After replying, the little eunuch dragged the person away, grumbling as he went, "Whatever the master says goes, why did you ask?"

Two hours later, a deep tunnel was dug out inside the Fu Shuang Palace, containing a large amount of saltpeter.

Wow, this really is a saltpeter-producing area!

"Alright, you can all leave now."

Yun Duoduo gestured for everyone to leave the courtyard.

"Without my order, do not let anyone in."

Ah Xiang and Xiao Liuzi glanced at Yun Duoduo with concern, and Yun Duoduo waved to them.

"Don't worry, I know what I'm doing."

Yun Duoduo carried saltpeter into the house by herself, and also took out a lot of raw materials from the furnace in the backyard where she usually refined pills.

Inside the room, she was adjusting the settings and making adjustments. She had shooed everyone out. If it exploded and injured her, that would be one thing, but if it harmed others, she would regret it terribly.

Since there was no weighing instrument, Yun Duoduo carefully tested it countless times.

From the moon rising above the willow branches to the first light of dawn in the sky.

She cautiously examined the materials before her, pondering the reaction. The chemical equation for making gunpowder from saltpeter is: 2KNO3 + S + 3C → (ignition) K2S + X↑ + 3CO2↑

[It requires adjusting the mixing ratio of saltpeter, sulfur, charcoal, and auxiliary materials such as arsenic compounds and oils.]

Fortunately, I often practice alchemy in the backyard, so I have a fairly complete supply of raw materials.

Finally, with a loud explosion, she revealed a satisfied smile.

When she emerged from the house, covered in dust and dirt, it was already the next morning.

"Princess!"

"Princess!"

Ah Xiang and Xiao Liu Zi had been waiting outside, and they only breathed a sigh of relief when they saw Yun Duo Duo come out.

Yun Duoduo was covered in black soot and had an afro. Ah Xiang quickly took out a handkerchief to wipe her face: "Princess, are you injured anywhere?"

Yun Duoduo shook her head: "You've been outside, watching over me the whole time?"

Ah Xiang and Xiao Liu nodded.

"You should all go and rest too."

Yun Duoduo felt a mix of emotions. She knew that A Xiang and Xiao Liu Zi were the most loyal and the best to her.

"This servant will go and prepare bath water for the princess."

Ah Xiang gestured for Xiao Liu to stay and keep Yun Duoduo company. She turned and quickly left to prepare bathwater and clean clothes.

...

For the next two or three days, Yun Duoduo was busy in Fu Shuang Palace, making poisons and explosives to deal with the enemy, as well as wound medicine and tonics for her soldiers.

"Princess, you said all this, gunpowder?"

Ah Xiang looked at the two large boxes placed in the side hall of Fu Shuang Palace and asked in confusion.

Yun Duoduo nodded: "Yes! I put in a lot of effort to make these things!"

"Aunt Xiang, these two boxes must not get wet or exposed to open flame. Someone must guard them day and night!"

Ah Xiang nodded. She understood that if the gunpowder, which the princess had worked so hard to make, got wet, it would be unusable.

If it comes into contact with an open flame...

Then she, the princess, and everyone else in the Fu Shuang Palace would all perish here with a loud "bang".

"Princess, rest assured, I will have a few capable and reliable people from Fu Shuang Palace guarding the place."

Yun Duoduo knew that entrusting this matter to A Xiang would definitely be reliable, so she stopped thinking about the gunpowder and instead pushed over a wooden box, filling it with bottles of medicine and powder.

"Princess, are these medicines for treating injuries?"

Ah Xiang looked at the various medicine bottles inside the box.

"almost."

"These are the Huoxiang Zhengqi Pills, Huoxiang Zhengqi Water, and Huoxiang Oil that I made," Yun Duoduo said, pointing to several brownish-yellow bottles.

"It can prevent and treat heatstroke and diarrhea."

"And these are pills made with angelica and cardamom."

"These are medicated oils, safflower oil, Tiger Balm, and wound medicine. They can refresh the mind and treat external injuries."

"For the ingredients that are more susceptible to light reaction, I used dark-colored bottles. For the more volatile ingredients, I sealed them with very tight corks."

As Yun Duoduo spoke, she placed the bottles and jars that had been scattered all over the backyard into the box and stacked them neatly.

Ah Xiang looked at Yun Duoduo with great heartache. She was such a small girl, yet she had done so much day and night.

"Princess, these things can be done by your servants. Why do it yourself?"

Yun Duoduo waved her hand: "These are all matters of life and death. Some herbs look very similar, and the dosage and ratio need to be strictly controlled. I really don't trust others to do it."

"Make a batch for urgent use first. I've already written the prescription. In a little while, send someone to the Imperial Medical Bureau and tell them to make it as soon as possible."

Ah Xiang nodded. She noticed an empty box in the side hall and asked Yun Duoduo, "Princess, what is this box?"

Yun Duoduo raised an eyebrow and smiled, then turned and called out to the next room, "Zhuangzhuang! It's your turn!"

"Sister Duo, I'm here!"

As soon as she finished speaking, Jin Zhuangzhuang came in carrying a large basket, swaying as he walked in. When A Xiang saw this, she quickly got up to help him.

"So heavy!"

"Sister Duo, Aunt Xiang, these are all poisons that I've been working on day and night to develop!"

Jin Zhuangzhuang deliberately dragged out the last syllable, keeping everyone in suspense.

"You little rascal!"

"Just tell me already, stop keeping me in suspense!"

Yun Duoduo patted Jin Zhuangzhuang on the shoulder.

"This is poison, this is arsenic, this is antiseptic, and there's also the intoxicating fragrance that travels a thousand miles, and the three-step carefree powder..."

Jin Zhuangzhuang proudly introduced her poison, while Yun Duoduo listened with great interest, occasionally taking out a bottle or two to look at and guess the ingredients.

Ah Xiang stayed far away, not daring to approach at all.

"A fragrance that can enthrall the soul for miles..." Jin Zhuangzhuang said leisurely.

"A fragrance that can enthrall the soul for miles..." Yun Duoduo murmured, repeating it over and over.

"This name is really quite interesting."

Yun Duoduo rolled her eyes, raised an eyebrow, and asked, "Is this 'Thousand Miles of Ecstasy' the same as 'Entwined Love Threads' and 'Sending Spring Breeze'?"

Jin Zhuangzhuang waved his finger and said mysteriously, "This is a modified version of sleeping potion. It can make the poisoned person feel weak all over, and also give them a tingling sensation, just like..."

Jin Zhuangzhuang gave Yun Duoduo a knowing look, and Yun Duoduo looked at Jin Zhuangzhuang with surprise, who remained calm and composed.

When did this child become so knowledgeable?

Could it be that she secretly read all the erotic novels I hid under the bed?!

If Jinzhi's brother knew about this, would he think that I led Jin Zhuangzhuang astray?

"Are there any antidotes for these poisons?"
