At this moment, a burst of hurried horse hoof sounds came from afar. Sheng Yunrong and Xiang Zhu immediately stood up alertly, only to see a figure galloping towards them.

The man came to Sheng Yunrong, dismounted, and panted, "Miss Sheng, my master has a letter for you."

Sheng Yunrong took the letter and opened it. It turned out to be from her father, Mr. Sheng. The letter said that something happened at home and hoped that Sheng Yunrong could return home as soon as possible.

Sheng Yunrong had a complicated expression after reading the letter.

She turned to Xiang Zhu and said, "Xiang Zhu, we need to speed up and get to the border as soon as possible."

Xiang Zhu nodded without asking any more questions. They were on their way again, each with their own plans in mind.

Finally, they arrived at the border. Sheng Yunrong looked at the prosperous border in front of her and was very excited.

At the border, Sheng Yunrong and Xiang Zhu met many people and collected a lot of useful information.

However, at this time, Sheng Yunrong suddenly fell ill. She lay in bed, pale and weak. Xiang Zhu looked at Sheng Yunrong anxiously, his eyes full of worry.

Sheng Yunrong looked at Xiang Zhu and said with a smile: "Xiang Zhu, I'm not afraid. I believe you will accompany me through this difficult time."

Xiang Zhu burst into tears. She held Sheng Yunrong's hand tightly and said, "Miss, I will stay with you until you recover."

Under Xiang Zhu's careful care, Sheng Yunrong finally recovered. She looked at the bright sunshine outside the window, her heart full of hope.

She knew that she was only one step away from the truth. And Xiang Zhu always stayed by her side to protect her.

It turns out that the disappearance of Mr. Sheng is related to a conspiracy at the border. Sheng Yunrong decides to uncover the conspiracy and clear her father's name.

With the help of Xiang Zhu, Sheng Yunrong successfully uncovered the truth of the conspiracy. She handed the evidence to the government, and the government immediately launched an investigation.

In the end, Mr. Sheng's grievances were redressed, and he returned home to reunite with Sheng Yunrong and Xiang Zhu.

Sheng Yunrong looked at her father with gratitude in her eyes.

She turned to Xiang Zhu and said, "Xiang Zhu, thank you for accompanying me through these difficult days."

Xiang Zhu smiled slightly and said, "Miss, this is what I should do. As long as I can follow you, I will be satisfied."

Sheng Yunrong was moved and hugged Xiang Zhu, with a warm current in her heart. She knew that the relationship between them had surpassed the master-servant relationship and became a friendship of life and death.

From then on, Sheng Yunrong and Xiang Zhu continued to stay by the side of Master Sheng and guard this home together.

…

The tunnel was winding and led to more than one place. Sheng Yunrong, carrying her bag, followed Xiang Zhu and a caravan heading to the border to do business.

"Miss, this tunnel is so winding, can we really reach the border?" Xiang Zhu frowned and asked worriedly.

Sheng Yunrong smiled slightly, her eyes firm: "Xiang Zhu, have you forgotten the ancestral motto of our Sheng family? No matter how difficult and dangerous the obstacles are, we must move forward courageously."

Xiang Zhu's expression eased after hearing this, but he was still a little uneasy: "But, Miss, this tunnel is dark and scary. What should we do if something unexpected happens?"

Sheng Yunrong gently patted Xiang Zhu's shoulder and comforted him, "Don't worry, Xiang Zhu, I will protect you. Besides, the caravan is full of experienced merchants, they will protect us."

As they were talking, they had already walked out of the tunnel and into an open area. The captain of the caravan was waiting there, and when he saw them coming out, he immediately came to greet them.

"Miss Sheng, we finally found you. Please come this way. We have prepared your luggage and are ready to set off at any time." The captain said enthusiastically.

Sheng Yunrong nodded slightly and looked at the captain gratefully: "Thank you, Captain. We will catch up right away."

The caravan was moving very fast, and along the way, Sheng Yunrong and Xiang Zhu gradually became familiar with the members of the caravan. They told each other about their experiences, which gave Sheng Yunrong a deeper understanding of the situation at the border.

That evening, they camped in a wilderness. Sheng Yunrong and Xiang Zhu sat by the fire, looking at the twinkling stars in the sky, each with their own feelings.

"Miss, do you think our trip will be successful?" Xiang Zhu looked up at Sheng Yunrong, his eyes flickering with worry.

Sheng Yunrong smiled and shook her head gently: "Xiang Zhu, life is full of uncertainties. What we have to do is to face them bravely and do our best."

Xiang Zhu listened, and his expression became much firmer: "Miss, don't worry, I will always be by your side and face everything together."

As the night deepened, Sheng Yunrong and Xiang Zhu lay on the grass beside them, looking at the starry sky, their hearts full of anticipation. They knew that this trip to the border would be a new challenge and also an opportunity for them to grow.

The next day, the caravan continued to move forward. On the way, Sheng Yunrong and Xiang Zhu encountered various difficulties, but they both overcame them one by one with their firm beliefs.

That day, they came to a place called "Fenglingdu". It was located at the border, with raging sandstorms and a harsh environment. Sheng Yunrong frowned at the scene in front of her.

"Miss, the wind and sand here are too strong. How are we going to get through?" Xiang Zhu covered his mouth and asked worriedly.

Sheng Yunrong pondered for a moment, then said to the captain: "Captain, do you have any way to get us through here safely?"

The captain frowned and said in a deep voice: "There is a way, but it requires risk. We have to use the wind to quickly pass through this desert."

Sheng Yunrong listened, her eyes firm: "Then please lead the way, we are willing to take the risk."

Led by the captain, the caravan began its adventure across Fenglingdu. Sheng Yunrong and Xiang Zhu held on to their horses tightly, enduring the invasion of wind and sand, and galloped all the way.

Finally, after a long and arduous journey, they successfully crossed Fengling Ferry. Sheng Yunrong and Xiang Zhu looked at each other, tears of joy flashing in their eyes.

"Miss, we succeeded!" Xiang Zhu excitedly held Sheng Yunrong's hand, tears streaming down his face.

Sheng Yunrong smiled and patted Xiang Zhu's hand: "Yes, we succeeded. Xiang Zhu, thank you for always being by my side."

In the following days, Sheng Yunrong and Xiang Zhu continued to follow the caravan. They saw all kinds of goods in the border market and made many friends.

On this day, Sheng Yunrong and Xiang Zhu were tasting local delicacies in a restaurant. Suddenly, a familiar figure walked in.

"Miss Sheng, Miss Xiangzhu, you are here too?" The man who came was Sheng Yunrong's cousin. Meeting an old friend in a foreign place, the three of them immediately started talking enthusiastically.

Sheng Yunrong smiled and said to her cousin: "Cousin, we are preparing to go to the border, what about you?"

My cousin sighed and said, "I have been ordered to stay here and cannot leave in the short term."

After hearing this, Sheng Yunrong said with a firm look in her eyes: "Cousin, don't worry, we will definitely complete the task smoothly and contribute to the prosperity of our country's border."

The cousin looked at Sheng Yunrong with approval in his eyes: "Miss Sheng, I believe you can do it."

Under the care of their cousin, Sheng Yunrong and Xiang Zhu spent a happy time at the border, where they learned about the customs and folkways of the people and felt the hardships of the people.
