In the dark refining stone room, Bai Fu sat on the cold ice stone with his heart facing the sky, his eyes closed, silently using the qi refining method of the "Shen Ao Ba Body Technique", and exhaling the spiritual energy of heaven and earth to refine mana.

"Buzzing ......" The blue blood sword placed beside him suddenly trembled, and Bai Fu slowly regained his strength and looked at it suspiciously.

"Choking ......"

A dull friction sound sounded, and the blue blood sword automatically popped out of the sheath, revealing a half-foot sword body, and the crimson purple sword light flickered, becoming brighter and brighter

......The vibration amplitude of the Blue Blood Sword is getting bigger and bigger, the light on the sword is getting bigger and bigger, and the breath is getting higher and lower, and it is slowly increasing.

"Huh?" Bai Fu was shocked, his heart moved, and he secretly looked at this appearance, some of them looked like a monk had been promoted, could it be that the Blue Blood Sword was going to be upgraded to a real weapon?

"Brush ......" Bai Fu pressed the sword and drew it, and the blue blood immediately came out of its sheath, trembling even more happily in Bai Fu's palm.

Bai Fu closed his eyes, his mind tried to spread out, and he immediately felt a feeling of joy and hunger coexisting.

"It seems that it is going to be upgraded, but it needs a large amount of Jin Yuan essence to urge. Bai Fu's heart moved, he got up from the cold jade bed, and walked towards the practice room while losing the true yuan into the blue blood sword.

After leaving the practice room, Bai Fu entered the treasure room, took the piece of meteorite iron he had collected before in his hand, returned to the refining stone, and sat back on the cold jade bed.

Put the Blue Blood Sword and the Meteorite Iron on both sides of the left and right hands respectively, Bai Fu's eyes are slightly closed, the left hand is placed on the meteoric iron, and the right hand is placed on the blade of the Blue Blood Sword.

The method of absorbing gold and forging a sword is a technique that absorbs the essence of gold and then casts a sword to upgrade it. In fact, it is not limited to swords, but also eighteen kinds of weapons such as swords, guns, swords, halberds, etc., which can be enhanced by this method.

Bai Fu pressed his left hand on the meteoric iron, and there was a cyclone in the palm of his hand, exuding a strange suction, and slowly sucked out a hair-thick white qi from the meteorite.

The White Emperor of Western Gold is an extremely pure metal, and its natural color is white, such as Taibai Gengjin. The white gas that Bai Fu sucked out of the meteorite iron was the essence of the meteoric iron!

The meteorite essence that was sucked out of the meteorite by Bai Fu in a secret method was submerged into Bai Fu's left palm from the Lao Gong acupoint and entered the hand syncope yin pericardial meridian.

The "hiss......" meteorite iron essence, although it was only a trace, was extremely sharp, and it was gently rubbed on the meridians, and the inner wall of the meridians, which was as tough as cowhide, was immediately cut out of a hair-thick wound, and the pain was so painful that he broke out in a cold sweat, and kept inhaling cold air.

Bai Fu hurriedly ran the True Yuan to wrap this trace of meteorite essence tightly, carried the true qi, and took this trace of meteorite iron to swim in the eight veins of the Qi Sutra, and transported it to the Sun and Small Intestine Meridian of his right hand, and to the Shaoze acupoint at the tip of the little finger.

"Bah!" Bai Fu snorted softly, and Zhenyuan rushed, wrapped in the essence of meteoric iron, and went straight into the blue blood sword.

The blue blood sword buzzed and trembled, the crimson purple light soared, and the sword qi shot out three feet, and it stopped after a few breaths.

"It's not enough!" Bai Fu's heart moved, and another wisp of meteorite essence was sucked out, wrapped in true qi and carried to his right hand, and then rushed out of Shaoze's acupoint again, punched into the blue blood sword, and was absorbed by it.

"Sneer...... The crimson purple light of the blue blood sword made a big splash again, and the sword qi shot out four feet, and a layer of black iron dirt fell on the surface. After the sword light dissipated, the red purple sword body could be seen, which was much brighter.

Then Bai Fu ingested six more meteorite essences and injected them into the Blue Blood Sword, and when the eighth essence was sucked away, the meteorite iron was so hard that it was difficult for the sky to melt, and cracks appeared on the surface, and with a snap, it shattered into more than a dozen pieces. Its essence is extracted, and naturally it can no longer maintain a highly condensed and compressed form, and it is inevitable that it will rupture.

Absorbing the essence of the entire meteorite, the sword light of the Blue Blood Sword became even more brilliant, and in the midst of the vibration, a sword qi more than nine feet long shot out.

"It's almost ......" Bai Fu's eyes narrowed, and he grabbed the blue blood sword in his right hand, and the blade rubbed it on the palm of his hand, and the blood of the turtle and snake flowed out.

Stick the blood-flowing left palm on the back of the Blue Blood Sword, wipe it up and down, and wipe the blood of the turtle and snake all over the sword body, and at the same time, two strands of hot and cold true qi erupted from the palm alternately, refining the sword body.

After refining the Blue Blood Sword with its own spiritual blood and true yuan for half an hour, after the huge turtle and snake qi and blood were consumed by fifty percent, and the ice and fire true elements were each consumed by more than two percent, the Blue Blood Sword stopped absorbing essence blood and true yuan.

The double stimulation of spiritual blood and true qi caused the sword qi spewed out by the Blue Blood Sword to slowly grow to one zhang.

The "Ding ......" self-generated sword qi reached one zhang, and the crimson purple light on the blue blood sword soared, and suddenly flicked open Bai Fu's palm, converging the light sword qi, turning into a red purple streamer, which quickly rotated and flew around Bai Fu's body.

"Collect!" Bai Fu's heart moved, and the Blue Blood Sword suddenly stopped in front of Bai Fu's body, the tip of the sword pointed upward, and slowly rotated.

"The real weapon is really not comparable to the spiritual weapon. Bai Fu held the hilt of the sword, feeling the fluctuations of spiritual power on it that were not weaker than his own momentum, Bai Fu couldn't help but exclaim.

"Go!" Bai Fu's heart moved, and the blue blood sword took off his hand, cutting a silver candlestick three zhang away into two pieces, and then flew back upside down, and was taken back by Bai Fu.

"It seems to be a cut below the expected goal, and the strength is too weak. "Bai Fu stroked the sword and groaned, the secret path of blue blood is not a flying sword in the end, but a melee weapon, I will not use the method of flying swords, it is better to use this technique less in the future, it is still a trivial matter to be teased, if the weapon is taken away by the enemy, it will be a tragedy.

"However, it seems that as long as I am within a hundred meters, I can recall the Blue Blood Sword, which is good!" Bai Fu smiled slightly and retracted the sword into its sheath.

There was a lot of blood loss, Xiaobai's face was a little pale, after Bai Fuyun was lucky, he walked out of the practice room with vain steps, went to the Danfang to take some blood-replenishing pills and took them, and then lay down on the cold jade bed, closed his eyes and spirits, and slowly recovered.

The true qi slowly recovered, but the essence and blood couldn't come back for a while, Bai Fu simply stopped refining the qi, and focused on deducing the basic refining of the "Shen Ao Ba Body Technique", and the refining of the spine snake clan's body refining exercises.

It has been ten days since the deduction of this snake clan's body refining method, and it has almost been perfected, but Bai Fu has always felt a little awkward and not smooth, and the exercise method, if it is not smooth, it means that there is a defect, and it is comparable to the exercise of the "Divine Ao Ba Body Technique", he does not dare to try to cultivate at all.

"How can I deduce more, the more awkward I feel, obviously I feel that I am very close to the basic body refining technique of "Shen Ao Ba Body Technique", but the more I feel wrong......" Bai Fu groaned, and secretly said Do you want to try to practice and see, experience it for yourself, and see where the problem is.

Bai Fu thought to himself, "What you get on paper is shallow, and you never know that you have to do it", if you don't practice it yourself, I'm afraid you will never know the source of the problem.

"Then try it!" Bai Fu's heart moved, and a two-meter-long, huge body like a pile of flesh immediately appeared.

"Hiss......" The body of the turtle and snake stepped on the cold jade bed with four feet, the turtle's brain drooped slightly, and the snake's head was holding the snake letter high, looking ready to go.
