Lin Yu didn't have to think about it to choose the Star and Moon Crystal, because he cultivated the Seven Star Sword Technique, using the Star and Moon Crystal that contained a lot of star power, and the cooperation between them should be flawless.

"Star-Moon Crystal, hehe...... No wonder you can't take your eyes off it. Yao Xi covered his lips and chuckled, and said curiously: "Then what are you going to do? You must also have the Ming Array, right?" Yao Xi was still very interested, of course, there was no swordsmith who would not be interested in the Ming Array. Yao Xi was curious about what kind of formation Lin Yu would engrave on her sword, but there was no doubt that the formation must be higher than the flame slash level of the sword in her hand, right? Thinking like this, there was a faint expectation in her heart.

"Well, I've already figured out what to do...... Lin Yu chuckled softly.

"Oh, that's great, Lin Yu let me be your assistant...... Okay, okay?" Yao Xi said coquettishly.

"Well, no problem......" Lin Yu's face turned slightly red, because at this time, Yao Xi's plump chest was rubbing his arm, and the touch from it was soft, which made people think about it, although this girl was only fourteen years old, she was already developing very well.

Yao Xi also noticed his gaffe, and quickly let go, his face was flushed, and he lowered his head and didn't dare to look at Lin Yu, feeling that his face was hot.

"Hehe......" Lin Yu was also a little embarrassed, and said with a smile: "Let's go out......"

"Okay......" Yao Xi nodded, he actually ran out of the material room before Lin Yu, and his face returned to normal when he got outside, thinking of Fang Cai's embarrassment, his face turned red again, but there were some different emotions in his heart, at this time Lin Yu walked out leisurely, but what made Yao Xi feel strange was that this person had nothing at hand, and asked in surprise: "What about the star and moon spar? Why don't you take it out?"

"What do you take it out for?" Lin Yu asked.

"Eh, what can you do, don't you need to forge a sword after you choose the materials?" Yao Xi said speechlessly.

"Oh, the one that's not in a hurry, I want to wait a while. Lin Yu said with a smile, he also had his own plans, now his cultivation was only the Yellow Rank Fourfold, and it was still difficult to control the more complex Ming Array, so he decided to cultivate hard during this time and upgrade his cultivation to the Yellow Rank Sevenfold as soon as possible, so that he could complete his Star Sword with full certainty.

"So that's ......" Yao Xi said disappointedly, she originally wanted to see Lin Yu casting swords and learn advanced experience by the way.

"Take me to see it......" Lin Yu also saw the disappointment in Yao Xi's eyes, and took the initiative to take her little hand.

"Where are you going?" Yao Xi said with some confusion.

"Aren't you Sword Forge Pavilion going to forge swords for others? As a guest sword forger, I also want to make a contribution. Lin Yu said with a smile, Yao Wanli was willing to give away such a precious ore as the Star and Moon Crystal, although he said that he did not ask for anything in return, but Lin Yu thought that he was not cheeky enough to take it for nothing, so he decided to try his best to cast a sword for them during this time, as a way to repay the favor, so that he could also feel at ease.

"Really? Okay...... I'll take you there now......" Yao Xi swept away the gloom and ran out with Lin Yu in a hurry, and soon the two of them arrived in a sword casting room that was cleaned up.

"This is my dedicated sword casting room...... Yao Xi said with a smile, asking Lin Yu to wait, she ran out, and when she came back, she held two severed swords in her arms, and said: "This is Sister Xiangyue's Qiushui Sword, which was broken during the battle with Xiao Yang half a month ago, and she originally asked her grandfather to help her reforge it, but I think you are more suitable...... Hee-hee......"

"Chu Xiangyue's?" Lin Yu remembered last night's charm, saying that Chu Xiangyue's figure was really good.

What do you think?

Lin Yu shook his head vigorously to dispel the dirty thoughts and walked away, then took the broken sword in Yao Xi's arms, and observed carefully, the broken sword of autumn water was light blue under the background of the sun, the blade of the sword was as sharp as a star, and the fracture was very smooth, and it was actually interrupted by someone with a very strong means.

"How's that?" Yao Xi asked eagerly.

"The damage is not too serious, but the inscription array inside has been completely shattered, and there is no possibility of repair. Lin Yu saw through the key at a glance.

"What should I do then?" Yao Xi asked again.

"The original magic circle can improve the sword master's perception of the heaven, earth, and water elements in a short period of time, which can be regarded as a relatively low-level magic circle. Lin Yu said.

"Is it low-level, then do you want to engrave a more advanced magic circle on the Qiushui Sword, can you send out sword skills like my sword?" Yao Xi's eyes were full of anticipation, but Lin Yu shook his head and said: "No, in fact, the profession of swordsmith is not simple, there are many aspects you need to understand, the material and attributes of the ore itself, as well as the cultivation of the sword master, family background, background, and even the characteristics of his moves must be taken into account." ”

"En, I don't understand...... Yao Xi asked with a blinking eye, but she looked serious, she knew that Lin Yu was teaching her.

"Let's take Miss Chu as an example, first, she is a water cultivator who can sense the water element between heaven and earth very well without the blessing of the magic circle in the Qiushui Sword, so the magic circle in the sword before was a shame to be discarded, and it was really limited to her own combat power improvement. Second, it's the swordsmanship you just mentioned, Miss Chu is a well-known master in the outer gate, and he can enter and leave the library pavilion, so he naturally won't be so thirsty for swordsmanship...... Third, the characteristics of Miss Chu's moves. ”

Lin Yu remembered that he was almost slapped to death by Chu Xiangyue last night, and he was a little happy in his heart, and continued: "The master of the Xuan-level double, the spiritual power is even comparable to the ordinary Xuan-level four-fold, but ...... She can't control her spiritual power very well, so in such a battle, seven points of ten points of her strength is already the best expectation for her opponent. Can you understand that?"

"Well, why do you know Sister Xiangyue so well, and what is your relationship?" Yao Xi said coldly.

"Is this the point?" Lin Yu said with a black line in his head.

"Oh, I'm sorry......" Yao Xi realized that he had lost his mind, and hurriedly recalled what Lin Yu said just now, and said: "To be able to understand a little, sword casting also varies from person to person, a good swordsmith needs to consider all factors to create the most suitable sword for the sword master, right?"

Lin Yu nodded slightly and said, "Then you don't have to answer your previous question, right?"

"Sister Xiangyue doesn't need sword skills, according to her condition, the core of the Ming Array should be how to allow her to control her spiritual power output well, so that the power of ten can be very useful. Yao Xi smiled.

"Clever. ”

"Of course...... Don't look at who I am......" Yao Xi said proudly, and after being praised by Lin Yu, she seemed to be about to fly, and asked: "But the formation that assists the sword master to control his own spiritual power sounds very profound, will you?"

"This kind of support circle is not very difficult...... I still know a little bit ......," Lin Yuyun said lightly.

Yao Xi was so shocked that he couldn't speak, this kind of difficulty is not high, do you know something?

How much are some?

One or two?

After a long time, Yao Xi asked calmly, "May I ask how much do you know about this kind of auxiliary formation?"

"Well, five or six kinds......

Goo-dong.

Yao Xi fell to the ground, you must know that the formations used for the Ming Array are very rare, and the person in front of him has five or six kinds of mouths, and he doesn't have any breath, it seems that he doesn't care at all, after seeing Lin Yu's power, Yao Xi is convinced of his words.

"What's wrong with you, are you okay?" Lin Yu hurriedly helped Yao Xi who fell to the ground up.

"It's okay...... I was just scared by you......" Yao Xi smiled awkwardly.

"Oh, I originally wanted to say that there are more than a dozen, but I didn't say that because I didn't believe you......"

Goo-dong.

Yao Xi, who had just stood up, went down again, and Lin Yuzhi had to help her up again, but this little Lori didn't get up at all, hugged his thighs tightly, and said with teary eyes: "Lin Yu...... Take me as an apprentice, I have a good talent for sword forging, I am diligent and studious, and I am beautiful, and I can warm my bed when necessary......"

“......”
