key point?

Song Qing's brain was running fast, and she 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?

Several weak electric arcs flashed in his heart, Song Qing's body shook, and he said excitedly: I understand, I understand.

Xu Ningyan, you are truly an amazing alchemy genius.

Although you haven't seen our failure before, you already knew it in your heart, right? You already knew 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 understand?

Senior Brother Song, hey, don't be a fool, tell me quickly, this alchemy is almost becoming my demon.

The alchemists in white asked anxiously.

Song Qing coughed, looked around at the juniors, and said in a deep voice, It's the intensity of the lightning strike.

After speaking, he looked at Xu Qi'an with proving eyes.

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 taken aback, another word he had never heard before, electricity he knew, but what is voltage?

Instinctively, he felt that this was a remarkable 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 to Xu Qi'an: Brother, please explain clearly, what is voltage?

Please teach us. The other alchemists in white clasped their hands at the same time and said in unison.

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

Voltage, also known as potential difference or potential difference, is a physical quantity that measures the energy difference produced by a unit charge in an electrostatic field due to different potentials. Of course, you don’t understand what I said. Xu Qi'an coughed, with a serious face:

Electricity is the same as water flow, it will flow toward the low point.

Xu Qi'an raised the teacup and poured the water in it, It's okay to pour this cup on anyone, but if it's a waterfall, people who stand in it will be broken by the impact of the water, and even lose their lives. The same goes for electricity. So, I call this phenomenon voltage.

He uses this easy to understand example to explain voltage.

Si Tianjian's white clothes 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 cheered up: So, the reason why thunder and lightning hit trees in rainy days is because the trees are at a low point? The same is true for people. In addition, if it is only a weak current, we will feel paralyzed at most. And if you bear the bombardment of the sky thunder, you will die.

The truth is that the voltage of the sky thunder is so strong that it exceeds the limit that ordinary people can bear, just like a waterfall. The weak current is like a glass of water, which can withstand it.

Hearing Song Qing's words, the white-clothed alchemists were suddenly enlightened, excited to have obtained the profound meaning of the truth, and cast their eyes on Xu Qi'an for proof.

Um, is this the principle? Isn't the reason why trees are struck by lightning not the conductivity of rainwater? My middle school teacher didn't make it clear, and Xu Qi'an himself was not sure, with a smile on his face: Young children can be taught.

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

Yes, I'm the only one who has read and studied that alchemy cheat book. The content in the notes I sent to Si Tianjian is 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 many unheard of alchemy techniques.

At the scene of the unheard of alchemy, everyone's breathing became a little heavy.

Xu Qi'an smiled, and made a promise that made the white clothes boil: I decided to share the alchemy cheats with Si Tianjian.

Wow!

Nearly twenty alchemists were excited on the spot.

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

Of course, it also includes the follow-up alchemy cheats.

Never forget that the principle of alchemy is equal exchange!

Song Qing nodded, agreed with Xu Ningyan's reasoning, and asked the question on behalf of the juniors:

How much silver do you want?

Vulgar! Xu Qi'an said in a deep voice, How can alchemy be measured by money.

The ones that don’t cost money are the most expensive, he added silently in his heart.

Changle County Government, side hall.

Xu Lingyue held her sleeping baby girl in her arms, pinching a handkerchief, sobbing and crying.

Looking at the little beauty with pear blossoms and rain, the hearts of the Kuaiban's Kuaishou are almost broken. Unexpectedly, Xu Ningyan had such a pretty and beautiful younger sister.

Even when I went to the Jiaofang Siwang to catch the head, I was amazed by the little beauty.

The atmosphere in the side hall was a bit depressing, and the Kuaishou's faces were ugly and listless.

Wang Butou poured a cup of tea and placed it in front of Xu Lingyue. The little beauty cried and cried for a long time, and the tears never stopped. The woman was indeed made of water.

Miss Xu, don't worry, Lord Baihu will find a way to rescue Ning Yan.

Other Kuaishou expressed comfort and scolded Mr. Zhou.

The relationship between the elder brother and his colleagues is very good. Xu Lingyue was a little surprised that the angry expressions of the fast hands did not seem to be fake.

As if seeing her surprise, Wang Butou smiled: Ning Yan is a person worthy of respect.

Respect? Xu Lingyue was stunned, choked for a while, and said softly: Wang Catcher, can you tell me about my elder brother?

Wang Butou was silent for a while, and subconsciously lowered his voice: Actually, how can people like us have clean hands?

If you don't attack ordinary people, you have a conscience. As for those wealthy businessmen, it's not a matter of course to get money from them.

But your elder brother can't, whether it's a commoner or a wealthy businessman, he never blackmails. A while ago, considering the disaster the Xu family was in, I decided to take him to make a fortune. Blame, embarrassment, shame, admiration:

He smiled and agreed. Afterwards, I gave him five denarii, but he quietly returned it to others.

If you say that he is sensible, don't you understand the truth that when the water is clear, there will be no fish. But if you say that he is not sensible, he is very good at dealing with things, and he has a good relationship with everyone, and he is slippery. So he came out. It’s going to hurt everyone.”

Xu Lingyue listened obsessively, and the image of her eldest brother in her mind became taller, brighter and stalwart.

She has admired Xu Xinnian since she was a child, because everything is inferior and only studies are high, because her mother always instilled in her that the second brother is the only seed of the Xu family to study and will be the pillar of the future.

This kind of admiration reached its peak in the autumn of this year, after Xu Xinian passed the examination.

But the ensuing tax and bank case, the whole family went to jail, and when they were desperate and helpless, the elder brother opened up a way out for the whole family in desperation.

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 big brother is, just like saving them from prison a month ago.

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

Seeing the moment when the elder brother rescued the younger sister, Xu Lingyue felt that the image of the elder brother was equal to that of the second elder brother.

At this moment, upon hearing Wang Catcher's emotion, a high-minded, upright, principled and bottom-line image emerges spontaneously, which has surpassed the second brother who has always been 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 government office. When they saw their sister (daughter) who was safe and sound, the father and son were relieved.

Xu Lingyue raised her head, with tears streaming down her face, she mourned: Father, you have to save elder brother, if elder brother doesn't come back, my daughter will die too.

Ask for a recommendation ticket.
