Back in Tianxu City, Nangong Yu first went to the auction house and sold the second-grade martial arts "Eight Movement Palms". Since the auction house was not owned by the Zhao family, and Nangong Yu was eager to sell it, the martial arts book that could have been sold for two million gold was only sold for 1.7 million gold, a low price of 300,000 gold. Even though this martial skill is just an unexpected thing obtained from a bandit's lair, Nangong Yu still can't accept the price reduction of 300,000 gold. This is really too dark. Jialuo Academy spent 50,000 gold in the competition and gave Sanmei 1 million gold. Nangong Yu¡¯s net worth of 2.57 million gold was only 1.52 million gold. Even if he wanted to use the formation stone to extract the essence of the elixir to make money, Nangong Yu still had to have the capital to buy the elixir. Although low-level elixirs are cheap, the price of the purified elixir essence is probably not much higher. Only by purifying high-grade elixir can one make a lot of money. With a net worth of more than 1.5 million gold, Nangong Yu could only purchase ten eighth-level elixirs. Therefore, Nangong Yu had no choice but to pursue the second-level martial arts. After all, there is no use keeping this martial skill by yourself, it might as well be turned into money. 1.7 million gold is enough to buy eleven elixirs. The profit difference of the purified elixir essence is not only enough to make up for the loss of the price reduction, but also makes a huge profit. Now, Nangong Yu¡¯s net worth is more than 3.2 million gold, which is enough to buy twenty-one eighth-level elixirs. As for the remaining magic skills, Nangong Yu felt that they should never be sold unless absolutely necessary. Although his test at Jialuo Academy had an accident, it did not mean that Nangong Yu had no possibility of becoming an illusionist. The mental talent is excellent, which shows that Nangong Yu's achievements in illusion are not small. ¡°Besides, this illusion skill is not easy to master, and even if you have money, you may not be able to buy it. After you have completely figured out the secret of the formation stone, you can think about the illusionist again. After all, the road must be achieved step by step, and the food must be eaten in bites. No one can become fat after eating one bite. Nangong Yu came to the No. 1 shop in the world in Tianxu City. When he came, he felt that the fat man in the No. 1 shop in the world was of good character and the price was fair. Secondly, this fat man seems to be an extremely shrewd businessman. The smarter the businessman, the better he is at keeping secrets for his customers. After all, once a big customer is found, any savvy businessman will think about how he can make money by himself, so how can he let others share his financial resources. Although the purification of Nangong Yu¡¯s formation stone can bring huge profits, it cannot be mass-produced and can only be done secretly. After all, the essence of the elixir purified by the formation stone can be directly absorbed by the human body, saving time on practice. This is more powerful than the elixir, and naturally more likely to attract people's envy. Therefore, Nangong Yu had to act carefully. Originally, Nangong Yu, the second-grade martial art of "Eight Movement Palms", could also be sold at the No. 1 Shop in the World. Maybe the fat man could give a higher price. But once Nangong Yu did this, he would show his flaws in front of Fatty. Just imagine, a person who can easily take out 20 million gold, can he care about a second-grade martial arts? If Nangong Yu wants to sell the elixir essence purified from the formation stone to the fat man, he must maintain his high profile in front of the fat man, so that the fat man does not dare to look down on him. Therefore, Nangong Yu chose to sell off the martial arts at a reduced price in the auction house. Since Nangong Yu's dress and voice had not changed, and the fat man who was the storekeeper happened to be there, he recognized at a glance that the man in black robe in front of him was the big customer who had bought more than 20 million gold things from him before, and he quickly He invited Nangong Yu to the best private room with great enthusiasm and made the best tea. "Old sir, what do you want to buy?" The fat man smiled respectfully and looked at Nangong Yu. "Shopkeeper, I think you have a good character, so I want to do a business with you. I wonder if you have this idea?" Nangong Yu said in a pretentious tone. "The old gentleman is saying that you have something good to sell to me?" The fat man was very shrewd and immediately guessed what the other party was thinking. ¡°Not bad.¡± Nangong Yu nodded. "Okay, okay, okay." The fat man nodded repeatedly. For such a big customer who could easily spend 20 million gold, the things he brought out were naturally not ordinary things. In business, businessmen naturally like to resell good things, after all, this is the most profitable way. "I don't know what you want to sell, old gentleman?" the fat man asked tentatively. "I don't have this thing with me for the time being. If the shopkeeper is interested, I can pick it up immediately. But, shopkeeper, I think you should find an elixir connoisseur." "Elixir connoisseur?" The fat man was stunned. , and then he couldn't suppress the ecstasy in his heart. Since the other party asked for an elixir connoisseur, it means that he most likely has the best elixir in his hand. My dear, this is something that comes only by chance. "Okay, okay, no problem, I can hire the best elixir connoisseur in Tianxucheng!" Fat ??Nodding his head like a chicken pecking at rice. "Okay, the shopkeeper is so happy, I'll go get it right away!" Nangong Yu slapped his thigh, as if he wanted to leave quickly. After taking two steps, Nangong Yu pretended to slap his head again, "Oh, I almost forgot, When I came to your place, I almost forgot that I wanted to buy something. Shopkeeper, please bring me twenty-one phoenix grasses?" The fat man was stunned and then said politely. Sir, I'll sell you this Phoenix Grass at the previous price, which is two thousand gold per plant, or 148,000 gold per plant, for the sake of our next transaction. , I will erase the fraction of the eight thousand gold for you, just give me 3.1 million gold." "Thank you, shopkeeper." Nangong Yu couldn't help but feel more favorable to the fat man, and erased the eight thousand gold. A fraction of a thousand gold is equivalent to nearly four hundred gold cheaper per Phoenix Grass. After paying the money and delivering the goods, Nangong Yu walked out of the No. 1 shop in the world with the fat man¡¯s smile on his face. Nangong Yu found a secluded and safe inn and opened the best and most expensive room. Instruct the store owner that no one is allowed to disturb him without his permission. After entering the room, Nangong Yu did not immediately take out the Phoenix Grass for refining. Instead, he sat cross-legged and meditated, pretending to be practicing. He kept sensing the scene around the inn and found nothing unusual for the time being. After another half an hour, after truly confirming that no one was following him and that there was nothing unusual around him, Nangong Yu stopped meditating. With a thought, twenty-one phoenix grasses in the space ring appeared in Nangong Yu's palm. Under Nangong Yu¡¯s thoughts, the formation stone emits a soft light. Twenty-one phoenix grass plants quickly turned into a ball of dregs. The elixir essence of the phoenix grass was purified and turned into a red pill about the size of an egg, emitting an extremely attractive fragrance. ¡°Such a red pill must be sold at a very high price. After all, when a good thing becomes a whole, its value will be higher. Nangong Yu was selling this thing for the first time, and he didn¡¯t know how much it would be worth. However, the cost is 3.1 million gold. The effect of the pill is even more incredible than that of the elixir, and it has no side effects. The value should be doubled or tripled.
