After a moment, Old Ye's expression also soothed slightly. He opened his eyes and looked at Chu Yun and said, "Okay, let's continue!"

"Old Ye, why don't we refine the cold front another day?" Chu Yun couldn't help but speak when he saw that Old Ye was a little tired.

"It's okay, I'm not as fragile as you think. I'm just a little bit of emotion. If I had put such low-level pills in the past, I just need to wave it casually. Not to mention only fifty pills, even five thousand pills, it's just a blink of an eye." Old Ye blew his beard and said helplessly: "If the vitality in the Qingxu Realm can be sufficient, I won't be so laborious to refine these pills."

"That's OK."

Seeing that Ye Lao insisted, Chu Yun couldn't dissuade him too much. The Qiankun bag in his hand flashed, and three kinds of objects appeared in front of him, namely unknown metal fragments that were dark all over the body and faintly dark patterns appeared on it, strange stones that were red and burnt like fire, and powdery objects that were lightly green in color in a leather pocket.

These three items are the dark-patterned copper, fire meteorite and blue gray needed by Mr. Ye to refine Han Feng. Chu Yun walked forward and placed these three materials with Han Feng in front of Mr. Ye.

"Well, although the purity of these raw materials is not very good, it is enough to refine a low-level Yuan soldier." Old Ye said, stroking his sparse beard.

"The cold front starts!"

Old Ye pointed at the giant blade lying quietly on the ground with one hand, and shouted lightly. The cold light of the giant blade immediately beat. It floated from the ground of Qingxu Realm, but with the other hand, it grabbed the void. The blue gray placed in the leather pocket was grabbed by Old Ye, and with Old Ye's light finger, he wrapped the huge blade slimly floating in the air.

"Rimble!"

Old Ye moved his mind, and the blue flame floating beside him immediately rushed towards the cold front wrapped in blue gray. The moment the blue flame and blue gray came into contact, a hot breath spread from the cold front, and the extremely terrifying heat wave immediately swept across the entire Qingxu realm, and the blue gray wrapped in the cold front of the giant blade immediately burned fiercely.

Chu Yun only felt an extremely hot breath coming to his face, and his mouth and nose immediately became extremely dry, as if his mouth was also burning, and the temperature in the entire Qingxu realm immediately became extremely high.

This drastic change made Chu Yun unable to resist and retreated to the edge of the Qingxu Realm. But even so, he was still very uncomfortable, even his clothes began to crack and become suffocated.

"What a terrifying temperature, no wonder Mr. Ye said that once the blue ash burns, all the medicinal materials will turn into ashes. It's really no exaggeration. Even I will be dried by this hot temperature!"

Chu Yun looked at the scorching blue ash in the center of Qingxu Realm, and his heart was shocked. The scriptures of the Taoist Sutra in his body began to run quickly, flowing into his limbs and bones to resist the burning of blue ash, which brought the terrifying temperature.

The cold front wrapped in blue and gray was also slowly turning red under this terrifying temperature, and gradually melted. Old Ye glanced at the cold front in the flames, grabbed a handful of blue and gray again and sprinkled it on the cold front of the giant blade with one hand.

"boom"

The power of the already extremely hot blue flame immediately rose sharply, and a hot wave of air spread out from the cold front and swept across the entire space.

"The fire meteorite is here!"

Old Ye opened his hands, and dozens of red fire meteorite granules also flew from the ground. Old Ye threw them into the sky above the scorching cold front and floated quietly.

When encountering a green flame, the already red fire meteorite becomes extremely dazzling, emitting a bright red color, like burning small suns.

A trace of red light was gradually emitted from the burning fire meteorite, and under the control of Mr. Ye, he sank into the cold edge of the giant blade. As the red light overflowed, the originally red fire meteorite began to gradually darken, and the originally red color gradually disappeared.

Half an hour later, the fire meteorites floating above the cold front had all turned into grayish-white colors, and with the last ray of red light overflowed, they turned into ashes with a bang.

After sucking in the red light from the fire meteorite, a small impurity slowly fell from it. The originally tough and flat giant blade also became bumpy and full of holes.

"Dark patterned copper particles rise!"

Old Ye waved his hand gently, and the dark-patterned copper particles also floated in the air. Then a stream of blue ash also floated up, wrapping all the dark-patterned copper particles and rushing into the flames of the cold front. As the blue ash burned violently, it slowly melted into copper water.

Drips of melted copper water dripped into the depression of the cold edge blade, gradually leveling the originally uneven giant blade again, and blending with the giant blade under the burning of blue and ash.

"Chu Yun, take out those two magic crystals!" Old Ye said.

"Yes, Old Ye." Chu Yun immediately took out the two magic crystals that had been prepared and threw them into Old Ye. Old Ye bounced his fingers, and two green lights shot out from his hands and sank into the magic crystal. Then the black light of the magic crystal was radiant, and rushed into the green flame with a "buzzing" sound, and then directly penetrated into the hilt of Han Feng's sword and disappeared.

"The magic array of the Yuan, rune seal!"

The moment when the magic crystal sank into the cold front, Old Ye's hands suddenly danced quickly, and one after another of the strange runes turned into blue light patterns from Old Ye's hands, and escaped into the hilt of the cold front's sword.

Half an hour later, the cold front, wrapped in green flames, suddenly let out a sharp sword sound, and the sword body began to tremble continuously, as if there was suddenly a life, and a faint magical power also emanated from the cold front.

"Hey, it's a bit strange!" Old Ye was also slightly surprised. He stared at the shaking cold front in the air, thought for a moment, then smiled and said, "It's good!"

"Feed demon soldiers with wild blood!"

Old Ye suddenly shouted suddenly, and he grabbed the void. The body of the two-winged demon ape among the three chief-level corpses of the wild beasts originally stored in the corner of the Qingxu Realm immediately flew up and rushed into the blue flame. Han Feng seemed to have spirituality and flew up, and with a sword, he penetrated the body of the two-winged demon ape.

"hiss"

The corpse of the two-winged demon ape suddenly dried up quickly at a speed visible to the naked eye. The trace of life essence was absorbed by Han Feng into the sword body, and the corpse of the demon ape also turned into ashes and fell to the ground.

"What? Why is this happening!"

Han Feng's strange performance surprised Chu Yun. Han Feng's performance at this time was very different from the refining process described by Ye Lao Zeng and him.

"Fortunately, I took out the Yuan Dan of the Demon Ape in advance, otherwise I would be in great trouble this time!" Chu Yun looked at the corpse of the Demon Ape that turned into ashes in front of him, and couldn't help but feel scared, and at the same time he was a little painful. The burning of Old Ye not only caused the demon ape's body to be completely damaged, but also the extremely precious animal skin was gone.

"Chu Yun, hurry up, sacrifice true blood to subdue this blade!"

Just when Chu Yun was slightly confused, he suddenly heard Old Ye shouting loudly. He looked up at Old Ye without any hesitation. His fingernails cut through his palms, and a trace of purple and golden blood immediately poured out. Chu Yun's body circulated, and a stream of blood immediately flew out from his palms and shot into Han Feng's blade.

"Buzz"

As soon as Chu Yun's blood touched Han Feng's sword body, it was immediately sucked into it. Then Han Feng made a clear sound, and the blade suddenly vibrated. Strange patterns emerged from Han Feng's huge blade and gathered together to form an extremely mysterious Taoist magic pattern.

"The cold front has already been completed, take the knife!"

Old Ye made seals with his hands and pointed towards the cold front wrapped in green flames. The originally burning green flame immediately flew towards Old Ye and sank into Old Ye's body. The cold front floating in the air immediately flew towards Chu Yun.

Chu Yun stretched out his right hand and caught the re-forged giant blade Han Feng. As soon as the cold Feng started, a feeling of blood connection immediately surged into Chu Yun's heart.

Chu Yun looked at Han Feng and saw that the re-refined cold front at this time was extremely different from the past. At this time, Han Feng was about four feet and five feet long, with a blade seven inches wide, and was dark all over. There were complex patterns on the giant blade, which faintly revealed a trace of magic. The blade was extremely sharp, and it felt like it could hurt both eyes by looking from a distance.

"Old Ye, the feeling of Han Feng is so strange, as if he has life!" Chu Yun stretched out his hand to rub the Han Feng's blade. After a long time, he looked up and said with some confusion.

"Boy, you are lucky. The two magic crystal shattered particles you obtained in your hand are very extraordinary. They have a strange power that actually tempered this cold front with a trace of magic, making it possible to further advance!"

Old Ye took a deep breath and said, "It is precisely because of this that I temporarily used the body of the double-winged demon ape to refine this blade to advance. The cold front in your hand has completely surpassed the power that the Yuan soldiers of the Zhufu Period should have. Demon patterns have formed on its blade."

"Creating a demon pattern?" Chu Yun glanced at the mysterious pattern on the cold edge of the blade, and his heart moved, and he couldn't help but ask excitedly: "Old Ye, you mean..."

"Yes, it is already a Yuan soldier in the Dao pattern stage at this time. Moreover, due to the magic crystal, its patterns are more demonic, but it is more appropriate to call it the Dao pattern demon soldier!"

Old Ye nodded and said, "When the weapon is advanced to the Taoist Yuan soldiers, the grade can be improved through the continuous tempering of the user. However, because your cold front is magical, it requires a lot of blood and life essence to feed it!"

"The demon soldiers in the Daopao period are so good. According to rumors, the weapons used by the Marquis in the Marquis' Mansion are just a top Yuan soldier in the Mansion period, and my hand is actually a weapon in the Daopao period."

Chu Yun stroked the demon soldier Han Feng who had a close response to him in his hand, and said secretly happily in his heart: "With this demon soldier in hand, when I ascend to the Mansion and mobilize the vitality of heaven and earth, I can also circulate in this great wilderness."

"kindness?"

Just as Chu Yun held Han Feng in his hand and was delighted, his heart suddenly moved, and he could sense that Tengtian, who was left behind from Qingxu, was constantly digging the jade pendant with his little claws.

"Is something happened?" Chu Yun's heart moved, stood up and said to Old Ye: "Old Ye, there seems to be something wrong outside, I'll go and see!"
