I studied abroad in modern times

No matter how hard Zheng Shan exerts her force, the electric potential generated through friction is extremely small, and the electric sparks are simply invisible to mortals.

But the people in this classroom are not ordinary people.

The perception of monks far exceeds that of ordinary mortals.

What's more, there are many disciples who have practiced spiritual eye techniques like the "Dongxu Spiritual Eye".

How could they not see that not only Zheng Shan was also uncultivated.

Zheng Fa on the side did not use any spells.

Therefore, the small electric spark was like a thunder, which struck the classroom of thousands of people into deathly silence.

Zheng Fa looked at his master staring at the silk in his little sister's hand, with a complicated look on his face - like puzzlement, like shock, but more of a reflection.

Zheng Shan shrank her neck as she was stared at by so many people, as if she was a little scared.

Zheng Fa touched her head and said with a smile: "Don't look at her, everyone, she doesn't understand anything."

The younger sister is just an actress - she just follows the script.

The leader shook his head and said: "If Junior Sister Huang hadn't said that this little guy has no Dao body..."

He paused and was silent for a long time before saying: "So, what do you think Leifa is?"

Other disciples also looked at Zheng Fa. The scene just now could be said to have subverted their perceptions.

The current leader's doubts are exactly what they want to know most.

Zheng Fa thought for a while, then drew his fingers twice in front of him, and a light curtain appeared in front of him.

"Master, I thought that thunder method - actually has two sides, one is thunder and the other is method."

The words "Thunder" and "Fa" appeared in the light curtain.

"Thunder is a phenomenon."

As he spoke, ripples appeared on the word "Thunder" in the light curtain, turning into streaks of lightning.

Zheng Fa continued:

"The law is a tool."

After saying that, the words "Thunder" and "Dharma" on the light screen turned into the words "Phenomena" and "Tool".

As soon as these two sentences were said, Senior Sister Zhang's face moved slightly, as if she had some realization.

But the rest of the people were confused and seemed unable to understand.

But they had a feeling - what Zheng Fa said seemed to be an unprecedented definition in the Xuanwei world.

Zheng Fa paused.

He saw a trace of anxiety on his master's face.

"Keep talking!"

Uncle Pang and Uncle Huang glanced at him -

No, didn't you think that your apprentice was against Tiangang?

Are you listening so enthusiastically now?

…

Seeing that they were confused, Zheng Fa was not in a hurry to answer, and asked again:

"Then who can tell me where the various lightning techniques today come from?"

Zhou Qianyuan rushed to answer: "Inherited from our ancestors!"

Zheng Fa nodded and said: "That's true, but how did our ancestors create this thunder method?"

Everyone looked at each other, the words came to their lips, but they didn't know how to say it.

It was the master who said: "The way to observe the sky is to follow the way to the sky."

Zheng Fa clapped his hands and praised: "Isn't the way of heaven just a phenomenon? Isn't the way of heaven just a method?"

After hearing this, everyone felt that they understood a little bit, but they also felt that something was missing, and they all fell into deep thought.

Zheng Fa smiled and looked at the light screen.

Between the phenomenon and the tool, there was suddenly an additional word - "knowledge".

Everyone was not a fool, and they immediately understood what Zheng Fa meant, with a sense of enlightenment on their faces.

I saw the words on the light screen began to change again.

Finally, it condensed into three sentences——

"Observe phenomena and summarize knowledge."

"Use knowledge to create methods."

"Knowledge is power."

…

"Knowledge is power?" The leader murmured to himself, feeling that this sentence was extremely simple, but it seemed to describe the essence of the immortal method.

But Uncle Pang frowned and said: "Master Nephew, you said knowledge is power. Then this knowledge depends on everyone's observation and comes from everyone's own understanding. Doesn't that mean that this knowledge is important to everyone? All different?”

When he said this, he couldn't help but glance at Senior Sister Zhang.

It seemed like he was remembering the previous fight between the two veins.

Zheng Fa nodded and said: "This is the shortcoming of the past immortal methods - they lacked experimentation."

"experiment?"

"Not every understanding can be called knowledge." Zheng Fa thought for a while and continued: "Theories that have not been confirmed by experiments can only be conjectures."

Senior Sister Zhang stared at Zheng Fa, seeming to know that he had now talked about the essence of her theory.

"The simplest proof is the process of ancestors creating spells - they observed the runes in the air, used spiritual power to simulate the trajectory of the runes, and then produced spell effects."

"This...is the most basic experimental proof."

As soon as this was said, everyone understood.

"According to this, didn't our ancestors also prove it?"

Uncle Pang frowned.

"So, they created immortal magic, but past empirical evidence often stops there... unable to summarize more essential knowledge."

After saying that, Zheng Fa sighed.

He shuttles back and forth between the modern world and the mysterious world, so he is naturally better able to understand the differences between the two worlds.

In his opinion, in terms of wisdom, ability, and mind, the monks in the Xuanwei world are all good...

Even the immortal magic makes these monks destructive and vitality far stronger than modern people.

However, monks from the Xuanwei Realm rarely ask the most essential questions——

What is aura?

Why are magic spells effective?

What is the essence of cultivation?

Of course they have creations, but these creations are probably the accumulation of coincidental discoveries from generation to generation. In simple terms, there is no set of research methodology.

In Zheng Fa's opinion, the biggest difference between the two worlds is:

Modern people are good at understanding the world, but it is extremely difficult to transform the world. Let's not talk about anything else, just say that extending lifespan... Modern science has been around for hundreds of years, and humans have not been able to completely break through their own physiological lifespan.

For the cultivators of the Xuanwei world, transforming the world is too simple.

They don't even need to ask those boring questions, they just need to enter the Tao and cultivate immortals, follow the path of their predecessors, and they will naturally gain powerful power and a long life.

This simplicity has greatly suppressed the spirit of exploration of many people.

In fact, if it weren't for the existence of declining spiritual energy, I'm afraid most people don't expect any new methods.

Zheng Fa's luck is that on the one hand, he has received modern education and knows a little about how to understand the world.

On the other hand, he has the opportunity to practice immortal methods...

In today's class, Zheng Fa wants to do not just talk about his own thunder method, but to talk about methodology through the discussion of thunder method.

But judging from the expressions of the disciples, they probably didn't quite understand.

He had expected this question, and Zheng Fa continued, "For example, just now, when I asked you what thunder magic was, your answer was actually the knowledge that seemed to be the truth in the Xuanwei Realm - thunder magic can only be controlled by cultivators, because only by using spiritual power can the power of heavenly thunder be generated."

"Then my little sister's experiment just now... proved the error of this knowledge."

After saying this, everyone immediately understood a little.

"So, thunder magic has nothing to do with spiritual power?"

The head of the sect said slowly.

"Very good, Master, you have been able to summarize new knowledge through experiments!" Zheng Fa praised.

When the head heard this, he grinned at first, but immediately found something wrong...

He slowly put away his smile and stared at Zheng Fa.

Traitor!
