Dantian was destroyed, awakening the Dzi Bead!

The demon's scarlet eyes shrank, staring at the charging sword, his heart sank, and a look of determination seemed to flash across his face for a moment.

"Do you think you can kill me with your current strength?"

The sound fell, his eyes widened with anger, his face was ferocious, his teeth were clenched, as if he was suffering from great pain, and the scarlet color began to spread from his eyes.

In an instant, the veins on his entire face were exposed, and scarlet lines criss-crossed and extended toward his body.

At the same time, the aura on his body began to rise, and the black energy began to emit. In the blink of an eye, the pressure on his body was several times stronger than before.

"boom!!"

A powerful aura burst out!

"Before I die, if I can bring you with me, my death will not be considered in vain!"

A low and ferocious sound sounded from the demon's mouth, and his eyes protruded, looking extremely terrifying.

With a wave of his hand, a ball of black energy appeared in front of him, blocking the incoming sword energy.

The sword energy collapsed and disappeared without a trace.

Su Yu stood not far away, with a look of disbelief on his face, staring at the darkened demon in front of him.

His brows were furrowed, his eyes were solemn, and he was shocked.

What method is this?

In the blink of an eye, the strength has doubled several times, which is simply incredible.

Is this a secret technique of the devil?

"What kind of move are you doing? It's so fierce."

A low voice sounded from Su Yu's mouth.

"Jie Jie Jie!"

"I'll let you know before you die."

The demon seemed very proud and spoke with pride.

"This is our devil's unique method. It detonates the Dantian and stores all the spiritual energy in the blood and meridians of the body, gaining powerful strength in a short time!"

"Although it doesn't take long, it's still more than enough to kill a weak person like you."

Having said this, the demon paused for a moment, his face suddenly became a little more serious, his eyes were filled with killing, and his deep voice sounded again.

"Now, you can finally understand!"

As soon as the sound fell, powerful momentum began to gather, countless black energy began to spread, and in the blink of an eye, it had occupied most of the prison!

Turning his palm over, another black energy in the shape of a sword blade appeared in his hand.

The steps moved, the momentum exploded, and the figure disappeared in an instant.

Su Yu's face darkened, obviously he didn't expect that the devil would have such means. It's no wonder that the human race was retreating steadily.

However, in the blink of an eye, the strength has increased several times. Now, even if a warrior at the sixth level of the heavenly realm comes, he will only die.

"Zheng!"

As soon as the spiritual energy moved, the sword blade in his hand trembled slightly, the momentum burst out, and the sword energy climbed up, becoming several times stronger than before.

The figure flickered, without any fear, and rushed towards him.

"boom!"

"boom!"

"boom……"

Waves of crisp sounds resounded, echoing in the prison.

Su Yu's face was calm, and he swung the sword in his hand naturally, flawlessly resisting every attack and counterattacking accurately!

For a moment, they had the upper hand.

The demon's brows were furrowed, his eyes were about to burst, and his expression was extremely ugly. He swung the black energy sword in his hand to the extreme, but still could not gain the upper hand, but was retreating steadily.

He was even almost hit by its sword blade several times and died on the spot!

This made him extremely shocked. Even though he had increased his strength several times, he still couldn't defeat him. Why?

Could it be that he was hiding his strength just now?

This is simply impossible. In his current state, it is extremely unbelievable to be able to exert such strength as before.

Now it is even stronger than before. What kind of monster is this?

"boom!!"

An explosive roar sounded, and the demon took a few steps back and hit the wall again.

The black energy-like sword in his hand broke again and collapsed on the spot.

A hint of fear finally flashed across the demon's pupils, as if he knew that the human in front of him was not something he could defeat.

However, he did not give in.

Turning his palm over, his consciousness controlled all the black gas in the prison, and rushed away like an army pressing down on the enemy.

Su Yu frowned slightly, still not feeling panic at all, and said to himself.

Give it a try, does the pure flames in the Life-killing Tower have the effect of restraining it?

At this point in his thoughts, as soon as his consciousness moved, countless spiritual flames surged out from the jade beads and burned wantonly.

In an instant, the flames occupied half of the prison, fighting against it!

"Jie Jie Jie!"

"My devil's black energy is so powerful, how can the flames drive it away?"

The demon smiled treacherously and spoke jokingly, with a look of disdain in his eyes.

However, the next moment, the smile on his face had stiffened, and his whole person was stunned as if he had been struck by lightning.

His pupils began to dilate, and a look of disbelief spread across his face.

I saw that after the black gas hit the raging flames, it was burned out instantly, and the black gas dissipated on the spot.

This, how is this possible?

My devil's black energy is so powerful, how can it be driven away by the flames?

After being shocked in his heart, the demon stared at the man in the flames.

"You, what exactly are you doing? Lie Yan is definitely not an ordinary Lie Yan!"

At this moment, even he was afraid of the flames.

When Su Yu saw this, he was overjoyed. It was great. The pure flames had an effect on his black energy attack. If he went to the battlefield in the future, he would also have an advantage.

Hearing his ferocious questioning voice, Su Yu did not answer, but murderous intent bloomed in his eyes.

Immediately, with a thought, the flames rushed away like a flood, with turbulent waves.

Countless black energy retreated one after another and disintegrated crazily, with only a few strands left in the blink of an eye.

The entire prison was almost swallowed up by the pure flames, leaving only the devil's body untouched by the flames.

The weak black energy didn't dare to spread, it just hovered around him.

The devil's eyes were full of fear, and his whole body was trembling slightly, and he didn't dare to move for fear of being swallowed by the flames.

He did not expect that the human being in front of him could be beyond the scope of his knowledge again and again.

Both the strength and the fierce flames were beyond his expectation.

"What else do you want to say?"

"Say it and I can make you die happily!"

Su Yu did not kill him immediately because he wanted to know more about the demon.

However, things come true!

"If you want to know something about the devil from me, let me tell you, it's impossible!"

"Even if I die, I won't say a word!"

A ferocious and low voice sounded from the demon's mouth, but his will remained unchanged and he never surrendered.

After finishing speaking, he showed a charming smile.

"Jie Jie Jie!"

When Su Yu heard the words, he didn't say much anymore. As soon as he thought, countless flames came over him and swallowed him up instantly.

"what!"

"what……"

Continuous screams rang out, the demon was swallowed up by the flames, struggled wildly, and finally roared.

"We demons will occupy the heaven sooner or later!"

"And you will become our slaves sooner or later!!"

After he finished speaking, his body fell straight into the flames, and was immediately burned to ashes!
