Zhou Yi has been feeling uneasy lately.

Fast Feet and Big Mouth mysteriously disappeared from the satellite orbit two months ago, and their whereabouts remain unknown.

The electric cat partnered with them said that the two Bone Fish had just taken a vacation and were emotionally stable at the time, not committing any accidents or defection.

Satellite images from the Star Axis show both Bone Fish circling the decommissioned satellite Noah-3, and suddenly, the screen turned into static. Two seconds later, when the image returned, they were gone.

The Old King initiated the Star Core Matrix to conduct in-depth calculations and data restoration.

He said, "What can be confirmed is that an ultra-high dose of radiation and energy suddenly erupted from the two Bone Fish, causing surrounding observation equipment and information to be distorted by energy."

"The radiation burst is somewhat related to Noah-3. We investigated its shell and residual data records and found that the satellite showed signs of multiple high-energy radiation exposures."

"Upon internal observation, we also discovered bone structures inside Noah-3."

Zhou Yi was puzzled: "Are you saying that Fast Feet and Big Mouth were modifying this decommissioned satellite with bones?"

"That was our initial hypothesis. To better determine its internal condition, we activated the Sky Patrol Telescope for further observation and analysis."

The Old King transmitted a perspective view of the inside of Noah-3.

The image clearly showed a distinct white skeletal structure inside the decommissioned satellite. Those bones formed a coiled spine, like a compressed figure-eight.

Rather than slowly installing the bones bit by bit, it's more like they were built in from the beginning and then sealed with an outer shell.

Zhou Yi couldn't help but ask, "Have other satellites experienced this?"

"This is the first time in history that bones have been found in an extraterrestrial satellite."

The Old King also took it very seriously: "Based on morphological and skeletal identification, the satellite bones most closely resemble those of snakes. This single bone is highly twisted but shows no signs of fracture or damage."

"But through anatomical atlases and specimen comparisons, we found that it belongs to no known type of snake, nor is it a tail of some large creature."

"After collecting DNA, we found nothing in the gene pool that resembles it. Isotope testing and microstructural analysis yielded the same conclusion: this is the skeleton of a biological entity, but such a creature is one we have never encountered before."

"We could say this is the bone of an unknown species."

Upon hearing this, Zhou Yi already felt the situation becoming somewhat tricky: "Is it a space creature?"

"Uncertain. But creatures with bones typically aren't small."

The Old King said, "Most importantly, based on the final analysis exclusions of the Sky Patrol Telescope and the matrix, we believe this bone wasn't inserted or drilled into from the outside."

"Their shape perfectly fits the lines and shells of various equipment inside the satellite… more like they grew inside the satellite."

Grew bones inside a decommissioned satellite?

Zhou Yi was left dumbfounded.

Could it be that the satellite mutated, transforming from an electronic satellite into a white bone satellite?

The Cat God can communicate directly with each employee's consciousness, and the Bone Fish with the intelligence of a ten-year-old child are no exception.

But this can only happen within a planetary range; beyond the planet where the Cat God is, it's outside the service area, and there's no signal.

The Cat God couldn't get in touch with them either.

With limited and bizarre clues, no entry point was found for further investigation.

The disappearance of the two Bone Fish employees became an unresolved case.

Zhou Yi could only keep an eye on the subsequent developments of the satellite orbit.

He also had to deal with another matter: the Bone Fish expert Wei Ming showed great interest in the Rocket Bone Fish and the Underground Bone Fish after arriving at Sand Port.

Zhou Yi also had two Underground Bone Fish captured from the mantle brought in from 404 City for his reference.

This Panda Man scholar, after some time researching with his assistants, happily approached Zhou Yi.

"Mr. Zhou, we have deciphered the flight secret of the Rocket Bone Fish."

He pointed to several Rocket Bone Fish sunbathing on the shore: "Look, their body structure is quite unique."

The Rocket Bone Fish stood nearly two meters high, resembling a triangular tower assembled from white bones.

"Usually, Bone Fish, when resting, will drill into the ground or seek shelter, trying to curl up their bodies to avoid exposure and attract predatory enemies."

The Panda Man with black-rimmed glasses explained: "But the Rocket Bone Fish are completely different."

He gestured with his thick paws to the Bone Fish's extended bodies: "They try to open their bones as much as possible, facing outward."

Zhou Yi noticed this too.

Indeed, the Rocket Bone Fish resembled small white bone pyramids. They were hollow inside, with their bones flatly expanding to maximize their surface area.

"These bones are neatly arranged. What do they look like to you?"

"Pipes?"

"Yes, exactly, pipes!"

Wei Ming nodded, leaning on a cane: "Their bones are pipes, with flowing Death Light inside. By altering this structure, Death Light circulates within the bones, accumulating energy. Most crucially, there is also something inside helping them."

"Take a look at this."

The Panda Man pointed to the side, where there stood an upright device resembling an old-fashioned pull-string shutter camera.

It had a large lens pointing directly at the Rocket Bone Fish.

Zhou Yi leaned in for a closer look.

The lens had a certain perspective effect, within the skeletons of the Bone Fish, tiny light spots could be seen flickering and moving.

"Is this... the Light Absorption Monster?"

"Mr. Zhou, you understood at a glance."

The Panda Man grinned and said, "Indeed, it is the Light Absorption Monster."

"The Light Absorption Monsters are phototropic to Death Light and also attach themselves to some Guangna Species. They can quickly absorb Death Light Energy. However, they have limited capacity and expel the absorbed energy afterwards."

"But the Rocket Bone Fish utilize this trait. They absorb enough Death Light within themselves, attracting the Light Absorption Monsters. The monsters then concentrate and expel the energy in the opposite direction, creating motion for flight. However, during compression, the Light Absorption Monsters die and disappear, returning to nature."

He gestured with his large paws: "Simply put, the Light Absorption Monsters are the true fuel for the flight of Rocket Bone Fish. Thus, their endurance is short, requiring continuous intake of external Light Absorption Monsters, similar to a Floating Heart needing sugar and oil replenishment."

"Of course, the entire process is much easier on satellite orbits. Because it's closer to the Sun, there are more Light Absorption Monsters; they are a pure energy lifeform."

Zhou Yi nodded as he listened: "So that's how it is. But I never heard the Rocket Bone Fish mention this, they believe they can fly on their own..."

"That's only natural."

The Panda Man chuckled: "Just like humans walk and run and feel it's a given. But in fact, it's the result of the combined actions of nerves, muscles, bones, and blood. Understanding the specifics is often beyond them."

"As for us Panda Men, we have the trait of Longevity, yet we still haven't figured it out ourselves."

Zhou Yi thought: "In other words, the key to long-distance flight of the Rocket Bone Fish is the Light Absorption Monster. Just increase the number they can carry, and the endurance improves."

"Theoretically, that's correct."

Zhou Yi couldn't help but think of a device.

He had previously purchased a device at an exhibition called the [Light Absorbing Monster Collector], from an Alchemist named Ye Si who looked very strong.

This device is specifically for gathering Light Absorption Monsters.

Zhou Yi proposed whether this device could be installed on the Rocket Bone Fish to improve endurance, allowing them to freely explore in satellite orbit.

"I think it's worth a try; theoretically, it's feasible! It's like installing a super Light Absorption Monster battery."

Wei Ming enthusiastically said: "Why don't I try installing it later, what do you think?"

"That would be much appreciated."

With a professional helping with modifications, it would save quite a bit of trouble.

"There's one more thing, regarding the Underground Bone Fish."

At this point, Wei Ming's smile faded: "The two living samples you provided, both have a strength level of B-grade, with a thick layer of minerals as filler between their bones."

"The Underground Bone Fish are very strong. Their structure is fixed and rigid, similar to stone, which makes them suitable for flowing through the viscous mantle, but in the Dead Sea, they become cumbersome and clumsy due to their weight."

"Aside from physical structural differences, they have a unique radiation source inside. Using special micro-perforation technology to enter, and probing with an endoscope, that radiation source carries high temperature and pressure, with extremely high density, likely the core of the Underground Bone Fish's energy circulation system."

"Strangely, these two Underground Bone Fish show almost no intelligence. They don't use unfamiliar tools, despite their high body strength, they remain inactive for long periods."

"This is against common sense. We usually believe that as life strength increases, so does intelligence."

"But the fatal flaw of the Bone Fish is their bone structure itself, which continually wears down, making it difficult for them to retain memories, accumulate experience, and transfer knowledge. However, the Underground Bone Fish don't have this physiological weakness, yet they still exhibit a primitive biological state of life."

Wei Ming adjusted his black-rimmed glasses, speaking slowly: "From these facts, the difficulty in the development of Bone Fish intelligence is not just due to physiological weaknesses, it must be greatly related to their living environment. To date, the only documented intelligent Bone Fish are those your company successfully cultivated."

"They need guidance, to learn how to use tools, participate in the labor and division of social order, enabling them to learn how to think. Otherwise, like the Underground Bone Fish, being strong enough, they don't need to think to survive."

"This may represent the biggest difference between Bone Fish and Bone Men; Bone Men naturally possess social traits and collective inertia. Bone Fish lack this, and thus require post-birth modification and development."

Zhou Yi found it a bit amusing.

Ordinary Bone Fish are too fragile, documenting daily how to gather food, avoid danger, yet forgetting it due to environmental erosion.

The sea floor Bone Fish are strong enough, but they don't need to think to survive in the mantle, so there's no demand for it.

Thus, they are stuck in that situation.

...

Several days later.

A drowsy Zhou Yi was suddenly awakened by the Cat God.

"Chairman, Fast Feet and Big Mouth have returned!"

"They said they saw the Giant Bone Fish, it was the Giant Bone Fish that took them away!"

Zhou Yi abruptly sat up, immediately alert and invigorated.
