"Iron and salt?" Zu'an was taken aback. This was a cultivation world! Even if you weren't running a spirit stone mine, you should at least be raising some magical beasts. Why were you dealing with such... such common things?

As if guessing what he was thinking, Cheng Shouping explained, "Young master, don't underestimate these two things. They can bring huge profits to the family. Our Chu family is so rich that it's comparable to a country because of these two things. You have to know that only a few people in this world can cultivate. Most people are like us, unable to feel the existence of the primordial energy of heaven and earth, and can only live an ordinary life. Salt and iron are necessities for our lives."

Zuan curled his lip: "What do you mean by 'us'? Don't lump me in with ordinary people like you. I can cultivate."

Cheng Shouping blinked at him, looking hesitant, thinking to himself that this son-in-law was indeed as they said, all talk and no action.

But it's alright, he's still the son-in-law, I'll definitely help him win the young lady's heart. They say it's easy to add flowers to brocade, but difficult to offer charcoal in the snow. I'll help him when he's at his lowest point, and then I'll naturally become his confidant, and my status will rise accordingly. Maybe I can even get together with Xue'er... hehehe~

"What are you grinning about?" Zu'an slapped him on the head. "Which way does that Doctor Ji live?"

Cheng Shouping adjusted the two buns on her head: "Young master, could you please stop hitting my head in the future? These buns are hard to comb."

Zu'an looked at the two char siu bao-like things on his head and was speechless: "Alright, alright, lead the way." He had a general understanding of the situation of the Chu family. He could only investigate whoever wanted to harm him later. The most urgent thing was to solve the problem of his own happiness.

“Young Master, I don’t think you need to go see Doctor Ji anymore.” Cheng Shouping jogged up to catch up.

"Why?" Zu'an asked, puzzled.

Cheng Shouping explained, "Because this Divine Physician Ji has established a rule that if you want to see him for treatment, you have to pay a registration fee of one hundred taels of silver."

"A hundred taels of silver? Just for registering? Does he have diamonds in his pocket?" From what he had seen and heard in the past two days, he had a general understanding of the currency system of this world. In fact, it was similar to that of ancient China. One thousand copper coins were equal to one tael of silver, and one tael of gold was equal to ten taels of silver. Above gold, there was another hard currency, which was Yuan Stone. However, Yuan Stone was often priced but not available, and its specific price was difficult to quantify.

However, the units of measurement in this world are not like those in ancient China, but are similar to those in the modern world. One tael is equal to 50 grams. At the same time, silver has not been over-exploited and devalued. One tael of silver has a purchasing power of about 1,800 RMB. One hundred taels is equivalent to RMB, and that's just for registration. No wonder he shouted it.

Zu An thought for a moment and put his arm around Cheng Shouping's shoulder: "Little Pingping, you see, your son-in-law is a little short of money right now. Could you lend me some to tide me over? I'll pay you back double when I have the money."

Cheng Shouping quietly covered the purse at his waist: "Young master, you are the master and I am the servant. If even the master has no money, how could I, the servant, possibly have any?"

Zuan took in his little actions, but didn't care. Even if he had some silver, he couldn't possibly have 100 taels of silver. "By the way, where are there places that sell slaves around Mingyue City?"

“Young master, you mean the brokerage firm, right? There are special places in the city where nobles can trade servants and maids, each worth anywhere from a few taels to tens of taels…” Cheng Shouping paused mid-sentence, then couldn’t help but glance back at Zu An, swallowing hard. “Young master, you’re not thinking of selling me, are you?”

Zu An's expression turned serious: "How could that be? Do you think I'm that kind of person?"

In his heart, however, he was calculating that this guy wouldn't be worth much money even if he were sold, and since he was a member of the Duke's mansion, he might not be able to sell him.

Despite receiving his assurance, Cheng Shouping still felt a chill run down his spine and hurriedly said, "Young master, there is actually another way. Besides the 100 taels of silver, if you can help Doctor Ji complete a task, you can also receive his treatment."

Zuan felt relieved and slapped him on the shoulder: "Why didn't you say so earlier? I almost sold you out."

Cheng Shouping: "..."

Watching his son-in-law's enthusiastic departure, Cheng Shouping hesitated, knowing that the tasks that Doctor Ji had undertaken were not something ordinary people could accomplish. However, he was also worried about being sold off, so he ultimately did not tell the other party the truth.

Before long, the two arrived near a house. Looking at the sea of ​​people in front of them, Zu An swallowed hard: "Why are there so many people?"

Cheng Shouping chuckled awkwardly, "Didn't I just tell the young master? Doctor Ji's place always has this many people."

Zu An thought of those top-tier hospital specialist appointments in his previous life, which were so difficult to book even ten days or half a month in advance, let alone those famous doctors. This situation of the miracle doctor was indeed normal.

Wait a minute, isn't the registration fee supposed to be one hundred taels of silver? Are people in this world all this rich? But look at all these people surrounded by layers upon layers of people, and their clothes aren't made of very good material. They don't look like they're extremely wealthy.

"Where is Miss Ji? Why isn't Miss Ji here?" Someone in the crowd shouted, instantly causing a commotion.

"Yes, we want to see Miss Ji."

...

Zu An was taken aback and turned to look at Cheng Shouping: "The Divine Doctor Ji you're talking about is a woman?"
