Echoes of Fire: Humankind's Last Evolution

Humanity split into three branches after the "Silent Cataclysm": Mecha Expeditionary Force: Control the "Prism Mecha" to salvage lost civilizations in the quasar passage. Gene Builder: Unlock "Sequence Omega" and try to make humans jump out of the biological ceiling. The lightkeeper of time and space: carrying the "precession lighthouse" on his back, looking back at key historical nodes and preserving the fire of civilization. The protagonist Lin Que was originally a third-level maintainer, but unexpectedly resonated with the "Zeroth Fire", the core relic of the three major systems. It can project choices between "past-present-possible future", but each choice must be repaid with an equal price in reality. In order to prevent the true source of the Silent Catastrophe - a "history" that has been artificially deleted, Lin Que must make a choice between the mecha battlefield, genetic evolution experiments, and time and space calibration that will rewrite the direction of mankind: Is it to make human beings "stronger" or to let human beings "continue to be human beings"?
