And when everyone slowly turned their eyes on the stele, the stele collapsed with a bang.

And the stone monument that collapsed violently flew over the crowd and suspended at the entrance where the crowd came.

The stele also slowly emitted a light blue light at this moment, and this light blue light also attracted the huge stones around it, and it actually sealed the intersection when everyone came.

In the face of this sudden change, the three of them also looked at each other, not knowing what to do.

However, just as everyone looked at each other, not knowing what to do next, a line of small white letters slowly appeared in the air.

"Congratulations to the three adventurers for triggering the castle's first mission: defeat the 'Crystal Rock Serpent'. Reward: Bloodthirsty Pill (Red) ×3. ”

Looking at the small white words that suddenly appeared in the air, Yang Yilan also read them out slowly.

"This ...... What the hell is the red behind that bloodthirsty pill?" Looking at the line of small white characters in the air, Mu Chen also looked at Tan Wan with a puzzled expression.

"It should be the level of that item, right?" Facing Mu Chen's doubts, Tan Wan also replied uncertainly.

"Grade?" After listening to Tan Wan's explanation, Mu Chen still looked at Tan Wan with a confused expression.

"Hmm, you can't know the level of the item, right?" Looking at Mu Chen's eyes full of doubts, Tan Wan also knew that Mu Chen would not be pretending, but ......

As for the grading of items, even the immortal cultivators in the foundation building period who have just started to practice should know, but I didn't expect Mu Chen to know!

"The so-called grade of an item is a grade list of items that people divide according to the strength of the performance of the item.

As for the ranking of items, from weak to strong, they are white, green, blue, purple, Cheng color, red, and dark gold.

And for red quality items, such items are extremely precious, and I remember that our family has a secret method that requires the assistance of this bloodthirsty pill. Glancing at Tan Wan, who was rambling, Yang Yilan also explained directly to Mu Chen.

"Oh, then in that case, this bloodthirsty pill, we have to do it. After all, such a precious item, don't be in vain, right?"

Knowing the classification of item levels, Mu Chen also inadvertently showed an evil smile, and actually saw that Yang Yilan and Tan Wan had goosebumps.

And when Tan Wan and Yang Yilan explained to Mu Chen the gap between the division of items, in the center of the circular area, that is, where the stone tablet was originally located, a huge snake suddenly appeared out of thin air.

I saw only the huge snake, which was crystal clear, as if it had been made of crystal.

It's just that it looks like a patchwork of rocks of all sizes.

That's why it's called the Crystal Rock Serpent.

Looking at the three people in the distance, the crystal big rock snake also hissed, but the surging majestic spiritual power also suddenly dispersed, and it actually caused a huge wave out of thin air, and rushed towards the three of them fiercely.

And the spiritual power exuded by the crystal big rock snake is the distraction period.

"I'm going, why is it just a random task to ask us to fight against the strong man in the distraction period?" Sensing the spiritual power strength emanating from the crystal big rock snake, Tan Wan also looked desperate and complained weakly.

"Come on, now that the entrance has been sealed, we have no way back. Looking at Tan Wan with a desperate face, Mu Chen also patted Tan Wan's shoulder in front of him, and at the same time, the figure was also the first to burst out.

"Let's go, either fight or wait here to die. Looking at Tan Wan, Yang Yilan only left a faint sentence, and the figure shot out immediately after this Mu Chen.

"Hmm......" Looking at the crystal big rock snake in front of him, Tan Wan couldn't help but sigh softly, and finally picked up his weapon and rushed forward.

Looking at the three people who seemed to be rushing towards him, the crystal big rock snake was also fierce, waving its tail, and it was smashed towards the three of them.

"Dragon's Voice, Surround!"

Looking at the huge tail smashed by the crystal big rock snake like himself, Mu Chen also directly urged the second seal of the wooden sword, and a golden dragon also appeared out of thin air, directly winding around the tail of the crystal big rock snake.

And Mu Chen also took the opportunity to urge the third seal of the wooden sword again, "Heavenly Dao, Heavenly Dao Impermanence!"

A sharp sword qi, carrying the power of heaven and earth, also slashed towards the crystal rock snake.

Looking at Mu Chen in one go, Tan Wan and Yang Yilan's eyes were also full of shock, they didn't expect that after their original weapons, Mu Chen would become so powerful.

Tan Wan and Yang Yilan also glanced at each other, and immediately felt that they had come to mix up, thinking that they knew that their strength in this infancy would not cause any substantial damage to the crystal big rock snake in front of them at all, but the two of them still stood behind Mu Chen, and they released the long-range spells they had learned, and did their best to interfere with the crystal big rock snake.

I saw that the golden dragon summoned by Mu Chen was fighting happily with the crystal big rock snake, and the crystal big rock snake that was firmly entangled by the golden dragon had no time to care about the spells released by Tan Wan and Yang Yilan in the distance, and he didn't feel the sharp sword qi released by Mu Chen on the side at all.

It seems that the three of Mu Chen have won one thing, but they are just ......

Since it was a chance, it was impossible for the three of them to successfully defeat this crystal rock snake so easily.

I saw that the sharp sword qi released by Mu Chen slashed towards the crystal big rock snake, and the golden dragon also hurriedly twisted his body, successfully avoiding the sword qi that slashed towards the crystal big rock snake, so that he would not accidentally hurt himself.

But......

The sword qi that looked so sharp shattered when it hit the crystal great rock snake, and it didn't leave a trace on the crystal big rock snake's body.

Sure enough, none of the creatures that can appear in these places as a chance will be easy to deal with.

Seeing that his sword qi could not have the slightest effect on the crystal big rock snake, Mu Chen was also slightly surprised.

Mu Chen originally wanted to use this sword qi to test the defense of the crystal big rock snake in front of him first.

If this sword qi can leave a relatively deep scratch on the body of the crystal great rock snake, then with Mu Chen's current spiritual power background, if he pushes the fourth seal on the wooden sword twice in a row, he should be able to easily kill the crystal big rock snake in front of him.

It's just that now it seems that I was still too naïve.

Seeing that this sword qi hit the body of the crystal great rock snake, and there was no mark left, Mu Chen couldn't judge the body defense of the crystal big rock snake in front of him at all.

And if he couldn't judge the defense of the crystal big rock snake in front of him, Mu Chen wouldn't dare to easily urge the fourth seal on the wooden sword, after all, the crystal big rock snake in front of him was also the strength of the distraction period, and it was if he consumed the spiritual power in one go.

So......

Not to mention whether there is any hope of defeating this crystal rock snake, it is difficult to say whether the three of them will be slaughtered by this crystal rock snake.

After all, the average level of cultivation of Mu Chen, Tan Wan and Yang Yilan is only in the late Yuan Infant stage.

For the crystal big rock snake with the strength of this distraction period in front of him, there is a whole out-of-body period!

With no means left, it is undoubtedly wishful thinking to defeat a crystal great rock snake with the strength of a distraction period.

Moreover, Mu Chen could also detect that the attack of this crystal big rock snake was not strong, because the tail swing of the crystal big rock snake just now was easily resisted by the golden dragon he had summoned, so the first seal on his wooden sword, the 'blood wave', was also useless.

After all, the essence of the first seal on his wooden sword, the 'Blood Wave', is just a rebound, but the attack of this crystal big rock snake is so weak, but its defense is quite high, and urging the first seal on this wooden sword is just a waste of his spiritual power for no reason.

However, what else can be done to defeat the crystal rock snake in front of him?

Mu Chen didn't know either.

His own golden dragon was entangled with the crystal rock snake again, and after fighting with the crystal rock snake for so long, his golden dragon showed no signs of damage, which was enough to show how weak the attack of the crystal rock snake in front of him was.

After thinking about it for a long time, Mu Chen also thought of only one way.

That is to urge the fourth seal on his wooden sword, coupled with the breath of his own Chaos Dragon bloodline, to see if he can break through the defense of this crystal rock snake.

If this is the case, it will not be able to break through the defense of the crystal rock snake, then Mu Chen feels that instead of fighting with the big guy in front of him and wasting his spiritual power, it is better to transfer the target and see if he can break the sealed entrance behind.

When Mu Chen thought of these methods, Tan Wan and Yang Yilan naturally sensed the weakness of the attack of the crystal big rock snake, and they didn't release the spell from a distance, they all showed their weapons and rushed up directly, and they were entangled with the crystal big rock snake.

But it didn't work in the slightest......

decided on the next attack, and Mu Chen also called back Tan Wan and Yang Yilan to avoid not injuring the crystal big rock snake at that time, and indeed beat his teammates half-crippled.

After Tan Wan and Yang Yilan both returned to his side, Mu Chen also slowly raised his wooden sword and aimed the blade of the wooden sword at the crystal big rock snake.

The fourth seal on the wooden sword flickered faintly, and Mu Chen's momentum was also constantly improving. In his body, the breath of the Chaos Dragon's bloodline was also continuously injected into the wooden sword by Mu Chen.

The purple thunder that danced on the blade of the wooden sword also faintly turned dark red after being injected with the breath of the Chaos Dragon's bloodline by Mu Chen.

Beside Mu Chen, Tan Wan and Yang Yilan also felt this terrifying aura, feeling that if Mu Chen stopped this thunder from hitting him, then he might not even have scum left......
