Lin su'er is telling the truth.

When she saw Gu Cheng just now, she felt that he spoke loudly, but some of them were short of Qi. At this time, when she pinched the pulse, it was indeed a smooth pulse and a standard kidney deficiency pulse.

But Gu Cheng was completely stupid when he heard Lin su'er's words.

"You, you talk nonsense!" Several seconds later, he came back to his senses and was almost angry. "Who has kidney deficiency? I'm in good health!"

He was so angry that he wanted to break away from Lin su'er's hand, but Lin su'er didn't know how to hold his wrist. It was such a thin hand. When he held his wrist, it seemed to grasp some key part and let him break away a little, it hurt and burst into cold sweat.

"I'm not talking nonsense." In the face of Gu Cheng's retort, Lin su'er retorted seriously, "do you often wake up and go to the bathroom in the middle of the night, and often feel frequent urination and urgent urination? From time to time, you still feel dizzy, tinnitus and cold limbs?"

Every time Lin su'er said a word, Gu Cheng's face turned white.

I've really seen a ghost. Lin su'er is right in everything!

"How do you know..." he blurted out in shock, but when he said it, he found that he had said the wrong thing and closed his mouth.

But it's still too late. The classmates around have heard Gu Cheng's words.

Everyone's faces suddenly became colorful.

"I'll go. Lin su'er is really right, so Gu Cheng really has kidney deficiency? How old is he? This is too exaggerated."

"I think it's normal. It's strange that he changes his girlfriend so often."

"But how does Lin su'er know... Speaking of it, how do I feel that Lin su'er seems a little different on the peace day?"

The students all lowered their voices and whispered, but the classroom was so big that the voices of those discussions were clearly transmitted to Gu Cheng's ears.

His face turned green with anger.

"Lin su'er!" He looked at the culprit in front of him and immediately ignored the pain of his wrist. He shook her off heavily and shouted, "are you looking for death!"

"I didn't." In the face of Gu Cheng's roar, Lin su'er's face remained unchanged. He just took out a card from his pen box and handed it to him with a sincere face. "The doctor is kind-hearted. Although you are impolite, for the sake of your classmates, if you ask me to help you treat kidney deficiency, I can give you a 20% discount."

Gu Cheng looked down and saw that Lin su'er had a handwritten card written on it——

[Lin su'er, the thirty second generation of ghost doctor, can cure all kinds of diseases. Contact information: 13xxxx0]

This, this special is a business card?

Looking at this extremely rough handmade business card and the same slogan as the swindler's small advertisement on it, Gu Chengqi almost rolled his eyelids and fainted.

Was he fooled by someone!

"Lin su'er, you, you wait for me!" Gu Cheng was trembling with anger and roared at Lin su'er before he rushed out of the classroom.

"Ah, you don't treat?" Seeing Gu Cheng leave like this, Lin su'er looked disappointed.

She looked down at the card in her hand and shook her head regretfully.

Since she made up her mind to carry forward the ancient medicine yesterday, Lin su'er immediately made only a few small business cards by hand.

Because she knows from her original memory that doing business in this world needs publicity. Since she wants to make her name as a ghost doctor, she naturally needs a business card.

"It seems that this business card is not professional enough, so it can't attract customers' interest." Lin su'er said a word to herself. As she put away her business card, she made up her mind to make a high-grade business card quickly to attract more customers.
