Against the roaring flood, groups of human beings struggled on the water surface, with bamboo lifebuoys tied around their waists. They were holding faintly glowing, heavy axes, madly hacking on the mountain in front of them. In the vast water, these human beings looked at tiny as ants.
Enormous spell symbols were carved onto the mountain, one after another.
From time to time, giant waves would strike down and press countless human beings under the water. They held their breath and waited until the waves fell, then rose again from the water, roaring like beasts. They raised their weapons and continued cutting and carving.
Sometimes, people would be rolled up by waves and bump heavily into the mountain, breaking their bones and heads. But other people would always silently take the places of these injured ones, pick up their faintly glowing weapons, and continue their work.
