According to the assessment of the city guard commander, the situation on the scene was caused by the high-level magic cast by a senior magician who was at least equivalent to a silver-level high-level warrior, or even by a great magician with the strength of a gold-level warrior, which could have such amazing destructive power.

  Thinking of this, the squadron commander couldn't help but feel his scalp tingling.

  Great magician? This is not an existence that they can easily provoke.

  So he turned to the junior water magician who was fighting with the hostile magician for information.

  Unfortunately, however, the magician had his tongue cut by the enemy thieves, temporarily lost his ability to speak, and seemed to have suffered a severe mental injury, with empty eyes, and it would be difficult to recover in the short term.

  "Report to your Excellency immediately!"

  The squadron commander had no choice but to grit his teeth and make a decision to send people to ask for help from the sponsor behind him.

  Although the amount of 10,000 gold talans is huge, it is insignificant for your Excellency who controls the underground world of Kelan City.

  At present, they can only hope that the leader can return as soon as possible...

  At the same time, when Old Jimmy went to the Mercenary Guild to issue the mission and bring back the Browns, Jia Lan and his party had already set off for Doom Castle.

  For several months, various materials stored in the dock warehouse area have been hired to load and transported to the warehouse cleared by Doom Castle.

  A team of hundreds of skilled craftsmen and hired workers has been assembled.

  Although Doom Castle has a bad reputation and rumors of haunted incidents continue to occur, the workers are obviously no longer afraid of those ghost rumors due to the rising popularity and generous salaries.

  This ancient castle complex is huge.

  Jia Lan currently does not need a large area of ??space, and only ordered people to clear out the largest main castle and its surrounding ancillary buildings for use as workshops and hired dormitory.

  The square in front of the main castle, which was originally overgrown with weeds, has been cleared and rows of sheepskin tents have been built.

  A large amount of supplies have also been purchased and stored in the rooms of the main castle.

  Jia Lan could only express regret that the hired workers would rather live in tents than in the castle. Although they were willing to work for high salaries, they were still afraid of the rumors of haunting.

  The thick rock walls have not decayed after years of erosion.

  Except for the slightly weathered and mottled surface walls, the main building is actually intact.

  It only needs a little tidying and repair to be put back into use.

  To build such a spectacular castle complex, the capital investment required is undoubtedly extremely huge.

  As Captain Casey predicted earlier, even if this castle has been abandoned for a long time, its purchase cost is expected to be as high as tens of millions of gold talans.

  However, at present, Jia Lan has successfully obtained the right to use this castle at a very low cost of only 5,000 gold talans per year, which is undoubtedly a very cost-effective deal.

  Given the notoriety of the Castle of Doom, Jia Lan quickly conducted a comprehensive inspection of the castle after arriving. Similar to the teams that had planned to come to exorcise the evil spirits, he did not find any abnormalities except that it was slightly eerie.

  This tale has been unlawfully obtained from Royal Road. If you discover it on Amazon, kindly report it.

  After all, it is reasonable for such a long-abandoned and poorly maintained castle to be slightly eerie.

  Currently, the procurement of materials and security protection for the Castle of Doom has been entrusted to the Golden Two-Headed Dragon Mercenary Group recommended by President Clark.

  The squadron includes hundreds of bronze-level mercenaries and twelve silver-level mercenaries, responsible for the security of the entire castle community, and this service is provided free of charge.

  At the same time, Kenmet Abigail, the leader of the Golden Two-Headed Dragon Mercenary Group, has publicly announced that he plans to transform the Doom Castle into the headquarters of the Golden Two-Headed Dragon Mercenary Group in Coran City to cover up the fact that Jia Lan and the Iguana Fang Mercenary Group have settled in.

  After completing all the arrangements, Jia Lan began to lead the craftsmen to dismantle and assemble the equipment in the large wooden boxes that arrived.

  This batch of metal parts made by alchemy includes a large number of gears, chains, screws and metal rods of different models.

  As various strange-shaped parts are gradually assembled in Jia Lan's hands, the interlocking gears are tightly stacked, and their complexity is comparable to the astrolabe used by astrologers.

  Then, Jia Lan used a rough and heavy black iron shell to wrap the complex internal structure, and embedded a fire crystal about the size of an egg at the bottom of a pure silver barrel-shaped liner in the construction equipment.

  The bottom of the pure silver liner is engraved with a fire element conduction rune array. When it comes into contact with the fire crystal, the conduction rune glows slightly and begins to release hot temperature. At the same time, the pure silver liner also emits a silvery-white light.

  Jia Lan quickly pulled a switch handle next to the construction equipment and opened the copper water tank valve connected to the pure silver liner. The clean water stored in the water tank flowed into the pure silver liner that had been burned at high temperature and was instantly evaporated into steam.

  With the violent eruption of steam, the connected air valve was opened, driving the gears and chains inside the construction machinery to start running at high speed, making a clanging noise.

  Jia Lan directed the hired workers to carry the raw materials of medicinal materials to the upper hatch of the construction machinery and dump them one by one.

  Immediately afterwards, a buzzing sound came from the inside of the machine, and then at the exit below the construction machinery, fine medicinal powder began to slowly flow out.

  After confirming that the construction machinery was running normally, Jia Lan breathed a sigh of relief and then led the craftsmen to assemble other parts of the construction machinery.

  Jia Lan carefully connected a large number of different parts to each other and invested a lot of time in assembly and debugging.

  In the end, this unique construction machinery formed a huge metal monster in the castle square.

  Under the watchful eyes of many craftsmen, hired workers, helpers, members of the Iguana Fang Mercenary Group and Clark Abigail, the president of the Mercenary Guild, Jia Lan solemnly flipped the switch of the construction machinery.

  With a deafening roar, the hired workers quickly moved the baskets of medicinal materials to the hatch of the assembly machine and dumped the medicinal materials into it.

  With the strong vibration, these materials seemed to be swallowed by an invisible force and gradually disappeared.

  After grinding, the powder was sent to the next assembly machine through an animal skin conveyor belt, mixed into a mixed powder according to a certain proportion, and then sent to a row of huge sealed metal medicine crucibles, added with water and heated to boiling.

  In the next twenty or so processes, everyone stood together in front of the last process of the full set of assembly machinery, watching the hired workers pull the handle of the giant medicine storage tank.

  Rows of closely arranged brass nozzles instantly filled 20 straight-cylinder ceramic medicine bottles on a thin wooden pallet. The tray filled with medicine was pulled away by the hired workers and pushed onto a slowly rotating animal skin conveyor belt.

  The hired workers standing on both sides screwed the caps coated with beeswax on the medicine bottles and sealed them for boxing.

  President Clark swallowed his saliva involuntarily, and asked with a slightly dull look: "Master Jia Lan, what is the daily output of this assembly machine?"

  Jia Lan, who was holding a notebook and continuously observing and recording, frowned and looked at the first "fully automatic medicine preparation assembly line" he built with regret.

  Obviously, the results this time were somewhat unsuccessful.

  This assembly line was designed and manufactured by Jia Lan based on the principles of certain assembly equipment in the soul memory from an unknown world.

  However, since the assembly knowledge mastered by the soul from an unknown world contains a large amount of knowledge system that Jia Lan cannot understand, and many parts cannot be manufactured.

  Therefore, Jia Lan can only refer to some understandable parts of the alien soul assembly knowledge to design this unqualified semi-finished product.

  Some of the parts and processes that cannot be realized and manufactured were replaced by him in other ways, such as the fire element conduction array, etc.
