The Liu family's house is huge, with a total of six courtyards, and Mrs. Liu has been living in the quiet courtyard of the courtyard in her later years.

Du Feiyun followed Liu Xiangtian to the outside of Mrs. Liu's bedroom, and saw two maids bending over with a wooden basin from a distance, filled with water and soaked in sweat towels. It's just that the water and sweat towel are dark red, obviously stained with blood.

After the housekeeper Liu Zhong opened the door for the two, he consciously stood outside the door, and Du Feiyun walked into the bedroom accompanied by Liu Xiangtian.

As soon as I entered the room, I was greeted by a sour and rotten stench, which made my chest feel stuffy and I couldn't breathe.

On the wide wooden bed, covered with a satin brocade quilt and a silk gauze tent rolled up, the old lady was lying quietly on the bed. Originally, there were two maids waiting in the room, and every other hour they would wipe the body of the old lady with a sweat towel dipped in water, but they had just finished wiping and left with a wooden basin.

Du Feiyun endured the unpleasant stench, came to the bedside and gently lifted the brocade quilt to check on Mrs. Liu's illness. Liu Xiangtian stood aside, his eyes fell on his mother's face, and the expression in his eyes was gloomy.

Mrs. Liu was in a coma, her eyes closed and she was lying on the bed unconscious. She had been a very white and rich woman, but her face was now covered with dark red bumps the size of eggs, and there were pus and bruises in them, which was very hideous and terrifying.

Du Feiyun checked it, not only his face, but also his arms, thighs, hands and feet were the same. Seeing this, Du Feiyun didn't need to look any further, he could imagine that the old lady must be covered in this kind of pus and blood blisters.

Seeing the miserable appearance of the old lady, Rao is Du Feiyun has never had a good impression of the Liu family, and he can't help but feel compassion for the old lady, and his heart is a little heavy.

After checking it, Du Feiyun covered the silk quilt for the old lady. Liu Xiangtian immediately turned his head and did not open his mouth to ask, but looked at Du Feiyun with an inquiring gaze, the meaning of which was self-evident, naturally he was asking Du Feiyun what he could do.

Du Feiyun did not answer, and motioned for Liu Xiangtian to take a step to speak. The two left the bedroom and came to the side room, Liu Xiangtian couldn't wait to ask, "How is it, do you have a way?"

Du Feiyun still didn't answer, but opened his mouth to ask an irrelevant question.

"What kind of food did the old lady eat on the night she became ill?"

As soon as these words came out, the temperature in the room dropped instantly, and a cold air flow spread from Liu Xiangtian's body, and his expression was rapidly becoming cold.

"Bastard boy, do you want to give me an answer with the rumors in the market?" Liu Xiangtian's voice was cold and low, but the murderous aura in it was self-evident. Du Feiyun, who was locked by his powerful momentum, although his expression did not change at all, there was a shock between his internal organs, and his heart was even more swaying.

"You misunderstood, what I want to ask is, has the old lady eaten ginger recently?"

Du Feiyun had no doubt that if he didn't say the problem directly, he was afraid that Liu Xiangtian would be angry and hurt people. Liu Xiangtian was a dignified Qi Refining Stage cultivator, dozens of times more powerful than Du Feiyun, and the coercion he emitted alone was enough to suffocate Du Feiyun. In order to avoid accidents, he decided to be frank and outspoken.

"Mao Jiang?" Hearing Du Feiyun's question, Liu Xiangtian's momentum gradually dissipated again, and then returned to normal, after a little thought, he nodded and replied: "Not only that night, but in the past month, the old lady has been taking Mao Jiang decoction juice. ”

Ginger is a type of herb that can be used to treat tooth loss, bleeding and other ailments. Mrs. Liu's teeth have not been good in the past two years, and her teeth have fallen out a lot, so some time ago, Liu Xiangtian specially ordered the housekeeper Liu Zhong to go to Qianjiang City to buy back these medicinal materials for Mrs. Liu to take.

"Well, here's the problem. Hearing Liu Xiangtian's confirmation, Du Feiyun finally confirmed the cause of Mrs. Liu's illness. Before, he had always speculated about the cause of Lao Taijun's illness, and he thought that his guess was eight or nine, but now that he heard the news with his own ears, he was even more sure in his heart.

"What's the matter? Could it be that Mao Jiang has a ......?" Liu Xiangtian's brows instantly erected, and there was a trace of bad thoughts in his heart. However, Du Feiyun's words made him understand.

"It's not that there is a problem with Mao Jiang, the problem is that the old lady took Mao Jiang decoction that night, and then ate the tripe soup made by the eldest lady. Mixed with beef, it will produce a violent fire poison, quickly burn out the heart and lungs, and can kill people in a short time, so ......",

Du Feiyun didn't say the latter words, but this was enough. At least, Liu Xiangtian has understood.

"Bastard!" Liu Xiangtian's face instantly turned black, his lips trembled because of his anger, and he smashed his fist on the table in anger, instantly smashing the pear wood round table to pieces.

Du Feiyun naturally didn't bother to pay attention to Liu Xiangtian's anger, although he understood Liu Xiangtian's mood at this time, and also knew that Liu Xiangtian must have thought that the eldest lady Qin Yan had poisoned the old lady. It's just that he didn't intend to explain anything, his purpose and task was just to heal the old lady, and he wouldn't intervene in the Liu family's family affairs.

In fact, he knew the cause of this disease entirely because he had read anecdotes in the Lieshan Travel Notes. He believed that the people of this world realm probably didn't know the cause of the Dao, otherwise the Divine Doctor Xue of Qianjiang City would not be helpless. Therefore, Qin Yan, the eldest lady of the Liu family, definitely did not have the intention of poisoning the old lady, at most it can only be regarded as a coincidence.

After a long time, Liu Xiangtian calmed down the anger in his heart and restrained his emotions, then he turned around and looked at Du Feiyun with a solemn face and said, "Can it be cured?"

"Of course, but I need you to prepare some medicinal herbs, a stove and a crockpot. Also, I need a quiet room where no one disturbs me. ”

Du Feiyun shrugged his shoulders and reiterated again: "Remember, no one is allowed to disturb you, including you!"

Seeing Du Feiyun's tone, Liu Xiangtian originally wanted to be angry, but thinking that maybe his mother's safety would fall into Du Feiyun's hands, he had to suppress his anger.

Du Feiyun wrote down a prescription with a brush, Liu Xiangtian picked up the prescription and looked at it for a while, the more he looked at it, the more his brows wrinkled, and his expression was a little embarrassed.

On the prescription written by Du Feiyun, there are more than 20 kinds of medicinal materials, all of which are rare and valuable. The medicinal materials of the entire prescription were worth more than a thousand taels of silver, which was also the reason why Liu Xiangtian's expression was embarrassed. Although a thousand taels of silver made Liu Xiangtian's flesh hurt, his mother's safety was more important, so he had to order the housekeeper Liu Zhong to buy all these herbs.

An hour later, Liu Xiangtian carried a large bag of medicinal materials in one hand, a medicine stove and a clay pot in the other, and took Du Feiyun to a rockery in the back garden. After putting down the medicine furnace crockpot, Liu Xiangtian exerted his strength to move away from a thousand-pound boulder outside the rockery, and a black Yongdao mouth was exposed. Walking down this Yongdao crossing, it is where the secret room of the Liu family is located.

Entering the secret room, Liu Xiangtian put down everything and left. Du Feiyun closed the door made of stainless steel, then placed many medicinal materials on the stone table, crossed his knees on the ground and began to cultivate.

The reason why Liu Xiangtian was asked to buy a lot of medicinal materials was because Du Feiyun was going to refine the elixir again, and he wanted to refine an elixir called Bifu Elixir! This kind of elixir was found by him in the Lieshan Pharmacopoeia, and the medicinal effect happened to treat Liu Laotaijun's disease.

There are many anecdotes recorded in the travel notes of Lieshan, among which there is an anecdote in which the situation is like that of Mrs. Liu, who also accidentally ate ginger and beef, and then became ill, which was miserable. In the Travelogue of the Burning Mountain, the elixir needed to cure this strange disease is annotated, as well as the medicinal materials and techniques required to refine the elixir.

The powerful effect of Bifu Elixir does not lie in enhancing the meridian physique, nor in increasing the cultivation of Yuan Force, nor in allowing the monk to improve his strength. Its only function is to remove the poison of fire from the monk's body. Moreover, this medicine is mild, not only monks can take it, but also ordinary people can take it without worrying about harm.

Therefore, refining this medicine to cure the old lady's illness is the right medicine.

Du Feiyun understood that only monks who had reached the Innate Stage realm could refine pills, so the news that he could refine pills should never be known to outsiders. There are too many secrets hidden in him, including the Nine Dragons Medicine Ding and the Lieshan Pharmacopoeia, as well as the fact that his strength in the refining period can refine pills. If it is known, it will be a disaster.

Because of this, he chose to go to the list in the middle of the night, in order not to attract attention. asked Liu Xiangtian to prepare a stove and a clay pot and a secret room for him, and claimed that no one could disturb him, also to make Liu Xiangtian mistakenly think that he was preparing decoction. All this is to hide his secrets and protect his own safety.

Now, everything is ready, only the east wind is owed. As long as he enters the cultivation for a while, and after his mind is calm, he can refine the Bifu elixir with all his might, and then he can cure Old Taijun Liu. At that time, he will be able to win the bet with Liu Xiangtian, not only getting a heavy reward of 1,000 taels of silver, but also three hundred-year-old ginseng and Ganoderma lucidum.
