At this moment, Yang Yunxiao stared at this strange knife without speaking, his eyes were completely focused on the blade, as if he wanted to see through this knife.

"If you don't try, how do you know if it works, and it's not a way to keep waiting." Old Man Yue said slowly, as if he was very confident that Yang Yunxiao could succeed, but there was a feeling of breaking the jar in his tone.

"If it really happens, this knife can not only cut off the reincarnation of your Yue family, but also do many other things." Yang Yunxiao glanced at Old Man Yue, and couldn't help but raise the corners of his mouth, but then returned to a serious demeanor.

"That's natural, now it's up to you to see if you can take this step, if this hurdle is overcome, the back will not be so desperate." Old Man Yue's tone was slow, full of charm and long.

At this moment, Yang Yunxiao didn't speak, he looked at the knife quietly, and one ancient smelting technique after another appeared in his mind, all of which were some secret methods in ancient times, the ancestors of the Tian clan had learned these secret methods, and later passed down many classics, among these classics, all the secret techniques of that era were recorded, and they were widely spread among the Tian clan.

However, with the passage of time, these classics have gradually been lost, and now only a few fragments are stored in the library of the Heavenly Emperor City.

Not only that, these volumes of classical texts are all some secret sayings and ancient sayings from ancient times, which even contain the shackles of the Heavenly Dao, looking at the entire Tian clan, only Emperor Qingcang and his junior brother Emperor Qingtian have the strength to penetrate a few words.

And now, Yang Yunxiao comprehends these secret methods through the memory of Emperor Qingcang, which is undoubtedly an extremely difficult thing, after all, these classical words contain the shackles of the Heavenly Dao, and it is difficult to successfully comprehend them.

Under such circumstances, Yang Yunxiao fell into a state of meditation and enlightenment, time passed minute by minute, and unconsciously, Yang Yunxiao's expression was distorted, and he was sweating profusely, and sweat the size of pearls continued to drip from his face, as if Yang Yunxiao was engaged in a battle between heaven and man at this time.

At this time, Shentu Liming couldn't help but look at Yang Yunxiao solemnly, he even suspected that Yang Yunxiao would be very likely to die of exhaustion if he continued like this, he just wanted to stop it, but when he saw the ghost-like gaze of the old man Yue, he had to give up this idea.

It didn't take long for Yang Yunxiao to be soaked with sweat all over his body, and the whole person seemed to have just been fished up from the river, at this moment, Yang Yunxiao was wearing a big gulp, out of breath, that feeling was like a drowning person, at the moment of death, he breathed fresh air again, it seemed that he didn't come up in one breath, and it was easy to suffocate on the spot.

At this moment, not only Shentu Liming, but even Old Man Yue began to worry, they were all afraid that Yang Yunxiao would go mad and fall into madness.

At this moment, in Yang Yunxiao's mind, countless words emerged, one after another mysterious rune inscriptions were constantly beating, all exuding a terrifying heavenly dao aura, in the dark, this heavenly dao power was like a huge copper wall and iron wall, frantically preventing Yang Yunxiao from penetrating the shackles of the heavenly dao.

Back then, in order to seek a complete secret method classical, Emperor Qingcang had more than once explored the heavens through the innate quenching anti-heaven divine technique, although he could successfully avoid the detection of heaven's will every time, but such an act undoubtedly greatly improved the vigilance of heaven's will.

Until the end, Emperor Qingcang was unable to deduce the complete outline of the Heavenly Dao, and those secret classics hidden in the Heavenly Dao still could not be fully presented to the world.

"-" After half a day, Yang Yunxiao suddenly scolded, and the whole person was so tired that he collapsed directly to the ground, almost fainting.

"Hey! Are you okay! Seeing this, Shentu Liming was shocked, and hurriedly went up to help Yang Yunxiao up, he never expected that in order to seek the secret method that had been lost a long time ago, Yang Yunxiao almost lost half his life!

Yang Yunxiao was overwhelmed, took out a precious pill from the Sumeru bag, and threw it directly into his mouth, only then did he regain his strength.

Yang Yunxiao let out a long breath and rested for a long time before he slowly stood up and tried to adjust his state.

The feeling just now, like dying and suffocating, that dying feeling, even made Yang Yunxiao feel terrified, this is a hundred times more terrifying than climbing the 999th floor of the Xuantian Ladder!

After relieving himself, Yang Yunxiao looked at the old man Yue and said: "I found a few ancient methods, you can try them, but it's just to add something to the fire, as for the knife, you still have to rely on yourself, I can only guarantee that there will be no accidents at this step now." ”

Hearing this, Old Man Yue nodded and said, "Of course, that's enough." ”

After a brief rest, Yang Yunxiao returned to his peak state, he glanced at Old Man Yue, and couldn't help but say: "This is the case, but it is far from enough to exchange the Immortal Dao Qin and the Immortal Tree. ”

"Immortal tree, I will give it to you for free, you can mention the conditions as you like, and you can choose the treasures here, as long as I can do it." The old man did not hesitate, very generous.

As soon as Old Man Yue said this, Shen Tu Liming on the side showed a look of surprise, he couldn't imagine what the origin of this knife was, so that Old Man Yue would exchange benefits from Yang Yunxiao at all costs.

On this vast meadow, any thing taken out is enough to cause a sensation in the entire human mortal world, and each of them is a peerless treasure that the emperor covets.

It's just that for such conditions, Yang Yunxiao just smiled and didn't care.

"You know, I don't lack treasures, although the things you have here are extraordinary, but they are not enough to make my heart flutter, I only want one thing, which is this knife." Yang Yunxiao said lightly.

As soon as these words came out, Shentu Liming suddenly felt very pity, so many rare treasures Yang Yunxiao didn't want, which was equivalent to missing an opportunity to soar in vain, if it was Shentu Liming, he would definitely choose to take a few treasures here.

But after thinking about it, although this knife doesn't look special, it will definitely be a shocking treasure if it can make Old Man Yue value it so much, and it is not unreasonable for Yang Yunxiao to want this knife.

It can be seen from here that Yang Yunxiao is very far-sighted.

It's just that Yang Yunxiao wants it, and Old Man Yue may not give it, after all, Old Man Yue regards it as everything, this is a magic knife that can determine the fate of their Yue family.

At this time, Old Man Yue didn't speak, his brows were furrowed, as if he had been hesitating in his heart, not knowing how to choose.

Seeing that the old man of the moon hesitated, Yang Yunxiao couldn't help but say: "In this life, no one from your Yue family will reach the top, you know this better than anyone else, and I want this knife, it is also after your Yue family cuts off the reincarnation, at that time, even if this knife is left in your hands, it is just a tyrannical thing, of course, I only need to use this knife before reaching the top, and after reaching the top, I will naturally return it to you." ”

Hearing this, Old Man Yue still hesitated for a long time, he looked at Yang Yunxiao, and seemed to see an extraordinary aura from his body, and finally, Old Man Yue relented:

"Okay, as long as you can succeed, do as you say."

Hearing this, Yang Yunxiao couldn't help but smile slightly, in his opinion, Old Man Yue had made a very correct choice.

"The Five Elements Qiankun Ding, the red sandalwood golden flame wood, the thunder flower, the sophora sophora royal jelly, the essence blood of the black phoenix feather dragon, start the furnace, open the ding!" At this time, Yang Yunxiao stared at the knife in front of him and said seriously.

As soon as the words fell, the old man Yue waved his hand, and a finely carved furnace ding instantly appeared in sight.

This furnace is more than one zhang long, with water gold color ink depicting the dragon and painting the phoenix, the four tripods are engraved with the general history of the past dynasties, plus the real iron pure copper to refine the fire, with copper as the body, with iron shape. The shape of the vessel is huge, and the lid is attached, its mouth is slightly constricted, folded along, the abdomen is deeper, the bottom is round, the two sides of the tripod abdomen are attached to the ears, the four hooves are placed below, and the foot root is decorated with a relief animal face.

Seeing this furnace tripod appear, Shentu Liming's heart was shocked, and he could clearly feel that this furnace tripod in front of him was definitely stronger than the emperor furnace in the world!

In the next second, all kinds of materials reported by Yang Yunxiao before also flew out of the air one by one, under the manipulation of the old man Yue, the red sandalwood flame wood instantly ignited, heating the furnace ding, and the five elements Qiankun Ding quickly heated up, and a large number of unheard of and unseen treasures were all thrown into the furnace, making a crackling explosion.

"Doom demon scorpion, take the shell, grind the powder, fuse with the birth water, and enter the furnace! Be quick! Yang Yunxiao roared.

At this moment, Old Man Yue's big hand swept out an afterimage in the air, and instantly grabbed a giant scorpion full of evil aura in a black jar, as soon as this scorpion appeared, Shentu Liming was startled on the spot!

Devil Scorpion! This is a third-rank Chaos Beast! Yin is extremely vicious and powerful, even if some powerhouses in the half-emperor realm meet them, they must retreat and dare not shake them.

However, Old Man Yue grabbed it out with one hand without any scruples, easily pinched it to death with only two fingers, directly lifted its shell, ground the powder, fused it with the birth water, and immediately put it into the furnace.

"Wow-" At this moment, for some reason, a shout suddenly came from the furnace, very similar to the cry of a human, but there was no movement in an instant.

"Okay, I'll take care of the rest!" Yang Yunxiao saw that the old man had laid all the foundations, and couldn't help but shout and quickly took action.

At this moment, Yang Yunxiao's shot was as fast as lightning, and he instantly summoned the supreme divine fire unique to the innate quenching - the Black Flame of Annihilation!

In an instant, a black flame that was enough to destroy the world surged out, instantly devouring the entire furnace ding, enveloping all the furnace dings, only to see Yang Yunxiao palm the furnace ding, fire control temperature control, completely ignoring the crackling sound coming from the furnace ding, but the fine beads of sweat on his forehead proved that the difficulty of controlling the furnace ding was definitely beyond the imagination of the world.

In the next second, as the black flame of destruction in Yang Yunxiao's hand increased its power, the fire in the furnace was instantly surging into the sky, and the flames were shining for thousands of miles, as if it could burn through the entire sky, and the sound of burning fire vibrated the eardrum, and the scorching and terrifying temperature actually burned the surrounding air to a dense and distorted body, which made people frightened and retreated.

At this time, even a great power like Old Man Yue subconsciously retreated again and again, completely shocked by such a terrifying might.

Yang Yunxiao didn't know what kind of secret method he used, and he controlled the furnace in a very fast way, and a series of actions such as converter, locking ding, condensing gas, and melting device were carried out almost simultaneously, and countless forces alternated from the inside to the outside and from the outside to the inside, which was intricate, dazzling, and it was impossible to see where it was.

With such a complex and mysterious technique, even if an emperor came to observe, it was impossible to see the slightest mystery in it.

After all, the secret method used by Yang Yunxiao contained the shackles of the Heavenly Dao, and if it wasn't for someone who had reached the pinnacle, he would definitely not be able to understand half of the mystery.
