Missing 500,000 jinnars, Su Lun's whole person is not good, if he knew that Keaton's head was so expensive, he would have left him a whole corpse if he said anything, but unfortunately it was too late.

These potions in front of him are not of much use, such as corpse oil, such disgusting things are ready to be destroyed directly, and the effect of other venoms is not bad, as for the plague potion, Su Lun hesitated for a moment and left, this thing can be used on the enemy.

In fact, if the plague potion is discovered in time, it is not easy to destroy a city, as long as there are priests and wizards who use magic or spells to purify, dispel, and remove poison, it can also be solved, and this thing is to fight a surprise attack.

The power of the explosive charge is also good, the range is large, the power is strong, if it can be mass-produced, it will be invincible on the battlefield, this thing is much more powerful than a grenade. If you can get the secret recipe and build a grenadier team, you will be invincible on the battlefield.

Or let those harpies carry this potion and fly directly over the target for carpet bombing, and the effect of the city can be blown up.

"Hathaway, can you deduce the recipe for the explosives?" asked Suren as he picked up a bottle of explosives.

"The recipe for the explosive charge? This is a bit difficult, and I can't be sure of the exact time. Hathaway flipped through the books and replied, "But the cost of this explosive agent is not low, and you must be mentally prepared for the mass production you want." ”

"It's okay, isn't it just money? Now there is money in Zhenbei City. Su Lun said with a heroic face, after annexing the gray dwarf Orlando, the number of Jinnar alone in Zhenbei City is now tens of millions, plus hundreds of thousands of trade income every month, it is not a problem to buy a principality.

"Alright then, I'll do the deduction, but I'd suggest you recruit a few alchemists or wizards, I have too much work right now and I have limited time to spare. Hathaway said.

"There is a real need to recruit more alchemists and wizards. Suren looked at Hathaway's lab and nodded.

"It's just that Zhenbei City is too remote now, and its popularity among wizards is very low, so it's probably difficult to recruit wizards. Su Lun said with a little headache, although Zhenbei City has developed well, but even now, there are not many people who have taken the initiative to come to Zhenbei City to join, and even those scholars are forced by Su Lun.

"Do you have any good suggestions?"

"Most wizards are short of money, so please use the money. Hathaway is also a little helpless, many wizards are otaku according to the current saying, and they are either doing experiments or doing research every day, or they are meditating and practicing spells, so that they can serve the nobles, and the only reason is money.

"Well, that's all. Su Lun was a little helpless, in fact, he had something in his hand that could attract a large number of wizards to come, that is, Mithril, as long as there was some rumor, within a month, a large number of wizards would come to the door, but the consequences of that would not necessarily be whether Su Lun could keep the silver mine.

"Then I'll go first. Suren put the potion away and prepared to leave.

"Wait, I'm going to make a rock golem, you can help me. Hathaway said.

Su Lun of the Rock Golem had been taught in the trial space before, each of them weighed several tons, had thick skin, and although it moved a little slowly, and there were no spells to attack these weaknesses, it was still very useful on the battlefield, otherwise the wizards would not have listed them as regular troops.

As for the stronger Steel Golem, Hathaway can't build it yet, the Steel Golem needs a large soul crystal stone to activate, Suren only has a few pieces in his hand, or he obtained it by killing the necromancer Keaton, and if you want to get a large number of large soul crystals, one of them needs to be cultivated by yourself, and the other is to go to the bottomless abyss.

It was too bloody to cultivate this method by himself, Su Lun didn't think about it, this kind of thing was only done by some wizards in the Witch King era, and then it disappeared in the Witch King Era, this kind of thing was listed as taboo, and now the only way he could think of to obtain a large number of soul crystals was to go to the bottomless abyss.

As long as it is an elite-level demon there, you can get a large piece of soul crystal after killing, kill high-level demons, and you can also get a legendary-level soul crystal, and even the demon's divine power, of course, the difficulty of doing so is very high, the Arcane Empire once invaded the abyss, and those powerful Arcanists drove the floating cities into the abyss.

This led to the fall of several Abyssal Demon Gods, and it was also during those wars that the gods began to fear the power of the Arcanists.

As for cultivating large soul crystals on their own, this kind of thing is what the devil is best at, they will lure the greedy into taking the bait through contracts, and then use various methods to lure the contractors to fall, and set up various traps, it is said that after suffering, there is even a chance to obtain legendary quality soul crystals, of course, this statement has not been confirmed.

However, the devils lure people into depravity, let them indulge in their desires, and then harvest souls have a high chance of obtaining high-quality soul crystals. It is said that the method of cultivating soul crystals in the era of the Witch King was learned from the devil.

There are many materials for rock golems, from ordinary granite golems to the top-of-the-line obsidian golems, and the difficulty of building them varies greatly, and the price varies greatly.

An ordinary rock golem costs fifty or sixty thousand jinnars, while an obsidian golem costs almost one hundred thousand jinnars. The Obsidian Golem's magic resistance and physical resistance are not comparable to those of ordinary rock golems, and even the Iron Golem cannot compare to its magical defense.

The golem built by Hathaway is an ordinary granite golem, and the soul center can use medium-sized soul crystals, and there are more than thirty pieces in Suren's hands at this level, all of which are the contributions of necromancers, speaking of which, this is really a good person, not only sending experience and equipment, but also sending books, knowledge and materials, it is simply the captain of the transport team.

The materials for making the rock golem are now available in Zhenbei City, and the high-quality granite is sent directly to the quarry, and then those carver craftsmen are carved, and the process of making the rock golem is not too complicated, which is not too difficult for the two who already have experience in making clay golems.

The production of the rock golem can probably be divided into three parts, the first is to build the limb part, this step can be disassembled to complete, fortunately, Zhenbei City is now building a large number of carving craftsmen, and it is very reassuring to hand it over to them to carve Sulun.

The second part is to assemble the body structure, this step is like a splicing toy model, the rock golem is completely spliced, of course, when splicing, pay attention to the rune array inside the rock golem. The third part is spell activation, and this part requires Hathaway to cast spells.

Activate the Soul Center for the Rock Golem and activate the Construct Life.

In fact, Su Lun once considered whether it was possible to establish a golem production line in the future, as long as the production line started, it could be mass produced like an assembly line operation, and he was not the first to think about this idea, in the era of the Floating City, in addition to a large number of wizards living in each Floating City, there were also a large number of Golem Legions.

These Golem Legions are the assembly line production method, which is why the Arcanists of the Arcane Empire era can rely on the Golem Legion to press the demons who have always relied on crowd tactics to the ground and blast hammers. After all, the speed at which demons are born really can't keep up with the production speed of golems...

The height of a rock golem is about three meters, and it requires about three thousand catties of rock, and the weight will be slightly reduced after carving. Of course, there are also some large rock golems that can weigh several tons.

The main skill used to make the rock golem is carving, and it requires the use of magic oils and rune arrays, which are solved by those carvers in carving, and the rune arrays require Hathaway to carve.

After the runes are engraved, they are completely integrated into the body of the rock golem using materials such as gem powder and magic alloys. This step is also very important, as gem powder and magic alloy are arguably the most expensive things in the rock golem besides soul crystals.

Su Lun optimized and modified some parts of the Rock Golem according to the principle of mechanical control, and finally assembled the Rock Golem, after the assembly was completed, it was necessary to use the soul crystal to activate it, and cast a spell to activate and construct life.

Although it was all easy to say, Suren and Hathaway were busy working for five days to make a rock golem. The two of them traveled back and forth between the lord's castle and the laboratory almost every day, and it took three days just to engrave the runes and improve and optimize the energy transfer system, and it took two days to carve and assemble them combined.

The carving of all parts of the rock golem was carried out in strict accordance with the dimensions given by Su Lun, and the head, torso, and limbs were all made separately. This has the advantage that it is easy to replace even if the carving is broken, and all parts of the rock golem are made into standard parts, making it easier to assemble the golem.

And after making it into standard parts, these rock golems are very easy to repair, and if the part is broken, just replace it directly, as long as the soul center is not damaged, this golem will not die. This is also the preparation that Suren made in advance in order to try to build a golem factory in the future.

After the final assembly was completed, Hathaway picked up a medium-sized soul hedron and began to activate the golem, and cast a revitalized construct life. Like these steps, Su Lun hasn't figured out how to replace them, if they can't be solved, the Golem Factory in Zhenbei City needs to have a group of wizards who specialize in activating golems.

Powerful elemental energy erupted from Hathaway's body, followed by a throbbing of the soul, and the soul crystal turned into a purple soul energy that instantly merged into the body of the rock golem, and finally returned to peace. At the same time, the rock golem also moved in an instant.

"Ding, the host participates in the production of the golem, you have obtained more information on magic technology, and your magic technology experience has increased!"
