The girl traveled through another world and forced the prince to take the imperial examination

Madam Zhou hurried over to bring her a jar, which was filled with yellowish-brown salt that looked like coarse sand.

"This is boiled salt. It's the same salt you rich people eat, but it's filtered a little more often and ground a little finer than ours. I heard the salt the emperor eats is dug from deep wells. It's white as snow, not bitter or astringent. But that salt is so rare that even high-ranking officials can't eat it!"

Mu Qingcheng picked up a few grains of salt and put them in her mouth to taste. Sure enough, it was bitter and astringent, and her face immediately wrinkled.

He spat out the salt in his mouth with a bitter face, then scooped up some water to rinse his mouth, but the bitterness was still there.

Madam Zhou said with a smile, "My dear girl! This salt is bitter and astringent, it's not tasty. How about I make you a bowl of sugar water?"

Mu Qingcheng waved her hands and said, "Do you put this kind of salt in the buns you make? Why can't I taste the bitterness?"

Madam Zhou said, "Of course it's this kind of salt. Salt is so precious. Ordinary people only use a little bit when cooking, just to give it a salty taste. Those country folk can't even afford this kind of salt! They all buy black salt, and the dishes they cook are bitter. Our buns are fragrant because we use spices passed down from our ancestors, which suppress the bitterness of the salt, so you can't taste it."

Mu Qingcheng understood that the salt they ate here was sea salt. Unprocessed sea salt contained heavy metals and toxic substances, as well as high concentrations of sodium nitrite, all of which were harmful to the human body. Long-term consumption of unpurified sea salt was harmful to the joints, kidneys, and liver. It was like taking a chronic poison.

Mu Qingcheng suddenly felt that the Zhou family's buns were no longer delicious. No matter where she went in the future, she would have to eat this kind of coarse salt containing heavy metal nitrites. Coupled with the dark cuisine of the ancients, even if she had a fortune of ten thousand taels of gold, she would hardly live to see the day of her death.

It turns out that time travelers are not here to be idle. Mu Qingcheng put away her desire to give up. For the sake of her own life, should she do something?

Crude salt purification is junior high school knowledge, right? It doesn't mean that if you master math, physics, and chemistry, you'll be able to travel the world without fear. She's pretty good at math, physics, and chemistry, right? It's time to use knowledge to change your destiny.

Just as Mu Qingcheng rolled up her sleeves and prepared to do something powerful, there was a commotion outside the door.

"Madam, madam..."

It was Zhou Da who had returned. Madam Zhou came out of the kitchen and said, "Master, how come you're back so soon?"

Five or six people followed Mr. Zhou, some of whom were neighbors, and two women he didn't recognize. Mrs. Zhou asked in confusion, "Who are these two?"

Before Zhou Da could say anything, the woman rushed towards the barn.

"This is my ox, this is my ox! ... Miss Sun, please tell them quickly, is this my ox?"

The woman was so excited that she burst into tears and pulled Miss Sun forward to recognize the cow.

Miss Sun had an impatient look and a face full of disgust, and she only took two small steps forward reluctantly. She was wearing new clothes today, and she would be heartbroken if they were stained with cow dung.

"This cow looks quite similar, but I can't really tell. Why don't you ask my grandfather to take a look?"

She had already seen the cow, so she turned around and wanted to leave.

"You said this cow is yours?" A clear and pleasant voice came from behind the crowd.

Everyone turned around to see a girl in pink standing in the sunlight. Her skin was as white as snow, radiant and lustrous. Her jet-black hair was tied on either side, making her face look as small as a palm. Her almond-shaped eyes were slightly tilted, their dark, bright pupils shimmering with starlight.

Even the pink fine cotton dress could not conceal her elegant and refined temperament, which made people feel ashamed when they saw her and dared not to offend her.

It's no wonder that everyone was stunned and forgot to speak for a moment, because this town is so remote and they have never seen such an outstanding person before.

Mu Qingcheng looked around at everyone and set her sights on Miss Sun.

"It's you!"

Miss Sun was also startled when she saw Mu Qingcheng. She had been praised since she was a child, and everyone said she was a rare beauty in the area. She had never seen a girl more beautiful than her. Every time she went out, the boys' eyes seemed to be glued to her. Even the daughter of Mr. Liu in this town was only a little whiter than her and not as pretty as her.

Today she finally understood what a true beauty was. She was startled again when the beauty spoke to her.

"You, you know me?"

Mu Qingcheng was furious, but pretended to be calm and said, "I really don't know you! But I'm also curious, why did you insist on pulling me out of the car at the city gate yesterday? You looked so aggressive and scary! There were so many people around at the time, if you had pulled me out of the car, my reputation would have been ruined. Luckily, I had my brother to protect me, otherwise I would never have been able to get away!"

Mu Qingcheng imitated the teasing female villains in TV dramas in speaking, and it turned out to be very helpful in gaining popularity.

Everyone looked at Miss Sun with unfriendly eyes. Miss Sun felt uneasy instantly. She realized that this person was the woman who was praised as a fairy at the city gate yesterday. Could the young man she was looking for also live here?

If it were in the past, she would have left tactfully, but today she came just for that young man, so how could she leave without seeing him?

Miss Sun lowered her head and dared not say a word. Mu Qingcheng admired this little girl. She was so thick-skinned! Wasn't this girl about to leave? Why didn't she leave after she said a few words?

She turned her gaze to the woman again: "Who is this?"

Zhou Da hurriedly stepped forward and recounted what had just happened on the street. Mu Qingcheng also felt that this was probably the real owner of A Niu.

"Sister-in-law, are there any marks on your ox or cart? Or are there any birthmarks on the ox?"

The woman said, "My husband built this flatbed cart himself. It's made of four birch logs, each one enough to hold its own. He also found two ten-year-old elm trees for the shaft to make it stronger. After he finished building it, he said it was so solid it would last for eight to ten years without breaking down."

Mu Qingcheng asked Zhou Da and others to check the wood used for the cart, and it was exactly as the woman said.

The woman continued, "My husband is a carpenter. People from all over the town come to him to make furniture. Once the furniture is finished, he has to deliver it to people's homes. The furniture is large and heavy, so we often have to rent a car to deliver it. We live frugally, and six months ago we bought a yellow ox for fifteen taels. We bought it from the Sun family in Dahe Village."

Everyone looked at Miss Sun, who was feeling angry because of the secret accusations made by Mu Qingcheng just now.
