In the neon-lit city of Arteria, a small red dragon named Eryth lived inside a glass tower. Every day, he carried oxygen and nutrition to the city's cells, traveling through tunnels called arteries. However, one evening, a dark trap caught him in a narrow alley. The trap was a web of electric wires that blocked his path. Eryth felt scared, but he remembered his duty to keep the city alive.
Suddenly, a gentle voice said, "Don't worry, I will help you." It was a tiny robot named Pulse, who had once been saved by Eryth. Pulse used his tools to cut the wires carefully. "You helped me when I was broken, so now I will help you," Pulse said. Eryth felt a warm glow in his chest. Therefore, he knew that kindness always returns.
