The Flash's speed in the comics is practically limitless. He can travel through time and even across different dimensions with his amazing velocity. But it's all part of the creative storytelling and can change to keep things exciting.
Mange progression can be quite unpredictable. Sometimes it spreads quickly if not addressed promptly, but in other cases, it might progress more slowly. It also depends on the severity of the initial infestation and the animal's immune system.
In StarCraft, Leviathan was able to achieve interstellar travel by controlling the interstellar spaceship under its control. Interstellar spaceships could travel freely in interstellar space through wormholes and stargates to reach other planets or galaxies.
Leviathan explored the unknown interstellar space through the interstellar spaceships it controlled, discovering new planets and galaxies, collecting resources, developing technology, and contributing to the progress of Leviathan's civilization. At the same time, Leviathan was also facing various dangers and challenges in interstellar space, such as black holes and high-energy particles. It needed to maintain a high degree of vigilance and ability to cope.
Well, it could be related to some sort of power - up or inheritance in the fanfiction world. Maybe Naruto discovers a hidden bloodline trait that not only gives him new abilities but also enhances his learning capacity. So he can quickly grasp new jutsus and combat strategies.
The speed at which mange spreads to humans depends on various factors. If there's direct skin-to-skin contact with an infected pet or wild animal, the risk is higher and the spread can occur quite fast. However, if precautions are taken and contact is limited, the chances of transmission are reduced.
It depends on the specific manga. Sometimes the story progresses quickly, but in other cases, it might take its time to build up the plot and characters.
