In the tongs pot, a teaspoon of black particles bursts into flames, quickly releasing the heat, and white smoke rises, then burns out in a second, leaving a shallow layer of residue.

Wren had a smile on his face, pleased with his results.

The black powder he prepared had not yet reached its maximum power, but limited to the purity of the raw materials, he did not have the purification tools in his hands, and he could not accurately measure the chemical composition of these raw materials, which was the limit of what he could do.

Nevertheless, it is enough for the manufacture of bullets.

After putting the prepared gunpowder into a jar and sealing it, Wren immediately set about making a gun.

He opened the three-dimensional structure diagram on his phone and looked through the unlocked firearm.

Pistols were excluded in the first place, because of their small caliber, coupled with the use of black powder bullets, which limited their lethality. Moreover, the pistol parts are more delicate, the processing is difficult, and the requirements for metal materials are higher.

Rifles are also impossible, the several assault rifles and submachine guns unlocked are air-conductive automatic weapons, which cannot use black powder bullets at all, and can only be shot and stuck.

There are two types of sniper rifles, but they are not suitable, and the requirements for materials and processing accuracy are too high.

In the end, the only option you can choose is a shotgun, which is also known as a "troll".

Wren often plays games, and naturally he has heard the saying: In front of trolls, all beings are equal.

Shotguns have a large caliber, strong firepower, and a wide killing area, making them suitable for melee weapons. Wren had only played with a gun once before at the shooting range, and his shooting ability was similar to that of an ordinary person who had never touched a gun, and if he was given a pistol or rifle, it would be too difficult to get started, and he was not sure that he would be able to shoot an enemy at close range.

But if it's a troll in your hand, you're much more sure.

And black powder bullets are also suitable for shotguns, the disadvantage is that there is too much smoke after firing, but it cannot be avoided and can only be overcome.

There are three or four shotguns in the unlocked three-dimensional structure drawing, excluding the air-conductive semi-automatic gun model that is also not suitable for black powder bullets, and Wren finally chose one of the most familiar and classic shotguns - Remington M870!

This pump-action, manual reload, seven-round capacity, compact, reliable and easiest to manufacture.

Wren has used this gun in many games.

He himself is a mechanical major, and even if he does not have a three-dimensional structural drawing, he can figure out the structure of the M870 by himself, but it takes more time.

In view, the M870 is completely split into parts, the barrel, trigger, tubular magazine, screw, spring, handguard, wooden stock...... All the large and small parts add up to a total of 71.

Wren first carefully observed all the parts, disassembled the gun body in succession, reassembled it more than a dozen times, and then demonstrated the working principle when firing, the process of throwing the case and loading the bullet, and soon kept the structure of this shotgun in mind, and classified the parts to determine the order in which they were manufactured.

Zoltan's workshop stocked a lot of metal, including plates, steel pipes, and springs of various strengths, which could be used to make guns.

"Fortunately, there are guns in this world, and there is the profession of gunsmith, otherwise I would have been stumped just by making a qualified spring. ”

Wren was secretly glad and decided to start with the barrel first.

But before that, you have to start the machine and learn how to operate it.

He tinkered with the steam machine for a while, and he probably understood what it was and how to do it, so he shoveled some coal under the boiler, lit it, heated it, and steam came out of the boiler, and soon the machine was running.

Flutter flutter flutter ......

The flywheel turns, the steam rises, and the machine makes a regular grinding sound, which is uncomfortable to listen to in ordinary people, but it seems like a beautiful song to Wren's ears.

He mounted the cutter head, held the barrel in place, and then pushed the wrench to start cutting.

When you are immersed in work, time always flies so fast that you forget that you need to eat.

"Wren, why are you still here?"

It wasn't until Zoltan rushed into the workshop and shouted for Wren to turn off the steam machine so that the noise would not come up from the basement and disturb the guests' rest, that he realized that it was almost midnight and that he had been in the workshop all day!

There was a series of gurgling sounds in his stomach, a strong feeling of hunger came up, and his hands and feet were a little sore.

He withdrew the coal from the furnace, and the steam machine slowly quieted down.

Zoltan said a few words to Wren dissatisfiedly, and casually picked up the barrel that had just been processed, and originally just glanced at it with some curiosity, but when he saw it clearly, his eyes couldn't help but change.

"You made it?"

Zoltan gently rubbed the barrel with his hand, and with his many years of experience, he could naturally see the extraordinary features of this pipe.

The dark tube body flashed with black light, obviously after special treatment, one end milled out of the thread, the incision was neat and smooth, without the slightest defect, the other end was cut in half, leaving only half of the side, although I don't know what the thing is for, but just looking at the level of craftsmanship, I feel that it is not simple.

"I can't see that you still have this skill, not much worse than the best mechanic in the city of Longsander. Zoltan was sincerely admired, even if he was replaced to get started, he would not do better than this.

"The boss has won the prize. ”

Wren laughed secretly, in fact, he was also a little amazed at his level, he had not operated a machine tool for many years after graduation, but he didn't expect that not only did he not regress, but he was even more powerful.

However, most of the credit for this is due to the three-dimensional structure diagram in the mobile phone.

He only needs to drag out the parts in the three-dimensional drawing separately and coincide with the barrel that needs to be processed, just like having a physical object to compare, and process according to the drawing, and the difficulty is much reduced.

"Call me Zoltan. ”

The dwarf corrected Wren's name for himself, and asked curiously, "Wren, is this a gun barrel? Is it too long? The caliber is so large......

Wren hesitated, he knew that if he couldn't hide it from Zoltan, he would be found out sooner or later.

"Haha, if you don't want to say it, forget it, I won't steal your secret craft. Zoltan put down the barrel of the gun and said with a smile: "But if you make it, you must let me see it." ”

"Okay. Wren nodded.

After briefly cleaning up the workshop, Wren went to the hotel lobby and found that there were still a few tables of people playing cards so late, and it seemed that they were going to fight until dawn.

Ordered an extra amount of potato stew with beer, and Wren sat alone at the corner table and ate it.

Since he hadn't eaten for almost a day, the potato stew, which didn't taste very good, tasted particularly delicious, and Wren enjoyed his dinner while watching the guests playing cards.

Among them were several transcendents, one of whom was an acquaintance, the same guard he had seen on the street before. The shield and long sword he had on his back were thrown at his feet, he grabbed the cards in one hand, held the wine glass in the other, and kept spewing trash words in his mouth, his opponent was so angry that his face was red, but he dared not speak angrily.

"He can't come in in the morning and play cards until now!"

"Is it really that fun to play cards?"

Wren didn't understand very much, and thought that when he was free in the future, he could try it himself.

Halfway through the meal, a figure came in from outside the door of the hotel, and Zoltan, who was playing cards with others, turned his head and saw this person, and immediately threw away the cards in his hand to meet him, and shouted happily: "Roger!"

"Zoltan. ”

Roger's voice is very magnetic and very nice.

Compared with Zoltan's enthusiasm, Roger was expressionless, looking a little cold and gloomy.

He looked like a young man, but he had gray hair like an old man, simply combed to the back of his head, and looked extremely handsome, except for a scar on his left eye, as if caused by the claws of some beast, and the wound ran down from his forehead down his left eye to his cheek, but fortunately the eye was intact.

However, his eyes are also abnormal, and the amber pupils are erect like cat's eyes, which is quite frightening at first glance.

In addition, he wore a pale blue armor, half leather armor and half chain mail, extremely well-made, with a wolf's head pendant necklace around his neck, and two cross-swords side by side behind him, the hilt of which protruded diagonally from his right shoulder.

Such a peculiar costume that even some guests who were playing cards looked at it curiously.

"Witcher!"

Someone exclaimed in a low voice.

Wren knew in his heart that witchers are a very strong and extraordinary profession, but for some reason they have a bad reputation, are not popular with people, and are often resisted.

The characteristics of this transcendent class are very obvious, especially the dual swords on the back, which are almost a sign unique to witchers.

At this time, Roger's eyes swept around the hotel, and everyone who looked at him was stunned for a moment, inexplicably frightened, and involuntarily looked away. Even those transcendent beings couldn't bear it like ordinary people, and they didn't dare to say anything.

This scene made people's hearts nervous, knowing that this was a very powerful transcendent.

Wren was also swept by the other party's gaze, but fortunately he reacted very quickly and lowered his head in time to pretend to be eating.

The entire hotel lobby was quiet for a few seconds before returning to normal.

Zoltan wanted to hug Roger, but found that he couldn't reach it, so he had to pat the other party's arm hard, and said happily: "Old friend, it's been almost ten years since we last met, where have you been all these years, why haven't you been in touch with me?"

Roger shook his head silently, as if he didn't want to mention his experience.

He walked over to the counter, untied his sword and put it in his hand, sat down rather tiredly, picked up the glass that Zoltan had brought him, and drank it in one gulp.

Wren sat farther away, the noisy hall muffling out the two of them.

He turned on the phone's interface, turned on the camera function - that is, the "soul eye", first glanced at the other people a few times, and then pretended to glance at Roger inadvertently.

In the next second, Wren saw Roger's soul.

Then, as if struck by lightning, his whole body stiffened, as if he had seen something he should not see, and as if blinded by the strong sunlight, his eyes stinged, and tears flowed at once.

"Damn! What is this?"

Wren screamed in his heart, quickly closed the eye of his soul, buried his head in the potato stew, and swallowed his tears into his stomach.

At that moment just now, he vaguely saw as many as a dozen layers of golden souls, and in the depths of the soul, there were even as many as two-digit element runes!

"Is this a legendary witcher?"
