The demon king a thousand years ago, even if his soul is immortal, would not be too powerful now.

Several lightning flashed by, Cang Li's corpse turned into ashes, and his soul was taken into soul refining by Xu Yan.

"Let's explore the way."

After whispering, Xu Yan activated his spiritual power and controlled Cang Li's soul to penetrate into the stone gate.

There is no cover. The stone gate, which should have been trapped by the formation, has long lost its power and retained some weak aura. It can be opened with the evil energy in the blood of the demon clan. It can be used as effective as other demonic blood and even spiritual power. This is why Cang Li spewed blood to open the door before.

In fact, Cang Li was just a pretentious and wanted to confuse Xu Yan.

In the stone hall, Xu Yan's right eye was shining with white light, and he used the fairy-eyed and ghostly eyes, and surrounded by dragon teeth and tiger bone long swords.

With the invasion of Cangli Soul Refining, another hall appeared in Xu Yan's eyes.

There seemed to be a strong wind surging in the gloomy stone hall. As soon as I passed through the stone gate, Cang Li's soul refining immediately dimmed. With a faint sound of a tiger roar, Cang Li's soul refining suddenly scattered and collapsed, turning into nothingness.

As soon as he stepped back, Xu Yan's right eye suddenly closed.

The soul refining was melted and his spell was broken, but the scene behind the gate had already been seen a little.

"Dry bones..."

Opening his eyes, Xu Yan frowned.

He saw a pair of dead bones sitting cross-legged in the stone chamber behind the door. Among them, there seemed to be a powerful soul, which was the soul that had wiped out Cangli's soul.

After pondering for a moment, Xu Yan's eyes turned cold and raised his hand to emit a spiritual power to Shi Hu on the right.

There was a muffled sound, and the stone door was slowly opened.

After roughly speculating on the power of erasing the soul refining of Cangliu, Xu Yan already knew it. Without hesitation, he stepped directly into the second stone hall.

The stone hall was empty. Except for the ditches that still existed on the ground, there was no stone tiger. A dry bone that was obviously a human body was sitting cross-legged in the center of the stone hall. As the footsteps of a stranger appeared, the dry bone's eyes lit up slightly, and a terrifying pressure appeared at the same time.

Not weaker than the pressure of the great monster, although it is terrible, it cannot stop Xu Yan now.

As he approached the dry bones step by step, Xu Yan's eyebrows became tighter and tighter.

The previous speculation seemed to have an accident. This dry bone is obviously a human race, not a demon king or a big monster. Could it be that the human race strongman, a thousand years ago, died with the demon king's tiger soul?

Crack, Crack!

The bright light in the eyes of Du Jian became brighter and brighter, and a sound of bones actually stood up.

"Don't you, the demon king, feel embarrassed?"

While speaking coldly, Xu Yan pointed at the magic weapon, and the tiger bones and dragon teeth burst out.

roar!!!

The standing dead bones opened their mouths and roared, making a roar of a tiger. The next moment, the dead bones and magic weapons collided with each other.

Hurry!

The seemingly ferocious skeleton was actually smashed into pieces by magic weapons and scattered all over the ground.

The bones were shattered, and as Xu Yan expected, he glared at the left eye and stared at the void above the dry bones.

Inside the left eye with star patterns, a tiger's soul was roaring silently.

The tiger's soul is not big, but its aura is no less than that of a great monster!

The demon king's remnant soul has such strength after a thousand years. If it were other virtual pills, it would definitely be swallowed up by it. Even if the unprepared Nascent Soul comes here, it will be easy to die.

The tiger soul entrenched in the dead bones of the human race, with its teeth and claws, was extremely ferocious and wanted to rush to kill it, but could not make any progress. On the tiger soul, the power from Xu Yan's left eye imprisoned it like a deadly shackle.

"Treat!"

With the breath of his left eye, Xu Yan directly used the soul refining method, and his expression was solemn.

After all, it is the residual soul of the demon king, which is much stronger than the great demon soul.

Xu Yan's efforts to sacrifice and refine, while the tiger soul struggled desperately. However, the aura in his left eye was too terrible to control the ghost ghost. Unless it was a complete demon king's soul, it would not be able to escape Xu Yan's confinement.

It took most of the day to keep the continuous roar of tigers in the stone hall before it began to lower and finally disappeared completely.

call……

After wiped the cold sweat from his head, Xu Yan let out a long sigh.

In front of him, a tiger soul was lying in the air, lowering its head and not moving, and a pressure equivalent to a big monster rose and fell from time to time.

"Fortunately, it is the residual soul of the Demon King. If it is complete, it may not be able to become a soul refining."

With his thoughts, the tiger soul moved four claws together and hovered around the master. With Xu Yan's current ability, he could only refine the residual soul of the demon king, but he could not refine the complete demon king spirit. However, he was not afraid of the complete demon king spirit. He had his left eye and magic weapon. Even if this tiger soul was at its peak, he might not be able to hurt Xu Yan.

After all, it is a soul, which is much worse than the real demon king.

Cang Li carefully planned the inheritance of the demon king for many years, and finally became Xu Yan's soul refining. If Cang Li had not died, he would probably have been angry to death.

At this point, two big monsters died in the Canghu lineage, and even the remains of the demon king and the residual soul of the demon king were in Xu Yan's hands, which was almost wiped out.

The residual soul of the demon king and the remains of the demon king are originally one. Xu Yan secretly wondered whether he could use this residual soul of the demon king to control the huge demon king's bones.

After thinking for a while, Xu Yan's eyes moved.

In the bones scattered all over the ground, Xu Yan picked up an extremely old bamboo slip.

This bamboo slip should be the remains of the human race. Xu Yan looked familiar and suddenly remembered the bamboo slip he got from Chi Yuan.

Taking out two and a half pieces of ancient bamboo slips, Xu Yan immediately smiled bitterly, clasped his fists to the bones scattered all over the ground, and said apologetically: "It turns out that it is the remains of the great scholar of ancient cultivators. The boy is rash and ruined your true body."

Even his life was gone, so the ancient cultivator would not blame him. Xu Yan smiled awkwardly, sat cross-legged, and watched the second bamboo slip left by the ancient cultivator.

"Even if the sky is high, there is an end. If you cannot become a golden elixir, you can only practice the Nascent Soul. If the Nascent Soul is not true, you will not break the mirror..."

The words on the bamboo slips are very old and very vague. Xu Yan recognized them very slowly and looked at them word by word.

"Although the Nascent Soul reaches its peak, its defects are still the same, and it can become a divine pattern. However, what's the use of the divine pattern?"

"Flying in the sky is no match for the wind of the sky, entering the earth, blocking it from lava. Although the sky and the earth are big, they are like cages."

"Now we are about to die. With the peak of the fake baby, we gather the power of the formation, and fight with the demon king of the tiger clan in Tianbei, destroy his body and trap his soul."

"I am about to die, and even if I kill the demon king, I will not be liberated. The regrets in my heart will be left forever, and I will leave a map of formation, hoping to benefit the human race."

"Although there are names and names, it is useless to mention them. I envy the thunder that can break through the sky."

"In the name of thunder, to prove the way of a monk, it is not that I lack talent, but that heaven and earth trap me..."

Heaven and earth trap me...

The intermittent whispers became heavier and heavier. The feat of slaying the demon king with the peak power of the Nascent Soul was shocking. Unfortunately, the great scholar of ancient cultivating named thunder eventually died in his own formation.

"Chen Lei, Senior Lei..."

A ray of sorrow surges into my heart, and the sorrow that only belongs to the practitioner is vividly remembered in the bamboo slips.

The second bamboo slip by the ancient great scholars recorded some insights and helplessness. At the end of the bamboo slip, there was a complex array diagram. Xu Yan looked at him and his heart couldn't help but jump.

The way of formation can be big or small. The big ones are shocking the earth, and the small ones are miniaturely hidden. The formation left by the cultivator thunder is extremely complex, and it must have reached the peak of the formation, but its name is as simple as two words.

Kill the demon!
