About 700 kilometers from a small underground cavity, the rhizome that had been trying to move forward stopped growing, and over time the root tip swelled to form a sphere.

Inside the sphere is a hollow structure, and one of them, a fist-sized lump, like an organ-like object, is constantly pulsing.

After a while, the object that appeared to be an organ was still beating, but it was not as energetic as it was at the beginning, both the amplitude and the speed of the expansion and contraction had decreased a lot, and there were six more protrusions on the wriggling flesh wall that pointed in different directions and were equidistant from each other.

It wasn't long before the organs cracked with the object inside, and an octahedral shape was exposed to the cavity of the ground held up by the rhizome sphere.

This regular octahedron is as clear as glass, and you can see the various pipes crisscrossing its inside, with fifteen edges, in addition to the twelve exposed, and three diagonal lines perpendicular to each other inside.

The slightly agitated surface suggests that this creature is a creature, a creature that blends three-dimensional geometry and life in such a perfect way that it is not abrupt, but full of a different kind of beauty.

The rhizome continues to play its role as usual, with a large flow of material from afar through a biological pump composed of muscle cells.

These streams of matter are quickly absorbed by the octahedron, and their presence and the biological pump in the body quickly divide these substances to all parts of the body, and the body is enlarged in equal proportions without changing its shape, and the transparent color of the surface gradually fades, replacing it with dark black metal scale armor.

Soon, the hollow structure of the rhizome could no longer accommodate the ever-growing octahedron, and the inner space of the rhizome ball was broken.

At the command from afar, the broken rhizome was quickly repaired, and countless roots stretched out and dug into the interior of the octahedron, continuing faithfully carrying out the task of transporting matter.

The octahedron began to show its power to the world, and the space in the stratum was constantly expanded, and the octahedron used its own muscle cells to fight against the pressure from the strata.

This confrontation has been completely poured out on the octahedral side.

Increasing size often means that strength plummets, and if the size is infinitely larger, even the strongest metal can become fragile.

However, in the face of increasing pressure on the strata, the octahedron remained unmoved, and always maintained its unhurried expansion of its form.

This is all thanks to its own structure, the internal skeleton is all connected to form a triangle, which provides an absolutely stable structure for the octahedron, and the design of the octahedron with hypotenuse allows the pressure exerted by the stratum to be dispersed and shared by the whole body.

It is unrealistic to rely solely on the skeleton, in which the octahedron plays the role of 'Hercules', and most of the pressure is shared by the huge number of muscle cells of the octahedral weight, which constantly consume methane to provide the prime mover for the overall structure of the octahedron, so as to achieve the purpose of weakening the external pressure.

Corresponding to the octahedron in the strata, the sea level of the planet is falling, as if an invisible planet-level giant beast is leaning down to drink, and the global water level has dropped between one and twenty meters.

The octahedron followed the instructions, tirelessly expanding its form, and soon, a new opponent appeared.

They are lava, the fire dragons of the Underworld, both disaster and wealth, even on Earth, they are the existence that humans absolutely do not want to provoke.

Now that the expanding octahedron has poked into their dragon's nest, how can they endure it?

Lava poured out at temperatures between 700 and 1,200 degrees Celsius, vowing to destroy the fools who dared to offend themselves.

The dark scale armor of the octahedron burned red from the heat of the lava, but soon the redness faded and returned to its original blackness.

Inside the octahedron, accelerated by the biological pump, the high-speed liquid water quickly carries away the heat, and the heat accelerates the rate of metabolism, and the volume of the octahedron increases even more dramatically - the lava becomes the one that is 'eaten' instead.

After the octahedral expansion continued for some time, the seabed began to rise, at first in a small and undetectable arc, and gradually became a small hill visible to the naked eye, at this time, only three kilometers from the ocean floor.

When the turbulent currents washed away the dirt and rubble covering it, the octahedron was finally completely exposed to the surface environment, and this process did not produce much movement, which was in stark contrast to the unstoppable momentum in the formation, as if it had retreated to the mountains and forests.

The shape of the octahedron continued to expand, and the internal skeleton structure became more and more complex, with countless triangular stable structures maintaining the main strength of the locality, and the fifteen main bones that grew out of the earliest period became more and more coarse.

After contact with the ocean, the octahedron expands further and the water level of the ocean decreases at the same time.

The rhizomes that have been lurking in the ground have emerged from the bottom of the sea, and they form a docking with the octahedron, increasing the intensity of the transport of organic materials and other materials.

The octahedron soon touched the surface of the sea, expanding almost at a rate visible to the naked eye.

…… One meter ...... 10 meters ...... 100m ...... Kilometer......

The top of the octahedron rises higher and higher above the water, and a nearby volcanic island is slowly disintegrating in this bottom-up process, like a bulldozer pushing the sand apart with absolutely irresistible force.

All this happened, Huo Gudu saw through the rhizome system, and couldn't help but feel a little complacency.

"If it weren't for the actual sample of the giant underground cavity support column, I wouldn't have been able to design a bone structure with such strength based on what I knew......"

Of course, it is not enough to just rely on the support columns, and with the help of those alien skeleton fossils that were discovered later, otherwise Huo Gu really would not have been able to design such a self-consistent and integrated iron skeleton in such a short period of time.

Bones are not like alloys, just throw them in the furnace and burn them, and then knock and beat, and it's over, on the microscopic scale, the bones have a more microscopic structure, and it is precisely because of this that the bones will become wider and larger with the growth of life.

From the bottom up, Hogu's perspective swept over the octahedron that swelled out of the sea, and then from the top of the octahedron, his gaze shifted to the orange-red sky with dense clouds.

"It seems that it won't be long before we can make an understanding of these troubles now......"

Shortly thereafter, just as the octahedral height had risen to an average height of about five thousand meters above the surface, the tornado column that Huo Gu was familiar with and hated to his teeth appeared.
