After the Blood Cloud Sword was thrown into the pillar of fire, all of a sudden, all the heat in the pillar of fire almost poured into the Blood Cloud Sword, and the temperature in the entire refining room became cooler.
The Blood Cloud Sword was burned by the pillar of fire, and in just a moment it turned red.
At this time, Mo Xuan looked solemn. He continuously made hand seals, which turned into a ray of light and hit the Blood Cloud Sword in the pillar of fire.
After these handprints were imprinted on the Blood Cloud Blade, countless runes suddenly spread out from the Blood Cloud Blade and transformed into a rune light ball, surrounding the Blood Cloud Blade and spinning continuously.
During this period, Mo Xuan kept making hand seals with his fingers at such a fast speed that Chen Lei was dazzled. If it weren't for Chen Lei's powerful spiritual power, it would have been difficult for him to remember such complicated hand seals of Mo Xuan.
And one after another, light seals flew out from Mo Xuan's hands and continuously flew towards the Fire Cloud Sword in the fire column, making the Fire Cloud Sword gradually become extremely transparent and crystal clear, and some impurities were gradually refined out.
This Blood Cloud Sword was originally considered a rare spiritual treasure, but looking at Mo Xuan's appearance, he was actually trying to further temper the Blood Cloud Sword. Obviously, this was an extremely difficult task.
However, Mo Xuan tried his best and actually made the Blood Cloud Sword in the air shrink a circle, becoming extremely crystal clear and shining with an intimidating cold light.
Afterwards, two more Yuan Beasts' Nascent Souls appeared in Mo Xuan's hands. With lightning speed, he threw them directly towards the Blood Cloud Sword. In an instant, the two Yuan Beasts' Nascent Souls hit the Blood Cloud Sword. Then, the restriction that sealed the two Yuan Beasts' Nascent Souls was broken, and the two Yuan Beasts' Nascent Souls turned into two cold lights and tried to escape.
However, the blood-colored runes that surrounded the Blood Cloud Sword were like sharks that smelled blood. They pounced on the two Yuanyings, the snake and the tiger, and surrounded them. Then, they disappeared into the Blood Cloud Sword.
Finally, all the runes in the Blood Cloud Sword returned to the Blood Cloud Sword itself. Countless extremely complex patterns were imprinted on the Blood Cloud Sword itself, which contained the ultimate principles of heaven and earth and was extremely mysterious.
The blood-colored runes kept flowing on the blade, gradually merging the two Yuanyings of Silver Snake and White Tiger into one.
The originally blood-colored blade gradually turned into silver-white, and finally, into the color of white jade. The white jade-like blade then gradually changed and turned into a transparent color. On the transparent blade, there were blood-colored veins that were thousands of times thinner than a hair, interwoven into a snake and a tiger, two patterns, imprinted on the upper and lower sides of the blade.
Finally, the appearance of this Blood Cloud Sword changed drastically. It became slightly narrow and long, similar to a snake's body, full of streamlines, transparent throughout, as thin as a cicada's wing, and shining with cold light. From time to time, colorful rays of light flashed across the sword.
"puff!"
Lord Mo Xuanfeng spat out a mouthful of blood, his expression waning.
Afterwards, Mo Xuan closed the Fire Eye, and the newly refined Blood Cloud Sword was immediately completed.
However, the appearance of the Blood Cloud Sword has changed drastically at this time, so it would be a bit inappropriate to call it the Blood Cloud Sword anymore.
Chen Lei looked at Mo Xuan and asked with concern: "Master Mo Feng, are you okay?"
