Lin Yue is well aware of this, but at the same time, Yue Jinge's business is facing an unprecedented crisis under the malicious competition of its rivals. If it is not careful, it may be destroyed. This makes Lin Yue in a dilemma.

In a room filled with ancient books and brocade handkerchief research materials, Lin Yue devoted herself to her studies day and night. She repeatedly compared the text in the ancient books with the patterns on the handkerchiefs, trying to find the hidden connections. Ah Xiang and Aunt Wang, feeling sorry for her, often brought her tea and snacks, urging her to rest, but Lin Yue always waved her off, her gaze never leaving the mysterious symbols and lines.

"Ms. Lin, you haven't slept well for several days. Your health is very important." Aunt Wang said worriedly.

Lin Yue rubbed her sore eyes and forced a smile: "Aunt Wang, I'm fine. This mystery is about to be solved, how can I stop?"

Meanwhile, Ah Fu was overwhelmed at Yue Jin Pavilion. Qing Feng Zhai, along with several other businesses, had launched a fierce price war against Yue Jing Pavilion, resulting in a sharp drop in customer traffic and a sharp decline in sales. The embroiderers began to panic, fearing they would lose their livelihoods. Ah Fu struggled to calm everyone's nerves while also trying to find a way to deal with the competition. However, despite his best efforts, he struggled to find an effective solution.

In desperation, Ah Fu rushed to Lin Yue's residence and told her everything about the store. Lin Yue's brow furrowed, her heart filled with anxiety. She knew Yue Jing Pavilion was the fruit of everyone's hard work and couldn't afford to fall. However, solving the mystery of the handkerchief was crucial to her return home, and she couldn't afford to lose it either.

"Afu, go back and stabilize the situation first. Tell the embroiderers that our 'Yuejing Pavilion' will not be defeated easily. I will come up with a countermeasure as soon as possible." Lin Yue said in a firm tone.

After Ah Fu left, Lin Yue fell into deep thought. She knew she had to find a way to save Yuejing Pavilion while still exploring the secret of the handkerchief.

Suddenly, an idea struck her. Yuejingge's handicrafts and skincare products were renowned for their unique designs and exceptional quality. If she could build on this legacy by incorporating elements related to brocade patterns into a new product line, perhaps it would both attract customers and further explore the mysteries of brocade.

After coming up with the idea, Lin Yue immediately gathered A Xiang and several experienced embroiderers and told them about his idea.

Everyone nodded in agreement. They then worked together to design new handicrafts. The embroiderers skillfully incorporated the lines and symbols found on the brocade handkerchiefs into their embroidery patterns, creating a series of exquisite handkerchiefs, sachets, and screens. As for skincare products, Lin Yue combined herbal formulas from ancient texts with modern skincare knowledge to develop moisturizers and facial masks with mysterious patterned packaging.

The new product line was an instant success. Customers, drawn to the unique designs and mysterious aura, flocked to buy. Yuejing Pavilion's business gradually picked up, with customer traffic and sales rebounding. Meanwhile, Lin Yue made new discoveries while researching brocade handkerchiefs and ancient books.

She noticed that some of the astrological changes recorded in ancient texts coincided with the lines of certain patterns on the handkerchief. After repeated calculations, she discovered that these astrological changes seemed to correspond to important historical events in the Tang Dynasty. Lin Yue realized that the handkerchief pattern not only related to her time travel, but also potentially foreshadowed the future of the Tang Dynasty.

Just when Lin Yue was overjoyed at this great discovery, bad news suddenly came: a rare epidemic broke out in the city, and many people were infected with high fever and were in critical condition.

The epidemic spread rapidly, plunging the entire capital into panic. Yuejing Pavilion's business was once again affected, with customers staying away from their doors and the shop deserted.

Lin Yue looked at the deserted streets, her heart filled with worry. She knew that saving the people from the epidemic was the most urgent task. Recalling her modern medical knowledge and the herbal formulas recorded in ancient texts, Lin Yue decided to try to develop a cure for the epidemic.

Together with Ah Fu, Aunt Wang, and others, she collected herbs from far and wide and set up a simple medicine workshop in the backyard of Yuejing Pavilion. Lin Yue worked day and night in the workshop, combining and brewing various herbs according to records in ancient books and her own understanding. After many attempts, she finally developed a potion.

Lin Yue brought medicine and went to the homes of patients with the epidemic in person to bring them hope.

Thanks to her efforts, some patients' conditions began to improve. As word spread, more and more people came seeking help. Lin Yue and the staff of Yuejing Pavilion worked tirelessly day and night to prepare medicine and distribute it free of charge to patients.

As the epidemic was gradually brought under control, the capital slowly regained its prosperity. Yuejing Pavilion's reputation soared, and business became even more prosperous than before. This was truly a blessing in disguise.

While treating patients, Lin Yue also gained a deeper understanding of the patterns on the handkerchiefs. She discovered that some of the symbols in the patterns seemed to have some mysterious connection with the spread and treatment of the epidemic.
