The next morning, Mu Nanhe went to the army training early. When he came back, he brought back the news that his leader agreed with Yang Qingyan's opinion, and brought back a work badge with Yang Qingyan's consultant written on it.

After breakfast, Yang Qingyan came to the R&D room of the army under the guidance of the soldiers with great expectations. As soon as she walked to the door of the R&D room, she could smell a faint medicinal fragrance, which was the smell of herbs and years, which made her feel at ease.

Walking into the R&D room, the furnishings inside are simple and plain, with several rows of old laboratory tables piled with various experimental instruments and medical books. Hearing the footsteps, the busy professors stopped their work and cast curious glances.

At this time, Director Li of the R&D Department came forward quickly with a warm smile on his face and introduced to everyone: "Comrades, let me introduce you to Comrade Yang Qingyan. In the previous epidemic, she relied on her wisdom and hard work to successfully develop new medicines and saved countless lives. Now Comrade Yang Qingyan has joined our R&D Department as a consultant. I believe that her joining can bring us new ideas and breakthroughs. Everyone welcomes her!"

The professors applauded, their eyes full of friendliness and expectation. Professor Zhang stepped forward, shook Yang Qingyan's hand tightly, and said with a smile: "Comrade Yang Qingyan, I've finally seen you here! We must communicate more in the future." Yang Qingyan smiled a little embarrassedly and responded modestly: "Director Li, Professor Zhang, seniors, I have done my best. In the future, I will have to rely on your care and help us contribute to the army together."

At this moment, a lively voice came from the door: "Oh, Comrade Yang Qingyan, I finally see you!" Yang Qingyan turned around, and saw a young girl with neat short hair running in. Her eyes were sparkling, and she had two sweet dimples when she smiled. Her cheeks were flushed because of running so fast, and she exuded a lively spirit.

"Hello, I'm Lin Yue. I'll have to learn more from you in the future!" Lin Yue walked up to Yang Qingyan and said enthusiastically.

Yang Qingyan smiled and held her hand: "Hello, Lin Yue, don't say that, let's learn from each other and make progress together."

After the greetings, Yang Qingyan quickly started her first research and development task - developing a fast and effective hemostatic drug. She knew that in the army, such a hemostatic drug was a lifesaver for the soldiers at a critical moment.

Under Lin Yue's guidance, she first came to the library, where Lin Yue introduced many books for reference.

Afterwards, Yang Qingyan went to the small warehouse behind the R&D room to select medicinal materials. The warehouse was filled with various kinds of herbs, and the different smells mixed together to form a unique atmosphere. She squatted down and carefully selected each herb one by one. With her rich experience, she could identify the quality of the herbs at a glance and pick out those that were damp and spoiled. While she was selecting, she silently calculated the appropriate dosage of each herb.

Everything was ready, and Yang Qingyan began her first experiment. She carefully put the selected herbs into the traditional clay pot according to the preliminary formula, and lit a small fire. She stared at the clay pot, not daring to be distracted, and her mind kept recalling the experience and skills accumulated over the years. As time passed, the color of the herbs gradually darkened, and the strong smell of medicine filled the whole room.

It was almost noon when Lin Yue walked into the laboratory quietly. Seeing Yang Qingyan still concentrating on the experiment, he said softly, "Qingyan, it's noon now. Let's go eat first and continue the research in the afternoon." Yang Qingyan came back to her senses, looked at the time, and said with a smile, "Oh, it's so late. Okay, let's go together."

At the door of the R&D room, Mu Nanhe and Chen Feng were waiting for them. Yang Qingyan saw the two of them, and a flash of surprise flashed in her eyes. She smiled and said, "Why are you here?" Mu Nanhe smiled softly and said, "I thought it was your first day in the R&D room, and you must be too busy, so I came to have lunch with you." Chen Feng scratched his head a little shyly and agreed, "Yes, sister-in-law, it's been a long time since we had lunch together."

Yang Qingyan then remembered Lin Yue beside her and quickly introduced: "This is Lin Yue, my new colleague. Lin Yue, this is Mu Nanhe, I'm 꺵꽬, and this is Chen Feng." Lin Yue greeted them generously: "Hello, I've heard of you for a long time, and today I finally get to meet you in person!"

On the way to the cafeteria, Lin Yue was like a cheerful little bird, chattering non-stop, sharing her childhood stories and imitating various small animals, making everyone laugh. Chen Feng just listened silently at first, occasionally agreeing with her, but gradually, he was attracted by Lin Yue's cheerful and generous personality, and his eyes always fell on her unconsciously.

In the cafeteria, the four of them found a seat and sat down. While Lin Yue was serving rice, she smiled and said, "The food in the cafeteria looks pretty good today. Come and try it." During the meal, Lin Yue was still the topic of conversation. She talked about some interesting rumors in the army and talked about an interesting book she had read recently. Her witty remarks made the whole lunch atmosphere relaxed and pleasant. Chen Feng looked at Lin Yue dancing with joy, and his affection for her became stronger. He would occasionally muster up the courage to talk to her.

In the afternoon, Yang Qingyan threw herself into the research and development work with full energy. She readjusted the formula of the herbal medicine, lit the small fire under the clay pot again, and started a new round of attempts with full concentration.

Every day after that, Yang Qingyan devoted herself to the research and development of hemostatic drugs with full energy. The laboratory was filled with medical books and herbs. She sat in front of the laboratory table, looking at the herbal juice boiling in the clay pot on the stove with a firm look in her eyes. This week, she was devoted to research and tried various formulas, but the test results were unsatisfactory every time.

In the hot laboratory, sweat kept pouring out of her forehead, wetting the hair at her temples, but she was calm. Every failure made her feel more stressed, but her belief never wavered.

Until the sixth day, the research reached a deadlock. No matter how it was adjusted, there was no progress. Yang Qingyan sat in the corner of the laboratory, feeling confused. Suddenly, she remembered a special experience in her life, and a key detail emerged in her mind. Her eyes lit up, and she immediately stood up and started a new attempt.

On the second day, Yang Qingyan added the supernatural water to a new batch of medicinal materials. After a long period of boiling and mixing, a new hemostatic medicine was born.

She found mice for the experiment and applied the medicine to the wound. A miracle happened. The wound stopped bleeding and healed quickly. Yang Qingyan was so excited that her eyes turned red. She succeeded!

She brought the results to the professors and showed them the experimental process. After carefully examining them, Professor Zhang exclaimed: "Comrade Yang Qingyan, you are amazing! The effect is beyond imagination!" Other professors also gave her admiring looks.

The hemostatic drug was approved by the professors and was soon put into clinical use. After the soldiers were injured, their wounds could heal quickly.
