Lady Leo looked at the demonized orcs who were approaching the wooden wall below with an ugly face, and if it weren't for the fact that the terrain below was not conducive to cavalry charges, she would have rushed out with the three hundred cavalry who were ready to go.

"Hey, this time I underestimated these orcs, I knew that I had let a knight come over, and now I only rely on the Wizard of Doron."

"Oh no, the goblins have already broken through the defenses!"

Suddenly, there was an exclamation from below, and Lady Leo's heart sank, and she set her eyes on the wizard Doron beside her.

Duo Lun pulled the hood of his head, walked over to the wooden wall, looked at the thousands of demonized orcs approaching, calculated the distance, and whispered a strange-sounding incantation.

A silent ripple of energy enveloped the demonized orcs beneath the wooden walls.

The orcs shrouded in ripples suddenly trembled, and their bodies suddenly began to melt, and finally turned into a puddle of green water, and Duolun wiped out more than half of the orcs below in one fell swoop, which is the horror of this professional.

When the rest of the orcs saw this terrible scene, their eyes showed a look of extreme fear, and they threw away their weapons one after another, and crawled in a row, screaming and fleeing into the distance.

"Chase!" Mrs. Leo pointed her sword, and the rest of the army immediately chased after her with their weapons.

It didn't take long for news to come back from the front, and this pursuit not only wiped out the remaining orcs, but also found a batch of goods in the orc's temporary lair, which was apparently plundered by the group of orcs from the passing caravan.

When he went back to Rogue Town, Lin Fan had an extra dictionary-like book in his hand, which was a book about alchemy, one of the trophies of this battle, and after discovering this book, Mrs. Leo immediately handed it over to Lin Fan.

After returning to his residence, Lin Fan asked Daisy to arrange for those apprentices, and then began to flip through the book by himself, he found that most of the books were strange patterns, he guessed that these patterns were the alchemy circles for alchemists, but he couldn't figure out what each pattern meant.

At the end of the book is a portrait and a name, which, according to the wizard Doron, was written by a great alchemist named Canaan, who came from a very famous family.

It is said that in the territory of the Eastern European continent, seven of the top ten alchemy equipment are made by the alchemists of this family, and some people even rumor that there are even "forbidden level" alchemy equipment in this family.

When Lin Fan used his spiritual power to feel the strange pattern, he suddenly found that there seemed to be a very mysterious power on it.

He seemed to sense something, but he couldn't grasp it, like flowing water running through his fingers, passing without a trace, leaving only a cold feeling.

Lin Fan suddenly became interested in these alchemy arrays, and he suddenly had an idea, if alchemy and technology were fused, what kind of chemical reaction would occur? I suddenly had some anticipation in my heart.

According to some of the information he learned, alchemy is actually a process of conservation of energy, or more precisely, a process of chemical reaction, which is to change the structure of materials through external energy and give special properties to the finished product.

The decisive role in this process is the spiritual power, spells, and alchemy circle.

In the process of alchemy, spiritual power is a medium that communicates the elemental magic between heaven and earth, the magic array is like a converter, bringing together all the materials and elemental magic, and the spell is the catalyst and rules, accelerating the entire transformation process and determining the final result.

Among these three elements, the most important is the alchemy circle, which directly determines the quality of the final product, and the second is the alchemy spell, which, like the spell of the wizard, is also the secret of the alchemist.

After Lin Fan finished reading the book, he asked Daisy to prepare some alchemy materials for him, these things were all sent by Mrs. Leo, and after preparing the materials, he left the cave, found a hidden clearing on the mountain peak, and began to prepare for the experiment.

The whole process is very simple, first of all, use alchemy materials to outline an alchemy circle, then put materials on top of the circle, and finally use spiritual power to communicate elemental magic, activate the circle, and recite the spell.

However, when Lin Fan began to operate, he found that it was difficult, when sketching the magic circle, if there was any deviation, it would cause the magic circle to fail, he had spent nine materials to outline the alchemy circle, and only after he successfully sketched one of the simplest alchemy circles in the book, after success, he put an iron sword into the magic circle, plus some flame stones.

Then he began to use spiritual power to connect the magic circle to communicate the elemental power between heaven and earth, and activated the magic circle, Lin Fan knelt down on one knee in front of the magic circle, the basic requirements of alchemy, and the left and right hands respectively pressed the two symmetrical lines outside the pattern.

This is very important because the elemental energy enters and is instilled into the circle through the human body.

When everything was ready, Lin Fan began to induce spiritual power to attract elemental power, and then used spells to reorganize the alchemy materials in an orderly manner.

At the beginning, the whole process was quite smooth, after he activated his spiritual power, some red points of light began to float around him, which were fire elements, and then the fire elements surged up and entered the magic array.

The alchemy circle then activated, bursts of fire light appeared from the lines above, the flame stones began to melt, and the gathered fire elements surged towards the iron swords in the array with a unique rule, and formed some patterns.

These patterns were not formed randomly, but were influenced by Lin Fan's spiritual power, which meant that whatever he wanted to look like in his brain at this time, the fire element would use it as a specimen to form what kind of pattern.

Just when the pattern was about to be completed, an accident happened, and the fire elements that were rushing to the alchemy materials suddenly became unstable, and finally exploded directly, blasting the entire iron sword into pieces, and a wave of fire rolled up directly from the magic circle, forming a fire tornado several meters high.

There was no doubt that this was a complete failure, but Lin Fan was not discouraged by this, but became more interested in alchemy, and for the next period of time, he did not experiment again, but instructed those apprentices to make some parts in the cave.

Because he received a message from Mrs. Leo, in a few days, she was going to go to Boulder City, and Lin Fan also wanted to take the opportunity to go there, Boulder City was different from Rogue Town, it was a large city nearby, and there was a branch of the Alchemy Guild in it.

Three days later, two metallic rifles appeared on the cave's workbench.
