The original power in Jiang Fei's body was continuously transformed into fire attributes under the sacrificial and refining techniques of Huoyun Pavilion.

"Get up!" As Jiang Fei stopped shouting, a red flame ignited on his chest.

The red flame burned wildly, and its color began to gradually change during the burning, from the beginning to the red color of gold, and finally the color of the flame was purified to pure gold.

"Swish!" As Jiang Fei's half-familiar sword technique changed, the Chengying Sword automatically flew up, and then the hilt was facing upwards, and the tip of the sword floated downwards above the golden flame.

"Shen!" Jiang Fei's originally closed eyes suddenly opened, and two blazing flames shot out from his eyes. The flames pressed on the hilt of the sword and instantly pressed the Chengying Sword into the golden flame.

"Is this flame actually golden?" Jiang Fei also tried to refine the flying sword for the first time, so he just followed the skills of the Fire Cloud Pavilion to draw a cat and a tiger. He himself was not sure what color the flame should appear.

If Liu Yiyi was present at this time, she would definitely be able to recognize that this golden flame is the purest spiritual fire. This flame can be said to be the best sacrifice fire, which is far stronger than the spiritual fire catalyzed by using the spiritual power in her body.

As for the blazing flames in Jiang Fei's eyes, even if Liu Yiyi saw her, she would not recognize them. Unless it was her master or the Master of Huoyun Pavilion who would recognize them, it was a more pure fire of will!

At this moment, Jiang Fei had no idea what kind of power he had. He just refined the flying sword according to the scriptures of Huoyun Pavilion.

In the golden flame, the Chengying Sword is constantly being purified. Although the forging technology of Mikexing is very strong, the sword refined by technological means cannot remove all impurities. Therefore, under the golden flame, the Chengying Sword narrows down by almost a circle at a speed visible to the naked eye.

The golden flames were tempering the Chengying Sword, and the two blazing flames shot out from Jiang Fei's eyes were not idle. They swam in the golden flames like two dragons and circled around the Chengying Sword!

According to the Huoyun Pavilion's martial arts record, the sacrifice and refining process at this time took 7749 hours, in other words, it was almost four days. Fortunately, Jiang Fei told Bella, Nina and others about the purpose of the trip before he set out. Otherwise, the girls would have to worry about death if he didn't go back for a long time.

There is a way to say that there is no old age and death in the mountains. It means that when a practitioner enters meditation, time passes quickly, birth, old age, sickness and death in the world are like passing clouds and smoke. At this time, Jiang Fei sacrifices the flying sword and refining it. He feels that time has not passed much, but the sun and moon in the sky alternate, and in a blink of an eye, three days have passed.

At this moment, the sacrifice and refining of the flying sword had reached the most critical moment, and the Chengying Sword had shrunk to about the length of only one finger.

"According to the martial arts record, it should be time to add additional materials here." Jiang Fei murmured in his heart, then the ring space was opened, and the remaining half of the bottle of Death God's Mix was put out.

"Damn it, you have to be careful about this thing, it will make me choke!" Jiang Fei carefully wrapped the bottle of the Death God's Mixture with his mental power, and then moved it above the Heart Fire.

"Swish!" Just as Jiang Fei let go of his mental power, the Death God's Mixture fell into the heart fire, the potion bottle was instantly refined, and the Death God's Mixture inside was also evaporated into steam.

"Oh no!" Jiang Fei was shocked. Because he had no refining experience, he did not know that liquid materials could not be directly invested like solid materials, and it would be easy to evaporate and lose.

If it is an ordinary material, then evaporation loss will at most lose some precious materials, which makes people feel hurt. But the problem is that Jiang Fei has invested in the Death God's Mix. If this thing sticks to a little, it can make the starry sky overlord master vomit blood. If Jiang Fei sucks it all over, the effect will be sour and refreshing!

"Swish! Swish!" Just as Jiang Fei held his breath and wanted to use his mental power to dispel the steam of the God of Death, two fiery white dragons in the golden flames suddenly accelerated. In an instant, they absorbed all the black God of Death steam. At this moment, the two fiery white dragons had turned into two black dragons!

"Zheng!" With a sword sound, two black dragons circled and attached to both sides of the Chengying Sword.

"Boom!" The golden flame suddenly surged, and Jiang Fei felt that the energy in his body was instantly drained, and a feeling of powerless fatigue surged into his heart.

"Zheng!" Another pleasant sword sound, the Chengying Sword blew out a dazzling cold light after absorbing all the golden flames. Then it soared into the sky, and the sound of the sharp blade breaking through the air went straight to the sky!

"Boom!" At this time, Jiang Fei found that the sky above his head was surging, and the dark clouds instantly covered the top of his head.

"It's going to rain?" After all, Jiang Fei is not from the Five Worlds. Although he saw the skills of Huoyun Pavilion and knew that Chengying Sword was going to overcome the tribulation, he subconsciously thought about it.

However, even if Jiang Fei reacted in a flash, he could not help Chengying Sword at this time, because Chengying Sword must be passed by himself, and outsiders could not help at all. Moreover, Jiang Fei was as tired as a dead dog at this time, so he could not stand up, let alone help Chengying Sword to overcome the tribulation.

"Crack..." A thunderbolt fell from the sky, and the lightning pointed directly at the Chengying Sword that soared into the sky.

"Boom!" The rising momentum of Chengying Sword has not diminished, and it defeated the lightning in one fell swoop!

"Boom boom boom..." Another seven thunders rolled down, but they were all shattered by the Chengying Sword. At this time, the Chengying Sword was still rushing towards the sky tenaciously.

"Does it take such a big noise to refine a sword?" Jiang Fei murmured in a low voice. He still has too little knowledge of the fairy tale system. It is indeed not necessary to refine a flying sword. But he is also a heart fire and a will fire. Even if he does not use any precious materials, the refined one cannot be just an ordinary flying sword!

"Boom!" Another thunder rolled down. Unlike the previous thunder tribulation, this thunder lightning is not comparable to the previous thunder tribulation in terms of power. If the previous eight thunder energy level was one, then the energy level of the ninth thunder was at least one hundred.

"Zheng!" Chengying Sword seemed to feel the power of this thunder tribulation. It made a sword sound, and immediately followed the black dragons on both sides of the sword and came to life instantly. The two black dragons rushed towards the sky thunder!

"Crack! Boom!" Two black dragons shattered the strongest thunder. Although the black dragon itself seemed dull, the thunder tribulation had been broken.

"Buzz!" A cold light flashed on the Chengying Sword. It recalled two weak black dragons, and at the same time it was also crazy about absorbing the lightning that was broken by the black dragon!
