Supreme Command, underground base, controlled nuclear fusion experiment site.
This was not humanity's first controlled nuclear fusion experiment, but it was the most hopeful for success.
It was not an exploratory experiment, but one that could be put into immediate use, skipping the majority of experimental steps—a first attempt at a practical controlled nuclear fusion device.
If successful, humans would gain the most efficient source of energy ever known, but if it failed...
If it failed, they would simply try again; controlled nuclear fusion was seen as humanity's future precisely because of its safety, cleanliness, and efficiency.
Furthermore, with the complete formulas and blueprints given by Xinghe, the consequences of failure wouldn't be too severe—at least it wouldn't blow the entire underground base to smithereens.
That was the significance of Xinghe; it not only saved humanity from taking detours but also offered the fastest shortcut.
