"Perfect! Now, one group keep cooking and stirring the cement paste. Another group, start pouring it into the trench. As soon as it's in, press the first row of stone bricks firmly on top. Then pour another layer of paste over the bricks and add the next row. We'll keep stacking until the walls are done!"
The tribe worked together like a well-oiled machine. Males carried stone bowls of the warm, thick paste and poured it carefully into the trench.
Others lifted the heavy stone bricks and pressed them down with solid thuds, making sure each one sat straight and tight. Paste went between every layer, sealing everything perfectly.
Layer by layer, the walls rose.
One row… two rows… three rows…
Everyone's eyes were wide with awe. "Look at that! The wall is already standing straight and tall!"
"It's so fast! And so strong!"
From a short distance away, the females and cubs of the tribe gathered, blinking curiously.
