key point
Song Qing's brain was running fast, and he analyzed it based on the experience of several previous failures and this success.
The previous steps have not changed, the real change should be the last step: lightning strike!
How is this lightning strike different from last time
A few slightly weak arcs flashed in his heart, and Song Qing was shocked and said excitedly: "I understand, I understand."
"Xu Ningyan, you are really an amazing alchemy genius."
"Although you haven't seen our failure before, you already knew it, right? You already knew the real reason for our failure."
No, I only know that your thoughts are gradually diverted, Xu Qi'an smiled without saying a word.
"What's the key? Brother Song, what do you understand?"
"Senior Brother Song, oh, don't give a shit, hurry up, this alchemy is about to become a demon in my heart."
The white-clothed alchemists asked anxiously.
Song Qing coughed, looked around at the juniors, and said solemnly, "It's the intensity of the lightning strike."
After he finished speaking, he looked at Xu Qi'an with a questioning look.
Xu Qi'an nodded with a smile, and said, "I named it voltage."
The voltage for refining sodium metal should be controlled at 6-15 volts.
Voltage? !
Song Qing was stunned. It was a word he had never heard before. He knew about electricity, but what was voltage
Instinctively, he felt that this was an amazing point of knowledge, as profound as the essence of everything written in that blue book.
An alchemist in white took a step forward and bowed to Xu Qi'an: "Please explain clearly, what is voltage?"
"Ask us." The other alchemists in white clasped their hands at the same time and said in unison.
Chu Caiwei, who was standing on the side, was envious. She liked the feeling of being a husband and teaching an apprentice the most. It's a pity that she is only a Feng Shui master and is not qualified to teach disciples.
Voltage, also known as potential difference or potential difference, is a physical quantity that measures the energy difference of a unit charge in an electrostatic field due to different potentials. Of course, you can't understand what I said. Xu Qi'an coughed and his face was serious:
"Electricity, like the flow of water, will flow toward the low point."
Xu Qi'an raised the teacup and poured the water inside, "It's fine for anyone to pour this cup on, but if it is a waterfall, people will be broken by the impact of the water, and even lose their lives. Electricity is also So, I call this phenomenon voltage."
He explains voltage with this easy-to-understand example.
The white-clothed members of the Sitian Supervisor frowned and fell into deep thought. They didn't understand Xu Qi'an's words very well.
Although they are alchemists and have the ability to manipulate lightning, it does not mean that they understand the nature of electricity.
Song Qing suddenly understood something, and said excitedly: "So, thunder and lightning will hit 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 will feel paralyzed at most. And if you are bombarded by thunder, you will die."
"The truth is that the voltage of Tianlei is so strong that it exceeds the limit of mortals, like a waterfall. And the weak current is a glass of water, which can be endured."
Hearing Song Qing's words, the white-clothed alchemists suddenly became enlightened. They were excited to have obtained the profound meaning of the truth, and turned to Xu Qi'an with the eyes of proof.
Um, is that the principle? Is it not the electrical conductivity of rain that causes trees to be struck by lightning? My middle school teacher didn't make it clear, Xu Qi'an wasn't sure either, with a smile on his face: "Ruzi can be taught."
"This is also written on that alchemy book?" a young man in white asked, his face full of curiosity.
"Yes, only I have read and studied the alchemy secret book. The contents of the notes I had sent to Si Tianjian were just a drop in the ocean." After a pause, Xu Qi'an said solemnly:
"That ancient alchemy book not only records knowledge, but also many unheard of alchemy techniques."
The unheard of alchemy was on the spot, and everyone was breathing heavily.
Xu Qi'an smiled and threw out a promise that made the white clothes boil: "I decided to share the alchemy secrets with Si Tianjian."
Whoa!
Nearly twenty alchemists were boiling on the spot, excited.
"The blue book I gave to Si Tianjian is a thank you gift for saving me. It instructs you to improve the alchemy of counterfeit silver refining, and I taught you about voltage just now. It is not free." Xu Qi'an said eloquently:
"Of course, it also includes the follow-up alchemy secrets."
"Never forget that the principle of alchemy is equal exchange!"
Song Qing nodded, agreeing with what Xu Ningyan said, and asked the question on behalf of the juniors:
"How much money do you want?"
"Vulgar!" Xu Qi'an said solemnly, "How can alchemy be measured by silver?"
Those who don't want money are the most expensive, he added silently in his heart
Changle County Government Office, side hall.
Xu Lingyue held her sleeping younger sister in her arms, pinched her handkerchief, and cried sobbing.
Looking at the little beauty with pear blossoms and rain, the Kuaishou of Kuaiban will be heartbroken. I didn't expect Xu Ningyan to have such a pretty and beautiful younger sister.
Even going to Jiaofang Siwang Caotou was amazed by the little beauty.
The atmosphere in the side hall was a little depressing, and the Kuaishou looked ugly and stunned.
Wang Zhaotou poured a cup of tea and placed it in front of Xu Lingyue. This little beauty cried and cried for a long time, but the tears didn't stop. The woman was really made of water.
"Miss Xu, don't worry, Lord Baihu will find a way to rescue Ning Yan."
The other Kuaishou spoke out to comfort and scolded Zhou Gongzi.
The relationship between the eldest brother and his colleagues is very good. Xu Lingyue is a little surprised, and the angry expressions of the Kuaishou do not seem to be fake.
As if seeing her surprise, Wang Zhaotou smiled: "Ning Yan is a person worthy of respect."
Respect? Xu Lingyue was stunned for a while, choked for a moment, and said in a soft voice, "Wang Zhaotou, can you tell me about my eldest brother?"
Wang Zhaotou was silent for a while, and he lowered his voice unconsciously: "Actually, for people like us, how can there be clean hands?"
"If you don't take action against ordinary people, you have a conscience. As for those rich businessmen, it's not justified to get oil and water from them."
"But your eldest brother won't, whether it is a commoner or a wealthy businessman, he never goes to blackmail. A while ago, considering that the Xu family was in great trouble, I decided to take him to make a fortune." Wang Zhaotou said here, his expression was very Strange, embarrassed, ashamed, and admired:
"He grinned and agreed. Afterwards, I distributed five coins to him, but he quietly returned it to others."
"Let's say he is sensible, don't you understand the truth that when the water is clear, there are no fish. But to say that he is ignorant, he is very knowledgeable, and he has a good relationship with everyone, and people are slick. So he went out. It's going to hurt everyone."
Xu Lingyue listened in awe, the image of the eldest brother in her mind became tall, bright and stalwart.
She has admired Xu New Year since she was a child, because the only thing that is inferior is reading, because her mother always instills in her that the second brother is the only seed of reading for the Xu family and the pillar of the future.
This kind of worship has reached its peak in the autumn of this year, after Xu New Year's examination.
But in the ensuing tax and silver case, when the whole family was imprisoned and desperate and helpless, the eldest brother opened up a way for the whole family to survive in the desperate situation.
Xu Lingyue turned her attention back to her eldest brother and became a little curious about him.
Until today, she didn't know how reliable this eldest brother was, just as she rescued the desperate women from prison a month ago.
At that time, the feeling was definitely not as profound as this time.
The moment she saw the eldest brother save her sister, Xu Lingyue felt that the image of the eldest brother was equal to that of the second brother.
At this moment, when I heard Wang Zhaotou's sigh, a high-spirited, principled and bottom-line image emerged spontaneously, rising layer by layer, surpassing the second brother whom he 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 the Changle County Office. They were relieved to see their sister (daughter) who was safe and sound.
Xu Lingyue raised her head, with tears streaming down her face, and said sadly, "Father, you have to save eldest brother. If eldest brother doesn't come back, his daughter will also die."
