With the appearance of the Endless Ancestral Fire, the entire sky had become dark, and the energy of the two black-clothed men had also been injected into it, and their faces had turned pale.

Feeling this overwhelming fierce attack, the Poison King and the Old Man with Wind Staff both had a deep shock on their faces.

Under this terrifying aura, they even felt a kind of heartfelt fear, as if the hairs on their bodies had stood on end.

They even had a strange feeling, even if they were spiritual desolate powerhouses, if they were bombarded by this terrifying attack, they would probably be seriously injured or even fall!

Because the old man didn't know the origin of these two people, he suddenly stared at the two men in black with a shocked face.

And although the Poison King knew the forces behind them, he was also terrified in his heart when he saw the earth-shattering methods used by the two of them.

It seems that that force is really mysterious and powerful, and these two people actually played such a trick that shocked him!

And as far as he knew, these two men in black seemed to be far from being at the pinnacle of existence among the forces behind them!

Feeling this oncoming fierce attack, Gu Lin's pupils also suddenly shot out a ray of essence, and his face was full of solemnity, staring at the black flame that roared like a black dragon.

What the hell is this black flame? It has such terrifying power!

However, I also know that now is not the time to hesitate and think at all, the other party can now be said to have taken out the hole card to kill the killer, as long as Gu Lin is a little careless, although now with the help of the power of the blood flame worm, he may be seriously injured or even killed here!

Thinking of this, Gu Lin didn't dare to slack off in the slightest, and the blood-colored flame in his body was also frantically urged to the extreme!

And at this moment, Gu Lin seemed to feel that it was still not enough, after the spirit vein of the undead beast emitted a burst of red light, it suddenly burned a raging flame, Gu Lin had already burned the origin power of the spirit vein, that is to say, he had to use the method of squeezing out the spirit vein to make a desperate fight!

And when Gu Lin fought against the Poison King and the Wind Scepter Old Man just now, although he didn't relax much, he was definitely not forced to this extent.

Although he had also used the power of the Fire of the Undead Beast's Spirit Vein just now, he was only using this blood-red flame as a boost.

As the means of burning the spiritual veins as the last hole card, Gu Lin did not use it from beginning to end.

Because this method can be said to be a desperate fight against the water, a desperate fight to break the kettle!

The power of the spiritual veins is immense, and it is still burning in such a short period of time, and the power that erupts during that time will definitely make people feel terrifying! It will also bring a drastic increase in strength to the caster!

Sure enough, as Gu Lin burned the power of the spiritual vein to the extreme, the originally blood-red flame had turned into a scarlet color, as if with a deadly aura of death!

But it is not difficult to find that the undead beast spirit vein energy in Gu Lin's body is also being squeezed out little by little!

The color of the Origin Power inside also appeared a little sluggish, and it was obvious that after using such a method, Gu Lin was about to completely enter a period of malaise.

However, he also knew that now was not the time to worry about this at all, and gathered all the power of the spirit veins after burning on his body, and the aura on Gu Lin's body suddenly skyrocketed again.

Originally, after using the power of the Blood Flame Worm, Gu Lin's strength had reached the seventh order of the Spirit Desolation, but now with the burning of the Spirit Vein, Gu Lin now definitely has the combat power to break through the Spirit Desolation at the peak of the Spirit Desolation and even break through the Spirit Desolation with one foot!

Feeling this incomparably powerful force, Gu Lin slowly pushed the blood-red flame to the extreme, and then formed a huge blood-colored pillar of light, with a majestic force that made people's hearts palpitate, and slammed into the rolling black flame!

"Boom-"

The two earth-shattering forces finally collided in the exaggerated expressions of everyone, and then the mountains shook in an instant, like the thunder of the nine heavens poured down on the vast land, bringing a burst of uncontrollable turmoil.

At the same time, two flames, one black and one red, began to devour and tear violently, and then collided together and splashed down from mid-air, and each flame that fell seemed to be able to penetrate the human body, and then incinerate the blood into nothingness.

And with the fierce confrontation between these two flames, the underground space has been completely shattered, and the entire medicine tomb seems to be overturned!

Obviously, although this medicine tomb was left by the old man of the miracle medicine, after these unknown years of erosion, the energy in it has long been incomparable to the original, so the degree of solidity is also incomparable!

However, they felt that there seemed to be a vague aura in the underground, and that aura seemed to be guarding the entire medicine tomb, so this medicine tomb did not explode!

Feeling that after the blood-red flame and the black flame clashed, they began to fight each other violently, and Gu Lin was also stunned.

After burning the power of the spiritual vein, his strength has now reached the peak of the spiritual desolation, and even one foot has broken through the spiritual desolation realm, but even so, he still does not have any upper hand under this fight.

And he could feel that the reason why he was holding each other like this now was because his level was stronger than those two men in black, and the black flame seemed to be even more terrifying than the fire of the undead beast spirit vein in his body!

It is no exaggeration to say that if you only judge by the intensity of the flames, the fire of the undead beast spirit vein that Gu Lin unleashed can already be said to be a loss!

The ancestral fire summoned by these two men in black was so terrifying!

However, I also know that these two forces are now in a fierce confrontation, and the power between each other is also devouring, as long as either of the two sides can't hold on, the victory or defeat will definitely be known immediately!

Thinking of this, Gu Lin didn't dare to have the slightest luck, gritted his teeth, the blue tendons on his face burst out, and he also began to squeeze the spiritual energy in his body dry.

And the two men in black also had solemn expressions.

Originally, they thought that after summoning the ancestral fire, it could be said that they would be able to win.

After all, they were extremely aware of the horror of this ancestral fire, and in their cognition, there was no flame that could withstand its attack!

But he didn't expect Gu Lin to persist now, and formed a state of confrontation with them.

This kid is so weird that even they find extremely tricky!

Thinking of this, the power of the two men in black did not have the slightest reservation, and they were all injected into the black flame.

It can be said that as long as one party can't hold on, it will definitely lose irretrievably in an instant!

However, just as the two flames, one black and one red, were about to be decided, the entire medicine tomb suddenly roared, and then a cyan light slowly poured out from the ground.

Then people saw a bronze ancient coffin, flying out like nine heavens and ten earths!

"Burial Heavenly Ancient Coffin!"
