The reason that the Thunder Dominion was named after the word 'Thunder' was because the Thunder Dominion was rich in a type of metal and Thunder Stone. This type of metal and Thunder Stone contained a great amount of thunder and lightning energy.

Because of the existence of the Golden Thunder Stones, there were many cultivators that specialized in the Dao of Metal and Dao of Lightning in the Thunder Dominion. However, after hundreds of thousands of years of mining, the number of Golden Thunder Stones became fewer and fewer.

Currently, the majority of the gold mine was controlled by the Thunder Clan, the absolute overlord of the Thunder Dominion. The power of the Thunder Clan was extremely terrifying. Even the three Divine Kingdoms didn't want to engage in a direct confrontation with them.

As they walked, Ye Chenfeng frowned slightly. He suddenly stopped and looked towards a lush forest to the northwest of the Zhou city, revealing a hint of surprise.

"What's wrong, Brother Morning Wind?"

The Spirit Fish blinked its large eyes and asked softly as it looked at Ye Chenfeng, who had suddenly stopped.

"I felt an interesting person in the mountain forest." The corner of Ye Chenfeng's mouth raised slightly, revealing a faint smile as he spoke.

"Interesting person?" The Spirit Fish tilted its head as it looked at Ye Chenfeng and asked in confusion, "Brother Chen Feng, what do you mean by that?"

"You guys wait here for me, I'll be right back!"

With that, Ye Zichen's body flashed slightly, turning into a shadow and disappeared. He disappeared like a wisp of green smoke into the lush forest in the northwest, then arrived beside a waterfall in the depths of the forest.

And beneath this roaring waterfall, sat a young man with his upper body bare from the impact of the waterfall.

Although this waterfall was dozens of meters tall, the surging waterfall could not harm his body. Streams of sword Qi covered his entire body, continuously crushing the rushing waterfall.

"Jianxin, it really is Jianxin. This young man actually has a Jianxin that I haven't even cultivated!"

Ye Zichen stood by the waterfall quietly and observed the teenager under the waterfall for a while, then revealed a shocked expression.

After confirming over and over again, he was certain that this young man in front of him had successfully cultivated the sword heart that all swordsmen yearned for in their dreams.

Back then, when Ye Zichen was focusing on his swordsmanship, he had also tried to cultivate his sword heart. Once he succeeded in cultivating sword heart, he would have an incomparable talent in the path of the sword.

Unfortunately, Ye Chenfeng cultivated too many complex techniques and was unable to specialize in the sword dao. Thus, he was still unable to cultivate his sword heart.

Fortunately, in the future, due to a stroke of luck, he would be able to cultivate the Sword Soul and walk down another path of the Dao of the Sword.

"Who is it!" Ye Chenfeng's footsteps suddenly alarmed the teenager at the bottom of the waterfall. He suddenly opened his eyes and stared at Ye Chenfeng, who was slowly walking over, then asked vigilantly, "Who are you?"

Ye Zichen smiled as he looked at the young man, whose hair was wet, face was pale, and had a pair of bright eyes that were filled with unyielding determination. He then pointed his finger, and a sharp sword light shot out towards the pale young man.

Being attacked all of a sudden, the pale-faced teenager's expression changed slightly, and he dodged to the side in a sorry state, avoiding the sword light from Ye Chen's finger attack.

When the pale youth tumbled into the surging waterfall, several sword lights shot out from his body, breaking through the surface and attacking Ye Zichen.

"As expected of the person who cultivated Sword Heart. Their attack power is truly extraordinary!"

Although the pale young man was only at the first grade Battle-King, the power of the sword light he shot was amazing. It was almost comparable to the attack of a third grade Battle-Emperor, causing Ye Zichen to reveal his love for him.

"Swoosh swoosh swoosh!"

Streams of sharp sword lights slashed across Ye Chenfeng's body. However, before the pale youth could reveal a happy expression, Ye Chenfeng's body was pierced by the sword lights and became a little blurry.

"Speed Shadow!"

Seeing that his sword light had only pierced through Ye Chenfeng's speed afterimage, the pale youth's expression changed. He leaped into the water, wanting to leave this place as soon as possible.

"Buzz!"

The moment he leaped into the air, a sword ray that exceeded his imagination slashed down. The strength of this sword ray made all the hairs on his body stand up.

He had no doubt that if he were to be struck by this sword ray, he would be hacked into two halves and killed on the spot.

On the verge of death, the pale young man activated all of the potential in his body and twisted his body in an irregular manner in the air, dodging the sword light that Ye Zichen shot down.

"Boom!"

The violently churning Waterfall Lake was attacked by Ye Chen's sword light. It was immediately cut into two halves. Under the terrifying sword light, the water in the waterfall that was split into two was unable to merge together for a long time.

"Bring it all out, if you have the ability to do so!"

Ye Chenfeng looked at the pale young man, who was barely dodging, and said with a faint smile.

"Heavenly Thunder Sword Palm!"

The pale young man clenched his teeth and activated Jianxin's power. He used his hand to control his sword, causing a continuous stream of heavenly lightning sword light to strike towards Ye Zichen with a deafening roar.

Ye Chenfeng did not dodge the attack of the Heavenly Thunder Sword Palm, instead, he continued to attack with his fingers, causing a sharp beam of light to shoot out, breaking the attack of the pale youth one after another.

"Bloodline Ignition!"

The pale youth did not expect Ye Chenfeng to be so powerful that even his most powerful attack could do nothing to him. However, he did not resign himself to fate, nor did he beg for mercy.

However, at the moment he burned his bloodline power, blood suddenly flowed out from the corner of his mouth and his face became even paler. It was obvious that he had suffered a backlash from burning his bloodline power.

"Boom boom boom!"

After using the power of his bloodline to increase his strength, the pale youth continued to send out terrifying streams of Heavenly Thunder Sword Light, which continuously bombarded Ye Chenfeng. He wanted to force Ye Chenfeng back and create a chance for him to escape.

"Mm, the bloodline backlash from my physique has damaged my body!"

Looking at the pale young man, whose body was being devoured by the power of his bloodline, Ye Chenfeng revealed a surprised expression. His body flashed slightly, and like a bolt of lightning, he passed through the incoming lightning sword light and appeared in front of the pale young man.

"Hex!"

Ye Zichen pointed at his chest with his finger, then used the powerful power of his Dao intent to seal his burning bloodline, preventing his soul power, and brought him from midair to the edge of the waterfall pool.
