From the early stage to the middle stage, although it was only a small breakthrough, it was a big step for Zi Chen.

Realm breakthrough means that the combat power has increased again, although he can still slaughter in the face of the virtual realm, but when facing the real realm, it is a little more self-preservation.

Coming to the Zhanwu Continent to break through a small realm in just a few years, this speed Zi Chen is still very satisfied. You must know that if you change to someone else, you may not be able to break through a small realm for more than 100 years.

After the breakthrough, Zichen continued his retreat.

One is to be familiar with the current strength, and the other is because the rule fragments have not been consumed, and Zi Chen doesn't want to go out yet.

The time of retreat is extremely boring, but in order to survive, no matter how boring it is, it has to continue.

Next, Zi Chen spent nearly ten years refining the rule fragments again, and during this period, his strength was also growing, and he was already very close to the late stage of the Earth Yuan, but because of the perennial retreat, his realm ascension became slow.

Even if you have enough resources, it will take hundreds or even hundreds of years to break through to the virtual realm.

In addition to retreat and cultivation, the perception of the state of mind is also very important, and at the same time, the state of mind determines the growth rate of strength. So, theoretically speaking, there is no such thing as a single retreat that can reach a very high level.

Except, of course, for higher life.

After feeling that the growth of strength had become slow, Zi Chen decisively gave up cultivation, and it happened that the rule fragments had also consumed too much, and it was time to get some.

However, before that, it was necessary for Zi Chen to refine the Thunder Wing again.

The demonic qi on the Heavenly Thunder Wing has been gradually dispelled in the past ten years, and what Zi Chen needs to do is to refine and fuse again, and I believe that the power of the Thunder Wing can be stronger again.

"Boom!"

A tremor suddenly came out, and Zi Chen's ban for more than ten years was torn apart by a powerful force, and then a high-pitched chirp came into Zi Chen's ears.

"Is it a war beast?" Zi Chen looked surprised.

"Boom!" the cave where Zi Chen was located shook again, and then the sound of a large stone rolling down sounded.

Obviously, this is a war beast attacking the mountain.

"It's amazing that you can find out about the ban on my cloth. Zi Chen sighed.

"Boom!" "Boom!"......

Before Zi Chen could get up, the sound of explosions sounded again and again, and the entire cave continued to vibrate, and a tyrannical aura swept from outside the cave, like a sharp blade with a handle, rushing towards his face.

"Huh!"

Zi Chen's sleeves waved, a wave of energy swirled, and the cold aura dissipated. Immediately after, Zi Chen's figure flashed and swept towards the outside of the cave.

The sky outside the cave was gloomy, and as soon as Zi Chen appeared, he felt a dangerous aura appear from above his head.

He looked up and saw that a behemoth that covered the sky had landed, its sharp claws grabbing at Zi Chen's head.

It was an eagle-like war beast with pitch-black feathers and a pair of sharp eyes that radiated an icy light.

Seeing such a scene, Zi Chen's expression remained unchanged, and the black knife in his hand immediately appeared, slashing towards the claws.

"Boom!"

The sword collided with the claw, and a sonorous sound erupted, and at the same time, Zi Chen felt a huge force coming out through the long knife, shaking him upside down and flying out.

"Aang!"

Seeing that the human being was shocked by a blow, the black eagle's expression became more and more cold, and as soon as his wings fluttered, he headed towards Zichen at great speed.

The wings of the black eagle slashed across the ancient tree, and the ancient tree broke off at the waist, as if it had been cut by a sharp blade, and the cut was neat and smooth.

The Black Eagle was in the blink of an eye, and its extreme speed was the only thing Zi Chen had ever seen in his life since he came here, even faster than the flying boat, and he couldn't help but be taken aback. He stepped forward, swung his knife and slashed again.

He was only blown away by the blow just now, but he was not injured.

"Boom!"

The strong collided, the sonorous sound rose again, and the powerful force came out, Zi Chen retreated again, feeling numb.

This Black Hawk is very fast, and his strength is also extremely powerful, and it is obviously a general-level war beast.

"Qiang!", "Qiang!", "Qiang!", ......

The black eagle obviously had the upper hand, attacking again and again, hitting several times in a row, although Zi Chen could block it every time, but he couldn't prevent the opponent's powerful power at all, and when his body flew upside down, he also broke a lot of ancient trees.

Zi Chen, who has always crossed the level to kill enemies, has always been below, he has to admit that the Black Eagle is powerful, and with his own strength, he can't beat the Black Eagle in front of him at all.

was repulsed again and again, Zi Chen's arm was numb from the shock, and the tiger's mouth showed signs of cracking.

The black eagle's expression became more and more cold, thinking that it was another war beast that had arrived at the habitat of the giant python, but he didn't expect it to be a human after the explosion.

It roared in a high-pitched voice, and rushed towards Zi Chen again, its claws like space weapons, with full lethality.

"Get out!"

Zi Chen burst out and began to mobilize the power of the void in the Heavenly Thunder Wing, and the realm of the Earth Yuan continued to skyrocket.

In the late stage of the Earth Yuan, the peak, skyrocketed to the early stage of the Void Realm, the peak of the early stage, and the middle stage of the Void Realm......

When the realm was about to reach the peak of the middle stage, it stopped, and the Heavenly Thunder Wing completely raised a large realm for Zi Chen.

Zi Chen felt an abundant force fill his body, he held the knife, and slashed forward again.

The sword-like sword shot out, with a powerful attack power hundreds of times greater than just now.

"Boom!"

But after the attack landed on the black eagle, it was heard again, and the opponent's claws had already become weapons and were indestructible.

However, the power contained in Zi Chen's blow was also surprisingly large, so he flew upside down before, and no longer retreated, and this time it was Black Eagle who was smashed away.

The black eagle was cut down by Zi Chen and flew out, because of its huge body, several ancient trees were shattered. Its cold expression changed immediately, and its eyes were filled with surprise and surprise.

"Drink!"

Zi Chen shouted again, strode forward, raised his long knife and slashed down.

"Boom!"

This blow was blocked by the black eagle with an eagle's beak, and Zi Chen still did not break through the opponent's defense.

"I don't believe it, all the defenses in your body are space weapons!"

Zi Chen's eyes widened, the golden light flashed around him, and then two more figures flew out. The two clones plus Zi Chen, the three figures rushed towards the black shadow in three directions.

"Poof!" "Poof!"

The black eagle clawed a clone, and at the same time, the eagle's beak also destroyed one, but Zi Chen's true body had already reached the opponent's side, and the long knife slashed down.

With a fierce knife falling, slashing on the pitch-black feather, Zi Chen finally heard the long-lost sound of breaking the defense. But like slashing at the toughest object in the world, more than eighty percent of the power of this blow was unloaded, and the remaining two percent entered the body, but it did no harm to Black Eagle at all.

Black Hawk was slashed again.

The Black Hawk's icy eyes turned angry after being slashed with a single blow, and then it vibrated its wings, and a devastating storm formed.

The ancient trees were uprooted, like mountains, roaring towards Zichen.

Zi Chen's void space body around him slashed towards the objects in front of him, and one after another sword rays appeared, and all the objects in front were destroyed.

"Aang!"

A chirp sounded overhead, and the black eagle fell from the sky, and its claws had reached the top of Zi Chen's head.

Zi Chen held the knife and slashed again, and the sword-like sword went up against the air.

"Bang!" ......

This is a close battle, Zi Chen has a slight advantage, but if you want to kill Black Hawk, it is simply unrealistic.

Every time he attacked, he could only leave a small wound on the black shadow's body, which were light and not fatal. Although there is a breaking rule attached to it, because the injury is so light, this breaking rule is not of much use at all.

One man and one eagle fought in the forest, and this battle was one day and one night.

Both of them are amazingly abundant, but they will not get tired.

During this period, Zi Chen also had a deeper grasp of the current strength, knowing that he could not kill the other party, he also used the black eagle to practice.

But Black Hawk didn't think so, and it was very annoyed that it couldn't kill humans for a long time.

As the fierce battle continued, the many wounds on the Black Hawk's body finally began to affect the injuries, and for the first time in its cold eyes, there was hesitation.

Looking at the human beings who are becoming more and more brave in battle, it also decisively rises to the sky and then leaves.

"Don't go!" Zi Chen shouted, then volleyed up and chased after him.

But after only a few breaths, the sky lost its tracks of the Black Hawk.

"It's quite capable of running!" Zi Chen panted, descending from the sky, looking at the battlefield around him, he also shook his head.

Black Eagle is only a general-level war beast, which can be regarded as a virtual realm, and Zi Chen's current use of thunder wings can also be regarded as a virtual realm. But he didn't kill Black Hawk, which shows how extraordinary Black Hawk is.

Moreover, this is just the first general-level war beast that Zi Chen has encountered, and for the war beast, Zi Chen is also a little more cautious in his heart again.

The black eagle wolf retreated, thinking that it should not come again, Zi Chen continued to put on a prohibition, and then returned to the cave and began to refine the Heavenly Thunder Wing again.

The Nine Deaths of Thunder and Lightning cooperate with the Heavenly Thunder Wings, known as the fastest in the world, but at present, Zi Chen has only reached the eighth death, and the ninth death has not yet been practiced. The difference is gone, and the speed of the world is a big discount.

Speed is the key to killing the enemy, but also the key to escaping, and Zi Chen has always had an advantage in speed. But today, he couldn't catch up with a black eagle, which hit him hard.

As a result, his refining of the Thunder Wing became more and more urgent, because he had a feeling that this Ninth Death Technique was very likely to be in this Thunder Wing.

Because in the original thunder wing, there was the eighth death exercise.

Soon half a month passed, Zi Chen completely fused with the Heavenly Thunder Wing, and at this moment, the Heavenly Thunder Wing exuded pure silver light, and there was not a trace of demonic energy on it.

And at the moment of fusion, Zi Chen was also pleasantly surprised to find that a kind of exercise was transmitted to his sea of consciousness along the thunder wing.

And this ...... It is precisely the complete Nine Deaths of Thunder and Lightning.

This discovery made Zi Chen extremely surprised, the thunder and lightning passed away, the world was extremely fast, and there was no life for many years, but I didn't expect that here, Zi Chen got a complete speed exercise.

With a complete exercise, it means that Zi Chen will regain the speed of the world in the future. Zi Chen looked excited, but before he could continue to explore, the cave shook again.

"Peng!"

The prohibition was broken again, and a piercing chirp came into Zi Chen's ears, shaking his eardrums.

"Damn, it's here again!" Zi Chen scolded angrily and chased after him with a black knife.
