Chapter 3447

Energy rumbled as the power of lightning surged. One after another, three-star exotic beasts were easily killed by Zi Chen.

Zi Chen hadn't even used his demonic blade yet.

Compared to the powerful Zi Chen, Guan Zhen and the others seemed to be having a hard time.

This was a test between people of the same level.

It was inevitable that everyone would find it strenuous.

The tenth three-star exotic beast appeared in front of Zi Chen. Its limbs, head, and back were all shining with lightning, indicating that it had a lot of Holy Thunder Demon Bones.

Whoosh!

It charged at Zi Chen at an extremely fast speed.

"There's really a speed boost."

Seeing this, Zi Chen's eyes shone. "However, your level is too low."

Zi Chen's figure flashed as he used the Nine Flashes of Holy Thunder. While dodging his opponent's attack, he threw a punch downwards.

The punch whistled down, distorting the surrounding space.

Boom!

The three-star exotic beast's head was hit by Zi Chen's punch, and its body immediately fell down.

However, it didn't die, because the Holy Thunder Demon Bone in its head neutralized most of the power of the punch.

Zi Chen was a little surprised. He descended and threw out another punch.

His speed had an absolute advantage. He wasn't afraid of anyone of the same level.

Rumbling sounds rang out continuously. Powerful forces shook continuously, forming countless ripples that spread out.

After a dozen or so punches, Zi Chen finally shattered his opponent's soul bit by bit.

As the three-star exotic beast died, its body disappeared.

This was a great loss for Zi Chen, because he didn't get a single demonic bone after killing ten exotic beasts in a row.

However, at this moment, the unchanging scene changed.

The space in front of him distorted, and a passage appeared. There were stairs that extended into the distance in the passage.

Zi Chen walked towards the stairs curiously.

The stairs were in the void. Zi Chen stepped on the stairs as he walked forward.

Every step he took would cause a ripple on the stairs, and lightning would scatter in all directions.

Zi Chen didn't know why, but he still spread out his spiritual senses and didn't find any danger.

After climbing about a hundred steps, Zi Chen saw a huge castle appear above his head.

The gate of the castle was closed, and Zi Chen walked forward.

Just as he reached the entrance, a ray of light descended and turned into a person.

Zi Chen's expression changed. He took a few steps back and stared at the other party.

"Those who trespass into the Thunder Fortress shall die!"

The other party's voice was cold, and his eyes were filled with cold killing intent. An aura that belonged to a Four Star Saint Spirit gushed out from his body.

"Thunder Fortress?"

Hearing this name, Zi Chen was a little surprised, and his emotions fluctuated a lot.

Was this a Thunder Castle?

At this moment, the other party threw a punch forward.

As he punched forward, his opponent's palm lit up. During that time, one could faintly see the bones of his hand made of lightning.

Seeing this scene, Zi Chen's expression changed again. He cried out involuntarily, "Holy Thunder Demon Bone!"

The fist was already nearing, and it contained an extremely violent force. It seemed like it was going to drown Zi Chen.

On Zi Chen's right hand, the Demon Bone was activated. He then used his strongest strength to collide with the incoming fist.

At this moment, Zi Chen was extremely excited.

This unknown Four Star Saint Spirit had indirectly proved to him that humans could also condense the Holy Thunder Demon Bone.

When the two fists met, a loud boom was heard. Zi Chen only felt a strong force entering his body, and his body was pushed back.

He was even more excited. The other party only had one Holy Thunder Demon Bone, and he was already so powerful.

In the next moment, Zi Chen went forward again. He used all three of his powers. At the same time, he also used the Demon Bone Palm and the Holy Thunder Explosion.

The second fist collided. Accompanied by a deafening sound, the Four Star Saint Spirit with the Holy Thunder Demon Bone flew back and smashed into the door of the main hall.

Blood stained the door red. His body slowly fell down and his aura dissipated.

With one punch, Zi Chen destroyed a Four Star Saint with the Holy Thunder Demon Bone.

Before Zi Chen could carefully examine the other party's Holy Thunder Demon Bone, he saw the other party's body disappear into thin air, turning into countless light spots.

These light spots were all lightning energy. They looked very pure, like fireflies, and they went straight for Zi Chen.

In the next moment, they merged into Zi Chen's body.

Zi Chen was shocked. He thought that this was some kind of powerful attack. However, he soon realized that after these light spots entered his body, they divided into two parts. One part went into Abdomen through his meridians, and the other part went into his body.

This energy was very pure and extremely powerful. It was even more powerful than the energy of a Saint Crystal obtained from killing a Four Star Exotic Beast.

Moreover, it didn't need to be deliberately refined. It could quickly strengthen his body.

Zi Chen looked at the closed door in front of him. His eyes were shining.

If there were more of such existences behind this door, then this place would be a place of opportunity for Zi Chen.

Zi Chen's eyes became fervent as he walked forward.

The blood on the door had disappeared. He exerted force with both hands, trying to push open the door of the castle.

It was very heavy, but it wasn't unshakable.

Using three stars and three powers, the door slowly opened.

Countless lightning bolts filled his vision. It was as if the door had been sealed for many years. An ancient aura rushed towards him.

There was no danger, only countless lightning bolts. Zi Chen took a long time to get used to it.

He stepped through the door.

The door that had just opened behind him closed by itself.

In front of him, there was still a staircase, which was divided into several stages.

Zi Chen walked forward.

After walking a hundred feet, a lightning bolt descended from the sky and turned into a person.

"Trespassers of the Thunder Fortress, die!"

It was still the same cold voice as before. After saying that, he started to attack.

This time, Zi Chen noticed that the other party had the Holy Thunder Demon Bone on both of his hands.

The two of them clashed several times. This time, Zi Chen didn't manage to kill the other party. They were evenly matched.

Sensing the strength of the other party, Zi Chen frowned slightly.

The other party's fists attacked again. This time, it was two fists, which completely blocked Zi Chen's path.

Cold light flashed in his eyes. Zi Chen used the Nine Flash of the Holy Thunder. His body flashed a few times and dodged the other party's attack.

At the same time, he unsheathed the Demon Blade and slashed the other party's neck from the side.

Obviously, the other party didn't have an advantage in speed because he only had the hand bones.

The other party's body was split into two. As soon as it fell to the ground, it turned into countless light spots and entered Zi Chen's body.

This time, the light spots were much denser than before.

After absorbing the energy, Zi Chen's cultivation improved a little. This made him very happy, as if he saw the hope of breaking through.

Because there was still a long way to go.

After walking up the stairs of the second section, another person descended from the sky. This time, the other party had the Holy Thunder Demon Bone on all parts of his body.
