Gao Zhen's heart tightened, and countless possibilities flashed in his mind, was it a thief in the house? Or did his father come back suddenly? But the other party's figure was weird, which made him scratch his head for a while.

He tensed his nerves and hurried over to look around the living room. Under the coffee table, under the sofa, behind the TV, inside the curtains of the floor-to-ceiling windows, everything was rummaged, but nothing but choking dust was found. How could it be, how could a living person disappear into thin air?

"Brother, look here!" Sister An Lan suddenly shouted, squatting on the ground, pointing to the floor.

Gao Zhen hurriedly went over to take a look, and found that there were some footprints on the ground, which was very messy.

After careful research, the siblings found that there were three footprints on the gray floor. Among them, the footprints of the travel shoes are left by the high pillow, the footprints of the small leather boots are left by An Lan, and there is a kind of footprints that do not belong to the two of them, this kind of footprints are very strange, the soles do not leave any special lines, almost the shape of the feet, like a person who wraps a cloth on his feet.

Gao Zhen looked at his sister, and his sister looked at him, and both of them shook their heads, indicating that they had never seen such shoes at all.

The two men sorted out the strange footprints, and found that the man had come in through the doorway, and had gone out onto the balcony, and then stood at the table and smoked a cigarette, and paced back and forth in the drawing-room, before finally leaving through the door.

"The last to leave through the gate?" Gao asked curiously, he and his sister were standing on this side of the gate, how could they not notice if someone left.

"Brother Ji, didn't you see any weirdos just now? Why didn't you call? Sister An Lan picked up the cat lying comfortably on the sofa, looked into its eyes and asked.

"Meow~~Woo!" Ji Di screamed, and in reply, he broke free from An Lan's grasp, ran to the dining room, jumped on the table, played with the cigarette butts in the ashtray, and treated it as a mouse.

"The wings of the Yellow Crane Tower?" Although Gao Zhen does not smoke, he usually watches Song Tianxi and Lin Haiming smoke, and he still knows a little about the brand of this cigarette.

"Maybe I bought it at Grandma Tian's commissary downstairs." Sister An Lan reminded.

"Xiaolan, let's go down and ask, and by the way, buy some noodles or something to make dinner." Gao Zhen said to his sister that he was not worried about leaving her at home alone, for fear that the strange person would come back.

The younger sister nodded, took her brother's hand, and offered to change the lock of the gate tomorrow to a new one.

……

The commissary downstairs was opened by an old grandmother, selling some tobacco, alcohol, non-staple food, sex toys or something, and I was afraid that it would have a bad impact on my young sister, so I didn't let her in.

"Grandma Tian, did anyone come here to buy cigarettes just now? It is the brand of Yellow Crane Tower spreading its wings. Trezawa asked loudly. This grandmother's commissary was open when Takatsu was a child, and it has been in business until now, and Takatsu knows that her ears are a little back.

"Huh?" Grandma Tian, who was watching TV, heard someone calling her, thinking that there was a customer who was about to check out, but when she looked back, she was sitting high.

"Xiao Gao! You're back? How are you doing in S City? Eh, what about your sister? "When Gao Zhen was a child, he often helped his parents come down to buy things, so Grandma Tian and he knew him very well.

"Well, I'm fine, Xiaolan is waiting outside." Gao Zhen didn't want to talk endlessly with Grandma Tian now, so he asked again: "Did someone just come to buy cigarettes for the Yellow Crane Tower to spread its wings?" ”

"Yellow Crane Tower spreads its wings?" Grandma Tian thought about it, took out a thick blue account book, and looked it up.

"Well, someone did buy a pack this afternoon," Grandma Tian pushed her reading glasses, "Ah, I remembered!" This afternoon, a strange person came to me and bought a pack of Yellow Crane Tower to spread its wings! ”

"Weirdos? What's weird? Taka felt like he had grasped a clue.

"Well, that guy is dressed weirdly!" Grandma Tian remembered it, and the gossip couldn't stop.

"He's wearing a dark dress, a hood, and a mask on his face, and he's just so weird, like you kids...... Oh yes, Batman! Like Batman! The man was fierce and fierce, but he walked without a sound. I was sitting here watching TV, and he suddenly appeared in front of me, without a sound at all. Later, he bought a pack of Yellow Crane Tower to spread its wings, and his voice ......"

"Where did he go?" Gao Zhen interrupted Grandma Tian's endless gossip and asked.

"Later, he ...... He went upstairs! I wondered at the time, I knew all the people who lived in this building, but I had never seen such a person. Dress like you guys! ”

"It's cosplay, grandma." Gao Zhen corrected it, although Grandma Tian still didn't speak English.

……

Seeing that her brother came out with the things she bought, An Lan hugged Brother Ji and greeted him, "Brother, let's go back quickly, I have a bad premonition." ”

"Bad premonition?" Gao Zhen sighed in his heart, his sister was like a natural "soothsayer". Since childhood, her hunch has been very effective.

The two hurried upstairs, walked quickly, and ran home.

Sure enough, as soon as they ran to the corridor on the floor where they lived, Gao Zhen noticed that something was wrong. A can lying quietly in the middle of the corridor was suddenly trampled for no reason! There was only air above it, not a single figure.

"Is it the Invisible?" He yelled and wanted to scare the other party.

Unexpectedly, this "invisible man" was really taken aback and took a step back, "Click! "I stepped on the can again.

"Ji Di! Catch him! An Lan threw Ji Di forward, wanting the cat to catch the invisible man.

"Meow!" Ji Di screamed, and then pounced on the can, and took the can as a rat with a "click" and coiled it.

"Stupid cat!" An Lan stomped her foot angrily.

"Xiao Lan, don't move, I'll chase him!" Gao Zhen saw the footprints left by the invisible man on the ground, and those footprints were moving in the opposite direction. It was clear that the invisible man was running away that way.

"Who are you? Hold it! Gao Zhen chased and shouted after him, but the man ran extremely fast, walking like flying, Gao Zhen only felt that the footprints in front of him were getting farther and farther.

Still, he was chasing after him. Because he knew that there was no staircase at the end of the hallway, and that if he wanted to leave the building, he had to take the staircase that he and his sister had come from. Gao Zhen thought, when the invisible man ran to the end and there was no way out, he would pounce on him and hug him.

Suddenly, Takatsu found that the footprints in front of his eyes had disappeared! The footprints that I had been chasing just now suddenly stopped and disappeared out of thin air!

Gao Zhen was stunned for a moment, and suddenly felt that something big was not good. He hurriedly turned his head and looked behind him. Really! The invisible man's footprints reappeared not far behind him.

"Flash?" It's strange to sit back. This ability to teleport is very similar to the skill of the stalker in the "Reboot II" I played, flashing.

He felt bad and shouted at his sister, "Be careful! "If my sister is caught by the Invisible Man, it will be a big deal.

"What?" My sister was a little far away, and I didn't hear my brother's shouts too clearly. She suddenly felt a gust of wind blow beside her, like a transparent person passing by her, and then the gust of wind blew towards the staircase, and finally disappeared on the staircase, without movement.

"Huhu, Xiaolan, you're not hurt!" Gao Pillow who ran back in a hurry was a little out of breath, he had always stayed in the bedroom to play games, and he didn't exercise much, and after running back and forth in the corridor twice this time, his body was a little unbearable.

"No, I'm fine, the invisible man just now seems to have escaped down the stairs." An Lan walked over and patted her brother's back, who was tired and holding his knees.

"It's a stalker." Gao Zhen said.

"Stalker? What Stalker? Brother, are you playing games again? Mom has said before that she wants you to play less games! An Lan was angry and stopped patting her brother on the back.

"But that person just now looks exactly like the stalker in the game." Gao Zhen said seriously.

"Hey, my brother is stupid." An Lan looked at him with disgust and said.

"Do you know why he didn't touch you just now? This is because the Stalker's passive skill, 'Stealth', will be automatically disabled once it attacks or is attacked. Then he would reveal his appearance, and his identity would be revealed. That's why he didn't attack us and kept stealth. Taka began his analysis.

"Didn't he already show up in front of Grandma Tian?" An Lan asked.

"Well, the cigarettes are all in the cabinet, and he doesn't let Grandma Tian take them, and he can't get them himself." Gao Zhen thought about it and said.

"A second-order stalker, the ninja's skill 'Pranayama' can slow down one's breathing, reduce the noise caused by one's actions, and even suppress one's breath. This skill is used to prevent tracking, and it can also explain why Jidi has never spotted him. He looked at the cat who was still playing with the cans on the floor.

"Then why did he come back? He had slipped through the doorway. My sister asked.

Gao Zhen seemed to think of something, and pulled his sister back home.

As soon as he entered, he ran out onto the balcony and searched carefully.

It didn't take long for him to spot the traces. On the balcony, there was a dusty chair, and there was a circular place on the chair that was vacant, but there was no dust there. It is clear that just recently something round had been placed there and then taken away.

In other words, the invisible man fled in a panic and left something of his on the balcony. So he hid in the hallway, waited for them to go down, came back to deal with it, and when he fled again, he was bumped into by them again.

What could it be that he had taken?

"It's getting interesting, this world." I looked out the window, but the city seemed to be exactly the same as before, unchanged.
