Zhu Yao didn't stay outside for long, and after telling Yuluo to teach Yueying to practice, she returned to the lava cave and began to work on ironwork day after day. Originally, she thought that forging was a simple matter, especially for her in the transformation stage, but in fact, she found that it was not like that at all. The forging of magic weapons is not only possible with spiritual power. The first semi-finished products she forged were basically scrap.

Only one still retains a trace of aura, but at most it can be used to ward off ghosts and exorcise evil spirits, and it is a joke to use it to ward off enemies. Zhu Yao was a little frustrated, obviously knocking harder than anyone else, but the result was worse than anyone else.

If the exercise equipment is compared to education, she is now at the kindergarten level at most.

"Master, why is this happening?" Obviously, she has worked so hard.

"Each material has its own properties, and so do ritual weapons." Yu Yan explained lightly, "The spiritual power absorbed by the material is also limited. ”

"You're saying that you have to use spiritual power of the same attribute to create the appearance of a magic weapon."

"Yes and no." Yu Yan continued, "The key depends on what kind of magic weapon you want to practice it into. ”

In other words, if it is a flying magic weapon, it must have enough wind spiritual power, and if it is a water attribute magic weapon, it must have water spiritual power.

"I see."

Zhu Yao began to smelt another piece of dark iron again, but this time she was no longer beating wildly like before, but only condensed a trace of wind spiritual power, and with each beating, it was shattered into the magic weapon. But the strange thing is that although the wind spirit power has been passed on. But very little is absorbed by iron.

Zhu Yao guessed that it was also related to the speed at which this piece of iron absorbed spiritual power, so the second time, she reduced the output of spiritual power. Sure enough, the spiritual power absorbed this time is the same as last time.

This time Zhu Yao spent four or five times more time than before, and he repeated smelting many times in the middle.

Holding the embryo shape that had already been forged, Zhu Yao could feel the abundant wind spiritual power on it. Zhu Yao can finally move on to the next step, carving the formation. Formation is her strong point, a flying magic weapon, naturally there must be a flying formation. This time, Zhu Yao was no longer greedy, and only engraved a formation into it.

Instantly, on the embryo of that flying sword. The aura that was still overflowing just now. Suddenly converged, and was firmly locked in by the formation, and the wind aura in the air also had the meaning of faintly getting close to the sword.

The final step is to polish and shape. Zhu Yao did not take it lightly. Follow the trajectory of the formation. On the premise of not damaging the aura, slowly polish the smooth sword body.

Finally, her first weapon took shape.

Zhu Yao was a little excited. This must be the first finished weapon she has made, although it is only the most basic flying sword, and she will show it to her master.

Yu Yan squinted his eyes slightly, scanned the sword's body, and finally squeaked, "First order, lower grade." ”

"......" Zhu Yao's glass heart suddenly shattered, and the self-confidence of the apprentice who said that he was good.

Forget about the first-order magic weapon, anyway, the flying magic weapon, the first-order can go to the sky, and she doesn't have much expectation. But the next grade......

Damn, she doesn't believe that she can't make a high-level magic weapon.

Zhu Yao re-invested in the crazy upgrade of life skills, and had already captured the correct training method, and Zhu Yao's next calcining power increased significantly. It wasn't until she could finally refine low-grade Xuaniron into a second-order inferior magic weapon that she gave up this material and began refining a more advanced material.

The days have been spent in this kind of knocking and beating, Zhu Yao believes that practice makes perfect, she has also found some clever doors, and when she carves the formation, she can already carve into two formations at the same time.

I don't know how long it took, when she was refining a cold ice stone that could make up to a fifth-level magic weapon, she suddenly found that every time she entered the material's aura, it was actually distributed in a line shape, and with each refinement, there were more and more lines in it. When she forged it to a normal level, she found that the thread was not half covered with the material.

This is a surprise, could it be that after the thread is filled, it is the limit of the spiritual power that the magic weapon can hold? After having this idea, Zhu Yao did not stop refining, but continued to output it inside, allowing the spiritual power to slowly fill up.

The phantom floating on the jade pendant felt the strangeness of the apprentice, glanced at the background she knew, the corners of her mouth twitched slightly, and finally understood. Sure enough, it was his...... Well, whatever.

Zhu Yao excitedly filled the entire piece of iron with aura, thinking that this time he would definitely create an incredible magic weapon. She failed.

The material is ruined.

Because she found that the aura was full, but there was no place to carve the array! And she also thought of the grinding link later, if she accidentally broke a little, the aura inside would be scattered because of a small gap.

She only cared about putting more spiritual energy into it and improving the grade of the magic weapon, but she didn't expect this at all, ○| ̄|_.

No matter how spiritual energy there is, without formation traction, it is just a piece of scrap metal. Good luck to the heart.

A little sadly, he gave up this aura-filled ice stone. She took out the same material again and continued practicing.

This time, she didn't blindly input the aura, and arranged it in a line. She drove her spiritual power to the sides, leaving a place for the carving array in the middle. Although there is less aura now, she has spent more time, and the input of aura is a big project, not to mention that after entering the spiritual power, arrange it according to her own ideas.

For the first time, Zhu Yao felt a little powerless. It took a lot of effort to arrange the spiritual power. When it comes to the engraving formation, it is much simpler. It's just that when it comes to polishing and forming, it's another problem. No matter how careful she was, there was still a small gap, and the aura instantly dispersed.

Zhu Yao felt a pain in his flesh.

Finally, after more than ten failures, she made a successful work, although it was only a fourth-order magic weapon, it was a top-grade one. Sure enough, hard work will be rewarded. The next estimate will be able to make the best.

When she was about to continue her efforts, she found that she had run out of icestone. She could only use another black ore of the same grade as it. But when she was forging, she found a big problem, the threads that represented the aura were missing.

Flip the table, so how to play?

Zhu Yao took out all kinds of materials and tried them one by one, except for the cold ice stone, there was really no such spiritual power line.

Zhu Yao was a little dumbfounded, and took several deep breaths before calming down and thinking about the reason. It stands to reason that the materials of these tools can withstand spiritual power, but what is the difference between the Ice Stone and others? When you think about it, it doesn't seem to be any different except for the color.

Color? Is it because the white color is more transparent and you can see it more clearly? Hehe, no kidding.

Zhu Yao himself didn't believe it, if he said that, the other stones couldn't be seen with the naked eye, and his divine sense was ......

I'm K, my mind can really see.

Isn't the reason so simple and crude?

What kind of Zhu Yao was so panicked just now that he was a little speechless. silently picked up the hammer and let go of his divine sense, and continued to line up.

The higher the grade of the artifact, the higher the spiritual power required, and the more time it takes to waste. Originally, Zhu Yao still felt that he had the cultivation of the Transformation Period as a foundation, and it was simply trivial to input such an aura. Until the first time her spiritual power was exhausted, she still held a half-forged sixth-order magic weapon in her hand.

Only then did she realize how energy-consuming life skills she had been disvalued. I had to meditate to regain my spiritual power.

And there were more and more such things in the back, and when she was finally able to make an eighth-order magic weapon, she had exhausted the spiritual power of her whole body twice. She finally understood why everyone needed to retreat at every turn when they practiced Dan exercises. In the case of this kind of spiritual power being exhausted, if you are still hanging around outside, you will be the object of every minute.

"Master, it's out of stock." Zhu Yao glanced at the storage ring, and the large amount of materials piled up in it had now been consumed by her. However, she had just been able to practice an eighth-order magic weapon, and it was still a low-grade weapon.

Yu Yan frowned, and said slowly after a while, "You can smelt the magic weapon inside." ”

"The artifact inside." Zhu Yao glanced at the ring on his hand and opened his eyes wide, "Master, you can't be referring to the pile you practiced, right?" ”

Nod!

Zhu Yao instantly wanted to flip the table, those were all above the eighth order, and most of them were tenth-order magic weapons. It's just smelted, you loser.

Yu Yan looked calm, those things were originally materials, but he was idle and bored to practice, and it was very appropriate to reply to the materials.

"Is it really going to melt?"

"Hmm."

Oh~~ Her flesh hurts, she is not even willing to throw away that first-order flying sword, Master, why are you so proud?

Zhu Yao thought about it for a while, his cultivation skills had to be improved, but he had to melt down these high-level magic weapons......

After hesitating for a long time, Zhu Yao picked out a few pieces with trembling hands, and began to melt them compared to the magic weapons that were a little bit secondary. While melting, the blood is dripping. It was because of the in-depth training of the weapons that she could see how precious these magic weapons were.

Let's not talk about the materials, let's just say that the subtlety of the formation on it is not much simpler than the mountain protection array that she can't understand. It is a perfect magic weapon that completely integrates the five systems of attack and defense, and some even have storage functions.

Oh, the flesh hurts.

Maybe because of the guilt of ruining the best magic weapon, Zhu Yao was more attentive to the practice in the back, although there were also relatively low grades, but fortunately there were no waste products.

She was already able to engrave dozens of different formations on it. The magic weapon he practiced also broke through to the ninth order.

When the magic weapon in the ring was almost consumed, she finally practiced the tenth-order magic weapon. Although it is still inferior.

Zhu Yao felt that it was time to stop and get down to business, and said his original thoughts.

"Master, I want to make a special magic weapon. Need a particularly smooth material, what do you think would be the best thing to use? (To be continued......)

PS: Don't worry, I'll be back soon. Miss me.
