"This is the Four-sided City?" Looking at the magnificent city in front of him, Fang Chen wiped the sweat on his forehead and asked.
"Yes, yes. Master, let's enter the city quickly." Thunder Kid urged.
"Thunder Kid, enter the Returning Yuan Sword to avoid unnecessary trouble." At this moment, the spirit of the weapon suddenly said seriously.
Seeing Thunder Kid looking at him pitifully, Fang Chen couldn't help but touch his nose and pretend to be thinking about something. Only after Thunder Kid reluctantly entered did Fang Chen ask in surprise, "Can living things enter the space of the Returning Yuan Sword?"
"Thunder Kid is not a living thing."
"Um..." After an awkward smile, Fang Chen walked towards the Four-sided City.
"Entering the city? One low-grade profound crystal!"
Just as he reached the city gate, the guard blocked his way. Hearing this, Fang Chen threw out a low-grade profound crystal and then swaggered into the city.
Fortunately, when he was in the Sword Sect before, he had saved a lot of profound crystals. Although there wasn't even one medium-grade one, there were still more than a hundred low-grade ones. Looking at the lights gradually lighting up in the city, Fang Chen looked around and walked straight towards a restaurant.
"Welcome, sir!" As soon as he reached the door, the waiter of the restaurant came out to greet him. After Fang Chen casually threw a low-grade profound crystal, the enthusiasm on the waiter's face instantly became even stronger.
"A room. Send the meals to the room."
"Okay!"
After saying that, the waiter led Fang Chen to the room and then quickly left. After a while, he came to the room again with the meals. "Sir, here are your meals."
"Put it here." After Fang Chen sat down at the table, he threw out another low-grade profound crystal.
"Thank you, sir. If you have any orders, just say so."
Fang Chen smiled slightly and looked at the waiter and said, "I've heard of the reputation of the Four-sided City for a long time. But today, I didn't find anything special. Tell me, what's different about this Four-sided City from other places."
"This sir doesn't know. Because of the profound crystal mine, the Four-sided City doesn't have a city lord. Instead, it is jointly managed and controlled by four big families. Among them, the Wan family is the strongest. Although the Ye family, the Lin family, and the Wang family are slightly weaker, the difference is very limited."
"Oh? The profound crystal mine?" Hearing this, Fang Chen asked.
"The reason why our Four-sided City is famous far and wide is precisely because of this profound crystal mine."
"Tell me in detail." Fang Chen's eyes showed a glimmer of interest.
Seeing this, the waiter's face was full of pride, as if this profound crystal mine belonged to his family. "Except for the direction where you entered the city, the other three directions are all profound crystal mines, surrounding the entire Four-sided City."
"Oh?" Although he had already expected that the profound crystal mine wouldn't be small, when he knew that the profound crystal mine was so large, Fang Chen was still surprised. "If that's the case, then the common people in your Four-sided City must be extremely wealthy."
"Sir is joking. This profound crystal mine is firmly controlled by the four big families. As for ordinary people..." At this point, the waiter shook his head with a bitter smile.
After pondering for a moment, Fang Chen asked, "Is there an auction house in this Four-sided City?"
"Yes. The auction house is in the middle of the Four-sided City. The tallest building is it. However, this auction house is only opened once a month. The auction list will be announced ten days before each opening. If you are not going to auction something, then you need to pay an expensive fee to enter."
"Like this. How long until the next auction house opens?"
"Coincidentally, the auction house will open in three days." Remembering that Fang Chen was so generous with his spending, the waiter then asked, "Sir, if you need the auction list for this time, I'll go get it for you right away."
"Okay."
Before long, the waiter brought over the auction list for this time. After Fang Chen took a quick look, he heard the spirit of the weapon exclaim in surprise, "Taiji Returning Heaven Jade?"
"Is it very rare?" Able to surprise the spirit of the weapon, Fang Chen's interest was instantly piqued.
"This is the most crucial thing for refining the Life-Extending Pill." The spirit of the weapon said.
"But this is a jade. How can it be used for refining pills?"
"You wouldn't understand even if I told you."
"Um." Fang Chen touched his nose and smiled embarrassedly. Then he pondered and said, "It seems that this auction house is a must-go."
There was nothing to say overnight. After relaxing his mind, Fang Chen had an extremely good sleep. It wasn't until dawn when the waiter brought breakfast that Fang Chen woke up.
He got up, washed up, had breakfast, paid for three days of accommodation and food, gave some instructions, and then walked towards the city.
Along the way, Fang Chen walked and looked around but didn't find anything rare. After a long time, the building that the waiter had mentioned finally appeared in front of him.
Fang Chen stopped and looked for a moment. Then he strode towards the building. Before long, five vigorous and powerful characters appeared in front of him. Shengtian Auction House!
What a grand gesture! The signboard is actually carved from medium-grade profound crystals! After taking a look, Fang Chen walked into the auction house.
As soon as he entered the auction house, a female attendant came over. "Are you here to buy or sell something, sir?"
Looking at this female attendant in front of him whose smile and tone were both perfect beyond reproach, Fang Chen said with a faint smile, "Sell something."
"Please follow me."
After saying that, the female attendant led Fang Chen to the second floor. After walking to a window, she nodded at Fang Chen with a smile and then left.
"Is this the place to sell things?" Fang Chen asked politely.
"Ordinary things? Or things for auction?" The old man inside the window was studying something on the table. Without looking up, he asked.
"Auction." Fang Chen said without caring at all.
"Next month." The old man still didn't look up.
"Next month might be too late. I will leave in three days." After saying that, Fang Chen took out a box of extremely rough texture from his bosom.
Immediately, a faint medicinal fragrance spread out. The old man inside the window was stunned. Then he suddenly looked up at Fang Chen and said, "Is there a Six-Turn Marrow Washing Pill in this box?"
"That's right." Fang Chen responded and then handed the box in.
Seeing that the box containing the Six-Turn Marrow Washing Pill was so rough and was obviously made casually, the old man couldn't help but give Fang Chen a reproachful look. Then he found that the owner didn't seem to care about this Six-Turn Marrow Washing Pill at all. His heart was shocked. In a gentle tone, he said, "Such a precious pill. I can't make a decision. Please wait a moment, sir."
After saying that, the old man picked up the bell on the table and rang it. Then he said something to the female attendant who came over. After that, he looked at Fang Chen again with an apologetic smile.
Before long, another old man came over. After taking the pill and studying it carefully, he was shocked and said, "It's actually a top-quality Six-Turn Marrow Washing Pill?!"
After saying that, as if unable to believe it, he looked at it carefully again. Only then did he look at Fang Chen with a hint of reluctance. Just as he was about to speak, Fang Chen took out two more boxes and handed them over.
