Qin An Ning shook her head lightly, a relieved smile on her face. "It's not that bitter or not. Aren't we all doing well now?"

She understood that no matter how sad or regretful she was, the facts could not be changed, and people should look forward instead of indulging in memories of the past.

Otherwise, it will only bring more pain and trouble to those around you.

"Dad, let the past be the past. We must look forward. The future will definitely be better."

Qin Zhen didn't expect that Qin An Ning not only didn't blame him, but also comforted him considerately.

A warm feeling surged in his heart, but at the same time he couldn't help feeling a pang of sadness.

If Zhilan were still alive, she would surely feel very relieved to see such a well-behaved and sensible daughter!

"Okay, let's look forward, look forward." Qin Zhen murmured.

Qin Anning had been traveling all the way by car and was already exhausted. After talking with Qin Zhen, she went back to her room, washed up, lay down on the bed, and soon fell asleep.

Lu Cheng originally wanted to talk to her, but he didn't even have the chance to open his mouth.

Looking at his wife's peaceful and sweet sleeping face, he smiled helplessly, carefully tucked the corners of the quilt for her, then lay down gently, closed his eyes, and fell asleep with the sound of her breathing.

After a day of rest, Qin Anning once again plunged into his busy work, shuttling between the laboratory and checking materials all day long.

Finally, in mid-December, she successfully developed the formula for the healing potion for hidden injuries.

"Dad, I remixed this prescription based on the efficacy of the herbs in the space. All the ingredients have been replaced with herbs that can be found today.

Although the effect is undeniable, I cannot give an accurate estimate of how long it will take to achieve recovery due to the lack of experimental data.

Qin Zhen held the thin piece of paper tightly, looking at it again and again, as if it weighed a thousand pounds.

"It doesn't matter. It's not easy for you to develop such a drug. With this drug, many people won't have to retire due to injuries, and the talents we trained will not be lost so quickly." Qin Zhen replied with great emotion.

Then he asked, "Ningning, would this medicine be more effective for people who have just been injured?"

Qin An Ning nodded slightly, "The function of the medicine is to restore hidden injuries. Essentially, it promotes cell remodeling and repair of damaged parts.

The younger you are, the stronger your cells' ability to repair themselves. Similarly, old injuries naturally recover differently than new ones.

If there is data support, perhaps the formula can be improved later.”

However, this drug is specifically used on soldiers after all, and it takes a certain period of time to fully recover. She has no way of continuously tracking and recording the data of every person who takes the drug in detail.

After hearing this, Qin Zhen fell into deep thought, wondering whether he could ask the military hospital for cooperation to complete the data recording work, or simply let the troops be responsible for distributing these medicines and let the medical staff in the troops perform the relevant data recording tasks.

This is not impossible. Although he has selfish motives to help Ningning, if the prescription can be successfully improved, the soldiers will still benefit. It won't be considered as abusing his power for personal gain!

"Ningning, I have to go find Commander Chen and Commander Zhu to discuss how to produce and distribute this medicine. You two should go to bed early and don't have to wait for me." After saying that, he hurried away.

Qin An Ning looked at the heavily closed door and burst out laughing, "Why is Dad so impatient? This is the first time I've seen him like this."

"I'm just worried. My dad has devoted all his energy to the army. Every time he sees a soldier having to retire due to injury, he feels really bad.

Especially those elites, who are talents carefully cultivated by the army. Losing them is a huge loss to the army.

Now that he has this drug that can solve the problem, he certainly wants to produce it as soon as possible."

"You seem to know my dad very well!" Qin An Ning said as she peeled a slice of orange and stuffed it into Lu Cheng's mouth.

Lu Cheng showed a smug look on his face, and he deliberately raised his chin and said, "Of course. A son-in-law is half a son. If I don't understand my father, how can I better respect him?"

Qin An Ning smiled slightly after hearing this, handed the two remaining orange halves in her hand to Lu Cheng again, and asked casually, "By the way, did Mom and Dad say when they're coming over? Anyway, it's winter now, and there's nothing to do at home, so why not ask them to come over and play!"

"I asked before, and they said we have to wait for a while and then come directly to attend my eldest brother's wedding." Lu Cheng replied.

Due to work reasons, Qin Anning often needs to conduct long experiments, sometimes standing for several hours.

Every time she gets home from work, she always complains about her legs aching.

Whenever Lu Cheng has free time, he will take the initiative to massage her calves to relieve fatigue.

He had just finished massaging his left calf, and then naturally turned to the right side to continue kneading.

Qin Anning lay comfortably on the sofa and enjoyed Lu Cheng's service. "But Big Brother's wedding is not until February. Why wait so long? Are they afraid of bothering us and not coming?"

"I think I should call my third sister tomorrow and ask her to buy the tickets for them, so they can't come even if they don't want to!" Qin An Ning suggested.

"You can do this. If I do it, they will definitely scold me when they come." Lu Cheng curled his lips after saying this. His family status is worrying now.

Qin Anning chuckled and said, "Okay, I'll do it."

Lu Cheng narrowed his eyes and looked at Qin An Ning, "You're still smiling, are you happy that I'm of a lower status?"

"Family brother position, how high do you want to go?"

"I'll let you see how tall I can be." After Lu Cheng said that, he picked up Qin An Ning and walked towards the bedroom.

After completing the formula of the hidden injury medicine, Qin An Ning devoted himself to the research and development of anti-cancer drugs, and was busy for several days.

She was doing experiments at work that day when Qin Zhen called her.

Qin Zhen's serious voice came from the other end of the phone, "Ningning, come back now, I have something to tell you."

Not knowing what was going on, Qin Anning didn't dare to delay. He said something to Niu Jiancheng and drove back in a hurry.

When the car approached the gate of the military area, Qin Anning saw Pan Feng standing there waiting for him from afar.

When she was about to get out of the car to register, Pan Feng had already sat in the passenger seat, "Let's go, I've finished registering for you."

"What happened? Why did my dad send you out to pick me up?" Qin An Ning asked with a puzzled look.
