The small town of Netling is located at the foot of the mine, just a few hundred meters away. Although the size of the town is not large, of course, it cannot be compared with a place like Most, but although the sparrow is small, there are all kinds of instructors of various combat professions in the town, as well as blacksmith shops, engineering shops, tailor shops, etc.

Because the town of Knightling is the only place under the mine that can be replenished and repaired, the town can be regarded as lively on weekdays, with an endless stream of players and miner NPCs coming and going on the street, and even some of the NPCs in the town are miners, and the rebirth hall is very lively, and where there are many people, there are disputes, and there are casualties. Once the player releases their souls after death, they will return to the Rebirth Hall here, so the whole hall is not crowded, but there is always a steady stream of new souls appearing here.

In the middle of the town, there is an Iron Tooth Tavern, which contains the Irontooth Snake Gall wine, which is a specialty of the town of Knightling. At this time, Ye Fei was tasting this slightly bitter but hot 'wine', and his brows furrowed: "I swear, I have never drunk such a bad wine in my life." ”

Opposite him, a middle-aged man who was also bald opened his mouth and let out a low laugh, but he enjoyed tasting the wire snake gall wine, and squeaked with satisfaction. Your experience is not enough to taste the taste of this, aha, sniff it gently, don't you smell a sad past? ”

Ye Fei snorted, rolled his eyes, and was about to say to the guy in front of him: You are an engineering technician, not a philosopher.

Cavis, the engineering tutor in Knightling Town, shook his head and repeated the brewing process of an ordinary wire snake gall wine several times, and only when Ye Fei's patience was about to be worn out did he raise his head and look over: "So, young man, although you are also an engineering technician, you are a student of that old fellow of Nomo, what else do you need to learn from me?" Oh, I can be honest with you, I will, Nomo basically will. And there are some things he can't, and I can't teach you, even if you invite me to a drink, it's impossible. As he spoke, Cavis smiled a little treacherously, and his fingers shook slightly, "You know, we old guys always have to have one or two things at the bottom of the box, called, well, called unique, aren't they?" This kind of thing, can't leak out casually, or someone won't have to rob you of your job? ”

Ye Fei shrugged his shoulders and said indifferently: "Yes, that's it, you need to stay ahead in some aspects." But I didn't come to you to learn your skills, although I was interested to know what you were good at. ”

When Cavis heard this, his already red face turned dark purple, and he exclaimed exaggeratedly as if he had been insulted: "Oh my God. You don't know what I'm good at? Aha, you little fellow, didn't Nomo tell you that Cavis of Knightling was an out-and-out genius? Bomb-making genius! ”

"Well, I've heard him say the word genius, but that's his own. As for you! Ye Fei shook his head, revealing a sneering smile, "He didn't even mention your name, oh, I came to this town to know you for the first time, Mr. Cavis, the mentor of engineering." ”

One of Kavis's faces immediately stiffened, angry, angry, lost? There were all kinds of emotions, and the weirdness on his face made people can't help but spray rice, and after a while, he suddenly exhaled a breath and shouted angrily: "Ha! I knew, I knew, this guy wasn't going to take me to heart. Well, he's jealous, because the explosives he makes aren't as powerful as mine, so he's jealous of me, and doesn't want others to know about my existence, he's afraid that I'll steal his limelight, and although he occupies such a good place in Most, his students aren't much more than me. ”

Dynamite? When Ye Fei heard this, he immediately became interested, leaned over and said with a smile: "You mean that you are good at making explosives?" Hey, I haven't really heard of that. ”

Cavis glanced at Ye Fei: "Of course, the explosives I made are famous in the entire City of Most, and they are not ordinary explosives, they are explosives used to blow up mountains." Do you know that at the beginning of the excavation of the mine in Wutie Mountain, it was impossible to mine it by manpower, and it was all because my explosives blew up a hole that allowed people to enter and exit freely. ”

Nima, the explosives that blow up the mountain, this is a good thing, it's powerful enough!

Ye Fei was excited, his body twisted and adjusted his posture, licked his lips and said, "Tutor Caves, if I want to learn your skills in making explosives, what conditions do I need?" ”

Cavis glanced at Ye Fei and shook his head gently: "You? It's not enough miles, hey, tell me what you're doing here. ”

Ye Fei knew that if he wanted to learn the recipe for making explosives from Calvis, he couldn't rush for a while, so he could only spend time with him slowly. He thought for a moment and said, "Mentor Cavis has lived in the village for so long, I would like to ask if anyone has lived in the village in the past two years and is mining nearby. ”

Cavis looked at Ye Fei in confusion: "What do you want to know about this?" ”

Ye Fei tapped the mercenary badge on his chest: "For a mercenary mission, I need to find someone." But I got the news that this person is hiding here incognito. ”

"I see, but I'm not obligated to help you...... Oh oh oh oh my gosh, what do I see? Silver ore, cute little one, do you want to buy me with this ore? Cavis grabbed the silver ore that Ye Fei suddenly threw out, and there was already a green light in his eyes, greedy, this is a full greedy color.

Ye Fei just took out a piece of silver ore, not much, just one, which made Cavis immediately re-export, you can imagine how precious this kind of thing is. Especially now, Nomo's side has received the mission issued by the city guard, won't the NPCs in the small town of Knightling, which is also part of Moster City, receive the task? What's more, this Kavis is very good at making explosives, how could the city guards leave out such a 'talent'?

Therefore, Ye Fei believes that Cavis must be the same as Nomo, he must have received the task, and since he has been tasked with it, there will definitely be a shortage of silver ore and tungsten iron. Knightling was outside the mine, but the mines were very closely guarded, and even Nomo said that it would take a lot of risk to bribe the guards there to get a little ore, so it would be difficult for Cavis to get it.

Sure enough, when Cavis saw the silver ore, his eyes were green, and he eagerly raised his head and looked at Ye Fei: "How much silver ore do you have, and wolframite, I want all of them!" ”

Ye Fei smiled and said, "20 pieces of silver ore, in exchange for a piece of news just now." I can't take it out if I have more, so it's up to you if you want. ”

Originally excited and excited, Cavis sat down in a chair decadently, drooping his eyelids and complaining: "20 yuan? That's not enough, I need at least 100 pieces of tungsten ore and 100 pieces of silver ore to be enough. ”

When Ye Fei heard this, a strange feeling rose in his heart, 100 yuan again? Is it a coincidence that Nomo and Cavis are so in the same demand, or is it a - mission? If it's really a task, it might be a bit of a trick. He glanced at Cavis: "I can't get 100 pieces of tungsten ore, but I still have a little stock of two ores, so it's up to the mentor to make a price." ”

When he heard this, Cavis cried out; "How many do you have? Give me a refreshing one, lad. ”

Ye Fei looked at his backpack and said with a smile: "20 pieces of wolframite and 92 pieces of silver ore, this is all I have." Oh, even the one on the table is 93 pieces. ”

Cavis glanced at him resentfully: "Which little bastard just said 'too much and can't take it out'?" Well, although tungsten pyrite is still a little less, it is already good. What price do you want? ”

Ye Fei groaned slightly, and said: "The news I want, and the unique skills you are good at, I want to learn your unique skills." ”

Cavis's bitter old face suddenly turned red: "Unique? No, no, no, it can't be, I can't pass on my skills to you. He shook his head like a rattle, and refused Ye Fei's request with a sip of wine. The reason why he was able to become Knightling's engineering instructor here was because the explosive powder he made was of the highest quality in the whole of Most. If you give an account of your old background, your status may be seriously affected.

Ye Fei smiled and said, "I don't need to learn all your recipes, you just need to pick a few recipes and teach them to me." Of course, you can't fool me with that worthless thing! ”

Kavis's heart moved, and he was a little hesitant, if it was just a few recipes, it was negotiable. After thinking about it for a while, he raised two fingers, and his face shrunk into a pitiful ball, and said: "The formula of two elementary engineering can only be like this at most, and if it is more, I will drink the northwest wind." ”

Ye Fei nodded, the formula for primary engineering was already very good. No matter how advanced he is, he can't learn it anytime soon, he adds: "It has to be exclusive to you, and you won't pass on these two recipes to anyone else." ”

Cavis rolled his eyes: "Do you think I'm stupid?" You can't teach it to others, this can't work, but I can promise you that you can't teach it to others in the last month, otherwise you will sell my formula everywhere, and I won't be at a loss? "Cavis is also playing his own wishful thinking, if it is just a junior engineer's formula, the value is indeed not very high, even if it is announced, it is nothing, and even he is already a little moved, and after giving the formula to Ye Fei, he will start selling it immediately, this unique formula will definitely attract many engineering technicians to come and buy.

Unexpectedly, Ye Fei's words shattered his wishful thinking, and as a last resort, he could only add a deadline.

Ye Fei said with a smile: "Deal, then Mentor Kavis, please show me the unique junior engineer formula you have, I need to pick two." ”

"You still need to choose. I've only had two specific junior engineer recipes. With that, Cavis immediately took out two sheepskin scrolls and threw them on the table in front of Ye Fei, "What about tungsten iron and silver ore?" ”

Ye Fei didn't say a word, he immediately took out the things he needed and handed them to him, and then opened the two formulas.

"High explosive powder (bronze grade): 3 rough stones, 1 tungsten coal stone, and 1 tungsten iron powder are required! You can make even more powerful bombs! Junior Engineer is required (proficiency of 4000 or above is required). Flame Explosive Powder (Bronze): 3 rough stones, 1 tungsten coal stone, and 1 fire magic powder are required! Junior Engineer is required (proficiency 6000 or above required). ”

Ye Fei was dumbfounded when he saw the formula, the formula itself is not a problem, and the requirements for learning are not a problem, on the contrary, the higher the learning requirements, the happier Ye Fei is, because this means that the quality of the formula is better. The problem is the materials mentioned in the formula, tungsten coal stone is an additional product of collecting tungsten ironite, Ye Fei has a lot of it around him, but wolframite powder is made of tungsten iron ore, and his tungsten iron ore is given to Cavis, and he has no piece left. As for the fire demon fan, he hadn't even heard of it.

"Nima, it's useless again!" Ye Fei was depressed for a moment, so many ores were exchanged for some useless things.
