Chapter 691 The Mark Of The Seal, The Black Destruction Serpent Dragon Appears

On a stone platform in the dark swamp.

Ye Feng was sitting on it.

He closed his eyes and activated the [Dragon Vein Technique]. The surrounding spiritual energy swarmed into his body.

With the infusion of spiritual energy, Ye Feng's skin started to turn green. He was like an ancient beast that was letting out deafening roars.

"Hmm, what's this?"

Suddenly, Ye Feng opened his eyes and looked at his right arm.

A mysterious rune appeared on his right arm.

"This is a sealing rune. This sealing rune can suppress the bloodline power of demonic creatures."

"The bloodline power of the Black Fiend Great Demon Emperor is actually sealed by this seal pattern!"

"However, this is only temporary..."

Ye Feng's eyes shone with a bright light.

The blood of the Black Fiend Great Demon Emperor was the blood left by a great sovereign of the Demon race after his death. It contained the will of a venerable sovereign of the Demon race.

Although the blood of Black Fiend Great Demon Emperor was sealed, there was still a powerful will within the drop of demonic blood.

This kind of will was unwilling to be left out. It was restless and tried to break the seal!

Thus, what Ye Feng needed to do was to let the sealing runes grow and eventually seal the demonic blood completely, preventing it from stirring up any more waves.

"Which Demon Emperor did the blood of the Black Fiend Great Demon Emperor come from?"

Ye Feng furrowed his brows and muttered.

If it was just an ordinary Beyond A grade Demon, it would be impossible for him to possess such a heaven-defying divine item like the blood of the Black Fiend Great Demon Emperor.

This drop of blood from the Black Fiend Great Demon Emperor was probably related to a certain venerable sovereign of the Demon race.

For now, Ye Feng could not afford to offend an existence at this level.

At this stage, Ye Feng could only deal with Beyond A grade realm experts.

Furthermore, there were too few Beyond A grade realm symbiotic demons, they did not dare to venture deep into this place, and Ye Feng did not dare to take the risk!

"Beyond A grade realm symbiotic demons, although doesn't pose a threat to me, is extremely dangerous to my family and friends back home!"

"Now, it's time for me to explore the location of the Demonic Spring."

Ye Feng stood up. His eyes were as sharp as a knife.

He was going to find that Black Destruction Serpent Dragon!

In Ye Feng's eyes, this Black Destruction Serpent Dragon was a moving Demonic Spring. Its blood could nourish the Demonic Spring, allowing it to recover its vitality.

"Let's go!"

Ye Feng jumped up and ran away from the corpse of the Black Fiend Great Demon Emperor.

..

"Roar..."

The Black Destruction Serpent Dragon sat on the peak of a tall mountain, and it let out a deep dragon roar. All the creatures in the surroundings fell to the ground and shivered. They didn't even have the courage to raise their heads.

The Black Destruction Serpent Dragon's strength was terrifying. At Beyond A grade, it already had the strength of an S grade.

Moreover, it could also summon a group of Demon soldiers and make them listen to its command.

There were more than 200 soldiers in this army, all of whom had the strength of A+ grade.

"Roar--"

The Black Destruction Serpent Dragon opened its mouth and howled. Over two hundred Demon soldiers immediately surrounded Ye Feng. They were so dense that they covered the entire sky!

Seeing this, Ye Feng's expression changed.

"Hmph! You're just some small fries! Get lost!"

He shouted coldly and took out a [Ice Arrow].

Chi la!

A terrifying sword light swept out and instantly killed three Demon soldiers. The remaining momentum didn't decrease as it continued to press toward the Black Destruction Serpent Dragon!

The Black Destruction Serpent Dragon roared and spat out a black mist to block the ice arrows.

Its scales had amazing defense, and the ice arrows could not cause it any damage.

"D*mn it!" Ye Feng cursed, his heart filled with depression.

He was at the peak of his strength, but he had to face the Black Destruction Serpent Dragon. Not only was his strength greatly reduced, but he also had to deal with more than 200 of the Black Destruction Serpent Dragon's subordinates.

He continued to use his blade techniques, but these soldiers were not afraid of death. He could not quickly get rid of them. Instead, he had used up half of his spiritual energy.

"If I continue to delay, I won't be able to escape even if I want to when my spiritual energy is exhausted!"

Ye Feng was extremely anxious.

These Demon soldiers were all fearlessly fearless. Even if they knew that they were going to die, they would also charge up and tear at it.

"I don't care. I'll lure it over first and let it fight me one-on-one to distract my attention!"

This crazy thought appeared in Ye Feng's mind.

Since there was no hope of escaping, he would give it a try.

Ye Feng activated the [Ice Arrow]. Sword shadows burst out one after another.

Bang! Bang! Bang...

The power of these ice arrows was extremely shocking, and each strike carried a terrifying destructive power. Once pierced, bones and tendons would be shattered, and blood and flesh would fly everywhere.

In just a few breaths of time, dozens of Demon soldiers under the Black Destruction Serpent Dragon were killed by Ye Feng's ice arrows.

"Roar, roar, roar...!"

The Black Destruction Serpent Dragon's anger was burning. Its roars shook the heavens. Its two huge eyes stared at Ye Feng, and it wanted to skin him alive.

"Evil creature, you're looking for death!"

Ye Feng controlled the ice arrows to kill the Black Destruction Serpent Dragon, while at the same time, he used the [Slime Power] to attack the Black Destruction Serpent Dragon.

Boom!

The Black Destruction Serpent Dragon's body was charred black, and it let out an angry roar.

Ye Feng continued his attack.

Boom...

The Black Destruction Serpent Dragon was covered in injuries.

Not long ago, Ye Feng had used this to kill two of the Black Destruction Serpent Dragon's companions, and now, he wanted to use the same method to kill the Black Destruction Serpent Dragon. This was truly shameless!

The Black Destruction Serpent Dragon was furious and roared, but it didn't have many ways to attack. It could only use the black mist to release poison.

Anything that the black mist touched instantly rotted, melted, or even turned into blood.

Only the Black Destruction Serpent Dragon's skin had extremely high defense. Even if Ye Feng's ice arrows were to land on it, it would be very difficult to break through its defense.

In that case, Ye Feng would not be able to do anything to the Black Destruction Serpent Dragon.

"Roar!"

The Black Destruction Serpent Dragon roared as it swung its tail and smashed it into the ground. Instantly, the ground cracked and rocks rolled.

Ye Feng's body staggered from the impact, and he almost fell to the ground.

"F*ck... It hurts!"

Ye Feng rubbed his butt and stood up. He cursed in his heart: 'This beast's strength is so great! It's like a piece of iron plate!'

"It seems like I won't be able to kill it if I don't use my ultimate skill."

The Black Destruction Serpent Dragon seemed to have sensed that Ye Feng was not someone to be trifled with. Its huge body moved around the forest, avoiding meeting Ye Feng. It was clearly very wary of Ye Feng.

"Hehe, what's the point of hiding? Come out if you have the guts!"

Ye Feng shouted, and he held the Slime Spear.

The Slime Spear was endowed with the power of lightning. The explosive energy contained within was enough to destroy a mountain range. It was extremely powerful!

The Black Destruction Serpent Dragon was surprised.
