As the egg of apocalypse ripened, the gargantuan meteorite mountain began to emit large clusters of air currents in various colors that interweaved with each other and grew toward the sky helically. They swallowed one cloud after another and eventually formed a swirl of seven-colored smoke in the sky.
The residents of Iron Plateau called such a phenomenon an 'apocalypse cloud'.
The appearance of an apocalypse cloud suggested that the egg of apocalypse would break out in several days.
The egg of apocalypse that was about to mature was on the northwest side of the Furious Bears Tribe. When it was sunny during the day, one could see that a small apocalypse cloud in the northwest sky, surrounded by colorful radiance but with immeasurable darkness in the center, was staring at the ground like a weird, unblinking eye.
One month earlier, Furious Bears City had been seething with enthusiasm like a giant steel refining factory.
