The comet rapidly magnified at a speed visible to the naked eye, and then swept by at high speed nearly ten kilometers from the cluster of cells.

When Hogu reacted, the distance between the comet, which was tens of kilometers in diameter, and the planet was only three hundred kilometers.

At this high speed, if nothing else, it will hit the surface of the planet at an incisive angle in a few minutes at most, pulled by the gravitational pull of the planet.

So far, this has been normal, although the comet's appearance was a little unexpected, but it was because Hogu was so focused on searching for the unknown enemy that he was distracted and subconsciously ignored the result.

However, the next second the world began to be abnormal.

A strong gravitational source appeared inexplicably, so abruptly and without warning.

At the same moment, the cluster of cells also slipped out of orbit as it lost its gravitational restraint from the planet.

This gravitational point is invisible, but it can be felt, and through the force deformation of the cells in the titanium alloy carapace, as well as the comparative data of the planet, Hogu can roughly obtain some information about the gravitational source - the gravitational source and the planet, the gravitational strength is equal, and the spatial position is different.

Viewed from the perspective of a bystander, it is as if the center of gravity of the planet suddenly jumps out of the interior of the planet.

This phenomenon of gravitational point shifting lasted only a few seconds, but it was enough, and the comet, which was supposed to hit at an inscribed angle, narrowly passed by the troposphere and stratosphere separation zone on the planet's surface, about 20 kilometers away.

In the process of this passing, the comet disintegrated, and the comet, with an average density of only 100 kg/m^3, exceeded the rigid Loch limit between it and the planet, and broke into five comet fragments with a diameter of between 10 and 5 kilometers.

However, because its velocity is much greater than the gravitational escape speed of the planet Hogu is currently on, even if the comet disintegrates, the fragments do not fall to the surface, but pass by the planet and go their separate ways.

After a long time, Huo Gu woke up like a dream, and he didn't know what words to use to describe what he was currently seeing.

The gaze moved back and forth to where the planet and the gravitational source had appeared, and a terrifying idea was born.

"Is that thing supposed to be ......?"

"Not good! The height is falling! ”

Due to the gravitational perturbation that occurred earlier, the cell cluster broke away from its original orbit and fell in the direction of the planet.

At this point, the matter of the gravitational source was put aside for the time being, and Hogu needed to deal with the matter at hand first.

The command was given, and the cone-shaped cluster of cells turned around, with the sharp head facing the starry sky and the tail facing the planet's surface, and the balance wings on either side of the shell stretched out.

Since the enemy is not in space, there is no need for Hogu to pay attention to space for the time being, but before that, Hogu needs to recover the cluster of cells that have been launched into outer space.

Hogu had no intention of abandoning this cluster of cells, which was inconsistent with its principles of action, even if it was only a bio-type tool.

The speed of the descent became faster and faster, the air rubbed against the titanium shell, and the long pillars of flame enveloped the cells in clusters, just as it had been launched into space, only this time, back to the surface.

When the cell cluster was still more than 30 kilometers away from the surface, the propulsion and ignition of the tail spurted the falling speed of the cell cluster and suddenly slowed down a lot.

Subsequently, an air bag at the top of the cone is deployed, and the other end of the air bag is connected to the liquid hydrogen as fuel, which is rapidly converted to hydrogen in a conventional atmosphere and filled to the limit.

The rate of descent was further slowed down, and with the strength of the titanium alloy shell, the speed at this time could no longer pose any danger to the cell cluster, and Hogu was able to turn his mind to other things.

Hostile whirlwinds, lava, and lightning are still wreaking havoc on the planet, destroying rhizome systems.

Unknown beings attacked the rhizome system for a considerable period of time, even without Hogu's obstruction.

Because the original plan was planned for a long time, the layout area was extremely large, with organic material reserves in units of '100 million', and various attacks were envisaged in advance, and targeted defense was made.

Huo Gu didn't react immediately, it was just observing, about the true face of the enemy, based on all the information before, Huo Gu already had a general idea.

It's just that this idea is so unbelievable that even its proposer is hardly convinced.

Moreover, there are some places where this conjecture is difficult to explain, such as the hostility of the enemy to the rhizome system and the octahedron as giant bio-type tools.

Just as Hogu was trying to make a new test plan to confirm his guess, an anomaly on the planet caught Hogu's attention.

First of all, the rain stopped, the dense cumulonimbus clouds dispersed, and from then on, the day of the planet was no longer chaotic, without any reference, but divided into day and night.

During the day, you can see the star rising slowly, the leading big brother of this planetary system.

In the dark night, there is not the slightest light pollution, and the starlight in the sky will make the night less deadly.

This heralds the end of the early rain period of the planet.

At the same time, the global temperature began to plummet as a result of the comet's passing over the planet's surface.

It all started with Hogu's battle with the unknown enemy, and the five pieces of comet that had escaped and been dismembered by the tidal forces because of Lohi's limits.

In order to maintain its huge body, octahedron always relies on muscle cells to consume a huge amount of methane in the atmosphere, which leads to a sharp decrease in the methane content of the planet's constant temperature in the atmospheric concentration, which is the fundamental reason for the cooling of the planet.

Although carbon dioxide is also a greenhouse gas, its properties make it soluble in water or converted into oxygen by oxygen-producing microorganisms, so carbon dioxide cannot fully play the role of 'heat preservation'.

Although the comet is only passing by, its own low temperature still causes the same effect as the 'fuse', the 'cause' under the action of the 'fuse', the transition to the 'fruit', like the collapse of a domino, once the balance changes slightly, it will soon expand and become out of control.

Of course, these are not the point, the point is that the changes that are taking place on the planet are unusually fast, like a videotape being fast-forwarded, day and night are like light switches played by bear children, flickering on and off at high frequencies.

It took a long time for Huo Gu to abandon those understandings of what was going on at the moment—its perception of time was slowing down.

The temperature dropped further, and in Hogu's field of vision, the ice on the surface of the sea was like weeds, 'growing' everywhere, and soon the supremacy of the sea and land was announced, and icebergs rose on the ice, almost as if in a virtual game world.

The last sight Huo Gu saw was the extremely cold world covered in snow and ice.

After that, there is darkness coming from behind, as if falling into some bottomless black hole.
