Chapter 325: After the demolition team entered the underground of the mine, all the mine maps that Ivan had prepared before were useless. The little ones who could help him explore the path were exhausted because they exerted too much force when he fell. Sleeping heavily and being of no use, Alvin could only go find the underground metallurgical workshop by himself. Fortunately, Alvin is looking for a metallurgical workshop. The most obvious characteristic of a metallurgical workshop is that it radiates a large amount of heat to the surroundings. This is the best guidepost. ¡°If Alvin was looking for some other target, he might really be blind in this place. Following the gradually increasing temperature in the air, it only took Alvin five or six minutes to find the mysterious metallurgical workshop that the market merchants kept mentioning. Probably to facilitate the transportation of raw materials, or perhaps to circulate the air, the four doors of the metallurgical workshop were wide open. Through the doors, Ivan discovered that the metallurgical workshop was built in a huge hemispherical rock hall. The area is nearly a thousand square meters. A dozen first-level warriors, led by two second-level warriors, were responsible for security issues outside the metallurgical workshop. Ivan used the invisible barrier to observe around the metallurgical workshop for a while, but did not see any more guards. Feeling strange, he decisively walked towards a gate guarded by four first-order warriors. If the guard strength outside the metallurgical workshop was only this small, then of course it would not be able to stop Ivan's invasion. However, without knowing the guard strength inside the metallurgical workshop, Ivan decided not to alarm the outside of the metallurgical workshop. , the guards looked pitifully fragile to him. The spell effect of the silence spell is still continuing, but as a relatively simple first-order space spell, silently casting an invisible barrier is not a problem for Ivan. The disadvantage of the invisible barrier is that the light refraction is not perfect enough. It is okay when viewed from a distance. However, when viewed up close, you will find that there is an unnatural distortion in the air, which even a first-level warrior cannot hide. Fortunately, the location that Ivan is using is on the periphery of the metallurgical workshop. A stream of heat waves and water vapor radiate outward from the door of the workshop. Affected by the water vapor, the air will distort from time to time. Invisibility is used here. The barrier and invisibility abilities have also been greatly enhanced. At least first- and second-level warriors can no longer see any flaws. Soon, Ivan walked up to the human warriors, and a strong smell of sweat and body odor hit his nostrils. Human warriors do not have a heat-resistant physique like Ivan. Even after special heat-resistant training, under the invasion of the rolling heat wave, the clothes are still wet with sweat, and the concentration is inevitably much lower than under normal circumstances. Ivan paused, then continued forward, passing them easily and entering the smelting workshop. The temperature inside the workshop is higher than outside the gate. In the light of the red molten metal, workers with red upper body are coming and going in the curl of water vapor, carrying various ores and cooled materials. Metal. Ivan was even able to bathe in magma, so naturally he didn't care about the high temperature in the metallurgical workshop. He carefully avoided the metallurgical workers passing by and scanned the large and small objects painted in various colors in the workshop. After distinguishing their functions, a look of admiration flashed in his eyes, and then he began to focus on looking for the figure of the great craftsman Varu. After searching everywhere for a while, Ivan did not find anyone suspected of being the great craftsman Varu. After thinking for a moment, he quietly came to a corner and looked for an opportunity to capture an ordinary metallurgical worker into the barrier. A charming The human spell was thrown out, and the unlucky guy was immediately caught. He stood honestly in front of Ivan, and under the suggestion of Ivan's mental power, he told everything he knew. It turned out that when the first alchemy bomb exploded above the mine, the security captain of the metallurgical workshop, a third-level warrior, had already sensed something was wrong. He offered to escort the great craftsman Varu away, but he did not get Varu. Master Lu agreed, and when the second alchemy bomb exploded, he was like a cat with fried hair. Regardless of Varu's objections, he forcibly took him away. At the same time, the guard captain also took away the main force of the guard team. , here in the metallurgical workshop, only the three or two kittens that Ivan just saw outside were left. Hearing this, Aiwen was speechless. The guard captain¡¯s vigilance was a bit too high. Could it be that this great craftsman was often kidnapped or assassinated by Viscount George¡¯s enemies? But Ivan also knows that since the guard captain has taken precautions and dispatched a large number of people to take away the great craftsman Varu, even if Master Varu is still staying somewhere underground, waiting for the crisis to pass before returning to his post, He is not familiar with the place here, and finding him is still as difficult as going to heaven. Disappointed, Alvin could only temporarily suppress his thoughts about Avila Alloy and began to think about how to return to the surface of the mine. When Aiwen was thinking about this problem, he still stayed in the roomIn the corner of the workshop, he had no intention of leaving, because he thought it was possible that the guard captain suddenly lost his mind and felt that the danger had passed, and would take the initiative to bring Master Varu back at the next moment. In that case, he could easily I accepted this gift with ease. Speaking of leaving, if you don¡¯t look for a way out in the winding tunnels around you, then there is a flat and straight passage in the metallurgical workshop in front of you, leading directly to the surface of the mine, which is used by the metallurgical workshop to drain water. Smokey rock tunnel. All metallurgical furnaces in the workshop discharge waste gas through a metal pipe, which is a straight tunnel with a diameter of five meters. If you move up this exhaust duct, you can reach the ground in a straight line of about two hundred meters. However, Ivan has no doubt that if he really wants to do this, even if he climbs to the top, he will be covered by the smoke. It's smoked into bacon, but it's the kind that will cause poisoning if you eat it. Shaking his head, Aiwen woke up from his thoughts. Although it was convenient to leave through the exhaust pipe, the lethality of the smoke was indeed a problem. If he was a water mage, he could have a purification spell around him, but unfortunately he was a fire mage. mage. Although Alvin can also kill in the metallurgical workshop to cut off the source of smoke, the guards on the surface of the mine are not fools. The black smoke that has been flowing out along the exhaust pipe suddenly disappeared. Naturally, something went wrong down there. It is estimated that they will all be holding crossbows in a circle at the smoke exhaust port, waiting for Alvin to deliver the goods. Not thinking of any good solution, Ivan scanned the metallurgical workshop again, hoping that during the period of time when he was lost in thought, the extremely vigilant guard captain could bring back the master craftsman Varu. It was a surprise for him, but unfortunately after scanning around, Ivan found that the number of people in the metallurgical workshop had not changed much, so the so-called surprise was naturally out of the question. Although the number of people has not changed, the appearance of some places has indeed changed. Ivan noticed that in the corner that had been moved away, at some point, there were a few more large metal plates emitting heat. Judging from the color and the The texture was exactly the Avila alloy he had observed in the blacksmith shop before. It is not surprising that Avila alloy was manufactured here, because this is where the master craftsman Varu originally worked, and making Avila alloy is one of Varu's most important jobs. But Ivan looked at the newly released Avila alloy, and then at the various ores and fuels piled on the other side, and his heart suddenly became enlightened. There is no need to find any formula at all. Once you find the formula, you still have to purchase instruments and train skilled workers again. These things are not easy to do. It is better to just empty the place and the people will be gone. Take them all away, so that you will have the equipment to make the alloy and the workers to operate it. It is impossible for these workers to know the entire process of making Avila alloy, but they at least know the part of the process that they are responsible for. When combined, there may be various shortcomings, but it is definitely a complete formula. "If it had been anyone else, they would never have thought of packing up the entire metallurgical workshop, because they didn't have the ability at all, but if it had been Alvin, it would have been different. Silently communicating with Alvin in the small world, a few minutes later, Alvin openly removed the invisible barrier surrounding him, and then opened it amidst the shocked and puzzled eyes of the workers in the workshop. At the portal leading to the small world, two demon sisters with silver hair and blue eyes came out of the portal with more than twenty big demons. Behind these big demons were more than thirty little demons. Not to mention the little devils, who specialize in coolie work. These more than twenty big devils are all evolved from the little devils that the devil sisters used to use the blood left by Alvin when he left to help accumulate enough energy. Among them There are those five spider knights with the wind attribute. Of course, those five little spiders are no more than the size of basketballs now, and they look more like pets than riding animals. Calling them spider knights is really a stretch. Due to time constraints, these great demons, including the earliest evolved demon sisters Cecilia and Cecilia, are still only at the first level of strength. Fortunately, the opponents they need to face are not very strong, and they With Aiwen and Alwen behind him, it would be difficult to get injured, let alone die in the battle. "Oh, this is where you live, dadahhhhh, it stinks so bad!!" As soon as Alwin stretched out his upper body, he was hit by the strong smell of sweat in the metallurgical workshop and fell back. , it took a while to cover his face with a thick, moist cloth, and hesitantly moved out of the portal. At this time, Ivan had already commanded the more than 20 big demons to move all the guards. Knocked down. "Okay, okay, you, you, you, and you, you guys, take two big demons outside to watch. If anyone comes, come back and report it. If you can't make it in time, just destroy the tunnel., these are the blueprints and materials for blasting the magic circle. " "Don't just stand there, you lazy fools, quickly cast the fossil-to-mud spell and remove all these instruments for me. What, hot? What kind of devil are you afraid of being burned? "While guarding the captives who were kneeling on the ground with their heads held in their hands, the two demon sisters directed the demons and demons around them to start working, showing highly professional demolition qualities. "What on earth have they been doing in the small world during this time? Looking at Ai Wen is puzzled by the domineering sisters around him q!
