◎The room number we are looking for should be...◎

Everything in front of him seemed to be in slow motion, infinitely magnified in front of the octopus man's face.

Rong Xiao's fist looks like a soft sandbag, and its attack power can be -

"ah!!"

Pitiful screams echoed throughout the house. The person who was originally entangled by the tentacles fell back to the ground. Shangguan Yu, who had flown far away from the window, also moved back and lay on the window to join in the fun.

Not to mention Shangguan Yu who was far away, even Shangguan Huai who was closest to him didn't see clearly how Rong Xiao hit the octopus man's eyes.

All she saw was the person moving quickly, using the tentacles that were trying to attack her as steps, and nimbly jumping into the air. The next second, the octopus man covered his eyes and screamed.

The speed of the punch was as if it was cut out of the screen, so fast that there was no time to see it clearly.

Rong Xiao's seemingly harmless fist made the Octopus Man's eye sockets red, swollen and purple. It hurt so much that he couldn't open his eyes. He could only cover his eyes and crawl towards the entrance instinctively.

"Hey? Why are the tentacles gone?" Shangguan Huai's butt hurt from shaking, and he climbed up with his hands covering his tailbone and making a face.

Shangguan Yu knocked on the window frame. "Because his eyes are injured, he can't create tentacles. I flew out of the window. It was too bright outside, so the room looked even darker, and I could see more clearly. Every time a tentacle appeared, his eyes would glow and flicker."

Shangguan Yu's analysis made the Octopus Man feel uneasy. After his confident advantage was exposed, he felt like he was thrown naked into the street. He was also punched in the eye, which was so swollen that he could only see a slit.

"Yuan Yi, what are you looking at? Why don't you come and help me?!" The octopus man was in so much pain that he couldn't open his eyes. Everything he saw was blurry and black. He scratched around everywhere and finally touched a cold hand.

The hand was just lent to him for support, with no intention of holding him and saving him. The octopus man quickly pinched his wrist and determined that it was his companion by the familiar smell.

"I told you, it was you who was careless. Even if you died, I wouldn't help you collect your body. You caused this yourself, so you have to bear the consequences."

Seeing his companions suffer a crushing defeat, Yuan Yi remained calm. He walked out of the house with the octopus man as if he was taking Mr. Lagerfeld to stroll around the back garden, and walked leisurely towards the stairs.

"Just let it go like that?"

"Why don't you go and take a look?" Shangguan Yu deliberately said something sarcastic.

Tian Yichuang didn't realize the sarcasm and created a fireball to attack the fallen dog.

When he opened the door and rushed out of the room, opened the door -

Crackle.

What sound?

The fleeing figure stopped more than ten meters away, looking at this side leisurely, as if it had achieved its goal and was no longer planning to escape.

Crackle!

A sound similar to a strong electric shock was right next to me.

But Tian Yichuang looked sideways several times and didn't see anyone!

Could it be that I'm so unlucky as to encounter someone with lightning abilities?

"Don't touch the metal." Shangguan Yu didn't touch the door handle, but kicked the wooden door and slowly opened it.

"It seems we haven't lost yet," Yuan Yi supported the octopus man and smiled at them, "We have a lightning-type mutant on our team!"

What you fear will come true.

In the end times, there are very few people with awakened lightning abilities. As a result, I encountered two of them in a row in the past two days. The rare abilities have lost their preciousness, like they are sold wholesale in the vegetable market.

"Lightning ability..." Rong Xiao muttered repeatedly, his fingers trembling with joy.

Shangguan Yu saw what she was thinking and raised his hand to push her head: "He is a bad guy, there is no way he can charge your phone."

"Oh, what if we catch him and force him to charge us?" Rong Xiao touched her head. Her shocking words made everyone who once thought she was naive and kind look at her in new light.

What about the confiscated power banks?

Crackle!

The sound of electric current rang out again, and the fire in Tian Yichuang's hand was extinguished in fear. He nervously determined the distance between himself and the surrounding metal. There was even a flash of electricity on the metal guardrail next to him.

A figure slowly walked out from the stairs. He had an indifferent expression, his hands in his trouser pockets, looking at the group of people opposite with disdain. His eyes were narrow, and it was unclear whether he could not open them or they were just that small.

He looked at people with such eyes, which could easily provoke the anger of his opponents.

"Useless thing," the squinting man was not one to be trifled with, scolding the octopus man mercilessly. "You can't even complete such a small task. It's really shameful. You might as well not go back."

“…” The octopus man didn’t dare to talk back and kept his head down like a quail.

"Okay, okay, he's already very pitiful. Let's resolve the matter as soon as possible and go back as soon as possible." Yuan Yi's style was completely different from the other two. He looked like a gentle person who was easy to talk to, but he did not stop his companions from doing some evil things.

He seemed to be trying to stay out of it, but not to appear too alienated from others, as if maintaining a basic distance with a thin line.

He snorted coldly with narrowed eyes and turned his head, looking sharply at the opposite side, throwing a metal-plated ball in his hand.

Shangguan Yu quickly pulled Shangguan Huai away: "Be careful!"

As soon as he finished speaking, he raised the metal ball in his hand and threw it out. The ball was connected to flashes of electric light and flew towards them. It was fast, fierce and charged. Whoever touched it would be doomed.

If this was an ordinary ball, Rong Xiao, Long Qingyu and Tian Yichuang could all deal with it.

But this ball was electrified, and the electric tail at the end was connected to the lightning-type mutant with squinty eyes.

Afraid that Rong Xiaofei would be too brave to catch the ball, Long Qingyu grabbed her first and nimbly pushed her sideways to avoid it.

There is an electrified ball in front of him that is about to hit him, and there is an electrified metal guardrail behind him, and the crisis is sandwiched between them.

Boom——

The ground beneath their feet cracked with a loud noise, rising up to form a wall as tall as a person blocking their way.

The flying ball hit the stone wall, making a small hole, and then rolled along the gap to the fifth floor.

Mimi was slightly stunned and looked at Yuan Yi beside her in surprise, her eyes clearly questioning what was going on.

"I don't know. It should be a mutant we haven't discovered yet," Yuan Yi paused and emphasized, "an earth-type mutant."

The angry squinting man raised his hand and slapped the octopus man: "Didn't you say that there were only these few people? How come there's an earth-type mutant now?"

The octopus man held his head in his hands pitifully: "They are the only ones I know about, there is no one else."

"Don't blame him. I didn't find another psychic either." Yuan Yi looked at the other side meaningfully. "It seems they were well prepared and left one team member to act separately."

Long Qingyu and others were equally confused and had a lot of questions in their heads.

Is there an earth-type mutant in their team?

How come they don’t know it themselves!

There was a rumbling sound on the floor, and the ground under Mimiyan's feet suddenly tilted down, sliding the three of them to the fifth floor like a skateboard.

The next second, the floor on the fifth floor broke and tilted in the same way, causing people to slide all the way to the first floor.

The people upstairs didn't know how to react. They watched the three people who had been so cool just now being transported all the way downstairs like poop flushed down the toilet.

"Escaped?" Tian Yichuang asked uncertainly.

Shangguan Yu squinted his eyes and looked at them with disdain: "Obviously not, someone is secretly helping us. They are clearly in an advantageous position, why would they run away?"

The ground that was erected in front of them returned to normal layer by layer.

The door in the next room opened a crack, and a teenager came out. "Hurry up, what are you standing there for? Are you waiting for them to come back?"

"Just now... were you the one who helped us?" Shangguan Huai asked curiously.

The boy glanced at him and said, "Nonsense, who else could it be besides me?"

"Thanks……"

"No need to thank me, just pretend you haven't seen me. Go your separate ways." The young man waved his hand and ran forward, disappearing at the stairs in a blink of an eye.

"What a weird guy," Tian Yichuan, who wanted to shake hands with the other party, wiped his hands on his trouser legs and put them back in his pockets. "Don't worry about him. Let's finish the task quickly and leave before they come up."

"That's not right." Shangguan Yu said suddenly.

"What's wrong?"

"That number is not a house number."

"ah?"

Shangguan Yu’s words were like a heavy mountain pressing down on me, making it hard to breathe.

"but……"

Ling Xi covered her chest and protested vehemently: "Shangguan, please stop panting and talking!"

"Who made you so emotional so quickly? I didn't say I didn't know," Shangguan Yu stroked his chin, staring at the pale wall as if he was standing still as if he was being punished. "Don't talk, don't disturb me."

“…”

No one dared to speak. Shangguan Huai was even afraid that his breathing would disturb him, so he covered his mouth and tried to hold his breath.

Several pairs of eyes were fixed on Shangguan Yu with eager anticipation.

"The room number we're looking for should be 6174."

"Why?!"

"The system's hint wasn't just that number. There were other things as well. Did you eat them?" Shangguan Yu took the lead, followed by a trail of followers. "The black hole and the number—these two are very clear hints."

During the explanation and analysis process, Shangguan Yu took the time to look behind him. Those pairs of eyes were filled with the same confusion.

“Have you heard of a digital black hole?”

"Numbers and black holes? What the hell?"

Shangguan Yu: “…” Suddenly I didn’t want to explain anymore, it was too troublesome.

"Hurry up and tell us, we don't know if you can explain it to us." Tian Yichuang patted Shangguan Yu's shoulder with confidence, causing his thin body to sway left and right.

Ruthlessly pushing his palm away, Shangguan Yu spoke with his last remaining patience, "Choose any four digits, all of which are different. Arrange them from largest to smallest to form a four-digit number. Then, arrange them from smallest to largest to form another four-digit number. Subtract the latter from the former to form a new four-digit number. Repeat this process, and you will get a number within seven steps—6174."

"So, 6174 is the house number we are looking for? But this number sounds weird. Is there really such a house number?" Shangguan Huai turned his head and looked behind him. The house number behind him was 6081. According to the usual numbering method, it looked weird no matter how he looked at it.

"We came up the stairs, didn't we?"

"yes."

"Actually, the house numbering system is indeed different from what we're used to, but it's not difficult to analyze," Shangguan Yu led the way to the other side. "The first digit, 6, represents the floor. The second digit should be 1 and 0. The room on the left corridor after exiting the elevator is 0, and the room on the right corridor is 1. The third digit represents the order of the rooms once you're standing in that corridor."

"As for the last digit..." Shangguan Yu pointed at the number on one of the house numbers, "Someone come and pry open the last two digits and compare them, and you'll know."
