The end of science is mythology, and mythology is actually science too. You may not know this, but in ancient times, 800 million light-years from Earth, there was a place much like Earth. People called it the Celestial Court. Back then, four quantum time-space passages connected it to Huaxia, the largest of which was called the Southern Heavenly Gate. Later, a meteorite from beyond the heavens struck Earth, collapsing the passages. The dinosaurs, people's mounts, went extinct as a result.
Today, the technology of another world is advancing by leaps and bounds. Its crown prince is the first to open a space-time passage, arriving aboard a spaceship!!! What sparks will fly when this other world, still a feudal society, comes into contact with the modern world?
When AIDS is cured, when the creation of uranium-destroying substances makes nuclear weapons a thing of the past, when oil is no longer the main energy source, and when the two parallel worlds formally establish diplomatic relations, the global economy and world order will undergo a major reshuffle.
