"Die!"

When Xia Yun just stood up, Shi Zhuang appeared in front of him like a meteor and roared confidently, as if only in this way could he vent his grievances just now.

He was a high-level earth immortal, how could he lose to a mere mortal like Xia Yun.

He was really worried.

Xia Yun saw Shi Zhuang's appearance, squinted his eyes, Shi Zhuang at this moment, his whole body was covered with steel, giving people an indescribable sharp feeling.

"Steel Immortal Aura?"

Xia Yun was a little surprised in his heart, although his cultivation time was not too long, but it was also several decades, and in the land of the four directions, he really had never seen anyone who cultivated steel aura, except for spirit beasts.

The Iron Holy Dragon is a demon beast that uses steel aura.

In a sense, Xia Yun is not a stranger to steel aura, but he has never fought against a strong person who cultivates steel aura.

Although the steel aura is far less mysterious than the ethereal aura and the time aura, this uncommon aura still makes Xia Yun feel a little jealous, but it is more curious.

"Boom!"

As soon as his mind moved, Xia Yun turned into a thunderous body, and the terrifying thunder of chaos rose into the sky.

At this moment, Xia Yun seemed to be descending as a thunder god.

When Shi Zhuang saw this scene, he didn't have any timidity, he believed that Xia Yun must be pretending to be a ghost, this was just the other party's last struggle, such a powerful thunder spirit origin would only be a flash in the pan, without any threat.

"Thunder Strike!"

Without hesitation, Shi Zhuang threw a punch at Xia Yun, and terrifying thunder light emerged from that huge fist.

"Thunder rules?"

As soon as Xia Yun saw the thunder light, his heart was even more surprised, although Shi Zhuang had already cultivated the origin of the steel spirit, he had also cultivated the rules of thunder.

Although the Origin Power, under normal circumstances, can only be cultivated in one kind, there is no such restriction on the Rule Power.

In other words, it's not that you can't cultivate a variety of origin powers, but you don't have that kind of comprehension and physical endurance.

Only at the level of the Immortal Emperor can he cultivate the two origin powers.

Even Xia Yun has four origin powers, but three of them don't really belong to him, and others have lent them to him.

It was precisely because it was borrowed that Xia Yun could not better exert the power of the Thunder Spirit Origin.

Otherwise, Xia Yun's current combat power is at least at the level of a heavenly immortal, how can he be as long as Shi Zhuang's inkblot.

Facing the immortal method cast by Shi Zhuang, Xia Yun did not have any contempt, even if it was only a true spirit immortal method, but when it burst out from the hands of the earth immortals, the power was not at the level of true immortals.

"Thunder extinguished!"

A punch blasted out, the thunder light bloomed, and Xia Yun's thunder body immediately exploded, and the fist instantly exploded, like a small mountain, smashing towards Shi Zhuang.

"Boom!"

Two fists, one big and one small, collided with each other.

Although Shi Zhuang's fist was small, it was as powerful as a bamboo, and in an instant, it pierced Xia Yun's thunder fist, which was bound to penetrate the opponent's body.

However......

The moment Xia Yun's Thunder Fist appeared behind Shi Zhuang, Shi Zhuang stopped, his eyes widened, and he stared at the Thunder Fist that was blocking his fist in disbelief.

Between the two fists, there was a burst of lightning.

At this moment, Shi Zhuang realized that the huge Thunder Fist just now was just a trick, and Xia Yun's real killing move was the small Thunder Fist hidden in the huge Thunder Fist.

"No!"

Shi Zhuang screamed miserably.

The moment his steel fist hit Xia Yun's thunder fist, it began to melt, like lava, turning into molten iron and finally evaporating.

Soon, the fists were gone, the arms were gone, and even the body was gone.

Endless thunder devoured Shi Zhuang in an instant.

In the end, there was only a scorched black left on the ground, and it was two footprints that proved the existence of Shi Zhuang.

"Whew!"

Xia Yun exhaled heavily, and then returned to his original state, but his face was extremely pale, giving people an indescribable sickness.

"Sure enough......"

Xia Yun glanced at his fist, as he passed the Spirit Tribulation, his soul became stronger, especially the fusion of martial spirits and demon spirits, his spiritual strength was terrifyingly improved, and his control over the origin of the thunder spirit had a qualitative change.

Pity......

"It's still not enough!"

Xia Yun sighed in his heart.

He estimated that he could still only exert less than one percent of the power of the Thunder Spirit's origin, or even less.

He knew that the origin of the thunder spirit that Xiao Hei gave him was extraordinary, and it was only as his cultivation increased and his knowledge increased, and he really realized that he was a bit of a frog at the bottom of the well.

The origin of the thunder spirit left to him by Xiao Hei can no longer be described as extraordinary, at least not so low.

What exactly?

Xia Yun didn't know, and he couldn't figure it out.

What's more, what Xiao Hei left him was not only the Thunder Spirit Origin, but also the Water Spirit Origin.

At this moment, Xia Yun somewhat understood why the origin of the water spirit was not complete.

Obviously, Xiao Hei hoped that Xia Yun would use the Thunder Spirit Origin to repair the Water Spirit Origin, and from this process, he would comprehend the true meaning of the Origin Power.

Xia Yun comprehended the Ethereal Origin, but he knew very well that his Ethereal Origin was only a prototype, and it was not even as good as the Water Spirit Origin.

He still has a long way to go.

However, his current focus will not be on the ethereal origin for the time being, after all, this process requires a lot of time to comprehend, explore and cultivate, and there is no way to rush it.

Otherwise, there would not be so few immortal emperors in this world.

Other Xia Yun didn't know, but there was one thing, he knew that the growth of the Immortal Emperor was calculated in the past thousand years, at least the existing nine Immortal Emperors, without exception, were all like this, but these nine people, without exception, had achieved high-level saint immortals within a hundred years.

These things were told to Xia Yun by Yan Xuexin, the former spirit of creation.

Although the Immortal Emperor is essentially a high-level Saint Immortal, the gap between them is as large as thousands of years, or even tens of millions of years.

After that, Xia Yun came to Lu Shan's side to help treat the other wounded.

Although Lu Shan wanted to refuse, Xia Yun ignored it.

At this moment, Lu Shan was not surprised by Xia Yun's strength, but the friendship of the other party.

Before I knew it, half a day had passed.

Lu Shan and the others had already come to a small valley, planning to rest for the night.

At this time, there were only 20 people left in the original 40 people, and 10 of them were unconscious, and only 5 people could really walk.

Lu Shan, is one of them.

In a sense, those who are in a coma are a burden to this trip.

Lu Shan knew this very well, and had to hesitate in his heart.

It stands to reason that Lu Shan should give up this trip to Black Snake Valley.

They stayed, and they couldn't help Xia Yun too much.

Xia Yun rejected Lu Shan's proposal.

As for the reason, only Xia Yun knew, and Lu Shan didn't ask after all.
