In 2291 A.D., this is the era when human beings built large-scale solar power stations in the orbits of the earth's geostationary satellites, so that they could completely get rid of the interference of the earth's atmosphere and use solar energy as a clean energy source with high efficiency.

In this era less than 100 years before the destruction of the earth, the unmanned spacecraft that sailed from the earth to the outer reaches of the solar system to achieve the purpose of learning more about the universe inadvertently discovered a substance that was completely unknown in the history of mankind - conversion matter in the process of flying over Pluto and continuing to explore outward.

When the transformation of matter was first discovered, although it was completely different from all the substances on the earth in the way of interatomic bonding, so that the crystal structure, chemical bonds, these chemical concepts that had been fixed for a long time, have been developed and extended in a breakthrough, but before scientists found what kind of exact function it can provide for the development of human beings, as a new substance, it did not receive widespread attention from the society, until the discovery of the "tide".

Anyone with a little knowledge of physics knows that not all matter in this world can be seen and touched like those made up of molecules, atoms, or ions. Invisible and intangible substances, such as magnetic fields, electric fields, and electromagnetic waves in the non-visible light band, do exist. And tide is just such a substance.

Just as a small magnetic needle is deflected in a magnetic field and an electric charge placed in an electric field is subjected to a force, visible matter has helped humans understand and recognize invisible matter, and the conversion matter that has been brought back to Earth from space outside Pluto is precisely the kind of matter that has allowed mankind to discover the matter that has in fact been in the same time and space as us and has always surrounded us like electromagnetic waves.

The invisible and intangible tide continuously emits electricity through the interaction with visible and tangible transformed matter, just like a solar power plant illuminated by sunlight.

Based on this characteristic between the tide and the converted matter, a large number of generators were built, and then countless tidal power stations were built, and the human beings were completely freed from the dependence on traditional energy sources such as coal and oil, and were able to embark on the road of clean development.

As a product of the Big Bang, it is an inexhaustible tide that exists in the universe as widely as electromagnetic waves, and was originally the most perfect energy source for human beings.

It does not have any negative impact on the entire ecological environment of the earth, and it will not be disturbed by the atmosphere like solar energy, nor does it need to ask the outside world for the power to cut magnetic inductance lines like hydroelectric power, and at the same time, it will not be like a nuclear power plant, there will be pollution once a nuclear leak occurs, and the tide of problems such as nuclear waste is difficult to dispose of.

For all mankind, such a clean energy can indeed afford the praise of the word "the most perfect". It's just that the adventitious insects who visit the earth have made human beings understand that perfect things are absolutely impossible to exist in this world.

The adventitious insects that originally lived in outer space, which was very far away from the solar system, and roamed around the universe to collect and convert materials to bring back to their nests, are alien creatures that rely entirely on electricity and live on electricity.

Adventitious insects that have never visited the central region of the solar system, including the Earth, have never visited the central region of the solar system, including the Earth, by bringing the converted matter back to the center of the nest and constructing a "feeding ground" for adults and a "nursery" for breeding larvae.

It was not until human beings artificially synthesized and put into use on the earth on a large scale in order to use new energy in accordance with the research results of the first discovered conversion matter, and like a great white shark that came to hunt after the smell of blood, it captured the special magnetic field generated by the interaction between the tide and the converted matter to discharge, and visited the adventitious insects in the solar system for the first time, and almost caused the extinction of all mankind.

When the indeterminate insects first visited the solar system, due to the tidal power stations all over the major cities on the earth, space stations, and spaceships, which are populated in large numbers, humans who knew nothing about this alien creature did not think that their real goal was actually to convert matter and not humans.

It wasn't until nearly sixty years after Hope's voyage that scientists aboard the Hope, who made bold assumptions and carefully verified them, were fully determined what the true goal of the indeterminate worm was.

Sailing on the voyage to the sixth planet of the Karen system, with all kinds of resources in short supply, but having to feed so many people, even if they know that the use of converted matter to generate electricity will attract adventitious insects, and it is impossible to sustain without electricity, they must take such a huge risk to continue to operate the tide station.

In order to be able to move freely in a vacuum, spaceships and humanoid mechs that cannot obtain reaction force from the ground like walking, and cannot fly into space by consuming a large amount of traditional energy like a rocket, and their power propulsion devices are therefore helplessly used to convert substances and chemical compounds, so as to obtain forward momentum through mutual reaction with the tide.

At the time when the adventitious insects visited the solar system, because almost everyone was carrying electronic devices, they wreaked havoc on the tide station and scavenged the adventitious insects that converted the matter, and then extended their tentacles to the humans who carried the food - electricity - on their bodies.

According to scientists' research, adventitious insects, which can convert water and inorganic matter ingested into the body into organic matter through electrical energy, just like plants photosynthesize, were initially not interested in creatures like humans.

It's just that in the process of devouring electronic products, the human beings who are devoured by adventitious insects do not need to go through self-synthesis to obtain a large amount of various organic matter, so the adventitious insects that have tasted the sweetness in this process have since changed from producers like green algae to producers and consumers like Nepenthes.

More than 500 years of interstellar cruising have made "adventitious insects that are willing to devour humans in order to quickly obtain nutrients" become the main body of the entire adventitious insect species, so today's controllers cannot get a chance to survive by abandoning the mecha with the conversion substance and then ejecting the control cabin like their predecessors hundreds of years ago.
