"Roar!!"

The roar that resounded through the heavens and the earth sounded from the back of the fortress city, compared to this roar, not to mention comparing the sixth-order Flying Dragon Emperor with the other party, even the roars of those seventh-order dragon clan troops that Xu Yun had seen in the national war were definitely the difference between a kitten and a lion.

Fortunately, Xu Yun's body couldn't move for only a moment, and after the roar, he was finally able to move freely, but he felt that his body was much heavier than normal.

Glancing at the system panel, there is an additional status on it at this time.

Long Wei: Movement speed is reduced by 10%, and the chance of creatures outside the dragon army falling into a state of chaos for one second, depending on the rank, each time there is a state of chaos, the chance of reappearing in a state of chaos is reduced by half.

The explanation is very simple, but this state clearly tells Xu Yun what he has encountered now.

"Dragons?".

Xu Yun has seen all the dragon classes of the seventh-order troops of the nine camps, whether it is the black of the dungeon, the bone dragon of the cemetery, or the golden dragon of the barrier, there has never been such a thing as dragon power.

Therefore, Xu Yun knew that it was absolutely impossible for him to encounter these three dragons now, and the roars of these seventh-order troops did not have such domineering power.

Before Xu Yun could figure out where this Long Wei came from, the target automatically appeared.

"Whoa!"

The sound of a huge crystal collision sounded from the back of the barrier city, and the sound was so loud that Xu Yun, a person who was more than half a kilometer away from the barrier city, could hear it clearly.

And then!

A huge, seemingly crystal-sized, mountain-sized monster slowly stood up.

The appearance of the monster is somewhat similar to that of the dragon class, but it does not have the wings unique to the dragon class, and the whole body is composed of red crystals, if it were not for the state of dragon power on the system panel, Xu Yun really didn't dare to imagine that this crystal monster was a dragon clan.

The wall of the fortress city is more than ten meters high, this height is not low, but compared with such a high city wall and the crystal monster, it can only cover the lower body of the crystal monster, the upper half of the crystal monster is more than ten meters tall from the city, and the crystal monster the size of the mountain seems to be able to destroy the barrier city in front of it with a gentle push with two front paws.

"What is this?" Looking at the crystal monster standing a hundred meters away from the back of the barrier city, Xu Yun's heart had collapsed, he had never thought that he would encounter this kind of monster, this is obviously not an ordinary monster, this is completely the kind of ultimate boss that will only appear in the later stages of the game.

"Boom!!"

The crystal dragon bypassed the barrier city in front of him and walked towards Xu Yun's side, and its hind limbs trampled on the ground with a loud bang as it went.

Although the movement of this crystal dragon is slow, because its body is too large, even if it moves slowly, its forward speed is not slower than that of ordinary melee troops.

"My lord, let's withdraw first!" , Joan of Arc hurriedly reminded Xu Yun that if he didn't retreat, it would be too late.

Although he had never seen this kind of crystal monster, Joan of Arc knew an iron rule in the Isfil world, that is, powerful creatures were not necessarily large, but huge creatures must be powerful, and this monster in front of them, which was several times larger than all the seventh-order creatures in the nine camps, was definitely not an opponent they could take.

Hearing Joan of Arc's reminder, Xu Yun knew that he should retreat, but he was very unwilling, because there were more than a dozen crystal mines waiting for him to occupy in front of him, and he retreated because of the appearance of a monster he didn't know, which really made him speechless.

"Joan of Arc! , you command the troops to retreat first! , the angel team stays", Xu Yun's eyes flashed coldly, he was really unwilling to leave like this, and decided to test the strength of this monster before leaving, at least he had to do something for the next time he captured this plane fragment.

Joan of Arc, who had long been accustomed to obeying Xu Yun's command, began to act, and the troops retreated in the direction of the portal like a tide, only Xu Yun and the angel team remained, because there was still the Flying Dragon Emperor in the troop card, so Xu Yun was not worried about whether he could retreat in time, but quietly looked at the crystal dragon in the distance.

"Rebecca, use the Sword of Divine Punishment!" , Xu Yun decided to let Rebecca use the strongest blow, anyway, he now has a few units of gems on his body, and he is not afraid that Rebecca will fall into a weak state after using the Sword of Divine Punishment.

"Yes, sir!" Rebecca spread her wings and flew up, and the other angels followed suit.

"Boom!"

After Rebecca flew into the air, she immediately ignited the holy flame on her body, and then pulled out two sacred swords to collide, and the three-meter-long divine sword reappeared, and then she held the holy sword high in her right hand, and the holy flame surged towards the divine sword.

Below

The crystal dragon who had just bypassed the fortress city seemed to sense something, and stopped his steps and raised his head to look at Rebecca in the sky.

"Are you scared?" Seeing that the other party stopped advancing, Xu Yun thought that the crystal dragon did not dare to enter the attack range of Rebecca's Divine Punishment Sword, but it turned out that he was thinking too much.

Bang!!

Lowering its massive head, the Crystal Dragon continued to move forward, its body, several times larger than the Ultimate Hydra, causing the ground to shake slightly as it walked.

Releasing the Flying Dragon Emperor from the Troop Carrying Card, Xu Yun flew up on the Flying Dragon Emperor without hesitation, he didn't dare to risk waiting for the other party to approach before taking off.

The Crystal Dragon's movements seemed to be slow, but it was actually moving at a decent speed, and the distance of a few hundred meters was quickly crossed by it, and it came within a hundred meters of Rebecca.

"Sword of Divine Punishment!!"

Throwing the ten-meter-long divine sword in her right hand downward, Rebecca unleashed her strongest blow at the crystal dragon.

The sword of divine punishment that shot out of Rebecca's hand easily hit the head of the crystal dragon below, to be precise, the crystal dragon did not do any dodging action at all, but just stopped moving forward and closed his eyes, as if he had no fear of this divine punishment sword at all.

"Boom!!"

The sword of divine punishment that hit the head of the crystal dragon exploded, and the golden flames instantly engulfed the head the size of a small hill of the crystal dragon.

A few seconds later

"Didn't it work?" , Seeing that the crystal dragon's mountain-sized body did not shake in the slightest, there was no need to wait for the holy flame that the sword of divine punishment exploded to extinguish, Xu Yun also knew the result, if he caused a lot of serious injuries to the crystal dragon, how could the other party have to react.

Sure enough, when the golden flame dissipated, the crystal dragon's head did not have half a wound, only some small crystals fell off it, proving that Rebecca's blow was not a failure.

"Roar!"

After being attacked by Rebecca, the crystal dragon opened its eyes and stared at Rebecca in the air, letting out an angry roar, but it had nothing to do with Rebecca flying at an altitude of more than 100 meters.

"Let's go, Rebecca!" , Xu Yun commanded the Flying Dragon Emperor to come forward to catch Rebecca, who was exhausted, and handed over a unit of gems to Rebecca to restore her strength.

Xu Yun is completely dead now, the following dragon monster composed of crystals is not something he can challenge with his current strength at all, those wood elves may also be so tough because of the protection of this crystal dragon, fortunately, because of the rules and restrictions, this monster can't get out of this plane fragment, otherwise Xu Yun will have to consider whether he should develop in a different place.

Of course, the speed of the flying class is much faster than that on the ground, so although Xu Yun retreated late, he still returned to the portal with Rebecca.

The troops withdrew in an orderly manner under the command of Joan of Arc, and the last person to step through the portal was Xu Yun.

Looking at the crystal dragon that was walking towards the portal a hundred meters behind him, Xu Yun knew that he didn't have the idea of fighting this plane fragment before he didn't have the strength to kill this crystal dragon, although there were a large number of third-order wooden houses and more than a dozen crystal mines, as well as a barrier city.

But when Xu Yun was about to leave, he received a system prompt.

[Ding, task tips, please check the task content by yourself!] 】

The system prompt sounded in his ears, but Xu Yun didn't have time to check this sudden mission prompt now, because the crystal dragon was only a few dozen meters away from him, and if he didn't leave, he would have to die back to the city, so he decisively stepped into the portal.

Xu Yun had just disappeared when a huge foot stepped on the front of the portal.

"Boom!!" , The crystal dragon stepped on the angry foot, and the ground shook slightly, but unfortunately in the face of the enemy who had teleported away, even if the crystal dragon was strong, it was impossible to attack, and the portal was unharmed under the protection of the rules.

……

The blue light gate fluctuated, and Xu Yun quickly walked out of it, he was almost about to die back to the city just now.

"Xiaosheng, Slash the Heavens, let's retreat and leave this plane fragment to the people of the Infinity Serpent, hoping that they will be satisfied with the 'gift' I prepared for them."

As soon as he teleported back, Xu Yun was ready to retreat and leave, this plane fragment has this crystal dragon anyway, I believe that no one can take it in a short time, and if the people of the Infinite Serpent really dare to enter, I believe that the crystal dragon who was led to the portal by himself will definitely help him 'entertain' the people of the Infinity Serpent.

Although they didn't know why their own head of the regiment would give up this plane fragment that they had so hard to grab, Bai Xiaosheng and Heaven-Chopping Moon knew from listening to their tones that now was not the time to ask, so they immediately began to command the troops to retreat according to Xu Yun's instructions.

On the way, Xu Yun told Bai Xiaosheng and the Heavens and Moons all about what happened in the plane fragments.

"I see, I'll just say that you didn't retreat because you were afraid that the people of the Infinity Serpent would come back!" , Cutting the Sky and the Moon finally understood, Xu Yun did not retreat because he was afraid that the Infinite Serpent would come back, but because there was no way to take down this plane fragment, and he was also ready to use this plane fragment to pit the opponent's hand.

Bai Xiaosheng thought of another question

"Commander, you said that monster is countless stronger than Rebecca in its ultimate form, so could the other party be a higher-level class?"

Hearing Bai Xiaosheng's bold idea, Xu Yun nodded.

He actually has this idea, because although the seventh-order class belongs to the final class in Eve's division, Eve did not say that the highest class in the game is only the seventh order, and there may be higher-level troops, but now only he has access to it.

However, now that Xu Yun's territory has not even built a fourth-order military camp, it is too early to think about this, so he first opened the task he had just received when he left the plane fragment, and he wanted to know who gave him this task.
