ECHO Final Source

Star calendar year 4037, the eve of the reconstruction of the order of galactic civilizations. Humanity has long been deprived of the right to evolve and has been reduced to a memory container set up by the "Image Parliament" of high-dimensional civilization. On the ruins of destiny, Lin Yao, a young man from the lower border, accidentally activated a fallen alien mecha. The mecha has no cockpit, but it can respond to consciousness; it has no code, but it can project memories. It has only one name - ECHO. He thought this was an unexpected miracle of survival. Unexpectedly, this was the start of a "civilization detonation experiment" spanning hundreds of millions of years. From stars falling into the wasteland to high-dimensional battlefields, from consciousness synchronization to personality loss of control, Lin Yao tore up the script of fate step by step, counterattacked enemy ships on the verge of death dozens of times, integrated alien technology, and reconstructed weapon systems. However, every memory he unlocks is not a roadmap for evolution. But... A return agreement of "rebirth of the old god". Civilization is dead, but the fire is not extinguished. He is not the savior, but the ultimate lead—— "You are not someone's continuation, you are the ultimate source of ECHO." When the last star burns out, his will will echo throughout the universe.
