Dafeng Night Watchman

Chapter 31: Chapter 31 This is not fleecing, this is equal exchange



The key point?

Song Qing's brain was working fast, combining the experience of several previous failures and this success, and analyzing it.

The previous steps have not changed, and the real change should be the last step: lightning strike!

What is the difference between this lightning strike and the last time?

A few slightly weak arcs flashed in his mind, and Song Qing's body shook, and he said excitedly: "I understand, I understand."

"Xu Ningyan, you are really an amazing alchemy genius."

"Although you haven't seen our previous failures, you already know it in your heart, right? You already know the real reason for our failure."

No, I only know that your thinking has gradually become Di... Xu Qian'an smiled and said nothing.

"What is the key? Senior Brother Song, what do you understand?"

"Senior Brother Song, oh, don't keep me in suspense, tell me quickly, this alchemy is almost becoming my inner demon."

The white-clothed alchemists asked anxiously.

Song Qing coughed, looked around at his fellow apprentices, and said in a deep voice: "It is the intensity of the lightning strike."

After saying that, he looked at Xu Qi'an with a look of verification.

Xu Qi'an smiled and nodded, and said: "I named it voltage."

The voltage for refining metallic sodium should be controlled at 6-15 volts.

Voltage?!

Song Qing was stunned. It was another word he had never heard of. He knew about electricity, but what was voltage?

Instinctively, he felt that this was an amazing knowledge point, as profound as the essence of everything written in the blue book.

A white-clothed alchemist stepped forward and bowed to Xu Qi'an: "Please tell me, what is voltage?"

"Please teach us." The other white-clothed alchemists bowed at the same time and said in unison.

Chu Caiwei, who was standing aside, was envious. She liked the feeling of being a teacher and teaching apprentices the most. It was a pity that she was just a Feng Shui master and was not qualified to teach apprentices.

Voltage, also known as potential difference or electric potential difference, is a physical quantity that measures the energy difference generated by the different electric potentials of a unit charge in an electrostatic field... Of course, you all don't understand what I said. Xu Qian'an coughed and looked serious:

"Electricity is the same as water flow. It will flow to the lower point."

Xu Qian'an raised the teacup and poured the water in it down, "It doesn't matter who this cup falls on, but if it is a waterfall, people will be broken bones or even lose their lives by the impact of the water. The same is true for electricity. I call this phenomenon voltage."

He used this easy-to-understand example to explain voltage.

The white-clothed people of the Sitianjian frowned and fell into deep thought. They did not understand Xu Qian'an's words very well.

Although they are alchemists and have the ability to manipulate lightning, this does not mean that they understand the nature of electricity.

Song Qing suddenly understood something and said excitedly: "So, lightning strikes trees in rainy days because the trees are at a low point? The same is true for people. In addition, if it is just a weak current, we will feel paralyzed at most, but if we are struck by thunder, we will die."

"The truth is that the voltage of thunder is so strong that it exceeds the limit of mortals, like a waterfall. And the weak current is like a cup of water, which can be endured."

Hearing Song Qing's words, the white-clothed alchemists suddenly became enlightened, and they were excited as if they had obtained the truth, and looked at Xu Qian'an with a look of verification.

Uh, is this the principle? Isn't the principle of trees being struck by lightning the conductivity of rainwater? My high school teacher didn't explain it clearly... Xu Qian'an himself was not sure, and smiled: "Ruzi is teachable."

"Is this also written in that alchemy secret book?" A young man in white asked, his face full of curiosity.

"Yes, I am the only one who has read and studied that alchemy secret book. The contents of the notes I sent to the Imperial Observatory are just a drop in the ocean." After a pause, Xu Qi'an said in a deep voice:

"That ancient alchemy book not only records knowledge, but also contains many unheard-of alchemy techniques."

Unheard-of alchemy techniques... On the spot, everyone's breathing became heavier.

Xu Qi'an smiled and made a promise that made the white-clothed people excited: "I decided to share the alchemy secret book with the Imperial Observatory."

Wow!

Nearly twenty alchemists were excited on the spot.

"The blue book I gave to the Imperial Astronomical Bureau is a thank you gift for saving me. I taught you how to perfect the alchemy of making fake silver, and I taught you the knowledge of voltage just now. It is not free." Xu Qi'an talked freely:

"Of course, it also includes the subsequent alchemy secrets."

"Never forget that the principle of alchemy is equal exchange!"

Song Qing nodded, agreeing with what Xu Ningyan said, and asked on behalf of his junior

brothers:

"How much silver do you want?"

"Vulgar!" Xu Qi'an said in a deep voice: "How can alchemy be measured by silver?"

The most expensive thing is the one that doesn't cost money... He added silently in his heart.

....

Changle County Government Office, Side Hall.

Xu Lingyue held her sleeping little sister in her arms, holding her handkerchief, sobbing.

Looking at the little beauty with pear blossoms in the rain, the quick hands of the fast class were heartbroken. I didn't expect Xu Ningyan to have such a pretty and beautiful sister. Even Wang, the captain who had been to the Jiaofangsi, was amazed by the little beauty. The atmosphere in the side hall was a bit depressing, and the quick hands looked ugly and

wilted.

Captain Wang poured a cup of tea and placed it in front of Xu Lingyue. The little beauty cried for a long time, and her tears never stopped. Women are really made of water.

"Miss Xu, don't worry. The captain will find a way to rescue Ning Yan."

Other quick hands comforted and scolded Mr. Zhou.

The relationship between the eldest brother and his colleagues is very good... Xu Lingyue was

a little surprised, and the angry expressions of the quick hands did not seem to be fake.

As if seeing her surprise, Captain Wang smiled and said, "Ning Yan is a respectable person."

Respect? Xu Lingyue was stunned for a moment, sobbed a little, and said softly: "Captain Wang, can you tell me about my elder brother?"

Captain Wang was silent for a moment, and unconsciously lowered his voice: "In fact, people like us, how can we have clean hands?"

"Not taking action against ordinary people is considered a conscience, as for those wealthy businessmen, it is not natural to take advantage of them."

"But your elder brother will not, whether he is a commoner or a wealthy businessman, he

never blackmails. A while ago, considering that the Xu family suffered a great disaster, I decided to help him make a fortune..." Captain Wang said here, his expression was very strange, embarrassed, ashamed, and admiring:

"He agreed with a smile, and I gave him five cents of silver afterwards, but he quietly returned it to others later."

"If you say he is sensible, don't you understand the principle that if the water is too clear, there will be no fish? But if you say he is not sensible, he is very good at dealing with things, and he has a good relationship with everyone. He is very slippery. So when he gets into trouble, everyone feels bad."n/ô/vel/b//in dot c//om

Xu Lingyue listened infatuatedly, and the image of her eldest brother in her mind became tall,

bright and majestic.

She has admired Xu Xinnian since she was a child, because everything is inferior except reading, because her mother always instilled in her that her second brother is the only seed of reading in the Xu family and the pillar of the future.

This admiration reached its peak when Xu Xinnian passed the imperial examination in the

autumn of this year.

But the tax case that followed, the whole family was imprisoned, and when they were

desperate and helpless, the eldest brother opened up a way out for the whole family in

despair.

Xu Lingyue shifted her attention to the eldest brother again and became a little curious about

him.

It was not until today that she knew how reliable this eldest brother was, just as he rescued them from the desperate prison a month ago.

At that time, the feeling was definitely not as profound as this time.

The moment she saw her elder brother saving her younger sister, Xu Lingyue thought that her elder brother was equal to her second brother.

At this moment, hearing the sigh of Captain Wang, an image of a noble character, principled

and bottom line emerged spontaneously, rising layer by layer, surpassing the second brother she had always admired.

At this time, the light and shadow at the entrance of the side hall changed, and Xu Pingzhi and

his son finally rushed back to Changle County Government. Seeing their sister (daughter) safe and sound, the father and son were relieved.

Xu Lingyue raised her head, tears streaming down her face, and said in a sad voice: "Dad, you have to save my elder brother. If he doesn't come back, my daughter will not live either."
