When she came out of the kitchen, it was already late, and Nangong Xu told her to go back and rest.
"Godfather and Godmother, I'll head back to the inn now," Yun Qingran said to Xiao Jie and Madam Xiao.
"Ranran, why don't you move in with us?" Yunxiao suggested.
The Xiao family owns numerous mansions in the capital, and they currently reside in a spacious mountain villa outside the city.
"Thank you for your kindness, Godfather, but I'd better not. The wedding delegation is staying at the post station, and as the chief envoy, I would need to stay with them. I'm afraid they might cause some trouble," Yun Qingran said with a smile.
"Alright, since you have work to do, your godmother and I won't make things difficult for you. It's getting late, you should go back now." Xiao Jie didn't force her.
"Yes, see you tomorrow, godfather and godmother, and see you tomorrow, Your Highness Xu." Yun Qingran waved to the three of them.
The three of them waved to her.
As Yun Qingran arrived outside the Xiao residence, a middle-aged man dressed in splendid attire, but in the style of a servant, approached her solicitously.
“Miss, this old servant was sent by the master to drive you. You can just call this old servant Lao Zhang.”
"Yes, thank you." Yun Qingran smiled faintly at him.
"Young Miss, please get in the carriage. This old servant will escort you back to the post station." Old Zhang took down the footstool.
"Okay, thank you for your trouble, Uncle Zhang." Yun Qingran nodded to him.
Hearing Yun Qingran call him Uncle Zhang, Old Zhang beamed. Not only was the young lady as beautiful as a fairy, but her personality was also so endearing. No wonder the master had adopted her as his goddaughter.
Uncle Zhang drove the carriage to take Yun Qingran to the post station. As soon as she got off the carriage, she saw two rows of elegantly dressed maids standing at the entrance of the post station. Needless to say, they must be maids from the Xiao family.
"Miss, this is someone the master sent to serve you. We're also looking for bodyguards," Uncle Zhang explained, seeing Yun Qingran's surprised expression.
"Uncle Zhang, please take her back. I don't need so many people to wait on me." Yun Qingran was embarrassed to say that. She brushed her teeth and washed her face as soon as she got up, and went to bed the same way at night. With her routine, she really didn't need so many people to wait on her.
“You are the eldest daughter of the Xiao family, so a few maids are not many. If you were in the old mansion, you would probably need twice as many,” Old Zhang said.
Yun Qingran: ?(????????)??????
"Old Zhang, but I really don't need so many people to serve me, and it's not convenient for them to stay at the post station. You should take them back with you." Yun Qingran looked at Old Zhang pleadingly.
"Alright, Miss, this old servant will obey your orders." After saying that, Old Zhang went forward to tell the two rows of maids to go back.
After watching the maid leave, Yun Qingran breathed a sigh of relief and walked into the post station.
"Master, Master, what happened? Why did the Xiao family send so many maids over, saying they were here to serve you?" As soon as she entered the post station, Green Immortal rushed towards her, asking gossipy questions.
“Yes, Xiao Jie and his wife have recognized me as their goddaughter.” Yun Qingran nodded smugly.
"What?! Xiao Jie and his wife have recognized you as their goddaughter!" Green Immortal was utterly shocked.
The social hierarchy is: scholars, farmers, artisans, and merchants. Merchants are the lowest in social standing. Although Xiao Jie is the lowest of the low among merchants, being the richest man is different from being an ordinary merchant. Moreover, Xiao Jie only has one child, and that child is mentally challenged.
“Yes, that’s right.” Yun Qingran nodded smugly as always.
"Did they give you any gifts or anything?" Green Immortal rubbed his hands together, looking at her intently.
“Yes, they gave me ten million taels of silver notes from my godfather, and my godmother gave me a money exchange.” Yun Qingran patted her small bag.
"What?! A thousand taels of silver notes, and a money exchange?" Green Immortal's envious tears streamed down his face.
"Hmm~" Yun Qingran was in a great mood.
"Ranran, go ask Mr. Xiao and his wife if they need another son. If they don't, do you need one? I'll recognize you as their mother and make you their grandson." Green Immortal looked at her intently.
Yun Qingran: ...
"Green Immortal, don't worry, you're my disciple, I won't let you go hungry. From now on, I'll cover all your expenses for alchemy," Yun Qingran said generously, hugging Green Immortal's neck.
Green Immortal wasn't really greedy; it was just that making medicine was incredibly expensive.
Studying medicine has always been expensive.
"Really?" Green Immortal looked at her with shining eyes.
"Of course it's true, but you have to give me half of the medicine you refine, and I'll have half the equity in the new medicine formula you develop. Hehe~" Yun Qingran smiled, revealing her white teeth.
"You shrewd merchant!" Green Immortal rolled his eyes at her; his sincere feelings had ultimately been misplaced!
"Oh dear, think about how much of the pills you refined when you were working illegally in Demon Valley, how much did Demon Valley give you?" Yun Qingran shook Green Immortal's shoulder.
Green Immortal raised his head and recalled his days in Demon Valley. Almost all the pills he refined were taken away by the valley. Sometimes, even if he secretly kept a few, the High Priest would send people to search and take them away. He was truly exasperated.
If you calculate it this way, splitting it 50/50 with the master doesn't seem so bad!
"Master, from now on, I'll give you half of all the pills I refine, and half of the equity in any new medicinal formulas I develop," Green Immortal said happily to Yun Qingran.
"Great job!" Yun Qingran praised him.
Green Immortal was so flattered by her that he was completely overwhelmed!
"By the way, Master, have you found any clues about Xiao Shi?" asked the Green Immortal.
Yun Qingran recounted the events of the day to Green Immortal.
"Wait, you're saying the skeleton is incomplete because it was corroded by sulfuric acid?" Green Immortal called out to her when she mentioned sulfuric acid.
“Yes,” Yun Qingran nodded. “Sulfuric acid is a highly corrosive substance.”
"Master, do you know how it was made?" asked the Green Immortal.
"The method for refining sulfuric acid is not difficult. Put ferrous sulfate and rice vinegar in a clay pot, cover it, and calcine it on a charcoal stove. When the ferrous sulfate melts, stir it evenly with a bamboo stick to fully mix the alum and vinegar. Heat it again and calcine until it turns completely crimson. Take it out and let it cool, and that is sulfuric acid," Yun Qingran replied.
After hearing Yun Qingran's words, Green Immortal looked at her in disbelief.
"What's wrong? Is there a problem?" Yun Qingran asked him, puzzled.
"Master, how do you know how to make green vitriol oil?" Green Immortal was extremely surprised.
After all, this was the first thing he knew how to refine, and the method for refining green vitriol oil was known only to him and the people in the Demon Valley; it had not been passed on to outsiders.
"I discovered it by chance," Yun Qingran said, touching her nose.
Actually, this was written in a chemistry tutoring and knowledge expansion book. Her family is a family of traditional Chinese medicine practitioners, and her grandfather had also told her about it. After seeing and hearing it, she naturally remembered it.
"Green Immortal, judging from your tone, you can also make sulfuric acid?" Yun Qingran asked Green Immortal.
"Master, the sulfuric acid you mentioned should be the same as the ferrous sulfate oil I spoke of, both made primarily from ferrous sulfate. I do indeed know how to make sulfuric acid; in fact, I was the first person to successfully produce it," said Green Immortal.
