Chapter 31

Key points?

Song Qing's brain is running at a high speed. Combined with her previous experiences of failure and her success this time, this paper makes an analysis.

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

What's the difference between this lightning strike and last one?

A few faint arcs flashed in his heart. Song Qing was shocked and said excitedly, "I understand. I understand."

"Xu Ningyan, you are a great alchemist."

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

No, I only know that your mind has gradually changed... Xu Qi'an smiles but doesn't speak.

"What's the point? Elder martial brother song, what do you know? "

"Elder martial brother song, oh, don't play tricks. Tell me quickly. This alchemy is becoming a demon for me."

The alchemists in White asked anxiously.

Looking around, the younger martial brothers of Song said, "it's the intensity of the thunder."

With that, he looked at Xu Qi'an with the eyes of verification.

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 v.

Voltage?!

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

Instinctively, he thought it was a great knowledge point, as profound as the essence of everything in the blue book.

A white alchemist stepped forward and bowed to Xu Qian: "please make it clear, what is voltage?"

"Ask us." Other alchemists in white arched their hands and said in unison.

Chu Tsai Wei, who was standing on one side, was envious. She liked the feeling of being a teacher and teaching an apprentice. It's a pity that she's just a feng shui master, and she's not qualified to teach apprentices.

Voltage, also known as potential difference or potential difference, is a physical quantity to measure the energy difference of unit charge in the 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 is the same as water, it will flow towards the low point."

Xu Qi'an raised the teacup and poured the water down. "It's OK for anyone to pour the cup, but if it's a waterfall, people will be broken by the impact of the water and even lose their lives. It's the same with electricity, which I call voltage. "

He used this easy to understand example to explain voltage.

The white clothes of Si Tian Jian frowned and lost in 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 cheered up: "so, on rainy days, thunder and lightning will hit the trees, but also because the trees are at a low point? The same goes for hitting people. In addition, if it's just a weak current, we will feel paralyzed at most. If we are bombarded by thunder, we will die. "

"The truth is that the voltage of Tianlei is so strong that it is beyond the limit of ordinary people, just like a waterfall. And the weak current is a glass of water, can withstand

Hearing Song Qing's words, the alchemists in white were suddenly enlightened. They were excited to obtain the profound meaning of truth, and turned their eyes to Xu Qi'an.

Well, is that the principle? Is it not the conductivity of rain that trees are struck by lightning? My middle school teacher didn't make it clear... Xu Qi'an himself was not sure, with a smile on his face: "a child can teach."

"This is also written on the alchemy book?" Asked a young man in white, his face full of curiosity.

"Yes, I've only read that alchemy book; I've studied it. I asked someone to send the contents of the notes to the sky warden, but they are just a drop in the ocean. " After a pause, Xu Qi'an said in a deep voice:

"that ancient book of alchemy not only records knowledge, but also has many unheard of alchemy."

Unheard of alchemy... On the spot, everyone breathed heavily.

Seven alchemists decided to share the secret script with Bai Xu

WOW!

Nearly twenty alchemists were excited on the spot.

"The blue book I gave to Si Tianjian is a gift of thanks for saving me. It tells you to improve the alchemy of fake silver refining and the knowledge I just taught you. It's not free." Xu Qi'an said: "of course, it also includes the following alchemy secrets."

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

Song Qing nodded and agreed with Xu Ningyan, then asked on behalf of the younger martial brothers:

"how much silver do you want?"

"Vulgar!" Xu Qi'an said in a deep voice: "alchemy can not be measured by silver."

No money is the most expensive... He added silently in his heart.....

Changle County Government, pianting.

Xu Lingyue is holding her sleeping younger sister in her arms, holding her handkerchief and sobbing.

looked at the little beauty with Kwai pear, the fast men's hearts were broken. I didn't expect that Xu Ningyan had such a beautiful sister.

Even Constable Wang, who has been to Jiaofang, is amazed by the little beauty.

some of the atmosphere of the Kwai Ting hall is depressed, and the faces of the fast men are ugly.

Constable Wang poured a cup of tea and put it in front of Xu Lingyue. The little beauty cried for a long time, but her tears never stopped. The woman was really made of water.

"Don't worry, Miss Xu. You will find a way to save Ning Yan."

other quick hands have been talking about comfort and scolding Kwai Kok.

's brother and his colleagues are very good. Xu Lingyue is somewhat surprised. Kwai's angry look is not like making fake.

"As if her head was a surprise," she said

Respect? Xu Lingyue was stunned and choked for a moment. She said in a soft voice, "Constable Wang, can you tell me something about my elder brother?"

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

"If you don't do it, you'll have a conscience. As for those rich businessmen, it's not natural for them to make money from them."

"But your elder brother doesn't, he never blackmail, whether he's a civilian or a rich businessman. A while ago, considering that the Xu family was in great trouble, I decided to take him to get some money... "Constable Wang said here, looking very strange, embarrassed, ashamed and admired:

" he grinned and agreed. Afterwards, I gave him five pieces of silver, but he gave it back quietly. "

"If you want to say that he is sensible, don't you understand that when the water is clear, there is no fish. But he's not sensible, he's good at coming, he's good at getting along with everyone, and he's smooth. So he had an accident, and everyone was upset. "

Xu Lingyue listened crazily. The image of big brother in her mind has become tall, bright and great.

Since she was a child, she worshipped Xu new year, because everything is inferior, only reading high, because her mother always taught her that the second brother is the only reading seed of the Xu family and the pillar of the future.

This kind of worship mood reached its peak in autumn this year, after Xu's new year's examination.

But with the tax case, the whole family went to prison. When they were desperate, big brother opened up a way for the whole family.

Xu Lingyue turns her attention to big brother again and is a little curious about him.

Until today, she knows how reliable this big brother is, just as she rescued them from prison a month ago.

At that time, the feeling was certainly not as deep as this one.

Seeing the moment when the elder brother saves her sister, Xu Lingyue thinks that the image of the elder brother is equal to that of the second brother.

At this moment, I heard Constable Wang's feeling that a noble, principled and bottom line image arises spontaneously. It has surpassed the second elder brother that I have always admired.

At this time, the light and shadow at the entrance of Pian hall changed. Xu Pingzhi and his son finally rushed back to Changle County Yamen. When they saw their sister (daughter), they were relieved.

Xu Lingyue raised her head with tears streaming down her face and said in a sad voice, "Dad, you have to save my elder brother. If my elder brother can't come back, my daughter won't live."
