Wan Dong didn't know what Mu Tiannan was thinking at this time, his whole body and mind had already entered the realm of selflessness. The sword-casting technique of the Xuantian Great Ming God, Wan Dong used the attainments of the Shinto Realm to display it, and he felt that the mystery was endless, and at the same time, he was more freewheeling.

Wan Dong likes this state, as if he is the creator, controlling a qiē! This feeling was also felt when Wan Dong first forged swordsmanship, but it was far less intense than it is now. Especially looking at the indestructible Sun Stone, when it melted little by little in the scorching fire of Dao Qi, it made Wan Dong's heart swell with an inexplicable excitement.

In such a realm, time seems to have ceased to exist, and in the blink of an eye, it has been a day and a night! Mu Tiannan stared at the side for a day and a night without blinking, and he didn't feel the slightest boring and tasteless.

At first, Mu Tiannan only felt the fire of Dao Qi condensed by Wan Dong, which was extremely hot and extremely high, but then slowly, Mu Tiannan actually felt the power of the slightest law from it. This shocked Mu Tiannan at the same time, but also seriously studied Wan Dong's sword-casting technique, and in the end, he was a little addicted.

After a day and a night of smelting, the Sunstone finally turned into a brilliant liquid. The beautiful luster and moving form all made Mu Tiannan's heart shake. Before Mu Tiannan could observe carefully, a strange purple flame burst up from the molten liquid of the scorching stone, accompanied by a crackling and crisp sound. Mu Tiannan knew that this was Wan Dong's further removal of impurities from the Sun Stone.

It's just that with Mu Tiannan's experience, this step should be carried out in the sword casting furnace. With the fire of Dao Qi and the various Xuanhuo created by nature and earth, supplemented by the spirituality of the sword-casting furnace itself, it can often save nearly half of the swordsmith's strength. But Wan Dong is good, the Heaven and Earth Xuanhuo and the Sword Casting Furnace are not used at all, only the fire of Dao Qi, and there is no pause in the middle, all in one go, which really makes Mu Tiannan a little worried.

Once Wandong consumes too much and does not have the strength to continue, it will not be a great threat to Wandong himself. But after looking at it for a while, Mu Tiannan completely relieved his heart, Wan Dong's expression was relaxed, as usual, not even a drop of sweat appeared on his forehead, where was there any sign of unstoppable?

Although Mu Tiannan was relaxed, at the same time, he became more and more curious about the sword-forging technique that Wan Dong had performed. And the excitement and hope contained in the eyes, out of nowhere, became more and more intense!

Removing impurities from the material of a forged sword is by no means easier than melting it. In particular, the impurities stored in the sun stone are not comparable to ordinary impurities. Wan Dong's smelting took another day and a night!

After two days and two nights of fighting, Wan Dong's eyebrows finally revealed a touch of exhaustion.

To be honest, such a troublesome task really exceeded Wan Dong's expectations. Even if the texture of the Burning Sun Stone is extremely hard, it will not take two days and two nights to cultivate at the beginning of Wandong's current Divine Dao Realm. What's more, even after two days and two nights, the Burning Sun Stone still did not reach the pure Cheng dù that Wan Dong wanted, and there was still a piece of walnut-shaped black impurity in it, no matter how Wan Dong drove the Dao Qi Fire, it could never be refined.

What surprised Wan Dong even more was that as the Dao Qi Fire continued to activate, the walnut-shaped black impurities actually began to erupt one after another, although it was not very strong, but it was an extremely obvious black light under the cover of the Dao Qi Fire. This light was filled with a lot of force, constantly resisting, and even driving away the fire of Dao Qi that was close to it.

"What's going on?" Wan Dong couldn't help but feel puzzled. He had never been in such a situation before.

"Yaoting, stop it!" Just when Wan Dong was puzzled, Mu Tiannan suddenly shouted, and his voice was clearly full of shock.

Wan Dong looked up at him in confusion, only to see Mu Tiannan's eyes, as if he had been struck by an evil spirit, staring at the walnut-shaped black impurities, refusing to move them for a moment.

"Mu Lao, what the hell is this? The fire of my Dao Qi is unexpectedly refined. Wan Dong knew that Mu Tiannan must have seen the origin of this black impurity, and hurriedly asked.

Mu Tiannan's white hair was trembling with excitement at this time, and he said, "Yaoting, this is ...... I'm afraid this is a sword soul! ”

"Sword Soul?" Wan Dong is not very unfamiliar with this point, and it has been mentioned in the sword-casting technique of the Xuantian Great Ming God.

But whatever can be called a divine soldier is made of the finest metal that was born and bred by nature. Such a metal is no longer comparable to ordinary metals, and it has a certain spirituality in itself. It's just that this kind of spirituality, no compared to the spiritual intelligence of humans and immortal beasts, is in a state of chaos and disorder most of the time. But this state is by no means fixed, in both cases, there will be a very low probability that this chaotic and disorderly spirituality will be set right and condensed into a sword soul.

One case, in the process of casting! It depends on the skill of the swordsmith and how much effort is put into the casting process. And whether the cast divine soldier has spirituality, or how much spirituality it has, is often the first criterion for judging a swordsmith's sword-casting attainments!

Another situation is that after the casting is completed, the divine weapon meets certain circumstances and conditions in the process of use, and there is also a considerable chance that the sword soul can be generated. For example, as everyone knows, if a divine soldier kills too much, it will often become extremely sharp and murderous, which is where the divine soldier generates a sword soul after eating human blood!

It's just that the probability of these two situations is very low, even in the Daomen Great World, there are very few divine weapons that can generate sword souls. However, once the sword soul is generated, the quality of the divine weapon will immediately undergo earth-shaking changes. On the weapon spectrum of the Daomen Great World, it seems that there is no divine weapon with a sword soul in it!

In the memory of the Xuantian Great Mingshen, before the Xuantian Great Ming God ascended into the Immortal Court, he had never cast a divine weapon pregnant with a sword soul, compared to the Xuantian Great Mingshen, Wan Dong's sword-casting technique was at most a half-ass, to say that he could cast a divine soldier pregnant with a sword soul, I am afraid that even he did not believe it. What's more, Wan Dong has only only reached the stage of molten refining, and he is still early to forge a divine weapon, even if he can generate a sword soul, it should never be at this time.

"Could it be that the Sun Stone itself contains a sword soul?" Wan Dong's heart moved, and Huo looked at Mu Tiannan. Mu Tiannan nodded heavily at him, obviously the two of them wanted to go together.

"My big brother Xiao's luck is too good, isn't it?" Wan Dong couldn't help but raise his eyebrows and laugh.

"Don't be happy first, in my opinion, this sword soul is just a remnant soul, not completely, if you don't get it right, it will be wiped out, then you want to cry without tears!" Mu Tiannan's words immediately made Wan Dong's expression solemn.

The Burning Sun Stone that Xiao Lang found should be a fragment of some kind of divine weapon shattered, so it contained a part of the Broken Sword Soul. If you are not careful, it will really be as Mu Tiannan said, the remnant soul will dissipate, and there will be empty joy!

Wan Dong originally wanted to use the fire of Dao Qi to refine it, but at this time, he didn't dare anymore. Not only did he not dare, but he also hurriedly released a piece of qi, carefully wrapped it, and protected it closely!

Originally, the sword forging process was not very fast, because the discovery of the sword soul slowed down even more.

One day, two days, three days...... In the blink of an eye, another three days passed.

In the five days before and after, Xiao Lang didn't know how many times he wandered outside the sword-forging room. Ling Tianhou and Ling Feiqiu were like two generals, guarding the door of the sword-casting room, making Xiao Lang scratch his ears and cheeks in a hurry, but he couldn't help it.

"Did you come out?" Before Xiao Lang's figure could be seen, his voice came first.

Ling Tianhou and Ling Feiqiu glanced at each other and shook their heads with a wry smile. Every time Xiao Lang appears now, it means torture to them. If there is also a realm of stalking and soft grinding and hard bubbles, then Xiao Lang is definitely in the Holy Soul Realm!

"Didn't he take the Nakshatra Pill, why did he come again so soon?" Ling Feiqiu asked strangely.

Without waiting for Ling Tianhou to answer, Xiao Lang had already flown like a rabbit. After a few days of recuperation, Xiao Lang's injuries have healed. Not only that, Xiao Lang also took the opportunity to take the Star Pill, and at this time he had completed his rebirth, and he was even more heroic than before!

Unlike Luo Xiao and them, after Xiao Lang took the Xingzhu Pill, he no longer deliberately suppressed his cultivation, but with the help of the reborn medicinal power of the Xingzhu Pill, he broke through the bottleneck one after another, and his cultivation was directly promoted from the beginning of Tiange to the peak of Tiange!

At this time, if he is against Jiuwu Chong again, even if he is unarmed, Xiao Lang can beat him and can't take care of himself!

Xiao Lang's tremendous changes, Ling Tianhou and Ling Feiqiu obviously saw it in their eyes, although they were amazed, but they were not very surprised. With Wan Dong and Wang Yangde in front, it is estimated that in this world, there is nothing that can surprise them.

"Good boy, I haven't seen you for a day, and I've improved so much, amazing!"

Ling Tianhou gave Xiao Lang a thumbs up and said.

Xiao Lang waved his hand, without even saying a word of politeness, and asked: "It's been five days, why haven't Yaoting and Mu Lao come out yet?" ”

To be honest, it wasn't much a few days ago, but on the fifth day, Ling Tianhou and Ling Feiqiu were starting to worry a little. This sword casting is the same as alchemy, it is also risky, a bad trouble, the sword is not cast, but the person is gone, it is not that it has not happened.

"Don't get in your way, quick, let me in!"

Seeing Ling Tianhou and Ling Feiqiu looking like this, Xiao Lang, who was already anxious, couldn't hold it back, and he raised his leg to break into the sword casting room.

Ling Feiqiu hurriedly stopped him and said, "You kid is crazy!" Have you forgotten what Mu Lao said? Piss him off and watch out for your ass! ”

"But......" Xiao Lang wanted to say something, but he was afraid of Mu Tiannan's majesty, and his mouth opened and closed several times.

"Third child, to be honest, I'm a little worried! Although the Sun Stone is difficult to do, it doesn't take five days, will there be an accident inside? What Xiao Lang didn't say, he let Ling Tianhou say it.
