"When you get out, return this to him if you get a chance."

Liu Ruyan gently stroked the old little box, tears silently sliding down from the corners of her eyes.

The wind blew gently outside the window, bringing a little coolness.

She couldn't help but shudder, her thoughts were pulled back to reality. She didn't know if he was still alive, if he still remembered her, if he still remembered the innocence and beauty they once had.

She stood up, walked to the window and looked out.

"Liu Ruyan, what are you doing? If you want to give it to her, just give it to her yourself. You haven't done anything yet, and you're already saying thank you. What a discouraging thing to say!"

Liu Ruyan smiled, "Okay, take it, please help me."

Shen Nianshu took it and felt its heavy weight, as if it carried all Liu Ruyan's thoughts and expectations.

Shen Nianshu took a deep breath and nodded firmly, "Okay, I will definitely find him and return this to him."

Shen Nianshu took it, and Liu Ruyan's face showed a happy smile. She patted the back of Shen Nianshu's hand gently and said softly, "Forget it, let's not talk about this anymore. I'll teach you something useful."

A trace of doubt flashed in Shen Nianshu's eyes.

Liu Ruyan took Shen Nianshu and turned to a corner of the room, where there were various bottles and jars with a fragrant aroma.

She gently picked up a delicate glass bottle, which contained a transparent liquid that exuded a faint floral fragrance.

"This is the essence of the jasmine flower, and you see, its color is as pure as the morning dew."

As Liu Ruyan spoke, he poured a few drops of liquid into a porcelain fragrance plate.

Shen Nianshu approached curiously and saw Liu Ruyan picking up another bottle. There was a dark brown liquid inside, exuding a rich woody aroma.

"It's sandalwood that, combined with the freshness of jasmine, creates a unique scent."

Liu Ruyan gently dropped a few drops of sandalwood essence, blended with the freshness of jasmine, and a mysterious and charming aroma filled the air.

Shen Nianshu closed her eyes and took a deep breath, as if she was in a fairyland far away from the hustle and bustle.

"Everything in the world has its own unique fragrance," Liu Ruyan's voice sounded leisurely, "Fragrance can be a kind of enjoyment, or it can be a weapon. It can soothe people's hearts, and it can also confuse people's senses."

She picked up a delicate perfume stick and stirred it gently on the perfume plate, blending the two aromas together perfectly.

Shen Nianshu's eyes widened and she looked at Liu Ruyan in disbelief.

She had never thought that this woman had such profound knowledge in perfume making.

"You...how can you still do this?" Shen Nianshu asked, her voice full of surprise and admiration.

Liu Ruyan smiled softly, a trace of pride flashed in her eyes.

She put down the perfume stick in her hand, turned around, looked at Shen Nianshu and said, "What's that look in your face? When it comes to perfume mixing, I'm second in the world, and I'm afraid no one dares to claim to be first."

Her words were full of confidence, as if nothing could trouble her. Shen Nianshu looked at her and couldn't help but feel respect in her heart.

Liu Ruyan smiled slightly, as if seeing through Shen Nianshu's inner surprise. She turned and walked towards a shelf with various spices, and gently rubbed the bottles and jars with her fingers, as if searching for the taste in her memory.

"Fragrance can not only have taste," Liu Ruyan said softly, while picking up a small porcelain bottle, "Some incense can be colorless and odorless, but it can play a huge role at critical moments."

She gently unscrewed the bottle cap, and an almost imperceptible faint aroma wafted out. Shen Nianshu moved closer curiously, trying to catch the faint breath.

Liu Ruyan smiled mysteriously and dropped a few drops of colorless and odorless liquid into an incense burner.

Instantly, the entire room was surrounded by an indescribable atmosphere.

Shen Nianshu felt as if her mind was drawn by the fragrance and entered an ethereal world.

Several minutes passed before Shen Nianshu came back to her senses. She looked at Liu Ruyan in amazement, her eyes full of admiration.

The aroma seemed to still linger in her nose, making her intoxicated and unable to extricate herself.

"What...what kind of fragrance is this?" Shen Nianshu couldn't help but ask, her voice full of curiosity and desire.

Liu Ruyan looked at her, a glimmer of satisfaction flashed in his eyes. She smiled softly, as if she had everything under control.

"This is a kind of incense called 'Menghui'," Liu Ruyan said softly, "it can take you back to the past and the deepest memories in your heart."

Her words seemed to have magic power, attracting Shen Nianshu's mind again.

"In this cold palace, conditions are limited, so we can only use the only flowers and plants to extract these."

Shen Nianshu's eyes widened, and her heart was deeply shocked by Liu Ruyan's words.

" That 's awesome." Shen Nianshu praised sincerely, her voice full of admiration and exclamation.

Watching Shen Nianshu's reaction, Liu Ruyan raised a proud smile on her lips. She walked to the window and looked at the scenery outside the window, as if she was lost in memories.

"You know, for me, perfume making is not only a skill, but also an emotional sustenance." Liu Ruyan said with emotion.

She turned to look at Shen Nianshu, with a determined light in her eyes, "Do you want to learn it? If you do, I will teach you. I don't want this craft to be lost."

Shen Nianshu knelt down in front of Liu Ruyan without hesitation, clasped her hands together, and kowtowed three times respectfully.

"Master, please bow to me, apprentice." Her voice was firm and powerful, full of admiration and gratitude for Liu Ruyan.

Liu Ruyan looked at her, his eyes shining with satisfaction. She gently helped Shen Nianshu up, patted her shoulder, and said softly, "Okay, hahaha , from now on, you will be my apprentice."

Shen Nianshu stood up.

"Thank you, Master!" Her voice was full of excitement and expectation.

Liu Ruyan looked at her with a smile, as if he saw the shadow of himself when he was young.

"To master the blending and prescription skills of essences, you need to have three aspects: identification, imitation and creation."

Liu Ruyan paused and then continued, "There are many ways to prepare spices. Commonly used methods include preparation, steaming, boiling, stir-frying, broiling, blasting, baking , flying, etc."

In the next few days, Shen Nianshu seemed to be deeply attracted by the world of perfumery. As soon as she woke up, she couldn't wait to go to Liu Ruyan's place.

"I didn't expect you to be quite talented. You are much faster than when I was learning." Liu Ruyan said.

"Today, I will teach you how to make incense."

She walked to a shelf with exquisite porcelain bottles, selected a few bottles of spices, and handed them to Shen Nianshu.

"Smell it first, what are these?" Liu Ruyan asked softly.
