"Yingchen is not in the corridor on the fourth floor. He must be hiding in a room. He is probably keeping an eye on his surroundings."

"This guy doesn't dare to play by the rules. His style of doing things is weird. I have to be more cautious."

Chen Ge didn't know whether Ying Chen had obtained any information about himself from the middle-aged man. He didn't care about that. He thought that while Ying Chen didn't move, he should go and see Miss Hong and try to find as many helpers as possible.

With the help of the lady in the skirt, Chen Ge came to the corner of the stairs between the fourth and fifth floors. There was a faint stench in the air, and there were some water stains under his shoes.

"Why did you stop suddenly?" Chen Ge asked in a low voice. He was walking up, but the lady in the skirt who was supporting his arm suddenly stopped moving.

Chen Ge couldn't see anything. After noticing something unusual about the lady in the skirt, he immediately became nervous.

I could vaguely hear a girl's singing, as if it came from a broken music box, intermittently, and the voice was so strange that it was indescribable.

"Is anyone coming? Go to the fifth floor first, don't stay here!" Chen Ge had a bad feeling. He could tell that the singing came from the fifth floor, and he was worried that the sound would attract Yingchen over.

"Someone just walked past the fifth floor, and there was no sound at all." The lady in the skirt said in a strange tone: "Did I see it wrong?"

"Wait a minute! Music box? Girl's singing? A figure walking silently? Could it be Ying Tong you just saw?" Chen Ge knew that in reality there was a broken music box on the table in Ying Tong's bedroom.

"Should we chase after him?" the woman asked.

"No, something is wrong." Chen Ge's fingers gripped the backpack more tightly. "If I were Ying Tong, I would definitely not let the music box make any sound when I escape. Isn't this deliberately exposing my position?"

"It's also possible that he accidentally touched the music box, causing it to suddenly sound."

"I've been to Ying Chen's house. The music box was placed in Ying Tong's bedroom. If Ying Tong didn't go home in the meantime, the person holding the music box must not be Ying Tong!" Chen Ge broke out in a cold sweat: "There is another person in the building helping Ying Chen! He was the one walking around with the music box to attract attention! That bastard may have guessed that someone else is looking for Ying Tong!"

Yingchen is very smart, but Chen Ge is also very perceptive, and both sides can discover problems from extremely small details.

"Do you know anyone in this building who has a particularly good relationship with Yingchen? Someone Yingchen can trust unconditionally?"

"There are many residents who have a good relationship with Yingchen. By the way, Yingchen is very popular with children, and children are willing to play with him."

"Like by kids?"

"Well, Yingchen has a good personality. He also likes to play games with children and occasionally buys toys and candies for them."

"Was that figure that just passed by a child?"

"A bit like him. He's very short and makes no sound when he walks. I almost thought I was seeing things." The woman took a breath and slowly realized that the residential building tonight was a little different from usual. "Should we still go to the sixth floor?"

"Of course I will go, but when you pass the fifth floor, pay attention to see if there are other people in the corridor." Chen Ge squatted down and touched the water stains on the ground: "The water stains are almost dry. It doesn't look like Yingchen deliberately sprinkled water to preserve shoe prints."

"You are too careful. Maybe Aunt Wu just cleaned it."

"How can you be sure that it was Aunt Wu who cleaned the house?" Chen Ge heard a new name from the woman's mouth - Aunt Wu.

"She is the cleaner of our building. She is very responsible and cleans the whole building every morning and evening." The lady in the skirt said casually, "You don't suspect that Aunt Wu is helping Yingchen, do you?"

Chen Ge didn't say anything, he was thinking about something else.

Although the community where Ying Chen and Ying Tong live is very shabby now, it was the most luxurious community in the old city many years ago. This can be seen from the fact that the building was equipped with an elevator so early on.

Aunt Wu is responsible for cleaning the building, which is not a big deal. The problem is that she also appeared in the world behind Ying Tong's door. This cleaning lady may have been killed by Ying Tong in reality, just like the lady in the skirt and Mr. Wood.

But there is another possibility. Aunt Wu may have done something to Yingtong that left a deep impression on him.

Chen Ge had many guesses in his mind. It was possible that Aunt Wu had helped Ying Tong escape, or that she was the one who tipped off Ying Chen.

"What is the relationship between Aunt Wu and Ying Chen?"

"Very bad. Aunt Wu often quarrels with Ying Chen. She hates cats and thinks Ying Tong always picks up dirty stray cats, which increases her workload of cleaning." The woman added after a while: "By the way, during a private chat, Aunt Wu said that Ying Chen smelled sour, like cat meat that had been left for a long time."

Chen Ge's brain was working rapidly, and he connected the known information together. "This place has just been cleaned, which means Aunt Wu has been here before. The short figure holding the music box that appeared right after Aunt Wu, the music box is in Ying Chen's house. I guess Ying Chen asked the short figure to use the music box to test Aunt Wu. Ying Chen suspected that the person who entered his house was Aunt Wu!"

"Although I didn't quite understand what you said, I feel like what you said makes sense." The lady in the skirt found that Chen Ge's words were very logical, at least that's what she thought at first glance.

"Yingchen doesn't know about my existence, so it's normal for him to doubt Aunt Wu." The world behind the door is woven according to Ying Tong's memories. The rules that govern this world are Ying Tong's memories. If Ying Tong wants to escape, the only things he can use are the people and things in his memory. But on this day, Chen Ge entered the world behind the door, and he was the only outlier.

While the two sides were communicating, they had already reached the fifth floor. The floor here was a bit slippery, and Aunt Wu had just cleaned it.

"There's no one in the corridor on the fifth floor. Shall we go to the sixth floor?"

"Don't be anxious. Check the ground to see if there are any shoe prints. Look carefully." Chen Ge pressed his body against the wall. He had basically adapted to the darkness and had overcome the physiological discomfort.

"Shoe prints?" The woman let go of Chen Ge's arm. She seemed to go into the corridor and take a look: "There really are some!"

"Keep your voice down. How many shoe prints are there on the ground?"

"This shoe print should be from Aunt Wu, she likes to wear cloth shoes, and the other sandal shoe print may be from the children in the building."

"It seems that our guess is correct. Look at the direction of the toe of the shoe prints and judge where they went." Chen Ge couldn't see, so he could only rely on the lady in the skirt for help.

"Auntie Wu has more shoe prints. She seemed to have been lingering at the door of the cleaning cabinet for a long time, probably to get tools. The other sandal prints were all pointing in one direction. The owner of the shoe prints should have been following Auntie Wu." The woman added, "There is no one on the fifth floor now. Could they have gone to the sixth floor?"

"Wandering around the cleaning cabinet? Aren't the utility rooms prepared for cleaning staff normally on the first floor? Wouldn't it be inconvenient to put their cleaning tools on the fifth floor?" Chen Ge recalled the scene when he went to Ying Chen's house. He had the impression that there was no cleaning cabinet on the fifth floor.

"The developer seems to be preparing to build a model community, and has the property management prepare cleaning cabinets for each floor owner, which contain daily cleaning tools, ropes and fire-fighting equipment."

"It sounds like there's nothing wrong with it, but why did Aunt Wu stay in front of this cleaning cabinet on the fifth floor?" Chen Ge grabbed the woman's arm and asked, "Is that cleaning cabinet locked?"

"No."

"Go and open the door. I suspect Aunt Wu may have hidden something in the cleaning cabinet."

The woman helped Chen Ge walk to the cleaning cabinet. She gently pulled the cabinet door and said, "Huh?"

"What's wrong?"

"It can't be opened. It seems like something is stuck inside."

"It's not locked and can't be opened?" Chen Ge suddenly thought of something. He whispered to the cleaning cabinet, "Ying Tong? Are you in there? I know your brother is a perverted murderer who likes to torture cats. I'm here to help you escape from this building!"

"What are you talking about?" Just as the lady in the skirt finished saying this, there was a slight sound from the cleaning cabinet, as if someone had taken something off the top door. "Who's in there?"

The door opened and the lady in the skirt took a breath.

"What did you see? Tell me about it," Chen Ge urged in a low voice.

"Ying, Yingtong is shrinking in the closet! How could he be hiding here!" The woman was very surprised and her voice became a little louder.

"Ying Tong?" Although Chen Ge was mentally prepared, he knew that Ying Tong must be hiding somewhere in this building, but he never expected to meet her so early: "It seems that I am lucky this time."

"Who... are you? Did Aunt Wu tell you that I was here?" Ying Tong's voice was a little numb, like a robot, without a trace of emotion.

"I'm here to help you leave. I know your brother's true face, and he will definitely get the punishment he deserves." Chen Ge took a step forward, his hand touched Ying Tong's shoulder, he gently stroked Ying Tong's face with his fingers, and his fingertips touched the uneven scar.

"Do I look scary?" Ying Tong's voice came from in front of Chen Ge.

"I am blind and cannot see your appearance, but I know you have a strong and kind heart and a very smart and calm brain."

If an ordinary child encountered a situation like Ying Tong, he would probably have gone crazy long ago, but Ying Tong did not. He kept looking for opportunities to escape and never gave up.

Although the two brothers have very different personalities, they are both very smart. In a sense, it can also be said that both of them are scary.

Chen Ge remembered Ying Tong's appearance. In order to gain Ying Tong's trust, he grabbed Ying Tong's hand and placed it on his face: "My name is Chen Ge. From now on, you are no longer alone. No matter what the final result is, I will always be with you."

No one has ever said this to Ying Tong. Aunt Wu should be helping Ying Tong secretly, but she doesn't dare to give Ying Tong any guarantees.

Chen Ge touched Ying Tong's face with both hands, and also touched what Ying Tong was holding. The child was carrying a large bag with a ball-shaped object and something that looked like a flashlight in it.

"What's in your bag?"

"Aunt Wu didn't believe what I said, so I showed her something and she believed it."

"What?"

"A football made by my brother."

There was a rustling sound in her ears. Ying Tong opened the bag and the lady in the skirt looked into the bag curiously.

“Heads!”

Fear filled her heart, and the lady in the skirt was frightened at that moment, and the sound she made was a little loud.

"Keep your voice down! We can't stay here, let's go to the sixth floor immediately! Let Ying Tong meet A Ying!" All of Chen Ge's guesses will be proven when Ying Tong meets A Ying, and he is now a little impatient.

The lady in the skirt supported Chen Ge and Ying Tong on the left and right, and the three of them re-entered the corridor. But just when they reached the corner of the fifth and sixth floors, the old elevator on the floor suddenly made a sound.

"The elevator started! Someone took the elevator upstairs! Was it because Yingchen heard the sound?"

The word "human head" was too clear, and Chen Ge was a little worried now.

He stopped and his face gradually became ugly. The elevator stopped on the fifth floor, and then a faint cat's meow was heard.

"It's Yingchen!"

The cat's meow did not suddenly become louder, so Yingchen should still be near the elevator, but it is certain that he has reached the fifth floor.

"hurry up."

It was easy for three people to make noise when together, but Chen Ge had no better solution now and could only stay away from them as much as possible.

"Go to Miss Hong's house and hide there first!"

The cat's meowing sound did not change. The lady in the skirt helped Ying Tong and Chen Ge to the sixth floor. They stopped in front of Miss Hong's room.

"Don't knock on the door to prevent any noise. Call her or send her a message and ask her to open the door."

“But I didn’t bring my cell phone.”

While the two were talking, the sound of a girl singing was heard from the corridor on the other side, and the person holding the broken music box went upstairs!

The cat's meow could warn Yingchen, but it couldn't warn others. There were Yingchen's helpers in the building, which was a very bad thing for Chen Ge who couldn't see anything.

"what to do?"

Time was running out, and there was a 50% chance that the knock on the door would attract Ying Chen. If Miss Hong was slow to open the door, Chen Ge and the others would most likely be caught by Ying Chen, and Ying Chen's helpers were also heading this way.

"Retreat to the left corridor first." The plan had to be changed. When Chen Ge and his companions were walking towards the left corridor, a cat's meow suddenly sounded, and the distance between Yingchen and them was slowly closing!

"That guy heard the noise just now!" Chen Ge gritted his teeth. He found Ying Chen to be really difficult to deal with. He had suffered a loss before from this bastard, so this time he specially found someone to go upstairs with him, one on the left and one on the right. No matter which corridor he entered, he would be seen! !

The sound of cats' meows came into their ears, and the sound gradually became distorted and harsh. The three of them were now standing at the entrance of the corridor on the left side of the sixth floor, and Yingchen might be in the corridor at this moment.

"I made the sound. He should only look for me. You go to the seventh floor and hide first. I'll go and stop Ying Chen." The lady in the skirt took the initiative to enter the corridor and walked towards the fifth floor. Chen Ge also entered the corridor holding Ying Tong's hand, but he and Ying Tong walked quietly to the seventh floor.
