"What you mean is... this situation is somewhat unpredictable..."

It was struggling to find the right words but eventually gave up and said directly, "It's like this, a three-member family doesn't refer to three individuals, but three species."

"Later, a four-member family emerged, which included mechanical lifeforms. They believe this is the trend for the future and are happy to become the family caretakers, responsible for finances, daily planning, and other tasks requiring precise calculation."

Zhou Yi asked, "Are the mechanical lifeforms in the family working locally via remote branches?"

"Yes."

That's good.

Mechanical lifeforms are inherently suited for home office settings, and their work efficiency remains unaffected.

"What about a five-member family?"

"A five-member family includes the sand rat or the drill head rat."

Huh?

Zhou Yi wondered if he had heard wrong: "Did you say sand rat and drill head rat?"

"Yes."

The Bone Man Minister scratched his already shiny brow bone with his finger: "The situation is this. Due to lunar ecological transformation, Lady Night God personally handled the gemstone transformers as support, the atmosphere has initially taken shape and is further stabilizing. Against this grand backdrop, some Earth organisms are being transplanted and moved to the Moon to supplement the overly barren ecology here."

"Among the mammals, the sand rat and its cousin, the drill head rat, are the first species introduced. They survive very well, with low demands for living conditions – just water, a little air, food, even lacking light won't affect them. In lunar biological cultivation experiments, sand rats have always been the most important and commonly used experimental animals."

"They enter the Bone Fish's body. Inside, there's a dedicated space equipped with a portable life-support system, producing oxygen, water, and some food reserves. They can move around inside and have emergency sleep cabins. Once in the safe zone, they can exit to explore externally."

Zhou Yi was puzzled: "Why?"

The previous ones could be considered strong alliances.

Despite the sand rat and drill head rat's strong survival abilities, they seem inadequate compared to the Bone Fish, which can physically travel through space.

"They have one irreplaceable special advantage."

Jacob spoke solemnly: "Chairman, they consume mantle bacteria. This is so far confirmed, the first animals able to digest and continuously feed on mantle bacteria."

"..."

Zhou Yi was initially stunned.

Then he quickly realized, "So, the sand rat can adjust the mantel bacteria distribution inside the Bone Fish? And clean it accordingly, tailoring to the Bone Fish's needs..."

"Yes, Chairman!"

Discussing this point, the Bone Man Minister emitted a strange laugh: "This seemingly simple characteristic is greatly significant in utilizing mantle bacteria."

"The sand rats have become cleaners and tailors inside the Bone Fish. If the Bone Fish finds too many mantle bacteria accumulating too densely, they can rely on sand rats to reduce the quantity and thickness, and even clean up locally dead and deposited mutated mantel bacteria."

"In the past, this was an extremely tedious and difficult task. Once the mantel bacteria adhered to the bone surface, they would interpenetrate at the atomic level, making them almost impossible to fully clean."

"Thus, these layers grew increasingly numerous. For the Bone Fish, this not only felt uncomfortable but caused their bodies to become dulled, reducing flexibility. Physical changes also affect their consciousness, making them increasingly numb and indifferent because bone physical perception continues to weaken, eventually fully turning towards energy sensing."

"We suspect the cold nature of Giant Bone Fish is due to this physiological trait's impacts."

"But with the sand rat and drill head rat, Bone Fish remain Bone Fish; their personality stays lively and active instead of deathly silent and numb. They all love the sand rat groups. Hence, the sand rat's importance is arguably second only to mantle bacteria, forming a sort of accompanying ecological balance group."

Zhou Yi felt a sense of wonder internally.

Sand rats played a significant role in the domain of mantle bacteria; life is indeed astonishing, as you never know when they might showcase their skills.

"What about a six-member family?"

"Six-member typically refers to the Cave People joining."

Zhou Yi was shocked.

How did the Cave People join a bone-based family?
