"That's right, Uncle Master! In my early years, I knew of this underground auction. Many times, I bought rare herbs in this auction!" Qin Changfeng said hurriedly.

"Okay, in that case, we should go and take a look." Xiao Yi nodded his head.

When Qin Changfeng heard that Xiao Yi had agreed, he couldn't help but be overjoyed. He hesitated for a moment before saying, "Uncle Master, then I'll have to trouble you to help me check if the Soul Weapon is real or fake. If it's real, then I'm determined to get it!"

"Haha." Xiao Yi looked Qin Changfeng up and down and said with a smile, "That's true. You have stepped into the Qi-refining Stage. It's time for you to have a Soul Weapon. Moreover, it's time to raise your flying sword carefully!"

Hearing the words "flying sword", Qin Changfeng's face changed dramatically. A look of extreme longing came to his face. Flying swords were the dream of so many cultivators. Flying through the sky and earth, taking the enemy's head from thousands of miles away was like taking away something from their bag. This was the flying sword in Qin Changfeng's mind! However, it was not an ordinary thing. Qin Changfeng had only seen it when he was in the Dark Medical Sect. He had never seen it since he entered the secular world.

Now, Xiao Yi actually mentioned flying swords, which made Qin Changfeng's heart jump wildly.

Xiao Yi looked at him but did not say anything. He thought for a while and said to Qin Changfeng, "In this case, I'll go to your house to refine some suitable pills. It's better to use them in preparation for the auction at night."

When Qin Changfeng heard that Xiao Yi wanted to refine pills, he was so happy that he couldn't agree more. The two men hurriedly led the way.

Xiao Yi sent a servant to bring a message to Shu Wan, and then he went back to the Baicao Hall with them.

As soon as Xiao Yi entered the door, he recited a prescription. "Ginseng, dragonfly, dried-up grass!" He ordered Qin Guo to follow the prescription and deliver goods to the secret room.

Qin Changfeng had been away from the Dark Medical Sect for more than a hundred years. Today, he was finally able to see his elder refining pills. He was so happy that he trembled all over. He volunteered to be Xiao Yi's servant boy.

Xiao Yi smiled faintly. Knowing that he wanted to observe his pill refinement, he naturally agreed.

After sending the medicinal herbs to Xiao Yi, they closed the secret room door and told Qin Guo to be outside the door, and no one was allowed to disturb them.

As soon as Xiao Yi left his hand, he released the Fire Dragon Cauldron, an ancient treasure.

That desolate and simple aura immediately blew over, causing Qin Changfeng's heart to rise with respect.

Then, Xiao Yi summoned Gulu, the monster snake, and it spat a mouthful of Earth-Yin fire at the bottom of the Fire Dragon Cauldron.

"Although I don't know its name, I can tell from its extraordinary aura that it is definitely not an ordinary item. Uncle Master, you are at such a young age, You possess such a huge cauldron and a Spiritual Beast that can spew Earth's Yin Fire. This kind of fortune is truly worthy of admiration." Qin Changfeng's eyes lit up as he sighed.

"Changfeng, I'm going to make some Tendon-Changing and Bones-Improving Pills for ordinary martial artists to take. Although it is not too expensive, it's suitable for tonight's auction so that it won't cause too much trouble." Xiao Yi sat cross-legged on the ground with a smile and threw medicinal materials into Qin Changfeng while talking.

This Tendon-Changing and Bones-Improving Pills required a hundred-year-old spirit medicine. Qin Changfeng had already prepared it. It was hundred-year-old ginseng, full of Spiritual Energy. Once it was injected into the Fire Dragon Cauldron, it gave off a strong fragrance of medicine.

Xiao Yi also started to refine elixirs without any distractions.

Xiao Yi opened the Fire Dragon Cauldron the moment the medicinal fragrance came into contact with his nose. He had actually obtained a total of sixty-eight fire-red Tendon-Changing Bone Pills.

After throwing out two pills as rewards to Gu Lu, Xiao Yi took out 12 and handed them to Qin Changfeng. He smiled and said, "These are for you. Your grandson, Qin Nianen, is just in time to use them now!"

Qin Changfeng gratefully took the jar of Tendon-Changing and Bones-Improving Pills. After looking at it carefully, he was shocked and said in a shocked voice, "Heavens, Martial Uncle, you've made a level six pill!"

Xiao Yi smiled but didn't say anything. With the current strength of his Divine Awareness and the Fire Dragon Cauldron and Fire of Earth and Yin, it was very reasonable for Xiao Yi to refine a level six medicinal pill.

However, in the current secular world, those who really knew how to refine pills were extremely rare, let alone those who could refine level six pills. This made Qin Changfeng's admiration and admiration for Xiao Yi reach an incomparable level in an instant.

"I still have a Fate Pill for Qin Guo. It can help him enter the Qi-refining Realm as soon as possible. But remember, before he takes it, he must remember to recite the Concentration Poem. Otherwise, it's very dangerous." Xiao Yi casually threw Qin Changfeng another Fate Pill.

Qin Changfeng trembled all over. This Fate Pill was a level four pill; it was known as one of the top ten rare medicines in the Cultivation World. Xiao Yi gave them two pills at once. Qin Changfeng was deeply moved by Xiao Yi's great kindness.

Seeing that Qin Changfeng was about to kneel down and thank him again, Xiao Yi hurriedly held him up with one hand and stopped him. He smiled and said, "Changfeng, there's no need to be so polite. You and I are from the same sect. We should go in at the same time. In the future, whatever I will obtain, I will share one with you. If we're lucky tonight, I hope that I can meet the main ingredient to refind for the Golden Pellet of Spirit Realm. In that case, our progress will be much faster."

"The Golden Pellet of Spirit? Could it be that it's a level four pill that can expand one's Aantian and cause one's True Energy to surge?" As the boy of the past under Xiao Yi, Qin Changfeng was naturally experienced and knowledgeable.

"That's right. The benefits of the Golden Pellet of Spirit of Essence are beyond words. Although it's hard to find the needed main ingredients, it's not completely impossible. It's just that 'Origin Dew' is extremely rare." Xiao Yi frowned and said carefreely.

"In all these years, I have never heard of the Origin Dew. However, it depends on luck. Perhaps, Uncle Master will be able to obtain it tonight," said Qin Changfeng.

The two of them made some more preparations. After Xiao Yi had dinner together with them in Qin's Mansion, Qin Guo arranged an Audi to send Qin Changfeng and Xiao Yi directly to the North Alley.

The alley was located in the northern suburbs of the capital. It was a very remote place. When they arrived at the entrance of the alley, Xiao Yi and Qin Changfeng got off the car and walked all the way there.

Qin Changfeng, as he said, was already familiar with this place.

Along the way, from time to time, there were all kinds of identity verification by the organizers, but when they saw that it was Qin Changfeng, they all respectfully let him in.

Qin Changfeng, known as the treasure of Jing City and the miracle doctor of the present age, was known by everyone. Moreover, besides being a doctor, as the head of the Baicao Hall, his family background was even more remarkable. This underground auction was targeted at customers such as Qin Changfeng. How could the organizers not be respectful to him?

However, Qin Changfeng had not moved for a long time. This time, he was full of energy and seemed to be stronger and more robust than years ago. What surprised everyone was that Qin Changfeng, such an old fairy, paid tribute to this ordinary-dressed young man.

"Who on earth is this young man?" People who saw Qin Changfeng tonight couldn't help guessing in their hearts.

Qin Changfeng followed Xiao Yi's instructions and did not introduce Xiao Yi to anyone. Moreover, he also followed Xiao Yi's instructions and tried his best to restrain himself from being overly respectful to Xiao Yi. The two of them kept a very low profile.

Not long after, Xiao Yi followed Qin Changfeng and arrived at a house in the deepest part of the alley with familiarity.

This was a small courtyard with the most ordinary exterior. However, there was a secret hidden within.

In an inconspicuous corner, there was actually a spiral staircase leading to the underground.

Xiao Yi laughed in his heart. This auction could be said to be a real "underground auction".

However, Xiao Yi was still shocked when he stepped on the stairs.

This underground auction hall actually covered an area of hundreds of square metres. The interior decoration was luxurious, the lights were bright, and there were no elegant seats. There were hundreds of sofas and chairs placed neatly on the floor. At this moment, there were almost no empty seats. More than a dozen beautiful women dressed in high open-seller gowns were carrying drinks and walking through the hall.

Moreover, there were so many people in the underground auction hall, but he didn't feel depressed at all. It was obvious that there were other clues.

Xiao Yi merely glanced at it and his heart rejoiced. He could not help but nod his head. Just from the furnishings of this auction, one could tell that this auction would definitely be extraordinary.

"Uncle Master, let's go to the front row!" Qin Changfeng whispered in Xiao Yi's ear.

"Alright!" Xiao Yi nodded and followed Qin Changfeng to the VIP seats in the front row.

As soon as Qin Changfeng came over, countless people got up and greeted him respectfully.

Qin Changfeng, who was either close or distant, responded flexibly. Finally, he sat down with Xiao Yi.

"Master Qin, you're here, too?" As soon as Qin Changfeng sat down, a surprised voice came from the back seat.

Xiao Yi glanced slightly and saw a slightly fat young man in his twenties sitting behind Qin Changfeng. He was wearing famous brands from head to toe, and every detail of his body was extremely delicate and luxurious. At first glance, it could be seen that this young man was extraordinarily wealthy.

Next to him sat a beautiful woman in a long red dress. Xiao Yi found her familiar. Although he couldn't name her, she was a star who could often be seen on television or on billboards. Otherwise, Xiao Yi wouldn't be familiar with her.

The woman was wearing bold avant-garde clothes and had exquisite makeup. She was holding the young man in her arms, and her chest was tightly attached to the man's arm. There was a look of unconcealed excitement in her eyes. Obviously, this was the first time she had attended this mysterious underground auction.

"Mr. Wang!" As soon as Qin Changfeng saw the young man greeting him, he also smiled and gave a bland response.

"Haha, I didn't expect that I was so lucky this time. I came to the auction randomly and met you!" The young man whom Qin Changfeng called Mr. Wang was extremely excited because he could meet Qin Changfeng.
