He kept searching around and found some kelp that was frozen along the edge of the ice, with a white salt frost hanging on the surface. He also used the axe to chop them down and threw them into the bag together.
"These kelp are like natural condensed salt blocks. Boiling them together can greatly improve the efficiency of our salt production."
Lin Yu'an quickly transported the bag full of high-salinity seawater back to the camp.
He didn't boil it inside the shelter, as that would produce a large amount of steam, making the interior too humid.
Instead, he skillfully set up another fire near the shelter door, not using a simple campfire but building a wind-resistant "U"-shaped stove with an opening using a few stones.
This not only concentrated the firepower but also conserved firewood. Then he used three wooden sticks to create a stable rack, hanging the iron pot above.
