"Young Master Rong, the furnace clearing technique you used just now is not ...... The method of burning ashes in the furnace that has been lost for thousands of years ~ 'Aftersound Qianhui'?"

Ouyang Yan stared at the big eyes and said in surprise.

Rong Yu kept replying: "Do you dare to call it Yuyin Qianhui? It's just a small technique, there are twenty or thirty kinds of furnace cleaning techniques, and the refining methods are different, and the techniques are also different from person to person. ”

Yusin Chiki is one of the most advanced techniques of clearing the furnace.

The internal energy of the alchemist was shaken into the inner hall by a little tap on the surface of the instrument, so that the power that penetrated the inner hall was stirred, and then the refining fire was used to quickly grill the floating ashes and the qi, ash, type and instrument spirit left from the last refining in the original furnace.

It seems simple, but in fact, the refiner must understand the texture of the furnace very well, control the sending and receiving of power, and slap it with one palm not only to not hurt the appearance of the furnace, but also to transmit the power to the inner wall.

The power generated is transmitted through the furnace wall to the inner hall and is transmitted in a corrugated manner, shaking off the ashes attached to the inner wall.

At the same time, it uses its own true fire to quickly burn and remove the dross, forming a little spark, and at the same time preheating the inner hall of the refining furnace to achieve the purpose of quickly fitting the spar after entering.

Looking at Rong Yu's smooth operation, as if this was as normal as drinking tea and chatting, Ouyang Yan's heart was shocked again.

After clearing the furnace and slowly sacrificing the heavenly thunder fire, Rong Yu threw five pieces of iron spar into the dingzhong and began to smelt.

"It's ...... Heavenly Fire, you actually have Heavenly Fire!" Ouyang Yan once again couldn't believe his eyes.

Rong Yu controlled the heavenly thunder fire with both hands and gradually wrapped the Nine Dragons Ding, and the size and stability of the fire were the foundation of the refining weapon.

The secret of the Nine Dragons Ding is that it can sense the strength of the refiner to control the fire, and completely transmit the temperature without any difference.

After about fifteen breaths, Rong Yu put in a strand of long hair that Ouyang Kuohai had taken off, gently smelted five breaths, and then quickly threw in the spirit gathering tree core, and with the victory of the firelight, the fierce heavenly fire completely enveloped the body.

With the increase of thunder and fire in the sky, the Nine Dragons Ding slowly floated up, and the original black body of the Ding slowly became clear at a speed visible to the naked eye, and gradually became transparent and larger.

A stick about seven feet long in the Ding Furnace with a light green aura gradually appeared, Rong Yu showed a solemn expression on his face, and with a wave of one hand, the crystal nucleus of the Earth Roaring Lion quickly floated towards the furnace.

Floating above the furnace and half a breath into the heavenly fire, emitting an earthy yellow flame, quickly enveloping the stick, gradually merging and gradually disappearing.

Rong Yu turned his palm into a finger and quickly engraved an inscription on the stick. As the fingers swiped over the Ming culture, countless air nets shone on the stick and gradually submerged.

"Heaven and Earth Infinite Five Extremes Inscription Spirit, Earth Branch Soul Manifest!" A low spirit infusion spell came out of Rong Yu's mouth.

"Is this the infusion?"

Ouyang Yan's eyes widened, and he couldn't help but say.

At the same time, a fine light in Rong Yu's eyes shot into the Nine Dragons Ding, and the red black iron rod actually let out a lion's roar, and a lion's head appeared.

Then the figure of a human man in the black iron rod appeared on the lion, the lion's head was slightly lowered, and he looked subdued, and the picture of nothingness was gradually integrated into the stick.

The stick body rotated rapidly, transforming into a pale yellow, and the wood grain gradually extended to the entire stick body, and the dark iron rod gradually fell into the Nine Dragons Ding.

Removing the heavenly fire, Rong Yu wiped the beads of sweat from his forehead, exhaled a breath of turbidity, and his face gradually returned to ruddy.

"Is it over?" asked Ouyang Yan with doubts.

Bang!, with the sound of impact, Ouyang Kuohai broke in.

"Crazy grandpa, what's wrong, where did the lion beast come from!"

Looking at the two of them staring at him with strange expressions, Ouyang Kuohai knew that he was in trouble.

He scratched his scalp with his hand, smiled innocently, and hurriedly said: "Grandpa, I heard the roar of a demon beast, and I was afraid that you would have something to do, so I slammed the door and came in in a hurry."

"Reckless, am I afraid of a demon beast?" Ouyang Yan pointed at him and reprimanded.

Rong Yu turned around and said to him, "It's just right, the dark iron rod in the furnace is for you to refine, will you try it later?"

As soon as he heard that it was something for himself, Ouyang Kuohai opened his big mouth and smiled, looking at Jiulong Ding not far away.

"Aren't you going to open the furnace yet?" asked Ouyang Yan.

"Open the furnace, who said that the furnace should be opened now, after half a pillar of incense, the cold air of Jiulong Ding will gradually be put into the center of the refining vessel, so that it can return to the natural temperature. ”

"It's cold!

"That's right, this furnace is called the Cold Sky Nine Dragons Ding, and it will exude nine layers of cold qi from the outside in, and this is the reason why this furnace can refine high-level mortal weapons," Rong Yu explained.

"Cold Nine Dragons...... What a familiar name, ah! Isn't it ......" Ouyang Yan raised his head and looked at Rong Yu in surprise, and said unfavorably:

"Isn't it a thousand years ago, the cold air of Situ Hui, the first Dan Emperor in the Shenzhou Continent, is Jiulong Ding!

"Who told you that the Dan furnace can't be refined? There are countless smelting methods in the world, and the refining vessel is also infinitely useful, not knowing doesn't mean that it doesn't exist. ”

Rong Yu once again gave Ouyang Yan a new understanding of refining weapons.

The subtlety of the Cold Qi Nine Ding Furnace is that after the refiner removes the Heavenly Fire, it can operate the cold qi in the Ding by itself, so that the refined weapons can slowly cool down.

In this way, the smelted mortal objects can be melted again and completely fused, so that the precision and fit of the mortal objects can be the best.

After a stick of incense, Rong Yu put one hand on his body, and as soon as his aura was drawn, Jiulong Ding trembled violently, and a stick slowly flew out with a dazzling dark iron weapon.

"Oh my God! it's a mortal product!" Ouyang Kuohai is not a fool, he is knowledgeable

It's just that this mortal artifact faintly attracts him with something, like a friend he hasn't seen for many years or his siblings, and it's a familiar feeling.

Ouyang Yan was fortunate to see the product of the mortal vessel for the first time in his life, and he was even more surprised in his heart, and unconsciously reached out to grab it.

Ang snort!

The Xuantie rod let out a lion's roar, and a huge anti-shock force rushed towards Ouyang Yan, and that force seemed to come from the earth, long and long.

"Be careful! I'll come!" Seeing that his grandfather was about to suffer, Ouyang Kuohai hurriedly jumped and grabbed the black iron rod with one hand.

Strange things happened again, and the originally irascible Xuantie rod suddenly fell silent. is drifting towards him unslowly.

It's like a child finding his father. The Xuantie rod burrowed into Ouyang Kuohai's arms at once, making a buzzing sound of pleasure.

"Take it, I originally refined it for you, it seems that the infusion is very successful, it is born to belong to you. ”

Rong Yu stood with his hands in his hands, his trademark smile on his face again.

"Mine, tailor-made for me, this is amazing, I'll try it!" Ouyang Kuohai turned around and walked out of the door with a stick in his hand.
