"Saltpeter!"

That's saltpeter!

A thought quickly took over the brain like a virus, adrenaline hormones were secreted wildly, and the whole mind was filled with an unprecedented sense of excitement. Pen ~ fun ~ pavilion www.biquge.info

Even though the Eastern Continent has always been closed, most people with a little ability under the perennial war will choose to move to the other three continents for development, and Wang Dakuo is one of them. The Western Continent is the second richest continent, and Wang Dakuo came to Kesen City, one of the most prosperous coastal cities in the Western Continent, with a passionate gold rush dream.

He bought cheap materials from low-level adventuring groups in various places near Kesen City and sold them to make a profit, and this time he was extremely lucky to find the fluff of the rare Roland lion at a super low price in a stupid rookie with little experience, although it was not as valuable as the mane, but the fluff was also a precious material on the Roland lion after all. So he and his cleverness came to the opposite side of the martial arts arena to set up a stall, and the people who came and went to the magic field were mixed, and it was the Emperor's Birthday these days, and he had been counting on someone who knew the goods to buy it.

He had been sitting for three days, and there were many people who came to see it, and there were many people who recognized the fluff, but no one was willing to buy it at a high price of five gold coins, which made Wang Dakuo very depressed, he really didn't want to sell such a precious material to the Alchemist Guild at a low price.

Wang Dakuo looked at the black-haired young man in front of him who was dressed in clean white clothes but had a dirty bun temperament inside and out, and looked at his poor and sour appearance, Wang Dakuo sighed in his heart: "When will this lion velvet be sold?" ”

The black-haired boy sometimes picked up the magic crystal and sometimes picked up a piece of fine iron, Wang Dakuo was very irritable when he saw it, his face showed a trace of impatience, and the next moment he saw the black-haired boy's eyes light up.

"I'm going to get that lion velvet!"

Wang Dakuo couldn't help but doubt his ears for a while: "Hey, little ghost, don't make trouble if you don't buy it, do you know that the lion velvet is five gold coins?" ”

As soon as these words came out, the black-haired young man showed a difficult look on his face, and Wang Dakuo saw that the impatience was even stronger, and just as he was about to drive him away, the black-haired young man gritted his teeth and said.

"Five gold coins is really a bit too expensive, if I add these two things, I'll buy them!"

After that, the black-haired boy pointed to two things, one was a second-level fire attribute magic crystal, which stored the equivalent of a second-level storage magic array, and the other was a slightly larger flint stone, although it was not small, but after all, it belonged to the most common type of ordinary material, and it was worth selling for one or two silver coins at most. The combined price of the two is a little more than forty silver coins, which is not too much of a loss, at least I can finally sell this Roland lion velvet!

"These two are worth close to fifty silver coins...... Wang Dakuo deliberately showed a difficult look, but after seeing the black-haired boy frowning, he was afraid that the black-haired boy would not buy it because it was too expensive, so he said again: "That's it, just sell it to you!" ”

When he received it, he spent fifteen silver coins but had a profit of several gold coins, thinking about this, Wang Dakuo was in a good mood, so he simply sold it.

After speaking, I saw the black-haired young man take out five gold coins from the bulging cloth bag around his waist and throw them over, and after catching them, he showed a courteous look, and hurriedly put the lion fluff and fire magic crystal and the flint stone into two cloth bags and served them with both hands.

He saw that the bag was full of gold coins!

After the figure of the black-haired boy completely disappeared into the flow of people, Wang Dakuo hurriedly put away the stall, quickly ran to the back streets and alleys where few people went, and took out the communication crystal. A few minutes later, a shadow light curtain appeared, Wang Dakuo talked to him, his voice was very small, although it was difficult to hear clearly, but he could clearly see the greed in Wang Dakuo's eyes.

Of course, Lin didn't know this, and he didn't notice the guy who was following him all the time. Lin was just extremely excited, and quickly returned to the Yanyu Pavilion, and the person who followed him could only sigh secretly and give up after seeing him enter the Yanyu Pavilion.

After returning to Yanyu Pavilion, Lin didn't even eat, and locked him in the room directly after asking Liu Daming for a pen and paper, and didn't come out for a day, Liu Daming didn't know what this mysterious junior brother was doing, and he didn't bother him.

Until the next morning, blood crawled all over Lin's eyeballs, trembling and throwing the almost exhausted pen again, staring at the paper full of patterns on the table.

"Finally...... Got it! ”

Looking at the stacks of design drawings on the table, Lin was deeply satisfied.

Lin yesterday's Lin accidentally discovered the existence of saltpeter, and in an instant, Lin's various inspirations exploded in Lin's brain.

Saltpeter is the main ingredient in gunpowder, but when he thinks of saltpeter, he thinks of something else...... Nitrocellulose, and nitrocellulose is the main ingredient of bullets, at this time, speaking of bullets, everyone must have guessed Lin's thoughts.

That's ...... Gun!

The planet with magic power, which is an efficient universal energy source, although there is technology, it is still at the level of the old feudal society, and even firearms have not been invented, even the southern continent, which is known as the most technologically advanced technology, has developed magic technology with magic as the core of energy.

After all, even if someone invented such a thing as a musket by accident, its practicality is far less than that of a fireball.

Even in modern times, ordinary firearms are not very lethal, but they have two advantages that magic cannot match, that is, they do not need to consume mana at all and have unparalleled speed.

But the existence of the magic circle gave Lin a bold idea - to engrave the magic array on the bullet!

"Can you replace nitrocellulose with an airblast array? The airflow propulsion generated by the directional airblast magic is only stronger than nitrocellulose, but what if the two are combined? Well...... Not to mention the power, it is estimated that ordinary barrels may not be able to withstand it, and it seems that it is necessary to purchase some metal reinforced with magic power, and there should be a lot of things today......"

The revolver, an ancient firearm improved by a guy named Colt on the former Earth, is a type of pistol and is Lin's final design choice. It's not that I don't want to use automatic pistols or even all kinds of energy weapons in Dream Knowledge, the latter is naturally not mentioned, although the former is better than the revolver, but it has a fatal problem in itself, that is, the magazine ......

Compared with the six single rounds of the revolver, the bullets in the magazine of the self-loaded former Earth modern pistol are tightly spaced, and the ordinary ones are fine, but what you want to make is a bullet with its own magic, and if the circle is too close to each other, it may disturb the flow of magic power in it, and this disadvantage is pushed back and forth that only a special revolver magazine engraved with stable magic power can have the effect of carrying magic bullets.

There are also a lot of terrifying weapons in the knowledge of dreams, and those Lin can be regarded as seeing them with his own eyes through Naga's eyes, such as the Star Destroyer Cannon, the Railgun, and even the Star Fortress...... And he really detonated a directional explosion of a bombardment shell before he died.

Boom Cannon, the representative work of genius quantum solitude, is based on the photon black hole theory of quantitative solitary quantity. Using the impact of explosive photofluid particles at high speed and high temperature to deal damage, the original model has the power to completely destroy a large planet.

The bombardment cannonball was originally the final killer weapon left by Lin, and the vibration signal transmitter implanted in his heart would release the detonation signal of the bombardment cannonball when his heart stopped beating, and the bombardment cannonball was placed in the former Greenwich Emperor Tianwen Observatory in the United Kingdom, setting the range west of the prime meridian (the zero degree meridian of the earth), covering a small part of the entire Americas and Africa, and now it must have turned into cosmic dust......

After all, the earth is his hometown, and Lin doesn't want the small county town where he was born and raised to disappear forever, so he only destroyed half of the earth, and left a gravitational stabilizer in a small bungalow that was once called a home in that small county town, so that the remaining half of the earth will not collapse because of the problem of gravity.

Quickly pulled his whimsical thinking back, Lin, who was a man of action, immediately sorted out his clothes and brought the money bag that was getting more and more deflated, and when he came to the first floor of the Yanyu Pavilion, he saw the two sitting opposite each other talking about something.

The first floor of the Yanyu Pavilion is a teahouse opened by the master, and there is an inner room for receiving guests. The teahouse is usually taken care of by the subordinates, and the people who come and go are all Orientals. And now after all, it is early in the morning, and there are not many people in the teahouse, so its voice can naturally be heard clearly. And this content aroused Lin's interest, so he stopped.
