Thunder and lightning intertwined, dark clouds eroded the sky like a devil, the scorching sun disappeared, and the thunder continued to shake the valley. In the cave, the stone bowl in front of Baishi, under the infusion of Baishi's spiritual power, finally began to change.

The blood-soaked elixir began to rotate slowly inside the stone bowl, and under the naked eye of the white stone, the speed of this rotation became faster and faster. In the blink of an eye, a red vortex was formed, and an inexplicable heat emanated from within it.

Beads of sweat continued to ooze from Shiraishi's forehead, and when he opened his eyes at this moment, a bead of sweat soaked into his eyes, which was very dazzling.

When the first drop of rain fell into the cave through the gap in the cave, Baishi suddenly let out a soft cry, as if with an inexplicable law of heaven and earth, when the palm of his hand was raised, the things in the stone bowl flew out at this moment. Under the control of his spiritual power, it was suspended between his palms.

But even so, when the contents of the stone bowl were suspended between the palms, they were still within the line of sight of the white stone, and they turned rapidly. The difference is that the way the small red vortex rotates at this moment is not spreading outward, but as if it has become a small red ball in a compressed posture.

Holding his breath, the spiritual power in Baishi's palm was still constantly outflowing, although it was only a trace of it, but it had already made him feel a kind of exhaustion. If you give up now, you will inevitably lose all your efforts!

Slowly closing his eyes, between his teeth clenching, Bai Shi seemed to be overdrawing all the spiritual power in his body. At a certain moment, when the heavy rain had poured down, when his eyes opened again, Bai Shi's outstretched palm suddenly clenched, and then opened again, and within that palm, two almost transparent liliang suddenly gushed out, and immediately hit the small red round ball.

"Bang!"

As the almost transparent liliang hit the small red ball, the ball suddenly made a dull sound, and it burst open at this moment, and the moment the white mist burst open, there were bursts of medicinal fragrance. The original round ball, at this moment, suddenly turned into several small round balls, like pills.

Bai Shi, who was sitting, also fell to the ground in vain at this time, and then gasped heavily, as if this time the refining medicine had consumed all his spiritual energy and exhausted him.

After resting for a while, Shiraishi took a few deep breaths, and could clearly feel a feeling of soreness and numbness all over his body. Struggling to get up, he picked up the pills that had fallen on the ground, a total of nine.

"Fortunately, what is being refined at the moment is only Hehesan...... The foundation building period is fourfold required. If I wait for some pills in refining, the aura in my body is not enough to refine at all......" In the middle of the deep groan, Bai Shi put an elixir in the stone bowl, and then crushed it into powder.

Carefully pouring the lotus into the palm of his hand, Shiraishi stared at it for a moment, and then was silent for a while, as if he was hesitating about something.

He clearly knew that the next step was to take the Hehe, but the load brought by the power of the medicine to his body might make him suffer pain that he had never endured before.

The white fox looked up at Baishi on the side, his eyes rolling, blinking a few times, as if he was curious about something.

Shiraishi's brows furrowed, and at a certain moment, the desire to improve his strength finally made him make a decisive choice.

After throwing the Hehesan in the palm of his hand into his mouth, Shiraishi made a very uncomfortable expression, although the Hehesan had a medicinal fragrance coming out, but after entering it, it was extremely bitter. There was even a strange smell, which made Shiraishi a little disgusted.

Shiraishi knew that this smell was the smell of blood!

Next, what Shiraishi had to do was to sit cross-legged and remove the remaining spiritual power in his body, and speed up the exertion of the medicinal power of this Hehesan.

In silence, Shiraishi's tightly locked eyebrows relaxed, but there was an inexplicable solemnity on his flat face, so that when he put his hands on his knees, there was a faint energy fluctuation that began to ripple slowly from his body.

When the white fox saw this, he let out a slight scream of horror when he stepped back timidly.

At this moment, Bai Shi could clearly feel that a gradually increasing liliang began to shuttle rapidly in his muscles, making his cheeks have a faint flush, and in the whirlpool above his head, there seemed to be a trace of white mist that began to circulate.

But if you observe carefully, it is not difficult to find that this trace of white mist does not emanate from its body, but that trace of aura from heaven and earth, and when it absorbs it, the energy wave emitted by Baishi's body is poured into its body!

Bai Shi in his eyes could clearly feel this trace of spiritual power pouring into his body, but he felt more clearly that the rapidly expanding internal force was squeezing every muscle cell in his body, and this liliang seemed to be about to emanate from the inner canopy of his body, but it did not burst out for a long time, this feeling made him feel as if his body was about to burst open in his brain.

It was precisely because of this illusion that a sense of pain appeared in his flushed cheeks, which was very strong!

His closed lips began to tremble slightly, and more and more aura was instilled in the top of his head, and in an instant, it was like a white mist turning into a trace of white light, constantly stirring above his head!

It seemed that it was because of the abundance of this aura that Baishi's body could not bear the load, and this pressure made his closed eyes suddenly open! But more than that, it is a kind of determination and persistence, this complex look, at this moment, turned into a kind of patience!

Even the palms placed on his knees, in this moment of clenching, there was a powerful energy wave, bursting out, within the energy wave of his fist, there were four white lines that were beginning to squirm, as if they were about to break free from the shackles of this energy at any time!

However, on the periphery of these four white lines, there is a white dotted line that is slowly becoming a reality!

"Five-fold foundation building period...... I'm coming!" Seeing this scene, under this painful torture, Shiraishi endured it, and a kind of madness was released in his eyes, and this madness made him snort softly, and his sitting body stood up in vain, looking at the dotted line that gradually became a solid line, Shiraishi used his crazy consciousness to seem to be trying to portray this line!

His clenched fist opened again, but at an extremely fast speed, when a trace of spiritual energy poured into his body, it clenched impressively, and the energy wave around his fist trembled, and there was a muffled sound, and the white dotted line had already become a solid line in half!

Even so, the pain in Shiraishi's body became more and more intense, and this was because the aura was still pouring into his body. And his strength, uncontrollably, actually floated slowly!

But Shiraishi was not surprised by this, on the contrary, there was an inexplicable feeling of excitement in his heart, which made him open his clenched fist again in vain, and clenched violently under the infusion of a trace of aura. ‘

As the void trembled, the white fox stepped back timidly again, and when he looked up, he saw Shiraishi's face that became even more painful.

The difference is that when Bai Shi clenched his fist this time, he gritted his teeth, and the green tendons on his forehead burst out, and the muscles bulged, and it seemed that he might burst the clothes on his body at any time!

To Shiraishi's excitement, the dotted line finally turned into a solid line under his clenched fist again!

But Baishi's pain did not dissipate because of this, although at this moment, he had reached the fifth level of the foundation building period, but he could still clearly feel that the strong liliang in his body was still constantly expanding, and the pain in his body was becoming more and more intense!

His body did not fall to the ground because of this, the aura that poured into his body above his head became more and more, and his teeth were also at this moment, in the extreme clenching, there was a trace of blood seeping out. And the green tendons on his forehead may burst open at any time. Its appearance is extremely hideous and terrifying!

"This ...... What's going on?"

"Could it be...... The power of this Hehesan medicine is beyond the load of my body?" Although the feeling of intense pain came from his body, Shiraishi, who was suspended in the air, was still speculating about the various reasons for this abnormality!

However, just as he speculated, under the energy wave of his fist, there was a dotted line that was being derived on the periphery of the fifth solid line!

"Sixfold foundation building period!" Seeing this scene, Bai Shi seemed to forget the pain coming from his body at this moment, and in his excitement, he drank lightly, with the blood stains left on the corner of his mouth, and laughed heartily, but it looked extremely distorted.

"It turned out to be a bottleneck...... A sixfold bottleneck in the foundation building period! I can get through it, I can do it!" roared, and the pain squeezed in his body seemed to have a hint of relaxation under his roar, and his clenched fist opened again, and suddenly clenched again, and the sixth dotted line, under the trembling of the void, had a slight change.

Shiraishi clearly knows that if he doesn't grasp this bottleneck at this moment, if he wants to break through the sixfold foundation building period one day, he doesn't know what year and month it will be!

Shiraishi's face was hideous and excited, very contradictory.

But in his heart, there is a belief, an indestructible belief-the sixfold foundation building period!

In the light drink, Shiraishi endured the pain from his body, and under the urging of this pain, there seemed to be a buzzing sound in his brain, which made his consciousness in a trance.

If he relied on his own absorption of spiritual power to break through his strength, his body would not be in too much pain. If you rely on pills, the severe pain is like tearing your heart. Not to mention the pain of breaking through the dual strength at one time, Shiraishi knows this very well!

Time, in the agony of Shiraishi's patience, gradually passed. At this moment, the sixth line was about to completely become a solid line, but the pain from his body made De Baishi tremble slightly at this moment, as if he had lost consciousness due to convulsions from low temperature.

Staring at the sixth white line that was about to become a solid line, Bai Shi seemed to use his whole body to be cautious, under the control of his consciousness, he suddenly clenched his fist again, and the energy wave trembled, and it actually spread, and there was a roaring sound echoing, and the sixth dotted line under its energy wave also became a solid line at this moment.

As if breaking free from the restraints, Shiraishi's heavy eyelids finally closed decisively the moment he saw the sixth solid line appear, and his body suspended in mid-air fell to the ground and passed out......
