It's hard for my elder sister. I rely on the mountains to farm and pay off my debts.

After walking for more than half an hour, Song Zhi wiped the beads of sweat from her forehead and looked at the towering city wall.

Although the sun was already high in the sky, there were still many people queuing up to enter the city, including many caravans driving carts and transporting goods.

Qishui County is the only way to the grassland. Going north for another hundred miles, you will reach Anning County, the last town within the Great Wall. Outside Anning County, there is endless grassland.

Now that the world has been initially settled, the new emperor has signed a contract with the grassland royal court and implemented a policy of mutual trade in order to live in harmony with the people.

Qishui County is an important trade route leading to the heartland of the Central Plains, so there is an endless stream of caravans traveling to and from the county. Therefore, the inspections conducted by the officials outside the city are very strict.

As the team moved slowly, Song Zhi's attention was attracted from time to time by the guards on both sides of the city gate.

They wore big swords on their waists, had serious faces, and carefully checked every person entering the city.

Especially when a convoy needs to enter the city, in addition to verifying identity information, even the cargo on the vehicle must be checked one by one.

Finally, it was the turn of the grandparents and grandchildren.

The gatekeeper looked the two men up and down, then asked them about their purpose as a matter of routine.

Wu hurriedly paid two cents for the entrance fee and explained her purpose.

An officer came forward and rummaged through the two men's backpacks. Seeing that there was nothing wrong, he collected two cents as an entrance fee, waved his hand, and the two men entered the city.

Unlike the low yellow mud houses outside the city, the moment you pass through the city gate, you step from the dilapidated world outside the city into another completely different world.

The streets in the city are spacious and clean, with shops lining both sides and a wide variety of goods on display, which is dazzling.

There are crowds of people and traffic, creating a prosperous scene.

Song Zhi looked at the bustling county town and breathed a sigh of relief.

She followed the flow of people into the city and walked into the city. The aroma of various foods lingered in her nose, making her hungry.

Just as she was thinking about whether to stop and ask passers-by where the clinic was, the eye-catching plaque of Renxin Hall not far away came into her sight.

Song Zhi paused, turned around and said to Grandma, "Grandma, please wait for me on the street. I'll go to the clinic up ahead and ask if they sell herbal medicine."

Mrs. Wu looked at the glittering golden sign, feeling somewhat timid. She hesitated and said, "Should we change to another clinic? I heard from the villagers that the medicine there is very expensive!"

"It's okay, I'll go ask. We don't buy medicine from him, so what's there to be afraid of!" After saying that, he walked towards Renxin Hall.

There were people in elegant clothes coming in and out of the drugstore from time to time. It seemed that the doctor in this clinic must be quite capable.

I just don't know if the pharmacy will accept her medicinal materials.

Song Zhi followed the patients seeking treatment into the clinic, and immediately a little pharmacist came up to her and asked her what was wrong with her.

Song Zhi calmly stated her intention. The little medicine boy's expression remained unchanged after hearing this. He only said apologetically, "I'm sorry, ma'am, but we don't accept individual medicinal herbs from retail customers."

When Song Zhi heard the little medicine boy say this, she seemed to have expected it. She said, "Sorry to bother you!" and turned away.

After the man left, the little medicine boy returned to the counter and reported the matter to the shopkeeper who was currently working on an abacus with his head down.

After hearing this, the shopkeeper didn't even raise his head, still fiddling with the abacus in his hand, not taking the matter seriously at all.

In the eyes of the shopkeeper, what could ordinary people know about medicinal herbs? Not to mention that their shop has no shortage of northern medicinal herbs, just the labor and time required to pick them out is a waste of time.

Song Zhi returned to Wu's side and shook her head, "This shop doesn't accept retail medicinal herbs. Let's go ask somewhere else!"

Mrs. Wu was slightly disappointed, but nodded repeatedly. There were two pharmacies in the city, so it wouldn't be that neither of them would accept the medicine.

Because there were many inns and restaurants on this street and most of the caravans came and went, Song Zhi didn't walk far before she saw a clinic.

This time, when Song Zhi asked if they could buy the herbs, the other party was willing to accept them, but the price they offered was ridiculously cheap.

The basket of three nine-leaf clover she carried weighed at least thirty pounds, and the other party directly offered her three cents.

Do you think she is a country woman who has never seen the world and you want to send her away with just three cents?

Song Zhi sneered in her heart, but she still restrained herself and said, "Boss, even thirty kilograms of wild vegetables cost more than three cents, right? Can you raise the price a little?"

The shopkeeper waved his hand unmoved, "We don't lack this kind of herb here. If you want to sell it, it's three cents. If you don't want to sell it, please go back!"

Song Zhi didn't want to listen to the shopkeeper's nonsense, so there was no need to deal with him anymore. She turned around and left the pharmacy.

This time, Mrs. Wu was standing at the door of the medicine shop. Seeing her granddaughter walk out without looking back, she hurriedly followed her and asked worriedly, "Aren't you going to ask the price of the herbs in my basket?"

Song Zhi shook her head. "Grandma, he's deliberately trying to lower the price. There's no need for us to waste our breath on this."

"I remember I went to the West City Clinic to see a doctor before. Grandma, let's not hang around in the East City anymore. Let's go to the West City to see a doctor."

Wu thought about it and nodded, "Okay, let's go to the west of the city. I'll just go to the streets and sell the eggs I have!"

The grandfather and grandson agreed not to walk around the busy streets and turn directly to the west of the city.

Unlike the east part of the city which is mostly lined with high-rise buildings and shops, the west part of the city is mostly composed of low-rise residential houses.

Most of the shops on the street are rice, flour, grain and oil shops, providing daily necessities for the people living nearby.

Because they wanted to sell eggs, the grandparents and grandchildren deliberately walked through the alleys. When they passed by houses with open doors, Song Zhi would smile and talk to them, asking if they wanted to buy eggs.

Eggs are not easy to sell outside the city, but they are easy to sell inside the city.

Song Zhi didn't have to ask, and the two families living in the alley saw that the eggs in their baskets were quite large, so they each took half and emptied all the eggs.

Wu held the twenty-two copper coins she had just received in her pocket, and finally a rare smile appeared on her face.

After walking out of the alley and along the main street for about half a minute, Song Zhi saw the pharmacy where she had brought her younger brother to see a doctor.

In her impression, the doctor in this pharmacy was quite easy to talk to, so Song Zhi decided to go in and give it a try.

As the weather warmed up, only a few patients came to the pharmacy to get medicine. After the grandparents and grandchildren entered, Song Zhi asked her grandmother to take off the backpack first.

After the shopkeeper finished dispensing the medicine, he looked at the two men and asked, "Which of you feels unwell?"

This time, Song Zhi directly displayed the two baskets of medicinal herbs in front of the shopkeeper. She smiled and said, "Shopkeeper, do you accept these herbs?"

Shopkeeper Li originally didn't want to accept it. At that time, few people could recognize all the medicinal herbs, and he was unwilling to spend time and effort to select them himself.

But when he saw the cleanly sorted herbs in the basket, the words of refusal that were about to come out of his mouth were swallowed back.
