In a hidden workshop, inventor Leo crafted a material that stored and released sound waves. He wrapped it around a tree, and whispers from centuries past whispered back. Echoflex revealed secrets, connected eras, and gave voice to the voiceless, reshaping the boundaries of history and memory. This was nothing short of a revolution. He knew that he could use those sound waves in knowing more about the history of mankind. This material helped him in getting closer to nature. This is why he labeled it nature. He wrote a book named after this material.
