Homemade sulfur

How to make it

Can sulfur be made

It has to be admitted, An Xue Tang's words left everyone present dumbfounded, completely unable to understand what she meant.

Sulfur is found by healers at special mountain passes, which An Xue Tang refers to as "craters."

They had never heard of sulfur being made.

An Xue Tang knew they were very curious about how to make sulfur, but she didn't want to explain too much right now. She would arrange for the people from Xuntang Valley to handle the production of sulfur, but honestly, it would also take some time.

Ancient people could only find natural sulfur, but as a modern person from the 21st century, she naturally had some more methods than they did.

Since natural sulfur cannot be obtained, she made it from pyrite.

There are still sulfur deposits in this era, but people of this time lack the technology, so they have no idea that combining pyrite and coke in a limited-air environment can produce sulfur.

She knew this technology. Now, all that was needed was to secretly find a sulfur mine and then secretly send people to produce sulfur from it.

This technology cannot fall into the hands of others, so this must be carried out with extreme caution.

Moreover, during this period, she also needs to ask people for help with some things they are currently unable to do themselves.

For example, she would try to gather as much charcoal and potassium nitrate as possible from the market.

Ancient potassium nitrate was actually quite easy to obtain, but even then she had to stockpile it, lest something like the sulfur incident happen again.

But she couldn't let the people around her prepare these things. Right now, she needed someone who seemed completely unrelated to her.

This person racked their brains, and all Xue Tang could think of was Mo Rui.

Morey...one of the few people she met when she first crossed over.

This man named Mo Rui had tuberculosis. At first, Qin Junchen didn't believe in her medical skills and insisted on giving her money to treat this man with tuberculosis. At the time, she thought that if it weren't for his tuberculosis, this Mo Rui might have lived a very good life.

He is a man of thought, courage, and most importantly, an invaluable kind heart.

After much deliberation, An Xue Tang decided to return to that place and find Mo Rui. She would offer him a potion that could prolong his life in exchange for his help in stockpiling charcoal and potassium nitrate.

After making the arrangements, An Xuetang was about to leave immediately. However, the next morning, the emperor's men arrived as expected, and the troops from Ancheng and Yangcheng had been withdrawn.

After the eunuch who delivered the imperial decree finished his duty, he wanted to visit the camp.

An Xuetang narrowed her eyes, crossing her arms. "Liu Gonggong, I didn't expect that even a castrated man like you would be interested in the affairs of the military camp Since you're so interested, why didn't you enlist as a soldier back then instead of emasculating yourself to become an eunuch"

"!"

Mr. Liu, upon hearing An Xuetang's words, almost fainted from anger. His whole body trembled slightly. After a moment of composure, he spoke:

"The Northern Border Princess is truly joking. Our family isn't suited for the battlefield. We simply have a deep respect for soldiers, after all, they risk their lives to protect us common folk."

It has to be admitted, this is quite capable, like an eunuch by the emperor's side. Even though he probably wants to tear An Xue Tang apart right now, he can still say this with composure.

An Xuetang narrowed her eyes and smiled, "Then Liu Gonggong should be more respectful. There's no need to go in and take a look. Otherwise, I'm afraid the big guys inside would frighten Liu Gonggong."

"Master Liu is a close confidante of the Emperor. If we frighten Master Liu, the consequences would be dire and we wouldn't be able to take responsibility."

Liu Gonggong is certainly acting under the Emperor's orders to investigate the Northern Border Garrison, so naturally he wouldn't give up now.

No matter what An Xuetang said, he just wouldn't leave until he had a look.

Ann Xue Tang curved her lips into a smile, her eyes holding an unreadable meaning as she looked at Yun Yi. She spoke slowly:

"Yun Yi, since Master Liu wants to have a look, then bring him in. And make sure you take him to see every tent where weapons are stored, otherwise there's nothing to see."

Yun Yi narrowed his eyes, a smirk playing on his lips. "Yes."

Lao Liu felt that something was fishy, but before he could react, Yun Yiang scooped him up by the collar like a chick and dragged him towards the military camp.

Liu Gonggong's feet left the ground. He was startled by Yun Yi's rude behavior and his face turned pale, "Yun...Yun Yi General, our family...we can walk ourselves."

Yun Yi acted as if he hadn't heard a thing. Though he was missing an arm, he effortlessly lifted up Liu Gonggong with one hand.

Thus, Liu Gonggong was led into the camp by Yun with a flick of his sleeve.

Yun Yi's lips curled into a faint smile as he tossed Liu Gonggong into one of the tents.

Before Liu Gonggong could make out what was inside the tent, a roar of a tiger echoed through the air. Immediately after, the tiger charged towards Liu Gonggong and bit him on his calf.

Because he was under orders, the tiger only bit him without killing him outright.

But even though he was just bitten, Liu Gonggong was so scared that he peed his pants, extremely embarrassed.

Yun Yi called over two soldiers, dragged Liu Gonggong out, and then continued to drag him to another tent. There, a tiger was still guarding the entrance.

Mr. Liu was so scared by the tiger that he almost fainted several times.

But when he fainted, Yun immediately had someone wake him up and continued to take him around the tiger's camp. After several such trips, Liu Gonggong felt like he was about to die.

An Xue Tang and Mo Jun Yi were preparing things for Yun Yi's surgery. When Yun Yi came in to report on Liu Gonggong's condition, the two of them couldn't stop smiling.

After laughing enough, An Xue Tang asked Yun Yi to prepare. She personally took the knife and treated the dead flesh at Yun Yi's severed arm. Although his arm could not be reattached, the wound still needed to be properly treated.

An Xuetang spent more than two hours carefully treating the wound on Yun Yi's broken arm. After instructing the military physicians to change his dressing regularly, she left with Mo Junyi.

Before the two men could return to their tents, Liu Gonggong, his hair disheveled and resembling a ghost, suddenly ran towards them.

Behind him followed several tigers. The tigers didn't bite him, but they just wanted to chase him.

This scene looks like a game of "Eagle catching chickens".

An Xuetang looked at this comical scene, the corner of her mouth couldn't help but curl up in a smirk.

Mr. Liu couldn't hold on any longer, he saw An Xue Tang and cried out loudly, "Your Highness, Your Highness, save me!"

An Xuetang narrowed her eyes, just watching without intending to say anything.

Perhaps seeing that An Xuetang didn't want to save him, Liu Gonggong could only resort to his trump card, "Your Highness, please save me! My family knows where the Emperor has kept your mother. As long as you save my family, we will tell you anything."looking at Mo Yun Jing with a hint of confusion.Mo Yunjing didn't know what he was thinking about. His eyes dimmed, as if covered in a layer of ash. The depths of his black eyes, like ink, were filled...
