In an environment of precariousness and precariousness, no one thinks about long-term development plans.

Besides, the mountains and forests were originally the territory of the lords, and as long as the dwarves had a job and could eat, they didn't care what happened to their surroundings.

The mountains and forests, which are now full of greenery and life, are not so much a natural way of harmony between man and nature, but rather a concrete portrayal of low productivity.

What is the master worried about? Ninia didn't read Vincent's deep expression, nor did she want to see him worried, this time the lord didn't give a confident order, but instead consulted with the dwarves for a long time.

"It's too slow, it's too wasteful, it's too uncontrollable, it's too cumbersome," Vincent kept denying himself and others, "just like the previous firing of refractory bricks, even if you get the product at any cost, you can't use it."

At the end of the meeting, Vincent did not have an idea of how to start the project, and finally only finalized the plan of how to carry out coal preparation and coal blending.

The battle in the mine is almost over, and this is because there are more and more dead people in the cave, so the demon necromancer has been given the opportunity to summon the necromancer.

All kinds of resentful spirits are chasing everywhere with their pursuers, hiding is a dead end, and there are hunters waiting for rabbits everywhere when they run out, and the bandits are completely at the end of the road.

The mines where the coal was mined were completely controlled by the territorial army, and the dwarves brought the undead to get the coal that the lord needed overnight, and then put it on the light rail and transported it to the vicinity.

After small-scale coking experiments and simple laboratory distillation, Vincent and the craftsmen had a general understanding of the nature of local coal, and it can only be said that the results were mixed for coking.

Unfortunately, local coal is not the most suitable coking coal for direct ironmaking, but other types.

In order to let his subordinates intuitively see the results of the dry distillation of coal, Vincent used a set of glass instruments, and the once familiar equipment such as test tubes, catheters, beakers, alcohol blowtorches, and test tube racks made a shining appearance, which immediately attracted La Nina's attention.

However, he eventually asked La Nina to prepare a flame magic array, which she often experimented with herself.

The lord has the talent of an alchemist and the wisdom of the periodic table, so it is easy to play a dry distillation of coal.

"My lord, this coal produces a lot of flammable gas," Chief Mage La Nina asked curiously when she saw the gas coming out of the U-shaped nozzle on the table ignited and kept burning, "What kind of gas is this?"

"This is coking gas, which is a by-product of coal distillation, with a high combustion value, which can be used in blast furnaces, and can also be used for ordinary people's homes to make fires for cooking," Vincent stared at the flames that had been burning for a long time, and said lightly, "What a pity, my heart is very sad to think that so much coke gas has to be drained and wasted in vain, and cannot be burned in other facilities."

The volatile content of coal here is very high, and it cannot be said that it cannot be coke, but it is a waste of gas.

"It's amazing that coal can produce high temperatures, not just because of itself," La Niña lamented, "The humble stone is so magical, if it is constantly sealed and distilled like this, wouldn't it be a source of energy to get combustible gas?" It's magical......"

"First of all, these precious gases must be collected and transported to other places before they can be used," Vincent added, "and if there is nothing but problems in between, there are so many terrible gases that they can blow up all the castles into the sky."

La Niña subconsciously took a step back, revealing a look of trepidation.

"Master, what's in the tube under this cup?"

Unlike mages who don't go to battle, Ninia has no fear of such a gadget, and she stares curiously at the liquid that slowly accumulates under the U-shaped tube, and notices that the upper and lower layers are different colors.

"Transparent on it is a mixture of various benzene, benzene is a very useful substance, which can be used to make medicines, dyes, pesticides, etc.," Vincent approached her, pointing to the layered liquid inside, and whispered in the girl's ear, "and the explosives that blew up the golem, and benzene is also used, my toy, don't tell the Herodians."

Ninia's beautiful blue eyes widened, she really didn't expect the clear liquid in them to be so dangerous.

"The dark part below is coal tar, which is heavier than benzene, so it naturally settles. It is also a useful material for combustion, anti-corrosion coatings, and as an additive for many other new materials. What's more, it contains ammonia, do you remember what I said?"

"Huh? Oh...... Ammonia, that's ...... Hey? It's the strange substance that you say feeds people and kills people?"

"That's right, you're doing well......

I don't know if it was because the lord was too close, or because she was shocked by the use and power of the new material, Ninia's shoulders trembled slightly, and her beautiful face became a little ruddy.

"My lord, the rest of the coal in here should be the coke you want, right?"

La Nina's somewhat untimely voice suddenly interjected, sobering up Ninia, whose face was dripping.

"Yes, that's what I want, but not just a spoonful, it's a thousand pounds and a million pounds! Feed all my furnaces and get the resources that will allow people to live happily on this land."

"This ...... Isn't that all a good thing?" Ninia was infected by Vincent, and asked with a little nervousness and excitement, "I have obtained so many useful things, why don't you magnify this device a hundred times and get it directly?"

La Niña nodded, as expected, she had already thought of this.

"Look at how much magic power is used in this magic array?" Vincent pointed to the magic array and asked, "If you follow the original plan, you will need to install dozens of large ones in the coke kiln and burn them for ten days in a row?" How many magic stones are converted into magic stones?"

Fire magic is an efficient and clean way to ignite, and it is certainly the first choice for mages, and La Niña wonders why the lord doesn't put some in the refractory brick kiln.

"I'll tell you the unfortunate news that the amount of magic stones purchased in the territory has been large enough to attract the attention of the Herodians, and some ill-intentioned people are imposing sanctions and blockades on my territory to prevent me from easily obtaining the supply of magic stones."

Who is the ill-intentioned person, La Nina knew as soon as she heard it, and the flames that were originally controlled by her were instantly amplified several times, so an explosive sound sounded, and the test tube cracked.

"I'm sorry, I'm sorry, I'm so excited," La Nina explained apologetically, "I didn't know the territory was in such a difficult situation right now, and if my family's power was still there, I would definitely find a way to help you......

"It's not your fault, but I've had to pay attention to the use of magic stones and the output of mana." Vincent waved his hand and said, "The blockade is not good for both sides, but a small territory is no match for an unreasonable large country."

"In order to continue the construction, I had to think about stopping all kinds of high-consumption designs...... The news is conclusive, I have thought a lot in the past two days, but there is still no good way......

At this desperate moment, the closed door of the workshop was suddenly pushed open, and a figure swooped to Vincent's side.
