Boom! Boom!

In the huge ruined ancient city, the two figures clashed like lightning in mid-air, and in just a few moments, they collided thousands of times.

Every time there was a collision, an extremely terrifying impact of source qi erupted, leveling countless dilapidated buildings below.

The confrontation of that level was just the spread of some aftermaths, and it was able to severely damage some Tianyang Realm powerhouses with a source qi foundation of less than three and a half billion, which showed how fierce and fierce the battle between the two was.

Bang!

Another hard regret, the source qi exploded, and Su Lei's figure appeared in mid-air, his face was expressionless, and his eyes were extremely cold.

His source qi is as much as 100 million stronger than Zhou Yuan's, and the source qi he cultivates is also the eighth-rank Jinxiao Thunder Tribulation Qi, which is known for its destructive power, strong and fierce, but even so, in the previous confrontation, he did not achieve too many advantages.

"The quality of the source qi cultivated by this guy is probably even better than that of my Jinxiao Thunder Tribulation Qi..."This kind of discovery made De Su Lei a little frightened, the source qi he cultivated, even in the eighth grade, should be regarded as superior.

This level of source qi must be the highest level in those five days, and as for the real nine-rank source qi, let alone those five days, even in the Holy Clan, it is extremely rare.

Therefore, when he noticed that the platinum source qi that Zhou Yuan had cultivated was actually so strong, he couldn't help but feel stunned.

Although this is not the source qi of the ninth grade, it is definitely the pinnacle of the eight!

Moreover, the mottled black pen in Zhou Yuan's hand should also be regarded as touching the threshold of the holy object, otherwise, it would be impossible to collide with his red thunder stick without falling behind, you must know that his red thunder stick, but the Holy Ancestor Heaven sage personally refined it for him, if the time and chance come, it may not be able to step into the real holy object level.

It was precisely because of the level of the source qi that the other party had cultivated and the mottled black pen that he was able to stop his previous attack.

"In that case..."

Su Lei's eyes were cold, and the next moment, his hands suddenly sealed.

I saw that there was a golden light erupting from its heavenly spirit cover, and the golden light directly converged in the sky above it, and it turned into a golden thundercloud, and in the thundercloud, the golden thunder meandered and flowed, releasing a terrifying power that shook the heavens and the earth.

"Golden Thunder Technique!"

With a loud shout from Su Lei, there was suddenly a Dao Dao golden thunder in the thundercloud, which fell down and slashed fiercely on Su Lei's body.

However, the golden thunder did not cause him the slightest damage, on the contrary, the source qi in his body was directly climbing at an extremely alarming speed under the splitting of that lightning strike.

In just a few breaths, the source qi of that thunder has reached the level of 4.8 billion!

That's an increase of nearly 400 million!

Su Lei stood in the void, and the golden thunder around him was constantly flickering, making him look like a god of thunder, and his power was amazing.

Xu Lei looked down at Zhou Yuan below, and his expression was faintly proud: "Zhou Yuan, my secret method, looking at the Tianyang territory of my holy clan, is considered to be the top, you can force me to a secret method to defeat you, it can be regarded as your ability." ”

When the strength reaches the point of them, it is almost the pinnacle of the Tianyang Realm, so to this extent, the general secret method has almost no effect, but this Su Lei can still skyrocket up to 400 million source qi foundation, this kind of secret method is indeed quite powerful.

"The secret method that can improve the essence of 400 million source qi is really amazing. ”

Zhou Yuan also exclaimed, and immediately on the mottled body of the Tianyuan pen in his hand, an ancient and obscure rune suddenly brightened, and the source qi between heaven and earth roared wildly.

"Promotion!"

At this moment, Zhou Yuan's source qi was also skyrocketing wildly!

Directly from 4.3 billion to 4.8 billion!

The improvement of 500 million source gas heritage!

Before Zhou Yuan had not broken through to the late stage of the Tianyang Realm, if he urged the "promotion", he would almost be able to provide him with 700 million or more source qi foundation improvements, but as Na Sulei said, as they stepped into the late stage of the Tianyang Realm, they also gradually reached the peak of this realm, and at that time, if they wanted to improve again, the difficulty was naturally much higher than before.

Therefore, Zhou Yuan's "promotion" has also been weakened a little and has become 500 million.

But even so, the pride on Nasulei's face suddenly froze.

"The improvement of 500 million foundations?!How is it possible?" There was a look of disbelief in Su Lei's eyes, what kind of secret method is this, how can it achieve such an improvement?

His gaze stopped at the Tianyuan pen in Zhou Yuan's hand, and from there, he faintly felt a trace of coercion.

That kind of coercion... Some of them are like real holy relics!

However, compared to the holy relics, the power is much weaker.

"Is it a former holy relic?" Su Lei's vision was also extremely wide, and he quickly guessed the answer, and his face immediately sank slightly.

And when Su Lei was shocked in his heart, Zhou Yuan looked at him with a hint of banter on the corner of his mouth: "Do you think this is the end?"

He squatted slightly, his palm slapped to the ground, and between his palms, a holy pattern emerged.

"Earth Holy Pattern!"

Rumble!

The earth shook, and ripples visible to the naked eye spread.

The next moment, in the depths of the earth, an incomparably thick source qi rushed into the body brutally.

Under Zhou Yuan's skin, there seemed to be small snakes scurrying around, trying to break out of his body, but in the end he was firmly restrained by the tough body.

And Zhou Yuan's source qi was once again increasing at a steady rate under Na Su Lei's shocked gaze.

Billion!

Another 200 million increase!

"You!" Facing Zhou Yuan, who was threatening and terrifying at this time, even Su Lei was a little speechless, and his round eyes revealed the shock in his heart.

At their level, the effect of ordinary secret methods is already not great, but this Zhou Yuan actually has two kinds of them, and they are two that do not conflict with each other?

Zhou Yuan raised his head, he looked at Su Lei, who was a little shocked, and the banter on the corner of his mouth became even richer: "I'm sorry, you can call me... King of the Mystic!"

Rumble!

As soon as his voice fell, before Nasu Lei could respond, his figure suddenly burst out of the air.

The sonic boom rang out, as if there were invisible ripples.

Zhou Yuan's speed was originally inferior to Su Lei, but now under the forcible urging of this five billion source qi, the explosion in that moment actually surpassed Xu Lei!

So when Su Lei reacted, Zhou Yuan had already appeared in front of him as if he was teleporting.

Bang!

"Ten thousand whales!"

The ancient whale moaned echoed through the heavens and the earth, and the mottled pen body seemed to turn into the giant pillar of the sky, wrapped in indescribable power, and smashed into the thunder.

Su Lei is not an ordinary person, at the critical moment, a long roar, there is a thunder on the red gold stick, and it is also running with all its strength, and there are thousands of golden thunder blooming behind him, majestic and domineering, and he directly meets it.

Clang!

The sound of gold and iron exploded, and the void was directly torn apart.

Bang!

But then, a figure flew out upside down in embarrassment, and its body smashed into the ruined ancient city, directly tearing out a deep crack of thousands of feet, and I don't know how many buildings were shaken into powder along the way.

When the man rushed out of the ruins again, he saw his face clearly, it was Sulei!

At this time, his face was a little gloomy, and he was completely suppressed by Zhou Yuan in the previous confrontation.

"Okay—" His eyes were cold.

Rumble!

However, before he could finish a sentence, the void in front of him exploded again, and Zhou Yuan's figure stepped out of the air like a wild beast, and the terrifying source qi offensive blasted over like a torrential rain in front of him.

In the face of Zhou Yuan's aggressiveness, Na Su Lei also roared angrily, and the thunder light on his body was entangled, unable to show weakness, and he greeted him with all his might.

Thundered!

In the sky above the ruined ancient city, two figures frantically attacked each other, turning into countless afterimages.

The spread of each aftermath will tear apart the void and sweep away vast areas of ruins.

However, no matter how unwilling Na Sulei was to admit it, in such a hard encounter with the source qi, he really fell into the disadvantage.

Zhou Yuan's five billion source qi background put him at a disadvantage in all aspects.

Clang!

So, in that hard regret again, Su Lei flew out upside down again, but this time, he didn't step forward recklessly, because he knew that it was meaningless, and if he continued to rely on the source qi to fight, it would only make his injuries worse.

Call.

Su Lei took a deep breath and crossed his palms across the void in front of him, crossing the mysterious trajectory and causing the starry sky to shake.

Boom!

Behind him, the void trembled, the golden thunder roared wildly, and countless thunderbolts intertwined, as if turning into an ancient thunder pattern, in that pattern, there seemed to be a giant roaring in the sky, like a thunder god.

An extremely terrifying aura of danger enveloped the heavens and the earth.

Zhou Yuan's figure also stopped, his eyes slightly solemn.

"This trick..."

And when Zhou Yuan was tense, the thunder contained a thick murderous sound in the coldness, which was already wrapped in thunder, echoing the heavens and the earth.

"Holy Source Technique, Nine Palace Thunder!"

Zhou Yuan's pupils shrank suddenly.

Sure enough... Holy Source Technique!

It seems that this guy was really set on fire.
