Time and Space Painter

The earth's environment completely collapsed, and humans were forced to move to alien planets' new homes. However, beneath the surface of this planet sleeps the war mecha 'Titan' left behind by an ancient super civilization. When humans were frantically digging for rare energy, they accidentally awakened these murderous mechas. Like hungry beasts, they tear human armies and cities to pieces. Retired mecha pilot Lin Luo discovered that these Titans can counter-control humans through neural connections. And his wife mysteriously disappeared during the first encounter, leaving only strange mecha graffiti at the scene—— That graffiti was exactly the same symbol that appeared repeatedly in Lin Luo's dreams!
