After a conversation with Mr. Yan, Zhong Yuxiu gained a deeper understanding of the Yan family and felt more confident about the future. Having never met Mr. Yan's parents, she had no idea what they were like. Mr. Yan was a rare and open-minded man, not condescending like a superior, but rather compassionate towards her.

Faced with such an old man, all Zhong Yuxiu can do now is to show him more respect.

The last rays of the setting sun shone through the window, and Yan Rushan, who was busy in the kitchen, came out.

"Grandpa, Yuxiu, dinner is ready. Wash your hands and get ready to eat."

The conversation between Yan Guofeng and Zhong Yuxiu came to an abrupt halt. Yan Guofeng chuckled, "I'm going to wash my hands. I'm really lucky to have Comrade Zhong help me today. I can taste my eldest grandson's cooking skills."

"Grandpa, please try it later." Yan Rushan's ears moved slightly and turned red.

Zhong Yuxiu was numb from being teased. "Grandpa Yan, the bathroom is in the hallway next to it. You can see it when you go in."

Yan Guofeng nodded and went to the bathroom; Haonan and Tian Shangguo went to the kitchen to help set the table.

There were only two people left in the hall.

Yan Rushan stretched out his hand, a smile on his lips, "Yuxiu, come, let's go to the kitchen to wash our hands."

"I'm coming." Zhong Yuxiu stood up and walked over, but did not give him her hand. She walked past him and went to the kitchen.

Yan Rushan lowered his eyes to look at his empty hands, shook his head and smiled, then followed her; he washed his hands with her, and then set the table with Haonan, Tian Shangguo, and Goudan.

Yan Guofeng came out after washing his hands and looked at the table full of sumptuous dinner. When he saw the stewed beef that he had ordered, he immediately smiled.

"Is the beef stew made with radish? It looks delicious."

"Please try it first." Yan Rushan handed over a pair of chopsticks.

After Yan Guofeng took it, Zhong Yuxiu hurriedly invited him to the first seat; after Yan Guofeng sat down, he picked up his chopsticks and started eating the beef. The aroma of the beef was so tempting.

When you take a bite, the meat is chewy and the fishy smell is gone cleanly, leaving a lingering fragrance in your mouth.

"Good!" Yan Guofeng gave his thumbs up and asked his eldest grandson, "Did you do this, or did Goudan do this?"

"Gou Dan."

Yan Guofeng understood. "I don't think you can cook meat this delicious. Keep working hard. Back then, your grandfather and I worked in the kitchen squad. My old squad leader was a great chef before he joined the army. His cooking skills were unforgettable after eating them once. I even learned a few tricks from him."

"Then why don't you cook?" Yan Rushan choked him with a smile in his eyes.

Yan Guofeng: “.......” Could this grandson be fake?

Zhong Yuxiu pursed her lips and smiled softly, "Come on, Comrade Hao, Comrade Tian, ​​take your seats. Let's eat first and talk while we eat. If Grandpa Yan likes it, please eat more. If you want to eat more, come to my house and let Goudan make it for you."

"That's great." Yan Guofeng took the step and went down the slope. "Grandpa won't be polite with you. Come and play when you have time. Our family welcomes you anytime. When Dashan's parents come back, you can meet them too."

"Grandpa, eat." Yan Rushan served him the dishes, but he only gave him the carrots instead of the beef, which made Yan Guofeng stunned. Yan Rushan said, "Your body doesn't like too much greasy food, have you forgotten? Just eat a few bites."

Zhong Yuxiu looked up and asked, "What's wrong with Grandpa Yan?"

"The root cause of the disease is left over from the war in my early years. I can't stand the cold or the heat. When it's cold, my old cold legs will flare up. When it's hot, I become restless and irritable, and easily dizzy. The doctor said it's the three highs." Yan Rushan explained to her.

"Is that so?" Yuxiu silently recalled her ancient memories, wondering if there were any secret recipes for curing old cold legs. Three generations of ancient people had been single; in her third generation, she belonged to a prominent family with many secret recipes and folk remedies. To pass the time, she actually read quite a few. "I do know a folk remedy for rheumatism and old cold legs, but I don't know if it works. I haven't tried it."

Yan Rushan turned his head and asked, "What's the secret recipe? Is it convenient for you to tell me? If not, forget it."

Yan Guofeng pricked up his ears and listened.

"It's nothing inconvenient. I just happened to see it before and I have a good memory, so I remembered it." Zhong Yuxiu shook her head and continued, "Boil old ginger and grapefruit peels in water, and soak the whole leg in it to clean it. It's a simple method, but unfortunately, grapefruit peels are hard to come by in this season."

"I'll ask someone to get it and try." No matter what, any method is worth a try.

Zhong Yuxiu smiled and said, "Okay."

After dinner, after seeing off the Yan family's grandfather and grandson, Zhong Yuxiu turned around and said, "Goudan, come with me upstairs. I suddenly remembered a research project and need to collect data. Comrade Haonan, Comrade Tian Shangguo, I'll leave the downstairs to you."

"Okay, go ahead and get busy."

"If someone brings the materials later, please help me deliver them upstairs." Once the parts are in place and the shell is made, she can start making the surveillance camera.

Haonan and Tian Shangguo responded without hesitation.

After going upstairs, he closed the door and led Goudan straight to the laboratory. He closed the door of the laboratory again, isolating himself from the room. Then Zhong Yuxiu took out a stack of materials containing experimental data from the space.

I still remember participating in a drug research called Repair Fluid, which was a special product for Space Marines and could not be bought on the outside market.

The repair fluid can repair the body. Its medicinal factors are highly active and can revitalize the body from the root. The efficacy is very significant. Space Marines often go on missions, and injuries are commonplace. Having the repair fluid is equivalent to having an extra life, so each Space Marine will be given a bottle of repair fluid when they go on a mission.

Since the paper data could not be found, Zhong Yuxiu had to open the optical computer and search for information from the optical computer data; the optical computer could not connect to the main computer, but the data inside would not be lost.

"Found it."

Fortunately, I saved it at that time, otherwise, I wouldn’t be able to find it now.

Retrieved the relevant information of the repair fluid and compared it with the data in memory; after confirming that the saved data was correct, he began to write down the medicinal materials needed for the medicine, and then improved it in combination with the current herbs.

The current data is based on medicinal materials that can be grown in interstellar space, which is different from the current era. We have to find alternative medicinal materials.

This is a big project.

After writing down the data, she realized that her understanding of medicinal materials was incomplete and could not be matched at will; she needed to start from scratch to gain a deeper understanding of medicine, so this research had to be shelved temporarily.

It's not that she doesn't want to give away the prescription, but it's useless even if she does; the people here have never even heard of the medicinal herbs from the interstellar era.

"Master, once the repair fluid comes out, it will definitely cause a sensation. Back then, in the interstellar space, the release of the repair fluid also caused quite a stir." Goudan analyzed the environment based on his master's situation and, with his master's safety as the top priority, had to remind him.

Yuxiu nodded. "I know, but I won't touch it for now. I still need to read more medical books and consult with medical experts. I will only start researching it when the time is right."

The repair fluid data is placed in the storage ring so that it is not afraid of being stolen and is very safe.
