At this moment, a large area of gorgeous red glow appeared in the distant sky, it was a fire burning clouds! The colorful glow was extremely gorgeous, it was already sunset at this moment, when a wisp of fiery red shone on Luo Yu's face, Luo Yu subconsciously raised his head, and he couldn't imagine that he had done a long day of useless work on this mysterious white flame, only to see that the sun had slowly set in the west, or it would be dark in a short time, if the fire couldn't do it, then he really had no other way.

Coming back to his senses, Luo Yu immediately used the primary fire attribute spell 'Fire Condensation Technique', which he had mastered a long time ago, and under the operation of spiritual power, a red fireball the size of a fist suddenly appeared in front of him, and as soon as the fireball appeared, the cold air around Luo Yu's body was dispelled away, and the temperature suddenly rose a little.

However, another surprised scene happened, at the moment when the fireball first appeared, the white mysterious flame that was originally rotating by itself was like seeing a favorite thing, and without waiting for Luo Yu to use his spiritual sense to drive it, the white flame suddenly released a stream of white misty light, only to see the red sunset light nearby like a hundred rivers returning to the sea, frantically pouring into the white flame, and then two rays of white and red light appeared in the white flame and rotated rapidly.

After about a moment, the white flame seemed to have absorbed enough red glow, and the whole flame trembled twice and turned into a white streamer, and with a "whoosh" it directly broke into the fireball condensed by Luo Yu.

Luo Yu was shocked when he saw this, although he didn't know what had happened to Bai Yan, but he didn't dare to let the fireball burst, he immediately guarded his mind and increased the spiritual power driven into the fireball, under the infusion control of Luo Yu's powerful spiritual power, the trembling fireball finally quieted down slowly, and at this moment, Bai Yan finally entered the fireball in its entirety.

"Hum...", an ethereal sound, suddenly the fireball burst into brilliance, shooting out several brilliant rainbows, and the red-white misty glow suddenly covered all the surrounding scenery with a layer of red and white, which was extremely magical.

Luo Yu looked at the colorful fireball in his hand in amazement for a while, only to see that the fireball at this time had completely changed, the white and red inside were endless, and the outside of the fireball was like a lotus flower, quietly wrapped by several layers of colorful glow, and several circles of light slowly spread outward, which was really charming.

Looking at the flame in his hand, Luo Yu was amazed for a moment, and he still couldn't help but want to try the power of this strange flame at this moment.

With a wave of his sleeve arm, a spiritual wind suddenly swept towards some of the fallen 'Purple Han Bamboos' on the ground, and those Han Bamboos that didn't have much weight suddenly flew towards Luo Yu, Luo Yu grabbed it casually, and a small section of Han Bamboo appeared in his hand.

Luo Yu lightly held the white flame in one hand, and held the small section of cold bamboo in the other, and slowly merged the two things together with a flicker of his eyes.

"There should be a change this time!" Luo Yu finished speaking, and put the two things together directly.

"Click, click..."

The cold bamboo in the flames immediately made a crackling sound, and the purple on the surface of the cold bamboo began to slowly turn black, and it didn't take long for it to release bursts of burnt smell.

"There is a reaction!" Looking at the purple bamboo slowly dissolving in the mysterious flame, Luo Yu's eyes stared at the whole process motionlessly, for fear of letting go of the slightest detail, about a cup of tea, the purple bamboo in his hand was made into a black powder, and then no matter how Luo Yu continued to burn, the cold bamboo no longer changed.

Luo Yu took the black powder in his hand and rubbed it for a moment, then suddenly moved, raised his hand and put the black powder to his nose and smelled it.

"Huh, this smell... It seems to be the smell of red sandalwood that has been around 500 years old when it is burned. "Luo Yu has smelled this fragrance in Shizun's cave mansion, it is said to have the effect of calming the nerves, but it is a very luxurious item, few low-level immortal cultivators can afford to use it, and this kind of red sandalwood is made from the purple cold bamboo of the five hundred years of ingredients.

It is obviously a purple bamboo that is less than a hundred years old, but after being burned, it turned into a ball of black powder, and it can still exude a fragrance that can only be found in five hundred years.

"Could it be, this white flame actually has the effect of purifying essence!Can increase the growth year!" Luo Yu said in disbelief, after swallowing a few mouthfuls of saliva, Luo Yu felt that his throat was a little dry!

You must know that there is no shortage of elixirs in the cultivation world, and there are countless elixir gardens in many sects, specializing in planting some elixirs, after all, cultivation must be assisted by elixirs, and the most important thing in alchemy is elixir, but even the worst practice qi dispersion requires a hundred years of medicinal materials to be successfully refined, not to mention those elixirs with slightly higher grades.

In this way, it can be seen that what is lacking in the cultivation realm is not the elixir, what is lacking is just those medicinal materials with higher ingredients, many medicinal materials must be obtained by chance, and general cultivation is not of much use, unless it is those that can mature in about a hundred years.

After all, even if you planted this kind of elixir and cultivated it carefully, but no one could wait for hundreds or even thousands of years of growth time, could it be that you were so sure that you could cultivate to the Yuan Infant Stage, even if you could cultivate to that level of Heavenly Cultivation, those medicinal herbs that you planted with the financial resources of your Qi cultivation period would not be used at all at that time.

Therefore, the higher the age of the medicinal herb, the more precious it is, and most of the battles in the cultivation realm are caused by the elixir of these very high years. If this white flame had such a magical effect... That is tantamount to going against the sky, and the cultivation speed is absolutely appalling.

"No... I'm going to keep trying, won't I be dazzled!" Luo Yu was speechless with excitement and stammered.

Hurriedly found some purple cold bamboo and calcined it, and soon finished calcining, and the result was the same as just now, the calcined purple cold bamboo turned into a small ball of black fragrant powder, and then the second one... The third...

As the calcination continued, the expression on Luo Yu's face became more and more excited, and finally he was full of ecstasy, his face was flushed, and his emotions really couldn't calm down.

In just a short time, Luo Yu had almost collected half a bottle of black powder!

"What's going on?" Just as Luo Yu was about to get to the top of the scene, the white flame suddenly separated from the small fireball, and then slowly dissipated in place, and then Luo Yu felt countless white dots surging into his body, and then gathered into a white flame, quietly rotating slowly in the dantian.

Luo Yu immediately woke up from the ecstasy, and hurriedly urged the spiritual power, and the white flame appeared in his hand again, but this time it did not take the initiative to fuse with the small fireball as just now, no matter how Luo Yu urged them, the white flame and the red fireball never showed any signs of fusion.
