Chapter 1: Crossing

Crossing

Since records began, legends of 'otherworld visitors,' also known as 'transmigrators,' have never ceased among all planets and star fields.

Beings arriving from other worlds have never been limited to humans—giant beasts, plants, even mere objects, and so on and so forth.

But the most numerous appearances are of humans, and the greatest impact also comes from humans.

They may appear openly or hide their names; some dominate a region, others lurk among the crowd, but the alien knowledge and power they carry always leave traces, leaving stories.

Thus, later historians even suspect that many remarkable talents recorded in history were actually transmigrators.

In fact, there indeed are several kings and lords explicitly recorded as otherworld persons, as well as ancients whose transmigator identity was clarified through archaeology.

And today, research published by the Holy Terra Federation shows.

The core of the crossing phenomenon lies in world similarity—namely, using the solar system planet Earth (Terra) as the reference point, the homelands described by these otherworld visitors more or less point to Earth; regardless of how their star systems vary, their worlds always possess an ecological environment, and even a subdivision of nearby star systems, that is completely identical to Earth.

This seems able to explain the distribution of many crossing cases, from sparse to dense, all centering on Earth.

Furthermore, changes in Earth's environment also relate to fluctuations in the number of crossing cases.

Academia has thus derived countless hypothetical notions, including but not limited to—destroying Earth could stop all crossings, or destroying Earth would exacerbate more crossings...

The ideological conflict caused by this phenomenon is also one of academia's classic contradictions; the view that otherworld visitors can accelerate and enrich civilization's development, or that they would cause civilization to regress and suppress diversity, is likewise a classic debate topic.

Interestingly, the arguments of both sides in this debate are drawn from the development history of the Holy Terra Federation.

It is foreseeable that, as long as Earth exists and its Holy Terra Federation continues to develop steadily, the phenomenon of 'crossing' will persist.
