The heavy iron gate kept those people out, and they would never rush in.

Ryoko ran inside in a hurry, because this floor was where Chihiro was held.

Lei Kun looked at this place and felt that this place was not like a prison for people at all, but like a laboratory.

The people in the rooms on both sides of the passage were the test subjects.

Lei Kun looked through the glass on the door, which was only ten centimeters long and seven centimeters high.

Here is a big man from the United States, although he looks physically strong, but now he looks sluggish.

Lei Kun shook his head and continued to walk towards the next room.

The people in it were obviously much more "lively", and they looked extremely excited, rolling back and forth in this fifteen or sixteen square meter room, and their mouths were open, as if they were shouting something angrily, but Lei Kun didn't hear a sound.

Lei Kun didn't know if this person didn't make a sound at all, or if the sound insulation of this room was too good, so he knocked on the glass gently.

The person imprisoned in the room suddenly stopped, and he slowly looked in the direction of Lei Kun.

He was stunned for a few seconds, his eyes suddenly becoming irritable, but after a while, he hid in bed and shivered.

Lei Kun was a little confused, so he could only look towards the next room.

But after looking at several rooms in a row, he felt that the people here were a little abnormal, either static or moving, crazy or crazy, and in the end, Lei Kun could only think that these people had been imprisoned here for too long, and their spirits were already abnormal.

At this moment, Ryoko suddenly found the room where Chihiro was being held, and she suddenly exclaimed, followed by tears in her eyes.

Lei Kun didn't care about her, after all, the passage above it has been sealed now, so their time can be said to be too much.

As he slowly walked to Chihiro's detention room, he inadvertently saw a person being held in the room next to her.

When Lei Kun saw this person, he suddenly laughed.

Because what is being imprisoned here is the ancient book that has died in Baihuizi's mouth.

So he tapped lightly on the glass.

Furumoto in the room struggled to look up when he heard the voice.

When he saw Lei Kun, his eyes were full of incredulity, especially when he saw the smile in Lei Kun's eyes, his heart suddenly "chuckled".

He supported his body with his hands, slowly walked down from the bed, and then moved his feet to the opposite side of Lei Kun.

Gumoto was stunned for a few seconds, then desperately slapped the glass and shouted something.

But Lei Kun couldn't hear a word, so he pointed to his ear and shook his head again.

Gumoto seemed to remember something at this time, and sighed on the glass, writing something on it with his fingers.

When he finished writing, Lei Kun saw only two words on the glass, "Help me." ”

Lei Kun also wrote on the glass, "Why? ”

"Rings."

Lei Kun hesitated, and then he wrote, "I want to know about Baihuizi. ”

"No problem."

"Okay, wait." After leaving these three words, Lei Kun walked towards Ryoko.

He looked at Ryoko, "Do you have the key here?" ”

"Nope."

"Then how are you going to rescue Chihiro?"

"This ...... I don't know at the moment. Ryoko's voice grew weaker and weaker.

"You came to save people without preparing anything?" Lei Kun asked incredulously.

Ryoko was silent, but she kept her eyes on Chihiro and said in a firm tone, "I will definitely rescue her." ”

Ryoko then left a message on the glass in the same way, "I'll find a way to get you out." ”

Then he began to look down at the lock that held Chihiro, and said, "I don't know what kind of lock it is, but I studied various locks before I came, and I will definitely find a way." ”

"Good luck then." Lei Kun began to think of other ways.

Ryoko looked anxious, obviously it was not easy to open the lock, but in order to save Chihiro, she did not give up.

At this time, Lei Kun also began to think of other ways to open the lock, but this put him in a predicament.

But he soon remembered that the man he had been talking to had suddenly disappeared.

This surprised Lei Kun, and he looked around, and there was indeed a monitor installed on it, so the mysterious person could still monitor their every move.

He walked through the passage and knew that there were ten monitors on it, so the mysterious man would definitely see them too.

But why the mysterious man suddenly disappeared at this time made him a little suspicious.

At this moment, Murano came to Lei Kun's side and whispered, "Do you have the key to open the prison room?" ”

Lei Kun shrugged, "This door lock is not so easy to open. ”

Then he glanced at Ryoko, "I hope she can open it." ”

Murano also sighed at this time, and then turned around silently, thinking of a way to unlock the lock.

At the moment when Murano turned around, Lei Kun suddenly had an idea, since the mysterious man can monitor their every move, and can also control the door locks on the underground floors, the mysterious man must be not far from here.

When he thought of this, he made his spirit flutter and hurriedly searched for the location of the mysterious man.

He then began to search room by room, but he looked at more than a dozen rooms in a row, but he did not find any clues.

Just as he was about to give up, he suddenly found that the door to the last room was made of an iron plate directly embedded in the door.

And Lei Kun knocked hard, but no sound came out, which made Lei Kun sure that there was no one in this last room.

"It seems that this room is really unusual." So he pushed the door hard, but it didn't move.

"Could it be that this door is also locked?" Lei Kun muttered to himself.

But he also knew that if the mysterious man was really here, he would never have completely closed the door.

He immediately shouted at Ryoko, "Ryoko, look at this lock, how long it will take to open it." ”

Ryoko glanced back, then came over again to take a closer look, "Three minutes." ”

"Open this lock first."

"This is ......" Ryoko looked at Lei Kun suspiciously.

Lei Kun could only tell Ryoko his thoughts, and at the same time said, "There must be important clues in this." ”

Ryoko looked at Lei's solemn expression, and although she had some doubts in her heart, she also began to try to open the door lock.

As she tried to open the lock, she muttered, "This lock doesn't seem to be the same as the previous ones, it seems...... Much simpler. ”
