The beautiful woman drove the bamboo flute to take Wu Feng to the school square. At the moment, most of the disciples in the school are on the way back and forth from the trial battlefield. The square is empty and silent.


    "I''ll inform the Presbyterian, and I''ll inform you to move there as soon as I make your robes." the beautiful woman whispered.


    Wu Feng''s face showed gratitude.


    The beautiful woman smiled, then cared for a few words, and then floated away.


    After she left, Wu Feng immediately went to the gate of the mountain. This time, in the trial battlefield, he not only got the heavenly pulse chanting Sutra from the charming woman, but also got the golden fragrant flower and fruit, which is the main material for refining keel pill.


    The top priority is to purchase other auxiliary materials and refine them. In this way, the peak of promotion the day after tomorrow is just around the corner.


    ……


    Fang City, medicine shop.


    As soon as Wu Feng came in, he heard a surprised voice: "you''re finally here!" the speaker was a woman, dressed in white as snow, with a beautiful appearance. Naturally, she was su Rongrong.


    "Well." Wu Feng touched his nose, but he didn''t expect her to be so enthusiastic.


    "I haven''t seen you for three months. I thought you would never come again." Su Rongrong said with a trace of sadness.


    Wu Feng said reluctantly, "I can''t come because of some delay. I''m here to buy some herbs. I don''t know if you have them here."


    "What medicine?" Su Rongrong''s eyes lit up. Last time Wu Feng purchased a large number of fire elixirs, she made a lot of money.


    "Cold Python pulp, golden jasmine, youshao grass..." Wu Feng reported the names of six or seven herbs in succession, and then looked at the woman.


    Su Rongrong was puzzled at first when she heard these herbs. Later, after hearing them, she immediately showed a trace of shock and said in silence, "isn''t this the auxiliary medicine of Longdan?"


    Wu Feng nodded and said, "good."


    Su Rongrong looked at him in amazement and said, "you, can you really refine the third-order pill? How can it be? Even the Murong master of your alchemy academy may not be able to refine it easily?"


    Wu Feng said quietly, "can you buy these herbs?"


    Seeing that Wu Feng didn''t answer, but asked about the medicinal materials, Su Rongrong immediately responded. It was a great taboo to ask other people''s privacy. She showed some apology on her face and quickly replied: "These materials are the auxiliary materials of the third-order pill. Even my Tianzhou medicine shop can''t take out so much at one time. If you give me a few days, I can barely get together, but I can''t get the cold Python marrow."


    Wu Feng frowned and showed some disappointment in his eyes.


    He also knows that the dragon bone pill is a third-order material. Even if someone can refine it, the medicinal material is too rare to find in the world. For example, the golden fragrant flowers and fruits in his hand may be only a few in total on this land, and one will be less when used up.


    "However." Su Rongrong hesitated and said, "there''s a big auction recently. Maybe there''s this thing in it. You can go and have a look."


    Wu Feng was surprised and said, "is the auction held in this way?"


    Su Rongrong nodded. She whispered, "most people can''t get into the auction. It happens that there are three places in my Tianzhou medicine shop. I can give you one. I don''t know whether there is the cold Python marrow in the auction."


    Wu Feng pondered for a moment and said, "thank you. I''ll take a chance. I hope I can meet you."


    Su Rongrong smiled and said, "I''ll take you to the auction. It should be about to start now. It''s a good time for you to come." she turned back to the shopkeeper and left the medicine shop with Wu Feng.


    Su Rongrong took him to the center of Fangshi, where there was a huge building. The dark tall buildings were like mountains, and the pavilions were built straight into the clouds.


    "Come with me." Su Rongrong didn''t choose the main door, but took Wu Feng around to the back of the building. There was a side door. There were two people stationed at her door. Looking at the temples on her forehead, they were the strong ones the day after tomorrow.


    Su Rongrong took out a wooden plate with a medicine word engraved on it. When they saw the wooden plate, they recognized it for a while and nodded to make way.


    Su Rongrong went in with Wu Feng. There was a dark passage inside. Soon after walking along the passage, the line of sight in front suddenly opened and exposed an open space.


    "This is an underground auction house. There are some forbidden goods in the things auctioned here. You should be mentally prepared." Su Rongrong whispered.


    Wu Feng''s eyes flashed and nodded gently.


    At this time, Su Rongrong took him to the open space. There was an old woman over 80 years old, clutching a crutch. Her wrinkled face was dead, but her eyes were dark and sharp, so people didn''t dare to look directly.


    "Granny Gao, give me two sets of clothes." Su Rongrong and the old woman seemed familiar and smiled.


    When the old woman saw her, a smile appeared on her dry face, like cracked bark. Her voice was hoarse and said, "Xiao Rongrong, why are you interested in coming?"


    Su Rongrong said, "I brought this childe."


    "Oh." the old woman looked up at Wu Feng, took back her eyes without interest, took out two sets of dark cloaks from a wooden cabinet, handed them to Su Rongrong, and said, "there are a lot of things at this auction, which attracts many people. You should be careful not to expose any property, otherwise it will be very troublesome to be nailed."


    Su Rongrong said with a smile, "I''m not afraid of anyone with my mother-in-law."


    The old woman gave her a spoiled look and said, "well, if you feel that someone wants to track you, come to me."


    Su Rongrong nodded.


    After taking over the dark cloak, Su Rongrong put on one and gave the other to Wu Feng. When they dressed up, they couldn''t recognize their original appearance at once.


    "Let''s go." Su Rongrong whispered, "when you auction later, you have to change your voice, otherwise you will still be recognized."


    Wu Feng was surprised. He didn''t expect this girl to be so careful. He nodded, which he himself considered.


    Immediately, the two walked along a passage ladder next to the open space towards the underground auction.


    Before long, he came to a wide hall, where a large number of figures gathered, all wearing dark cloaks, wandering in the hall like ghosts.


    Above the hall is a high auction table.


    Su Rongrong was familiar with the road, took Wu Feng to find a seat, pressed her voice hoarse, and said, "the auction should start soon. Let''s wait."


    Wu Feng nodded slightly.


    While they were waiting, more and more people poured in, all wearing dark cloaks, as gloomy as ghosts.


    With the passage of time, the auction finally began. A chubby middle-aged man walked up to the auction platform and said to the crowd: "everyone, the auction has begun. Everyone is quiet. I won''t say more nonsense. Let''s start the auction of the first article!"


    Everyone in the hall was quiet.


    I saw two young girls holding a tray, came to the auction table, lifted the red cloth on the tray and revealed something inside.


    "Ah!" Su Rongrong''s face changed greatly.
