Shi Xiaohan's sudden appearance made Gu Xu's lecture involuntarily pause for a moment, and also made the eyes of almost all the students present fall on her.

Shi Xiaohan felt that this must be the most embarrassing moment in his life.

She lowered her head and looked at her toes, her earlobes slightly reddened, and she wanted to dig a hole in the ground on the spot.

At the same time, Gu Xu saw her standing in a daze, so he said to her with a smile: "This young lady, why are you still staying outside?" ”

His tone was gentle.

But it doesn't sound like an exchange between peers, more like a teacher's reassurance to a student.

Shi Xiaohan thought angrily: This bastard actually pretended not to know me! And in front of me, there is a shelf for teaching!

However, in front of everyone's eyes, she didn't dare to quarrel with Gu Xu, so she could only blush, and explained hesitantly: "I'm sorry, I'm ...... I overslept today, Gu ...... First...... First of all, sir, I'll come in......"

Saying the word "sir" almost exhausted Shi Xiaohan's strength.

Her voice grew quieter, more like a mosquito, and the last words were so muffled that they couldn't be heard clearly.

Seeing Shi Xiaohan's expression, Tao Xi, who was sitting in the front row of the lecture hall, was quite surprised.

She didn't expect that Shi Xiaohan, who has always been lively and cheerful and smug on weekdays, would show such a shy and shy side in public.

"Then move quickly, don't grind."

Gu Xu was also amused by Shi Xiaohan's performance. However, he deliberately restrained his smile and urged with a straight face.

Shi Xiaohan suddenly slipped to the back of the lecture hall like a little rabbit with a "whoosh" - it was almost impossible to find her figure in the crowd without using her mental perception.

She secretly decided: Gu Xu bullied me like this today, and I must clean him up in the future...... I'm going to find an excuse to fight him, and then beat him to a pig's head and leave him in bed for three days and unable to get up.

…………

In this eye-catching rune lesson, Shi Xiaohan's suddenness was just an insignificant vignette.

Gu Xu soon continued to teach the course in the expectant eyes of the students:

"As talisman masters, you should all know the history of the birth of the talisman technique.

"According to the book, Fu Seal is the language of the gods and the medium of communication between the Great Dao of Heaven and Earth. It is the same as the method of cultivation, which was taught to us by the immortals above the nine heavens.

"But in fact, the earliest talisman seals of the Great Wilderness are extremely rough and have extremely simple functions, and there are no more uses other than setting fire to kill ghosts......

"It is with the passage of time, under the continuous improvement and expansion of the generations of talismans, it has today's diverse functions and quite complete theoretical system.

"The books written by the predecessors have greatly reduced the difficulty of drawing talismans - beginners do not need to understand the 'Tao' in the talismans, they only need to strictly copy the patterns and strictly implement the process to draw talismans with special functions.

"However, sometimes, it is this kind of 'convenience' that does not need to think or delve into it, which to some extent restricts our thinking and suppresses our desire to think deeper.

“……

"I'll give you a simple example.

"Suppose you are a literati who makes a living by writing stories.

"One day, a scene suddenly popped up in your mind - a poor scholar and the daughter of an official eunuch fell in love at first sight in the temple.

"This image makes you feel a strong creative passion. You begin to use it as the core, to enrich the identity and background of the couple, to improve the process of their encounter, to try to construct the whole world in the story.

"When you're conceiving a story, it's likely that what comes to your mind is not words, but video clips, images, dialogues, and even emotional swings that make your heart flutter but are difficult to describe in words.

"They're fragmentary, they're reticulated, they're chaotic, they're something that only you understand.

"However, the way in which the reader receives information is always linear and sequential. You can't just cram the inspiration out of your head to them.

"You have to sort out the mess in your head and put it in an orderly line.

For example, first introduce the background of the world, the identity of the hero, the identity of the heroine, and then introduce why the two of them went to that temple......

"Even in the same scene, all kinds of information need to be effectively arranged – for example, first describing the weather, then describing the temple environment, and then describing the appearance, clothing, and demeanor of the two people......

"But the words are not the jade pendants recorded by the Exorcism Division after all. It is impossible to record all the details that the creator has in mind.

And when readers see the text, they will spontaneously restore the picture, the situation and even the mood swings in their minds.

However, due to the inevitable loss of information in the process of text communication, what readers eventually imagine must be very different from the original inspiration in the creator's mind.

"For example, the appearance of the heroine, maybe a thousand readers can imagine a thousand different appearances.

“……

"Since the definition of 'character' in books is 'text', it must also have the problem of information loss.

"Take the 'Flame True Talisman' as an example.

"The monk who originally created the 'Flame True Talisman' is like the creator of the story. One day, he felt the presence of the 'Avenue of Fire' and entered a state of epiphany.

"He had a strong urge in his mind to record the Tao.

"But as we all know, the Tao is very abstract and difficult to fully describe in words.

"It's like an inspiration for creators.

"Therefore, the talisman seal he finally drew will be very different from the inspiration given to him by the original 'Avenue of Fire', and a lot of information will be missed.

This also means that the sigils drawn on our books are themselves flawed. There is still a lot of distance between them and the real Heaven and Earth Dao.

"And the process of improving the talismans is to constantly improve them, so that they are closer to the 'Dao' and have less information missing."

Speaking of this, Gu Xu temporarily stopped teaching, took out a kettle from "Xianyunju", and moistened his dry throat with water.

There was silence in the lecture hall.

Some of the students stared at him intently, trying to digest the contents.

Some students lowered their heads and quickly took notes with charcoal, trying to write down his words word for word, and then take them back and think about them repeatedly.

Jia Xiuguang, who was sitting in the first row, frowned more and more.

Tao Xi, who was not far away, blinked thoughtfully.

Only Shi Xiaohan, who was hiding in the corner of the lecture hall, was thinking about a problem that was completely different from everyone else's on the same channel.

She thought to herself silently: "Poor scholars and eunuchs...... Gu Xu gave this example, is it because he thought of my experience with him? ”

"But the problem is that we didn't meet in the temple......"

PS: I'm not very satisfied with the first draft of this chapter today, so I deleted it and rewrote it, sorry for the word count is a little less. Write more tomorrow to make up for it.
