Comet zoomed in at a speed visible to the naked eye, and then swept past the cell cluster at a high speed nearly ten kilometers away.

　　 When Huogu reacted, the distance between the comet and the planet with a diameter of several tens of kilometers was only 300 kilometers.

　　 At the high speed of the comet at this time, if nothing happens, it will hit the surface of the planet at an external angle under the gravitational pull of the planet in a few minutes at most.

　　 So far, everything that happened was normal. Although the appearance of the comet was a little unexpected, it was because Huogu was focusing on searching for the unknown enemy, and he subconsciously ignored the result.

　　 However, the world started to be abnormal in the next second.

　　 A source of strong gravitation appeared inexplicably, and what appeared was so abrupt and without warning.

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

This gravitational point is invisible, but can be felt. Through the force deformation of the cells in the titanium alloy carapace and the comparison data of the planet, Hogu can roughly obtain some information about the source of gravitation-the source of gravitation and the planet, the gravitational strength is equal, the space The location is different.

　　 Observing from the perspective of a bystander, it is as if the center of gravity inside the planet suddenly jumped out of the inside of the planet.

This phenomenon of gravitational point transfer lasts only a few seconds, but this is enough. The comet that should have impacted at an external angle is dangerously and dangerously from the troposphere and stratosphere from the surface of the planet. The separation zone passed over a distance of about twenty kilometers.

During this passing process, the comet was decomposed. The comet with an average density of only 100kg/m^3 has exceeded the rigid Roche limit between it and the planet, and it shattered into five pieces with a diameter of 10 kilometers. Comet fragments between five kilometers.

　　 However, since its own speed is far greater than the gravitational escape speed of the planet where Huogu is currently located, even if the comet disintegrates, the fragments did not fall to the surface, but passed by the planet and parted ways.

　　 It took a long time for Huo Gu to wake up like a dream, not knowing what words to use to describe the situation it is currently seeing.

　　 The line of sight moved back and forth in the position where the planet and the source of gravity had appeared, and some kind of shocking thought came into being.

　　 "That thing shouldn't be..."

　　 "Not good! The height is falling!"

　　 Due to the gravitational disturbance that just appeared, the cell cluster broke away from its original orbit and fell towards the planet.

　　 At this time, the matter of the source of gravity was temporarily put aside, Huogu needs to deal with the matter at hand first.

　　 The command was issued, and the cell cluster in the appearance of the cone turned the body, the sharp head was facing the starry sky, the tail was facing the surface of the planet, and the balance wings on both sides of the shell stretched out.

　　Since the enemy is not in space, Huogu has no need to pay attention to space for the time being, but before that, Huogu needs to recover the cell clusters that were launched into outer space.

　　 Huo Gu did not intend to abandon this cell cluster, which is inconsistent with its principle of action, even if the opponent is just a biological tool.

　　 The falling speed is getting faster and faster, the air rubs against the titanium alloy shell, and the elongated flame column wraps the cell clusters. It is the same as the scene when it was launched into space, except this time, it returned to the surface.

　　 When the cell cluster is more than 30 kilometers away from the surface, the advancing ignition jet at the tail of the cell cluster suddenly slows down a lot.

　　 Then, an airbag from the top of the cone is deployed, and the other end of the airbag is connected with liquid hydrogen as fuel. Under normal atmosphere, the liquid hydrogen is quickly converted into hydrogen, and the airbag is filled to the limit.

　　 The rate of descent has been further slowed down. With the strength of the titanium alloy shell, the speed at this time can no longer cause any danger to the cell clusters, and Huogu can also shift his mind to other things.

　　 Hostile cyclones, lava, and lightning are still raging on the planet, destroying the rhizome system.

　　 It is unknown that there is an attack on the rhizome system for a long time, even if there is no Huogu to hinder the interference.

　　Because the original plan was long-planned, the layout area is extremely large, the organic material reserves are in units of '100 million', and various attacks are preconceived and targeted defenses are made.

　　 Huo Gu didn't react immediately, it was just observing that Huo Gu had a general idea about the enemy's true face and combining all the previous information.

　　 However, this idea is so unbelievable that even the proponent of it can hardly be convinced.

　　Moreover, there are some parts of this conjecture that are difficult to explain, such as the enemy's hostility to rhizome systems and octahedrons.

　　 Just when Huogu made a new test plan to confirm his guess, a certain abnormal situation on the planet caught Huogu's attention.

　　 First of all, the rain stopped, and the dense cumulonimbus cloud disappeared once~lightnovelpub.net~ From then on, the day of this planet is no longer chaotic and without any reference, but divided into day and night.

　　 In the daytime, you can see the stars rising slowly, the leading big brother in this planetary system.

　　 In the dark night, without the slightest light pollution, the sky full of stars will make the night no longer so dead.

　　 The source of all this is from the battle between Huogu and the unknown enemy, and the five comets that have escaped and were dismembered by the tidal force because of Roche's limit.

　　 In order to maintain a huge body, the octahedron relies on muscle cells all the time and consumes a huge amount of methane in the atmosphere. This leads to a sudden decrease in the concentration of methane in the atmosphere and a surge in carbon dioxide content.

Although the comet passed by, its own low temperature still caused the same effect as the'fuse'. Under the action of the'fuse', the'cause' transitioned to the'fruit', just like the collapse of a domino. Once it starts, it will be out of control.

Of course, these are not the key points. The key point is the changes that are taking place on the planet. They are unusually fast, just like the fast-forward button of a video tape. Day and night are like light switches played by bears and children. Dimmed.

　　 For a long time, Huo Gu threw away those who understood what was happening now—its perception of time was decelerating.

The temperature further dropped. In Huogu’s vision, the ice on the sea surface was like weeds, growing everywhere, and soon declared the hegemony of the sea and the land, and icebergs rose up on the ice, just like weeds. It's like being in a virtual game world.

　　The last sight Huogu saw was the extremely cold world wrapped in silver and covered in snow and ice.

　　 After this, it was the darkness coming from behind, as if falling into a bottomless black hole.
