Heavenly Sword Country, Ten Thousand Sword Peak, Sword Sect.

Shi Chen sat cross-legged, his hands in front of him, and turned the spiritual energy of the heavens to instill his body, and the true qi in his body flowed, running the muscles and veins of his body.

The aura around him surged, the light on his body flickered, and his face showed a look of pain.

I don't know why, the pure essence of Baihua that was stored in the body before is now showing signs of leakage, as if it is about to break out of the body at any time.

His veins were torn apart by the impact, and the pain was as unbearable as if he had been cut by a thousand knives.

"Hmm......" Shi Chen let out a muffled snort, and then couldn't suppress the churning sensation in his body, and spurted out a mouthful of blood.

From the stomach to the mouth, it is full of fishy sweet smell.

What a damn ......

This situation was just like when he broke through the twelvefold realm in the past.

The difference is that this time, the veins seem to be becoming fragile and narrow, and there are some signs of madness.

If I continue to practice forcibly today, I am afraid that it will really be a catastrophe...... Shi Chen shook his head and didn't dare to practice anymore, so he got up in his clothes and walked out of the practice room.

His steps were heavy, and he felt only a feeling of fatigue all over.

As soon as he walked out of the door, a waiting disciple stretched out his hand to support him.

"Master......" As soon as he saw Shichen's face, his whole body trembled with fright, as if he had seen a terrible evil spirit.

Damn this, don't I just have some prostration, I need to make such a fuss, it's like Lao Tzu is going to die.

Shi Chen was very dissatisfied, and said angrily with anger in his eyes, "What's the matter? ”

As soon as the words came out, Shichen's heart beat violently.

Because the voice was very old, like a dying old man.

How can it be?!

"Leader......" The disciples' voices trembled.

"Bring the mirror."

The disciple hurriedly ran away, then found a mirror and handed it to him.

The mirror reflected a bright light in the sun and fell on the rocks beside it.

Shichen's hands trembled for a moment, and he suddenly dared not look at it.

The disciple shrank aside, only daring to look at him secretly from the corner of his eye, and fine beads of sweat were already oozing from his forehead.

Shi Chen took a deep breath, calmed down for a moment, and then held up the mirror—

"No!"

With a flip of his wrist, the mirror fell to the ground and shattered with a thud.

Because, he saw a middle-aged man's face in it just now, with gray temples and fine wrinkles on his forehead, which was almost like him some time ago, as if he had returned to when he was forty years old.

Although I already felt that it was wrong when I was practicing before, when I saw it with my own eyes, I still couldn't believe it.

He suddenly remembered what his senior brother Qing Buliang had said before, the twelvefold realm is very dangerous, if you are not careful, you will go crazy, your body will degenerate, and then you will become as old as before from young.

As soon as it was dark, the whole person was about to stand unsteadily, but fortunately, with the support of the disciples on the side, he did not fall.

He was puzzled in his heart, this body had lived for one hundred and eighteen years, and he didn't know if there was enough time for him to evolve to the next level.

How many people died because their life cycle was not long enough and they didn't stick to the twelvefold realm, so the twelvefold realm is a huge watershed for the top sword immortals in the world.

Twenty years ago, he broke through this realm at the age of almost 100 years, thinking that he would be able to enter a new palace from now on, and no longer have to worry about his limited life.

didn't expect this to happen.

"Damn impostor, I've lowered my level!"

The hour looked up to the sky and roared, and his appearance was extremely hideous.

Anyone who sees it looks like he's going crazy.

"No, Hao Nan, in order to return to the Twelvefold Realm, I have to retreat and practice for three months, and you help me act as the head of the sect for three months, and within three months, don't let anyone disturb me."

"It's the boss." The disciple swallowed a mouthful of saliva with difficulty, and looked at him worriedly, "But the master, in a while, it will be the time of the Dragon Ball War, if the Sword Sect does not participate, I am afraid it will attract criticism, and the name of the first sect in the world ......"

"Little bastard! Do I still need your reminder? The hour roared.

Dragon Ball Battle can be said to be a martial arts tournament around the world, where each sect and faction will send masters to participate in the competition for the title of the first in the world.

For more than 40 years before, due to Qingbuliang's martial arts and continuous hegemony, the Sword Sect has always been firmly on the throne of the first sect in the world.

As soon as Qing Buliang died this time, various sects were ready to move, and the new round of Dragon Ball War, which was supposed to be a good time for Shichen to fight and stand strong, has now become a roadblock in front of him.

He couldn't help but be afraid.

It was then that his eyes flickered, and a bold idea came to his mind.

……

At first, Emiya was still trying to study the key material with a single attribute, but after Cui Xiaoxiao's reminder, he revised his idea again.

For example, the piano uses the principle of mechanics, whether it is an adult or a child, when you hit it, the sound of the same key is the same.

The previous Yiqin Sword used [True Qi] to directly hit the sound piece every time.

The principle of attribute conversion is to convert the [True Qi] of the same system into the True Qi of multiple types, so that it can be used to stimulate the sound.

What Wei Gong has to do now is to reverse it, so that the [True Qi] of different departments can be transformed into the same thing that can stimulate the voice.

This kind of thing is the simplest, most basic force.

Just like a steam engine, Emiya only needs to add a starting device to the end of the hilt of the sword to create the air flow in the corresponding position, and then push the hammer to strike the sounder.

One thing the operator only needs to figure out is how much True Qi should be used in what position to complete the corresponding musical operation.

The entire sword body, including the two resonant wings, can be made of the same material, and then the hilt can be equipped with seven different types of [engines].

Since the materials used in the sound generating equipment are all the same, there is no problem of excessive timbre differences.

Now that the principle has been figured out, this matter has become much easier, and it is relatively easy to do it if you do not pursue the other attributes of the sword, such as attack power, flight speed, etc., and instead focus on the tuning of the sound.

After about four days, Wei Gong had already completed the debugging of the fire-type winged qin sword and the wood-type winged qin sword.

Cui Xiaoxiao crossed Erlang's legs and listened to Wei Gong show the tone keys of the two swords one by one from low to high.

When the last note was played, the entire sword-forging room fell silent.

"How?" Emiya looked at her nervously.

"It's okay." Cui Xiaoxiao clasped her hands, pouted and nodded.

"What do you mean?" Emiya's eyes narrowed.

"It's just that you've made it."

"Hold the grass, why don't you just say this?!" Emiya rolled two big eyes.

"It's none of my business, I'll have to study the human body first." Cui Xiaoxiao stood up.

"Go, go, go."

Emiya waved his hand, then rested his right hand on his chin.

The sample was tested successfully.

Then it's time for pricing.

A strange smile appeared on his lips, and he could almost see the large amount of money waiting for him in front of him.
