In a world where there are clear distinctions between immortals and mortals, Yun Ming, a medical and engineering student, is unwilling to accept the iron law of "spiritual roots are determined by destiny". He buried his head in the laboratory, using micro-carved "black ants" (nano-robots) on his fingertips to clear his stagnant spiritual veins, using "spiritual needles" (CRISPR technology) to activate his dormant spiritual consciousness, and even using "star tubes" (carbon nanotubes) to reshape his spiritual energy pathways. Faced with the resource monopoly of immortals and confused mortals, he founded "Qiming Lu" and used "Lingling Jade" (3D bioprinting) to build the foundation of the rootless. From the microscopic world of lonely lights and shadows to the "vein-weaving standard" that shakes the millennium order, Yun Ming uses the sophisticated "Lingyuan Instrument" (metabolism simulator) and flowing wisdom to weave a ladder to heaven for all living beings.
