It only took a minute.

The pen skillfully combined the two trivial and complex parts into two wooden dragonflies that looked like miniature versions of helicopter propellers.

"Alright, that's it."

After the combination was completed, the pen Mu Fu smiled and handed one of the wooden dragonflies to Mu Mu who was sitting on the sidelines.

But after Mu Wei got this wooden dragonfly, there was a trace of worry on his face:

"This thing looks like a toy, and it's going to take us into the sky when it's time to fly...... Won't it fall off?"

"Don't worry."

The pen Mu Fu smiled, "This wooden dragonfly, but Mu Fu is the smartest and most intelligent Mu Fu in our Mu Fu Army, and it was invented by the respected great scientist - Super Sense Mu Mu, and there will be absolutely no problems after a long time."

"Feeling mournful? Great scientist?"

Mu Fu said curiously, "The name of this Mu Fu...... Sounds mysterious, isn't he?"

"Of course."

Pen Mu Fu nodded, "Dr. Super Sense was actually the top scientist in his world before he entered the Backrooms.

On that Earth, he worked in Area 51 of the United States of Mingyin, where he was in charge of the Chrono Lab and XCOM Heritage Research Division.

Later, in the process of conducting Philadelphia's cross-time travel experiment, an accident accidentally occurred, which caused Dr. Super Sense to fall into the Backrooms world through the dimensional rift.

At the same time, it was precisely because of coming to the Backrooms that the doctor later transformed into a multi-dimensional super quantum brain, and possessed extraordinary intelligence that completely surpassed that of the human species."

"The United States of Mingyin? District 51? Good guys."

Mu Fu complained, "This ...... It's too much of a sense of sight."

"Huh."

Pen Mu immediately smiled, "I know what you're thinking, Ming Yin United States...... In fact, it's about the same as Millican on the plane you're in.

It's just that the earliest founder of the 'rice country' where Dr. Chaogan lived was not the group of white Puritans of the Mayflower, but the descendants of the crew of Zheng He of the Ming Dynasty."

After talking about this for a while, he got up from the ground and said, "Alright, the small talk is over, we should get out of here."

"I want to know...... Mu Fu raised the wooden dragonfly in his hand, "how should this thing be used?"

"It's easy." Pen Fu raised his hand and placed the wooden dragonfly on top of his head, "Like me, give it a turn."

As he spoke, he raised his other hand, clasped his hands together and grabbed the pole under the wooden dragonfly, and rubbed it gently.

Buzz –

In an instant, the wooden dragonfly above the head of the pen mourning shimmered, magically expanded and transformed, blurring into an illusory light with two wings on its back, wrapping the pen mourning from head to toe.

"It's too black, isn't it?"

Mu Fu complained with a shocked face, "How can you start from a wooden toy...... Suddenly turned into a tokusatsu drama-style light armor? I don't understand it at all!"

"If you don't understand, it's right."

Pen Fu smiled and gave a thumbs up, "This is the greatness of Dr. Super Sense.

By the way, hurry up, I'll wait for you in the sky~"

As he spoke, the pair of two-meter-long light wings behind the light body buzzed and trembled, unfolding an invisible but powerful force field.

As soon as this force field appeared, it propelled him straight into the sky.

Mu Fu, who was still on the ground, saw the same thing, picked up the wooden dragonfly and hung it above his head, and then rubbed his hands together.

Hmmm-

In the blink of an eye, he also became a light-armored warrior, and then, under the voice guidance of the light-clad AI, some of the unskilled anti-gravity fields flew into the sky, flying up ninety degrees towards the end of the heavenly dome.

As the altitude of the flight increases, so does the range of vision.

But no matter how big it was, he couldn't see it

The edge of the giant supermarket below seems to be infinitely large.

In the process of soaring into the sky, Mu Fu was also surprised to discover.

All the concrete pillars in this infinity supermarket are actually like the Carlin Tower in Dragon Ball.

All of them went straight up to the end of the sky, and I didn't know how high they were.

For eight months, Mu Muna's countless air conditioners, which had only heard their voices but not seen them, were mounted in various places on the surface of the concrete columns.

At the same time, the countless fluorescent lights that were emitting blazing light throughout, and then kept the entire Infinity Supermarket below in daylight at all times.

It is the same as the countless air conditioners, and one by one 'grows' like a lotus flower, on the surface of countless concrete columns, at all heights and in all places.

After some exclamation, Mu Fu continued to fly upwards against the cold wind.

After that, under the guidance and auxiliary control of the light AI.

Mu Fu harnessed the anti-gravity field to follow the pen mourning located at a higher place, and flew straight for half an hour at a speed of 200 meters per second, 90 degrees, before finally seeing the end of the sky of this infinite supermarket.

Or rather, its ...... Ceiling.

Anyway, after flying to the highest point of the Xenoworld on this side that I don't know which level of the Backrooms it is.

Mu was stunned and looked up.

I saw an endless expanse...... It is a quiet sky dome composed of countless portals.

This heavenly dome is shrouded in a thin mist, exuding a strange and secluded aura all the time.

Through the mist, Mu Fu could see that the countless rusty old portals above were like countless ancient tombstones, which were both rotten and extremely mysterious.

It's as if behind the portals are hiding dangerous and evil secrets.

And now, they're going to get out of here through these weird portals.

After the rendezvous of pen mourning, Mu mourning was led by him, flying at the lower end of the infinite portal, all the way to the distance.

It wasn't until more than ten minutes later, holding some kind of strange instrument that he continued to search for location, that he stopped under a copper-green portal:

"Finally found it, and it took so much effort every time."

After complaining casually, Bi Fu turned around and waved his hand, signaling Mu Fu behind him to fly over.

Huhuhuhu-

The cold wind howled.

After Mu Fu flew slowly, he looked up at the patina door close at hand in front of him, and suddenly sighed:

"720,000 meters above the ground, if I were alone...... Even if you walk for another 800 months, you won't be able to find this place."

"No need to sigh, the high-altitude area of this big supermarket is far more dangerous than the ground, we need to get out of here quickly."

As he spoke, the pen mourner on the side reached out and grabbed the handle of the patina portal and twisted it vigorously.

Click, click, click

After a muffled sound of gears turning, the portal ...... Stuck.

"!"

Pen Fu angrily scolded, "Drop the chain at the fucking critical moment......

Didi Didi !!

Suddenly, a series of sirens rang out in one of his tactical pockets, and it was extremely harsh.

After the sound of the pen mourning sounded, he hurriedly took out a small device the size of a palm from his pocket that was like a mobile phone.

He looked intently at the screen of the instrument, only to see a message displayed on it:

"Four hundred and seventy-six kilometers away, there is a Knight of the Dead."

After seeing this information, Bi Fu's face turned pale immediately.

"Knight of the Dead?" Mu Wei, who also saw this information next to him, asked curiously, "Is it some kind of entity?"

"Level 4 entity."

The dumb voice with an ugly face on the pen mourning said, "It's a ...... An ugly guy with no skull and a brain, he is fierce by nature and has a megaton of telekinesis."

"Megaton...... One trillion tons

？ What a joke!"

Mu Fu's eyes widened and he stammered, "Doesn't that mean...... With a single thought, it can pull out the whole Tarzan and throw it into the Pacific Ocean?!"

"So before it comes, this door must be opened, or we will all die."

Bi Fu stretched out his hand to push Mu Fu away, Huo Ran stretched out his arms, and after a low shout, dozens of hundreds of pitch-black fountain pens erupted from the wriggling flesh holes in the palms of the left and right hands.

The pens flew through the sky like blackbirds, and at their will, they swirled and condensed into a tornado of pens, rumbling from the bottom to the top and slamming into the bronze door.

Boom!!

Zizizizizi!

For a moment, the sound of violent friction was intertwined with red sparks, covering an area of tens of meters centered on the bronze portal.

But after a full half a minute of 'drilling', the bronze portal was only slightly dented, and it was not pierced at all.

"Damn, although my metamorphosis ability is good at dealing with biological organisms, it is not good for this high-strength alloy door...... I can't do it." Pen Fu gritted his teeth and cursed.

"So what now?" Mu Fu asked anxiously on the side.

"I want to ...... We'd better go back to the surface and hide first." Pen Fu sighed, "When the Dead Knight is far away, we'll come back and figure out a way."

"This ...... Okay." Mu Fu was helpless, "Now it seems that this is the only way."

Just when the two of them were a little discouraged and wanted to leave, the bronze door was pushed open from the inside.

Click!

A somber man wearing a black jacket and sunglasses appeared inside the bronze portal.

"Spider-eyed mourning?"

Pen Fu was surprised and delighted, "Why are you here?!"

"Don't talk nonsense."

Inside the bronze door, Spider Eye Mu Mu squatted on the side of the door frame and looked down at the two of them, and said coldly, "Come in."

「oKoK。」

Bi Fu nodded again and again, beckoned Mu Fu behind him, and flew into the door with a bang.

Boom!

After the two of them entered, the thick bronze door was kicked up from the inside by Spider Eyes, and after a gear click, it was completely closed.

After a few minutes, the bronze door and the millions or even billions of portals of various shapes around it suddenly blurred and deformed, turning into an endless stainless steel sky.

Obviously, these portals to various unknown Backrooms levels have all randomly 'migrated' to other celestial vaults under the influence of some mysterious mechanism of the Infinity Supermarket.

I don't know how many years it will take for the next time the portals return from their 'migration' again.

However, these have nothing to do with mourning and writing.

Because, at this moment, they have arrived at the other side of the Backrooms space.

And just five minutes after Mu Fu and the others left......

Rumble!!!

Suddenly, an invisible force that was majestic and huge enough to crush the mountains suddenly descended, instantly tearing apart this piece of stainless steel sky that was hundreds of miles long.

The resulting stream of scorching red iron rumbled like a rain of fire over the countless concrete columns below, as well as the even larger expanse of ground below.

In a time, countless towering containers were burned to the ground and burned into countless ashes in the billowing smoke.

At this time.

"Roaring !!"

In the roar of tearing the earth and the earth, a pitch-black giant horse with six wings up to 100 meters long appeared in the sky and galloped towards it.

The black horse galloping through the sky was hollow at the waist, and within it was a heavily armored knight with only the upper body and a shield in his left hand and a spear in his right.

And at the knight's rusty, broken helmet, there was a blood-red brain that vibrated and shimmered all the time.

One terrifying mental power after another continued to erupt from this brain

And out, tearing and squeezing all kinds of things big and small within dozens or hundreds of miles around it.

That's right, this monster that is a combination of humans and horses is a level 4 entity Death Knight.

Unfortunately, no matter how angry it was at the moment, it was useless.

The prey has fled and cannot be pursued.

Therefore, the Death Knight vented for a long time, and finally had no choice but to leave here and fly towards another distant sky.

……

The desolate and dilapidated amusement park was completely shrouded in the terrible darkness of the night, without a trace of human habitation or light.

At that moment, under a huge Ferris wheel that had been dormant for a long time, there was a row of filthy green garbage cans, three of which ...... Suddenly, there was a violent tremor.

In the next second, the three of Bi Fu, Mu Fu and Spider Fu each got out of the three stinky trash cans.

"Gwoon~"

As soon as Mu Wei got out of the trash can, he lay on the ground and retched, complaining while vomiting, "It stinks! Stinks to death! This backroom is a psychopath, why does the space-time corridor come out of the trash can at the end?"

"Oh, it's rare and weird." Spider smiled coldly, "I once came out of the toilet bowl of the public toilet."

「……」

Mu Fu immediately stopped throwing up, and at the same time gave a thumbs up and praised, "You are awesome."

"The theme of this amusement park's backrooms level is all about trickery and banter."

Pen Fu patted the dirty dust on his body indifferently and explained, "So its 'holes' will always appear randomly in some places that make people laugh, like I ...... once."

"Don't talk nonsense." Spider Fu said coldly, "Take him to the captain."

After saying that, he hurried to the depths of the amusement park with his hands in his pockets, and gradually disappeared into the darkness.

Looking at the other party's distant back, Mu Fu turned his head and asked Bi Fu, "Why is he so stubborn?"

"It's better than me, anyway." Pen Fu shrugged and smiled, "If he is allowed to return to the real world, he can destroy a regiment of troops by himself."

"So powerful?! Oh yes."

Mu Fu seemed to remember something, and asked Bi Fu again, "I want to ask, what kind of superpower do you have...... Where did it all come from?"
