The pitch-black energy ball contained super dark energy, and it shot towards the Hell Demon Dragon like a cannonball, and the speed was as fast as a flying feather meteor, and it was impossible to dodge.

The Hell Demon Dragon also seemed to sense the danger, and the four thick dragon claws quickly poked out, grabbing the magic ball in front of them.

The magic ball slammed into the four dragon claws, making a screeching grinding sound, and the terrifying friction force scraped a large piece of the scales of the Hell Demon Dragon, and the four dragon claws were already dripping with blood in a blink of an eye, and Bai Sensen's bones were exposed.

But the power of the Hell Demon Dragon is incredibly strong, and it has stubbornly resisted the condensed magic orb, and even continues to infuse dark energy into it, and there is a tendency to control the magic orb.

Su Yu didn't allow him to succeed, so he took this opportunity to jump up, and crossed to the top of the Hell Demon Dragon's head in one step, holding the invisible dimensional blade with both hands, the head of the knife went down, dragging the long knife, and slashed towards the skull of the Hell Demon Dragon.

The six dragon claws on the shoulders of the Hell Demon Dragon grabbed upward, as if six demon hands from Hell had a devastating power, two crossed to block the long knife, and the other four slammed into Su Yu's back one after another.

But in the face of the bombardment of these four dragon claws, Su Yu didn't even shake it, his body shape did not change at all, and he still rushed forward, and the dimensional blade dragged in his hand slashed fiercely on the two dragon claws below.

"Again and ...... at a time"

The knife went down, making a piercing grinding sound, splashing a series of sparks.

And on the two dragon claws, only a blood mark was left, scraping off a large scale, and not even the phalanges were cut.

Seeing such a situation, Su Yu couldn't help but be surprised, when the fatal blow broke out before, the dragon claws that could be cut off with only three billion six billion attacks, and now his own attacks have reached nine and six billion, so he can't help this pair of dragon claws.

"What's the matter, could it be that this pair of dragon claws is his real palm?" Su Yu looked at the dragon claws below, and the thoughts in his heart rose like lightning.

But just as Su Yu flew over the top of the Hell Demon Dragon, the four dragon claws behind him also kept grabbing behind him, although they were blocked by the Eternal Divine Tree every time, but the dragon claws trembled, but they also kept bombarding like maggots on tarsal bones.

Such a hard resistance to the attack, although it did not cause damage to Su Yu, but it would consume a large amount of energy crystals, Su Yu's current energy crystals are no longer surplus, where can he dare to consume like this.

Just when the four dragon claws bombarded for the third time, Su Yu turned around and slashed horizontally, and a touch of sword light slashed out like a match, directly sweeping the four dragon claws in front of him.

"Again and ...... at a time"

Another series of sparks rose, and the four dragon claws retreated in unison, and a row of dragon scales was scraped off their wrists, leaving even a blood mark, but they still did not cut off the dragon claws.

Su Yu could only float back, and at the same time he was a little puzzled, his attack just now was not as good as being able to cut off the dragon claws now, but now it can't, I really don't know what is going on with this Hell Demon Dragon.

And the Hell Demon Dragon had already controlled the condensed magic ball at this moment, roared furiously, and its body spun half a circle violently, and then the four dragon claws dragged the highly condensed magic ball and rushed towards Su Yu frantically.

"Bang Bang ......"

The Hell Demon Dragon ran furiously on the ground, like a super-high-speed tank, and instantly rushed to Su Yu's face, and then grabbed the magic ball and blasted at Su Yu.

Su Yu just wanted to fight back, but found that the Hell Demon Dragon had already arrived, and the dark magic ball that had been blasted out before was even more head-on at an unparalleled speed, which was definitely more than a thousand times the speed of sound.

Even if Su Yu could react, his body couldn't keep up with this speed, not to mention that Su Yu was in mid-air at this time, and he had nowhere to use his strength to tease, so he could only let this magic ball hit his chest.

This blow was as heavy as a mountain, and it hit Su Yu's body, making a muffled sound, and even the Abyss Demon Armor on his body was dented. This Abyss Demon Armor was originally a ninth-order legendary-level magic equipment, derived from the Abyss Demon, with nearly 70 million defenses. But at this moment, it became more fragile than paper, and it suddenly sank in, and even a large hole appeared in the center of the pit.

Su Yu's chest was also slammed with a strong blow, and the Eternal Divine Tree burst out violently, and a black energy pushed Su Yu away from the magic ball, and the whole person actually retreated in the air.

Moreover, the energy crystals in his body were also burning rapidly, consuming millions of energy crystals in every instant, and one second was ten million, which simply made Su Yu feel a burst of urgency.

You must know that Su Yu has a total of 700 million energy crystals on his body, and 30 million were consumed when he turned on the Tianlong Lightning just now, and after a few more attacks, it was already 100 million energy crystals, if he continued to fight like this, Su Yu's energy crystals would also be exhausted.

Once there is no energy crystal, the Heavenly Dragon Lightning will not be able to continue to maintain, and then Su Yu will only be able to hug his head in front of the Hell Demon Dragon.

Seeing that the energy crystal was being rapidly consumed, Su Yu didn't dare to hesitate, and swung his knife forward, slashing the magic ball in the hands of the Hell Demon Dragon with a world-destroying slash.

But the Hell Demon Dragon also seemed to know what Su Yu wanted to do, one dragon claw grabbed it forward, and the other three dragon claws were protecting the magic ball and retracted. This Hell Demon Dragon has found the weapon in his hand, where is he willing to be destroyed by Su Yu like this, he must definitely make good use of it.

Su Yu slashed at the dragon claw of the Hell Demon Dragon, this time the knife marks were deeper, and even the arm bones could be seen, but it was the bones of Bai Sensen.

"Roaring ......"

The Hell Demon Dragon roared furiously, and the moment it was slashed, countless black vine branches grew from the wound on his arm, winding towards Su Yu like a poisonous snake.

As soon as these rattan branches approached, Su Yu felt a burning of his skin, and black marks actually appeared on his hands, and when he looked closely, his skin was burned.

"What kind of magic is this, that can actually penetrate the defenses of the Eternal Divine Tree?" Su Yu was taken aback and flew back.

But those vine branches followed closely like poisonous snakes, and the speed was not slow at all, and they continued to branch and grow in mid-air, forming a huge wall at once, enveloping Su Yu.

"Hahaha, this is the most vicious black devil vine, and the poisonous fire on it can ignore all defenses and directly incinerate your body and burn you into a piece of charcoal!" The Smug Thoughts of the Hell Demon Dragon came over and echoed in mid-air.

"It turned out to be a poisonous fire!" Su Yu was not surprised, smiled, and directly released the poisonous flame.

The poisonous flame erupted in Su Yu's hand, turning into a huge poisonous bee, dragging a long tail flame, and directly pounced on the large net formed by the intertwined black devil vines.
