After the small golden sword came to his senses, Yang Xie did not know where it came from. He only saw that the sword did not make any unusual movements, so he did not pay too much attention to it.

What made Yang Xie even more shocked, was that after the small golden sword absorbed the auric essence, it actually gave birth to a mysterious connection with him.

It was as if with just a thought, the small golden sword would break through the sky and appear!

"What's going on? Why does the small golden sword feel like it has a connection with its own heart after absorbing the auric essence? "

Yang Xie was secretly shocked, he suddenly remembered that the small golden sword looked somewhat similar to the cardiac sword embryo depicted in the rumors. His heart stirred: "The cardiac sword embryo's physical form is formless, it seems real and illusionary, the small golden sword description is exactly the same, could it be that this sword is the legendary cardiac sword embryo!?"

The more Yang Xie thought about it, the more he felt that the small golden sword could have been the cardiac sword embryo, and at that time, the small golden sword he had obtained was the senior from the My Sword Sect. That person was also from the My Sword Sect, so it was extremely possible that he had refined a Core Flying Sword, and this sword might even be the cardiac sword embryo that the person formed!

"If this sword is really the cardiac sword embryo condensed by that senior, I wonder which senior has been refined for how many years?"

Feeling the terrifying energy coming from the small sword, Yang Xie was extremely shocked. Previously, when he had obtained the small sword, he had felt that the energy inside was extremely terrifying, even though his cultivation had increased by a lot, and his strength was much stronger than before, he still felt that the moment this sword erupted, he would still not be able to escape death.

It was so condensed that it was almost no different from a real sword. This kind of sword embryo would take dozens of years to form!

What he did not know was that this cardiac sword embryo was formed by the elder of the My Sword Sect who had spent a whole hundred years of time to condense it, and was left to be used to refine Core Flying Sword in the future. However, before the elder could even refine the Core Flying Sword, he died in the hands of the devil and in the end, gave Yang Xie an easy death.

I originally wanted to condense my sword embryo, but I've already spent a lot of time and time preparing." I originally wanted to condense my sword embryo, but I've already spent a lot of time preparing. This sword embryo was incomparably solid. It had been refined for at least several decades! Furthermore, it was refined by a Divine Appearance Realm expert. The power of the sword is so strong that there might not even be a few of them in this world. It just so happens that this sword embryo can be used to refine a flying sword made from heart essence!

Yang Xie's heart thumped, thinking about the sword embryo that had been refined by the Sage Stage powerhouses for many years, it's power must be hard to predict.

As a result, not only did he not waste tens of years of time, he was also able to obtain a powerful Core Flying Sword, which made him ecstatic.

"There's no time to lose, I will refine this cardiac sword embryo thoroughly and then refine it into a Core Flying Sword. This way, I will have even more confidence to travel to Leng Jia!"

Thinking about it, Yang Xie did not dare to hesitate, and continued to draw auric essence from the tai-black iron and pour it into the cardiac sword embryo.

After the senior from the My Sword Sect died, the cardiac sword embryo became ownerless. As long as Yang Xie slowly refined it, he could turn the sword embryo into his own sword embryo and refine it into Core Flying Sword.

In these ten days, Yang Xie had continuously drawn auric essence and fused it into the cardiac sword embryo. Originally, he expected that it would only need half a piece to refine the Core Flying Sword, but the sword embryo was simply too powerful, and just refining it would cost almost half of it. After refining the Core Flying Sword, the tai-black iron was probably gone too.

The promise he had made earlier to only use half of it seemed impossible now.

In regards to this, although Yang Xie felt helpless, but after considering the importance of refining the Flying Sword, he had no choice but to use all of the tai-black iron. As for the half that he promised Tang Kuan, he could only think of a way to repay him in the future.

At this moment, although the small golden sword was still only the size of a palm, it had a metallic luster to it, making it look more and more like a real small sword. With a light stroke, a sharp sword aura burst out, leaving a deep and shallow mark on the ground.

With regards to the might of the sword, Yang Xie was naturally extremely satisfied. He believed that once the Flying Sword was able to refine it, the sword would be even more powerful, far surpassing any normal treasure!

Just then, Yang Xie looked at the tai-black iron, only to see that half of it had a grayish complexion while the other half was still dark gold.

Yang Xie knew that since the auric essence had been drawn out, the half of the dark-grey tai-black iron had already turned into ordinary iron stones, and no longer had the ability to refine treasures. The other half could still be used with the smithing.

This half, Yang Xie naturally had to use to refine the original body of the Flying Sword.

Refining a sword embryo not only required a precious treasure like the tai-black iron, but also various other materials. Although Yang Xie was slightly familiar with the Path of Refining, he absolutely could not refine a sword embryo's body.

Fortunately, he had a treasure like the 'Stellar Pearl of Myriad Treasures'. Just as if this treasure could repair the Cold Sword, this Stellar Pearl of Myriad Treasures could also help him refine the sword embryo's body!

He already had the most precious tai-black iron s, and although the remaining materials were also extremely precious, they were still quite rare, but it was not impossible to buy them.

He used his wealth to clear the way, and in less than ten days, he had collected all the materials. His mind was immersed in the Stellar Pearl of Myriad Treasures, and he began to refine the sword embryo's body.

Yang Xie naturally had absolute confidence in this Stellar Pearl of Myriad Treasures. This treasure could even replicate that The Treasure of the Heavenly Passage, let alone a mere sword embryo's body.

Half a day later, Yang Xie opened his eyes and in front of him appeared a glowing gold longsword. The sword had not yet fused with the sword embryo, and the sword had no spirit, making it look dull and lifeless.

"The only thing left is to integrate the sword embryo into the Flying Sword."

Yang Xie's eyes flashed. Following the method of refining the Core Flying Sword, he opened his mouth and spat out the small golden sword above. The small golden sword landed on the Flying Sword and started to fuse together like water and milk.

This process was extremely slow, and it would take at least a few days before sword embryo could completely integrate into the rest of the Flying Sword.

Yang Xie sat motionlessly for the past few days. On the sixth day, the small golden sword had completely fused with the Flying Sword, and in the next moment, the Flying Sword erupted with dazzling light. The Flying Sword that lacked intelligence seemed to have come to life, and released a clear sword hum!

With a thought, the Flying Sword started to circle around him and dance in all directions. He even felt that with just a thought, the sword could cut through hundreds of miles in the sky and take the enemy's head away!

"This is the Flying Sword. With just a thought, it can slash in all directions, as if it was controlled by an arm!"

At this moment, the Flying Sword seemed to have become one of his arm. As his mind spun, the sword flew over, as if there was an invisible arm present!

Yang Xie's mind stirred, the Flying Sword stayed in front of his chest, it was a black gold longsword, the light flickering did not stop, although it was not activated, but as though there was a soaring sword qi pervading out from the Flying Sword, as though it was going to cut through the void!

Yang Xie flicked his finger, and a ding sound rang. Invisible sword aura burst out from the longsword, leaving many deep lines on the surrounding walls.

"This sword has been infused with the sword embryo that the senior has been raising for who knows how many years. Its power is far stronger than some treasures!"

Yang Xie revealed an excited expression. The might of the Flying Sword lay solely in the refinement materials and the strength of the sword embryo, the materials used to create this sword embryo were rarely seen in the world. Furthermore, the sword embryo had been refined by the Sage Stage powerhouses for dozens of years.

It was even a lot stronger than normal magic treasures!

"This time, it's all thanks to this' Stellar Pearl of Myriad Treasures'. Otherwise, if I wanted to refine this' sword embryo 'body, I would probably have to spend a lot of effort."

Yang Xie looked at the sword carefully, only to see the sword had a gold hue, and said: "Since this sword is refined by the tai-black iron, let's call it the taiwu sword."

Yang Xie gave the sword a name and with a thought, the taiwu sword turned into a ray of light and entered between his eyebrows, entering into his dantian.

Once a treasure of the first rank was absorbed into the user's body, they could activate their will and use it to kill the enemy!

His taiwu sword was originally a treasure of the first level, and since it was his Core Flying Sword, he could naturally withdraw it into his body and use it as he wished!

Yang Xie stood up, this time not only did he improve his own technique, his cultivation had also broken through to the Small Circle, his strength had increased by more than ten times!

At this moment, the spirit energy in his body was surging like a torrential river, and with a boom, the Dan Sea no longer appeared in his dantian, but instead, the Creature xuan tire!

The Xuan Yuan stood guard in the starry sky. There were a thousand stars, all condensed from various supernatural powers. All three of them were a single finger pointing to the heavens and a single finger pointing to the earth, as if they were suppressing all living things in the universe!

The Mysterious Creation Formula of the Universal Nature was like a big tree, and the Mysterious Creation Formula of the Universal Nature was the trunk. As long as the technique continued to grow stronger, more and more branches would be born, and at the same time, more and more branches would be born!

Just like the The Great Way of the Buddha, he had fused this technique into his own cultivation technique. This time, his physical body had become stronger, and if someone were to break open his bones, one could see that his bones were extremely tight, like steel, and their hardness was comparable to an ordinary spirit weapon!

Beneath his skin, there seemed to be boundless strength surging through his muscles. Once it erupted, it would shake the heavens and earth!

With this breakthrough, his spiritual consciousness could even be placed outside the range of five kilometers. It was as if all of the images within a radius of five kilometers were clearly imprinted in his mind.

In the area of his dantian, the lake that was originally a foot in size had grown to ten feet in size. It had expanded by more than ten times!
