I can't remember exactly what day it happened 20 years ago, but people living on the equator in the southern hemisphere of the earth never sent the sun away after the morning sun was blazing. For a long time before that, every few minutes before nightfall, the glow of the sun, like a gold-edged dark red wave, surged to the horizon, and there were always wisps or two of them, the color of which was like the flush of the cheeks of a feeble fever-stricken patient, and though not unsightly, it was a sign of death.

From that time onwards, the sunsets became vain, brutally driving away the occasional rain clouds, and becoming more and more fond of dominating the western skies in droves, wantonly diluting the intensity of the night in order to lengthen the day endlessly. Until one day, they succeeded, and the night in the southern hemisphere degenerated into the memory of yesterday, and if the heavy dark curtains were not tightened, people would lose that memory and forget what it was like to be in the dark.

The sun suddenly exerted its power on the earth, arbitrarily compressing the seasons into a single summer, and the earth was about to be destroyed beyond recognition by the patron saint who had transmitted light and heat to it for nearly five billion years.

After months of rain, the Burning Inferno opened its doors to the southern hemisphere, its furnaces exposed on the ground, and the rising temperatures kicked off the Age of Earth's Cataclysm.

The first to be fatally affected was the Antarctic Polar, where penguins and seals died in large numbers as glacier temperatures rose from minus 60 degrees Celsius, and East Antarctica, which is between 30 and 170 degrees west longitude, was the first to show signs of ice melting. The ice sheet, separated from the ancient Gondwana supercontinent, has been hiding for 100 million years under a huge ice sheet with an average thickness of more than 2.5 kilometers, and at this time it has to face the desperate situation that the ice sheet will break apart and the entire ice sheet will collapse.

The Wilkes and Queen Maude Lands are shrinking rapidly, the ice at the Wilkins Rim in the southwestern Antarctic Peninsula is melting, and the amount of floating ice floes in the Indian Ocean is exploding, and the freshwater ice breaks through the highly salinized sea ice and blends with it to raise the level of the Indian Ocean and diverge into the Pacific and Atlantic Oceans under the cutting of the southwest monsoon......

Ten years after the ice melt, the total area of 13.9 million square kilometers, equivalent to two Australia-sized Antarctica, only half of the Antarctic Peninsula and Ellsworth Land remained, and the entire South Antarctic and East Antarctica, including Bird Land, have completely disappeared from the earth's territory. At that time, some scientists predicted that the surviving Antarctic Peninsula would not melt for more than a decade, because if the temperature continued to rise, it would soon break through the zero limit and become positive, by which time more than half of the Earth's land would cease to exist.

The sea level of this beautiful planet, which is completely ruled by azure waters from an artificial satellite, has risen by nearly 40 meters in less than 20 years, and Oceania is the first of the seven continents to sink to the bottom of the sea, and then the disaster has spread to Southeast Asia, Indonesia, Malaysia, Singapore, Maldives...... These coastal countries with beautiful scenery and many tourists have all been reduced to the vast ocean.

The influx of foreign seawater, as well as the thermal expansion of the upper layers of the ocean when exposed to high temperatures, caused the sea level of the Atlantic Ocean to rise, and Miami in the United States swooped down like a drowning eagle into the sea, and from Tampa to Atlanta, and even a third of the state of Mississippi, people were frantically packing up and running north. The influx of American refugees, including Americans, into Canada has overcrowded this sparsely populated and elegant country known for its year-round coolness, and it is difficult to enjoy the red maple sky in the autumn.

The story goes back twenty-five years, in 2174 of the 22nd century. The first to notice this strange celestial phenomenon were the citizens of Sucre, a white city in western Bolivia.

Two meteorology students who finished the afternoon course climbed to San Francisco with a solar altimeter with a compass on their backs. The towering white bell tower of the University of Hapière was intended to accurately calculate the duration of the spring nights here by measuring the altitude angle of the sun at dusk. This is a research topic assigned by the professor, and they must end the experiment today and work out the conclusions. They love this type of assignment because it allows them to climb the clock tower through security checks and enjoy the sunset from the highest point in the school.

Shockingly, however, they found that the pre-set point of the sun's rays showed no signs of migration through observations every fifteen minutes. Three hours passed from 4 p.m. to 7 p.m., and the sunlight's beam shifted by only 78 millimeters, and if they had not used a measuring instrument, but had only observed it with the naked eye, they would not have been able to see that the sun was disappearing below the horizon according to the laws of nature.

With the meteorological knowledge they learned in class, the students realized that this phenomenon was extremely unusual. They discussed for a while whether the party in question was the sun or the earth, but to no avail.

There are only two possible causes of the anomalous celestial phenomenon: first, the Sun, a giant bright star with an apparent magnitude of -26.74, began to rotate with the Earth inexplicably, and the speed of rotation was comparable, so there was a spectacle of sunset on Earth. Second, the Sun is as quiet as ever, but the Earth has slowed down its rotation for unknown reasons, to the point of almost stagnancy, so it is always aimed at the Sun with the same face. The 78 mm Sun Angle Shift comes from the Earth's revolution around the Sun, which takes 365 days to complete a slow rotation and has not been affected by the change in the Earth's rotation speed for the time being.

The city of Sucre is located in the valley of the Cachimayo River at the eastern foot of the Eastern Cordillera Mountains, with a latitude and longitude of 65 degrees 16 minutes west and 19 degrees 02 minutes south latitude, and an altitude of 2,790 meters above sea level. Although the city has a subtropical climate, it has a mild climate with an average annual temperature of about 15.7 degrees Celsius because it is sandwiched between the Squeska Mountains and the Gunkra Mountains, which are surrounded by two natural barriers.

But in recent years, for some reason, the temperature has been rising year by year, and even in the cold of January, girls can still wear camisole shirts to show off their bodies on the street, which is really strange.

Ordinary citizens have limited knowledge of astronomy and geography, and they can't understand the reason, so at most they can only get together and complain about God, throwing all the blame on the El Niño phenomenon, global warming caused by air pollution, and so on.

But when it was discovered that the sun could no longer set, the extension of the summer changed substantially. Savvy people are gradually realizing that things may not be so simple, and that perhaps this is the prelude to some kind of natural disaster that is about to befall them.

In early spring, the sun, which was supposed to wave goodbye to the earth at about 6:30, still hangs in the western sky after 7 o'clock, like a strange lamp that unplugs its power and forces itself to continue to shine by devouring electrons free of air. If this phenomenon is allowed to develop, or even if it is only maintained, you can imagine what will happen next! If the temperature rises again and again, so high that it is impossible to see the nodes, the ecological environment will definitely be changed, such as the dry up and death of plants that can no longer carry out normal photosynthesis, the reduction of oxygen in the atmosphere, the extinction of many species due to the difficulty of animals adapting to the hot environment, and the crawling of aquatic organisms to the land after the water is cut off...... Biologists shudder to think about the fact that Darwin's biological chains will break and the surviving species will be reordered, and what the new order will be. In addition, the human world will gradually fall into chaos without night, and this threat from the natural world may lead to a new round of world war......

Two students called the National Meteorological Center of Bolivia and reported on the unusual changes in the sun, including not only the incredible fact that the sun did not set on time, but also the results they had measured with a measuring instrument.

Upon receiving the call, the Meteorological Center responded quickly and immediately reported the students' findings directly to the Global Consortium for Science and Technology, formerly known as UNESCO.

In fact, as early as 2125, that is, 50 years ago, five academic authorities on astrophysics from China, the United States, Russia, and South Africa jointly issued a circular to governments explaining at length that, according to reliable data analysis obtained from the monitoring system of the International Space Station, the consumption of hydrogen in the Sun's interior had accelerated for unknown reasons, and the increase in energy brought about by the intensification of hydrogen fusion had greatly increased the Sun's brightness, so that the volume of this massive star had expanded slightly. First of all, there was a negative impact on Mercury, which was closest to it. Despite this, the core of the sun is showing a tendency to collapse, and it seems to be suddenly old......

This bulletin is like a piercing alarm bell to break the calm of the 22nd century, the scientific and political and economic circles are boiling, countless astrophysicists have begun to study the solar system in depth, the government has also lowered the standard to provide them with funding for the first time, and all those in the know hope to find out as quickly as possible the culprit of the change in the sun and the impact of this change on the earth.

However, in order to maintain the stability of the global community and the hard-won peace, the heads of government unanimously decided to keep the crisis secret and not announce it to the public.
