Boom! Boom!

In the huge ruined ancient city, two figures clashed like lightning in the air. In just a short moment, they collided thousands of times.

Every collision erupts with extremely terrifying source energy impact, razing countless broken buildings below to the ground.

That level of confrontation, just the diffusion of aftermath, can severely damage some powerful people in the Tianyang realm with a source energy foundation of less than 3.5 billion. This shows how fierce and fierce the two's fight is.

Bang!

Another hard regret, the source energy burst out, and Xu Lei's figure appeared in the air. His face was expressionless, and his eyes looked particularly cold and fierce.

His source energy foundation is as high as 100 million stronger than Zhou Yuan, and the source energy he cultivates is also the Jinxiao Thunder Tribulation Qi, which is ranked eighth-grade. This source energy is known for its strong destructive power and is fierce and fierce, but even so, he did not gain much advantage in the previous confrontation.

"The quality of the source energy that this guy cultivates is probably even better than my Golden Sky Thunder Tribulation Aura..." This discovery made Xu Lei a little scared. The source energy he cultivated is considered to be of the best even among the eighth grade.

This level of source energy must be the top level in those five days. As for the real ninth-grade source energy, not to mention those five days, it is extremely rare even in the holy clan.

So when he realized that the platinum source energy that Zhou Yuan practiced was so strong, he couldn't help but feel shocked.

Although this is not the ninth-grade source energy, it is definitely the peak of the eighth-grade!

Moreover, the mottled black pen in Zhou Yuan's hand should have touched the threshold of the holy object. Otherwise, it would be impossible to fight with his Red Thunder Stick without falling behind. You should know that his Red Thunder Stick was personally refined by the saint of the Holy Ancestor Heaven. If the opportunity comes by time, he may not be able to enter the real level of the holy object.

It is precisely because of the level of the source energy that the opponent has cultivated and the mottled black pen that he can stop his previous offensive.

"Since that's the case..."

Xu Lei's eyes were cold, and the next moment, his hands suddenly formed seals.

I saw a golden light gushing out from the sky spirit cover. The golden light directly gathered above it and turned into a golden thunder cloud. In the thunder clouds, golden thunder meandered and flowed, releasing the power of terror and shaking the world.

"Golden Thunder Body Technique!"

With the loud shout of Xu Lei, golden thunder suddenly fell from the thunder clouds and slashed hard on Xu Lei's body.

However, the golden thunder did not cause any damage to him. Instead, the source energy in his body was directly rising at an extremely astonishing speed.

In just a few breaths, the source energy of the thunder reached the level of 4.8 billion!

It has increased by nearly 400 million!

The thunder stood in the void, and the golden thunder was constantly swirling and flickering, making him look like the god of thunder, with amazing pressure.

Xu Lei looked down at Zhou Yuan below, with a proud look on his face: "Zhou Yuan, my secret technique is top-notch in the Tianyang realm of my holy clan. It is also your ability to force me to defeat you with a secret technique."

When their strength reaches their level, it is almost the peak of the Tianyang Realm. So to this extent, ordinary secret techniques have almost no effect, but this Xu Lei can still soar to 400 million yuan in the source energy foundation. Such secret techniques are indeed quite powerful.

"The secret method that can actually improve the foundation of 400 million source energy is really amazing."

Zhou Yuan also exclaimed, and then an ancient and obscure rune suddenly became bright on the mottled pen in his hand, and the source energy between heaven and earth roared wildly.

“Promotion!”

At this moment, Zhou Yuan's source energy foundation also skyrocketed wildly!

It has directly stepped from 4.3 billion to 4.8 billion!

The improvement of the 500 million source energy foundation!

Before Zhou Yuan broke through to the late stage of the Tianyang Realm, if he activated the "promotion", he could almost provide him with 700 million or even more improvements in the source energy foundation. But as Nasu Lei said, as they entered the late stage of the Tianyang Realm, they gradually reached the peak of this realm. At that time, it was naturally much more difficult to improve at that time.

Therefore, Zhou Yuan's "promotion" was also weakened somewhat, becoming 500 million yuan.

But even so, the proud look on Xu Lei's face suddenly stagnated.

"A 500 million-dollar foundation improvement?! How is it possible?" Xu Lei's eyes were a little incredible. What secret method is this that can actually achieve such an improvement?

His eyes stopped at the Tianyuan pen in Zhou Yuan's hand, and from that, he felt a faint sense of pressure.

That kind of pressure...somewhat looks like a real holy thing!

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

"Is it a former holy object?" Xu Lei's vision was also very broad, and he quickly guessed the answer, and his face immediately darkened slightly.

When Xu Lei was shocked and suspicious, Zhou Yuan looked at him with a hint of joke on his lips: "Do you think this is over?"

He squatted slightly, slapped his palm towards the ground, and a holy pattern appeared in his palm.

"Earth Holy Pattern!"

boom!

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

The next moment, deep in the earth, an extremely heavy source energy rushed into the body ruthlessly.

Under Zhou Yuan's skin, there seemed to be small snakes rushing, trying to break out of their body, but in the end they were firmly bound into their body by their tough body.

Zhou Yuan's source energy once again increased at a stable speed in Nasu Lei's shocked gaze.

Five billion!

Another 200 million increase!

"You!" Facing Zhou Yuan, who was terrifyingly suppressed at this time, even Xu Lei was speechless, with his wide eyes showing a shock in his heart.

At their level, the effect of ordinary secret techniques is not great, but Zhou Yuan actually has two types of them? And they are two that are not conflicting with each other?

Zhou Yuan raised his head, and he looked at the shocked thunder, and the joke on the corner of his mouth became even stronger: "Sorry, you can call me... the King of Secret Techniques!"

boom!

As soon as his voice fell, his figure suddenly broke out of the air without waiting for the Thunder to respond.

The sound boom echoed, as if there were invisible ripples.

Zhou Yuan's speed was originally not as fast as that of Xu Lei, but now under the forced activation of the five billion source energy, the instant explosion actually surpassed Xu Lei!

So when Xu Lei reacted, Zhou Yuan had already appeared in front of him like a teleportation.

Boom!

"Ten thousand whales!"

The ancient whale chant echoed the world, and the mottled pen body seemed to turn into the giant pillar that held the sky, wrapped in an indescribable power and smashed hard at the thunder.

The thunder is not an ordinary person. In a critical moment, a long roar was heard, and there was a lightning light on the red gold stick. It also used all its strength, and behind it, there were thousands of golden thunders blooming, majestic and domineering, and directly met.

clang!

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

Bang!

But then, a figure flew backwards in a mess, and his body fell into the ruined ancient city, directly tearing a deep crack of thousands of feet apart, and there was no idea 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 the thunder!

At this time, his face was a little gloomy. After the previous encounter, he was completely suppressed by Zhou Yuan.

"Okay..." His eyes were cold.

boom!

However, before a word was finished, the void in front of him was shattered again, and Zhou Yuan's figure emerged like a wild beast, and the terrifying source energy attack rushed towards him like a rainstorm.

Faced with Zhou Yuan's aggressiveness, the thunder roared angrily, and the lightning was wrapped around his body, unable to show weakness, and he welcomed him with all his strength.

Rumble!

Over the ruined ancient city, two figures attacked each other wildly, turning into countless afterimages.

Every aftermath spread will tear the void and sweep away large areas of ruins.

However, no matter how reluctant Xu Lei refused to admit it, he was really at a disadvantage in such a head-on fight with the source energy.

Zhou Yuan's five billion source energy foundation made him at a disadvantage in all aspects.

clang!

So, in that hard regret, Xu Lei flew backwards again in a mess, but this time, he did not step forward recklessly because he knew that it was meaningless. If he continued to fight with the source energy foundation, his injury would only aggravate.

call.

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

Boom boom!

Behind him, the void trembled, the golden thunder roared wildly, and countless lightnings intertwined, as if they turned into an ancient thunder pattern. In the pattern, there seemed to be a giant roaring towards the sky, like a thunder god.

An extremely terrifying danger scented the world.

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

"This move..."

When Zhou Yuan was tense, the sound of murderous intent contained in the coldness of the thunder was already filled with thunder and echoing the world.

"Holy Source Technique, Nine Palaces Thunder!"

Zhou Yuan's pupils suddenly shrank.

It's indeed...Sacred Source Technique!

It seems that this guy has been really ignited.
