Zhang Jian didn't know that when he stepped into the black thunder and lightning area, somewhere in the depths of the thunder pit, the Yin and Yang Dao people suddenly plucked their heartstrings and sensed something.

The black thunder and lightning are extremely terrifying, each of them has great destructive power, if it is placed in the Flood Desolate Continent, I am afraid that a black thunder and lightning can destroy a sect, which is extremely terrifying.

When Zhang Jian stepped into about 40,000 miles, he finally stopped.

"The deeper you go, the stronger the thunder and lightning, with my current strength, the Five Elements Mill Disc has been running to the limit, if I go deeper, I'm afraid it will be counterattacked!"

Zhang Jian frowned slightly, he was always paying attention to the Five Elements Grinding Disc refining thunder and lightning.

Although his supreme divine body is strong, the Five Elements Mill Disc can refine thunder and lightning, turning it into pure energy and fusing it into divine power.

But as the black thunder and lightning became stronger and stronger, his refining ability was also close to the limit, and he had completely reached the limit by now.

Zhang Jian did not force himself to go deeper, but chose to cross his knees on the spot and refine the thunder and lightning.

His strength is now a fourfold Peerless Realm, but it is still far from the peak of the Peerless Realm, and he understands the truth that if you want to hurry, you can't reach it, so he didn't force it, but chose to refine and break through here.

Zhang Jian stopped and sat cross-legged, the black thunder and lightning around him burrowed into his body more quickly, coupled with his deliberate absorption, making the absorption speed twice as fast as before.

And in his dantian, the Five Elements Mill Disc had already rotated wildly, like an electric fan, sucking and crushing the black thunder and lightning, turning it into pure divine power.

In this way, Zhang Jian chose to cultivate on the spot.

And less than 10,000 feet away from Zhang Jian, there was a fierce battle at this moment.

Dressed in a black robe, the mysterious Kuidou King is at war with a thunder beast the size of a hundred zhang at this moment.

This thunder beast was shaped like a brute bull, violent and powerful, and every attack made King Kuidou very embarrassed.

King Kuidou was holding a pocket ancient temple in his hand, which turned out to be the Kuidou Ancient Temple in the Southern Regions.

No one expected that the Kuidou Ancient Temple that shocked the entire Flood Desolate Continent turned out to be a treasure, and at this moment, it was held in the hands of the Kuidou King, constantly urging, and one attack after another was overwhelming, heading towards the Wild Bull Thunder Beast.

Thundered!

This space has been blown up, like boiling water, if it weren't for the Heavenly Realm, I'm afraid its battle fluctuations would be even more violent.

The king of Kuidou is very strong, but this wild bull thunder beast is also very strong, with thunder, faster than lightning, and the aura of destruction is surging, and with one kick, it can trample on mountains and rivers.

The battle between the two was fierce and furious, and fortunately there was no one else here, otherwise it would have been terrifying.

"Kuiliu!"

The Kuidou King suddenly let out a low shout, shaped like a beast's roar, but like a bird's song, extremely peculiar, and with his low drink, the Kuidou Ancient Temple held in his palm suddenly skyrocketed.

I saw a huge willow tree phantom coming out of the ancient temple of Kuidou, rising from the ground, supporting the sky, although it was only the size of a zhang, it was thousands of willows.

At this moment, three wicker strands suddenly flew out of the phantom of the willow tree, like a long whip and a cage, covering all directions, directly binding the wild bull and thunder beast.

"Sacrifice!"

King Kuidou spoke again, and suddenly these three wicker strips were like mosquitoes sucking blood, and they quickly absorbed the Wild Bull Thunder Beast, and finally the Wild Bull Thunder Beast dried up, leaving only a black bead the size of a dragon's eye.

After the wicker absorbed the Wild Bull Thunder Beast, it was quickly withdrawn, and then the willow phantom was also re-submerged into the Kuidou Ancient Temple, and everything seemed to be a dream.

Because of the black robe, he couldn't see the true face of King Kuidou, and he didn't know how much he used this technique to consume.

"Demon Leidan!"

King Kuidou put away the ancient temple of Kuidou, but walked towards the black beads left by the wild bull thunder beast, the black beads were as black as ink, but there was thunder light flickering on its surface.

This is the Demon Thunder Pill, a special pill that can only be produced by mutated thunder beasts here, this pill contains pure thunder and lightning power, and can be absorbed by people.

This alone is enough to prove the value of this Demon Thunder Pill, and there is an even more important use for this Pill.

......

King Kuidou put away the Demon Lei Dan, was silent, and immediately looked for a certain direction and quickly left this place.

Thirty thousand miles away, only a half-emperor-level powerhouse can step in, and at this time, not only the Kuidou King, but also the Nine Infant King, the Han Toad King, and the Guanghan Fairy are also doing the same thing, that is, killing the mutant thunder beast and obtaining the Demon Thunder Dan.

However, Zhang Jian didn't know about this, he still sat cross-legged, absorbing the black thunder and lightning from all directions, and used it to refine it into divine power in order to break through.

The divine power continued to increase, reaching 1,200 Dao, and as Zhang Jian's strength became stronger, his absorption and refining were also strengthening.

Gradually, it was no longer black lightning that drilled into his body, and he took the initiative to absorb black lightning.

Zhang Jian sat cross-legged with his whole person, wrapped in black thunder and lightning, looking from afar, like a giant cocoon.

With the passage of time, Zhang Jian's strength became stronger and stronger, and the speed at which he absorbed the black thunder and lightning became faster and faster, causing a small vortex to form around him.

The vortex was still vague at first, but it quickly expanded, becoming condensed, and its speed became faster and faster, and the force of absorption increased, absorbing all the black thunder and lightning around it.

"Huh, what's going on?"

A figure as bright as the moon just put away a demon thunder pill, feeling the changes in the black thunder and lightning around him, his eyebrows furrowed slightly, and his beautiful eyes suddenly lit up, like two bright moons.

Under Wan Yue's eyes, the Guanghan Fairy discovered the direction of the flow of black thunder and lightning, and his heart moved, and the whole person turned into a ray of moonlight and disappeared in place.

"Could it be that a powerful thunder beast was born?"

King Kuidou didn't go far, he also felt the changes in the black thunder and lightning around him, and after a slight hesitation, he chose the same action as the Guanghan Fairy and went in the direction of the black thunder and lightning.

"Hey, the old man wants to go and see, what's going on?"

A hunchbacked old man in white squinted his eyes, and without hesitation, he disappeared directly in place, this person was the King of the North Sea Han Toad.

The Guanghan Fairy was the closest, and arrived first, and at a glance saw the thunder and lightning vortex the size of a hundred zhang and the black figure in the center of the vortex that looked like a giant cocoon.

"Is it a human? or a thunder beast?"

Looking at the black figure, Fairy Guanghan didn't dare to act rashly, there were too many black thunderbolts around her, even if it was her, she didn't dare to provoke easily.

However, if it were a human being, she hadn't thought of anyone who would have the ability to attract black thunder and lightning.

If it's a thunder beast, it's not like it, after all, most of the thunder beasts have low intelligence and act instinctively like wild beasts.

"Huh!"

Soon King Kuidou and King Han Toad also arrived here, and when they saw the thunder and lightning vortex and the black figure, they were also frightened and puzzled.

The Guanghan Fairy, the Kuidou King, and the Han Toad King are all like the Kunpeng Ancestor, and they are half-emperor powerhouses, but even if they look at the dense black thunder and lightning, their scalps are numb, and they really can't imagine what the black figure inside is. Mysterious Thunder Beast? Or is it a strange treasure?
