The melodious sound of the sword reverberated in Su Bai's body, and the vigorous energy surged in his limbs and bones. Su Bai's mind moved slightly, and only the silent sword idea and only the sword idea roared out, mixed with the vigorous energy, and quickly integrated in the operation.

Then, under Su Bai's control, he rushed to the bones and flesh, which made Su Bai's flesh glow faintly red.

"It takes about seven minutes to refine two jars of blood essence..."

When Su Bai's blood essence completely dissipated, his eyes just opened. In an instant, Kunpeng's wind wings spread behind him, and his body rushed towards the blank area in front of him like lightning. That area was right in the middle of two Reiki storms. On the surface, it looked calm, but the power surging inside was very terrible.

The oppression twisted Su baijunyi's face, and a trace of blood penetrated through his pores.

"Shit... It's terrible. I didn't expect that the residual power of the two Reiki storms would be so terrible together." Su Bai clenched the oppression and endured the residual power of the terror and walked forward. When he left the previous heaven and earth, there was a magnificent Reiki wind storm, the terrible energy swept away, the boulders collapsed and the earth shook.

At this time, Su Bai turned around and looked at the scene with lingering fear. He was a little afraid and said, "fortunately, for the sake of insurance, he left three minutes in advance. If he delayed another minute, it would be very difficult to leave."

"However, this adventure proved my guess to be correct. Next, as long as I use this law, it should not be difficult to survive in this world." Su Bai looked around and looked at the Reiki storm around again.

When the aura storm dispersed, Su Bai took out his body, took out his blood essence and refined it easily.

Day after day, Su Bai repeated the same actions like a machine and never stopped. The repeated refining of essence and blood made Su Bai's Qi and blood stronger and his physical strength more and more terrible. Finally, the bones in Su Bai's body were filled with a metallic luster.

The progress of his physical body is almost negligible for the pressure generated by the Reiki storm in the world.

The Reiki storm here can kill the strong in the Taoist base.

Therefore, Su Bai always kept the most cautious state and did not dare to relax. Once relaxed, his body would be affected by the aura storm around him in the next moment.

Boom!

The majestic aura of heaven and earth is like dark clouds, sweeping all over the world, setting off a towering aura storm.

Countless aura storms raged, and a thin figure loomed in it, swaying out a dream like body method.

"Congratulations! Kunpeng's wind wing proficiency has been increased by 100 points..."

"Congratulations! Kunpeng's wind wing proficiency has been increased by 100 points..."

The sound of the system echoed in Su Bai's mind all the time, but Su Bai didn't hear it. He looked dignified. Every time he stepped out, the wind wing of Kunpeng would lift a strong sword wind behind him, tear away the surging pressure in front, and then Su Bai's body would sweep more than ten feet.

It was not until he rushed out of the world that Su Bai breathed a sigh of relief. His eyes closed slightly and looked at the proficiency of Kunpeng's wind wing. He saw that this proficiency had changed dramatically compared with the past, with hundreds of thousands of proficiency, which also meant that Su Bai had reached the level of perfection of Kunpeng's wind wing.

Compared with the Kunpeng wind wing, the Kunpeng wind wing has a very different distance.

The dark wind wing of Kunpeng was shaking gently behind Su Bai. Compared with the past, the wind wing of Kunpeng was more slender, and its length was about Zhang long. The mysterious lines spread on it, filled with ink like luster all the time, cold and ferocious.

"The key point of Kunpeng wind wing is to break through, the speed brought by breaking through all constraints..."

"As far as Kunpeng is concerned, its bondage is the sea of the northern underworld, while as far as I am concerned, bondage is the ubiquitous aura storm in front of me. The terrible pressure is constantly tempering my body and honing my body method..." looking at the huge proficiency, Su Bai's mouth involuntarily rises. If this goes on, he will cultivate Kunpeng's wind wing to the realm of a generation of masters, point the day and await for it.

"The Kunpeng wind wing of the master's realm is far better than the master in terms of speed and flexibility..."

"At that time, I'll be more sure to leave here." the residual shadow dispersed, and Su Bai's body fell in front of the broken gully. When the Reiki storm in front of him dispersed, he rushed out again.

Over and over again, Su was defeated in this terrible and desolate death penalty area and experienced hell like training.

There is no sun or moon, no day or night, and the sky is always gray.

The only thing that can make su Bai remember the loss of time is the less and less blood essence in the ring. All those blood essence were refined by Su Bai, but most of them were integrated into Su Bai's flesh and bones to strengthen his flesh.

Even so, after accumulating, a lot of blood essence was refined by Su Bai into my only sword Qi, surging in his body, and finally poured into the Dan field.

On this day, when Su defeated the two jars of refined blood, a strong breath slowly spread out from his body. The intensity of this breath has exceeded the congenital peak.

"Congenital duality..."

Su Bai's eyes were filled with uncontrollable joy. The only sword Qi in his body was pouring uncontrollably into his Dantian at the moment, and the sea of Qi roared in all directions.

"I didn't expect to make a breakthrough at this moment, but it was expected. My cultivation was originally at a congenital peak, and these days, although I use most of my essence blood to strengthen the flesh, after all, some essence blood has been refined into..." Su Bai murmured softly. He refined countless essence blood these days. If I use these essence blood to improve my cultivation, His accomplishments are definitely not limited to congenital duality.

However, Su Bai was not disappointed and regretted the result. There was a sentence recorded in both the sword demon Heart Sutra and the only sword formula: "the body is like a tool, and the cultivation is like water!

"Only a stronger body can carry stronger accomplishments..."

"The stronger my physical strength, the easier it will be to practice in the future..."

"At that time, as long as I had enough blood essence or merit points, there was absolutely no bottleneck to break through." Feeling the power surging in his body, Su Bai's eyes were filled with excitement. His physical strength was several points stronger than those who were born with seven or eight weights. Now if he met someone with about six weights, even if he didn't use the pseudo four elephant Xingxiu sword array, he was confident to kill him.

"It's a pity that there was no blood essence left in my hand..." Su Bai got up and left the area. With the improvement of cultivation and physical strength, he could not bear the pressure surging around him as hard as before. At least the blood in his body would not penetrate through his pores because he couldn't bear it.

"When all these blood essence have been refined, my physical strength should be comparable to that of the congenital August 9th reformer." Su Bai took out the blood essence again and went to the next area to refine it easily.

The boring days were spent in cultivation, and the fact was just as Su Bai thought. After he refined all his essence and blood, his physical strength was no less than that of the eight or nine innate practitioners, and his cultivation was close to the three innate peaks.

Therefore, Su Bai could only take out the last jade bottle containing four kinds of blood essence.

At the moment when the jade bottle was just taken out, an extremely violent breath came out of it.

"Four kinds of blood essence is equivalent to more than a hundred drops of three kinds of blood essence... It took me several hours to refine three kinds of blood essence at the beginning, but now my physical strength and cultivation are stronger than at the beginning. If I re refine Kunpeng's efforts at this time, it shouldn't take so long, but it can't be solved in just ten minutes." Su Bai frowned slightly and looked around at the raging Reiki storm. He hesitated. If he couldn't refine the blood essence in ten minutes, the Reiki storm would tear his body apart.

"Can we only give up refining blood essence here?" Su Bai looked dignified. His physical strength was ok now, but it was obviously not enough to get out of the restricted area with such physical strength. He could only continue to improve his physical strength

"The duration of Reiki storm is related to the energy contained in Reiki storm... The more terrible the energy is, the longer the Reiki storm lasts..."

"The formation of Reiki storms here is uncontrolled... So the energy surging in them is different..."

"But if I can control the formation of this aura storm and gather the aura from the world, the duration of this aura storm should be longer..." Su Bai was not in a hurry to give up, but fell into meditation. After some thinking, he planned to try, "Just as master Luo Liuli did, gather the sword array and lead it to collapse, forming an energy storm between heaven and earth."

"The energy storm caused by ordinary sword array is always limited... You can only use Zhoutian star sword array. In this way, the energy storm formed is terrible."

"But there is also a drawback. Once an energy storm is formed, if I can't avoid it, I'm afraid I'll have to explain my life." Su Bai raised his eyebrows involuntarily. He didn't hurry to try, but thought out some details. After all, the spirit of heaven and earth here is more magnificent than the edge of the restricted area. The energy storm caused by crashing the sword array here is obviously more terrible.

"Try the one yuan sword array first." Su Bai quickly gathered a sword array with his hands. The rainbow like sword shadow, carrying the majestic aura storm, swept towards the sky under Su Bai's control.

At the moment when the sword array just swept a hundred feet, it couldn't bear the pressure between heaven and earth, collapsed and set off a terrible energy storm.

Kunpeng's wind wings spread out, and Su Bai's body swept towards the rear to avoid the energy storm. Calculate the duration of the energy storm, "three minutes..."

"Not enough!" Su Bai's hands changed again and condensed the sword seal. This time it was Liangyi sword array, but the energy storm lasted only seven minutes.

Sancai sword array, ten minutes!

Zhou Tian star Xuanwu sword array, more than 20 minutes.

Zhou Tian star and Taiyin sword array, more than 20 minutes.

Zhou Tian stars Green Dragon Sword array, more than 20 minutes.

"I can only choose the sky star pseudo four elephant sword array..." Su Bai frowned. Two huge virtual shadows condensed over him and dominated between heaven and earth. The aura between heaven and earth poured madly. The Xuanwu virtual shadow and the green dragon virtual shadow roared up at the same time and swept away into the void until they collapsed.

Boom!

The deafening roar rose into the sky, and the aura of heaven and earth within a radius of more than a thousand feet was uncontrolled, pouring towards that area, setting off a heavenly energy storm.

More than a hundred feet away, but the remaining power swept away in an instant. Su Bai's body was the first to bear the brunt. Like being hit hard, his blood vomited wildly, and his body retreated towards the rear in confusion, with blood gas surging wildly in his body.

Regardless of his injury, Su Bai stared at the terrible energy storm and calculated its duration: "ten minutes... 20 minutes... 40 minutes... 70 minutes... 100 minutes..."

"Enough!" when the energy storm dissipated, Su Bai couldn't wait to rush out
