Song Si and Song Wanyue looked up and saw a student in their twenties wearing brand new blue cotton clothes.

The man came over and bowed to Song Si, "You are willing to call me at my brother, I hope you can forgive me. I just heard from my sister that mint oil is, but I don't know how much it costs?"

Song Si was about to answer, but Song Wanyue took the lead in answering, "One Hundred and Fifty Texts."

The man frowned slightly. One hundred and fifty cents were not much, but not much.

He hesitated for a moment and spoke with a little embarrassedly, "Can I let me take a look first?"

"Yes, you wait."

Song Wanyue turned around and went into the room to get a bottle of mint oil, opened the bottle plug, and signaled the man to spread his hands. She dripped two drops into his palm, "You just dip your fingers and apply them on your temples."

The man did as he did, and the moment he smeared on, a cool feeling came, and his restless mood seemed to suddenly calm down. He said without hesitation, "I want it, you two, wait a moment, I'll get you money."

He has already taken the exam twice. Every time he takes the exam, he becomes restless and dizzy on the first day, so he loses his standards. With peppermint oil, he can perform normally.

He turned around and hurriedly went downstairs. After a while, he brought 150 cents and handed them to Song Wanyue.

Song Wanyue didn't ask for it all, leaving only one hundred documents, "You are the first customer to come to the city. I'll give you some discounts, only the capital is 100 documents."

The man was overjoyed, thanked him again and again, and took the mint oil to the innermost room on the second floor.

Song Si followed Song Wanyue back to the house with a brush. Song Wanyue just asked for 150 cents, but he was wondering, saying that he was good at home and selling it for 100 cents. Why did Yue'er suddenly change her mind? It turned out that she wanted to earn another favor.

"Yue'er, you're getting smarter."

Song Si sincerely praised it - whether it was asking Mr. Sun to buy pills without any trace, or the student who took the initiative to buy mint oil just now, if he put it on him, he would never have thought of such a good idea.

“That’s…”

Yue'er raised her little face proudly, "I don't even look at whose sister I am. My elder brother is the one who wants to be the top scholar. How can my sister be bad?"

Song Siren couldn't help laughing, and unconsciously raised her hand and touched her head, teasing her, "In order for you to show off in front of others in the future, my brother has to work hard to get back as the top scorer."

Song Wanyue raised her fist with a small fist, "Come on, brother."

Song Si was amused by him, and the pleasant laughter came to the next door.

Gu Yizheng was depressed and ate the very unpleasant pastry provided by the inn for free. He heard Song Si's laughter and immediately threw it back into the plate, stood up and walked out, and then suddenly turned around and sat down after walking for two steps, and took the pastry he threw again in a depressing manner.

Xiao Si covered his head, stood at the door, looking like an angry bag.

Xiao Si lowered his hand when he heard the laughter, moved forward two small steps, and said carefully, "It is rare to hear Master Song's happy laughter. There must be something happy. The master is worse than going over and be happy as well."

"I can't get over."

Gu Yi took a big bite of the pastry in a depressing manner and said vaguely, "The little girl must have told the elder brother about the silver notes. He is making fun of me, laughing at me for being unpromising, and not even hiding the silver in my private house."

Xiao Si,...

He moved a small step forward and carefully persuaded him, "I think it's not. It should be that Young Master Song was happy just now when he sold a bottle of peppermint oil."

Gu Yi looked at him with contempt and swallowed the pastry in his mouth with difficulty, "Is my brother such a superficial person? It's just a hundred cents."

"Young master, you can't think so. Although it's only sold for 100 cents, this is the first bottle of peppermint oil. It's so easy to sell, which indicates that the remaining peppermint oil will be sold very easily."

"Yeah?"

Xiao Si nodded desperately and instigated, "Young master, please go over and take a look. Maybe Miss Song is waiting to tell you this good news."

"Hmm?" Gu Yi stuffed the remaining pastry into his mouth, clapped his hands and stood up, raised his hand and knocked on Xiao Si's head, "It seems that I did not call you wrong just now, I've beaten you smart."

Xiao Si,...

He hurriedly took a step back, turned around and opened the door, and waited for Gu Yi to walk out, and he was completely relieved. He finally escaped again after this blow.

After Song Si finished laughing, he put the box containing the brush on the table and opened it. He saw that it was a wolf-haired pen inside, so he was so shocked that he didn't dare to move.

Seeing his abnormality, Song Wanyue also looked down and was stunned for a moment when she saw it was a wolf's brush. Then she pretended to be nothing and shook her hand in front of Song Si, "Brother, what's wrong?"

Song Si came back to his senses and covered the box with a snap, "This brush is too expensive, we can't accept it, I'll return it to Mr. Sun immediately."

After saying that, he hurried out with the box.

Gu Yi just opened the door and came in. The two of them almost collided. Gu Yi was so scared that he took a step back, his heels hit the threshold, and his body leaned back.

Song Si hurriedly reached out to pull it. The box in his hand fell to the ground without holding it firmly. The box was bounced off and the brush inside rolled out.

Song Si immediately felt scared and let out a cold sweat. He pulled Gu Yi to stand still and hurriedly squatted down to pick up the brush.

Gu Yixin patted his chest with lingering fear, and was about to ask Song Si what he was doing in panic when he saw the brush picked up by Song Si in his hand and said "Huh".

Song Si put the pen in, wiped the box surface clean with his sleeves, stood up and walked out.

Gu Yi asked puzzledly, "What are you doing with your brother?"

"Go and return the pen to Mr. Sun. It's too expensive and we can't accept it."

Gu Yi held him, "This pen is worthless, no need to pay it back."

"What do you know? This is a wolf pen, valuable."

Gu Yi looked calm, "I know, there are many in my family. I started practicing calligraphy since I was five years old and used wolf hair pen."

Song Si,...

"But, this is not a real wolf-haired pen, it is dyed with wool, and it is not worth much."

Song Si looked at him blankly, "Are you sure?"

"I'm very sure."

Gu Yi took the box in Song Si's hand and put it on the table to open it. He took out the brush and slid his fingers over the tip of the pen. "The wool pen is soft, has little elasticity, and the color is not natural. Brother can touch it."

Song Si started to touch it, and couldn't figure out any difference at all, and said, "But I see that he is exactly the same as the wolf-haired pen used by the dean."

"That's because you haven't used it, you'll know after using it."

Song Si was hesitant. He often asked the dean for advice on articles. Naturally, he had seen the wolf hair brush many times, and it looked exactly the same as the one given by Mr. Sun. But since Gu Yi has used the wolf hair brush since he was a child, he naturally would not have read it wrong. If it was really a wool hair brush, it would not be worth so much money.
