Early in the morning, Qin Lan opened her eyes and was surprised to see Lin Chen asleep on the chair beside the bed.

Qin Lan tried to sit up from the bed, and suddenly realized that her wound didn't hurt at all.

When she unwrapped the bandage from her wound, she was shocked—it had healed miraculously.

"How is that possible?" There's a saying that it takes a hundred days to recover from bone or muscle injuries, yet after applying Lin Chen's medicine for just one night, the injured area felt as if it had healed.

Qin Lan quietly got out of bed and picked up a blanket to cover Lin Chen.

Just then, Lin Chen suddenly opened his eyes and rubbed his blurry eyes, "Awake?"

"Hum, did you sleep on the chair all night?" Qin Lan said somewhat apologetically.

Lin Chen smiled, stretched, and stood up, "It's fine, a quick nap does me good."

Qin Lan was moved, "Lin Chen, thank you for saving me."

"Haha, don't be so formal with me, you are my..."

"You're still talking!" Qin Lan's cheeks flushed with a mix of shyness and anger as she picked up a pillow from the bed and threw it at him.

"Alright, I won't say anymore. But what exactly happened yesterday, and why didn't you let me take you to the hospital?" Lin Chen asked curiously, catching the pillow.

Qin Lan sighed, "The person who tried to kill me yesterday must have been sent by the Du family. I've been investigating a murder case recently and I suspect that it's related to Du Wei. I didn't expect the Du family to be so heartless as to hire an assassin to kill me."

"Not Du Wei again!" Lin Chen furrowed his brows.

"You know him too?" Qin Lan asked in confusion.

Lin Chen nodded, "I just taught him a lesson yesterday."

"You taught him a lesson?" Qin Lan was stunned on hearing this, knowing that Du Wei was a little tyrant in DY that no one dared to provoke; she had only ever heard of him beating up others, never being challenged himself.

Lin Chen briefly explained what had happened, and Qin Lan laughed, unable to contain herself, "Well done, that guy deserves to be beaten up."

"What about the murder case? Why didn't you let me take you to the hospital yesterday?" Lin Chen inquired.

Qin Lan gave a wry smile, "A few days ago, a battered female corpse was found in the outskirts of DY. A lot of evidence pointed to the Du family's eldest son, Du Wei. But just two days ago, the case was abruptly closed, claiming that an old scavenger did it, and that person had already been arrested."

"Are you suggesting that the old scavenger was wrongfully accused?" Lin Chen felt something stir in his heart.

Qin Lan nodded, "I visited the old man's home, he was very simple and honest, supporting five impoverished children through college by scavenging trash, plus he had a very good reputation amongst the neighbors. I suspected he was framed, but just as I was preparing to interrogate him, he hanged himself in his cell."

"If the old man was framed, then this Du Wei, he really deserves to die," Lin Chen said, clenching his fists in anger.

"The bureau has already closed the case, but I feel there are too many unanswered questions. I want to give justice to the old man and the girl, so I need to continue the investigation. I already have some leads. The fact that the Du family sent an assassin after me only proves they're guilty," Qin Lan stated confidently.

"Xiao Lan, I'll help you. We must bring this Du Wei to justice," Lin Chen said indignantly.

Qin Lan shook her head, "No, it's too dangerous. The Du family is too powerful. I didn't want you to take me to the hospital yesterday because I was afraid those people would act desperately and attack me there."

Lin Chen smiled, "Don't forget what I said. I'm your man, and I'm definitely going to help you with this."

"Are you really not afraid of the Du family?" Qin Lan focused on Lin Chen.

Lin Chen burst into laughter, "I slapped Du Wei over a dozen times yesterday. Do you think I'm afraid of him?"

"You're too bold. Well, alright then, I've decided to accept you as my little sidekick," Qin Lan said with a smile.

At that moment, the sound of chaotic footsteps came from the doorway.

"Bang!" The door was forced open, and several police officers burst in.

```

"Xiao Lan, are you alright?" a plump police officer asked anxiously.

It turned out that last night, Qin Lan went out on patrol and hadn't returned all night.

Initially, her colleagues thought she had gone home, but in the morning they found her police car parked by the roadside. It was then that they deployed police forces to search for Qin Lan throughout the city, eventually finding her in this small motel.

Qin Lan blinked at Lin Chen, then said to the plump officer, "Chief Wang, I'm fine. I sprained my ankle chasing a criminal last night. This student helped me get here to rest for the night."

"So that's what happened! Xiao Lan, you've been under a lot of work stress lately. The department has decided to give you a long vacation for some rest," Chief Wang said with a smile.

"Great! I was just thinking about taking a break," Qin Lan replied with a twinkle in her eye and a smile.

Hearing how readily Qin Lan agreed, the plump officer was taken aback; he had been prepared to have a heart-to-heart with Qin Lan.

"That's best, that's best," Chief Wang said with an awkward smile.

After these officers left, Qin Lan took a deep breath of relief and said, "Lin Chen, take me to the airport. Yesterday, I found a bloodied glove near the scene, and I suspect it's related to this case. I need to go to Capital City to get it analyzed."

"Then I'll go with you," Lin Chen said, worried that the Du family would send an assassin after Qin Lan again.

"No need, I can go by myself. My friend in Capital City is a high-ranking police commissioner. The Du family wouldn't dare lay a hand on me in Capital City, don't worry," Qin Lan said with a smile.

"Hmm, but you must be careful. As soon as you're back in DY, tell me, and I'll come to pick you up," Lin Chen said.

"Okay," Qin Lan nodded.

The two immediately set out, and Lin Chen didn't relax until he had seen Qin Lan safely into the waiting room at the airport.

When Lin Chen returned to the base, he saw a large truck parked in the courtyard, with Xue Ying directing workers to move numerous medicinal cauldrons and pharmaceutical tools into the workshop.

Lin Chen walked into the workshop and was stunned to see rows of machinery neatly arranged throughout the space.

Xue Ying smiled and said, "Lin Chen, this is the production line custom-made just for you, according to your requirements."

"Sister Ying, you've really worked hard these past few days," Lin Chen said, scratching his head sheepishly.

"Why so formal with me? Come, see if this assembly line meets your needs," she said, turning on the machine and pouring a basin of herbs into it.

The assembly line machinery directly stripped the leaves from the herbs, leaving only the roots—in less than five minutes, they had processed the entire basin of herbs.

"Sister Ying, this is amazing! With this assembly line, we can start mass production," Lin Chen said excitedly.

Xue Ying nodded, "However, some herbs are quite rare, and they take too long to cultivate."

Lin Chen smiled, "Don't worry, you provide the seeds, and I'll handle the rest."

"You have a way?" Xue Ying asked, looking at Lin Chen with curiosity.

"Of course, I'll ensure supply is on time," Lin Chen said with a confident smile.

Thanks to the assembly line, Lin Chen only needed to mix and cook the ingredients according to the proportions, leaving the rest of the work to the laborers, which made the process very efficient.

In one morning, the first batch of fifty jars of weight loss tea, twenty jars of male vitality tea, and thirty jars of beauty cream were all prepared.

Xue Ying said excitedly, "The launch of our first batch of products will definitely make a splash across Huaxia."

Lin Chen nodded, confident in the effectiveness of his medicines.

Just then, Lin Chen's phone rang. It was Zhou Yufei calling, "Xiao Chen, today's my birthday. Can you come to my birthday dinner tonight?"

Lin Chen thought for a moment, then nodded and said, "Okay, I'll be there."
