The armor first activated invisibility, then silently took off, carrying Su Yu out of the Mechanical City without a sound, reaching a hundred meters high, and flew toward Illusion City in the southwest direction.
In just a moment, it had already flown over a hundred kilometers.
After all, it was twelve times the speed of sound, capable of crossing four kilometers every second.
The intense waves stirred up by the flight were counteracted by the armor's invisibility trait, only stirring up a slight breeze, almost without any sound.
Su Yu felt completely at ease now, with such strong invisibility abilities, he shouldn't be discovered.
Then, he threw caution to the wind and flew full speed towards Illusion City. Before long, he had flown another several hundred kilometers.
At such a high speed, the ground rapidly receded in Su Yu's eyes, and adrenaline rushed wildly.
