The procedures for seeking protection from a caravan are different from those for a caravan to hire warriors. People like Nangong Yu, who pay money to seek protection from a caravan, only need to pay and get a sign. Just follow the caravan with the sign before it sets off. As for the employment procedures, this is a bit troublesome, especially when it comes to confirming identity, which is extremely strict. After all, the caravan does not allow anyone to fish in troubled waters and make a fool of themselves. With the brand in hand, Nangong Yu naturally has nothing to worry about in terms of procedures. Put the sign into the space ring, and the date for returning home has been decided. Next, it¡¯s time to go to the auction house to buy something. The level and quality of Tianxucheng's auction house cannot be compared with that of Purple Blood City and Imperial Capital. Naturally, the items it auctions are not as high-end as those of Purple Blood City and Imperial Capital auction houses. However, with a bounty of tens of millions of gold hanging on Nangong Yu's head, he did not dare to return to Purple Blood City or the Imperial Capital. ¡°Besides, it¡¯s not allowed at this time. From Tianxu City to Zixue City, it takes only one day to go back and forth, and the imperial capital is further away. It's getting dark now, and the Desert Eagle caravan will set off at two o'clock tomorrow morning, and they won't wait for anyone. However, after all, Tianxu City is a city where caravans gather, and there are still good things in the auction here. "Tianxia Auction House" is the largest auction house in Tianxu City. People of all kinds gather here from north to south, and its popularity is not inferior to the Ten Thousand Gold Auction House in Purple Blood City. There are no auctions in the world like the Ten Thousand Gold Auction House, which has a starting price of ten thousand gold. The things here range from as expensive as hundreds of millions of gold to as cheap as dozens or hundreds of gold. After all, not all the people here are big nobles like those in Purple Blood City. The things Nangong Yu wants to buy are valuable, so naturally he has to go to the most high-end auction house. ?This is the most expensive place, and you need to show a membership card issued by the auction house or show a certain amount of financial resources before you can enter. Nangong Yu casually took out a golden ticket with a face value of 10 million gold, and immediately obtained the admission number qualification card: No. 947. The person from the auction house led Nangong Yu to the so-called most high-end venue. Although the decoration of this venue was not as good as the Wanjin Auction House in Purple Blood City, it was extremely popular. The venue, which can accommodate thousands of people, was full. When Nangong Yu came in, a mutilated weapon was being auctioned on the auction table. This weapon was a broken sword with only a half-foot-long tip. The information distributed in Nangong Yu's hand showed that this broken sword was made of meteorite iron and was indestructible, capable of breaking through the defenses of powerful people in the Purple Gang Realm. Nangong Yu neither objects to nor agrees with this news. Anyway, he has never seen the defensive ability of a strong person in the Purple Gang Realm, nor has he seen the true sharpness of this broken sword. Even if this broken sword can break through the defense of a strong man in the Purple Gang Realm, Nangong Yu will not buy it, not because he thinks the price is high, but because Nangong Yu is not good at using swords at all. When at the border, Nangong Yu was good at using a spear. If there is a chance in the future to look for spear weapons used by warriors, maybe Nangong Yu will be interested. "Twelve and a half million gold!" "Twelve and a half million gold!" "Twelve and a half million gold!" Nangong Yu is not interested in this broken sword, but it does not mean that others are not interested. Someone is refreshing the bid. Nangong Yu sat down at position 947 and began to browse the auction catalog issued to him by the auction house. The order and price of items to be auctioned at the auction house are all listed in the catalogue. "The starting price of the seventh-grade elixir Ba Gang Dan is 500,000 gold!" "The starting price of the eighth-grade elixir Zhuxueguo is 200,000 gold!" "The starting price of the third-grade martial arts Overlord Palm is 3.5 million gold!" "The incomplete possession The starting price of the treasure map is 20 million gold! " Nangong Yu browsed one by one, and finally saw something that he was slightly interested in in the 32nd item, the fifth-level martial arts "Breathe Condensation Technique". Breath gathering technique is not the main combat skill, but a supplementary skill. The focus of the Breath Condensation Technique is to hide the breath. Firstly, it can achieve the purpose of hiding strength. Secondly, when used for sneak attacks, it can quietly approach the opponent. ??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? The reason why Nangong Yu is interested in this breath-condensing technique is that if someone is chasing him in the future, this martial art can gather his own breath to avoid being tracked by the opponent's induction. This is a life-saving martial art. Of course, as the saying goes, guns are easy to dodge but hidden arrows are difficult to defend against. If Nangong Yu encounters a strong opponent, he is no match for him head-on, so he can use the breath gathering technique to carry out a sneak attack. No matter what happens, when you are forced into a desperate situation by your opponent,Death is also an opportunity to save life. The auction reserve price of this breath gathering technique is not expensive, only fifteen million gold. Of course, this fifteen million gold is not expensive, especially for a wealthy person like Nangong Yu. Putting the Breath Condensation Technique aside for the time being, Nangong Yu continued to look down. At item 48, Nangong Yu looked at what he was interested in again, the seventh-level martial skill "Six Sun Blades". After practicing the Six Yang Blade, you can release the Gang Qi and turn it into a blade! This kind of attack using Gang Qi as a blade is invisible to the naked eye and is very difficult to prevent! Just imagine, if you give the opponent a blade from a distance, if the opponent doesn't pay attention, wouldn't he be directly hit? The power of this air blade is the same as the strength used by the originator. ¡°For example, Nangong Yu¡¯s basic body can produce 500 horsepower with one palm. After practicing the Six Yang Blade, the power of the air blade struck by this punch is also 500 horsepower. If the opponent takes it lightly, hehe, he will either die or be crippled. However, the auction reserve price of this Liuyang Blade is a little higher, 38 million gold! Of course, 38 million gold is not expensive for Nangong Yu, a rich man who has a cornucopia of treasures like formation stones. No matter what, this Six Yang Blade belongs to me! Nangong Yu suppressed the excitement in his heart and continued to look down. "It's a pity that Nangong Yu doesn't like these latter things. His pockets were bulging, but he couldn't find more good things. Nangong Yu felt a little disappointed, but then he felt relieved. The Tianxia Auction House is not a high-end auction house like the Ten Thousand Gold Auction House. Being able to encounter the Breath Condensation Technique and the Six Yang Blade can be regarded as a small gain. The atmosphere at the auction house continued to be lively. Things were moved onto the auction table one by one. After a period of bidding, they were moved down again. Half an hour later, the breath-containing technique that Nangong Yu expected was put on the auction stage. As soon as the beautiful auctioneer on the auction stage announced the start of the bidding, Nangong Yu directly shouted with a high profile: "Eighteen million gold!" The price of fifth-grade martial arts is generally between 12 million gold and 18 million gold. Nangong Yu didn't want to waste time on bidding. Besides, he is now a real billionaire. He only needs a small amount of two to three million gold. Naturally, he will kill the price in one bite.
