Du Yan returned to his room and opened the book "Basic Alchemy Theory" given by Ning Zongwu.

Then, he was dumbfounded!

Oh my God, Ning Zongwu, you dead old man, yin me!

It's too pitiful, you call it "Basic Alchemy Theory", why is it not different from the textbook of the Eunuch Party Academy at all?

Every plant, animal, and medicine in it is new, and it has never been seen before. There are even some void energy bodies that need to be collected in some mines, and there are many unfamiliar gases, which also belong to basic alchemy?

I don't read much, don't lie to me!

Next, Du Yan saw a line of words in the gap of the book, which was clearly written, this book is an intermediate alchemy theory, because of a typographical error, it was printed as the cover of "Basic Alchemy Theory", please forgive me.

Damn, what a sinister old man.

Du Bian didn't have the time to worry about him at all, in order not to wash the toilet tomorrow, he had to work hard.

So, he quickly flipped through the "Intermediate Alchemy Theory", turning a page every six or seven seconds, and even then it took him two hours to finish the thick book.

It's a thousand pages, still half text, half pictures.

After two hours of reading, Du Bian extinguished the candle and went to sleep.

The Great Grandmaster always stared at Du Bian's house, and when he saw the candle extinguished, he immediately said proudly: "I only read it for an hour and gave up, at most two or three pages of content, my intermediate alchemy theory is really difficult, Du Bian, this kid will have a maximum of 30 points tomorrow, just teach him to be humble." ”

......

After a quick and cursory flip through it, Du Bian immediately lay down and went to sleep, quickly letting himself fall into a dream. He had to race against time, otherwise it would be too late even if he had a dream goldfinger.

After entering the dream, Du Bian's mind once again projected every page of the "Intermediate Alchemy Theory", like a slide.

The "Intermediate Alchemy Theory" written by Ning Zongwu is so difficult, because all the mutant species involved are unfamiliar mutant species, and many of them are even directly mysterious gases or energy bodies, all of which are extremely complex, abstract, and profound content.

For ordinary people, it is remarkable to be able to read a page in an hour.

However, the Devariant brain domain in the dream realm has developed more than ten times, so it only takes five or six minutes for a page of content to be memorized and even understood.

Read page by page, memorize.

An hour had passed, and he had read and memorized ten pages.

Ten hours passed, and he had read and memorized a hundred pages.

A day and a night passed, and Du Chang finished reading and memorizing two hundred and fifty pages.

At this time, the time in Du Chang's dream realm was many times more than that of reality, and the six-hour sleep world was about ten days in the dream world.

After four days and four nights, Du Bian finally memorized all of this thick book of "Intermediate Alchemy Theory".

It is useless to memorize it, but also to understand, integrate, and penetrate.

In the following time, Du Bian used to develop a tenfold brain domain to close his eyes and meditate, and deeply understand the theory of "Intermediate Alchemy" that had been memorized.

After a full day, Du Yan had the first level of understanding of this "Intermediate Alchemy Theory".

That is the intrinsic energy attribute of all species, and perhaps these species are ever-changing and take on various forms. But at the end of the day, there are more than a dozen energy attributes.

But this is only the most superficial understanding, even if it is a species with the same energy attribute, it can also show completely different characteristics, and the use of alchemy will also show completely different effects and reactions.

Next, Du Bian began to look for the second inner law in the "Intermediate Alchemy Theory", a deeper inner law.

It's very, very difficult, because the more than 500 species covered in this book are really varied, and it's hard to find other public laws other than energy attributes.

Just when Du Chang was puzzled, a diagram suddenly appeared in his mind: the periodic table.

And then......

It's all out of the way!

The mutated substances of this world, those mysterious and mysterious substances, are still not out of the periodic table.

Any kind of substance, whether it is energy, gas, or mutated species, can be found on the periodic table. It's just that it manifests itself in a different way, such as certain metals in a gaseous state, such as a special form in which elements and energy are mixed.

The invasion of special energy has caused some of the matter in this world to undergo abnormal changes.

But even if it is mutated, it is still not completely separated from the original material elements, nor is it separated from the atoms and molecules.

After mastering this law, after mastering the periodic table, the next learning, comprehension, and integration have become much easier.

Almost all reactions, all alchemy formulas and principles, can be demonstrated with chemical formulas.

This is the soul of alchemy, as long as you master this, almost all difficulties can find a way to solve.

Du Bian was inexplicably excited and admired, because this "Intermediate Alchemy Theory" was written by Ning Zongwu, he had never taken a chemistry class on the modern earth, and he didn't know what the periodic table was.

After finding the key to understanding this "Intermediate Alchemy Theory", Du Chang quickly comprehended the content of this book.

If it is changed to reality, it will take at least a year, and it will only need the guidance of famous teachers to be able to complete it.

However, in the dream world, his brain domain has developed ten times more than reality, and everything has become easier.

After ten days and ten nights in the dream realm, about two hundred and fifty hours, Du Bian finally mastered this "Intermediate Alchemy Theory" completely.

Outside, there was the crowing of a rooster.

Du Chang woke up.

......

After washing, Du Bian, Ning Zongwu, and the old servant had breakfast together.

"Du Bian, you read the book for less than an hour last night, and then you put out the candle and went to sleep?" Ning Zongwu asked, his words revealing smugness: "One hour, at most, is to understand two pages, which is remarkable." ”

Du Bian said: "Master Ning, you are yin against me." The book had "Basic Alchemy Theory" written on the skin, but the content inside was "Intermediate Alchemy Theory", and the Eunuch Academy had not taught a word at all. ”

Ning Zongwu said: "But in my eyes, he is the "Basic Alchemy Theory", and I clearly told you that a lot of the content of today's exam will be in this book." You said that I have mastered everything, and the exam will be the exam, and all this is what you promised. ”

Ning Zongwu, the old child, looked at Du Yan with a smug face, a picture that I know is shameless, but you are helpless.

"In this way, I will give you a chance. Ning Zongwu said: "You admit defeat now, and then express to me that you will no longer be proud and complacent in the future, and you will definitely listen to me seriously, and I will halve the punishment." You don't have to take the exam, there are a total of eight toilets in the Lotus Temple, and you can wash four of them. ”

The Great Grandmaster's conscience found that he should not be so ruthless in his students.

This is the legendary surrender losing half?

However, Du Bian didn't appreciate it and said: "No need, I still insist on the exam." ”

The Grand Master said: "Are you sure? If you don't score 90 points in the exam, you will have to wash eight toilets, don't blame me for being ruthless when the time comes." You haven't studied the Intermediate Alchemy Theory, and it's remarkable that you can read four or five pages in just one night. You are very good at being able to score 30 points in this exam, because these 30 points are the "Basic Alchemy Theory" that you have studied. ”

Then, Ning Zongwu said with self-satisfaction: "It takes a long, long time to read and recite this "Intermediate Alchemy Theory", let alone understand it deeply, there are two layers of internal laws in it, which are very profound, if you don't master the laws in it, you can't really be proficient in alchemy, even if you memorize this "Intermediate Alchemy Theory" ten times, it's useless." ”

Du Bian discovered that this great master not only likes to pit his students, but also likes to show off.

"Willing to lose, I'm sure. Du said: "I insisted on taking the exam, and if I didn't score 90 points, I would go to wash eight toilets." ”

"Hmph, I don't shed tears when I don't see the coffin. Ning Zongwu said: "Come on, prepare buckets, brushes, brooms, and let Du Bian go to wash the latrine as soon as the exam is over, and wash all the eight latrines in the whole temple clean, and if one is dirty, let him sit on it and eat." ”

"Yes!"

The princess left, so the monks of the Lotus Temple came back, and they brought buckets, brushes, brooms, linen and other tools for washing the latrines.

Then, Ning Zongwu and Du Bian came to the highest attic of the Lotus Temple.

Du Bian sat in a position, set up the pen and paper, and prepared for the exam.

Ning Zongwu said: "I hope that after this exam, you can guard against arrogance and rashness, and be low-key and humble." ”

Then, he placed the thick eight test papers in front of Du Bian, took out an hourglass and slammed it upside down, and the sand began to pour down.

"The exam will start in one hour!"

......

Du Bian opened the test paper of the "Alchemy Theory Exam", and then gasped.

He knew it would be hard, but he didn't expect it to be so hard!

It can be said that the content that belongs to the Eunuch Academy is really only thirty points, and the remaining seventy points are all from the "Intermediate Alchemy Theory".

Moreover, even if you memorize all the "Intermediate Alchemy Theory", you can only score 80 points.

The last twenty points need to be thoroughly comprehended, the inner essence of alchemy needs to be thoroughly mastered, and the deep laws between countless species need to be found, that is, the chemical content of the modern earth.

The difficulty of this exam is unimaginable in the Eunuch Academy, or it can be said that this exam can score 30 points, then the Eunuch Academy graduation examination on the basic theory of alchemy can get a full score of 100%.

It's all about the difference in difficulty between the Olympiad and the baccalaureate.

Even if Du Bian had mastered the "Basic Alchemy Theory" and the "Intermediate Alchemy Theory", it was still very laborious to answer. Each question requires a while of thinking before you can find an answer.

The two-hour exam time was set, and it took Du Chang an hour and a half to complete the answer.

Then I checked it twice and made sure it was completely correct.

This time, the exam is really not as easy as before. In the previous exam in front of Bai Chuan, Du Bian was completely effortless, and for the entrance examination of the great grandmaster, he knew the correct answer in advance.

And this time in the exam, it really depends on Du Bian's own ability.

He didn't even turn in the papers in advance, but checked them over and over again. This time it should still be a full score of 100, which is extremely brutal.

"It's time!"

When the sand in the hourglass ran out, Ning Zongwu got up and said, "Stop answering the question, get ready, and go wash the toilet." ”

Then, he stepped forward and took Du Bian's answer to the question for correction.

The next minute, his eyes widened, revealing the gaze of a ghost, and his throat seemed to be choked instantly, as if he was choked by the devil.
