"Who the hell is this guy?!"

At this moment, the black snake stared at the oncoming Xia Yun, regretting his choice a little in his heart, he should wait for the arrival of other immortals before making a move.

He's greedy!

Black Snake would never believe that a mere mortal had such a strong power.

Pity......

He didn't have a second choice.

The moment he decided to kill Xia Yun, he was a dead man in Xia Yun's heart.

"Boom!"

With a muffled sound, the whole person of the black snake turned into a body of flames, but it was not red, but as black as ink, and a black snake shadow appeared behind him, and this black snake shadow was the source of his name "Black Snake".

Seeing this, Xia Yun continued to castrate, knowing that the other party had finally moved seriously and used the immortal method, as for what kind of immortal method it was, he really knew.

When he was in Tianshu Palace, Xia Yun had seen this kind of immortal method, called "Dark Snake Fire Source", which was an extremely powerful immortal method, which belonged to the level of earth immortals.

Since the black snake used the immortal method, Xia Yun could only fight with all his strength.

"Roar!"

A dragon roared and fell from the sky.

Thunder and dragons, breaking through the sky.

"Abyss Fighting Spirit?!"

As soon as the black snake saw the Thunder Fighting Dragon, his eyes immediately widened, and he couldn't believe the scene he saw in front of him, but he knew that he was not mistaken, the guy in front of him would actually have this kind of immortal method that had been lost in the fairy world.

"Heavenly Spirit Immortal Gate?"

In an instant, a name that had long been forgotten by the world appeared in the black snake's mind.

"Impossible?!"

Soon, Black Snake denied this conjecture, Xia Yun could not be a disciple from the Heavenly Spirit Immortal Sect.

The Heavenly Spirit Immortal Gate has long ceased to exist.

However......

The immortal method of the Abyss Dou Ling, in the legend, is only available in the Heavenly Spirit Immortal Gate.

"What's going on?!"

Black Snake felt more and more that things were getting a little complicated, especially Xia Yun's background.

The immortal robe thunder light, the weird blood flame, and the abyss fighting spirit are enough to illustrate this point.

However......

Black Snake didn't have time to think too much.

"Roar!"

With a dragon roar, the black snake's heart moved, and the flame black snake behind him rose into the sky and flew towards the Thunder Fighting Dragon.

Although it seemed that the Thunder Fighting Dragon was far several times larger than the Flame Black Snake, it was soon devoured by the Flame Black Snake, who had no power to fight back.

"Poof!"

Xia Yun suddenly spit out a mouthful of blood.

"Devour?!"

Xia Yun instantly understood something, the flame of the black snake had a terrifying devouring rule power, although it was the origin of the fire spirit, it was integrated with other rule powers.

"This man is terrible!"

Xia Yun's evaluation of the black snake in his heart rose to a new level.

At least now, Xia Yun can't do this, he can't integrate the power of other rules into the Thunder Spirit Origin, even if it's the Thunder Rules, he can't do it.

All he could do was how to use the Thunder Spirit Origin.

Xia Yun also knew that he was not a spirit immortal, so he could only do this.

However, Xia Yun knew very well that it was an extremely difficult and dangerous thing to integrate a rule power into the origin power.

Primordial forces are mutually exclusive, and rule forces are no exception, just like fusing two strong magnets together.

However......

Xia Yun didn't just give up.

The Abyss Fighting Spirit was just his attempt to test the black snake's reality.

His real killer move has not yet been shown.

"Huh?"

The black snake saw that Xia Yun was seriously injured, but he still rushed over, and his heart became more vigilant.

At this moment, he no longer regarded Xia Yun as an ordinary mortal.

"Roar!"

There was another dragon groan, and the flaming black snake turned around and flew towards Xia Yun's back.

For his fire spirit origin, the black snake is still very confident.

Among the eight immortal generals who guarded this path to immortals, although he was not the strongest, he could also be ranked in the middle.

No matter how strong Xia Yun is, after all, his body is mortal, and it is impossible to withstand too strong a force.

Obviously, in the eyes of the black snake, Xia Yun showed strength that mortals could not afford, even if he didn't kill Xia Yun, the other party wouldn't live long.

Not to mention anything else, just as the Flame Black Snake devoured the Thunder Fighting Dragon, Xia Yun suffered from the backlash of the Origin Power, and spat blood from his mouth, which showed that the other party could not truly control his own Origin Power.

However, Black Snake wanted to kill Xia Yun with his own hands.

There is no doubt that Xia Yun is a true genius, this, Black Snake does not deny, just a mortal, but he controls the origin of the thunder spirit, which is enough to show that the other party's talent understands, if it were not for the existence of the Immortal Prohibition Order in the Land of the Four Directions, Xia Yun would not have a problem at all becoming an immortal.

"Die!"

Before the words fell, the black snake's flame body suddenly pounced on Xia Yun, forming a flank with the flame black snake, making Xia Yun unable to escape and unstoppable.

Xia Yun saw the seemingly desperate scene, and he still didn't panic at all, since he chose to make a move, he didn't plan to stop, let alone escape.

"Roar!"

Suddenly, a terrifying dragon roar echoed through the void.

"Huh?"

The black snake suddenly raised its head, and those flame eyes erupted with terrifying firelight, giving people an extremely shocking feeling.

"Water Spirit Origin?!"

Once again, the Black Snake couldn't believe his eyes.

At this moment, Xia Yun used the Abyss Fighting Spirit again, but what he summoned was not the Thunder Fighting Dragon, but the Canghai Fighting Dragon.

For the Abyss Fighting Spirit, it is unfortunate that the Black Snake has really studied it, after all, his Dark Snake Fire Source and the Abyss Fighting Spirit have the same effect, both of them use the power of the origin to condense a powerful spirit beast.

The source of the Dark Snake Fire is single, while the Abyss Fighting Spirit is complex.

It's just that he naturally can't find the lost Abyss Fighting Spirit.

In fact, he planned to finish off Xia Yun with his own hands, just to get the Abyss Fighting Spirit, and he didn't want other Town Guardian Immortals to see this scene.

He knew that among the Abyss Fighting Spirits, the strongest state of Dragon Fighting was Canghai Doulong, but he didn't understand how Xia Yun could have two origin powers.

It stands to reason that any immortal has only one origin power, and the reason is very simple, the origin power is repulsive, that is to say, there can be no two origin forces in a person's body.

"What's going on here?!"

Black Snake realized that what happened today was too evil.

However......

The more evil thing is the next scene.

The Canghai Doulong descended from the sky, broke through the sky, and appeared by Xia Yun's side faster than the Black Snake and the Flame Black Snake.

"Boom!"

With a bang, the kilometer-long Canghai Doulong crashed into Xia Yun's body, which was too small to be smaller, and erupted into a terrifying energy storm, sweeping away in all directions.

"This?!"

The black snake was dumbfounded, but he didn't care so much, and immediately retreated.

The Flame Black Snake also soared into the sky, avoiding the terrifying thunderstorm.

"Suicide?"

The black snake stood suspended in the air, looking down at the thunderstorm where Xia Yun was, but he couldn't see Xia Yun's figure.
