Zi Chen rushed out of the cave, and the Black Eagle attacked again. The sharp claws shook the space and grabbed towards Zi Chen.

"Damn it!"

Zi Chen scolded angrily, and the realm immediately skyrocketed, and he slashed with a knife.

"Boom!"

In a sonorous sound, the Black Hawk was struck and flew up.

In just half a month, Black Eagle's injuries were completely recovered, and this speed of recovery made Zi Chen very surprised.

But obviously, this guy is a brute who holds a grudge, and he forgot his original scar just after his injury, and came to trouble Zichen again.

This time, Zi Chen was no longer polite, and borrowed the virtual realm to start crushing the Black Eagle. There is no way, if you don't use the virtual realm, then he can only be crushed.

"Peng!"

"Boom!"

"Boom!"

"Aang!"

"Get out!"

One man and one eagle fought fiercely again, and the battle was inextricable, as time went by, the black eagle gradually had more wounds on his body, Zi Chen was also very wolf, his clothes were broken, and there were several scratches on his body.

It was another day and a night of fierce fighting, and the black eagle, who was covered in injuries, glanced at Zi Chen with disdain, and with a 'ang' sound, he flapped his wings and left.

"Brute, stop me!"

Black Eagle's disdain completely angered Zi Chen, he shouted, and took off into the air to pursue Black Hawk.

Although he is very wolf, the Black Hawk's injuries are obviously more serious, why does this beast look down on him?

This is the source and root of Zi Chen's anger.

But it's a pity that he didn't comprehend the nine deaths of thunder and lightning at all, and the speed was naturally too much worse than that of Black Hawk, and after a few breaths, Zi Chen found that there was no target in his sight.

"Wait, dare to come again, I will kill you!"

Zi Chen was angry, his body fell from the sky, looking at the messy battlefield, looking at the mountain peaks that were almost half destroyed, and his anger continued to burn.

He secretly swore that next time Black Hawk dared to come, he would definitely kill it.

This should be the territory of the Black Eagle, there are no other war beasts around, and the monks dare not go deeper, Zi Chen simply no longer prohibited, and continue to comprehend the nine deaths of thunder and lightning.

Zi Chen's spiritual thoughts are known as perfect, and the speed of comprehending every exercise is very fast, and the same is true of the Nine Deaths of Thunder and Lightning.

Although the comprehension is fast, because the complete Nine Deaths of Thunder and Lightning are too mysterious, and it involves spatial truths, it will take a long time to fully grasp them.

Soon, half a month passed, and just when Zi Chen suddenly felt uneasy in his heart, a harsh voice came into his ears again.

Because it sounded suddenly, it directly startled Zi Chen, and at the same time, the sound shook Zi Chen's head a little foggy.

"Damn, it's here again!"

Zi Chen, who reacted, was furious, and the thunder wing on his back appeared instantly, and then vibrated the thunder wing, clenched the black knife, and rushed outside to kill.

"Whew!"

As soon as he appeared, there was a sound of breaking the air, and Zi Chen turned around and saw a large stone whistling towards him. On top of the boulder, there is a layer of streamer completely wrapped, which is obviously the mana of the Black Eagle.

This blow was full of power, and Zi Chen had to pay attention to it.

He raised his long knife aloft, the powerful power in his body poured into the blade, and then slashed at the boulder.

"Poof!"

Under the breaking of the rules, the light on the surface of the boulder body was slashed, and the boulder was slashed open with a single blow, and then exploded.

This blow was broken, but Zi Chen suddenly had a sense of crisis, and his figure flashed subconsciously, dodging to the side at extreme speed.

"Poof!"

I saw that the black eagle above Zi Chen's head suddenly appeared, and its claws grabbed Zi Chen's head, but Zi Chen dodged in time, just grabbed Zi Chen's shoulder, and grabbed a piece of meat vigorously.

Grabbing Zi Chen's flesh and blood on the claws, the black eagle glanced at Zi Chen indifferently, with a certain smugness in his eyes, and then swallowed the meat in one bite.

It seemed that Zi Chen's meat was very delicious, and Black Eagle's expression actually became intoxicated, and when he opened his eyes again, his eyes were full of light when he looked at Zi Chen.

It's like in the mortal world, beggars see gold, hungry sweat see food, and perverts see beautiful women.

Zi Chen felt a chill in his heart, and then he slashed with a knife.

One after another, the swords appeared like a dense net, falling towards the black eagle.

"I'll hack you!

With every knife, Zi Chen shouted, and it was obvious that he, who was rarely provoked, was completely angered by this hateful black eagle.

The battle resumed, and the sound of the eagle resounded, because Zi Chen was completely angry, and it was completely a deadly way of fighting, so this time the battle only lasted for a day, and the black eagle fled.

Zi Chen still didn't catch up with the other party, he was angry and unwilling, but he could only accept his fate and continue to come back to comprehend the nine deaths of thunder and lightning.

"Wait, when my thunder and lightning are complete, I will definitely cut off your head!" Zi Chen swore viciously.

The time seemed to be calculated, and the two sides seemed to have completely agreed, and every half a month in the future, Black Eagle would appear and fight Zi Chen.

The battle between the two is a battle of life and death, but unfortunately no one can help anyone.

And as the battle grew, Zi Chen found that Black Eagle was actually improving. And the speed of the other party's progress was far beyond Zi Chen's expectations.

For example, every time the Black Hawk attacked, it would make a whooshing sound that everyone could hear.

But now, the other party is like a killer, hiding in the shadows and suddenly attacking, and rarely chirping. Sometimes the chirp is more like confusing Zi Chen.

This is a human method, and the Black Eagle has completely learned it, used it on Zi Chen, and also made Zi Chen hang up.

Zi Chen's previous battles were bright, great, and wonderful, but as he fought with Black Hawk, he became cautious. Of course, being careful is just at best, but in fact it has become extremely obscene, and the clone that was always used for head-on battles is now used for sneak attacks, used to confuse Black Hawk.

In short, one person and one eagle began to use their own techniques, to the best of their ability, and then calculated each other.

And the two also won and lost, but each time they fought for a maximum of one day and one night, the Black Hawk would leave.

Sometimes, Zi Chen would show weakness with serious injuries, but the other party still ignored it, and when he left, the disdain in his eyes seemed to say that Zi Chen's acting skills were too bad.

Zi Chen was angry and began to pursue.

After the death of the thunderbolt, he became more and more proficient in cultivation, but it turned out that there is never a so-called first in this world.

There is only better, there is no best, and the same speed is only faster, not the fastest.

At the very least, Zi Chen's current extreme speed still can't catch up with Black Eagle. Because the last passing of the Nine Deaths of Thunder and Lightning involves the use of the power of space, if you want to fully exert the speed of the Nine Deaths, only Zi Chen can reach the true reality.

Black Eagle ran away, and Zi Chen angrily scolded. These days, he is obviously in a passive state, the other party can come when he wants to, and leave when he wants, which makes Zi Chen very unhappy.

"You wait, I will definitely kill you!" Zi Chen swore again in his heart, and every time Black Hawk fled, he almost swore an oath.

The original giant peak is now half gone, and the ancient forest in front of the cave has long been destroyed and turned into a vacant land.

"Damn, brute, you're waiting!"

Zi Chen scolded angrily again, then vibrated the thunder wings, and began to practice extreme speed in this clearing, striving to go further.

Half a moon later, the black eagle came again, and then trampled the mountain peaks a little, and the angry Zichen shouted. After a day and a night of fierce fighting between the two sides, the wounded Black Eagle left in style, still glancing at Zi Chen with disdain before leaving.

This time, Zi Chen was not angry, and after watching the black eagle leave, he did not continue to swear. There was a worried look on his face, and for the first time, he wanted to get out of here.

Because he found that with several battles, Black Hawk had increased a lot in terms of strength and combat power. Although he has improved in these years, it is much slower than that of Black Hawk.

What he was worried about now was that once a long time passed, Black Eagle would completely break through to the general level and reach the spirit level. And at that time, Black Eagle's combat power will increase by several times or even dozens of times, and Zi Chen will be completely abused at that time.

And the speed of the Black Hawk is still fast, and Zi Chen can't run away if he wants to.

Zi Chen had the idea of leaving, but he was reluctant to use this sparring partner, because of the fierce fighting during this time, he also had signs of breaking the realm.

In the midst of this entanglement and contradiction, half a month passed, and Black Eagle came again.

As a result, Zi Chen rose to the sky with his sword, and it was another fierce battle.

In this battle, Zi Chen fought very happily, and the previous entanglement disappeared, and he didn't leave.

At the very least, he won't leave until he breaks through.

As for Black Hawk wanting to advance to a big realm, I am afraid that it will not be possible to complete it in a short period of time.

So, every half month, Zi Chen fought against Black Eagle more than thirty times, and the time was about to pass for two years.

In the past two years, the two sides have become more and more familiar, and it is almost difficult to hurt each other later.

Zi Chen had reached the critical moment of breaking the realm, and he couldn't wait for the Black Eagle to come and fight every day, and he had already made up his mind that once the breakthrough reached the late stage of the Diyuan, he would leave immediately.

"Boom!"

The cave shook again, the rocks began to roll down, and Zi Chen, who was cultivating cross-legged with his eyes closed, opened his eyes, and a fine light flashed in his eyes.

"Here we go again!"

The black knife instantly appeared in his hand, and then Zi Chen rushed out of the hole, and sure enough, he saw the black eagle appear in the air.

But at this moment, Black Eagle did not look at Zi Chen, but at the mountain beside Zi Chen, and his expression became more solemn than ever.

"Didn't you make it?" Zi Chen's face also had a strange look, and then he turned his head to look behind him.

I saw that the mountain behind me, which had been cut off by three-quarters, was constantly shaking, and from the bottom of the mountain, cracks spread out one after another, and the cracks went from the bottom to the top, and then reached the top and shattered the mountain.

As the mountain cracked and rocks rolled down, a tyrannical aura spread from the bottom of the mountain.

"Aang!"

The moment he felt this breath, the black eagle spread its wings and flew up, and let out a high-pitched chirp. There was anger and panic in the scream.

The moment Zi Chen felt this breath, his face also changed greatly, and he shouted, "Spirit-level war beast!"

Spirit-level war beasts are comparable to the reality of human beings, if according to the algorithm of this world, every war beast can fight beyond the level, the spirit-level war beasts can already be compared to the realm in the human world.
