Cosmic Legacy: Earth's Rise from Ancient Technology

One desperate leap changes everything. When Qin Feng plunges into a waterfall, he's engulfed by an otherworldly beam—and awakens as humanity's last hope.

From failed nobody to Earth's potential savior, Qin Feng must master technologies millennia ahead of their time. But with cosmic power comes cosmic enemies, and the galaxy won't surrender its secrets easily.
