<h4>Chapter 644: Saltpeter Ranch & Demon Farming</h4>


    Given Henry Worden’s perception, he had heard what the yers were saying.


    Even though each word was understandable on its own, it became iprehensible after putting it together. There were even transliterated words that he had never heard before, simr to technical terms.


    As a saint, he identally discovered that there was still knowledge he did not understand. It was undoubtedly quite a novel and rare experience.


    The yers immediately became serious and stopped the banter after seeing Saint Henry again. They addressed his question respectfully.


    Lin Yiyi felt troubled. “About that…”


    She wasn’t sure how to exin to the saint.


    It felt like exining game terms to grandparents.


    That’s what they called the age gap, right?


    At this moment, Jiu Er was the first to speak up.


    “May we touch his body?”


    “…Touch the body? Jacob’s?”


    Saint was stunned momentarily, “But, does he have a corpse?”


    Afterward, Henry Worden quickly reacted, “Oh… are you looking for spoils of battle?


    “That’s no problem. I can be sure there are no other Gold Rank Fallens in this town. You should be more careful and vignt when searching. With yourbat strength, there shouldn’t be any major problems.”


    The saint was not that interested in what the yers were discussing previously.


    Since the yers diverted the topic, he couldn’t be bothered to circle back to it.


    Instead, he patiently exined to the yers, “Follow this road to the entrance of a barbershop. Then, turn into the small alley on the left and go straight until you reach the end, then take a right turn. That will lead you to the back of the ‘Saltpeter Ranch’.”


    “By the way…” Suuankou asked curiously, “Why is this ce called Saltpeter Ranch?”


    As the increasingly distinct smell of sulfur reached his nose and he saw a menacing sorcerer approaching, Henry instinctively took a half-step back, pursing his lips with a hint of caution.


    This surprised Suuankou a bit.


    So, my intimidation works on a seemingly immortal saint like this?


    As expected of the School of Destruction, it’s cool!


    “This has something to do with your Destruction School.” The saint said slowly, “You may not know that the gunpowder used in firearms contains a certain proportion of nitrate.”


    “Well, I know that.” Suuankou’s expression was a bitplicated.


    He never imagined that one day he would be educated by someone from another world on elementary chemistry.


    It took great effort to resist the urge to bombard the saint with questions and delve into a discussion about potassium nitrate. After all, he was still a college student and hadn’tpletely forgotten the content of the college entrance examination.


    However, Suuankou thought about it. If he wanted to pretend to be a time traveler, he should only act cool among his peers.


    “One of the main sources of nitrate is saltpeter. However, saltpeter must be processed before it can be used for tanning leather or manufacturing gunpowder, dyes, and other chemicalpounds.”


    The saint said seriously, “Fallen are those who have beenpletely consumed by the curse and turned into demons. Their fresh blood can trigger explosions after mixing with fermenting urine. The mixture can be used to produce high-purity saltpeter powder that ismonly used as gunpowder. A Destruction Wizard discovered it. The recipe has been optimized over several generations.


    “In other words, domesticated demons are worth breeding. I know that several underground cities engage in saltpeter production using this method.”


    “After all,pared with purification from nitrate mines, urine, and blood are cheaper and inexhaustible. The so-called Saltpeter Ranch actually means demons breeding ground.”


    “I see.” Suuankou nodded.


    There were so many absurdities in this conversation, Suuankou felt like he had a bellyful of sarcasm that he couldn’t express.


    “Well, then I’ll take my leave,” the young man, covered in wounds, saw the momentary silence among the group that didn’t initiate any further conversation. He smiled faintly at everyone and nodded, “Until we meet again, everyone, if fate allows.”


    Then, he walked in another direction.


    Suuankou, together with the other three yers, watched his figure disappear.


    “I feel like you’re choking on something.” Lin Yiyiined in a low voice.


    Suuankou nodded silently.


    In fact, he was still somewhat wary of this saint.


    Even though the saint seems friendly, he might be in a different stance in the future.


    In that case, all the boasting he had done with that guy would have only made future challenges more difficult. If he had identally unlocked something crazy and messed up, he would have still been the one dealing with the consequences.


    Unlike his sister, Suuankou had always been wary and kept his distance from others.


    Having said that, he suddenly had an idea.


    Coal and natural gas were avable. The development and awareness of this technology were not low.


    Even the value of coal areas and gas fields was greater than the value of mining areas. Despite having clean alternative resources like ck Fire and Green Fire, which were simr to “crude oil,” strategic reserves of coal mines were still crucial.


    One of the Alteration Magic raw materials of ck Fire was the stored natural gas, and the Swamp’s ck Tower had a precious natural gas well at the bottom. It was highly valued that no yers had ever entered it. Green Fire was much simpler. It was a safe resource after the ck Fire underwent two cycles of alteration magic. The ck Fire used for Green Fire conversion was specially treated and mixed with stabilizers to prevent explosions.


    Although they looked simr, yers who had knowledge of this aspect had already tested it. ck Fire and Green Fire were not crude oil or natural gas liquids. Theirbustion efficiency was simply not what civilization at this stage could utilize.


    It could be said that without the two Alteration Magic products, ck Fire and Green Fire, the civilization of this steam-age should not have existed at all.


    The ck Fire and Green Fire were the way wizards in this world used natural gas. The form was unknown. However, the locals employed special forms and Alteration Magic to transform natural gas into ck Fire and Green Fire, which had rtively stable properties and incrediblebustion efficiency.


    The former contained higher and more intense energy, while thetter was more gentle and controble. Since Green Fire was an “absolutely non-explosive” me, the temperature was low, and it would not easily harm the children.


    Its price was also quite low. Tower Master Hugo made this decision. He made the recipe of Green Fire public. An Alteration Wizard of Bronze Rank could stably produce enough Green Fire for a town. Moreover, the consumption of Green Fire for cooking for the whole city was only up to three to four barrels of ck Fire per day.


    Afterward, Master Benjamin further optimized the form. As long as three Wizard Apprentices worked together, they could operate the Alteration Magic to convert ck Fire to Green Fire. The amount of ck Fire consumed was reduced to one-third. If there was no ck Fire, coal or charcoal could also be used as substitutes, which was much more efficient than directly burning them to light fire.


    Benjamin did fulfill the promise he once made to Evelyn. He made it possible for every household to lightmps and cook food.


    Even the urban residents of the Noah Kingdom had gradually developed the habit of drinking hot water. This new culture was born because the burning cost was getting lower and lower.


    Before that, wanting to drink boiled water was a luxury in this world.


    Leaving aside the ck Fire, the “Green Fire” technology was even more advanced than the Earth. There was no crude oil in this world, which made the yers doubt whether the knowledge on Earth could be used normally here.


    However, this would not be a problem after Annan seeded to the throne.


    The yers only need to provide the direction and let His Majesty Annan send schrs to experiment.


    The yers wouldn’t bother exining how they came up with the technology since there were so many excuses in their heads already.


    Thinking of this, Suankou had an idea.


    He realized that as a Destruction Wizard, he seemed to have prepared too little dangerous items with him.


    “You guys go first. I need to take my luggage.” Suuankou told hispanions, “I’ll buy some spell-casting materials first. I’ll travel light, and I’ll be able to catch up with you soon.”


    “Okay, then make haste.” Lin Yiyi quickly responded.
