Naruto draws Asura Chakra at the beginning

After a pause, Naruto continued, "In addition, the aura content of the dragon veins there can not only solve the power of the airship, but also be used as an energy source for Hope City,"

The aura content in the dragon veins is sufficient, which can be used as an energy source for the airship.

In addition, City of Hope also currently needs this huge amount of free energy.

Minato and Jiraiya heard the words and nodded in agreement. It was Minato's mission to seal the dragon's veins, and there was still Minato's Flying Thunder God Kunai on the altar there.

"You're all fine later, do you want to go to the refining room with me?" Zi Lai also asked the father and son.

Naruto and Minato both nodded after hearing this. Although they don't practice weapon arts, it's good to gain some knowledge.

After speaking, the three got up, and Minato Shi Fei Lei Shen led Naruto and the others directly to the door of the refining room.

At present, except for the three masters and apprentices, only his two apprentices can come here casually. For others, it is forbidden to enter and exit here.

Opening the door, he explained to the two apprentices who were forging, and then Jiraiya took Minato and Naruto into his exclusive private room.

It's the same as the last time I came here, nothing has changed here, it's still so tidy and clean.

He took out a quarter of the spirit crystal from the storage ring and placed it in the middle of the refining room.

Then he exhaled a mouthful of turbid air, and then began to mobilize his mental strength to lift the amount that could be refined each time into the air.

After a large number of spirit crystals lurked in the air, Jilai also mobilized the spiritual energy in his body to wrap the spirit crystals in the air, and then guide the sky fire in the cyclone.

Skyfire attached to the surface of the spirit crystal along with the output of aura, and then Jilai also began to use the skyfire to ignite the aura.

With a chirping sound, the temperature in the refining room soared rapidly, and the spirit crystal in the air began to melt rapidly on the surface layer. into the air.

Then it is absorbed by the top absorbing impurity container, and stored, waiting for the next step of processing.

With the output of Jiraiya's spiritual energy, the area covered by the sky fire became larger and larger, and the melted spirit crystals were isolated by Jiraiya's mental power, and then continued to calcine the spirit crystals inside.

Since the breakthrough of the technique, Jiraiya absorbed the purple energy to really ignite the sky fire, his flame has been further improved, not only the temperature that can be manipulated is higher, but also the control is more handy.

With the passage of time, all the spirit crystals in the air have melted, and all the impurities inside have been burned out.

Only the blue-white liquid floating in the air remained.

Seeing this, Jiraiya restrained some firepower, lowered its temperature, and kept the spirit crystal in the air in a liquefied state.

Then Jiraiya took out another batch of spirit crystals from the storage ring, and calcined them into spiritual energy as before.

Until the end, all the spirit crystals in the storage ring were calcined, and all the spirit crystals turned into spirit liquid floating in the air.

After all the spirit crystals were purified, Jiraiya began to split the liquid in half with mental power, and then began to increase the firepower for forging.

While forging, he used mental force to compress, and soon the liquid in the air formed a round sphere.

With the refining of Jiraiya, the area of ​​the sphere became smaller and smaller, the blue became more and more intense, and the liquid slowly turned towards the solid.

After the spirit crystal ball lurking in the air shrunk to one meter in diameter, Zilai also increased his firepower again, and at the same time, his free hands also began to quickly pinch the seal.

The runes were condensed by Jiraiya's aura, and then flew to the spirit crystal ball to fuse with them.

It wasn't until Jiraiya finished the last seal that the spirit crystal ball began to emit circles of transparent ripples.

Seeing this, Ji Lai also laughed, his handprints changed, and he reduced his firepower.

After the spirit crystal ball had completely cooled down, Zilai also yelled "Take it!"

Then the spirit crystal ball floated to the top of his head.

With a wave of his hand, the spirit crystal ball floated towards Naruto and Minato.

"Wrap it with spiritual power and appreciate Master Master's masterpiece. Then put it away." Zilai also said proudly.

Naruto and Minato also laughed when they heard the words, wrapped them up with mental power, and then carefully observed the spirit crystal ball in front of them.

The spirit crystal ball was round as a whole, and the runes on it were faintly visible. With the spiritual force probing, Naruto found that although the spirit crystal ball was not activated at this time, there was a little weak suction coming from it.

The object of this suction is the surrounding aura, but because of the isolation of mental power, no aura is poured into it at this time.

"Hey, lecherous fairy, when did you learn the Spirit Gathering Formation?" Naruto asked Zilaiya with a look of surprise on his face.

Following observation, Naruto was able to confirm that the suction force from the spirit crystal at this time was obviously the fluctuation produced when the spirit gathering array gathered the spirit energy.

This is clearly Jiraiya's use of the spirit crystal ball as the needle's eye, with the help of runes, and arranged a small spirit gathering array.

Zilai also snorted when he heard the words, and then said, "I can't learn Juling Formation? Your master, I was also a genius back then, okay?"

There are also many formations in the Artifact Refining Encyclopedia, in addition to the formations there are also restrictions, but the current Zilai is not yet able to practice.

When forging a spirit weapon, it is often necessary to add a lot of formations to enhance the power of the spirit weapon.

Jilai also studied in his spare time, and last time when Kushina arranged the large-scale spirit gathering array, Jilai also helped, contributed a lot, and watched the whole process.

So at this time, Jilai also arranged a small spirit gathering array, which is simply easy to do.

Hearing Jiraiya's confident words, Naruto and Minato both scratched the back of their heads and did not speak.

Seeing this, Ji Lai also shook his head with a lonely expression.

When Naruto and Minato saw him, both father and son coughed, and quickly said, "Teacher, refining things is becoming more and more handy. You haven't studied less during this time?"

"That's right, that's right, the lecherous fairy's operation just now really opened my eyes," Naruto also echoed from the side.

Seeing this, Jiraiya raised his finger and pointed at the father and son. From the degree of trembling of his fingers, it can be seen that Jiraiya's heart must not be as calm as the expression on his face at this time.

Of course, this kind of performance can also be done by Jiraiya. When Minato was in Konoha, he and Jiraiya also stayed together less and separated more, and he also respected Jiraiya besides gratitude.

After being resurrected, he has been staying in Hope City, and gradually he also knows that his teacher is a tough guy on the surface, but he is extremely soft on the inside, and his personality is like an old naughty boy, who loves to joke very much.

Gradually, the master and apprentice got along more and more harmoniously, and gradually started joking.

As for Naruto, Jiraiya is more a grandfather than a master to him.
