Station of Time and Space: In the realm of time and space, there are hundreds of millions or even more small worlds, and some worlds are overlaid with several parallel planes. When these planes overlap in a certain period of time, or the small worlds are affected by external influences, bugs will appear. BUG means that the original time track is destroyed, and rebirth and time travel are two of them... This will cause chaos in the plane, collapse of the plane, and even cause a black hole in time and space.
In order to eliminate these hidden dangers, the Time and Space Station appeared. This was created unconsciously by the Time and Space Boundary in order to protect itself from destruction. It will look for suitable souls and put them into the planes where bugs occur to repair the damaged planes.
It is equivalent to each plane being a host. If a virus appears and the host's firewall is destroyed, it will ask for the help of anti-virus software, and they, the space-time repairers, are this anti-virus software.
