A bright figure walked out from the mural.

In the left eye of this figure, there is a vortex of lightning, with hundreds of millions of lightning intertwined, and infinite lightning runes flying.

In the right eye, there is a golden vortex, a series of mysterious golden chains, extending from the golden vortex, reaching into the depths of time and space.

"Lei Zu!"

Almost instantly, Chu Zhou confirmed that the figure in front of him was Lei Zu.

"This... is Lei Zu?"

Sister Dao also concluded that the bright figure in front of her was Lei Zu.

Staring at Lei Zu, she clearly noticed that the 'Thunder Punishment Body' that she had just successfully cast was resonating with the other party.

seem to have their common origin.

A streak of golden lightning uncontrollably drilled out of her body, covering the surface of her body.

"I am Lei Zu, you need to pass the test I set before you can inherit my inheritance!"

The bright figure spoke suddenly.

Hong Zhong Dalu's voice resounded through the void.

It was a supreme oppressive force, oppressing Chu Zhou and Sister Dao.

this moment.

Both Chu Zhou and Sister Dao had the illusion that a vast universe was suppressing them, making them feel unimaginable pressure.

So strong!

Chu Zhou and Sister Dao both showed a trace of seriousness in their eyes.

Lei Zu in front of him is obviously just a spiritual imprint left by Lei Zu.

But even so, it is still unimaginably powerful.

Chu Zhou was thinking about what Lei Zu said just now.

Lei Zu mentioned 'you' just now, not 'you'.

Does this mean that both he and Sister Dao belong to the people being assessed?

"Could it be that the reason why Lei Zu set up the three-level assessment requires that every Tianjiao must have a guardian... Is this the purpose?"

"He's not just looking for one inheritor, but two?"

Thinking of this in Chu Zhou's heart, he couldn't help being slightly pleasantly surprised.

Lei Zu is suspected to be a holy emperor.

His inheritance is of unlimited value.

If he can also obtain Lei Zu's inheritance, it will undoubtedly be a great thing.

Just as Chu Zhou was guessing Lei Zu's purpose, Lei Zu's figure suddenly split into two.

A thunder ancestor, the surface of the body is intertwined with lightning.

Another Leizu has golden causal chains wrapped around his body.

Shua!

Lei Zu's lightning avatar suddenly grabbed Sister Dao from the air, dragged Sister Dao into a world of thunder, and attracted countless thunder and lightning to attack Sister Dao.

Sister Dao reacted quickly, and immediately summoned the Thunder God suit, and urged the ancient divine script of the word 'electricity', holding the Thunder God Sword in her hand, to fight against Lei Zu's thunder and lightning clone.

"Sister Dao!"

Chu Zhou was taken aback when he saw Sister Dao was taken away suddenly, and wanted to rush over to rescue Sister Dao immediately.

Sister Dao is just a world lord, so how could she be the opponent of Lei Zu's thunder and lightning avatar?

But he soon discovered that after Lei Zu's lightning avatar pulled Sister Dao into a world of thunder, its own energy fluctuations quickly weakened to the level of the world master.

He immediately understood that Lei Zu's thunder and lightning avatar suppressed his own strength to the same level as Sister Dao, and then assessed Sister Dao.

This puts him at ease.

No longer in a hurry to save Sister Dao.

At this time, Lei Zu's causal avatar also appeared in front of him in a flash.

This causal avatar is surrounded by mysterious causal chains, and there are countless causal lines that are looming, extending from other bodies and extending into the depths of endless time and space.

This causal avatar has five fingers, and there are countless causal lines flying out like rays, covering the surrounding void.

The next moment, Chu Zhou found himself in a world covered with countless golden causal lines.

Suddenly, Chu Zhou found that his heart had been penetrated by a causal line at some point.

"not good!"

His scalp was numb, and he immediately felt a little bit of crisis.

At this moment, he noticed that Lei Zu's causal avatar had a pure golden spear in his hand.

Lei Zu's causal avatar glanced at him lightly, and suddenly threw the pure gold spear out.

In an instant, the pure gold spear, like a golden bolt of lightning, pierced through the universe and pierced towards Chu Zhou's heart.

Chu Zhou felt the energy fluctuation far surpassing that of a high-ranking prince from the pure gold spear.

"The Book of Ten Thousand Laws!"

Chu Zhou sacrificed the 'Book of Ten Thousand Laws' without hesitation, let it stand in front of him, and aroused the power of the 'Book of Ten Thousand Laws'.

However, a scene that shocked him appeared.

The pure gold spear, like a golden lightning, became transparent when it approached the 'Book of Ten Thousand Laws', penetrating the 'Book of Ten Thousand Laws' like a phantom.

Then, there was a sharp pain in his heart.

He looked down, and suddenly found that his heart had been pierced.

A fist-sized blood hole appeared in his heart.

Rolling blood, gushing out of the blood hole like a fountain.

He also saw the pure gold spear piercing through his body through his divine sense, and it was flying towards the distance.

The heart was pierced. To Chu Zhou, it was not a serious injury.

But he frowned.

"What's going on here? The 'Book of Ten Thousand Laws' is powerful enough, why can't it stop the opponent's spear?"

He was thinking seriously, and a flash of light suddenly flashed in his mind.

"It's cause and effect! Lei Zu's causal avatar, when he used the pure gold spear to attack me, changed the cause and effect of this attack. He first confirmed the result of 'must hit', and then executed the cause of throwing the spear. So, as long as he Throw a pure gold spear at me, and I will definitely be shot in the heart by him. No matter what method I use, I can't stop his attack."

"Unless, I can modify the cause and effect he set, or make the cause and effect he set untenable."

During these days, he has worked hard to understand the law of cause and effect, and he is not ignorant of the way of cause and effect.

Especially after researching and deducing the 'cause and effect thunder net' of the ancestor of the Lei clan, he already has a deep understanding of the way of cause and effect.

Therefore, he quickly deduced the reason why he couldn't resist and dodge Lei Zu's shot just now.

At this time, Lei Zu indifferently threw a pure gold spear at Chu Zhou again.

With a thought, Chu Zhou teleported tens of thousands of meters away.

However, he still couldn't dodge the pure gold spear.

The pure gold spear also teleported, and with a puff, it pierced through his heart again, causing another stream of blood.

"It seems that my inference is correct."

After passing this test, Chu Zhou confirmed that his deduction was correct.

"If I want to avoid the pure gold spear, unless I can erase the causal line connected to me by Lei Zu, or prevent Lei Zu from throwing the spear..."

or, there are other ways.

Chu Zhou didn't care about his injuries.

He was pierced through the heart twice in a row. Although the injury was not serious, it was still a thousand miles away from killing him.

At this moment, Lei Zu, standing opposite him, suddenly waved his hand, and in an instant, densely packed pure gold spears appeared in the void.

The quantity is at least one hundred thousand or more.

Chu Zhou: "..." He retracted his previous thoughts.

A pure gold spear, pierced through the heart, could not kill him.

But if tens of thousands of pure gold spears penetrated his vitals and even his soul at the same time, it could really threaten his life.

Even if you can't really kill him.

It would also be extremely traumatic for him.

He mobilized his divine sense to scan his body, and suddenly found that, at some point, countless golden threads of cause and effect had been connected to his body.

Among them, many lines of cause and effect are connected to the internal organs and the head.

He even 'saw' dozens of lines of cause and effect, connected to his soul.

These lines of cause and effect are invisible and intangible. Even if Chu Zhou finds that they are connected to himself, he cannot erase them and has no choice.

"The law of cause and effect is indeed one of the three taboo laws. It is the same as the law of space and time, and far more terrifying than ordinary laws."

Chu Zhou sighed in his heart, raised his head and looked at Lei Zu on the opposite side, and when he saw densely packed pure gold spears floating around him, the corners of his mouth could not help but twitch slightly.

What the hell.

Lei Zu's test is a bit abnormal.

Is this trying to kill him?

At this time, Lei Zu suddenly waved his hand.

"Woooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo-"

In an instant, a handful of pure gold spears pierced the void like dense lightning, and shot towards Chu Zhou with piercing screams.

If Chu Zhou is an ordinary prince.

There is probably only one end: being impaled into a hedgehog in an instant by the densely packed pure gold spears with the effect of 'must hit'.

"The law of cause and effect is an eye-opener."

Chu Zhou looked calm, and suddenly smiled faintly:

"It's just that, although the law of cause and effect is strong, the law of time and space is not weak!"

"Time and space reverse flow!"

He made a thought, his consciousness matched the law of time and space in the dark, and he snapped his fingers with his right hand.

In an instant, a majestic power of space-time laws suddenly descended on this void.

The densely packed pure gold spears flying towards Chu Zhou stopped suddenly, and then flew back along the original trajectory.

"Huh? The law of space and time?"

Lei Zu's causal avatar, in the indifferent eyes, there is a flash of surprise at this moment.

At this time, Chu Zhou stepped on the long river of time and space, and came to Lei Zu's causal avatar like a ghost.

"Time and space imprisoned!"

Chu Zhou's body was filled with pale light, and the power of the law of time and space swept out from him, and he directly imprisoned the time and space where Lei Zu's causal clone was located.

After that, he urged the 'Book of Ten Thousand Laws' to suppress the opponent.

Boom!

The 'Book of Ten Thousand Laws' hit Lei Zu fiercely.

but.

At the moment when the "Book of Ten Thousand Laws" hit Lei Zu, golden lines of cause and effect suddenly appeared on his body, and those lines of cause and effect were all connected to Chu Zhou's body.

In an instant, Lei Zu's 'Book of Ten Thousand Laws', which was supposed to severely damage Lei Zu, flew backwards and blasted towards Chu Zhou, the master.

"Reverse cause and effect?"

Chu Zhou's complexion changed slightly, and he used 'Time and Space Reverse Current' again.

The 'Book of Ten Thousand Laws' immediately flew backwards again, following the original trajectory, and continued to bombard the Thunder Clan.

The lines of cause and effect on Lei Zu's body also oscillated wildly. Whenever the "Book of Ten Thousand Laws" hit him, they would fly backwards and attack Chu Zhou, the master.

Suddenly, the two fell into a state of 'extreme pulling'.

Both sides are frequently using the laws of time and space and the law of cause and effect to change the attack target of the 'Book of Ten Thousand Laws'.

In this battle, Chu Zhou experienced the horror and power of the law of cause and effect.

Facing Lei Zu who can easily modify the cause and effect or specify a certain cause and effect effect, it is too difficult for Chu Zhou to suppress the opponent smoothly.

Just relying on the laws of space and time, he couldn't defeat Lei Zu, a causal avatar.

As a last resort, he used the law of chaos, the law of yin and yang, the law of five elements, the law of reincarnation and so on.

Relying on the Five Great Laws, he finally gradually put Lei Zu at a disadvantage.

About six hours later, Chu Zhou fully mobilized the power of the five laws, and urged the "Book of Ten Thousand Laws", with a bang, smashing Lei Zu's causal avatar.

"Finally won."

Chu Zhou panted slightly.

Lei Zu's causal avatar is really too strong. If he didn't master the five laws at the same time, it would be basically impossible for him to suppress the opponent within six hours.

"I don't know how Sister Dao is doing?"

He hurriedly looked towards the Thunder World where Sister Dao was.

Soon, he saw Sister Dao, who was covered in blood and had many charred marks on her body, kneeling on one knee in the void.

Lei Zu's Thunderbolt avatar hovered indifferently above Sister Dao.

"Did Sister Dao fail? Didn't pass the test?"

Chu Zhou couldn't help feeling tense.

Sister Dao did not hesitate to break through this level. It would be a pity if she failed here and did not obtain the inheritance of Lei Zu.

"Failed?"

Sister Dao looked up at Lei Zu, who was surrounded by thunder and lightning, and let the blood flow down her cheeks. A trace of unwillingness flashed in her sharp eyes.

She did her best.

The power that reached the level of the venerable burst out.

But the Thunder Ancestor avatar in front of him is really too strong.

Even if she tried her best, she was still no match for the opponent.

"No, I can't lose here."

Sister Dao gritted her teeth, ready to stand up and fight again.

She knew the preciousness of this opportunity.

This is related to the inheritance of a holy emperor.

If she misses this opportunity, she probably won't find such a good opportunity in the future.

Therefore, she cannot be defeated.

However, Sister Dao just stood up and before she could make a move, Lei Zu's thunder and lightning avatar spoke first.

"Junior, you have passed the assessment, and you can get my Thunder Punishment inheritance!"

After finishing speaking, Lei Zu's thunderbolt avatar disappeared.

"Teacher, how are you doing?"

Chu Zhou teleported to Sister Dao's side, supported her, and activated a majestic and pure force to cover her body and heal her.

"I'm fine!"

Sister Dao smiled faintly.

Boom!

at this time.

In the void, the huge ancient mural suddenly shattered.

Two groups of extremely vast and majestic light groups, like two suns, flew out of the shattered mural.

One of the **** of light is like a huge thunder sun, intertwined with infinite thunder and lightning.

Another group of light is like a huge golden sun, with countless golden chains of cause and effect wrapped around its surface.

Two groups of extremely bright rays of light pierced through the void and merged into the bodies of Sister Dao and Chu Zhou respectively.

In an instant, both Chu Zhou and Sister Dao obtained an extremely majestic and pure life energy.

At the same time, a large number of laws and practice memories also appeared in their minds.
