Nightwatcher Chapter 31: This is not wool, this is equivalent exchange
The key point?
Song Qing’s brain is running fast, combining the previous experience of several failures and this success for analysis.
The previous steps have not changed. What really changed should be the last step: lightning strike!
How is this lightning strike different from the last time?
Several faint electric arcs flashed in his heart, Song Qing's body was shaken, and excitedly said: "I understand, I understand."
"Xu Ningyan, you are such an amazing alchemy genius."
"Although you haven't seen our failure before, you already know it in your heart, right, you already know the real reason for our failure."
No, I only know that your thoughts have gradually changed... Xu Qi'an smiled and said nothing.
"What's the key? Brother Song, what do you know?"
"Brother Song, don't betray you, just say it, this alchemy is about to become my demon."
The white-clothed alchemists asked anxiously.
Song Qing coughed, looked around the juniors, and said solemnly: "It's the intensity of the lightning strike."
finished speaking, he looked at Xu Qi'an with a verification gaze.
Xu Qi'an smiled and nodded, and said: "I named it voltage."
The voltage for refining sodium metal should be controlled at 6-15 volts.
Voltage? !
Song Qing was taken aback, and it was another word he had never heard before. He knew electricity, but what was the voltage?
instinctively, he thinks this is an amazing point of knowledge, as profound as the essence of everything written in that blue book.
A white-clothed alchemist took a step forward and bowed his hand to Xu Qi'an: "Please tell me, what is voltage?"
"Ask us." The other alchemists in white clasped their hands at the same time and said in unison.
, Chu Caiwei, who stood by, was envious. She liked the feeling of being a teacher and teaching apprentice best. It's a pity that she is just a Feng Shui master, not qualified to teach apprentices.
Voltage is also called potential difference or potential difference. It is a physical quantity that measures the energy difference of a unit charge in an electrostatic field due to different potentials... Of course, you don't understand all of what I said. Xu Qi'an coughed, his face serious:
"Electricity is the same as water flow. It will flow towards a low point."
Xu Qi'an raised the tea cup and poured out the water inside, “It’s okay to pour this cup on anyone, but if it’s a waterfall, if you are in it, you will be hit by the impact of the water and break your bones and even lose your life. The same is true for electricity, I call this phenomenon voltage."
He uses this easy-to-understand example to explain voltage.
The white-clothed men of Si Tianjian frowned and fell into thought. They did not understand Xu Qi'an well.
Although they are alchemists, they all have the ability to manipulate lightning, but this does not mean that they understand the nature of electricity.
Song Qing suddenly understood something, and exclaimed: "So, thunder and lightning strikes trees in rainy days, because the trees are at a low point? The same is true for hitting people. In addition, if it is only a weak current, we are most I feel numb, and if I am bombarded by the sky thunder, I will die."
"The truth is that the voltage of the sky thunder is so strong that it exceeds the limit that mortals can withstand, like a hanging waterfall. And a weak current is a cup of water, which can withstand it."
Hearing Song Qing's words, the white-clothed alchemists suddenly became excited, and they were excited to have obtained the truth and meaning, and cast their eyes on Xu Qi'an for verification.
um, is this the principle? Isn’t the reason why trees are struck by lightning not because of the conductivity of rainwater? My middle school teacher didn’t make it clear...Xu Qi’an was not sure about himself, with a smile on his face: "Russ can teach."
"Is this also written in that alchemy secret book?" A young man in white asked, his face full of curiosity.
"Yes, I have only read the alchemy cheats; I have studied it. The contents of the notes I sent to Si Tianjian are just a drop in the ocean." After a pause, Xu Qi'an said in a deep voice:
"The ancient alchemy book not only records knowledge, but also many unheard of alchemy."
Unheard of alchemy...on the spot, everyone's breathing became heavy.
Xu Qi'an smiled, and threw a promise that made the white clothes boil: "I decided to share the alchemy secrets with Si Tianjian."
Wow!
Nearly twenty alchemists boiled on the spot, excited.
"The blue book I gave to Si Tianjian is your thank you for saving me. It instructs you to improve the alchemy of counterfeit silver refining, and just taught you the knowledge of voltage. It is not free." Xu Qian said. And talk:
"Of course, it also includes the follow-up alchemy cheats."
"Never forget, the principle of alchemy is equivalent exchange!"
Song Qing nodded, agreeing with Xu Ningyan’s truth, and asked questions on behalf of the juniors:
"How much silver do you want?"
"vulgar!" Xu Qi'an said solemnly: "How can alchemy be measurable by silver."
The one that doesn't need money is the most expensive... He added silently in his heart.
.......
Changle County Office, Partial Hall.
Xu Lingyue held the sleeping young girl in her arms, squeezed her handkerchief, sobbed sobbing.
Looking at the little beauty with rain in Ewha, the quick hands of Kuaiban are heartbroken. I didn't expect Xu Ningyan to have such a pretty and beautiful sister.
even went to Jiaofang Siwang to catch his head and was surprised by the little beauty.
The atmosphere in the side hall is a bit depressed, and the quick hands have ugly faces, and they faint.
Wang caught his head and poured a cup of tea and placed it in front of Xu Lingyue. The little beauty cried for a long time, but the tears never stopped. The woman was really made of water.
"Miss Xu is not anxious, the adults of 100 households will find a way to rescue Ning Yan."
Other Kuaishou uttered comforting words and scolded Master Zhou.
Brother and his colleagues have a very good relationship... Xu Lingyue is a bit surprised, and the quick hands do not seem to be fake.
As if seeing her surprise, Wang Catchhead smiled: "Ning Yan is a person worthy of respect."
Respect? Xu Lingyue was stunned, choked, and whispered in a low voice: "Wang catches his head, can you tell me about my big brother."
The king caught his head and fell silent for a moment, and unconsciously lowered his voice: "In fact, for people like us, how can there be clean hands underneath?"
"If you don’t act against ordinary people, it’s even conscientious. As for those wealthy businessmen, it’s not a matter of course for those wealthy businessmen to get money from them."
"But your eldest brother doesn't know how, no matter whether he is a commoner or a wealthy businessman, he never blackmails him. A while ago, considering that the Xu family was in trouble, I decided to take him to make a fortune..." Wang Shu At this point, the head looks very strange, embarrassed, ashamed, and admired:
"He smiled and agreed. Afterwards, I gave him five coins~IndoMTL.com~ but he quietly returned it to others."
"If you say he is sensible, don’t you understand the truth that there are no fish when the water is clear. But if you say he is ignorant, and knows how to get things going, he has a good relationship with everyone, and he is slick. So something happened to him and everyone was uncomfortable."
Xu Lingyue listened obsessively, the image of her eldest brother in her mind became tall, bright and stalwart.
She has admired Xu New Year since she was a child, because everything is inferior, but she can only read high school, because her mother always instilled in her that her second brother is the only seed of the Xu family for reading and the pillar of the future.
This kind of adoration reached its peak in the autumn of this year.
But with the ensuing tax and silver case, the family went to jail, desperate and helpless, the eldest brother opened a way for the family in desperation.
Xu Lingyue turned her attention to her elder brother again, and became a little curious about him.
Until today, she didn't know how reliable this eldest brother was, just as she rescued desperate them from prison a month ago.
At that time, the feeling was definitely not as profound as this time.
The moment when he saw the eldest brother save his younger sister, Xu Lingyue felt that the image of the eldest brother was equal to the second brother.
At this moment, when I heard Wang Catou’s emotion, a high-spirited, principled and bottom-line image emerged spontaneously, level by level, and has surpassed the second brother who had always been worshipped.
At this time, the light and shadow at the entrance of the Pian Hall changed, and Xu Pingzhi and his son finally rushed back to the Changle County government office. When they saw their safe sister (daughter), the father and son were relieved.
Xu Lingyue raised her head, burst into tears, and said mournfully: "Father, you have to save your eldest brother. If your eldest brother can't come back, your daughter won't live."
