Lilith held a stack of textbooks in her hand and hurriedly ran to the classroom, this morning is the two classes of formation foundation and alchemy foundation, which are also two tutorial classes added on rest days at the request of the prison world.

Because since the trade between the two worlds, many products such as pills, array arrays, and talismans have become hot sellers, which can be regarded as an extremely stable import trade for merchants in the prison world. But in the long run, on top of the pills alone, there was a trade deficit of nearly 100 billion per month, which made the currency of the prison world depreciate year by year.

In response to this situation, a movement on the establishment of the Commodity Protection Law of the Two Realms was born spontaneously with the most famous trading empire in the prison world, the Gadogan Free Federation, and under the promotion of Yarut Murat and Liu Fu, this negotiation was held as scheduled, and many mutually beneficial treaties were signed during the meeting, including a simple alchemy technique and formation technology into the prison world.

This is also a treaty that Liu Fu granted in consideration of the characteristics of the medicinal materials produced in the prison world, and if he did so, it could also greatly reduce the pressure on the Burial Dragon Valley Danfang, like some simple pill refining, which could be subcontracted to the prison realm, and then the Burial Dragon Valley Danfang only needed to be responsible for the refining of pills with high grade and small output. This not only ensures the success rate of high-grade elixirs, but also saves Miao Poison and Alan from the boring work of mechanical production.

As a result, the birth of a "Two Realms Commodity Protection Law" has raised the economy of the Burial Dragon Valley and the Prison Realm to a new level, and now the Burial Dragon Valley can be said to be very rich, and its wealth is unimaginable to the mortal empire on the Elam continent.

The changes in the Elam continent are mainly in Kobo County, which is now full of high-tech goods from the Valley of the Burial Dragon and the Prison Realm, and technology has turned this primitive county into a powerful empire.

Originally, the distance from one city to another, with the fastest carriage, would take at least a few days or dozens of days, but now a flat and wide black oil road has been established between the cities - this is a special material from the prison world, which has the characteristics of rapid hardening, alternating winter and summer without cracking, and simple paving, so when it was just introduced, it was frantically grabbed by the city lords of all parties, for this reason, the prison world also set up a special construction company, called "Gadogan Road and Highway Administration" All the roads that were built by this company were unanimously praised, and Freya also made a lot of money from them.

There are also education, medical care, military, people's livelihood and so on, all of which have undergone earth-shaking changes, all of which make Harvey dumbfounded, sometimes he holds the monthly report, looking at the astronomical numbers on it in a daze, this is often tens of billions, hundreds of billions of inputs, which was not even dreamed of before.

Lilith pushed open the teacher's door, and it was already densely packed with people, at least three hundred.

"Ahem......" Lilith put down the textbook and turned to write on the blackboard, "Today's first lesson is the foundation of formations, and we talked about ...... last week"

She brushed a little bit and said as she wrote: "The third volume of the foundation of the formation, the second chapter, the sixth subsection, everyone take good notes, before class ends this afternoon, there will be a quiz, and those who fail will not be used next time." ”

Chalk rattles on the blackboard.

"First, the relationship between the formation node and the aura. Second, the change pattern of the formation node. Third, the specific use examples of formation nodes. ”

Lilith finished writing the board and turned around.

"Let's look at the first point, we say that the structure of the formation node depends on the actual effect of the formation......"

The students below worked hard to write, for fear of missing a word, and in addition to Lilith's gushing explanation, the audience was the sound of brushing.

Most of these students were representatives from the major trading houses in the prison world, and of course, they were all carefully selected people with only one purpose, that is, to learn simple elixir refining and formation carving.

“...... Many of the changes are in the list on page 133 of the textbook, and you need to memorize them, and I will immediately name them in the next class, and if you can't memorize them, you don't have to come again. Okay, there is still half of this class, we are going to visit a formation under the cliff on the west side of the Burial Dragon Valley, called 'Water Moon Ink Frost', everyone opens the appendix of the textbook, and the three hundred and fifteenth items of the large formation ......"

There was a clattering sound of flipping books below.

"Look, the bearing capacity of this formation is about 500,000 people, the main effect is psychedelic, after the formation is launched, the people in the formation will first have a sense of suffocation, the body feeling is drowning, the general person with a weak physique, at this time has already died, if you are lucky enough to survive, the second stage of the formation is launched, there will be a sky full of black frost, and the person who has a drowning body feeling before will be immediately frozen, and then gradually lose consciousness. After the formation is over, everyone must remember to close the formation eye, the position of the formation eye is between the seventh and eighth formation chains, and it needs to be detected with aura, there is no obvious mark, do you remember?"

"Remember!!" shouted the academy in unison.

Lilith nodded and continued: "Okay, now please follow me, let's go out of the valley from the west gate, this 'Water Moon Ink Cream' is three miles outside the door!"

With that, Lilith closed the textbook and put it on the podium, and immediately walked out of the classroom, and the students got up one after another and followed Lilith out of the classroom.

"Teacher Lilith~Hello~" a white wolf villager greeted.

Lilith smiled and said, "Your son is studying well, but you have to stick to class!"

"Don't worry, if that stinky boy doesn't go, I'll bite off his leg!"

"Teacher Lilith~Hello~" Another villager came to say hello.

Lilith said: "You can attend the parent-teacher conference next week, your stinky boy has caused a lot of trouble, and this time you have to take care of it." ”

The villager couldn't hold back: "Okay, don't worry, I will definitely go! I will beat him up today and give you a vent!!"

A group of people came to the western cliff side, a huge gate with a height of 100 zhang towered in front of them, which was built by Liu Fudu, the materials were of high quality, many formations were carved on the door, and there was a team of Kro guards in front of the door.

"Isn't this Miss Lilith?" the Captain of the Guard came running over and beckoned, "What, do you have any lessons to go out today?"

Lilith nodded and said, "Hu Wang, is it your class again today?"

Hu Wang said with a smile: "Recently, I saved up money to buy pills, so I asked the boss to arrange a few shifts for me, so as to earn more overtime pay." ”

Lilith said: "Oh~ That's hard for you, this class is five hours, it's tiring enough." By the way, please open the door, I'll take them to visit the Water Moon Ink Cream Array. ”

Hu Wang said: "Sister Lilith, is your pass card available?"

Lilith took out a wooden key from the storage ring and handed it to Hu Wang, who took it to register and gave it back to her, then turned around and walked to the door, took a cylindrical green crystal key from his neck, and inserted it into the hole in the door.

"Boom!!!!!! Bang!!!!!

When the door opened, a hot, dry wind blew in.

Lilith greeted Hu Wang and walked out first.

To the west of the Burial Dragon Valley is an endless desert, with constant wind and sand for many years, but fortunately there are cliffs and cliffs, so that the environment outside the valley is like heaven and earth.

Lilith turned around and said, "It's too windy outside, you can use the Wind Fixing Charm to relieve it!"

The students took out the Wind Fixing Talisman one after another to use, and almost everyone in the prison world now has a copy of this basic thing.

The three-mile journey was very close, and it didn't take much effort, and the group arrived next to the 'Water Moon Ink Cream' array.

Lilith stood still on the side of the formation and said, "You see, this kind of large formation usually covers an extremely large area, starting from here, extending thirteen miles on both sides, all within the range of the large formation. ”

As she spoke, she stretched out her hand and pressed the void, only to see countless formation nodes clearly displayed.

"Water Moon Ink Frost Array, within the scope of non-composite formations, is the most complex, you see, there are 173,460 nodes here, every seventy-seven nodes are a group, connected separately, you can regard these seventy-seven nodes as a formation unit, and then every seventy-seven formation units form a formation chain, there can be no slightest mistake, let's take a closer look, is there a white ball of light between the seventh and eighth formation chains, that is the eye of this big array, open and close must be operated on this... ...”

Lilith was talking happily when suddenly one of the students said, "Teacher...... You...... Look ahead, is someone coming?"

Lilith looked in the direction of the student's finger, and there were bursts of dust and sand in the distance, and she looked at it carefully, and her heart was suddenly shocked.

"All the students retreat, there is an enemy attack!"

It turned out that in the midst of the rolling dust and sand, a giant wolf rushed first, and on the back of the wolf sat a tall orc, this person was heavily armoured, and he held a mace in his hand, and in the howling wind behind him, there were countless wolf cavalry following.

Because these students are here to learn formations and alchemy, they have no combat ability, and as the wolf cavalry army approaches, all the students are full of panic.

Lilith frowned, she also knew that these students were basically powerless, although she didn't know what these wolf cavalry wanted, but she had to ensure the safety of these students, otherwise it would have a certain impact on the two realms.

"Hurry up! Retreat to the gate!!"

With a shout, all the students came back to their senses and hurriedly ran to the gate.

The dust in the distance was getting closer and closer, and the earth trembled significantly, and there were even bursts of shouts of killing in the wind.

Lilith stepped back a few hundred meters slightly, standing between the large array and the fleeing academy, and then took out a magic staff from the storage ring and waited for it, and at the same time she summoned Liu Fu in the valley to give an overview of the situation on her side.

Liu Fu was in the process of approving the documents, and he was also shocked when he suddenly received Lilith's summons, he didn't expect the orcs to come so quickly. At this time, there can be no more delay, he knows that Lilith is not in danger, her cultivation is Liu Xuan's personal inheritance, and the only thing he is worried about is those students from the prison realm, if something happens, the impact on the trade between the two realms will be great.

Thinking of this, Liu Fu immediately summoned Timos: "Immediately go outside the West Gate, there is an attack from the beast clan, Lilith is resisting alone, no matter what, we must ensure the safety of more than three hundred prison realm students!"

Timos was stir-frying for Bart, and when he heard the news, he immediately threw down the spatula in his hand and turned into a flash of lightning and went straight to Simon.

At this time, Hu Wang also saw that something was wrong outside, and saw that more than 300 students in the distance were running back lifelessly, and more than a mile behind the students was Teacher Lilith, she seemed to be waiting for someone to come, and then looked into the distance, only to see the dust and sand rippling, and the black pressure countless wolf cavalry was rushing towards the west gate.

Hu Wang shouted: "Immediately inform the garrison in the valley, there is an enemy attack at the West Gate!!!The rest of the people follow me to support Teacher Lilith!!
