In the library.

Ling Luo was reading a book when she suddenly heard someone greet her.

She looked up from her book, saw Bai Ying, and nodded: "Hello."

He paused, then asked, "Is there something you need?"

Bai Ying shook her head: "No, Your Highness, you're busy."

He came to the library to look for books, and when he saw her there, he simply came over to greet her politely; he had no other intentions.

Ling Luo nodded: "Oh."

After saying that, she didn't exchange any pleasantries with Bai Ying or ask him if he wanted to sit down with her, and then went back to reading her book.

After spending a brief time together on the spaceship, Bai Ying felt that Ling Luo was a straightforward person.

He didn't care about it.

He was about to leave, but when he saw the books Ling Luo was holding and the books placed beside her, he suddenly stopped in his tracks.

These books are too difficult, and some are very obscure. Without a very in-depth understanding of pharmaceuticals, it would be impossible to comprehend them.

Actually, he had heard about Ling Luo going to the library to read books a few days ago.

He had heard that the books she read seemed to be mostly obscure or difficult content.

Because Ling Luo was very interested in the venom of the Green Vine Snake when he was on the spaceship, he wasn't too surprised when he heard this news.

But--

Ling Luo noticed his gaze and looked up from her book: "Is this the book you're looking for?"

Bai Ying looked at her and shook her head: "No."

Ling Luo didn't think much of it and simply replied, "Oh."

I went back to reading my own book.

When Bai Ying saw this, he wanted to ask her if she could understand it, but then he felt that it was Ling Luo's own business and he shouldn't ask, so he didn't ask and turned to find the book.

A few minutes later, he found the book he was looking for. Not wanting to disturb Ling Luo, he didn't sit with her but instead sat down at another table.

The day for the assessment on Beast Star is fast approaching.

After returning from the Beast Planet, the students on campus have to prepare for their professional exams again.

As a result, the number of students studying at the library has gradually increased in the past few days.

However, most people who came left around lunchtime.

Bai Ying was also about to leave when she saw Ling Luo still sitting there, showing no intention of leaving. She hesitated for a moment before walking over and asking, "Crown Princess, aren't you going to eat?"

Ling Luo shook her head: "I can just drink the nutrient solution."

"oh……"

Bai Ying didn't ask any more questions and turned to leave.

He didn't have any classes in the afternoon, so he came to the library again.

He arrived relatively early, and when he saw Ling Luo still reading, he was taken aback: "You... haven't left the library?"

Ling Luo: "Mm."

Bai Ying was stunned. Seeing that she seemed very engrossed, she didn't disturb her any longer and went about her own business.

And so, a few days passed.

During these past few days, Bai Ying saw Ling Luo every time she came to the library.

He also noticed that the books on Ling Luo's desk were different every day.

However, he never bothered her too much, and Ling Luo only responded with a few words when he greeted her, but never spoke to him on her own initiative.

So, even though they sat one in front of the other these past few days, they didn't talk to each other much.

Then one day, as he was flipping through a book, he suddenly heard Ling Luo's voice: "Are you developing a new drug?"

"No." Bai Ying didn't know when she had arrived. Hearing this, she explained, "This is an interest question assigned by the teacher. We are asked to write a complete prescription based on these medicinal plants given by the teacher."

Ling Luo nodded: "You have no ideas?"

"……yes."

This interest-based question is somewhat special because it is not aimed at first-year students, but at all pharmacy students across the university.

This shows that this interest-based question is quite difficult.

He was quite interested and wanted to give it a try.

However, after studying it for several days, he was still completely baffled.

"Have you been researching this for several days?"

"Four days."

Ling Luo looked at him: "Do you know the medicinal properties of these medicinal plants?"

Bai Ying didn't know why she asked that, but she still nodded in response: "I understand, because the medicinal plants given in the question are all quite common. However, I don't even know what this prescription is for, because these medicinal plants are only part of it, and there's another part that I need to reconstruct myself..."

This is equivalent to developing a new drug.

The difficulty is immense.

Ling Luo asked, "Based on the medicinal properties of these herbs, can't you guess at all what the prescription will be used for?"

Bai Ying had her own ideas, and upon hearing this, she said, "I think this prescription should be a formula for an antidote."

The medicinal plants mentioned in the question all have strong medicinal properties and contain toxins.

Some antidotes also use medicinal plants that are generally highly toxic, but in small quantities, which neutralize the toxicity when combined with other medicinal plants.

Ling Luo shook her head: "The general direction is wrong. It's not for detoxification; it should be for prolonging cell activity. In other words, it's actually a prescription for a longevity drug."

Bai Ying was stunned for a moment, and before she could speak, Ling Luo said calmly, "Wait a moment."

"……good."

Ling Luo turned and left. Bai Ying stared at her retreating figure, unable to react for a long time.

Two minutes later.

Ling Luo is back.

He handed Bai Ying two books: "Some of the contents of these two books should be helpful in solving your problems. You can take a look."

As soon as Bai Ying took the book, Ling Luo turned around and went back to her seat.

Bai Ying glanced at the titles of the two books in her hand and noticed that one of them was a comprehensive record of the functions and properties of some basic medicinal plants.

Such books are actually quite common.

But what makes this book different from others is that the author is quite interesting. He added the effects and reactions of different medicinal plants, different parts, and different dosages behind each medicinal plant.

Bai Ying found the medicinal plants mentioned in the question and actually discovered some knowledge he didn't know before.

Bai Ying was mesmerized.

He hadn't heard of the title of the other book.

It is mainly a comprehensive guide to poisonous plants.

Some of these plants are medicinal plants, and some are not.

However, when medicinal plants and ordinary plants are combined, they can be used to create medicines.

Bai Ying also loves reading.

I consider myself to be a well-read person.

But he hadn't actually read either of those books.

The more I looked at him, the more excited I became.

After watching for only a short while, Bai Ying already had some ideas about how to solve the problem.

He immediately put away the book, intending to go back to the school's laboratory to try it out.

Before leaving, seeing Ling Luo's retreating figure, he walked over and asked, "Do you already know which medicinal plants are missing from the question?"

Ling Luo nodded: "Mm."

These medicinal plants do not exist in the cultivation world.

Although she hadn't studied medicinal plants for long and hadn't prepared any medicines, there were some commonalities between medicinal plants and spiritual herbs.

The seven or eight medicinal plants mentioned in the question seem to be basic medicinal plants, but they can be used to prepare many kinds of medicines.

In reality, because the medicinal properties counterbalance each other, only one kind of medicine can ultimately be prepared, and that is—a longevity-extending medicine.

However, the medicinal plants they used were not very effective at prolonging life. If three of them were replaced with others, the effect would be more significant.
