"Is the Wuding River the largest river in the Boundless Grassland? It is said that this river was formed tens of thousands of years ago, and no one in the world knows its source. Gu Feng looked surprised.

Wuding River can be said to be known to everyone in the boundless grassland, no one knows, this river is magnificent, stretching for thousands of miles. However, the most important feature of the river is not here, but its mystery, it is said that the river has no source at all, or it is not known where it really originated, only that the water in the river gushes out of an underground cave, and it is not known where the cave leads. For countless years, there have been many talented people who have entered the world to explore, but those people have not appeared in the world since then, so over time, people have called it the river of indefiniteness, which means the river of no source.

"Yes, but this river is only a tributary of the Wuding River. The young man replied.

"I can't tell how far the Wuding River is from this city, but the fact that the founder of this cultivator alliance actually took out a tributary from the river is enough to show that this person has great courage. Gu Feng couldn't help muttering to himself, and then paid the young man a lot of spirit stones, and then he rose into the air and flew towards the other side of the river.

At this time, it was evening, and there was no one on the street, so Gu Feng walked forward for a while, and simply found an inn to rest temporarily.

Early the next morning, when Gu Feng walked out of the inn, the streets were already full of people. Gu Feng deliberately observed and found that most of them were cultivators around the early stage of Hedan, and there were only four or five hundred monks in the middle of Hedan, and there were even fewer monks in the late stage of Hedan.

Gu Feng didn't pay attention to this, just walked aimlessly on the streets, but as he walked, he always paid attention to the various shops on both sides of the street, and occasionally saw a store he was interested in.

After more than ten days, Gu Feng paused in front of a shop again and looked at the plaque above the storefront.

"Liandao Pavilion, this shop has a cold business, but this plaque has existed for many years. Gu Feng stared at it for a long time and couldn't help muttering to himself.

At this time, the ancient style looks at the place is a black plaque that is not too big, there are three words on it, the plaque seems to be made of an inexplicable wood, and now there are thin seams on the plaque, which is the best witness to the years, but the three big characters on the plaque are still undiminished, giving people a sense of strength and strength.

"The name of this shop is kind of interesting. Gu Feng muttered to himself, and finally took a step towards the store.

"Does this boy need a magic refining weapon?"

At this time, an old man saw Gu Feng entering the store, and hurriedly stepped forward to ask.

The old man seemed to be in his sixties, with a gray robe and half-gray emanation, full of heaven and spirit, giving people a sense of toughness and ability.

Gu Feng swept his eyes and found that the old man had a three-color city talisman hanging on his waist, indicating that the old man had a Hedan middle cultivation.

"Huh, how did the seniors know that I needed to refine the magic weapon when I came here?" Gu Feng was slightly stunned when he heard this.

"Childe don't have to be confused! The old man's shop is dedicated to refining magic weapons for people, so everyone who enters this shop, the old man will ask the same question. Could it be that Childe really came here to find someone to refine the magic weapon on his behalf?" the old man explained with a wry smile, but in the end, his eyes lit up, and he looked at Gu Feng expectantly.

"I see! The purpose of coming here is indeed to let your shop help refine a magic weapon in the next place. Gu Feng showed a clear look, and then replied frankly.

"I don't know what kind of magic weapon Childe wants to refine, and what kind of material do you want to use as a material? Childe can rest assured! As long as Childe has the right materials, the old man will definitely refine a magic weapon that satisfies Childe. The old man didn't feel excited when he heard Gu Feng's words, and then hurriedly asked, and assured Gu Feng with confidence.

"Oh, the self-confidence of the seniors is very admirable, so the juniors are blunt. The junior came here this time to use the flesh of these alien beasts as materials to refine seventy-two identical combination flying swords. ”

For some reason, Gu Feng suddenly had an inexplicable good impression in his heart when he saw the old man, so he simply handed the storage bag directly to the old man, and in the storage bag were the flesh of many strange beasts from the ancient land. Of course, it is not the flesh of the beast, but the parts of the body with special materials, such as the crocodile armor of the giant crocodile at the bottom of the swamp.

The old man hurriedly took the storage bag and probed a wisp of divine sense into it.

"This ......"

As a result, the next moment, the old man's face suddenly showed a look of surprise.

"Do you think this is feasible?"

In fact, Gu Feng had already expected the performance of the old man, there were dozens of foreign beasts he killed in the ancient land of Xiuyuan, and the storage bags of the two late Hedan monks were even more alien beast materials, on the other hand, most of the foreign beasts lived under the protection of the God and Demon Sect, and it was really difficult and difficult for ordinary monks to obtain so many foreign beast materials, so it was normal for the old man to be surprised.

"Naturally, you can! But these materials are all from the body of a strange beast, although they are all high-grade materials for refining weapons, but if you simply use this refining tool, you may not be able to practice a truly high-grade magic weapon. Personally, I have some precious metal materials, so I will simply add them to these beasts. ”

The old man was very excited, and he responded to Gu Feng's question, but the next moment his face was contemplative, and after a long time, he seemed to grit his teeth, and finally added to Gu Feng again.

"Okay! If that's the case, it couldn't be better! I don't know how the seniors get paid for refining the magic weapons?" Gu Feng was also happy when he heard the old man's words, although he didn't know much about refining weapons, but he understood the truth in the old man's words.

"Seventy-two combined flying swords...... The old man can't remember the last time he refined a magic weapon of such difficulty! Now that you've given me another chance to enjoy it, it doesn't matter if I spend some time on it. As for the reward for refining, I don't really have any standard, it's all up to the child's own wishes!" the old man checked the materials in the storage bag again, and then said with emotion.

Gu Feng's heart throbbed when he heard this, and he always felt that there seemed to be a vicissitudes in the old man's words, and even gave him an unfathomable feeling.

"The juniors understand! Then when the seniors finish refining the seventy-two swords, all the remaining materials will go to the seniors! First, to compensate the seniors for consuming treasures for me, and secondly, to treat them as the remuneration of the seniors for my refining weapons. Gu Feng said after a little thought.

Most of the materials in the storage bag are made by others, so they are not very precious to the ancient style.

"Then the old man will thank Gongzi! These seventy-two flying swords will be used by the old man with all his strength, but the refining process will probably take a lot of time, and Gongzi may need to wait for the next year. The old man spoke again.

"That's okay, I'll wait a year, and I'll visit again at this time next year." Gu Feng replied without thinking.

"The son can trust the old man, then we will agree for a year, and I will definitely present the seventy-two swords in both hands at this time next year. The old man smiled back.

"Okay! Then the junior will take his leave first. After saying this, Gu Feng saluted the old man respectfully, and then turned around and walked towards the outside of the store.

"The last time I refined such a complex magic weapon, was it four thousand years ago or five thousand years ago...... It looks like I'm really getting old. Gu Feng had been away from the shop for a long time, but the old man suddenly said to himself, and then stood still again for a long time before taking the storage bag and walking towards the inner room.

In the evening, Gu Feng found an inn again, and rented a temporary cave mansion with a fairly strong aura for dozens of medium-grade spirit stones, obviously planning to live for a long time.

A moment later, Gu Feng was already meditating cross-legged in the cave, but in his right hand was holding a shabby scroll, and he looked at the scroll with a faint smile.

The scroll is grass yellow, about a finger thick, the first page of the book has the text of three apricot kernels the size of "Sacrifice to the Immortals", and the rest of the pages are full of dense text, and occasionally there are a few slightly scribbled illustrations.

"This 'Immortal Sacrifice Technique' is really magical, most of it was created by a Instrument Sect Master! If that senior in the Refining Pavilion's Refining Pavilion can really complete the refining of the seventy-two swords, then I can try to refine the flying sword with this technique. ”

"Judging from the thirteen flying needles and the five-sided wooden card magic weapon driven by that late stage monk of Hedan, this method is mostly feasible, I really want to know how powerful the seventy-two swords are against the enemy together, I should definitely not be disappointed. Gu Feng muttered to himself as he flipped through the scroll in his hand.

The scroll in Gu Feng's hand was obtained from the monk of the late stage of Hedan who chased and killed Mu Nuo'er, and Gu Feng was surprised when he saw that monk using a combination of magic weapons, and it was also for this reason that when Gu Feng subdued the monk, he would deliberately take away his storage bag.

Later, Gu Feng took advantage of his leisure time to check the storage bag, and the result was really pleasantly surprised, because there was an ancient scroll called "Sacrifice to Immortals" in the storage bag, which told about the secret technique of sacrificial refining combination weapons.

As for why the seventy-two swords were refined, there were two reasons: first, Gu Feng was a sword cultivator, and the flying sword had a special meaning for him;

"Now that the sword refining matter is over, it is time to think about it next. The next moment, Gu Feng put the scroll away, and a jade slip appeared in his hand again, which was obtained from Akihaju's "Scroll of the Brahman War".
