Then, coming back, he dug a pit on either side of the foundation of the west wall, laying stones inside and surrounding it with small stones to form a firepit.
There should be firepits on both sides to better prevent attacks from wild beasts.
They love to ambush from behind; it's in their nature.
Next, he began digging the wall foundation trench. It didn't need to be very deep as the walls were built rather casually, so the foundation didn't need to be too solid. Without metal tools, digging a trench was heavy labor.
He longed for iron tools, but bronze tools would be good too. Metal tools were always better than stone tools.
All these inconveniences were part of the hardship. The more hardships he endured, the closer he got to a happy life, without needing to care about the specific form of suffering.
His pottery tool was very clumsy for digging. Still, it was somewhat useful, much more convenient than using stones or wood to dig.
