If the oil has been stored for too long and the container is not dense enough, it is easy to develop a strange smell and is not good for health.

In the era of machine oil extraction, there are not many people who are willing to throw away the oil that has been fried, let alone this time and space when oil extraction relies on manpower and the output of edible oil is not high.

It's good not to mention this topic, but as soon as she mentioned it, she realized that she had eaten oil that had experienced two high temperatures for many years.

Just eat it, anyway, I didn't eat less in my previous life.

She picked up a piece of fried dim sum and said, "Oil is expensive, so you can't use it twice or three times." ”

Yao Nanxing nodded, and talked about the flowers that can be eaten like lotus flowers.

In the breeze and moonlight, after chatting for a while, the emperor and queen returned together. When he walked out of the Dingbei Hou Mansion, Zhao Zijing suddenly seemed to remember something, paused and asked Wan Wan: "During the Mandate of Heaven, Cheng Wenzhong wanted to improve the method of oil extraction, but he couldn't complete it. Does my brother-in-law know the unfinished method? ”

Zhao Zijing's idea is that since the weapons that were lost back then can be remade, then the rest of the equipment should also be possible, so there is this question.

Wan Wan is not interested in weapons and machinery, and the relevant information is also used to translate what. Only a few days ago, when I was sorting through those materials, I saw the documents about the oil press. She hadn't read the content carefully, and she didn't know if it was available.

For this kind of uncertainty, it is naturally useless to think, and it needs to be taken out and studied carefully to have an answer.

After sending the emperor away, and returning to Qi Ao Zhai, Wan Wan took the power bank that she had put out during the day in her hand. The place she chose to charge was high above the ridge of Tingfeng Xuan, and the surrounding area was open, and the sun was abundant during the day.

In the past few days, Feng Qingcheng has often seen Wan Wan connecting the ancient monster piece with the four gates, and at this moment, when she saw her take this thing from the top of Feng Xuan's spine, her face showed a puzzlement.

Wan Wan noticed Feng Qingcheng's expression, and said, "When I don't go out, I will be around there, and Aunt Tang is watching in the dark." ”

Security is still very guaranteed.

After saying that, Wan Wan suddenly thought that Feng Qingcheng should not be such a low-level question.

She thought for a moment and explained it with a phrase that the ancients could better understand, "Absorb the essence of the sun and the moon." ”

The small program designed by Wan Wan is very easy to use, and with a few fingers, she can find out the information about the oil press. This information is very comprehensive, from the evolution of Chinese and Western oil extraction methods to the principle and structure of various types of oil presses.

At present, the wood pressing method is used in this time and space, and the most advanced one recorded in the data is the intelligent machine pressing method of the assembly line test. Obviously, the most advanced kind cannot be achieved under the existing conditions, but there is still a lot of room to improve the existing oil extraction technology based on these data.

Firewood, rice, oil, salt, sauce, vinegar, tea, seven things for the people to open the door. On the issue of oil extraction, Zhao Zijing attaches great importance to it.

At the end of the two-day bath, the focus of Wanwan's work is the improvement of oil extraction technology.

The Northland side is still busy with war, and Xuanmen doesn't have the energy to figure out what oil press. There are still some Xuanmen craftsmen in Bianliang City, who were those who did not participate in that night's operation for various reasons. After the four gates were abolished, those craftsmen were divided into two departments: the general supervisor and the military and industrial departments.

Due to the problem of oil extraction technology, those generals were gathered and assigned to the yamen of Wanwan.

As the days passed, the new oil press also had eyebrows little by little.

The weather was at its hottest, but it was hotter than the rumors about Fengqing City. It is actually a bit inaccurate to say that it is a rumor, because everything in the rumors is true.

I couldn't find a reason, and Fengqing City suddenly became popular. The streets and alleys of Bianliang City are full of corners, gossiping about him everywhere.

This time, everyone is not saying how ridiculous he is a loser, nor how he is afraid of guilt, but how he helped Zhao Zijing through that period of ups and downs when Zhao Zijing first ascended the throne.

Rumors kept rolling in Bianliang City.

In one of the city's liquor stores. A Confucian shirt player pinched a wine cup and listened attentively to the gossip of several drinkers at the adjacent table.

Processing and interpreting those things into rumors, the truth hides the false, and the fake seems to be true, and if it rolls like this, it is enough to make Fengqing City's reputation even more famous.

With such ability and merit, under the fame, why can't you instigate Zhao Zijing's suspicion of Fengqing City; With such a scheming city, scheming skills, and the rumors that came out before, it is not worrying about instigating Ming Wanwan's suspicion of Fengqing City.

It's a two-pronged solution.

The Confucian shirt's good strategy did not make any splash with Zhao Zijing. Wan Wan gave a little reaction, but this reaction was not what the Confucian shirt thought.

Along with the rumors, Wan Wan has a new routine. As long as she didn't have anything to do, she would visit various teahouses and restaurants, streets and alleys, and listen to the energetic speeches of the people of Bianjing while eating snacks.

Her original intention was to make up for the lesson, to know what he had done and experienced during her absence. Hearing this, Wan Wan's eyes when she looked at Feng Qingcheng changed-in those already bright eyes, the light of the fan girl flashed more and more.

The efforts of the Confucian shirts were not completely ineffective. Wan Wan still had a little doubt in her heart.

In the middle of the night one day, Wan Wan suddenly sat up and poked Feng Qingcheng, "What those people said is not completely unreasonable, if Hengzhi wants to coax me, it seems easy to play."

Hengzhi's cleverness won't be used in the house? ”

In a deep sleep, Feng Qingcheng reached out and pulled her back into his arms, "How dare I." ”
