"Guest swordsmith?" Lin Yu asked suspiciously.

"I know it's a bit presumptuous, but with your swordsmithing skills, you can definitely take on this task, and ...... It's just a name, you can come when you want to come, if you don't want to come, you won't come, and we won't force you to help others forge swords, do you think that's good?" Yao Wanli thought for a while and continued: "And I just heard that you are interested in the ore of our Wanli Sword Casting Pavilion? As long as you can become a guest swordsmith of our Wanli Sword Casting Pavilion, the materials here are at your disposal!"

Lin Yu moved slightly, he did have the intention of forging his own sword, because yesterday he went around the major weapons shop, and there were very few that could be seen, and even if there was, it was expensive, and he couldn't afford it at all, so forging his own sword was his only choice.

After thinking about it, Lin Yu said, "There is no problem in becoming a guest swordsmith, but you have to agree to my request." ”

"Please ......"

"Anything I do in the Ten Thousand Miles Sword Pavilion must be kept secret and not let anyone know. Lin Yu said softly.

Yao Wanli was slightly stunned and already knew the meaning of Lin Yu, now he Lin Yu only has the fourfold cultivation of the Yellow Order, it can be said that his self-protection ability is extremely poor, but he has a very strong sword-casting technique, if this news spreads, many people will definitely come to hear the news, and even some of them will directly take Lin Yu away and imprison him and let him cast swords for them, this is the so-called innocent and guilty of his crimes.

"I know...... There will never be a fourth person who knows about this matter. Yao Wanli nodded solemnly.

"Then thank you seniors. Lin Yu thanked him.

"Lin Yu, we will be colleagues in the future, please take care of us. Yao Xi said with a grin.

"Take care of everyone. Lin Yu also held Yao Xi's small hand and said softly.

Yao Xi's face turned slightly red, and for some reason, he felt very happy when he thought that he could be with Lin Yu often in the future, and he was even happier than completing a very perfect work.

"Maybe it's because Lin Yu's sword-forging skills are too powerful!" Yao Xi comforted himself in his heart.

"I don't know what kind of material Lin Xiaoyou needs to cast into what kind of sword?" Yao Wanli asked, Yao Xi also pricked up his ears and listened, his heart was full of expectations, just a few flame Xuantie Lin Yu could be cast into such a powerful sword, and his own sword, he should be more attentive, in this case, he would definitely use the best level, how amazing the result would be Yao Xi couldn't think about it.

"It's hard for a good woman to cook without rice, and it's really hard for me to say this now...... I want to see what materials are available before I can make a decision......," Lin Yu said softly.

"Okay, okay...... I'll take you to the materials room now, okay?" Yao Xi said with some impatience.

"Then thank you Miss Yao......"

"Don't always call me Miss Yao Yao, it sounds awkward, I'm only fourteen years old this year, and I'm younger than you, so why don't you call me Xiaoxi...... Hee-hee......"

"Okay...... Xiaoxi ......"

"Hey......" Yao Xi's face was slightly red, his heart was sweeter than eating honey, and he took the initiative to take Lin Yu's hand and take him out, Yao Wanli noticed the strange situation of his little granddaughter, he had lived for so many years, and he didn't follow as a light bulb.

Let Yao Xi pull it, Lin Yu came to this familiar place again, but the treatment is completely different, yesterday Yao Xi was very disdainful, but today he is well-behaved and obedient, the comparison between before and after makes Lin Yu feel that the world is abnormal.

"This is it...... Yao Xi pointed to a tall iron door in front of him and said, took out a bunch of keys from his chest and opened it directly, Yao Xi is Yao Wanli's favorite little granddaughter, naturally she has many privileges, and she can enter and exit at will and use the material library that has always been heavily guarded.

Pushing open the iron door, Lin Yu was surprised by the dazzling array of ores inside, when he came, he already knew that the Ten Thousand Miles Sword Pavilion was rich in heritage, and now he realized that he was wrong, and its background was far beyond his imagination.

"It seems...... I've come to the right place. Lin Yu said softly, with so many rare ores, he was confident that he could choose the most suitable one for him.

"Awesome...... Let's go ......" Yao Xi took Lin Yu's hand and didn't let go, and kept moving forward, Lin Yu was not bad, and most of the ores he saw along the way could be named, but Lin Yu was slightly disappointed, these materials were reluctant to cast swords, but Lin Yu's requirements were very high, since he wanted to tailor two swords for himself, he naturally had to be more cautious......

"What's wrong?, isn't there anything suitable?" Yao Xi asked softly when he caught a glimpse of the disappointment in Lin Yu's eyes.

Lin Yu nodded slightly, there were not many eyes to see.

"It's okay, there's more. Yao Xi blinked and said playfully, pulling Lin Yu to continue walking inside, and it didn't take long to see a rusty iron gate, Rao still gave people a heavy and indestructible feeling.

"There is actually a cave ...... the sky," Lin Yu muttered to himself, Yao Xi had already taken out the second key, and opened the door lock with two clicks very skillfully, and beckoned Lin Yu to say: "Come and help, I can't open it alone......"

"Good ......" Lin Yu put his palms against the door panel, and there was a cold metallic texture coming from his palms, I'm afraid that such an iron door can't even be opened by a Heaven Rank master, right? Lin Yu thought secretly in his heart, the two of them had to work hard at the same time to push open a crack......

"Whew...... I used to push my grandfather away with one hand when I saw him coming, it's really ......" Yao Xi wiped the sweat from his forehead and said breathlessly.

"Is your grandfather very powerful?" asked Lin Yu.

"Of course...... The master of the peak of the ground level, you say that it is not powerful......" Yao Xi said very proudly, Lin Yu was also a little shocked, last night he peeked at Chu Xiangyue and was slapped in the bath, she was just a Xuan level double, so Lin Yu could barely bear it, how strong is Yao Wanli at the peak of the earth level?

It goes without saying that it was killed in seconds. Lin Yu thought secretly in his heart, but he was not afraid, and the presence of a strong enemy in front could stimulate his fighting spirit to move forward.

The two rested for a while, continued to push the door, and finally opened it after spending a lot of effort, the space inside the iron door was much narrower than the outside, Yao Xi subconsciously held Lin Yu's hand, and with some dim light, Lin Yu could see the whole picture inside, and his pupils contracted slightly, because there was a translucent spar not far away, and the light was extremely soft.

"Star and Moon Crystal?" Lin Yu exclaimed, it is said that it is the best ore that has been transformed from absorbing the essence of the sun and the moon for thousands of years at the top of Kunlun. Turning his head to look around, Lin Yu's eyes had almost popped out.

The crimson flint stone is said to be produced in the Fengdu ghost world, and the yin qi is very heavy.

Thunder Crystal, produced in the endless Thunder Sea, is the treasure of thunder cultivators.

The rock and iron earth come from 30,000 miles underground, but in terms of hardness, there are few ores in the world that can match.

......

There are only sixteen ores in the cramped room, but each one is a gem to find, and any one of them is priceless.

"Pretty good, huh...... These are all found by grandpa when he traveled north and south, and no one has used them......" Yao Xi said with a smile.

"So precious...... Can I really choose?" Lin Yu asked, but he couldn't take his eyes off those superb ores.

"Of course, grandpa has ordered, you can use the things in the material room as you like, and...... These superb ores can only be considered to play their true role when they are in your hands!"

"Huh?"

"Grandpa has collected these things a long time ago, and he originally wanted to forge his own sword, but the level is really limited, so he stayed, stayed here, and there is no other use except for decoration, but you are different, your sword-casting skills are still above grandpa, I believe you will be able to control and create a peerless magic weapon very well." Yao Xi said very resolutely, for some reason, she had a very blind trust in Lin Yu.

"Then I'll be disrespectful. Lin Yu is not a person who twists and immediately said.

"Hee-hee, that's right...... Which one do you want to choose?" Yao Xi asked curiously.

"I want the Star-Moon Crystal ......"
