The progress of Infinity was smoother than Lin Xian expected. Apart from encountering the Hunting Body on the first night, they only faced harassment from some scarlet zombies or energy-devouring worms during their journey. Although the Infinite Train had more than a dozen carriages, it relied on heavy defenses and a large deployment of drones, so these monsters posed little pressure.
Yet, the smoother it seemed, the stranger Lin Xian felt. As they delved deeper into the scarlet, Infinity was now traveling across the mountainous plains east of the Sierra Madre Mountains in Mexico. The tracks were not particularly smooth; this north-south mainline was nearly 40 years old and not part of the Star Orbital main route. After the apocalypse, tracks without maintenance faced frequent situations like breaks, rust, and terrain collapse.
