The frenzied fighting of the four elves was much more destructive than the two elves. The entire cave was shaking, and the rock walls continued to open cracks, as if trembling because of these terrifying auras.

Although Hei Lujia and Duck-billed Fire Dragon have the advantage of attributes, they are far worse than Big Steel Snake and Warmaul Dragon in size, so it does not have the advantage to fight.

Du Chen threw a wizard ball again: "Come out, Big Rock Snake."

The glorious crystal big rock snake appeared in the white light.

The cave that had originally appeared to be wide suddenly became a bit crowded after a giant monster measuring nearly ten meters was added.

"..." It seemed that the crystal big rock snake would suddenly appear, and the war hammer dragon and the big steel snake were obviously taken aback.

Especially the Big Steel Snake, even the attacking movement stopped, the expression of astonishment could even be seen by Du Chen, who was a human.

It seems that they know each other, and there seems to be something between this big steel snake and the crystal big rock snake.

To seize this opportunity, Hei Lujia and Duck-billed Fire Dragon use both jet flames and big-character explosions at the same time.

The big steel snake evaded in no hurry and was hit head-on.

The fire system has the best effect on the steel system.

Hahaha, Du Chen laughed in his heart. It seemed that it was the right thing to let the Crystal Big Rock Snake come out. Neither the leader-level tyrannosaurus nor the crossword bat had such a good effect.

The Warhammer Dragon roared and continued to counterattack. The Big Steel Snake obviously slowed down after receiving a heavy blow. At the same time, it paid attention to the movement of the Crystal Big Rock Snake from time to time.

"What does this big steel snake have to do with you?" Du Chen asked Dayan snake with a spiritual thread.

"It is the leader of our Rock Snake Clan, and the master who helped me transform into a crystal body." From the emotions of the Crystal Rock Snake, Du Chen could feel its anxiety at the moment.

Transforming into a crystal body, that is to say, becoming a crystal is not a natural mutation, but an acquired completion...

"The big rock snake, attack the big steel snake, use the dragon's breath." Du Chen said.

The color of struggling flashed in the big rock snake's eyes, but it still spouted a burst of purple-red energy and attacked the big steel snake.

Du Chen naturally didn't think that the Big Rock Snake, which was strong enough to even the elite level, could hurt the Big Steel Snake, just to see if its attack would have any psychological impact on the Big Steel Snake.

The purple-red energy bombarded the big steel snake, and even the effect of causing it to sway could not be caused, but it succeeded in attracting most of its attention, causing it to attack the duck-billed fire dragon with flaws.

Hey, as expected, this crystal rock snake has a great influence on it.

"Good opportunity, use strange light." Du Chen shouted.

When the opponent is not concentrated, it is also the time to concentrate on attacking it.

At this moment, the duck-billed fire dragon, who was supposed to release the strange light to confuse the opponent, stopped and took a beat. Instead of hitting the opponent, it was swept away by the dragon's tail attack of the steel snake.

The flame burst, and the flame-shaped armor of the duck-billed fire dragon was almost shattered.

what happened……

Du Chen frowned slightly, and the leader-level duck-billed fire dragon didn't suffer much damage in the previous battle. How could it be sluggish?

Du Chen repeated the old tricks, causing Hei Lujia to entangle the Warhammer Dragon, and once again used the Big Rock Snake to attract the attention of the Big Steel Snake, and this time he used his body to strike.

Sure enough, the steel snake threw the rat avoidance device and twisted his body to avoid it, as if he was afraid of hurting the crystal rock snake.

"Come on again, explode with big characters." Du Chen seized the opportunity to shout.

"Roar~" The duckbill fire dragon's mouth was vomiting flames, preparing to turn it into a "big" font attack.

But for some reason, its movements were once again sluggish, and the flame that hit the big steel snake was easily avoided by it.

Sure enough, there was a problem, Du Chen's eyes flashed brilliance, and he threw out the Pokemon Ball.

"Cross-character bat, use ultrasound."

Although the four-winged purple bat elves appeared, circles of ultrasonic waves began to sway in the cave.

Found.

Through the radar-like ultrasonic echo, the fork bat instantly found an invisible sound shadow in the cave.

The four wings waved and shot hundreds of blue air blades, attacking a corner of the hole from all angles in all directions.

Air cutting.

A light blue brilliance rose up like a curtain of water, blocking all incoming air blades. A white and green wizard appeared.

Xanadu.

Du Chen's eyes narrowed, and this Xanadu was larger, with red pectoral fins separated on two sides like a butterfly. It turned out to be a million Xanadu that had evolved from mega.

With the appearance of Super Xanadu, a burst of unparalleled mental power squeezed the audience, causing the four great elves to stop their movements at the same time.

King class.

At any time, the king-level can only be confronted by the king-level, not even the leader-level peak.

"Human, you and your companions broke into the crystal cave and have caused huge damage, now it's time to leave." A gentle female voice sounded in Du Chen's spirit.

"We came in accidentally, but the elves in the cave attacked us for no reason. Two people are now dead." Du Chen smiled and said, "Do you want us to leave like this?"

"I just prevented your elves from harming the elves here, and didn't attack them, and you should know that if you continue to fight, you have no chance of winning." The female voice continued.

It seems that this Shanaido is the king here.

Only a huge wild elven race can give birth to a king-level leader, and there will not be two king-level leaders in the same wild elven race.

"If I don't have any chance of winning, why don't you just do it?" Du Chen said, throwing the elf ball on his waist.

Two groups of white lights flashed, and the tyrannosaurus and double bomb gas appeared in place.

Adding Du Chen Duckbill Fire Dragon, Black Lujia, Three-in-One Magneto, and Crossword Bat, there are a total of six leader-level and one crystal big rock snake that has no combat effectiveness but can make the steel snake scruples.

"Fighting desperately, I'm afraid this beautiful crystal cave can't bear it." Du Chen smiled.

"Then what do you want?" Shanaido's voice was still so gentle, it seemed that there would be no other mood swings.

"It's not very good." Du Chen paused: "There seems to be a magical power that can transform the rock elves into water crystals. I am an elven researcher and I just want to study."

"That's it." Million Xanadu nodded: "It's not a difficult thing. There is a ritual for the crystalization of the rock elves. I can tell you, but you must leave afterwards, okay?"

"Good." Du Chen nodded.

"Then I will come with me." Shanaidoshi Shiran walked by Hei Lujia and the duck-billed fire dragon, not afraid that they would take the opportunity to attack.

This is the confidence of the king class.

Du Chen saw that the direction it was heading was exactly the hollow in the center with three huge crystal pillars.

Du Chen was surrounded by his own elves, slowly following Shanaiduo's pace.

He could feel that the entire crystal cave seemed to be quiet at this time, but it was not like the calm and calm after the war, but more like the last peace before the storm came.
