With Pinxixi in hand, I have a supermarket in the Changzheng!

After Zhou Yue entered, she found that several oil lamps were lit in the room. The dark room was illuminated by the flames, and everyone was busy.

Zhou Yue looked at these oil lamps in wonder. In those days, every household was basically in darkness at night.

Of course there was no electricity, so at night we could only use candles or oil lamps for lighting.

Candles and kerosene both cost money to buy, and ordinary families in the countryside could not afford to light lamps and burn oil.

So every time Zhou Yue passed through so many villages and towns, at night, the villagers' homes were pitch black, without any light at all.

I didn't expect that Jinxi is quite wealthy and would even be willing to light up the lights at night!

You don’t need to bother processing the seaweed you pick up, just spread a thick layer of sea salt on it and hang it on the rope.

Today's dinner was also simple. We cooked a big pot of fish and shrimp and shared it with everyone.

I also chopped the kelp and cooked a big pot of delicious kelp soup.

After finishing her meal and washing the dishes, Zhou Yue felt that it was time to go back to her residence.

After all, it is not possible to work at night because the lights need to be kept lit, which consumes too much lamp oil.

Unexpectedly, no one cared about spending the lamp oil at all, and they even lit two more lamps to make the house brighter.

"Chunyan, look! We caught a lot of oil mill owners today!"

Li Fusheng and Lin Hai each carried two large buckets into the kitchen.

In the light of the candle, Zhou Yue could see clearly what was in the bucket.

The four large barrels were full of fish, the likes of which she had never seen before.

Zhou Yue was very interested in the name of this fish. Why was it called Oil Fangzhu?

I was really curious, so I asked the system.

[Tongzi, what kind of fish are these called oil-bearing fish? ]

The system spent three seconds searching on Baidu and got the answer.

[Sister Yueyue, this is a feather-gill mackerel, a type of mackerel. It has another name called oil-barrel fish, and in some places it is called oil-barrel fish! ]

After knowing the species of the fish, Zhou Yue continued to ask.

[The name of the Oil Mill Master is strange. Is there any origin of this name? 】

[This fish has a very high fat content, and the fish oil is very suitable for making fish oil lamps, so some people call them oil masters! ]

Zhou Yue was really surprised to hear this answer.

It seems that she has too little knowledge. She doesn't even know that fish can be used to make oil lamps!

[Fish oil lamp? Can fish be used as oil lamp?! ]

Sensing Zhou Yue's surprise, the system spoke to her in a slightly arrogant voice.

[Yes! There are records of fish oil lamps in ancient times! In ancient times, there was a history of using fish oil to make lamps, especially whale oil lamps, which burned very fast. One cubic meter of whale oil could last for thirteen years! According to legend, there was also mermaid oil, which could be used to make a thousand-year-old everlasting lamp...]

The system kept explaining science to Zhou Yue, and the more Zhou Yue listened, the more excited she became. It was really amazing!

"Sister Chunyan, are you going to use these fish to make oil lamps?"

Wang Chunyan, who was cutting fish, smiled and nodded in agreement when she heard this.

"Yes, Xiaoyue is really smart. Can you help me?"

Zhou Yue couldn't miss such an interesting thing, so she agreed excitedly.

"okay!"

The fish in the four large barrels weighed an estimated 100 kilograms in total.

The meat to be used is from the body, so the head and tail must be cut off first.

Use a kitchen knife to cut the fish meat from the body into chunks and set aside.

While cutting the fish, Zhou Yue discovered that this kind of fish was really fat.

Hands that have touched fish can feel greasy. The fat content is really high.

Zhou Yue was already beginning to feel curious. She wondered how much oil could be produced from the fish meat.
