Lin Zhiyue ended her busy and fulfilling first day at the Military Region Research Institute and opened the door of her home with a heart full of joy and a little fatigue.

Wen Yu and Lin Lang, who were anxiously waiting in the living room, stood up immediately and walked quickly to the door when they heard the door open.

Wen Yu's eyes were full of concern. She stepped forward and took Lin Zhiyue's hand, looking her daughter up from head to toe, and asked distressedly: "Yueyue, you are finally back. How was your day at the research institute?"

Lin Lang followed closely behind, frowning slightly, with a bit of worry and concern: "Yes, my girl, is your work going well? Is anyone bullying you? Are you tired?"

Wen Yu pulled her daughter towards the sofa, muttering, "Child, I don't know if you've eaten enough outside. Mom left some food for you. Eat it later."

Lin Zhiyue looked at her parents' anxious and concerned expressions, and a warm feeling surged in her heart. A bright smile bloomed on her face, and she quickly said, "Dad, Mom, don't worry. Everything went very well for me at the institute today."

She patted Wen Yu's hand gently, signaling her to rest assured, "The seniors in the institute have taken special care of me and are very kind to me. Not only did they patiently answer my questions, they also taught me a lot of new knowledge and research methods."

At this point, Lin Zhiyue tilted her head slightly and smiled mischievously: "I'm not tired at all. I feel like time has passed too quickly. I haven't studied enough of many things."

Wen Yu and Lin Lang looked at each other, and the worry in their eyes gradually dissipated, replaced by relief and pride.

Wen Yu smiled and touched Lin Zhiyue's head: "It's good that you're okay, it's good that you're okay. As long as you're happy, we'll be relieved."

At this time, Wen Yu brought out the steaming hot food from the kitchen and called out, "Stop chatting and come and eat. The food is getting cold. Today I specially made your favorite sweet and sour pork ribs and stir-fried seasonal vegetables. Come and try them."

Lin Zhiyue walked to the dining table, took a deep breath, and exclaimed: "Wow, it smells so good! My mother's cooking is still the best for me."

The family sat around the dining table, eating and chatting.

Lin Zhiyue shared interesting people and things in the institute. When she talked about a little joke told by a senior, her parents laughed out loud, and a warm atmosphere filled the whole house.

After the meal, Lin Zhiyue took the initiative to clean up the dishes. Wen Yu wanted to help, but she gently pushed her away: "Mom, you are tired today, just take a rest, I can do these."

Seeing her daughter's sensible appearance, Wen Yu's eyes were filled with emotion.

After cleaning up the kitchen, Lin Zhiyue returned to her room, turned on the desk lamp, sat at the desk, and prepared to organize the notes she had taken at the research institute today.

She recalled the day's experiences and felt motivated.

At this time, Wen Yu knocked on the door gently and walked in with a cup of hot milk in her hand: "Yueyue, drink a cup of milk, go to bed early, and don't tire yourself out."

Lin Zhiyue took the milk and nodded in thanks: "Thank you, Mom. You should go to bed early too."

After Wen Yu left, Lin Zhiyue took a sip of milk, feeling the warmth spreading from her throat to her whole body.

The next morning, just as the sky was turning pale, Lin Zhiyue walked into the gate of the Military Region Research Institute in high spirits.

At this time, the institute was still shrouded in a faint silence, with only the early birds chirping on the branches, as if cheering for the arrival of a new day.

Lin Zhiyue walked straight to his work area, skillfully put on his white coat and gloves, and quickly started the intense and busy work of gun modification.

In front of her were piled all kinds of sophisticated instruments, design drawings, and disassembled gun parts.

She carefully picked up one of the key parts and observed it carefully, her eyes revealing concentration and persistence, not missing any details.

In the days that followed, Lin Zhiyue almost "nailed" himself to the research institute.

Every day, she is always the first to arrive and the last to leave.

When I was hungry, I just ate a few bites of the working meals provided by the institute;

When I feel tired, I just lie on the table and take a nap.

She had to calculate and verify every piece of data repeatedly;

She has intense discussions and analyses with her team members on every design detail.

In this way, time passed quietly in the intense and fulfilling work, and half a month passed in a flash.

During this half month, the institute witnessed Lin Zhiyue's hard work and dedication, as well as her growth and transformation.

Finally, on a sunny morning in the laboratory, Lin Zhiyue and her team successfully developed the modified firearms.

When the gun that embodied countless efforts was presented in front of everyone, the entire laboratory instantly boiled over.

Old Li stared at the brand new weapon, his eyes gradually becoming moist, tears welling up in his eyes uncontrollably, his lips trembling slightly, and after a long time, he repeated in a crying voice as if mumbling to himself: "Success, it's really successful!" His voice was not loud, but it seemed as if he had used up all his strength.

He slowly raised his head, his eyes passing through the walls of the laboratory, as if he saw those figures fighting bloody battles on the battlefield, his voice choked with sobs: "If we had our own weapons earlier, they wouldn't have died..."

The voices and smiles of those fallen comrades appeared in his mind one by one, and each picture was like a sharp knife, piercing his heart.

Over the years, due to the gap in weapons and equipment, comrades-in-arms faced huge dangers when performing their missions, and countless lives were lost on the battlefield forever. This heavy grief and guilt has always weighed on Mr. Li's heart.

At this moment, the joy of success and the longing for the sacrificed comrades were intertwined, making Mr. Li unable to suppress his inner emotions any longer. Tears burst out of his eyes and slid down his weathered cheeks.

The researchers nearby were equally excited; some shouted excitedly, some clapped loudly, and then everyone hugged each other, their shoulders trembling slightly. They hugged each other tightly, expressing their inner joy and excitement in the most direct way.

They have put in so much effort for this moment, working hard for countless days and nights, and starting over again after countless failures, and finally ushered in the dawn of success at this moment.

Their cheers were like surging waves, one after another, echoing throughout the institute.

The cheers were so loud that even the dean, who was busy in his office, was alarmed.

The dean put down the documents in his hand, with a puzzled look on his face, walked out of the office quickly, and hurried in the direction of the sound to check the situation.

When the dean walked into the laboratory and saw everyone gathered together with the newly developed weapon placed in the middle, he instantly understood everything.

He was stunned for a moment, then a smile of surprise and pride appeared on his face. He walked quickly into the crowd and said excitedly: "Great, you are really amazing! This is the pride of our institute and the pride of the military region!"
