Think About Making Yogurt

"Although it sounds a bit unacceptable, this is actually the only way," Lu Zhe's words this time obtained general approval from everyone.

There was no need to talk about nitrate ore, that stuff was hard to come by. Without a big pot, using the only thing that could be used to fry food - the steel helmet - to boil feces was a bit inhuman.

Moreover, even if it was used, turning the camp into hell might not necessarily collect much.

The containers were too small to qualify to boil feces!

"So how exactly should we do it, build a dry toilet?"

Lu Zhe nodded: "Although flush toilets are good, currently everyone can only endure a bit for the nitrate."

The few girls had difficult expressions on their faces.

"What's wrong? Weren't we like this before? Think about the swing latrine?"

Lin Qianqian's face turned red. "It's not the same! Every time we would bury it afterwards!"

Tang Xiaoguo shrugged. "Yeah, we're all fairies, how could fairies let others see that kind of thing?"

Jiang Yao sighed: "Fruit, think about the strawberry seeds!"

"Don't mention that dark history!"

Ning Shu asked somewhat tangledly: "Lu Zhe, do we really have to leave it open without burying it?"

"It's not leaving it open, it needs to be placed in a shaded area, and can't be poured on by rain! After leaving it for a period of time the nitrate salt can be collected."

Shen Bing supplemented: "Ours plus the cows', after two weeks, we can have some reserves of nitrate salt."

Lu Zhe nodded: "Tomorrow I'll dig a pit near the camp, then build a brick wall around it, it can be used as a simple dry toilet. Everyone should go to that place to use the toilet these days!"

The girls looked at each other, each with exceptionally complex expressions.

"Alright everyone, sleep earlier, there's still important work waiting for us tomorrow."

"Mm, good night!"

"Good night!"

"Lu Zhe, aren't you going to wash up?"

"Mm, I'll just wipe myself down."

"Can you reach your back?"

"..."

Another day passed, the camp lost a few beautiful flowers, gained a box of nitrate salt that could be used for refrigeration, and the roof also changed from palm leaves into crocodile skin.

It lost some sweetness, and gained some fierceness.

August 13th, the 65th day stranded on the deserted island, Saturday!

Waking up early in the morning, finally no one was annoying.

The weather was still humid, but everyone's condition was clearly much better.

There was a lot of work, the tasks were complex and heavy.

After eating a little, Lu Zhe hurriedly entered work mode.

He first fixed up the kiln with Shen Bing, and put in the bricks that were dried overnight last night, lighting a fire to conduct high temperature calcination.

During the firing process, he and Ning Shu found a place in the woods near the camp.

It was under a rock. There were also tree branches above, a good place to build a dry toilet.

Lu Zhe dug a pit underneath, then used big and small rocks to build it up inside.

On top he tied the swing latrine.

A simple dry toilet was completed.

When nitrate ore was found, or when the reserves of nitrate were almost used up, it could be buried, and a clean and sanitary flowing water latrine could be used instead!

With the latrine done, the first batch of bricks had just finished firing when he returned.

During this time, Lu Zhe started measuring under the banyan tree. Then he built up the earth to make the uneven ground with roots flat, as the foundation.

After the second batch of bricks were fired, he built them into a 2 by 2 meters by 40 centimeters tall square brick frame.

Then outside these brick frames he piled a lot of sand, and finally poured water into the sand.

As the water evaporated, it would take away some of the temperature from the bricks, and the bricks would take away the heat inside, thus achieving a cooling effect.

Laying grass mats and bear fur inside to increase comfort, using palm leaves above as a cover to prevent cool air from escaping, the principle was exactly the same as a soil refrigerator.
