The hidden passage had led Rain to an unexpected discovery. It guided him down a staircase carved right into the earth, extending beneath his own house. As he descended, the tunnels stretched deep below the city's sewer system. However, there was an issue - a lingering, unpleasant smell hung in the air.
Quick-thinking as always, Rain put his earth magic to work. He strengthened the tunnel's ceiling, successfully neutralizing the odor. It was a testament to his growing mastery of magic, a skill he continued to refine.
As he explored further, Rain stumbled upon a fascinating sight: a rail constructed entirely from earth magic alongside a cart made from the same magical material. It was evident that these magical constructs were designed for transportation. An idea sparked in Rain's mind, fueled by his ambition and the desire to use his mana more efficiently.
