Qian Renxue hurriedly closed the entire book again, calmed down her mood, and after confirming that the title of the book was Principles of Optics, she turned to the table of contents page again.

In her concept, light should be warm and full of vitality, but also hot and full of destructive power. The greatest light is the light of the sun. As the inheritor of the Angel God, once it passes through the first After seven tests, she will be able to pull out the Holy Angel Sword and burn all opponents with the help of the true fire of the sun.

Light and heat should be one in her eyes. As for the affinity with light, as the inheritor of the Angel Divine Test, she is not inferior to anyone.

With such stubbornness, Qian Renxue opened the book again.

Dugu Bo almost didn't laugh out loud when he saw this scene. If he didn't have dentures in his mouth, he would probably have laughed out loud with his dentures.

On the principles of optics, this book took him a long time to chew slowly before he could finish it. How dare Qian Renxue read such a book in the first place.

If you want to truly understand this book, you must read at least six books including "Elementary Mathematics", "Advanced Mathematics", "Elementary Physics", "Linear Algebra", "Mathematical Statistics" and "Electromagnetism". Only then can you be qualified to study "Optical Principles". This girl doesn't think that because she has the inheritance of an angel god, she is qualified to skip these prerequisite subjects, right?

Dugu Bo looked at Qian Renxue, whose face turned darker and darker the more he looked at it, with a strange look on his face. He didn't know what to say for a moment.

Even the deans of each college like them have to study the prerequisite subjects before they want to learn the knowledge of other colleges, especially various works on mathematics. Without these prerequisites, there is no way. Understand these ghost-like descriptions.

Chapter 4 Geometric Theory of Optical Imaging

After reading the catalog of optical principles that was like a heavenly book, Qian Renxue fell into deep self-doubt.

Do I know nothing about optics?

Or is it that this book is not actually about optics, but it just has the wrong cover?

Qian Renxue really wants to say it must be the latter, but both the preface and the table of contents clearly tell Qian Renxue that yes, this book is about the principles of optics, but you know nothing about real optics. .

In front of Qian Renxue's eyes appeared Zeng Yixin's big face that needed a beating. His smile seemed to be an invisible mockery, making Qian Renxue tighten her fists.

...

Dugu Bo said: "Don't mention it yet, your theory is really interesting. Wait a minute, I will write down your explanation angle, and then I will take some time to think about it more."

Dugu Bo took out his notebook from his treasure bag and wrote down the theory just put forward by the turtle. Looking at the densely packed ghost symbols in Dugu Bo's book, the turtle almost fainted.

"What are all the monsters and ghosts written in your notebook? Why can't I understand any of them?"

Dugu Bo saw that his old enemy could no longer understand the notes he had taken, and he said proudly: "Greyfish, times have changed, and you can't keep up with the times if you don't study more."

Looking at Dugu Bo's stinking fart, his teeth were itching with the fumes, but when he thought about the other party's ability to separate out the effects of various components contained in various herbs and form new components after combining them, he still pulled himself away. The old face said: "Hurry up, tell me how you did the scientific analysis of Nalaoshizi. This thing is much easier and more accurate than explaining it with Yin Yang and Five Elements."

Dugu Bo glanced at the agouti who had pricked up his ears and listened carefully, and Qian Renxue, who was hiding aside but was eager for knowledge, and simply said: "These things all require pre-disciplines, and there is no pre-discipline understanding." It’s not the way I calculate it, it’s a… system.”

"The sect master plans to discuss with your Wuhun Palace about publishing new books in a while. But as for the ugly words, these books are not those related to people's livelihood. Except for the Agricultural College that is branched off from the Pharmacy College, it will publish a book about planting. Except for books on soil and crop care that may have good sales, the rest of the books probably have little sales.”

The agouti waved his hand and said, "What's the matter? If you want to make money, Bibi Dong makes money, and if you lose money, Bibi Dong loses money. You haven't told me why I can't understand the ghost symbols on your notebook."

Dugubo explained: "This requires a foundation in mathematics. Without a foundation in mathematics, you will not be able to learn it, regardless of physics or chemical biology. The books to be distributed this time include elementary mathematics and advanced mathematics, etc. Only after you have read these two books thoroughly can you be qualified to use my method of analyzing medicines."

Qian Renxue's eyes lit up as she eavesdropped from the side. She knew that optics belonged to a branch of physics. It seemed that she couldn't understand the principles of optics. The problem lay in elementary mathematics and advanced mathematics.

Dugu Bo raised his head and looked at the soul clock in the laboratory and said: "Come on, follow me to the imperial kitchen. That's the only thing that's wrong about working in Tiandou City. You have to grab a meal and see if anyone is there." poison."

The agouti rolled his eyes: "It's the same as your mental power covering the entire Tiandou Palace. You just want to eat something on the way."

When Dugu Bo heard this, he was immediately unhappy: "What do you mean by the way? Fengzhi asked me to be a security guard for the Tiandou royal family. I have to take care of food and shelter, right?"

The agouti didn't want to expose Dugu Bo, but nodded perfunctorily and said: "Yes, yes, you're right, I'm greedy. Let's go. I heard that the wontons made by the chef in Tiandou's imperial kitchen are excellent. Let’s go and have a taste.”

The two walked out of the laboratory arm in arm, leaving Qian Renxue alone looking at the optical principles in her hands in a daze.

"Prerequisite subjects..."

Qian Renxue murmured, and then pulled out a book from Dugu Bo's collection of books with four big characters printed on it.

"Elementary Mathematics."

When the agouti and Dugu Bo came back from the imperial dining room beautifully, they saw Qian Renxue leaning on a small table and reading elementary mathematics carefully. From time to time, she would write and draw on a piece of papyrus, as if she was calculating something.

The agouti was as honest as an apprentice, watching Dugu Bo's chemical experiments seriously.

...

"Your Majesty, His Highness the Crown Prince has been in Dugu Mian's laboratory all day."

Emperor Xueye waved his hand with a smile: "Don't worry about him. If Qinghe can make good friends with Dugu Mian, it will be a good thing."

...

"Your Majesty, His Royal Highness the Crown Prince..."

Xue Ye became a little impatient and said, "Didn't I say it before? Qinghe is a sensible person. Staying with Dugu Mianxia for a few more days will only bring benefits to me, Tiandou, but no harm."

"But Your Majesty, His Royal Highness is obsessed with mathematics and has not eaten for three days."

The servant said tremblingly.
