”Pack up, let’s go now!” Sage Apothecary shoved the letter into his disciple’s hand, hurried back to the house, packed a few pieces of laundry, picked up his medical kit and came out again.

　　Gu Ye opened the missive and read the contents, which were only a few words: Ye’er, please ask your master to come to the border for help, urgent! She studied the signature again, it was Gu Xiao’s.

　　Grandpa? Is he injured? Don’t tell me he braved the battlefield again? That’s not right! The medicine she gave her grandpa wouldn’t endanger life as long as the person has a breath left! Grandpa still wrote a letter, so it was definitely not him that needed saving. Could it be his savior, the old general?

　　Without pondering too much about it, Gu Ye rushed into her room, took out the large medical kit she was using as a cover, and pulled out the two healthy mules from the stable. While going out, she did not forget to tell Aunt Yan, “When my brother comes back from the mountain, tell him that I and my master went to Yan City for a medical visit. We won’t be back for ten days to half a month. Please take care of my brother while we are away.”

　　”Don’t worry, Miss, these are what I should do.” Aunt Yan hurriedly responded when she saw that the matter was urgent. But inwardly she was thinking, Should I report this matter to the Master?

　　”By the way, you’re almost cured, so don’t take the medicine prescribed by the old doctor. I have a bottle of pills here. Take two pills three times a day. In three days, your ailment will be completely cured. Can you make clothes? There is cloth and cotton in the room. Make two outfits for yourself to wear to replace the old ones. We’re leaving, and I’m entrusting the house to you. After Gu Ye finished speaking, she jumped on the back of the mule, followed after her master, and left in a rush.

　　Yan Qiutong watched Gu Ye leave, and a touch of emotion flashed in her eyes: Miss Gu was so anxious to go out, but she still did not forget her physical condition and whether she had any clothes to keep her out of the cold. She was indeed a kind little girl. She was a little resistant to this mission, but now she has a change of heart.

　　Saving a life was like putting out a fire. The master and apprentice rushed to the town with the fastest speed. The speed of a mule, after all, couldn’t keep up with a horse. So, Gu Ye knocked on the door of Jimin Pharmacy to try her luck.

　　Fortunately, Bai Jingxuan had not left the remote town yet. He and his entourage came from Yan City on horseback. Although their horses couldn’t be regarded as prime stocks, they were still much better than mules.

　　After a night of rest in Jimin Pharmacy, the master and the apprentice rode on their horses before dawn. Sage Apothecary has been roaming all corners of the world over the years, so he still knew the way to the border. The two rushed throughout the journey, changed horses twice, and finally arrived at Junlang Pass three days later.

　　At this time, there were large flakes of snowflakes floating in the sky. The whistling north wind whistled and rolled up the snow like goose feathers, rushing towards Gu Ye’s face. When she looked up, all that filled her eyes was yellow and desolation, which was gradually covered by snow. It looked so bleak.

　　”Hang on for a while, Junlang Pass is ahead.” Sage Apothecary’s voice emitted exhaustion. After all, he has reached an advanced age, and he was really overwhelmed by such a series of trips. Fortunately, his good apprentice was by his side. When he was resting overnight, she was always busy, and she personally served him food and drinks.

　　Gu Ye: If I don’t make it myself, how can I mix the anti-fatigue medicine into water and food?

　　Yes, if there was no medicine for Gu Ye, let alone a 70-year-old old man, even a sturdy young man would have collapsed after galloping on horseback every day from morning to night!

　　Gu Ye looked into the distance through the heavy snowstorm. In this frontier far from the prosperity and hustle and bustle stood an ancient and simple city. It resembled a weather-beaten grandpa with the vicissitudes of history, a station that lasted hundreds of years.

　　The ancient city wall of Junlang Pass, despite countless ups and downs, was still standing. It seemed like a guard protecting the frontier, always guarding the safety of the people with the pass. Junlang Pass had a quaint, simple and primitive aura. Over the years, the dark city wall, which has been ravaged by war, still shone with awe, just like a sword waiting to be unsheathed.

　　”Stop right there! Who are you?!” In the snowstorm, the guards who were standing upright found the presence of the master and the apprentice, and asked sharply.

　　”My grandfather is Gu Xiao, and he sent a letter for us to come!” Gu Ye dismounted from the horse in front of the city gate, quickly approached Sage Apothecary’s horse, and helped her master down to dismount.

　　Seeing that her master’s face was pale, she hurriedly pretended to take out the water bag from her arms, but she actually took it out of her space: “Master, you are exhausted. Take a sip slowly!”

　　Sage Apothecary took the water bag and drank the warm water with great gulps. The water was poured in the inn in the morning, but it remained warm in the cold wind for the whole day. The reason for it was something Sage Apothecary couldn’t care less to find out. After drinking half a bag of water, a warm feeling rose from his abdomen and reached every cell of his body. His frozen limbs regained their flexibility.

　　”It’s the doctor that General Gu invited! Quick, open the city gates and welcome them in.” An Adjutant General-like soldier and officer at the top of the city hurriedly came down from the city wall and welcomed them inside.

　　Gu Ye itched to inquire about information about her grandpa. She learned from the adjutant general that he suffered minor injuries in the last battle in order to save the Major General. They were all skin trauma. After five days of recuperation, he was fine. Her heart, which had been hanging all the way, completely settled down.

　　Grandpa’s promises can’t be trusted! He promised her that he would not go to the battlefield, yet he forgot it in a blink of an eye. Gu Ye was furious. Her little face was still stormy when she saw Gu Xiao!

　　Gu Xiao couldn’t care less about coaxing his granddaughter at this time. He rushed in front of Sage Apothecary, held his hand, and said earnestly, “Sage Apothecary, please use your healing hands and save the Eldest Young Master!”

　　”Let’s not waste time talking. Let me take a look at the injured first!” Sage Apothecary carried his medical kit and followed Gu Xiao into a room in the courtyard. Gu Ye also carried her large medical kit on her back and followed closely behind her master, for fear of being stopped.
