With a "ding" sound, a burst of sparks shot out from the black armor of the sandworm, and then Lin Feng swung out a purple sword qi and disappeared.

Only a white mark was left on the sandworm's body, and sure enough, this layer of black armor was extremely hard, and as soon as this giant sandworm appeared, Lin Feng noticed this layer of black hard shell on its body.

Because after it appeared, there was no fluctuation of demonic power on its body, which means that it was not afraid of the extreme spiritual power in this space at all.

But even Lin Feng, a primordial cultivator, didn't dare to use his own body to resist the extreme spiritual power in it, how did it do it as a demon beast with only a seventh-level peak, so it was not difficult to guess that it relied on this thick layer of black armor on its body to resist this harsh environment.

Sure enough, the demon beast that can grow in such a harsh environment is not so easy to deal with, and the seventh-level peak demon beast is equivalent to a monk at the peak of the Yudan period, but looking at it now, the strength shown by this giant sandworm, although it does not reach the strength of the eighth-level transformation demon beast, is much stronger than that of an ordinary Jiedan peak monk.

With a "whoosh", the sandworm took back its tail that had not been successfully attacked just now, and at the same time, its body twisted again, and then Lin Feng felt a powerful fluctuation of demonic power on its body.

Then I saw it have a big mouth, and a yellow ball flashed with spiritual light and smashed towards Lin Feng quickly, spitting out from the giant sandworm air, with a burst of demonic aura, the size of Lin Feng's head is about the same size, but the speed is extremely fast.

Without thinking much about it, he directly placed his Purple Heaven Xuan Dao horizontally in front of him, resisting the raging round ball when it came.

With a "bang", Lin Feng flew out, and at the same time, the mana in his body also shook violently.

Obviously, he had just underestimated the power of this yellow stone ball, and he didn't hold up a strong enough spirit shield, but only used the Purple Sky Xuandao as a means of defense, so he was knocked out at once.

Fortunately, Lin Feng is a Yuanying monk, and he has strong mana on his body, otherwise he will be seriously injured this time, and at the same time, he was also surprised by the ball just now, the power emitted by the ball just now is already close to the power of the early Yuanying monk's blow, and at the same time, it actually has the nature of extreme spiritual power, and the quality of the ball itself is also extremely hard, if it weren't for the fact that the Purple Heaven Xuandao was made of meteorite iron outside the sky, and it was replaced by another magic weapon, I am afraid it would have been shattered.

After hitting Lin Feng, the ball bounced back on its own and returned to the stomach of the giant sandworm.

In fact, it was because Lin Feng didn't know the origin of this ball, so he despised it so much, otherwise it wouldn't have been this result.

This earthy yellow ball is the essence of this yellow sand, which is naturally extremely hard and has the nature of extreme spiritual power.

So how did this ball condense, but this giant sandworm from birth to the present, every time it eats the yellow sand, after digestion, the last trace of the hardest essence left behind is condensed, hundreds of years, this ball has accumulated to the size of Lin Feng's head, because the yellow sand is exposed to extreme spiritual power all the time, over time it has also been contaminated with the breath of extreme spiritual power.

Therefore, the yellow sand essence digested by the giant sandworm naturally retains the essence of extreme spiritual power, although the amount is relatively small each time, but it has been accumulated over hundreds of years, and the power is also extremely great, so Lin Feng suffered a small loss.

The primordial infant in his body spewed out a breath of primordial infant qi against the dantian, and immediately the mana that fluctuated in Lin Feng's body stabilized, and as soon as the mana turned, it recovered as before.

At this time, Lin Feng had already put away even a trace of contempt, and had already regarded the giant sandworm in front of him as his opponent of the same level, the demon beasts that appeared in this realm were so strong, worthy of the name of the Jedi, no wonder the outside world was so dangerous.

The blue light flashed in his hand, and a green and white jade ruler appeared in his hand, and the green jade measuring ruler that had been successfully cultivated by Lin Feng had completely restrained the spiritual light, and the green jade measuring ruler that was taken out now was held in Lin Feng's hand just like an ordinary jade ruler.

But as Lin Feng injected mana into it, a burst of cyan light slowly appeared in the jade ruler, gradually covering the pale golden yellow in the space.

At this time, with Lin Feng as the center, the space within a radius of more than ten zhang was shrouded in a blue light, and then I saw a simple and simple jade ruler flying out of the void, flying a few times in the air, and accurately smashing on the body of the giant sandworm.

With a "hiss", this unusually sharp sound came out of the mouth of the giant sandworm, and it was obviously the extremely painful blow that made it scream.

I saw that the huge body of the giant sandworm writhed violently, and suddenly its tail stirred out of the deep yellow sand again.

A sharp blade shining with black cold light stretched out from the soil again, and slashed towards Lin Feng, Lin Feng, who had already seen the strength of this sandworm, naturally would not let this sharp blade split into himself, otherwise it might be directly split in half.

At this time, the green jade measuring ruler that had struck the blow of the giant sandworm evolved in the air again, turning into a huge jade bridge, and the golden runes on it were still flying.

Lin Feng didn't make any extra moves, and stepped directly on the jade bridge, his body suddenly disappeared in place, and the sharp blade of the giant sandworm slashed directly into the void.

After an instant, Lin Feng's figure reappeared, but it was already behind the head of the giant sandworm, raised a pair of fleshy palms, covered with spiritual power, and violently imprinted them.

There was a loud bang, but it was slapped on the black hard shell, and suddenly the sandworm writhed and screamed violently.

A force of shock rebounded from the black hard shell, sending Lin Feng upside down.

Then I saw that the giant sandworm had already twisted its head, and a pair of blood-red demonic eyes were flowing out of black liquid, but it was caused by Lin Feng's powerful palm.

Although it had an unusually hard hard shell, Lin Feng's powerful spiritual power was also extremely penetrating, and through the black hard shell it went straight to the head of the giant sandworm, instantly beating its head seriously and shedding bloody tears.

At this time, the sandworm that turned its head did not hesitate, and sprayed at its mouth, but it was a rotating yellow ball, carrying a fierce demonic force on the surface, and rushed towards the forest wind in front of it at an extremely fast speed.

Seeing that it was about to smash straight on his body, Lin Feng had already taken precautions, and as soon as he grabbed his hand into the void, a simple long ruler of blue and white jade color was slowly pulled out of the void by him.

With a wave, it accurately hit the yellow ball, and with a "bang", the yellow ball burst open instantly, turning into yellow sand in the sky, and then Lin Feng's other hand raised the sandworm's open mouth, and a purple phantom shot out from the sleeve of the wide green shirt.

A "bang" pierced the giant sandworm's mind.
