Chu Heng's divine sense searched the bottom of the Thunder Pond little by little, not letting go of any place.

Even if the horns are ugly, Chu Heng has to investigate it again.

Ouyang Xingchen didn't bother Chu Heng, just waited quietly.

But where the formation exists, no matter how hidden it is, it is impossible not to leave any traces.

But Chu Heng searched most of it, but he didn't find any trace of the formation.

Chu Heng's divine sense continued to investigate, and it was more rigorous than before, but there was no trace of the formation left, as if there was no formation here at all.

"Are you sure, there really is a formation here?" It wasn't until he had explored the entire bottom of the Thunder Pond and found no trace of the existence of the formation, Chu Heng couldn't help but ask Ouyang Xingchen.

"It should ...... Maybe...... Probably, almost...... exist. Ouyang Xingchen was also a little uncertain, and said hesitantly.

"Then how did you get in last time?" Chu Heng patted his forehead and said helplessly.

"I just got in by accident, just by chance. Ouyang Xingchen said.

"Then do you still remember, what changes did this thunder pool have before you went in?" Chu Heng asked, "Or, what special things appeared?"

"At that time, I was here to receive the Thunder Refining, and I didn't even notice the situation around me, and when I woke up, I appeared inside. Ouyang Xingchen said: "As for how I got in, I don't know." ”

"Then how do you say that there is a formation here?" Chu Heng frowned.

"I guess. Ouyang Xingchen said.

"Poof!" Chu Heng almost spurted out a mouthful of old blood, you just made Lao Tzu probe for so long based on a guess?

"By the way, before I went in, I seemed to vaguely feel that the entire thunder pool had become different, as if there was a special power. Ouyang Xingchen tried his best to recall the previous situation and said: "That power is very domineering, full of the smell of destruction, and at the same time there seems to be a kind of longing, as if people are hungry and want to eat, that's right, that's it!"

Hearing this, Chu Heng's brows furrowed tightly.

But if any alien spirit wants to grow, it needs to absorb endless heaven and earth energy, just like the Qinglian Holy Flame in the process of growth, it will also devour countless demon beasts and strike a martial artist.

"Since the Qinglian Holy Fire needs to devour demon beasts and martial artists to evolve, does the thunder spirit also need to devour living beings to grow?" Thinking of this, Chu Heng's eyes suddenly lit up, and he secretly said in his heart.

Ouyang Xingchen said that when he went in, Lei Ling was about to transform, and since he wanted to transform into a shape, he might need an extremely large amount of energy.

Therefore, Ouyang Xingchen didn't touch the formation here by chance at all, it was most likely because Lei Ling wanted to eat, and he instinctively reacted to get Ouyang Xingchen in.

But I don't know why Ouyang Xingchen picked up a life and was not devoured by the thunder spirit.

"Maybe there really is some kind of formation here, but with my current cultivation, I can't find it at all. Thinking of this, Chu Heng felt a little reliable, and secretly said in his heart.

After all, the Cloud Thunder Sect is a six-rank sect, and the array mages in the six-rank sect must be extremely strong.

This formation is also for the purpose of hiding Lei Ling, and it will definitely be arranged more hidden, and it will definitely not be easily discovered.

"Instead of bothering to find a formation and then break it, it's better to let Lei Ling take the initiative to find himself and get himself in. The corners of Chu Heng's mouth suddenly showed a cold smile.

For ordinary people, a hundred years may be a lifetime.

But for the alien spirits that often take thousands of years to mature, a hundred years is really not a long time, and at this time, the thunder spirit may still be in the transformation period.

Before this, there were people from the Cloud Thunder Sect who regularly fed Lei Ling, and Lei Ling might grow faster.

But the Cloud Thunder Sect was destroyed, and no one fed the Thunder Spirit, so the growth rate of the Thunder Spirit naturally slowed down.

This is also the reason why Lei Ling will make a move on Ouyang Xingchen, this is an instinct, the instinct to eat.

Chu Heng couldn't help but feel a little funny, Ouyang Xingchen thought that his luck was against the sky, but in fact, he almost returned to the netherworld.

However, Chu Heng will not point it out.

Chu Heng immediately closed his eyes again, his body entered a state of suspended animation, and he began to wait for Lei Ling to take the initiative to come to the door.

The so-called state of suspended animation is to adjust all the skills of one's body to the minimum, including breathing, heartbeat, and blood flow rate.

Chu Heng didn't know if Lei Ling was conscious now, but according to Ouyang Xingchen's words, and Lei Ling hadn't made a move after he had come in for so long before, obviously Lei Ling was also waiting for a suitable opportunity.

And this opportunity is that Chu Heng lost consciousness.

As Chu Heng entered the state of suspended animation, the entire bottom layer of the Thunder Pool suddenly became quiet.

Although the thunder is violent, because this is the thunder pool, these thunders have also become quiet.

Although all the functions of his body were adjusted to the minimum, Chu Heng's consciousness was extremely vigilant.

Lei Ling didn't appear at the first time, and Chu Heng was not in a hurry, this time was a time when Lei Ling was more patient.

Only after Lei Ling thought that Chu Heng really did not pose a threat to it, he would probably get him in.

An hour passed, and Lei Ling did not move.

Two hours passed, and Lei Ling did not move.

Half a day passed, but Lei Ling still didn't move.

After a day passed, Chu Heng clearly felt that the thunder in the entire thunder pool began to become unusual.

An aura of destruction and domineering began to fill the entire bottom of the thunder pool, causing the thunder at the bottom of the entire thunder pool to turn black.

Chu Heng didn't know where this aura came from, but it was real.

Not long after, Chu Heng felt as if something was wrapped around his body.

From this thing wrapped around his body, Chu Heng could clearly feel a craving, a desire for food, exactly the same as what Ouyang Xingchen said before.

Perhaps after perceiving that Chu Heng really didn't make any movement, these thunder tentacles wrapped around Chu Heng's body began to slowly retreat.

At the same time, a huge thunder vortex appeared from the thunder pool, like a huge mouth, engulfing Chu Heng entirely.

Chu Heng felt as if he had experienced a spatial teleportation.

When he opened his eyes, Chu Heng was in a black space.

In the entire black space, it was filled with incomparably violent thunder energy, and black thunder arcs were swimming everywhere, and the rumbling loud sound was deafening.

Chu Heng's body was wrapped with thunder tentacles that were completely condensed from black thunder, and in front of him was a thunder lake completely composed of black thunder.

In the middle of the Thunder Lake, there is a black Thunder Dragon.

This thunder dragon is ten zhang long, black thunder appears all over the body, the hideous dragon head is full of majesty, the two blood moon-like eyes are extremely shocking, the palm-sized dragon scales emit black thunder, and the five vigorous and powerful claws are even more flickering with a faint cold light.

However, the brontosaurus was firmly bound by five thick iron chains, one through its head, one through its backbone, and three through its left and right and fifth dragon claws.

Chu Heng shattered the thunder tentacles on his body and looked at the black thunder dragon in front of him.

Even from a long distance, Chu Heng could still feel a destructive energy and aura from the black thunder dragon's body.

This black thunder dragon is the thunder spirit that Chu Heng has been looking for.

In just a hundred years, this thunder spirit has successfully transformed.

Chu Heng could feel that although the thunder dragon had successfully transformed into a form, it had only been born with an extremely shallow consciousness.

This consciousness has just been born, just like a baby has just been born, and it has no capacity for self-judgment at all.

"The transformation was successful, what kind of thunder is this?" Looking at the thunder dragon in front of him, Ouyang Xingchen said in horror.

"Don't you know what kind of thunder this is?" Chu Heng said.

"Black Ray, I don't know. Ouyang Xingchen shook his head, he only knew that this was a thunder spirit, but he didn't know what thunder it was: "In the Heaven and Earth Alien Spirit Record, it seems that this kind of thunder spirit has not been recorded. ”

"Chaos Heavenly Thunder was born in the chaotic space and grew up in thousands of thunder sources. Chu Heng said: "There should have been another kind of thunder spirit here, but that thunder spirit was devoured by the Chaos Heavenly Thunder and became the nourishment for the evolution of the Chaos Heavenly Thunder. ”

"Chaos Heavenly Thunder, you say this black thunder is Chaos Heavenly Thunder?" Ouyang Xingchen said in shock.

The Chaos Heavenly Thunder let out an extremely loud dragon roar, and the ten-zhang long body stood up, looking at Chu Heng with blood-moon-like eyes, and black thunder arcs appeared on his body, ready to attack at any time!

Although the Chaos Heavenly Thunder does not yet have Xingchen's own consciousness, it also has a eating instinct, and it is in the instinct at this moment.

"How are you going to refine the Chaos Thunder Spirit?" Seeing that the Chaos Heavenly Thunder had already gotten up, Ouyang Xingchen couldn't help but ask a little nervously.

"Just look at it. A mysterious smile appeared at the corner of Chu Heng's mouth, and he took the lead towards Chaos Heavenly Thunder before the Chaos Heavenly Thunder attacked.

The thunder dragon transformed by the Chaos Heavenly Thunder slammed into the thunder lake, setting off a terrifying and violent black thunder tide, containing supreme power.

The Nether Wings behind Chu Heng shook suddenly, soaring into the sky and turning over the black thunder tide.

Then, Chu Heng's body flipped in the air, and the true qi in his body exploded instantly, separating countless afterimages, and continued to blast towards the thunder dragon.

The thunder dragon roared angrily, raised its huge dragon head, and opened its mouth to spit out a black thunderbolt.

The black thunder was extremely fast, piercing through the space in an instant, and accurately captured Chu Heng's true body among the countless afterimages.

"Breaking the Sky Ruler!" Chu Heng let out a low snort, and the lightning in his hand condensed into a golden ruler, which was shot out in an instant, turning into a golden streamer that accurately hit the black thunder.

With a loud bang, the Sky Breaker and the black thunder collided violently, triggering a strong and ferocious energy explosion.

Chu Heng operated the Great Sun Immortal Body, holding up a golden film of light on his body, and at the same time protecting his body with Netherworld Wings, and rushed into the energy storm strongly.

After a while, Chu Heng rushed out violently, killing the sky above the black dragon's head, and energy chains burst out from Chu Heng's body.

These energy chains were all condensed from the true qi in Chu Heng's body, and they were full of various energy runes, which had a natural suppressive effect on alien spirits.

The energy chain entered the black dragon's body, deeply locking the black dragon's flesh and skin.

Then the runes above lit up, and an extremely powerful devouring power came out from above, and it began to frantically absorb the energy of the Chaos Heavenly Thunder.

Chu Heng's hands kept changing, and he made special seals one after another, and these seals acted on the black dragon's body through chains, and began to seal the black dragon heavily.

Streams of black thunder poured into Chu Heng's body along the energy chain, operating the Primal Five Spiritual Techniques, frantically refining and absorbing these black thunders.

The thunder dragon roared angrily, and although it had not yet given birth to consciousness, it also felt a strong crisis.

The ten-zhang long dragon's body began to struggle violently, but it was locked by five iron chains, and it couldn't break free at all.

A terrifying black thunder tide boiled on the thunder dragon's body, like thousands of troops, and like a terrifying black curtain, bursting towards Chu Heng.

Chu Heng's hands kept changing, and a small black beast appeared in his hand.

The small beast's whole body was covered with black scales, its head was as big as a bucket, but its body was small, with only two claws, but it shimmered with an incomparably sharp cold light.

The Spirit Swallowing Beast roared, opened its mouth bigger than its head, and swallowed it towards the black thunder tide, swallowing it all.

In an instant, Chu Heng felt an even more turbulent and violent force surging into his body, and then he was quickly transformed into majestic energy by the Primal Five Spirit Technique, refining his body.

After swallowing the black thunder tide in one gulp, the Spirit Devouring Beast did not stop there, and its small body expanded rapidly.

In the blink of an eye, the Spirit Devouring Beast grew into a ten-meter-long giant beast, and then bit down towards the Thunder Dragon.

The sharp teeth of the Spirit Devouring Beast, and the terrifying bite force easily penetrated the dragon scales of the Thunder Dragon, biting the Thunder Dragon tightly.

At the same time, a terrifying and powerful suction force came out of the mouth of the Spirit Devouring Beast, seizing the power of the Chaos Heavenly Thunder in a predatory absorption method.

In an instant, an incomparably violent and terrifying energy poured out from the thunder dragon derived from the Chaos Heavenly Thunder, as if a river had burst its embankment, and the spirit devouring beast was used as a medium to rush into Chu Heng's body.

Subsequently, this incomparably violent and terrifying energy was quickly refined into pure energy by the Primal Five Spirit Techniques, and rushed into Chu Heng's limbs and hundreds of remains.

Feeling the crisis of life and death, Chaos Heavenly Thunder let out a monstrous roar, and the black thunder on his body completely rioted, and the terrifying power almost shattered the entire world.

The dragon's body was struggling violently, driving the five chains to make a loud noise.

At this moment, a large number of runes suddenly lit up on the five iron chains that locked the Chaos Heavenly Thunder, and an incomparably powerful force poured out from the five iron chains, and the black thunder tide that surged out of the Chaos Heavenly Thunder instantly pressed back.

Seeing this scene, Chu Heng suddenly showed a look of surprise, frantically running the Taichu Five Spirit Technique, frantically devouring the power of the Chaos Heavenly Thunder.

With a loud bang, an extremely powerful energy poured out of Chu Heng's body, and Xiu Wei actually broke through to the Jindan Realm Triple at this moment.

However, there was no tendency to stop, and he continued to move towards the Jindan Realm Quadruple.

The Chaos Heavenly Thunder struggled violently, the ten-zhang long dragon body writhed wildly, and the black thunder arc on its body 'crackled'.

Its five vigorous and powerful claws slapped against the Thunder Lake, constantly setting off a terrifying black thunder tide.

The whole world lit up with pieces of ancient runes, and a wave of energy like heavenly power pressed towards the Chaos Heavenly Thunder, as if there was a pair of invisible big hands pressing the Chaos Heavenly Thunder into the thunder lake.

The thunder dragon kept roaring, but he couldn't break free from the blockade of the five iron chains, and could only passively accept that Chu Heng was constantly absorbing power from the dragon.
