As soon as Ding returned to Chang'an, he closed the door and thanked the guests when he entered, mainly for the sake of Mr. Wang Chuanyi's brothers and the four girls in spring, summer, autumn and winter. Brother Wang Chuanyi said to Ding Yi: "Since we have set up the Ci'an Medical Center, we have also seen results, and the two of us have been aiming to govern the country and teach the people, but nothing has been achieved. Now that he is old, he is willing to guard the medical hall for his son, and continue to educate his son, so as to understand the avenue and hope that his son will be perfected. ”

Ding Yizhi did not want to get involved in the power anymore, so he gave full play to his skills in the medical hall and kept a little thought for himself.

When Siya saw the change in the appearance of the four women, she was surprised and couldn't help but want to try it herself, and she knew that there were still a lot of pills, but she could only use them after she reached adulthood, just like when she was hungry and only had one breath left, she saw many delicious foods in front of her and couldn't eat it in her mouth. Ding Yi has been living with Siya since he was a child, and when he saw Siya working so hard, his heart moved, and he began to think about how to refine a usable elixir for Siya and Wang Chuanyi's brothers. This pondering has been more than a month, and after many experiments, the Danfang has not yet been determined. The news outside the door that the emperor Li Shimin came to visit friends, Ding Yi thought about it for a while, and then knew Li Shimin's intention and invited Li Shimin to come to the lobby. At this time, only Ling Qifeng and Ding Yi were accompanied, and the four women stood behind the two after serving tea. Li Shimin looked at everyone, Ding Yi made people feel like a breeze and mist, and it could turn into everything at any time. Ling Qifeng is still transformed in the fog, and she can only feel it, but she can't understand it. The four women are like fairies, faintly intelligible in the light veil.

Li Shimin said bluntly: "This time I came to see Gongzi, firstly, to show my heart, I did my best to collect a batch of medicinal materials and things that are difficult to see in the world, of course, I will definitely look down on Gongzi in the eyes, but after all, it is my own little heart, please accept it." The second is that he is middle-aged and wants his son to set an heir for the Tang Dynasty. The third is whether Childe can promise me to become a long-term customer who can often come to the doctor for check-ups as a friend. ”

Ding Yi promised to accept the medicine, and he could come often. As for the heir himself, he will not interfere, and he also clearly told Li Shimin that he will be ready to return to the division at any time. As soon as Li Shimin heard this, he knew that Ding Yi was arranging to leave, and then he agreed, and Ding Yi took out a few pills and handed them to Li Shimin and said: "These are a few pills, which have healing, detoxification and life-saving, remember not to mention it to anyone, otherwise it will cause a lot of trouble, and even endanger your life, this is a sought-after thing in the cultivation world, pay attention to it, and do not leak it." ”

Li Shimin solemnly accepted it, knowing that this was Ding Yi renewing his life. A few years later, Li Shimin was seriously ill and could not be helped, took the pill left by Ding Yi, and came back to life, unable to explain the origin of the pill, so he had to fabricate his own experience in the underworld. That's an afterword.

After Li Shimin left, Ling Qifeng sighed: "My brother's friend has created the fate of others, and now I want my brother to open Chrysostom." ”

Ding Yi also smiled: "It's not a big deal, my sister is laughing." Go and take a look at the herbs that have been delivered. Saying that, he came to the front with Ling Qifeng.

Ding Yi looked at the things in front of him with different years and different medicinal effects, and suddenly felt something in his heart, and then sat on the stool next to him and thought about it carefully, and after a while, he got up and walked to the backyard, came to the backyard, and began to experiment with the new Danfang that he thought of.

After more than ten days of research, Ding Yi finally refined a new elixir. In the early morning, when the sun just appeared, Ding Yi came to the courtyard, and in the morning light, he remembered the scene when he practiced with Siya in the Ding family manor, and unconsciously practiced a set of swordsmanship, and after practicing, he looked up and saw Ling Qifeng standing at the door of the room, looking at himself intently. Ding Yi unconsciously shouted, "Senior sister, good morning." ”

As soon as Ling Qifeng heard Ding Yi's shout, the young figure appeared in front of him again, and he came over and raised his hand to wipe Ding Yi's habitual sweat, suddenly came back to his senses, and put down his raised hand with a smile. Ding Yi held Ling Qifeng's hand and said: "Sister, you rarely care about your children, but since I entered Ding's house, I haven't left you a step, without your care, how can I Ding Yi today, it is you who have given me a complete home and maternal love." Ah, this is the elixir I made again, which can completely make my brothers and sisters improve as soon as possible. As he spoke, he took out a bunch of bottles and cans like a treasure, and said this and that, happily comparing paintings.

Ling Qifeng looked at the slightly naïve Ding Yi he created, only showing a fifteen or sixteen-year-old baby face, and couldn't help but be ridiculous for his masterpiece, when it was completed, he asked Ding Yi if he was satisfied, but Ding Yi said that as long as Ling Qifeng looked satisfied with his own opinion, he was also a doll brought up by Ling Qifeng, and Ling Qifeng was in charge. Now it looks kind of ridiculous.

Ling Qifeng looked at the pile of jade bottles in his hand, and knew that this was prepared by Ding Yi for his children and the people in the Ding family's manor. Ding Yi has always regarded the Ding family manor as his home, and everyone in the manor as relatives. All the people in the manor also pampered Ding Yi as their little son. Therefore, when Ding Fugui heard the minister say that Ding Yi was like this and that in the court, he would look at each other angrily regardless of the place, and directly said that he wanted the other party's life, which shows how much Ding Yi was favored in the manor. Ling Qifeng was looking at the jade bottle and thinking about it, so he listened to the person next to Ding Yi: "Go and invite the four young ladies to come." After speaking, he said to Ling Qifeng: "The pill in my sister's hand will be brought back to the manor for use, and I am ready here." ”

The four were practicing in retreat, and when they heard that Ding Yi had invited them over, they were all excited. Zhilu Dao Ding Yi was trying to find a way to make alchemy for them, and now he invited them over, indicating that the pill he had refined had basically come out, and they all ran to the courtyard excitedly.

When I came to the courtyard, I saw Ling Qifeng holding a bunch of jade bottles in his hand, and the pills refined by Zhi Lu Dao were completed, and they all surrounded Ling Qifeng, waiting for the pills to be issued. Ling Qifeng looked at the four girls lovingly and said, "There is no pill for you here, all of you are with the son." ”

Siya turned his head to Ding: "Why don't you take out ours." ”

Ding Yi smiled and said to Siya: "I didn't just refine the pill and let people invite you, I didn't care about handing it over to my sister, but this time I want to protect the Dharma for you." ”

Ding Yi waved his hand to Ling Qifeng as he spoke, and led Siya to the practice ground. When I came to the practice place, I opened the small door leading to the underground, came to a small hut made of stone blocks underground, and said to Siya: "I know that you want to break through as soon as possible, so this time you not only want to change your appearance, but also improve your skills. ”

It was the first time Siya saw Ding Yi talking to them so seriously, and she knew that this time was very dangerous, and it must be very dangerous. The four of them glanced at each other, nodded to each other, the four of them have lived together for a long time, and they can understand each other with one look, and they naturally know each other's intentions at this time. Chunya said to Ding: "Son, let's arrange it, we are not afraid of danger, and we can overcome the pain." ”

Ding Yi looked at Siya's firm face again and said, "Your four aunts have all become seventeen or eighteen, have you thought about it, it's too difficult for me to do it." ”

Siya said: "We are the same age as the son, so we will be girls for the son and the wife, as long as the son and the wife do not dislike us for a day, we are the girls." ”

Ding Yi looked at Siya again, Siya nodded firmly at Ding, Ding Yiyi: "This retreat is extremely risky, you must keep your mind, no matter how much pain there is, you must not lose your mind, once you lose your mind, it will cause lifelong dementia and paralysis." I'm on the side, and you must hold on. ”

After speaking, let the four girls sit down on all four sides. Then put out a formation, in the middle of the formation, Ding Yi put a piece of garden-like chalcedony, as soon as the chalcedony was put into the array, the formation immediately began to operate, Siya suddenly felt a pure aura to press himself, and couldn't help but run the exercises, with the operation of the exercises, the aura of the chalcedony entered the body, and suddenly felt that the body had been purified by the aura. This is when Ding Yi was in danger at the beach, he felt that chalcedony can not only enhance his strength, but also purify his body and strength, and help practitioners quickly precipitate his strength. If it wasn't for the four women who urged the chalcedony to absorb it with all their might last time, with the help of the chalcedony purification and precipitation, it might be over. This time, in order not to leave sequelae for Siya's future cultivation, Ding Yi actually spent such a large amount of money to use chalcedony to first purify Siya's current power and body, and when this step is completed, give each person a newly refined pill, and when the medicinal power is dissolved, Ding Yi each person with needles, and then the pill, and so on.
