Every time the Purification Bead advances, it needs more and more poison, if it weren't for the majority of the poison pills in the Dan Domain, I don't know when it will take to get to this point!

On the surface of the beads, green dominates and cyan is only a secondary color, but this color transition stage takes a long time.

The Purification Bead is different from ordinary poison pills, every advance is earth-shattering, and this new breakthrough requires even more poison!

After another hour, the color of the beads completely turned cyan, and the aura emanating from above was more than several times more terrifying than that of an ordinary five-grade poison pill.

After this bead advanced, there was a little more spirituality, and he was no longer crazy about grabbing resources with Gu Qing, the light dimmed, and it slowly fell into his body and did not reappear!

At this time, two-thirds of the five-grade poison pills in the Dan Domain had disappeared, and most of them had been absorbed by the Purification Beads, except for a small part devoured by Gu Qing.

It is precisely because of this reason that the purification bead can advance rapidly, from the fourth-grade poison pill level to the fifth-grade poison pill!

Now, the Purification Bead no longer robs Gu Qingming of the poison, and protects him in the sea of poison again.

Clusters!

The Northern Underworld Poison Body continued to run non-stop, and the Nine Rivers became much wider, like nine upside-down waterfalls, sticking to Gu Qing's back, inseparable.

There are more than eight hundred poison pills left, swishing towards Gu Qing, waiting to be devoured and refined!

These poison pills are all five grades, and they are poison pills that can only be refined in the realm of the poison king, but they have existed for too long, and they are ordinary pills themselves, so the toxicity is far less than the moment when they have just been refined.

Burst!

The sound of the elixir disappearing continued to sound, and it was like a firecracker.

Regardless of whether these poison pills were new pills or not, the five-grade poison pills were not covered after all, so that Gu Qing's strength steadily climbed to the peak of the half-king realm.

When the last poison pill disappeared, he still hadn't broken through, and his strength had reached the peak of the peak of the half-king realm, but no matter how hard he tried, he still couldn't break through the film-like bottleneck.

He slowly opened his eyes and swept around, there was no poison pill left in the Dan Domain for him to refine.

"This Poison King realm is really not covered, it's so difficult to break through!" Gu Qing exhaled a breath of turbid air and said helplessly.

In an hour, if his strength cannot be refined again, his aura will fall again from the peak of the half-king realm, and fall to the peak of the nine-star poison handsome little by little.

Once it falls, the breakthrough will be a complete failure!

In an hour, you must break through the bottleneck and enter the poison king, otherwise, all your achievements will be wasted!

There is no poison pill in the Dan Domain, and all the strange poisons on his body have been refined, and there are no other five-grade poison pills prepared before the breakthrough, it seems that this time he is really desperate and helpless.

Just when he was desperate, there was a click, a big crack appeared directly above, and a figure fell with a bang, and in a blink of an eye, it was in front of him, it was Yun Yi.

After Yun Yi appeared, he first glanced at the surrounding space, and when he saw that Gu Qing was safe and sound, he said in surprise: "Big brother!"

"Yun'er, why are you here?"

Yun Yi smiled slightly, and said: "Grandpa Tianji said that you are in trouble, let me help you! He told me that there is a hidden little guy in this space, let me help you catch it! I just came in and felt its breath, I went! Hehe!"

After finishing speaking, without waiting for Gu Qing to reply, his figure flashed, turning into a thunderbolt and disappearing into the depths of the Dan Domain.

The second monk of Gu Qingzhang was puzzled, shook his head and smiled bitterly, and waited quietly in place.

A moment later, there was a low crackling sound in the distance, and from time to time there was a flash of thunder, and the brightness was amazing, as if someone had thrown a thunderbolt.

Immediately afterwards, an incredible scene appeared, small lightning suddenly appeared in the entire Dan Domain, an astonishing number of them, all of them fell from the sky, except for the stone platform where Gu Qing was located, no one else was spared!

Gu Qing was a little curious, stretched out his finger and touched a small thunderbolt, ah, there was a light sound, his body was shocked and he took a step back, his fingers hurt, like thunder and fire, and he was in pain.

"What kind of thunder and lightning is this, how can it be so powerful?" urged the poison on his body, and drove out the thunder and lightning that entered his body little by little.

Rumble!

In the distance, there was a deafening sound of fierce battle, as if Yun Yi was fighting with something.

"Who the hell is this Yun'er? I'm not afraid of these thunderbolts. Gu Qing was amazed, shook his head and thought hard.

After a short while, a bolt of lightning flew towards this direction, and everywhere it passed, all the thunder and lightning around him were dispersed.

The speed of this thunder light is very fast, twice as fast as the Vientiane Thunder Shadow of the ancient Qing Dynasty, and in the blink of an eye, it is in front of you, it is Yun Yi!

Yun Yi didn't have any injuries on his body except for his breath being a little disordered, and as soon as he stepped on the stone platform, all the thunder and lightning in the Dan Domain disappeared, disappearing without a trace, as if he had never appeared.

"Yun'er, where have you been, are you okay?" Gu Qing glanced up and down at Yun Yi and asked with concern.

Yun Yi's face was full of victory, he smiled, stretched out his little palm, and said happily: "Big brother, I wasted a lot of effort to catch this little guy!"

Gu Qing was stunned for a moment, her eyes fell on her palm, and she saw a round bead flashing with cyan thunder light scurrying in her palm.

Lei Zhu seems to have spirituality, does not like to be trapped by people, flashing thunder and lightning everywhere, but no matter how powerful it is, Yun Yi always has a black and white thunder in his hand to block it and prevent it from leaving.

"Is this the Cangying Thunder?" Gu Qing looked at this thunder bead up and down, and felt that this cyan thunder and lightning was a little familiar, as if he had seen it somewhere, and after a while, he shouted as if he had thought of something.

"Big brother is so smart, this thunder and lightning is the Cangying Thunder! This thunder and lightning is so fierce, Yun'er almost didn't subdue it! Hmph! Nasty stinky thunder!" Yun Yi said angrily.

"No, this bead is not a simple thunder bead, it should be a poison pill!" Gu Qingnai is a poison refiner, and he is quite sensitive to poison pills, so he observed the thunder bead again and said his conjecture.

"Big brother, you're not wrong at all! This little guy is a poison pill, a poison pill refined by someone else with a trace of Cangying Thunder!" Yun Yi said.

"Use thunder and lightning to refine the poison pill? Who actually has such an all-powerful alchemy? Although this poison pill is a fifth-grade poison pill, its toxicity and quality can already rival that of an ordinary six-grade poison pill! Hey, there is really a heaven outside the sky, and there are people outside the world!" Gu Qing was shocked, and his mood could not be calm for a long time.

"It's also the first time I've seen this kind of poison pill!Grandpa Tianji told me that he said that this poison pill is called Cangming Pill, and it was successfully refined with a trace of Cangming Thunder and dozens of kinds of thunder grass, and it came from the hands of a seven-grade poison refiner!" Yun Yi explained.

"Seven-grade poison refiner, is it any wonder? Ordinary poison refiners don't use thunder and lightning to refine the pill, as soon as they come into contact with this thunder and lightning, they may be bruised! What does the old man of Tianji mean, let me use this poison pill to break through the realm of the poison king?" Gu Qing said.

"Grandpa Tianji said that as soon as this Cangming Pill is refined, a seed of Cangming Thunder will appear in the body, and this thunder poison will grow slowly!" Yun Yi continued to speak for the old man of Tianji.

"The seed of the Dark Thunder, the growth of thunder poison?"

"Grandpa Tianji also said, you have comprehended the Void Netherworld Realm, this Immortal Thunder is more suitable for you! He asked me to tell you that this thunder poison can grow by killing people, and the more people you kill, the faster it will grow!" Yun Yi continued.

"What, grow up by killing?" Gu Qing was completely stunned. After being silent for a moment, he smiled bitterly, and took the Cangming Pill from Yun Yi's hand, and after touching it, the cyan thunder and lightning directly slashed him backwards.

After Yun Yi saw this, his face flashed with anger, and he yelled at the Cangming Pill in his palm: "Breaking the thunder poison, if you are disobedient again, the old lady will kill you and split you into ashes!"

As soon as the words fell, the black and white thunderbolt slashed on the Cangming Pill, instantly making the Cangming Pill become docile. After doing all this, he smiled and handed the Cangming Pill to Gu Qing again.

Gu Qing nodded lightly, took it in his hand, and found that this poison pill was much more docile, so he smiled and swallowed it.

"Big brother, don't worry about refining. With me here, this Cangying Poison doesn't dare to play tricks!" Yun Yi sat cross-legged and began to help Gu Qing protect the Fa.

There are thirteen kinds of thunder poison in the wild world, each of which is unruly and untamable, and a strange scene appeared, Cangming Pill became very docile under the deterrence of Yun Yi, docile like a little sheep, obediently let Gu please refine, and did not resist at all.

Gu Qing's strength was already at the peak of the half-king realm, and with the help of the Cangming Pill, he easily broke through the bottleneck and successfully entered the realm of the poison king.

The Cangying Thunder Poison is a well-known poison, and its power is no less than that of ordinary strange poisons, and it is a high-grade poison.

The purification bead is quite greedy, and naturally it will not let go of the Cangming Thunder Poison, making waves in the poisonous sea of the ancient Qing Dynasty, and began to snatch and refine the thunder poison, and the tragic situation appeared, and it was directly blocked back by the Cangming Pill.

The space around Gu Qing is constantly distorted, and the power of black and white space emerges one after another, intending to destroy the entire Dan Domain!

"This is the strength of the Poison King's powerhouse?" Next to him, Yun Yi showed a look of surprise.

With Yun Yi by his side to protect the Dharma, the refining of the Cangming Pill was surprisingly smooth, and there was no problem from beginning to end.

After complete refining, Gu Qing's strength was completely stabilized to the peak of the two-star poison king!

He was quite satisfied with this result, opened his eyes, and with a wave of his hand, a spatial crack was directly torn open.

"This is the power of the Poison King's powerhouse, it's so powerful!" he raised his palm slightly, smiled slightly, and said.

"Congratulations to the eldest brother for becoming a strong drug king!" Yun Yi was quite happy, jumped up, and pulled Gu Qing's arm and said.

Gu Qing smiled faintly, glanced at the Dan Domain, stretched out a palm, tore open a spatial crack, and returned to the tenth floor of the Wanjing Pavilion with Yun Yi!

(PS: Chapter 300, Gu Qing's strength has also advanced to the realm of the Poison King.) In the future, if you fight, you can use the poison qi gong method properly, haha!)
