"This aura is almost comparable to an ordinary Mingyang Realm powerhouse, and now I am definitely not his opponent. Zhang Yu thought secretly in his heart.

Zhang Yu knew that the accumulation of this black python before the tribulation must be extremely strong, otherwise it would be impossible to trigger such a large-scale vision of heaven and earth.

And as long as this black giant python successfully transforms into the body of a dragon, it will immediately advance to become a royal-level demon beast, and even among the emperor-level demon beasts, it is said to belong to the existence of a hegemon.

If Zhang Yu wanted to kill the black python, there was only one chance, and that was within an hour after he survived the Heavenly Tribulation.

Because for demon beasts, they will inevitably be severely injured after successfully surviving the Heavenly Tribulation, and even if they are rewarded by Heaven and Earth with that kind of strange energy, it will take an hour or so to recover as before, and this time is the most dangerous period after their tribulation.

Therefore, the general demon beast is either looking for an inaccessible place, or it is guarded by other demon clan powerhouses, and there are few people who are alone.

This Mangdang Mountain stretches for thousands of miles, which sounds not small, but among all the mountain ranges in Zhongzhou, it is only the kind of mountain range with the lowest ranking, and the strongest demon beast is only a general, and it is precisely because of this that Zhang Yu will be so unscrupulous in the mountain range to practice with various demon beasts, without worrying about arousing the anger of those strongest demon beast kings.

He didn't expect that there was a black python in this mountain range, otherwise he would definitely restrain a lot.

"I'll lurk here first, and wait until the moment when this black python successfully turns into the weakest Jiao and suddenly strikes and gives him a fatal blow. Zhang Yu thought secretly in his heart, and he was determined to operate, and there was no trace of breath leaking from his body.

When Zhang Yu was thinking about how to kill the black python in his heart, the black python's transformation into a heavenly tribulation also began to come.

In the void, endless thunder converged into a huge oval-shaped thunder pool, and the purple-black thunder kept flickering with a world-destroying luster, which seemed to be likely to pour down at any time, drowning and devouring the black python that tried to change its life against the sky.

The dark clouds were rolling, the power of thunder was gathering more and more, and the coercion in the space was becoming more and more terrifying, but the black python was unaware, only to see him suddenly raise his head to the sky and roar, as if he was deliberately provoking.

The body of the huge demon beast writhed, containing a heart-palpitating destructive power.

"Peng!"

The python's tail slammed into the ground, like a meteorite falling, and the earth shook in an instant, and the earth cracked into countless criss-crossing cracks.

The terrifying energy ripples swept out, and the white bones that were originally piled up on the ground instantly turned into powder, and the black python opened its bloody mouth and sucked it hard, and the white powder was completely sucked into his mouth by the black python, and his body squirmed, and his breath became stronger.

Especially at the top of his forehead, a large round bulge gradually protruded, as if something was ready to break out at any moment.

Zhang Yu knew that when the black python successfully survived the catastrophe, the big bulge would completely transform into a dragon horn, and that also meant that the black python would fade away from the python body and achieve the body of a half-dragon.

"Click!"

A deafening explosion suddenly sounded in the sky, and then a purple-black thunderbolt the size of a bucket fell from the sky and slashed down towards the black python.

The power of thunder is masculine to strong, even a trace of power that escapes slightly is enough to penetrate the void, and it has a strong suppressive effect on demon beasts.

But at the moment of splitting, the huge tail of the black python suddenly twisted together, spinning like a black giant spear and blasting towards the thunder.

"Boom!"

The terrifying power exploded, and the first thunder was directly smashed by the giant python formed by the black python's tail, but the black python was obviously not as easy as imagined, the tail was dripping with blood, and many places were even more scorched.

When the second thunder was brewing, the incomparably strong blood qi in the black python's body was also surging rapidly, and the scars on his tail actually recovered at a speed visible to the naked eye, and in the blink of an eye, they had recovered as before.

If it weren't for the shattered blood-stained scales on the ground, you wouldn't have imagined that he had successfully survived the first thunder force.

Zhang Yu, who was hiding in the dark and peeping, also gasped, and also had a new judgment on the strength of the black python, at least his physical recovery power was several points worse than that of the black python.

"I'm afraid that it will be a vicious battle at that time. Zhang Yu muttered softly.

Although this first thunderstorm was the weakest, it was beyond Zhang Yu's expectation that the black python could pass through it so easily.

"Click!" At this moment, a second thunderbolt descended.

However, the second thunder was much more powerful than the first, and it was smashed to pieces by the black python in the same furious way.

Next, the third and fourth thunderstorms also failed to hit the black python hard, and were destroyed by him one by one.

"Boom. ”

The thunder roared in the void, as if expressing anger at the black python. And the power of thunder in the thunder pool continued to brew, but it never descended.

As we all know, if it is the simplest Forty-Nine Heavenly Tribulation, the Black Python has successfully crossed the Tribulation at this time, but it is obvious that this is a more powerful Heavenly Tribulation than the Forty-Nine Heavenly Tribulation.

And from the Five or Nine Heavenly Tribulation upwards, the power of each Tribulation Thunder has a qualitative leap, and that kind of destructive power is enough to make anyone frightened.

The black python also seemed to understand the horror of this thunderstorm, and its body gradually tensed, and a touch of attention flashed in the cold snake pupils.

"Click!"

The fifth thunderbolt instantly pierced the void, and the huge sound seemed to be arrogantly announcing its arrival, and half of the sky turned black and purple at this moment.

Feeling the terrifying and destructive power contained in the thunderstorm, the black python roared angrily in the sky, and its body soared straight into the sky, colliding with the thunder in mid-air.

The terrifying arc of thunder shot out in all directions, and the nearest mountain peak near this place was instantly full of holes, and then it shattered, and the boulder rolled down, almost hitting Zhang Yu.

The bulges around the valley were all flattened, and the energy storm swept away, leaving no grass and rippling dust.

"Boom!"

The black python carried the scarred python body from the sky and fell to the ground, this time his injuries were quite serious, especially the cracked flesh everywhere, there was a trace of purple electric arc raging, crazy erosion and destruction of his flesh......

It was as if countless people were slashing him with sharp blades, and the intense pain caused the black python to roll on the ground, trying to expel the lightning arcs that had burrowed into his body.

However, these lightning arcs stuck to his body like maggots on the tarsal bones, and the energy would not disappear at all until it was exhausted.

"Roar!" a tyrannical roar came from the black python's mouth, and a mouthful of blood-colored mist suddenly erupted from his mouth, and those blood-colored fogs quickly spread and stained his body.

After having these blood-colored mist, those wounds that were shattered by the thunder actually healed quickly, and even many of the thunder forces that were rioting in his body encountered these blood-colored mist, like cold ice meeting fire, and disappeared.

However, this time, it can be clearly felt that the aura on the black python's body after spitting out this mouthful of blood mist is also a lot weaker.

Before the black python could fully recover, the sixth thunderbolt in the sky that roared like a thunder god fell again.

This time, the black python did not continue to be strong, but quickly wrapped its body in circles, and in the blink of an eye, the entire black python turned into a mountain of meat.

However, that tribulation thunder was not weakened in the slightest because of the change in the black python's figure, and it was even more terrifying than the fifth tribulation thunder.

The python tail collided with the sixth thunderstorm first, and the thunder directly broke the python's tail with a devastating momentum, and then a large area of black scale armor was shattered, and the python's body was even more bloody and miserable.

Even the white bones in the giant python demon body were already clearly visible.

The sixth thunder raged for a full minute before it dissipated unwillingly, although it was covered with bruises, but the black python still managed to survive the sixth thunderstorm.

The originally violent Void Thunder Pool suddenly became calm, but those who had seen the Thunder Tribulation knew that the most terrifying last Tribulation Thunder was about to come.

A large piece of flesh and blood on the body of the black python was peeled alive, and at a glance, it seemed that only some fascia were connected, and it seemed that it would break at any time, which looked extremely terrifying.

However, at this time, the black python has no scruples about these, as long as he survives the last thunderstorm, then he can turn into a dragon that calls the wind and rain, and from then on he will roar into the sky, and if he can't get through it, he will turn into ashes under this thunderstorm, and he will not leave even a trace.

"Click!"

Suddenly, the heavenly dome seemed to tremble violently, the Void Thunder Pool suddenly overturned, and the infinite thunder and lightning burst out with a ray of destruction, surging towards the black giant python, as if intending to destroy this alien species that defied the Heavenly Dao into nothingness.

Feeling the destructive power contained in the last thunderstorm, Zhang Yu's heart was also terrified, and he secretly said that the sky was unpredictable.

"Roar!"

The black python knew that this last thunderstorm was both a catastrophe and a creation, and in the roar, an oval-shaped black crystal shot out from a mouth, colliding with the seventh thunder that destroyed the world.

Then the body of the black python also rose to the sky, like a warrior who was not afraid of death, and rushed towards the thunder with his head.

In the sound of explosions, flesh and blood flew sideways, but before it landed, it was incinerated into ashes by the power of thunder free in the void, and the back half of the black python's body was directly shattered, and the front half of the body was also pierced by the power of thunder Countless blood holes, and even the bones comparable to gold and stone were shattered and broken.

The black dragon suffered a heavy blow, but the pair of scarlet snake eyes flashed with excitement.

He knew that soon this seventh tribulation thunder would dissipate, and his demon crystal would also complete the thunder quenching and turn into a dragon ball, and he would be reborn.

Just as he was immersed in endless joy, he suddenly felt a cold killing intent descending from the sky.
