In a small secret realm.

In the gathering place of the warriors of the Yang family and the Su family, some of them are concentrating on cultivation, and there are four martial artists, who are defending the Quartet and protecting the Dharma for many cultivators.

Yang Yu laid out a defensive formation alone, and he himself tempered his sword talisman in the formation.

"Buzz!"

I saw that in that formation, one after another amazing sword intent couldn't help hovering in the air, and the space was torn out one after another black cracks.

The cyan green fire in the center of the earth was burning fiercely inside, and in it, a piece of spiritual gold the size of a fist that exuded a colorful metallic luster was scorched by the divine fire, and the impurities in it were quickly discharged.

One after another, the astonishing divine substance sprayed outward, which made people's hearts frighten.

That piece of colorful spirit gold, refined by the green fire in the center of the earth, quickly turned into a mass of colorful liquid, constantly churning and active, as if it was spiritual, and repeatedly wanted to escape.

However, Yang Yu firmly controlled the seven-colored spirit gold and did not let it get his wish.

"Integrate the colorful spirit gold with the sword intent in your body, temper it with divine fire, and warm your mind, you will definitely be able to refine a peerless divine sword, and I can wish you to kill the enemy like cutting vegetables. ”

In the middle of Yang Yu's knowledge of the sea, Yun Heng's voice came, refining the colorful spirit gold, and also having the credit of Yun Heng.

"Uh, what level of secret treasure can you refine?" Yang Yu was very surprised, this colorful spirit gold was really extraordinary, he actually wanted to escape, if he wasn't prepared, let it succeed, he said: "Ordinary secret treasure, if it is mixed with some colorful spirit gold, it will definitely be able to improve a lot of levels." ”

"Well, the fist-sized colorful spirit gold is very precious. Yun Heng nodded and said, "Even if it is a ground-level secret treasure, if you add some colorful spirit gold, it will definitely be able to improve by three grades, which is an extremely precious spiritual object." ”

"What exactly?"

"This time, instead of refining in a conventional way, change the method. ”

"What's the other way?"

"Don't depict the formation, only cultivate the spirituality of the colorful spirit gold. Cultivating with the power of the soul will be of great benefit to you, so don't waste it. ”

"Good. Listen to you!" Yang Yu nodded.

Yun Heng is an outstanding refiner, at his peak, but he has refined the secret treasure of the earth machine, and his insight is definitely extraordinary. Since Yun Heng suggested this, then there must be a reason for him, Yang Yu is very confident that Yun Heng will not lie to him.

"Integrate your sword intent into the colorful spirit gold, and refine it into the appearance of a secret treasure with divine fire, you can change it as you like, and you will definitely like it when the time comes. Yun Heng nodded in praise.

"Okay!" Yang Yu just nodded mechanically, smiling.

The divine fire was surging, refining the colorful spirit gold at a scorching high temperature, and finally turning it into a mass of metal liquid. It exudes an astonishing aura of divinity.

"Okay, it's now, fuse the sword intent. I don't know how long it took, Yun Heng suddenly sighed.

"Snort!"

Yang Yu did not hesitate, the sword qi and the swirling sword intent in his body were all refined, and then rushed towards that cloud of colorful spirit gold, as long as it could be successfully fused, it would definitely be able to shine at that time.

However, both the sword intent and the colorful spirit gold were very arrogant. They were unwilling to fuse with each other, and they developed a kind of resistance, so that Yang Yu was not able to succeed at one time.

"Boom, boom!"

The sword intent and the colorful spirit gold emitted sword qi from each other. colliding with each other, making the space unstable, and cracks appeared, which were very amazing, like two arrogant geniuses, not far from merging. Constantly fighting each other.

Colorful spirit gold is a strange metal that everyone in the world is excited about, it has its own spirituality, and it has extremely high wisdom, and it is not willing to merge with a mere cloud of sword intent at all.

And the same is true of that sword intent, because it is generated in Yang Yu's body, it is not far away from the colorful spirit gold.

The two arrogant guys collided with each other, causing the formation to emit a circle of water ripples, and that kind of energy could be crushed even by ordinary Xuan Shen.

The ripples from the aftermath of the collision made Yang Yu a little frightened.

"Sure enough, it is worthy of the name of Colorful Spirit Gold, and it is so difficult to fuse with the sword intent, but I am looking forward to the successful fusion!

Yang Yu muttered in a low voice, a slight smile on his face.

"Slow fusion, led by the soul, refining the divine fire, you must not be reckless, otherwise once you make a mistake, the two may explode at the same time, and then the gains outweigh the losses, and you may also be injured. ”

Yun Heng saw that he was a little reckless, so he reminded in a low voice.

Hearing this, Yang Yu's face changed, and he suddenly didn't dare to be so presumptuous.

He thought that as long as the two things were fused with each other, it would be considered a success, but he didn't expect that there would be so much attention during this period, if there was no guidance from Yun Heng, something would definitely happen.

He regretted his recklessness a little.

"Thanks for the reminder!"

Yang Yu's face was stunned, and he immediately slowed down the speed of the fusion of the two, and just used his soul to guide him, slowly fusing the sword intent embryo and the colorful spirit gold, so that they could accept each other, instead of blindly squeezing and colliding with domineering and reckless.

In this way, it really works.

The agitation and collision of the two has really slowed down a lot, but it is still a little difficult to integrate with each other, just like two people, and they still hate each other.

In the end, he was distracted and dual-purpose, stripped off some subtle sword intent, and slowly fused it into the colorful spirit gold, and at the same time, deprived a small amount of the divine substance of the seven-colored spirit gold and integrated it into the sword talisman, so that they recognized each other and were suitable for each other.

"It's the right way, it's a matter of time. Yun Heng whispered.

Seeing this scene, Yun Heng couldn't help but nod with satisfaction, this kid has finally learned some real refining methods, and he is worthy of being his apprentice.

Seeing that this way was right, Yang Yu couldn't help but show a satisfied smile on his face.

This process is constantly continuing, and the collision between the two is also slowly decreasing.

I don't know how long it has been, this change is getting bigger and bigger, and what is incredible is that inside the colorful spirit gold, there is a taste of sword intent, and in the sword intent, it gradually has the divine substance of the colorful spirit gold.

If this continues, the integration of the two will definitely not be a problem.

As long as the two reach a point of balance, they can be successfully integrated in an instant.

When the time comes, the colorful spirit gold is the sword intent embryo, and the sword intent embryo is the colorful spirit gold, the two are exactly the same, you have me, I have you, regardless of each other, and then fuse, it will be very easy.

The green fire in the center of the earth continued to release high temperatures, dissolving the two substances, and gradually fusing each other, although the process was very slow, but under the passage of time, it still achieved good results.

When this state lasted until the twelfth day, the physical properties of the two became exactly the same, and they did not distinguish between them.

"Melt!"

Yang Yu's heart trembled, and suddenly the two fused, this time it was extremely smooth, and it quickly merged into a dazzling colorful substance, with an amazing sword intent in it, and the two no longer struggled, but supported each other, and the two became one.

"It's done!"

Yang Yu was extremely happy, a smile of relief appeared on his face, after more than ten days, the two substances finally fused and became a new form.

"When you take shape, don't forget to add the power of space!" Yun Heng suddenly reminded.

Yang Yu was stunned for a moment, then nodded, he understood the reason for this approach, if this sword could be equipped with a strange spatial power, it would definitely be extremely amazing, and its combat power would be much stronger.

"Click!"

At the moment, he used the power of space, fused with those substances, and carried amazing energy with each other, causing pieces of spatial blades to appear in the space, combining with that new mass of matter.

The brand-new substance, the divine substance of the seven-colored spirit gold, the sharpness of the sword intent embryo, and the weirdness of the power of space, can almost be called unprecedented, and it is almost difficult to replicate.

"Formed!"

Looking at the strange mass of matter in front of him, Yang Yu used his soul as a guide to shape it into a slender sword, which was finally finalized and quickly cooled, and it exuded an amazing sword aura and the power of space debris on it.

This sword is only one meter long, narrow and thin, and it is constantly rising with colorful colors, and it looks very good.

"Kill!"

Yang Yu drank coldly, and stabbed fiercely in front of him with his soul sword.

The colorful long sword suddenly burrowed into the space and disappeared, but the next moment it appeared thousands of meters away, piercing a mountain with a diameter of several thousand meters, and then burrowed into the space again and returned to Yang Yu's side.

"Haha, it's really unprecedented, and there is no one after! There is both the sharpness of sword intent and the weirdness of space power, which is very good. Yang Yu showed an extremely pleased smile, "In the future, you will be called the 'Colorful Spirit Sword'!" (To be continued.) )
