"With my current Movement Speed, if I enhance it further with Spiritual Energy, it can instantly soar to 52.4 Mach, almost comparable to twice the speed of an intercontinental ballistic missile. After all, the fastest intercontinental ballistic missiles in the world are only a mere 27 Mach. I'm just 1.6 Mach away from twice its speed."
Compared to intercontinental ballistic missiles, Zhang Yanhang's primary target is the space probe, such as the New Horizons. The launch speed of the New Horizons Space Probe is 48 Mach, which is slower by one Mach than the Voyager 1 equipped with the Golden Record that Zhang Yanhang had previously surpassed.
However, Zhang Yanhang mentioned the New Horizons because its peak speed far surpasses the Voyager 1's 49 Mach. When passing by Jupiter, due to Jupiter's immense gravitational pull, its maximum speed reached 62 Mach, which is over 21,000 meters per second, and its hourly speed reached as high as 76,000 kilometers.
