After knowing how to use it, Luo Yu took out all the yellow bitter gourds in the storage bag and placed them on the ground one by one.

This is Luo Yu's first time refining weapons, without the slightest experience, he naturally did not dare to be sloppy, first of all, the spiritual power of his right hand moved, and suddenly two fist-sized fireballs appeared, one of which was red, and it was Luo Yu's use of fire attribute spells. The fire condensation technique is made of condensing fire spiritual power, and the other is a white transparent mysterious flame, this flame constantly has countless white misty glow converging into small white crystals, and at the same time, there are countless small white crystals that break into a white misty glow, and the cycle alternates in turn, Luo Yu still feels that this white flame is extremely mysterious, and the magic of the effect is unimaginable, it is too against the sky!

Luo Yu Ding this white mysterious flame reverie for a moment, then put these thoughts behind him, wholeheartedly into the refining weapon, only to see his right hand tremble slightly, the palm of the two flames suspended suddenly together, a familiar dazzling brilliance flashed, a white and red mysterious flame suddenly appeared in the palm of the hand, Luo Yu stared at this flame for a moment, then stretched out his left hand, a spiritual wind support, a yellow bitter gourd was brought to the front of the head, Luo Yu carefully controlled the direction of the fluttering of the spiritual power, so that the mouth of the bitter gourd slowly tilted downward, the bitter gourd was filled with cold pool water, so Luo Yu only slightly tilted, then poured out a few drops of white cold water, as soon as the white cold water appeared, the trace of cold air released suddenly made Luo Yu feel smart!

It stands to reason that in order to produce the 'Xuan Ice Cold Essence', it must be a large amount of 'Cold Spirit True Water' that has been continuously condensed and crystallized for about five hundred years, although the water of the Cold Pool obtained by Luo Yu is not the same as the 'Cold Spirit True Water' recorded in the book, but Luo Yu is extremely sure that the water of this Cold Pool will not be worse than the Cold Spirit True Water in terms of coldness.

This is not his random conjecture, according to the records in the "Basic Spells", the flames and cold water that immortal cultivators can grasp are arranged in order according to the different cultivations, the 'innate true fire' released by the monks in the Qi training period using the fire condensation technique corresponds to the 'cold spirit true water' of the ice attribute, the 'three flavors of true fire' released by the monks in the foundation building period correspond to the 'Xuanbing Cold Essence' of the ice attribute, and the fire of the golden pill controlled by the monks in the Yudan period corresponds to the 'Ice Spirit Chill' of the ice attribute, as for what is further up, there is no record.

And this kind of ranking is called the Ice and Fire List by the Immortal Cultivation Realm, it is rumored that the Ice and Fire List was compiled by many predecessors in ancient times, and the Ice and Fire List is full of countless strange fire and strange ice, ranked in order of power, but Luo Yu has never seen what this so-called Ice and Fire List is!

Due to the water overcoming fire in the five elements, the ice attributes of the same level are stronger than the fire attributes, and these are the most common ice and fire attribute spiritual objects listed by Luo Yu in the immortal cultivation world, and there are many other types of fire and ice that are not among them, this cold pool of water Luo Yu just hasn't heard of it!

And if Luo Yu masters the Xuanbing Cold Essence, it is equivalent to having a magical power that can only be used by a monk in the foundation building period, and at that time, coupled with the record of Luo Yu's "Wind and Yang Jin", once he reaches the twelfth layer of cultivation in the Qi training period, he can give birth to the 'Three Flavors True Fire' with the wind to help the fire, which is also a magical power that can only be mastered by a monk in the foundation building period!

Therefore, once he reaches the twelfth layer of the Qi cultivation period, Luo Yu will be able to dissolve ice and fire in one body, and at that time, I am afraid that even an immortal cultivator in the foundation building period will be able to fight against it!

Luo Yu's left hand continued to control the output of spiritual power, slowly tilting the bitter gourd, and then the water of the cold pool also continued to overflow evenly, and the red and white flames of Luo Yu's right palm also quickly moved to the bottom of the bitter gourd, just aimed at the mouth of the gourd, and after the water of the cold pool fell, it was dripped into this flame, Luo Yu controlled it very carefully, and let go of all the spiritual sense, the spiritual power sensed to the very subtle, and the water of the cold pool poured out was no more or less, only a small trace.

"Zizi!" The white cold water made a melting sound as soon as it touched the flame, and then it was melted into a white mist-like true qi by the flame's high temperature, and at this moment Luo Yu was engrossed, not daring to have the slightest distraction, and in less than a moment, the cold water that flowed down first turned into a large amount of white mist and was evaporated by the flames, but this phenomenon lasted for a while, and the cold water that followed it overflowed a little faster than the speed of refining, and a lot of cold water that had not had time to refine slowly condensed into a small white mass under the control of Luo Yu's spiritual power.

At the beginning, the white small ball was just a small white dot, but as the cold water continued to seep in, the white small ball was calcined and melted at a slower rate than the speed at which the cold water flowed in, so the white small ball continued to rotate and grow larger in the flames, this strange phenomenon lasted for a while, and the refining room was shrouded in a thick layer of white mist, and the naked eye could not see at all, but the spiritual sense of the immortal cultivator was not limited by this white mist, and Luo Yu was completely controlling the entire refining process by feeling at the moment.

After a short while, Luo Yu finished refining the water of the cold pool in a bitter gourd, and in his hand there was an extra white ball the size of a goose egg, which quietly stopped in the flame of Luo Yu's right hand and swirled, perhaps because the white ball was wrapped in flames, Luo Yu did not feel the cold air emitted by the white ball.

And the white mist is still constantly emerging from the white ball, it seems that it has not been successfully refined, and Luo Yu did not expect that the cold water in a bitter gourd can refine the Xuanbing cold essence, so he was not surprised to see this scene.

At this moment, Luo Yu completely focused his mind on the white ball, and when he saw that the white ball was getting smaller and smaller, he immediately frowned and glanced at the octagonal diamond-shaped groove on the Biling Han Halberd with his spiritual sense, even if it was refined like this, it would probably be too small, and it would not match the needs of the groove!

After a slight groan, Luo Yu waved his left hand and another bitter gourd was dragged up, and slowly poured out the white cold pool water as he did just now, and suddenly a white silk thread was connected to the white ball in the flame again, because the speed of pouring out was always a little faster than the refining speed, so the white ball began to slowly grow larger under the rotation.

After half an hour, Luo Yu has been maintaining the white ball at the same size as the groove, which is just in line with the octagonal diamond shape, and this half an hour Luo Yu has used up the water of the cold pool of the six gourds, if the cold water of the last gourd is used up and cannot be refined, then Luo Yu can only take some more, and it will inevitably take a lot of effort, it stands to reason that it should not be possible to refine the Xuanbing cold essence of the five hundred years of composition of the cold pool of water, and Luo Yu's Biling cold halberd only needs a small piece of Xuanbing cold essence is enough.
