looking at Ma Kuan's near collapse, only Wang Xue comforted him. Liu Xuzhong turned and entered the toilet. Soon there was a "crack". He was grinding bones on the edge of the toilet.

Chen Mo takes a look at the monitor, sits down and begins to grind the bones left during dinner on the ground. Although he doesn't know whether he can unlock the lock with the key embryo ground from the bone, he always has to try. If he sits and waits to die, there is no hope at all.

Wang Xue sat down next to Chen Mo and said, "let me come. Close your eyes and have a rest. Staying in the white room for a long time has a great impact on your eyesight. If you have hallucinations, it's not good. Although I can't unlock and steal, I always have to do what I can. "

"We are competitors. Are you not afraid that we will open the door and be eliminated?"

Wang Xue sighed and said, "I'm afraid. But always open the door. I'm not afraid of death. I'm just afraid that my seven-year-old daughter will not be taken care of. "

Seeing Wang Xue's loving mother's appearance makes Chen Mo, who has never enjoyed maternal love, swing in his heart. It's good to have a mother. No matter where he is, there are people who are concerned.

Wang Xue continued, "if I help you leave, can you take care of my daughter after you go out?"

Chen Mo looked at Wang Xue in surprise, but saw her sincere face and said, "before the assessment is over, who will be eliminated is still unknown. Don't lose heart."

"I hope so. Come on, let me help you grind it into the shape of a key? "

"Key embryo." Afraid that Wang Xue didn't understand, he explained: "it's the prototype of the key that hasn't been matched."

"OK."

Give the bone to Wang Xue, and Chen Mo closes his eyes and begins to enjoy the darkness. The friction sound in his ears, like a lullaby, makes him sleep quickly.

When he woke up again, it was time to deliver the meal again. He couldn't remember how many times it was. Only under the reminder of Wang Xue did he know it was the 16th time.

Four days have passed and there are three days left before the deadline.

After dinner, Chen Mo finds that Ma Kuan's eyes are a little dull. He shakes his hand in front of him and doesn't respond. Liu Xuzhong came over, pulled his eyelids and said, "this guy is probably stunned!"

Chen Mo has been to the Bureau. The police used strong light when he was interrogated for the first time. Using strong light during interrogation can increase the physical and psychological pressure of interrogators. At this time, the lights in the room are similar to the means used to interrogate prisoners.

All the lights in the room are incandescent lamps. If you look for a long time, your eyes will be very uncomfortable. The intensity of the light is much lower than that during interrogation, but it takes a long time. It has been four days.

It's easy to collapse in this claustrophobic space for four days. If there were not four people in the room who could talk, I'm afraid they would have died.

"Do you want to ring the bell?" Wang Xue asked nervously.

Chen Mo shook his head and said, "we have no right to make this decision for him. Even if he gives up now, he will only die when he gets out of the room."

"But you can't just let him do this?"

Chen Mo thought for a moment and said, "put him down first and get some water."

Untie the button of Ma Kuan's coat to expose his chest. Wang Xue filled some water with both hands and sprinkled it on Ma Kuan's chest and face respectively. At this time, Ma Kuan's face was pale and his throat made a hurried "ha" sound.

After slapping for a while, Chen Mo picks Ma Kuan up again, while Wang Xue keeps patting him on the back.

Liu Xuzhong disdained and said, "I advise you to forget it. If there are fewer people, there will be fewer competitors."

Wang Xuebai glanced at him and said, "you can't die."

"You can ring the bell for him and let him quit."

"Whether he wants to quit or not needs his own decision."

"Well, you continue to be good people."

Liu Xuzhong tried to insert the key blank ground from the bone into the lock hole, then took out a thread from his clothes to wrap the key blank, put his ear on the door, and turned the key in his hand with a dignified face

Just then, Ma Kuan let out a sigh of "Er", and then cried out, "what are you doing? get out of the way! get out of the way! Don't kill me! "

Ma Kuan got up from the ground and shrunk to the corner. He looked at Chen Mo and Wang Xue in horror and continued to shout: "do you want to kill me and reduce my competitors? Don't think about it! Don't come here, or I'll be rude to you! "

"Calm down, we didn't want to hurt you." Chen Mo explained.

Ma Kuan was stunned, and then shouted, "have you found the key and USB flash disk? Where? Hand it in, it's mine! "

After that, he rushed at Chen Mo and Wang Xue like crazy. Wang Xue screamed and hid behind Chen mo. Chen Mo stretched out his hand and grabbed his wrist, but unexpectedly, the other party opened his mouth and bit him.

Crazy! It's crazy to see it!

He took out a hand and slapped Ma Kuan in the face. Seeing that he was not awake, Ma Kuan immediately appeared red fingerprints on his pale face, and the corners of his mouth were bleeding. He was stunned, and then gave a giggle.

"Pa!"

Another slap in the face!

The slap Chen Mo exhausted all his strength and knocked him to the ground. Ma Kuan struggled a few times and tried to stand up, but failed.

Five or six minutes later, seeing Ma Kuan just crawling on the ground to breathe, Chen Mocai walked over, grabbed one of his arms and said, "wake up!"

Ma Kuan raised his face and said painfully, "we can't pass the examination. They're playing with us. We have only one way to die."

Seeing Ma Kuan finally sober, Chen Mo is ready to drag him to the corner of the wall. When he reaches under each other's armpits, he touches a hard object in his collar.

What's that?

While he was stunned, Liu Xuzhong suddenly shouted happily, "the lock is open! The lock is open! "
