At this time, Zhan Chen's Immortal Yuan had just recovered halfway, but looking at the formation in the sky, another vicious battle was inevitable.

In the end, all the sawdust on the ground ran to the sky, forming a huge wooden dragon, the wooden dragon was more than 10,000 meters long, every piece of scale armor was clearly visible, and the eyeballs were constantly rolling full of spirituality, and gradually it focused its gaze on Zhan Chen on the ground.

Zhan Chen felt a strong sense of oppression, this sense of oppression could only be felt when he faced the Enlightenment Ancestor, it seemed that this time, he was going to face the biggest challenge ever.

Suddenly, the demon dragon opened its mouth and let out an earth-shattering roar, and the wind carried the dragon's roar like ripples, and the earth beat everywhere it passed.

Zhan Chen was forced to retreat again and again by this wave of qi, and there was also a feeling of churning qi and blood in his body.

Before he could recover his strength, the demon dragon condescended and swooped towards Zhan Chen, and the process of its swooping formed a powerful coercion, firmly holding Zhan Chen in place, making it difficult for him to move.

"Cloud Dragon Illusion!" Zhan Chen shouted, his body turned into smoke and scattered, and the demon dragon paused in mid-air for a moment because it couldn't find a target for the time being, but it immediately no longer hesitated, but raised its incomparably huge dragon claw and slapped it fiercely at the place where Zhan Chen had stayed.

"Boom!" There was a loud bang, the mud and rocks splashed, and the ground collapsed in an instant, leaving a huge deep pit, bottomless, and the large fog formed by Zhan Chen's Cloud Dragon Transformation was also blown away, disappearing without a trace.

In a place on the edge of the deep pit, Zhan Chen was gray-faced, although he avoided the frontal blow of the demon dragon just now, but the aftermath of the attack could not be avoided, he was directly lifted away by the strong shock wave and fell into the soil.

Regardless of the dust on his face, he quickly got up from the ground and assessed the combat power of the demon dragon, this dragon composed entirely of sawdust, its strength is comparable to his own, you know, he has the cultivation of the power saint, three billion catties of strange power, but fortunately, the attack of this big guy seems to be relatively single, if it is a genius of the Great Perfection of the Yuan Shen, it should be able to deal with it.

"I have to fight quickly!" A hint of determination flashed in Zhan Chen's eyes, and he injected all the part of the immortal yuan that had just been recovered into the Youlong Horror Sword, and muttered: "Just use my new swordsmanship to fight against you, this evil animal, look at the moves, and breathe through Changhong!"

The sword attacked, and the Dragon Horror Sword shot out like an off-string arrow, pointing directly at the demon dragon, and in the blink of an eye, a large hole with a diameter of three hundred zhang was drilled in the demon dragon's body.

The demon dragon roared again, as if it was really alive, and finally hit it hard, and the corners of Zhan Chen's mouth unconsciously showed a hint of a smile, but this smile quickly froze, because the big hole was quickly filled with new sawdust, and the demon dragon immediately recovered as before, and pounced again with teeth and claws.

Seeing that it was coming violently, Zhan Chen simply summoned another mixed dragon sword, and his mouth bloomed with spring thunder: "Liangyi is windy!"

The two swords immediately swam around him, forming a strong whirlwind that firmly protected Zhan Chen's body in the center of the whirlwind.

The claws of the demon dragon slapped on the wind wall, and it couldn't move an inch, but was worn off by the wind blade, but it had the ability to regenerate, and the severed limbs were quickly reborn.

Seeing that it could use sawdust to replenish its own damage, Zhan Chen muttered: "Since you can recover, I will beat you until you can't recover, and you will be able to transform the Yuan Sword with one gas!"

The whirlwind was automatically lifted, and the Dragon Horror Sword disappeared into a shape, turned into an invisible sword, and slashed at the demon dragon's body, a gas Yuan Sword has the power of the origin, which can turn everything into nothingness, and the strong sword qi broke the demon dragon's body into two at once, and the interrupted part disappeared out of thin air, and it was turned into the smallest particle by the Zhanchen Sword.

Losing the dominance of the upper part, half of the demon dragon's dragon body finally collapsed, turned into sawdust, and sprinkled the earth, but the hundred-legged insect died but did not stiffen, and the upper half of the demon dragon's body could still move, and still fiercely launched an attack on Zhan Chen.

Seeing it rushing towards him again, Zhan Chen breathed a sigh of relief, he was most afraid that there was no way to crack it, knowing that a Qi Yuan Sword could defeat it, and the rest would be easy to do.

Zhan Chen poured all his last immortal yuan into the Dragon Frightening Sword, and shouted, "Die, Demon Dragon!"

The invisible sword was unsheathed again, this time directly aimed at the dragon head of the demon dragon, only to hear the sound of "boom!", the dragon head exploded in mid-air, and the demon dragon could no longer recover, turning into a team of pieces.

At this moment, Zhan Chen noticed a strange flickering light in the scattered wood, as if something was hidden inside.

"Could it be that this is the treasure in Guanghong's secret collection!" Zhan Chen's eyes flashed with excitement, and he flew forward with an arrow step, grabbed the contents in the palm of his hand, and looked at it, it was actually a jade slip, and the surface of the jade slip was engraved with several big characters "Canglong Huitian Seal".

"This is an exercise!" Zhan Chen immediately reacted, stretched out his immortal consciousness into the jade slip to read the information inside, his face immediately showed a look of ecstasy, and read: "Canglong Huitian Seal, the best secret technique of the immortal level!"

Most of the immortal-level best secret techniques are the exclusive privileges of the Enlightened Ancestors, and even many Enlightened Ancestors have not yet mastered a secret technique, because on the Ten Thousand Laws Continent, the status of the secret technique and the mental method are equal, and even some peculiar secret techniques are far more valuable than some of the same level of mental techniques, although Zhan Chen has not yet interpreted the content of this jade slip in detail, but Guanghong Zhenren, a generation of giants, his collection should not be bad.

With the disappearance of the demon dragon, a teleportation array appeared beside Zhan Chen out of thin air, seeing this, he didn't have time to think about it, stuffed the jade slip into the storage ring, and stepped on the teleportation array, because he was afraid that this teleportation array would disappear out of thin air, then he was afraid that he would be trapped in this dead space.

The light flashed, and Zhan Chen disappeared in place, and when he opened his eyes again, he had already appeared in an unfamiliar hall. The walls, roof, and even the floor of the hall are painted with various patterns of gods, demons, and monsters, which looks quite weird.

There were a dozen other people with him, some of them unfamiliar faces, and he thought to himself, "What's the matter? There are people here that I don't know, could it be that they came in after me?"

While thinking about it, a light flashed in the center of the hall, and a figure flashed, and everyone focused their eyes on it.

The phantom glanced at the people present and said with a smile: "Everyone, congratulations on passing the first level of the trial, of course, you are not the only ones who have passed the first level, the others who have advanced will accept the second level of the trial in other places, and this game will continue to loop and will not stop, unless you can find a clue to leave here." But rest assured, after each round of trials, you will be rewarded, and these rewards will benefit you greatly—"

"Old man, don't talk nonsense, tell us about the second level!" a rough-looking man cried out.

"Hehe, these two levels are naturally much more difficult than the first level, and this level tests your mental strength, but I can only prompt here, otherwise it won't be fun. The Phantom stroked his beard, and with a wave of his hand, the door behind him opened, revealing a deep passageway.

He continued: "The name of the second level is called the Reverse Labyrinth, and the first person to crack the maze can get great benefits, everyone work hard, and the old man will go first." With that, he disappeared where he was, and almost everyone present rushed towards the passage, as if one step behind, the treasure belonged to someone else.

Zhan Chen was not as excited as the others, but slowly walked towards the door, at this time his heart was still recalling the words that Guanghong Real Phantom had just said, and he was thinking in his heart: "This reversal maze must not be so simple, you can find the exit one step ahead of the speed alone, how can there be such a thing? I have to be careful, according to Guanghong's character, there must be many mechanisms arranged in it." ”
