At the beginning, I was a rich female prisoner

At this moment, Nangong Lin was recalling the scene of being kicked by Yu Yunxin that day. Although her kick was extremely fast at that time, in his opinion, it was just the White Crane Spreads Wings and the Knee-hugging Step! That kick really hurt him for a while.

"What are you thinking about? These are just four moves, can't you learn them? There are still 24 moves waiting for you!" Seeing Nangong Lin in a daze, Yu Yunxin couldn't help but said, "Come on, do it for me."

As soon as the voice fell, Yu Yunxin watched Nangong Lin demonstrate the movements attentively. After observing for many times, she found that there were several places that were not done correctly, so she stepped forward to guide him personally. Facing Yu Yunxin who was touching her, Nangong Lin couldn't help but look at her. At this time, Yu Yunxin also raised her head, and their eyes met.

"What are you looking at! Concentrate on your studies!" Yu Yunxin scolded again.

When Nangong Lin heard this, he immediately gathered his mind and began to practice the first four forms of Tai Chi with full concentration. He was upright, his movements were slow and smooth, and each move was very steady and powerful.

Yu Yunxin quietly observed Nangong Lin's movements, with a hint of admiration in her eyes. When she saw Nangong Lin successfully soften his originally fierce moves, she couldn't help but smile with satisfaction and applauded: "Your Highness is really amazing! It is really admirable that he can understand the essence of Tai Chi in such a short time!"

Then, Yu Yunxin said enthusiastically: "Your Highness, let's practice these moves again on an empty stomach tomorrow morning to see how effective they are. You know, the most subtle aspect of Tai Chi is to counter the opponent's moves and to use the opponent's force to counter the opponent's force. No matter how fierce and sharp the enemy's fist is, we can overcome hardness with softness and return double the force." At this point, Yu Yunxin's face was filled with confidence and pride.

"I don't believe that my lady has such a powerful move." Nangong Lin showed an expression of disbelief on his face. He shook his head, seeming to be skeptical about everything he heard.

"You don't believe it?" Yu Yunxin asked with a chuckle. She casually glanced at the patrol guard who happened to pass by, and then whispered, "You, come here."

The guard heard the shout and hurried over, bowed his head and asked respectfully: "Princess, what can I do for you?"

"It's nothing serious. I just want you to come and fight with me for a few moves." Yu Yunxin replied with a smile, but there was a mischievous gleam in her eyes.

When the guard heard this, he was stunned. His face turned pale and he said in a trembling voice: "Princess...Princess, I dare not!" After that, he immediately knelt down, indicating that he absolutely dared not fight with the princess.

However, Yu Yunxin didn't care. She continued, "Don't be afraid. Go and call the other four guards in the mansion. You can join forces to attack me."

Soon the four guards arrived. Nangong Lin saw that the four guards his father gave him were all his former subordinates. They had trained in the military camp for more than ten years and their kung fu was among the best among tens of thousands of people. What did Yu Yunxin want to do? A woman taking on four, even if some of her kung fu was taught by General Zhenyuan, it would be impossible.

The guards looked at each other, their hearts filled with doubt and fear. One person didn't dare to take action, let alone four people attacking together? Wouldn't this put the princess to death? Their eyes involuntarily looked at the prince, hoping to get some instructions or help. However, the prince said nothing, just stood there quietly, as if observing everything.

The guards felt confused. They didn't know how to deal with such a situation. Faced with the princess's request, they could not disobey the order, but they were also worried about hurting the princess. After hesitating for a moment, they finally decided to act according to the princess's instructions. After all, if they went against the princess's wishes, the consequences might be more serious.

So, the four guards carefully gathered around Yu Yunxin, their expressions tense and serious, holding their weapons tightly in their hands, but not daring to attack easily. A seemingly tense duel was about to begin, and everyone held their breath, looking forward to what would happen next.

Yu Yunxin was actually quite nervous. If these four people could defeat her with one move, how could she still teach Nangong Lin Tai Chi? It would be better to let Nangong Lin teach her. However, she changed her mind and was still full of confidence in the origin and development of Tai Chi. After all, this set of boxing was taught to her by an old lady named Yang, and this old lady's family was once the orthodox inheritor of Tai Chi.

So, she signaled the four men to attack her from four different directions at the same time. She stood there calmly, and when the four men rushed over, she immediately performed Tai Chi. Her movements were as smooth and natural as flowing water, and she performed the 24 Tai Chi moves with great vigor, speed and sharpness. She used her flexible body to skillfully catch several punches from her opponents using the bow step and empty step. The last move of Tai Chi was to counterattack with the opponent's strength, and she pushed all four men back several meters away.

"The princess is so amazing!" The four of them were amazed and their admiration was beyond words.

"It's nothing special." Yu Yunxin smiled and said softly, "The boxing you four practiced focuses on strength. When you attack, you are very powerful, but a little stiff. I just use softness to overcome hardness. Oh, by the way, what are your four names?"

"We have no names and we are all orphans with no one to rely on. If Duke Li hadn't been so kind as to adopt us, we would have starved to death on the streets or frozen to death in some corner. Duke Lin was so kind to us and we have always wanted to repay him for raising us. Unfortunately, Duke Li got into trouble later on and we were still young, unable to avenge him. We could only obey His Majesty's orders and were transferred to the palace to serve as inner guards." Several people said with emotion.

"In that case, I will give you names. Why not name you after the twelve hours? You are now the guards of Prince Yu's Mansion, so just call yourself Yu Zi, Yu Chou, Yu Yin, and Yu Mao. How about that?" Yu Yunxin said with a smile.

"Thank you, Princess, for the name!" the four of them replied in unison, with a hint of gratitude in their eyes.

Yu Yunxin nodded with satisfaction, then scanned the area and selected four strong palace maids and four clever eunuchs. She secretly thought that these people could be trained to be her right-hand men.

"Why not let Prince Yu teach the twelve of you the four moves of Tai Chi. Tai Chi is a very powerful martial art that can strengthen your body and also provide self-defense. Although you may not necessarily become martial arts masters, it is always good to learn some basic moves." Yu Yunxin ordered.

Everyone agreed and expressed their willingness to learn Tai Chi. So, Nangong Lin began to teach them the moves and techniques of Tai Chi seriously. Yu Yunxin carefully observed everyone's learning situation and gave some guidance and suggestions from time to time.

Nangong Lin agreed with Yun Xin's words and vowed to practice this magical boxing technique. So the two agreed to continue practicing the next morning.

After observing for a while, Yu Yunxin could not wait to run to the various materials she had prepared yesterday - wood ash water, soap water, bath bean water, and bean dregs. These are all indispensable raw materials for making soap. She decided to filter the bean dregs water and part of the soap water herself.

Since making the ash water required some physical labor, she asked several eunuchs to help her complete the task, while she herself devoted herself to the production process and carefully recorded every step.

The next key step is to melt the lard and goat fat. She carefully heats them in different pots to make sure the heat is just right. Then, she pours fresh goat milk into the bath bean water, simmers it over low heat, and stirs it constantly until the solution becomes thick like paste. Then, she adds an appropriate amount of almond oil and continues to stir it evenly. Finally, she pours the mixture into various molds made by craftsmen and waits for it to cool and set.

It was the spring equinox, and the weather in Beijing was a little chilly, but this also allowed the soap to solidify quickly. Before long, pieces of goat milk soap with a rich milky aroma were successfully made. Yu Yunxin happily placed them on the table beside her, admiring the results of her hard work.

After teaching Tai Chi to several people, Nangong Lin felt a little exhausted. He sat down on a chair, his eyes caught sight of the white things on the table, and he muttered to himself, "Are these the cakes that the princess made for me? They look so tempting!"

Without thinking too much, he reached out and picked up a piece, put it in his mouth and took a bite. Hmm, it tastes quite fragrant!

However, at this moment, there was a sudden scream: "Your Majesty, spit it out quickly! What you ate was not cakes, but goat milk soap, which is specially used for washing face and bathing!"

The one who shouted was Yu Yunxin. With sharp eyes and quick movements, she quickly picked up a glass of water and ran towards Nangong Lin in a hurry.

Hearing this, Nangong Lin's face changed drastically, and he spit out the goat milk soap in his mouth without hesitation. He quickly took the cup of water that the girl brought, rinsed his mouth with big gulps, and after a few gurgling sounds, a few naughty bubbles appeared in his mouth. These bubbles were colorful and bright, which made people's eyes bright.

Seeing this, Yu Yunxin couldn't help laughing out loud. This smile was like a spring breeze, warm and pleasant; it was also like spring flowers blooming, gorgeous and dazzling. Her laughter seemed to have a magical power, which instantly relaxed Nangong Lin's originally tense nerves.

Nangong Lin looked at Yu Yunxin, who was smiling sweetly in front of him, and the corners of his mouth could not help but rise, revealing a slight smile. In the sunlight, her smile was brilliant and colorful, like a bright light, shining straight into the depths of his heart.

Seeing Yu Yunxin's bright and charming appearance, he could not help but feel an impulse in his heart, and he could not help but hug Yu Yunxin tightly in his arms. The palace maids beside witnessed this scene and could not help but whisper to each other, with envious smiles on their faces. And Li Ma also noticed the scene of the two people hugging each other, and the corners of her mouth rose slightly, and she smiled softly: "It seems that the love fragrance I placed that day worked, making the feelings of this pair of lovers even deeper."

Yu Yunxin was suddenly hugged. She looked at the people around her in panic, and immediately broke free from Nangong Lin's arms. She said coquettishly: "Nangong Lin, please wait for a moment here. I still have some key points about laundry soap to record down. After I finish, let's go out and play together, okay?" There was a hint of pleading in her tone, and her eyes were shining with anticipation.

Nangong Lin couldn't help but soften his heart after hearing Yu Yunxin's words, and nodded with a smile to show his agreement. He knew that Yu Yunxin always took things very seriously, and it was also a kind of enjoyment to watch her concentrate on completing her work.

Yu Yunxin was delighted to see Nangong Lin so considerate. She turned back to the table and continued to record the relevant matters of laundry soap with a focused and determined look. Nangong Lin stood quietly by her side, watching her silently, his eyes full of love and tenderness. At this moment, the whole atmosphere was filled with sweetness, as if time had stopped.

Nangong smelled the body fragrance left by Yu Yunxin in the air and said, "Okay, I'll wait for my lady." Then he sat down and ate the cakes brought by the palace maid.

Soon, soy milk soap and even the most common transparent wood ash soap were made. She asked the palace maids to use the transparent wood ash soap to wash clothes, and the rest were wrapped in paper and the name was written on them. After looking at them, she felt that they were too ordinary.

"Princess, this is the soap you mentioned." Nanny Yang, who was standing by, was also curious after seeing this scene.

Yu Yunxin looked at the stunned expressions of the others and smiled: "Come and help me pack."

Then she thought of making a beautiful package, so she picked up red ink, cinnabar and other pigments to paint natural goat milk soap, natural soy milk soap, and natural laundry soap, and asked Nangong Lin to write with her. Although Nangong Lin was stupid, her handwriting was still very dignified. Her handwriting was elegant and graceful, which was also due to her practice of calligraphy in modern times.

She thought about it and felt that this division of labor might be more efficient, so she decided to let Nangong Lin write about the laundry soap part, while she chose to write about goat milk soap and soy milk. Not only that, she also carefully drew simple and cute goat milk and soy milk patterns on the paper, adding some vivid elements to the text. After finishing, she casually drew a circle of leaves on the paper that Nangong Lin wrote, looked at her work, nodded with satisfaction, and then asked, "If we want to mass-produce it, will it be tiring?"

Chun Yu carefully examined the drawings in front of him and made a suggestion: "Princess, you can consider going to a printing house to print these designs. Moreover, if you use colored paper for printing and dyeing, the effect will be better."

Hearing this idea, Yu Yunxin's eyes instantly lit up. She looked at Chunyu with joy and praised sincerely, "Chunyu, you are really a smart, capable, and good housekeeper!"

Chunyu smiled slightly and responded modestly: "Thank you for your praise, Your Highness. In that case, do you intend to bring these soaps to the market?"

Yu Yunxin nodded without hesitation, expressing her agreement firmly.

After getting Yu Yunxin's approval, Chunyu made a prompt decision and took action immediately. She said firmly, "Okay, Princess, please rest assured. I will start to arrange the relevant matters of the printing office and repeatedly tell them to keep the secrets strictly." After that, Chunyu turned around and left, and began to prepare for the next work in full swing.

"By the way, remember to choose thicker colored paper. Don't choose the thin ones that will tear if torn! As for the size, it should be exactly the same as the one I'm holding in my hand." Yu Yunxin reminded in a tender voice, with a hint of excitement and anticipation in her tone.
