Who understands? He traveled through time with a high-spec spatial ability.

Dr. Feng smiled, his eyes crinkling. The aroma was enticing. He eagerly opened it to take a look; there was indeed quite a lot.

He picked out a little of each item on a small plate and placed it in front of him. He took out the wine Qiao Jingjing had given him and his own small wine cup, poured himself a small glass, ate a bite of fried chicken wing, and took a sip of wine.

Delicious! This is heavenly!

Seeing that he was enjoying his drink, Qiao Jingjing thought about how it was almost Chinese New Year and decided to let the old man experience double the joy. She took out a small handkerchief from her sleeve and wrapped some salted spiced peanuts that she had stocked up on at home inside.

"Hey, Dr. Feng, how can we drink without peanuts? They're the perfect accompaniment to drinking. Have a taste."

Dr. Feng believed it without question; he thought everything Qiao Jingjing brought out was delicious. Sure enough, after picking up a peanut and chewing it a couple of times, his eyes lit up instantly.

When Xuan Yi came in from outside, he immediately saw that Elder Feng was eating with great relish, with a satisfied smile on his lips.

His heart tightened, and he quickly walked over. Although Old Feng was never stingy when it came to money, he was a complete miser when it came to food.

To put it simply, if Old Feng had a hundred taels of silver in his pocket, and someone asked him to borrow ninety taels, he would lend it all to them without hesitation, and might even feel embarrassed that he hadn't been of much help.

But if someone shares the same delicious dish with him, the situation is completely different.

Old Feng wished he could keep the whole dish for himself, afraid that no one else would take a single bite. But he was also very picky about food and wouldn't enjoy ordinary dishes with such relish.

So when Xuan Yi saw Elder Feng enjoying the food so intently, he was naturally extremely anxious. After all, who wouldn't want to taste such a rare delicacy?

Tantai Zhou rested for a while, and when he woke up, he smelled the aroma of food. He got up and saw Elder Feng and Xuan Yi fighting over a chicken wing. "What are you doing?"

The two men immediately realized something was wrong; they had forgotten to leave a few pieces for their master.

Before Qiao Jingjing left, she explained, "Tomorrow is Chinese New Year, so I fried some snacks in advance. I brought them over for you to try."

Tantai Zhou's attention wasn't on the two subordinates fighting over something; instead, he picked up a piece of "Step-by-Step Cake," examined it closely, and then brought it close to his nose to smell it.

He asked bluntly, "This wasn't fried in lard. Could you tell me what kind of oil it was?"

"You have a really good nose. It's peanut oil."

Dr. Feng looked up, his not-so-bright eyes revealing great doubt.

"Peanuts? Peanuts can be pressed for oil? Is this the kind of peanut?" He asked in a series of three questions while holding the peanuts Qiao Jingjing had given him.

Tantai Zhou also looked at Qiao Jingjing, waiting for her answer.

"Yes, it's this peanut. But it's prepared differently from the peanuts you eat now."

The three of them immediately became interested. Xuan Yi simply brought over three small stools and sat in a row facing Qiao Jingjing. Feng Lao and Xuan Yi did not dare to sit at the same level as their master, so they sat slightly behind by half a step.

Qiao Jingjing felt something was strange, but before she could think about it further, Xuan Yi interrupted her, "Miss Qiao, why don't you tell us about it?"

"Alright, since you want to know, I'll tell you. Anyway, you'll need to know once it's implemented."

Clearing his throat, he began his mini-science lesson:

"Simply put, peanuts, soybeans, and sesame seeds can all be used to extract oil. The process is not difficult either, and it can be roughly divided into screening, roasting, grinding, steaming and frying, wrapping into cakes, pressing, filtering, sedimentation, and packaging."

She had prepared all of this in advance, and she spoke fluently and flawlessly, continuing, "The advantages of this cooking oil are very obvious."

As you can see, food fried in this oil has a bright color and a refreshing taste, and the oil hardly solidifies.

In contrast, peanut oil may experience some precipitation at low temperatures, but it will never completely solidify into a white solid like lard.

The three nodded. Indeed, once the temperature drops, a layer of white oil will form on the cooked dishes.

Qiao Jingjing continued, "This means it can be applied more widely to various cooking environments and methods, whether it's stir-frying, deep-frying, or cold dishes, it can bring out unique flavors and characteristics."

Furthermore, this method of oil extraction preserves the nutrients and flavor of the raw materials, resulting in a better taste.

Qiao Jingjing paused for a few seconds and then thought of something else: "This oil has another great advantage, which is that it is of high quality and low price."

Ordinary people can afford it.

In short, this is a traditional hand-pressing method of oil extraction that relies on human labor and simple tools, and it has many benefits.

Tantai Zhou stared at her, somewhat mesmerized, as she spoke eloquently. He had never seen such confidence and radiance on a girl's face before.

The flickering candlelight illuminated her face, making her skin appear delicate and hazy. Her eyes were bright and deep, like stars twinkling in the night sky, and her lips were slightly upturned, always carrying a faint smile.

A light, chilly breeze swept past the candlelight, causing the shadows on the wall to sway; soft strands of hair brushed against her cheeks, and a very faint fragrance wafted over, reminding Tantai Zhou of the scent she had worn before.

It felt like something had set off fireworks in my heart, scattering in all directions.

Looking at Miss Qiao, who was earnestly trying to answer her question, Tantai Zhou felt ashamed of his daydreaming.

"I've already had the oil pressing equipment made by a carpenter. I originally planned to launch it before the Chinese New Year, but after thinking it over, I've put it on hold. I don't know when I can launch it after the New Year."

Xuan Yi quickly asked, "Why? Can't such a good thing be implemented immediately?"

Qiao Jingjing didn't speak, but turned her gaze to Tantai Zhou, a hint of curiosity rising in her heart. She felt that this young man exuded an aura that was different from others, suggesting that he was not from an ordinary family.

This feeling is hard to describe, but it can be sensed from his demeanor and speech. His temperament is unique and noble, as if it were innate.

Looking at his subordinates beside him, each one appeared well-trained and utterly loyal. This indicated that his family background was profound and far beyond that of ordinary noble families.

Money can't solve everything in this world.

For example, a wealthy person can easily buy a servant with money; if he likes calligraphy and painting and wants to appear cultured, he can also buy works by famous artists. But if you want a truly loyal servant, or to immediately grasp the artistic conception of calligraphy and painting, you need a long period of cultivation and accumulation.

The reason why centuries-old families value their heritage is precisely because this level of refinement requires the collective effort of several generations. Only in this way can they cultivate loyal subordinates and ensure that their descendants possess noble character and refinement.

Thinking about this, Qiao Jingjing couldn't help but make more guesses about Tantai Zhou's identity.

"Young Master Tan should know the reason behind this, right?"

Tantai Zhou, whose name was mentioned, nodded subconsciously, "I did guess some of it."

Qiao Jingjing smiled and said, "Tell me about it."
