The night was getting deeper, and Li Dang was already sleepy and turned over on his back, but the beauty was in front of him, and he didn't dare to stretch his waist and yawn out of courtesy, but gradually, Li Dang found that the oxygen in his head was getting less and less, and his thinking was much duller.

But Xu Xian'er was still interested, asking about the medical questions she cared about one after another.

"Doctor Xian'er, you see that the moon is clear outside, why don't we go to the pond for a walk." Li Dang felt that it was still necessary to go to the courtyard to relax, otherwise, his upper and lower eyelids would have to fight sooner or later.

Li dared to say that he had no intention, but Xu Xian'er had the intention to hear it.

Xu Xian'er lowered her head shyly, how could a yellow flower girl casually accompany a strange man, a lonely man and a widow wandering in the moonlight. Fortunately, Xu Xian'er has practiced medicine since she was a child and has seen a lot of the world, she is not as shy as the young lady of an ordinary big family, she hesitated for a while, but still agreed to Li Kang's invitation.

At this moment, except for a few people who were on duty at night and those who were ordered to serve Li Kang and Xu Xian'er, everyone else in the courtyard of the Peng family had already fallen asleep.

Outside, frogs, drums and insects chirp, intertwined.

The two of them walked through the front yard one after the other, and then passed through a long corridor to the pond in the backyard of the Peng family.

The pond is not very large, but the vicinity is full of rare grasses, and there is a dark fragrance. In the pond, the lotus leaves are in the fields, the breeze is coming, and a full moon rises and falls on the water surface.

Li Dang walked in front, he closed his eyes and took a deep breath, he was suddenly refreshed, and when he looked back, Xu Xian'er behind him was light and agile, and her skirt was flying, like a white epiphany that gradually bloomed, exuding a tempting and refreshing atmosphere in the misty moonlight.

is really a woman who doesn't eat fireworks in the world, Li Dare didn't feel stunned.

"Li Gongzi's medical skills are so superb, I don't know who the teacher is, can you tell the little girl?"

"Xiao Ke does have a lot of mentors, but they are not famous, and if you say it, the fairy doctor will not know." Li Dang looked at Xu Xian'er's bright smile and shook his head.

Xu Xian'er didn't believe that any ordinary quack doctor could bring out a young and skilled Lang Zhong like Li Kang, and when he saw that Li Kang was unwilling to tell his master's name, he thought that Li Kang had some taboos, so he stopped asking.

"Xiao Ke really envy the origin of Xian'er's divine doctor's family!"

Li Dare is most interested in acupuncture and moxibustion for internal and external treatment, but since the Republic of China, traditional Chinese medicine has declined, and acupuncture skills have been lost.

After Li Dare finished speaking, he saw that Xu Xian'er was about to cross a small ditch, he subconsciously stepped forward and politely stretched out his right arm to Xu Xian'er.

Xu Xian'er hesitated for a moment, but still put her soft and boneless jade hand in Li Kang's palm.

Li Dang gently held Xu Xian'er's slender fingers, and with a slight force on his arm, he took Xu Xian'er across the ditch, and looked at it, Xu Xian'er's pink face was scarlet, and this clear and bright epiphany had already turned into a gorgeous peach blossom.

"Xu Fengyu (Xu Xi) cured Emperor Renzong's illness back then, and became famous all over the world, and later entered the Hanlin Medical Class, which can be described as peach and plum all over the world, how many years have passed, why does Xian'er Niangzi now have to support such a big Xu family security hall by herself?"

Seeing that there was no one nearby, Li Kang also asked the doubts in his heart.

"Since the great-grandfather became an official, most of the descendants of the Xu family have abandoned medicine and entered politics, only Xian'er's grandfather inherited the Xu family medical hall, but unfortunately the grandfather's vein is not prosperous, only the only son of the first father, the first father was conscripted with the army to crusade against the Western Xia ten years ago, after his accident, the first grandfather had to pass on the medical skills to the woman's Xian'er, the year before last, after the grandfather passed away, Xian'er did not want the Xu family medical hall to disappear like this, so he took over the medical hall, Xian'er also hoped to find a person as soon as possible, to help Xian'er carry down the Xu family medical hall together......" Xu Xian'er buried her head and told the story. As she spoke, her eyes turned red, and her voice grew softer and softer, until at last she couldn't hear herself.

"I'm sorry, Xian'er lady, I reminded you of something unhappy, I'm sorry." Li Dang didn't hear Xu Xian'er's last words clearly, he saw that he had induced Xu Xian'er to think of the sad past, and he felt a little remorseful.

Xu Xian'er couldn't help but apologize when she saw Li Da, lowered her head, stared at the hem of her white skirt, revealing a pair of crested embroidered shoes that she saw Xiaojiao, and didn't dare to raise her head again.

Early the next morning, Li Dang bid farewell to Peng Yuliang early in the morning.

He proposed to Peng Yuliang to plant willow trees in the courtyard of Peng's house, and moved Mrs. Peng's boudoir to the willow forest.

This is what he thought of when he and Xu Xian'er visited the pond at night yesterday and saw a line of willow trees by the pond, and he remembered reading a blog post on the Internet before, which talked about the killing effect of the fragrance of willow trees on tuberculosis bacteria.

Li Dang knew that in order to give full play to his expertise in integrated Chinese and Western medicine, he had to find ways to prepare some commonly used Western medicines, such as aspirin, penicillin, glucose, and so on. The aspirin, which has fast efficacy and few side effects, is made of salicylic acid extracted from willow branches and then chemically synthesized, and more importantly, salicylic acid is an important Western medicine for the treatment of tuberculosis by inhalation.

Peng Yuliang heard someone mention that Li Kang and Xu Xian'er talked about going to the pond together in the middle of the night, he thought that Li Kang was just picking up girls, but he didn't expect Li Dang to go to the pond for his wife's illness, and his good impression of Li Kang in his heart increased a few points.

Peng Yuliang was not disgusted by Li Dang's approach to Xu Xian'er, on the contrary, in his opinion, Xu Xian'er and Li Dang were a pair of beauties made in heaven.

"Brother Li Xian, according to Brother Yu, although the fairy doctor has declined in the family over the years, but after all, she is a beautiful lady, and she has a dignified demeanor and extraordinary demeanor, and she is even more compatible with you in terms of medical skills. Peng Yuliang held Li Kang's hands and said in a long voice.

It's not a pot that can't be opened, there is still a gentle one at home waiting for him to go back, Li Dare shook his head again and again.

"Brother Xian, but he can't live up to the fairy doctor?" Peng Yuliang said.

Li Dang's eyes widened and he stared at Peng Yuliang in astonishment, he didn't know the meaning of Peng Yuliang's words.

"Peng heard that the virtuous brother once invited the fairy lady to accompany him late at night, and also held the jade hand of the fairy lady, the virtuous brother is a scholar, of course he understands the truth that 'men and women do not kiss', so Peng reminded the virtuous brother to have a psychological preparation as soon as possible, and he can't live up to the friendship of others." Peng Yuhao seemed to see through the doubts in Li Kang's heart, and he said with a smile.

Li Dang recalled that after being shaken by himself last night, Xu Xian'er was uneasy in front of him, and was shocked, this white and flawless, dustless goddess doctor would not be responsible for himself because he shook his hand gently, right?

He recalled the action of stretching out his hand, and secretly screamed in his heart, in Xu Xian'er's opinion, it wouldn't be that I thought I was expressing my love to her, right?

If it was in a previous life, shaking a girl's hand would be a common thing, but after all, this was in the Song Dynasty, and Li Dang didn't know what kind of trouble this handshake would cause to himself.
