Just when Su Fan couldn't help but be overjoyed because of the task reward.

Mutation!

Rumble!

There was an earth-shattering noise in Su Fan's body, and his whole body trembled unconsciously!

"What's going on?"

Su Fan's color suddenly changed, he quickly closed his eyes, his consciousness sank into his body, and he began to perceive the situation in his body.

As a result, this perception didn't matter, and it directly stunned him!

I saw that the other nine soul veins surrounding the golden soul vein in his body fell diagonally to the middle like a toppled high-rise building, hitting the surface of the golden soul vein.

And the golden soul vein violently spread out a scene scroll as if destroying the world in the vibration!

In the scene, the stars shattered, the world was destroyed, the space shattered and collapsed, and countless creatures turned into tiny particles of dust in an instant, until they disappeared!

When everything is destroyed, heaven and earth will return to chaos, and there will be a dead silence!

The golden soul veins in Su Fan's body turned into a gray patch in an instant, just like the chaotic and dead world.

At the same time, the other nine soul veins around the gray soul vein shattered one after another, slowly merging into this huge gray soul vein.

The gray soul veins were in turmoil, growing at a speed visible to the naked eye, constantly expanding in all directions.

Su Fan was stunned for a while, the progress of this soul vein expansion was really terrifying, if it continued like this, I am afraid that it would have to be pushed out of the outside of the body.

When the time comes, he may become the first person in history to be strangled to death by the soul vein......

At this moment, a thunderous sound came from the gray soul vein, and then a terrifying suction force emerged from the soul vein, and the soul power in the entire space drilled into Su Fan's body like a wild horse that had broken free.

"It's going to be bad!"

Su Fan slapped his forehead violently, he actually forgot the most serious thing.

At the beginning, the golden soul vein was much smaller than this gray soul vein, and it almost consumed all the pills on Su Fan's body.

Right now, the gray soul vein is still expanding wildly, and with the resources he has now, he really can't feed this foodie!

Now I'm afraid that only the source pool in the Heavenly Demon Tower can satisfy the appetite of this gray soul vein!

Thinking of this, Su Fan did not hesitate, and as soon as his mind moved, he directly flashed into the Heavenly Demon Tower.

As soon as he entered the main hall of the Heavenly Demon Tower, he seemed to sense a higher level of energy, and the gray soul veins in Su Fan's body instantly burst out with stronger suction, and the milky white source qi around him turned into a white storm that swirled violently towards Su Fan!

"Damn! It's horrible!"

Su Fan was caught in these white storms, and his body was almost taken into the air.

"Su Fan, what are you doing, the source qi in the entire hall has run to you!"

The little demon walked out from the back of the main hall, looked at Su Fan, who was surrounded by the source qi storm, and muttered with a dissatisfied expression.

Su Fan comprehended the wind attribute, and quickly adapted to the frenzied source qi storm, only to see that he was full of momentum and fell directly from the air to the ground.

However, because the suction of the soul veins in his body still existed, these source qi storms still gathered around him and kept burrowing into his body.

Su Fan shook his body and complained: "I can't help it, didn't I just unlock the experience, but as soon as I unlocked the ten soul veins, they merged together, not to mention that they became bigger, and they were more edible!"

"Oh...... So that's the case!" The little demon suddenly nodded and smiled: "Your soul vein is about to take shape, and it is currently the most critical step in accumulating soul power, you had better go to the source liquid room to retreat right now to make the final breakthrough!"

"Hmm!" Su Fan responded, "I'll go to retreat now, and we'll talk about other things after the retreat!"

After speaking, Su Fan didn't wait for Xiao Mo's response, and hurriedly walked towards the source liquid room.

As soon as he arrived at the door of the source liquid room, Su Fan's body shook violently again, and the soul veins in his body seemed to turn into a hungry beast, and he had a strong desire for the source pool inside.

"Don't worry, I'll let you eat a big meal right away!"

The will of the soul vein seemed to affect Su Fan, and at this time, he looked at the misty source pool, and a blood-colored light flashed in his eyes.

Thump!

Unlike in the past, when he only stood by the source pool to absorb energy, this time Su Fan jumped directly into the pool.

Bang!

As soon as Su Fan's body fell into the pool, the soul veins in his body emitted a terrifying suction, frantically devouring the source liquid in the origin pool, and a huge whirlpool formed on the calm pool surface in a blink of an eye, and the surrounding pool liquid poured into his body along his pores.

The source liquid entered the body, and the soul veins let out a thunderous roar, absorbing it and quickly compressing it, transforming all these source liquids into drops of colorful soul elements.

Su Fan was slightly shocked when he saw this, his own soul veins were integrated, and even the soul element formed with it was perfectly fused with ten attribute powers.

At this time, Su Fan found that his soul veins seemed to have stopped growing and expanding.

He controlled his consciousness body to the huge gray soul vein, looked up, and suddenly a shocking image was imprinted in his mind.

The top end of this huge gray soul vein stretched into the world of knowing the sea, and the bottom end reached into the dantian that he had not yet opened, like a pillar supporting the gods, supporting his inner world.

"I bet this soul vein of mine is definitely the widest and longest in the world!" Su Fan muttered in his heart.

Su Fan put his consciousness back in place and regained his consciousness, he looked around and found that his feet could actually step on the ground!

"No, this source pool has actually been absorbed by a third!"

Su Fan looked at the smooth stone walls around him, and his heart was shocked.

You know, when he jumped down just now, he was floating on the surface of the pool!

At this time, his soul veins were still absorbing the source liquid around him, but the speed was much slower than before, and Su Fan could feel that his soul veins were about to be filled!

A flash of light flashed in Su Fan's eyes, and he clenched his fists: "Take advantage of now!

It takes 800,000 experience to go from Soul Warrior level 9 to Soul Warrior level 10, and he just killed Soul King and just got an extra 800,000 experience from the task reward.

"System, I'm going to be promoted to the tenth level of the Soul Warrior!"

When the words fell, the 800,000 experience points disappeared, and the soul veins that had fallen silent in Su Fan's body vibrated violently, and ten thousand rays of light shone out from the soul veins.

Under the illumination of the glow, one hundred and eight misty air masses appeared around the soul vein, and these air masses surrounded the soul veins and were ethereal.

"What are these air masses?"

Su Fan was very puzzled in his heart.

"Hey, forget it, if you can't figure it out, you don't want to, anyway, I haven't had any problems practicing now, so be it!"

Su Fan stood up and jumped out of the source pool, at this time he had completely stabilized the realm of the Great Perfection of the Soul Warrior, and his body was full of infinite power!
