"This Hundred Flame Essence is in your hands for the time being. The tassel under the spirit body of the sacrificial vessel swung down, and the purple fire floating above the Song Ding floated towards Su Yu.

The spirit of the sacrificial vessel shot a purple light towards Su Yu, and the purple light quickly burrowed into Su Yu's body and disappeared, and the next moment, Su Yu clearly felt that there was a trace of connection between himself and the purple fire.

As soon as Su Yu's mind moved, the purple fire flew forward, and Su Yu waved again, and the purple fire floated towards him.

This feeling is very strange, just starting to control the flame, Su Yu is still a little jerky, but there is no doubt that Su Yu is excited in his heart, when will he be able to have a flame of his own?

But Su Yu soon found that the spiritual power in his body was flowing rapidly, and it was too much spiritual power needed to control the Hundred Fire Essence!

It's just that he controlled the Hundred Fire Essence to float twice, and the spiritual power in Su Yu's body had already consumed nearly one-fifth!

At that rate, it's not just seven days!

I'm afraid he won't be able to hold it for even three days, and he also has to count the three Qi Returning Pills given to him by the Burning Vessel Spirit!

Realizing this, Su Yu's face became solemn, he had to persist for seven days, and the spiritual power could not be disconnected in the slightest during the process of washing and casting, and those three Qi Returning Pills must not be used until the final moment of exhaustion!

"The spiritual power in the body of the Hundred Fire Essence will indeed be a little too consumed for the first time, but it will be better after becoming proficient. The Sacrificial Vessel Spirit seemed to see the worry in Su Yu's heart and spoke.

"Hmm. Su Yu nodded, and once again controlled the purple fire to familiarize himself, this circle, the consumption of spiritual power is indeed much smaller.

While controlling the flames, Su Yu ran the basic exercises to restore his spiritual power, although the spiritual power consumed was inversely proportional to the spiritual power recovered, but there were still three Qi Returning Pills, Su Yu estimated that it should not be a problem to persist for seven days.

"Once you have control over it, let's refine the alchemy rope first!" The machine spirit looked at Su Yu, who was already able to control the essence of the hundred fires, and threw the blue-white light cluster with the alchemy rope around the song ding into the song ding.

Su Yu controlled the Hundred Fire Essence to move towards Songding, the purple flames were burning, he knew that once he started refining the alchemy rope, he would have to hold on for seven days without stopping, and it might take longer!

"Hoo ......"

Su Yu exhaled again, and when it was really time to start, he was a little nervous.

"Hundred Fire Essence, out!"

Su Yu knocked out the essence of the hundred fires and fell under the Songding, the moment the purple flame touched the Songding, the fire suddenly rose, and a flame only the size of a palm rose in an instant, spreading over the Songding and devouring the Songding!

Such a sudden change startled Su Yu unexpectedly, and the spiritual power in his body also flowed wildly at the moment when the flames surged.

But he quickly calmed down, and the purple fire skyrocketed for only a moment, and then it stabilized, and the spiritual power flowing in his body also stabilized.

The essence of the hundred fires rose under the Songding, and the purple flames enveloped the entire Great Ding, and under the burning of the flames, the Songding gradually changed......

The blue-green Song Ding began to slowly turn red, and the flowers, birds, insects and fish carved on the body of the Ding seemed to be alive, swimming in the body of the Ding, adding a lot of vitality to the Song Ding.

The inside of the ding was red, and the blue-white light of the alchemy rope in the ding faded, revealing the stone lock shape when the alchemy rope was contracted, without the slightest movement.

Su Yu understood that the alchemy rope would not reveal its original rope appearance until it was refined, and Su Yu wanted to know what kind of rope the alchemy rope would be after it was refined.

Song Ding has been burned red, but the stone lock has not changed in the slightest, not even the color has changed at all!

Su Yu patiently continued to refine, did not increase the output of spiritual power, nor did he raise the temperature of the Hundred Fire Essence, the alchemy rope is a rare treasure in the world, even the Hundred Fire Essence may not be able to refine it in an instant, so the stone lock did not change It was also expected by Su Yu.

Not only the alchemy rope, but also the Creation Immortal Dew and Divine Iron will not change because of the flames.

But except for the Hundred Fire Essence and the legendary Samadhi True Fire, these materials can never be refined with ordinary flames, and the Hundred Fire Essence is already the essence of the strange fire, and its temperature is high enough to incinerate together, even so, it will take a lot of time to refine the alchemy rope, let alone burn it with ordinary flames, I am afraid that there will be no change if it is burned for a year.

Su Yu probably had the bottom in his heart, it would take at least seven days to wash and cast the Traceless Sword, but the time to refine these materials would probably not be less than three days, and the alchemy rope passed without the slightest movement under the incineration of the Hundred Fire Essence.

"Keep the current temperature and continue refining, and when the shape of the stone lock of the alchemy rope changes, revealing the appearance of the rope, throw the traceless sword into the songding, and under the burning of the essence of the hundred fires, the alchemy rope will naturally be wrapped around the traceless sword. "The spirit of the sacrificial vessel spoke, now it is just the beginning, everything is not difficult, but with the addition of the same material, Su Yu will have to spend more and more energy, and the spiritual power consumed will become stronger and stronger.

"Hmm. Su Yu responded, his eyes staring at the alchemy rope in the Song Ding, not knowing when he would be able to refine the stone lock.

Su Yu maintained a uniform output of spiritual power in his body, and at the same time operated the basic exercises to restore the consumed spiritual power, and all the spiritual energy around him converged towards Su Yu's body.

Absorbing spiritual energy while consuming spiritual power to restore one's spiritual power was a big technical task for Su Yu, at least before, Su Yu had never tried such an act.

At first, when Su Yu was running the basic exercises to absorb spiritual energy, he almost blocked the output of spiritual power, after all, restoring spiritual power and outputting spiritual power are two completely different concepts, fortunately, Su Yu stopped in time, and the refining alchemy rope was still in the initial stage, otherwise this moment just now would be enough to declare the failure of washing and casting.

"It's dangerous!"

Su Yu's chest fluctuated, and he shouted in his heart to be glad, fortunately, he did not have high requirements for the control of the Hundred Fire Essence now, and he stopped it in time, so that he was not affected by the alchemy rope in Songding.

But Su Yu understands that he can't just give up, he must take advantage of the fact that he is still relatively easy to combine the absorption of spiritual energy and the output of spiritual power, so that when he outputs spiritual power, he can recover his spiritual power to the greatest extent.

Otherwise, in the next seven days, even if there are three Hui Qi Pills, he will definitely not be able to hold out!

Washing and forging the Traceless Sword is very important to Su Yu, he seems to have offended the Luo clan who he doesn't know very well, if Luo Qingdie really instigated the Luo clan to come to him for trouble, it will inevitably feel tricky, not to mention that they have just offended the human king bow spirit, it is difficult to guarantee that it will not be behind the scenes!
