The words of Su Ao, the Lord of the Heavenly Punishment Domain, made everyone present feel amused.Chu Batian hurriedly diverted the topic and said, "Okay, let's talk about this matter later, the top priority is to discuss how to deal with those people in the Eighteen Regions." Also, Yun Luotian must not be dead, we need to do our best to catch that kid and get his whereabouts from his mouth!"

Chu Batian's words made the other eight people fall silent, and after a long time, the gray-haired old man said: "For today's plan, we must first deal with this big war." As for that kid, we might as well send an order down first, let the people left behind explore, the Heavenly Punishment Domain is so big, I don't believe he can hide in the ground forever and never show his face!"

"That's it!" Chu Batian frowned and thought for a moment, and couldn't think of any way to force Zhang Hao out of the ground. The battle with the Eighteen Regions will take place in two days, so you can only deal with this battle!

Seeing that he agreed, the others didn't say anything more, and got up one after another to say goodbye and leave.

Su Ao, the Lord of the Heavenly Punishment Domain, did not forget to snort when he left, and said, "Chen Yeyu, I will definitely find out about this matter, if those subordinates of the Heavenly Punishment Domain were sent to the Riot Star Domain by your behemoth......"

Although his later words are not spoken, the meaning of the threat is clear.

Seeing this, Chen Yeyu, the lord of the Tianqi Domain, had a slightly gloomy face, sneered, and said, "Waiting for you at any time!"

The others were helpless about this, the Heavenly Punishment Domain Lord Su Ao had never taken them seriously, he would say anything to his face, and he would never take into account the feelings of others, which they had long been used to, so no one took it to heart.

Chu Batian watched everyone walk out of this gray space, frowned slightly, and said, "I'm afraid this matter has something to do with him, otherwise, Su Ao wouldn't have mentioned this matter on the occasion of the Great War!"

"He's reminding us!" Heavenly Punishment Domain Lord Cao Yanfei smiled, then stood up and said, "This battle must severely damage the Eighteen Regions, otherwise we will never have time to search for the heir of the Cloud Falling Sky!"

Hearing this, Chu Batian nodded, and immediately hugged his fists and left. In the gray space, only Cao Yanfei was left, and he stood in the pavilion for a moment before leaving!

In the Hongmeng Fire Tower, Zhang Hao walked out of the multi-heavy fire on the fifth floor, raised his hand to put on the clothes that were thrown on the ground, and said, "Master, there is something I want to discuss with you!"

The voice of the clouds falling from the void echoed within the fifth layer: "No need, you can make up your own mind if there is anything!"

Hearing this, Zhang Hao nodded silently, then sat near the exit of the fifth floor, and said, "This knife is not enough to deal with the danger now, I want to borrow something from you!"

"But you want to refine it again?" After a while, Yun Luotian suddenly appeared in front of him and smiled: "Also, this knife was originally used by the old man when he cultivated the truth, and it is indeed not suitable for dealing with those immortal cultivators!"

As if he hadn't heard, Zhang Hao sat there frowning and pondering, and then exhaled for a long time: "It has accompanied me all the way through life and death, but now it has to ......."

He didn't say the following words, but Yun Luotian understood, smiled and picked up the black war knife from his side, and said: "The old man's relationship with it is no worse than yours, although it is just a blade, but it is like a friend in the heart of the teacher!"

"Buzz!"

The black blade suddenly trembled, and a black dragon phantom several meters long slowly condensed and formed around Yun Luotian, and then coiled around him, and the dragon head rubbed the old man's arm affectionately, letting out a low roar!

Since getting this knife, it was the first time that Zhang Hao saw the beast spirit hidden in the blade, and a trace of surprise couldn't help but appear on his face.

In the past, he used soul detection more than once, but he couldn't detect that there was a beast spirit in the blade, but now this knife is in the hands of Yun Luotian, but it has appeared!

"Hehe, it is a beast spirit that was encountered when the teacher entered and exited the Nine Heavens and Eighteen Domains, it was still extremely weak back then, and it could dissipate with heaven and earth at any time, and in desperation, the old man had to seal it in the knife!"

Yun Luotian smiled and patted the head of the black dragon beast spirit, and said, "This is also the reason why it never appears, now that you want to refine this knife, let it accompany the old man for a period of time, and after the knife is refined, it will go back!"

"Isn't there a way to restore the remnant soul?" Zhang Hao stared at the clouds falling into the sky, asking a question that had been hidden in his heart.

Ling'er is a remnant soul, and so is the old man in front of him, even this black dragon!

"This ...... Maybe there is a way, but now yours can't do it!" Yun Luotian hesitated for a moment, and sighed with a smile: "Old man, it is extremely difficult to recover this remnant soul, but it is different, as long as there are enough beast spirits to devour it, plus the Hades Emperor Shan and the Nine Shadows Heart Fire that were given to you some time ago, it should be able to restore it!"

"Nine Shadows of the Heart...... Immortal Shan ...... Enough beast spirits!" Zhang Hao muttered softly, and then fell silent. What Yun Luotian said must have reached a very large level.

But now that he has not even a beast spirit left in his hand, where can he look for it?

After a while, Zhang Hao had no choice but to suppress the thoughts in his heart and take out the Qiankun furnace: "I need something hard to improve this knife, and ...... To increase its weight!"

"Xuanxin Iron, Tianxin Stone!" Hearing this, Yun Luotian smiled and announced the names of the two things, and with a stroke of his palm in front of him, the black crack slowly appeared.

Reaching into it and grabbing out more than a dozen black stones, as well as some fine white powder, and putting these things on the ground, Yun Luotian smiled and said: "These things should be enough, as for the formation in it, you can do it yourself!"

Seeing this, Zhang Hao nodded, and fell silent again!

A transparent ball quietly appeared in his hand, and the inheritance bead left by Venerable Xingyu recorded a huge array and refining technique, and if you want to learn all of them, I am afraid that it will not be possible for hundreds of years!

Fortunately, Zhang Hao was in the Hongmeng Fire Tower, and he had enough time to study these esoteric formations, and the time was slowly draining away day by day, but his brows were kept locked.

The alchemy recorded in the inheritance bead, the first half of the volume is the blade under the refining of heavenly weapons, while the second half of the volume records the art of refining immortal weapons. In the last paragraph, Zhang Hao only read it once, but he felt confused and had to put all his mind on the novella!

In this refining chapter left by Venerable Xingyu, the things needed to refine the immortal weapons are described in great detail, including the Xuanxin Iron and Tianxin Stone taken out by Yun Luotian.

These two things, in the Nine Heavens and Eighteen Domains, are extremely rare things, Xuanxin Iron is a kind of refining thing that is a special product of the Heavy Martian Domain, the size of a fist, it weighs thousands of catties, and the texture is extremely hard.

In the records of Venerable Xingyu, it was described that even Heavenly Fire could not refine it.

The Tianxin Stone is a special product of the Tianyan Domain, and after refining, it can be integrated into the blade to prevent the weapon from being too hard and shattering itself.

With these two things, Zhang Hao put his mind at ease and continued to study for a long time before putting away the inheritance bead, and with a wave of his palm on the Qiankun furnace, a fierce blue and white flame emerged in it!

The domineering and peculiar temperature of the Yin and Yang Fire was actually not suitable for refining weapons, but this time, Zhang Hao just needed that kind of flame that alternated between extreme cold and heat.

The blue and white flames of yin and yang rose endlessly in the furnace, and he did not rush to throw the black war knife into it, his palm pressed against the blade, gently slashing over its surface.

The power of the soul invaded the inside at the same time, carefully probing the formation contained in the blade, going back and forth a dozen times before he was sure that he could understand, and then put the knife into the Qiankun furnace!

The blue and white yin and yang fire immediately rolled the knife into the flame, and the strange temperature alternated, and with Zhang Hao's continuous urging, after a few hours, it suddenly shattered!

Hundreds of splinters floated in the flames, slowly melting until two days later, when they turned into a mass of black solution.

During this time, Zhang Hao has not dared to be careless, but at this moment, when he finally melted it, he breathed a sigh of relief in his heart, and then put the Xuanxin Iron into the furnace!

The Xuanxin Iron, which was in the shape of a black block, was swept up in blue and white flames, and there was no movement for a long time. However, Zhang Hao was not anxious, and carefully paid attention to the changes in the flame in the furnace!

It took a full ten days for the surface of Xuanxin Iron to gradually squirm, and this sign of imminent melting made his tired mind feel a little uplifted, and he hurriedly pushed the Yin and Yang Fire to the limit.

In the space above the furnace mouth, under the swirling of this flame, a black hole suddenly appeared!

"Condensation!"

At this moment, Yun Luotian quietly arrived, and with a palm of his hand against the black hollow, he imprisoned it, and the ability to change the space at will made the corners of Zhang Hao's eyes jump.

I wanted to ask for advice, but now was not the time, Zhang Hao had no choice but to restrain his mind and continue to control the flames in this furnace!

From the beginning of the Dacheng stage, a cultivator can absorb a trace of spatial energy in his body, so as to use this energy to fuse with the surrounding space to achieve simple control.

Immortal cultivators, however, have improved their ability to comprehend space a lot, and they can use the immortal power in their bodies to forcibly break through the space and shuttle through it at will.

And the cloud falling into the sky that is just a remnant soul, showing the ability to grasp everything, but it is far beyond Zhang Hao's cognition!

In the Qiankun furnace, the surface of Xuanxin iron began to melt, and drops of pure black solution floated in the flames.

At first, as the temperature of the fire of yin and yang changes, condensation will also occur, but when the number of alternating between extreme cold and extreme heat increases, it becomes stable!

It wasn't until all the Xuanxin Iron had melted into a black liquid that Zhang Hao put the white powder of the Tianxin Stone into the furnace, and under the refining of the blue and white flames, it was quickly melted completely, which was a bit beyond his expectations!

The majestic soul power poured into the furnace, and began to stretch the three liquids fused together, and as the blue and white flames surged, gradually, a black war knife reappeared in the furnace.

After waiting until it was exactly the same as before, Zhang Hao used the power of his soul and began to carve the formation inside the blade.

At the same time, the Nine Shadows Heart Fire replaced the Yin and Yang Fire and began to refine this nascent battle knife.

Half a month later, Zhang Hao activated the Immortal Starfire again and replaced the Nine Shadows Heart Fire, and at this time, his face became extremely pale!

Under the spark quenching, there were constantly starlight seeping into the inside of the blade, and at the same time, Zhang Hao's hands also formed a complicated imprint, and the majestic soul energy gradually formed a black hole the size of a thumb around his fingers.

The soul energy floating nearby was suddenly devoured by this tiny void.

But Zhang Hao suddenly snorted softly, and flicked the void that was constantly devouring soul energy into the Qiankun furnace, and slowly merged into the knife with the swirling sparks!

Somewhere in the upper layer of the Hongmeng Fire Tower, the purple-haired old man frowned and said, "What does this kid want to do by punching the Soul Devouring Mark into the blade?"

In this regard, Yun Luotian smiled, smacked his lips and said: "The bastard boy is full of bad intentions, he must not be well-intentioned, it seems that someone is going to be unlucky!"

But the purple-haired old man glanced at him with strange eyes, and sneered: "What kind of master is there, what kind of apprentice is there, look at your current face, the old man is embarrassed to sit with you!"

"Old thing, don't look for trouble!" Yun Luotian withdrew his gaze from the light curtain and snorted: "If you want to fight, just say it, the old man will accompany you!"

Seeing this, the purple-haired old man was also angry, suddenly got up, and shouted: "Fight, fight, the old man was not afraid of you thousands of years ago, and it will be the same thousands of years later!"

And Yun Luotian smiled angrily: "It's okay, today the old man will teach you the underworld**!"

The two then engaged in an earth-shattering battle......
