Xiao Yunchuan clenched his fists and smiled: "Senior Brother Wu, I don't know how to forge a sword, what difficulties do you have, just say it directly." ”

Wu Zong threw the half-finished sword in his hand into the bucket on the side, and said: "Chijing Xuantie is a fire attribute material, and Dragon Qimu is a wood attribute material, and the attributes of wood and fire are born together, so Dragon Qimu will be gradually converted into a fire attribute by Chijing Xuantie." Therefore, if you want to forge a sword that can accommodate two attributes, you must use the Five Elements Stone ......"

Xiao Yunchuan was curious and asked, "What is the Five Elements Stone?"

Wu Zong explained: "There is a mutual restraint between the five elements, but the five elements stone can combine the attributes of the five elements and counteract the mutual restraint between materials, so that a sword can have multiple attributes. ”

Xiao Yunchuan asked again: "Then let's find the Five Elements Stone." ”

"In my hand, I still have some Five Element Stones left, just enough to forge a sword. After Wu Zong finished speaking, he added: "If you have better fire attribute and wood attribute materials, you can give them to me, and the quality of the sword cast in this way can also be better." ”

"Senior Brother Wu, look at this fire attribute material, is it feasible?" Wu Di took out a piece of fiery red iron ore from the storage bag, after this fiery red iron ore appeared, the temperature in the room rose rapidly, and the space was scorched and distorted a little.

Wu Zong took the fiery red iron ore, took a look at it, and said in shock: "This is the Yanhuang Crystal! How did you get this?"

"I got it by chance, I wonder if it can come in handy?"

Xiao Yunchuan stood five steps away, and he could feel the heat wave coming to his face, but the two senior brothers held the Yanhuang Crystal, but they ignored it, as if they couldn't feel the temperature of the Yanhuang Crystal.

"The Flame Phoenix Crystal is the best fire attribute material, if you use this thing to forge a sword, you will definitely be able to rank among the top 100 sword shrines. Wu Zong frowned, and said, "But the quality of the Dragon Qimu is relatively low, so it can't withstand the high temperature of the Yanhuang Crystal. Therefore, if you want to use the Flame Phoenix Crystal as a sword forging material, you must find a wood attribute material that can match it. ”

Wu Di nodded, and said with a heroic smile: "Senior Brother Wu, don't worry, just leave this to us!"

Wu Zong was shocked and said, "Do you still want good wood attribute materials?"

Wu Di shook his head and said: "Ten days later, Qingzhou will hold a large-scale trade fair, I am going to take my junior brother and try my luck in the past, if I don't find a good wood attribute material, I will talk about it then." ”

When Wu Zong heard this, he said: "My senior brother's sword-forging attainments are not inferior to me at all, he happens to be in Qingzhou now, after you arrive in Qingzhou, contact him immediately, he knows that those wood attribute materials can be matched with Yanhuang Jing, take him to the trade fair, it should be able to help you." ”

Wu Di hugged his fists and said: "Senior Brother Wu, then our senior brothers will leave!"

Wu Zong waved his hand, made a gesture to drive away, and said, "Get out! Don't delay me striking iron." ”

The brothers returned to Liuyun Pavilion, took off the clothes of the Nine Heavens Sword Sect, changed into ordinary clothes, and then went to Qingzhou.

Saibei is far away, located in the northernmost part of the Tang Kingdom, and the two are far apart.

Although Xiao Yunchuan entered the late stage of foundation building, he still drove for nine and a half days before rushing to Qingzhou on the eve of the fair.

Before sunset, the two landed at the east gate of Qingzhou City, and a man in blue and white clothes greeted them.

The man's appearance was rigorous, carrying an amethyst sword box, quite a swordsman's style, and before he approached, he shouted to Wu Di: "Senior Brother Wu, I'm here!"

Wu Di introduced to Xiao Yunchuan: "His name is Mu Ziyin, he is still very young, he has been cultivating for less than a hundred years, but he is the same generation as us; ”

Mu Ziyin approached the two of them, clasped his fists and said, "Senior Brother Wu Di, after I received the flying talisman from my senior brother, I came here early to wait for you, why did you only arrive today!" After speaking, he looked at Xiao Yunchuan and felt very angry, so he asked again: "Huh, who is this brother?"

When Xiao Yunchuan heard this, he introduced himself: "Senior Brother Mu, my name is Xiao Yunchuan, and my teacher is Xiao Yichen. ”

Mu Ziyin suddenly realized: "Fortunately, I am glad to meet! It turns out that you are Uncle Xiao, the apprentice you accepted a few years ago." ”

Wu Di saw that the two knew each other, so he asked Mu Ziyin, "Why did you come to Qingzhou?"

Mu Ziyin said slowly: "A few days ago, I took over the task of the sect, but something went wrong with the task, so I stayed here. ”

"What's wrong?" Wu Di said with understanding: "It shouldn't be a small problem, right? No wonder Wu Zong asked me to contact you immediately after I arrived in Qingzhou." ”

Mu Ziyin said embarrassedly: "It's all because I am idle on weekdays and don't practice hard, but now I have to let the senior brother worry about some trouble." ”

Wu Di patted Mu Ziyin's shoulder and said, "We are fellow senior brothers, and Senior Brother Wu has agreed to help cast the sword, if you have any trouble, just say it, I will do my best to help you settle it!"

Mu Ziyin shook his head and said, "I'm not in a hurry beforehand, the trade fair is about to start, let's go to the trade fair first." ”

Wu Di nodded and said, "Okay, you lead the way, let's go over." ”

......

The mortals and monks in Qingzhou City live together, the population reaches 10 million, but the number of mortals occupies the majority, although there are monks living in the city, but the two do not interfere with each other, and they are at peace.

After all, Qingzhou City is the main city of a state, covering a vast area, although Xiao Yunchuan has been to Tianshui City and Qixian City, but the scale of those two cities is far from being comparable to Qingzhou City.

The three of them were in Qingzhou City, turning around, passing through a formation, and finally came to a golden hall.

Above the center of this hall, a night pearl is placed, illuminating the entire hall as bright as white.

Xiao Yunchuan glanced around, there were about three hundred people in the hall, and he couldn't see through the realm of most of them, at least they were monks in the Jindan period.

The three of them found a place, sat down, whispered, and chatted about some inconsequential gossip.

After a while, a middle-aged man wearing a mask walked out, he clapped his palms to attract everyone's attention, and then said: "Welcome to this fair, I am the person in charge of the trade fair here." ”

"The path of immortals is full of suffering, as monks, whether it is refining qi, alchemy, or arranging formations, there are always materials that are missing, and we also need magic weapons when we travel and explore, so I convened this trade fair, where everyone barters things and helps each other. ”

"Next, I won't delay the time of fellow Daoists......" As the middle-aged man's voice stopped abruptly, there was a lot of noise in the hall, and everyone was eager to try.
