When Lin Fan arrived at the "ordinary middle school", he was just in time for the middle school class bell to ring, so he casually found a classroom and went in.

Coincidentally, Lin Fan ran into Barlow in the classroom, which was a classroom in the second year of high school, and this class was history.

Barlow was surprised to see Lin Fan, and then he was surprised, and warmly invited Lin Fan to sit with him, and he drove away at the same table.

The class began, and the history teacher walked up to the podium with a pair of eyes and a textbook.

"Hello students, today we will talk about the history of the changes of the consortium. Why did it become a consortium in power before the cataclysm? Where have all the original government organizations gone? Please open page 32 of "New Era", the origin of the foundation. ”

Crooked than crooked, crooked than Bab.

The history teacher started to speak, and Lin Fan was very interested in the content of the lecture, so he listened carefully. Generally speaking, these things can only be glimpsed from the background information of the game, Lin Fan didn't expect to hear such a detailed past in a history class in Dongning City, and he was immediately fascinated.

It's a novel experience, something he doesn't waste time doing when he's a player, no matter what.

Lin Fan listened and listened, and suddenly a system prompt jumped out.

[Subclass detected: Trainee Historian, whether it costs 20 experience, 200 Aqua Star Common Currency Learning.] 】

Historian is not a rare subclass, and there are not many additional attributes, so it is common to find a library and read history books, and players will be able to trigger a job alert.

Lin Fan didn't feel anything unusual, and it didn't cost much, so he casually clicked "yes".

[Congratulations on becoming a "Trainee Historian", HP +10, Stamina +10]

A clear stream emerged in Lin Fan's mind, he was in a slight trance, and unfamiliar knowledge and information suddenly appeared in his mind, as if he had memorized it for decades.

"Damn, this historical knowledge can be like a skill, you can learn it as soon as you learn it?!" Lin Fan was shocked, and a storm turned in his heart.

In the past, through the system, he learned the psionic cultivation method, the marksmanship and the knife technique, and Lin Fan was not too surprised, because he was used to these violent skills when he was a player. But after taking office as a "historian" at this time, Lin Fan's feelings were very different.

It's the same as you're used to learning how to cook a dish, how to make a medicine, how to run faster, jump farther, and get stronger. But suddenly one day, through this golden finger, you instantly know the history of 5,000 years, and instantly understand a large number of poems and poems.

It's like a monster fighting and upgrading the God of War text, and a text copying public, the style is completely different, and the contrast is too great!

But if you think about it carefully, it seems that there is no essential difference between the two learned through the system.

"Alas, brain-burning, don't think about it, let's listen carefully first."

Lin Fan has always wanted to understand why he suddenly crossed over, to understand what is going on in this game world, to understand what is going on with the players, and to find out if he can return to the original world.

If he didn't figure these things out, Lin Fan was always worried that his people would disappear again in the next second, disappearing without a trace in this universe, and being erased in the long river of time, without any sense of security at all.

But now it seems that it is really not easy to figure out these things. Let's stop thinking nonsense, go to the top under the existing rules first, and then think about breaking the rules and seeking the truth.

With the knowledge of "trainee historian" as a foundation, Lin Fan listened to the lectures very easily, and sometimes even raised his hand to ask a few insightful questions.

The teacher who taught the history class saw that Lin Fan was tender-faced, and he was the same age as these sophomore high school children, and he never doubted Lin Fan's identity at all. After answering, he was full of praise for Lin Fan, praising him for thinking and learning, and using Lin Fan as an example, he encouraged other students to study hard and ask more questions.

By the time class ended, the classmates in the class looked at Lin Fan differently.

The female classmates are envious, adored and shy, their faces are red, and there are little stars in their eyes; The male classmates were jealous and jealous, their faces were red, and their eyes were even redder.

Then Lin Fan hurriedly ran away.

Lin Fan ran out of high school and went to a university not far away. This university, called Dongning University, is a comprehensive university that is ranked first in Dongning City, with a good faculty and learning environment.

It is said that Bop's wife, May, teaches in the Department of Medical Sciences here, which is why Barlow calls May Sensei.

Lin Fan walked to the teaching area and found that it was just time for the students to take a break after class, so when class was in session, he casually slipped into a classroom and found a seat to sit down.

The university is much more free than the middle school, the classroom is not fixed in the same position and seats as in the middle school, and the classroom space is very large, Lin Fan can find a place at random, which is not conspicuous at all.

The teacher walked slowly from outside the door, turned on the projector, and began the lesson.

This class is a spirit pattern class, and it is a spirit pattern class in the first year, and the spirit pattern science explained is very basic, and the classification and role of spirit patterns are being explained at this time.

"There are many ways to classify spirit patterns. According to different efficacy, it can be divided into variable temperature type, power type, and special effect type...... According to the number of psionic nodes on the basic spirit pattern, the spirit pattern can be graded according to the complexity, which is called the first-level spirit pattern and the second-level spirit pattern...... If a spirit pattern is a large spirit pattern formed by the combination of multiple basic spirit patterns, this spirit pattern is also called a composite spirit pattern......"

The spirit pattern, which is a supernatural product that appeared at the same time as spiritual energy after the cataclysm, is one of the most important discoveries of human beings in the new era.

Animals and plants have mutated and evolved because of their spiritual energy, and different kinds of spiritual patterns with different functions have begun to appear on the surface or body of animals and plants.

Wise warriors discovered this phenomenon, recorded these spiritual patterns, depicted the shape of the spiritual patterns on various carriers, and embedded spiritual energy on the spiritual nodes of the spiritual patterns, which can show various supernatural phenomena.

Some patterns can produce low temperatures, some patterns can produce high heat, some patterns can increase the hardness of objects, some patterns can make weapons sharper, some patterns can add corrosiveness, and some patterns can make explosives more powerful......

All kinds of features, a thousand strange things!

Naturally, in today's rampant monsters, these characteristics of the spirit pattern have been thought of being used to make weapons.

In order to distinguish them from traditional weapons, these weapons engraved with spirit patterns are called psionic weapons.

Psionic weapons have superior performance and are the most common weapons in the middle and late stages of Aquamarine, but now that the open beta has not yet begun, psionic weapons are very rare, and their performance is extremely unstable, making it difficult to use in actual combat.

The reason for this is that it has only been twenty or thirty years since the development of spirit pattern science, and the current environment has made the development regress and the productivity can not be liberated, which has greatly slowed down the development progress of the new discipline, resulting in spirit pattern science like a toddler baby, unable to stand up for a long time.

The second is because of the limitation of psionic energy.

Psionic energy, one is the psionic crystals in the monster's body, and the second is to mine energy deposits and refine psionic crystals from them. Due to the small number of warriors and the need to stay in the city to protect humans, the monsters killed are extremely rare, resulting in a shortage of psionic crystals, and it is impossible to promote research at all.

As for psionic spars, there are many types of new psionic mineral deposits, and mining and smelting methods need to be explored, and the major forces in the Western Continent are closed to each other and do not exchange core technologies, and the speed of development in this area is extremely slow.

On the other hand, in the Eastern Continent, the psionic spar has slowly prospered, and the spirit pattern science is also thriving.

It's far away, let's get down to business.

With the teacher's detailed explanation, Lin Fan listened carefully, and after listening for a while, a system prompt popped up in front of his eyes.
