Equivalent exchange .... Song Qing's mind was like a lightning bolt, and his soul seemed to have been hit by something.

This sense of impact is like a hand-me-down poem for a reader.

Equivalent exchange is the unchanging principle of alchemy!

"Yes, that's right, that's it...."Song Qing whispered to himself.

Whenever he succeeds in refining something, the raw materials disappear or are transformed into something else.

This phenomenon has always existed, but few people will notice it. Or I noticed it, but I didn't think too much, I didn't think about it so deeply.

"When the teacher taught us alchemy, he once said that the essence of alchemy is not "change", but transformation!"

"Equivalent exchange, that's what it meant...."

The outline-like sentence made this alchemy fanatic shudder.

After calming down his excitement, Song Qing began to think about the meaning of the words "Edward Elric".

Is it a name?

How can there be such a strange name.

Is it a code, or is it some kind of code word in the realm of alchemy?

I couldn't figure it out, and I was itchy for a while.

Song Qing took a deep breath, stabilized his emotions, and couldn't wait to turn to the next page, reading the distorted and ugly font professionally and patiently.

The first sentence of the opening sentence is: Enter the world of alchemy!

Is this teaching people to step into the realm of alchemy?

What arrogance! Song Qingxin said.

Alchemy has always been taught by word and deed, word of mouth, and those who are gifted and intelligent can get started in a year and a half, and those who are gifted and dull will achieve nothing in thirty or fifty years.

Si Tianjian still does not have a set of serious textbooks.

However, the sentence in the opening preface gave Song Qing enough patience.

"Section 1: Changes and properties of matter, there are many invisible examples in nature that constitute matter, and there are many interactions between matter, and there are constant changes..."

"I classify this change as: chemical change and physical change ...."

Song Qing looked at it and fell into deep thought.

What is chemistry.

What is an atom.

What am I looking at.

Why do I know every word, but when they are combined, I can't understand them?

The scriptures of the saints still have a collection of notes, why come to you, there is nothing?!

However, Song Qing did not find nothing, he was keenly aware that this was a unique book in the world.

It expounds the world as it is, and points out the most essential structure of all things in heaven and earth.

Song Qing's body trembled slightly, and for a moment, he wanted to tear up this book, this is a mystery that only gods can know, and mortals should not snoop on it.

But deep down, there is another force supporting him, which is the most primitive human desire for knowledge.

There was silence in the alchemy room.

The white-clothed people looked at each other, not daring to make a noise to disturb, deeply worried about Senior Brother Song Qing's unpredictable face.

"Senior brother is thinking about some unacceptable alchemy again. ”

"Yes, last year he tried to make a tree from the cat's flesh so that he could grow it back after cutting off the head, but he was imprisoned by the prison teacher for a month. ”

Song Qing was immersed in his own world, scared and excited at the same time, looking at it, his eyes lit up violently, because he saw a detailed explanation of the alchemy on how to refine tax silver.

Step 1: The first choice is to filter the brine to purify the sodium chloride (refined salt).

Step 2: Evaporate the brine, precipitate the crystals, and melt them at a high temperature of 800 degrees Celsius.

Step 3: Attention: This step is the key to refining tax silver, and success or failure is here.

Song Qing and the two sides let go, and finally, they were about to solve the problem that had plagued him and his junior disciples for a long time.

This is really a divine book.

Song Qing found that he had reached the end of the page, his saliva dipped in his fingertips, and he couldn't wait to turn to the next page.

A blank slate!

Song Qing: "???"

Without?!

Not to mention it?

What exactly is the third step, why is it not recorded, who wrote the book, this kind of writing out of chapter is a thousand cuts.

Song Qing spurted out a mouthful of old blood.

Song Qing opened his mouth, forgot something, and said in a deep voice: "Who sent this book?"

"Didn't pay attention. ”

"I didn't listen. ”

"Forgot. ”

The answers of the juniors and disciples were unusually true.

Song Qing immediately went downstairs, found the disciple who had received Wang Zhutou before, and asked in detail about the incident.

It's an exchange .... After Song Qing's analysis, he came to such a conclusion.

"Senior brother, what's wrong with you. The white-clothed disciples chased downstairs.

"What's wrong with this book?"

Song Qing's face was incomparably serious, sweeping everyone's faces, "Senior brothers, listen to me." This is an opportunity for Si Tianjian to rise rapidly. It is a once-in-a-lifetime opportunity, and alchemy may usher in unprecedented glory. ”

.....

Sheep Pavilion.

Two carriages drove slowly on the official road, and they sat the two great Confucians who had just finished spitting fragrant mouths.

Xu Xinnian and a group of classmates rode horses and fell behind the carriage.

"I shouldn't have told the truth. Xu Xinnian was a little remorseful.

The two Confucians were spitting quarrelsomely, and they were about to fight, Xu Xinnian said bluntly: Actually, the teacher and Mr. Mu Bai are just to get a hand-me-down poem.

The scene used to be awkward.

Although he stopped the two great Confucians from fighting, Xu Xinnian also realized that it was wrong to tell the truth.

"Mother is right, I have never been able to speak, I have to change!" Xu Xinnian introspected for the Nth time in his life.

He stretched out his hand into his arms and touched the fast and warm jade pendant, Xu Xinnian happily looked into the distance, and was happy, when a galloping figure appeared in his sight.

Oh, the silhouette of the figure came into view, it was his father Xu Pingzhi.

Xu Xinnian was stunned, grabbed the horse's belly, and swept the carriage to meet him.

"Dad, why are you here...."After speaking, Xu Xinnian's heart sank, and his father's face made him realize that something was wrong, even though he didn't know anything about it.

Xu Pingzhi told Xu New Year as quickly as possible.

Zhou Shilang's son-in-law molested his sister on the street..... I almost trampled the horse to death.... The eldest brother was escorted to the criminal department..... Xu Xinnian's brain was hot, and his blood was surging.

"Nian'er, your eldest brother's life and death depend on you. ”

"Dad, don't worry. Xu Xinnian's many thoughts flashed, and he soon had an idea, turned the horse's head, forced the carriage to stop, and said in a loud voice: "Teacher, Mr. Mu Bai, I have something to ask for the resignation." ”

The curtain opened, and Zhang Shen and Li Mubai poked their heads out, "What's the matter?"

"My brother is in trouble, please ask the teacher and Mr. Mu Bai to come to the rescue. Xu Xinnian retold what his father had told him.

Zhang Shen stared at him and said in a deep voice: "Is it the genius who wrote "Mo Chou has no knowers on the road ahead, and no one in the world knows you"?"

His voice was serious, as if it were important.

"Exactly!" Xu Xinnian nodded.

Zhang Shen was just about to speak, but Li Mubai, who was in the carriage on the side, cut off: "Say goodbye, leave your brother's affairs to me, you and your teacher will go back to the academy first." ”

"Hmph!" Zhang Shen snorted coldly: "Idle people, wait, don't be too troublesome." I'll take care of my students' business. ”

Xu Pingzhi was overjoyed, he didn't expect his son's face to be so big.

"Teacher, Mr. Mu Bai, my brother has been taken to the Criminal Department, please go quickly, I'm afraid of a change." Xu Xinnian said urgently.

Don't argue at this time.

PS: First, the stargazing building in the previous chapter was written incorrectly, it was the stargazing building, which has been changed.

Second, in the chapter of the Sheep Pavilion, the poem Don't Dong Da is a seven-word quatrain, with only two couplets. Seven words are one of the seven laws, but the seven laws are quadruple. The previous one will not be changed, and a patch will be made here.

Third, thank you to the leader of the big guy "Poetry Repair" for rewarding.
