The bottom of the trench foundation on the east side hadn't dried. He could either fill it with dry soil and tamp it down or wait for it to dry naturally.
Ma Lin chose to continue waiting.
He then went to dig the trench on the west side. It was also dug only thirty centimeters deep and seventy centimeters wide.
His tools were really too clumsy. If he had a shovel, he could dig hundreds of meters of such trench in a day.
As he dug, he got another foot punctured and bleeding profusely. He was extremely frustrated.
When digging, he had to use his foot to stomp on the pottery to make progress.
Its shape was like a horseshoe-shaped spoon.
Extremely clumsy.
It was way too exhausting to dig without using his foot.
The feeling of crouching to dig with pottery shards and wooden sticks was very uncomfortable, so he had to keep using this clumsy tool.
