The plane of Reos is completely different from the Earth.

Although the physical form on the surface is the same as that of the original universe, in reality the essence of matter is definitely no longer atoms and molecules, but a small structure called an element.

As a result, a large part of the physics and chemistry knowledge that Don studied was useless.

After coming to this world for more than a year, although he quietly prepared gunpowder, it was a pity that he did not succeed, and the gunpowder he prepared could not successfully explode because of the lack of fire element.

It wasn't until Don was instructed by Todak that he discovered that the gunpowder he had prepared lacked a precious material, igneous crystal. Only with the addition of fire crystals can the gunpowder explode successfully.

The gunpowder prepared by the dwarves is basically the same as the recipe of Donn, and the only big difference is the fire crystal.

But fire crystal is a precious magical material, and once fire crystal is added, the cost of gunpowder is astronomical.

Expensive gunpowder was of no use to Don at all, after all, the professional itself was very powerful, and the primary gunpowder weapon could not deal with the powerful professional at all.

Once a professional is promoted to a legend, even machine guns and cannons are useless, and in the face of gods, even nuclear weapons cannot destroy the opponent.

Only cheap gunpowder can equip a large number of low-level mercenaries, forming a crushing advantage over bronze-level professionals.

Abandoning this failed invention made Don very depressed for a while.

The successive successes of inventing several commodities made Don gradually arrogant, and in his heart he may not be able to look down on the technologically backward Leos natives.

Compared to the original earth, this world is full of mysterious energy, which is the core of magic.

The magic web is ubiquitous in this plane, and it runs through the entire world, providing magic to all magical creatures.

But this kind of provision is not free, every time the magician uses the magic net to cast a spell, the magic net will absorb the spiritual power in the body. It is by extracting this spiritual power that the magic net can be transformed into an inexhaustible source of mystical energy.

The amount of spiritual power is related to the hidden attributes of the magician, and only creatures with strong mental power are more likely to learn to use various magic.

If you release spells for a long time and constantly release mental power, it will affect the mage's physique.

So even if the mages have good physical attributes, their health is not high, and they look a little weak.

Magic is a vast and profound science, and even any spell embodies the wisdom of the Leos plane.

Level 3 magic is already the pinnacle of low-level magic, and at this level of magicians, their foundation is already solid. Therefore, learning level 3 magic will increase the difficulty.

It only took a dozen days for Don to learn a second-level magic, but three weeks later, he still had no clue about the first third-level magic he had learned.

The first level of magic that Don learned was the Strong Acid Breath, and the reason why he chose this spell was because for Don En the Powerful Acid Breath was the easiest to learn.

Tang En already has an understanding of the nature of acidity, and is also good at using acid magic, whether it is a first-level magic second-level strong acid ball, or a second-level magic strong acid arrow, Tang En has been able to use it proficiently.

The strong acid breath is in the same vein as these spells, and there are many similarities in the configuration of the spells. After three weeks of study and derivation, Tang En had deduced the configuration of this spell.

But when it was carved in the spiritual power space, there were always accidents, and Tang En tried twice in a row, but it was unsuccessful. On the contrary, it caused me a splitting headache and was very uncomfortable.

As a last resort, Don had no choice but to ask Marianda for advice to see if there was a way to solve the problem.

It's winter, and everything is normal since Rednor's return, and the orcs seem to have lost their tracks. Tang En and the others are still doing business as usual, and they can bring them a steady stream of cash every day.

It's now winter, and with two heavy snowfalls, there's already a lot of snow in the Horn Forest.

Winters in northern Xinjiang are very cold, with heavy snowfall. Although this can make the land more fertile, it makes the winter in northern Xinjiang very unsuitable for living organisms.

The physical strength of the natives of the Reos plane, coupled with the backbone of the profession, allowed this place to be gradually opened up by humans and turned into the territory of the Hadema Empire.

Donn pulled open the thick felt and walked into the small cave where Marianda lived.

Marianda has been living here for half a year and has made a lot of changes to this cave. Now the cave has been divided into different areas such as the Magic Library, the Magic Laboratory, the Ash Factory, the Meditation Room, the Living Room, and the Bedroom.

And as Don and the others have been preparing to operate this place for a long time, the space of this cave is constantly expanding.

Every day, more than fifteen mercenaries, under the command of Dadri, are constantly renovating and digging this cave.

The floor of the cave has been covered with thick felt, and the outside has been made of solid wooden doors. There are several huge braziers in the cave, and the timber room is full of air-dried wood.

Clusters of flames lit in the brazier, and the temperature in the cave was just right for the warmth of the brazier, not very cold.

Don walked in and found Marianda looking at a magic notebook, and Don looked at the cover, which was supposed to be Scrim's magic notebook.

"Is there something wrong?" asked Marianda, putting down her notes.

"I can't come to see you if it's okay. Don said.

Marianda smiled and said, "Judging by the way you look, there must be something to ask me." ”

"How do you tell. Don asked.

"It's a secret, you can guess. Marianda laughed.

Don quipped, "I can't guess a woman's secret." ”

"No kidding, what's the matter with you?" said Marianda, waving her hand.

"I'm about to learn the strong acid breath, and I've already successfully deduced the configuration, but I can't succeed all the time, what is the reason for this?" Don put away his joking thoughts and asked cautiously.

"How could it be so fast? You advanced to level three in less than a year, and you became a mage in less than two years before you were promoted to level five. Your rapid promotion makes me very worried. Marianda panicked, the magic note in her hand fell on the felt, and she said with a look of despair.

"Don't worry, there's nothing wrong with my body, I'm not a child of killing, that's definitely guaranteed. Don said solemnly.

"Besides, you can become a seventh-level arcanist at the age of twenty, and I am already twenty-two years old this year, so what's so strange about becoming a fifth-level arcanist. Donn continued.
