However...

At this moment, Lin Fan suddenly sensed the presence of the Immortal Dragon Vein.

"Immortal Dragon Vein?"

Lin Fan was immediately overjoyed: "Could it be that there is an Immortal Dragon Vein in this Six Elements Mountain Range?"

"If there truly is an Immortal Dragon Vein here, it would be a tremendous surprise for me, haha!"

Lin Fan decided to continue forward.

Since there was an Immortal Dragon Vein ahead, Lin Fan naturally wouldn't miss this opportunity.

Lin Fan continued forward...

Roar, roar, roar...

From time to time, Lin Fan heard loud roars.

These were dragon roars!

"This... doesn't seem to be an Immortal Dragon Vein!"

Lin Fan thought to himself: "This seems to be... an actual Dragon Soul!"

"If it really is a Dragon Soul, then I'm in for a huge gain, haha..."

Lin Fan couldn't help but accelerate to his maximum speed, rapidly moving forward.

Meanwhile, as Lin Fan moved quickly ahead, he noticed the power of thunder and lightning became increasingly dense.

Earlier, the Five Elements Power and the power of thunder and lightning were intertwined, but here, the power of thunder and lightning had completely suppressed the Five Elements Power.

In fact, there were no Immortal Beasts here, and even the plants were scarce. The ones present had thunder attributes, and just touching one would make one feel a strong current of thunder and lightning power penetrating the body.

"This is bad!"

At a certain moment, Lin Fan suddenly felt an overwhelming sense of danger engulf him, a massive threat sweeping towards him.

Without hesitation, Lin Fan quickly dodged, activating the Fast Character Technique to leave his position.

As Lin Fan left his spot, a gigantic thunderbolt struck down, landing precisely where Lin Fan was moments ago. It was fortunate that Lin Fan dodged quickly; otherwise, if the lightning had hit Lin Fan, he wouldn't have died but would at least have been seriously injured!

"There's yet another danger here!"

Lin Fan thought to himself: "Moreover, the Five Elements Power is completely useless here!"

Lin Fan planned to absorb the surrounding thunder and lightning power.

But unfortunately, he couldn't absorb it at all.

Even when he operated the Nine Dragon Divine Cultivation Technique, it was impossible to absorb.

"It seems I still can't absorb it. Well, I'll continue forward to see what's really happening ahead!" Lin Fan gritted his teeth, deciding to move forward to see what wonders lay ahead.

Besides, at this time, Lin Fan could feel the energy of the Immortal Dragon Vein even more strongly. No matter what, Lin Fan must continue forward.

Of course, while moving forward, Lin Fan was cautious and vigilant, knowing the path was perilous, and with even a slight misstep, he might suffer.

Crack...

Crack...

Crack...

From time to time, massive thunderbolts would strike down, targeting Lin Fan, and it was fortunate that Lin Fan activated the Universal Image. Otherwise, dodging all these thunderbolts wouldn't have been easy.

Roar, roar, roar...

The sound of dragon howls echoed directly!

Lin Fan knew he wasn't far from the Dragon Soul.

After walking a little further, Lin Fan discovered a palace ahead.

It was...

A palace entirely formed of thunder energy.

Bolts of lightning circled the palace, and before even approaching it, Lin Fan could feel a powerful thunder force sweeping towards him, as if trying to incinerate him.

Lin Fan could no longer approach the palace!

Because Lin Fan knew that if he got any closer to the palace, he might really be incinerated.

Roar, roar, roar...

The Dragon Soul's roar came from within the palace.

"That human!"

At this moment, an ancient voice echoed in the void around: "I know you are cultivating the Nine Dragon Divine Cultivation Technique. If you can rescue me from this Thunder Palace, I will willingly let you refine me and help you cultivate the Nine Dragon Divine Cultivation Technique!"

So it was the Dragon Soul that spoke.

As the Dragon Soul spoke, its voice trembled, revealing it had suffered immensely within the Thunder Palace.

It was highly possible that the Dragon Soul was sealed within the Thunder Palace.

Lin Fan loudly asked: "What's the deal with this Thunder Palace?"

The Dragon Soul said: "This Thunder Palace was built by the Thunder Venerate, that undying old man, to suppress me. I've been suppressed here for tens of thousands of years. Damned it, I wish the lightning in the Thunder Palace would just strike me dead, but unfortunately, lightning can't kill me. Instead, I suffer all kinds of torments here daily; it's truly painful!"

Thunder Venerate?

Lin Fan had heard tales of him.

Twenty thousand years ago, Thunder Venerate was the most legendary figure in the Immortal Domain. Initially, Thunder Venerate was a worthless person who couldn't cultivate.

But later, for some reason, Thunder Venerate suddenly became highly attuned to the power of thunder and lightning, and his cultivation progressed by leaps and bounds. Eventually, his research on the power of thunder and lightning achieved unprecedented heights.

In the end, Thunder Venerate became the strongest in the entire Immortal Domain.

It was said that in the Late Period, Thunder Venerate fought a world-shattering battle with the notorious Demon Dragon, and the Demon Dragon was eventually subdued.

After subduing the Demon Dragon, Thunder Venerate soon ascended to the Divine Domain.

"Are you the Demon Dragon?"

Lin Fan immediately thought of a possibility, and that the Dragon Soul sealed here was likely the legendary Demon Dragon.

The Dragon Soul said: "Yes, I am the Demon Dragon!"

"Haha!"

Lin Fan laughed and said: "Since you are the Demon Dragon, why would I rescue you?"

The Demon Dragon said: "As I said earlier, if you save me, I am willing to let you refine me, aiding you in your cultivation of the Nine Dragon Divine Cultivation Technique!"

Lin Fan said: "Why should I believe you? You are the Demon Dragon, and if I truly rescue you and you turn on me, I wouldn't even have the chance to fight back."

The Demon Dragon said: "I can swear!"

Lin Fan shook his head and said: "I really can't trust your oath!"

Pausing for a moment, Lin Fan continued: "Moreover, I can't even approach the Thunder Palace now, so how can I rescue you?"

The Demon Dragon said: "As long as you agree to save me, I will find a way to allow you to enter the Thunder Palace, guaranteeing you won't get hurt!"

Lin Fan said: "Then tell me how to enter the Thunder Palace first. As for saving you, let's discuss that after I get in!"

The Demon Dragon said: "Then watch carefully!"

After the Demon Dragon finished speaking, characters appeared in the void, along with strange patterns.

Lin Fan looked into the void.

Lin Fan quickly memorized the content.

At the same time, the content in the void only lasted for a short while before disappearing.

The Demon Dragon continued: "What I imparted to you is the Thunder Control True Technique. Once you cultivate it, you'll be able to control thunder, allowing you to enter the Thunder Palace!"

"However, cultivating the Thunder Control True Technique isn't easy. With your talent, you should be able to make some progress within two or three months, allowing you to enter the Thunder Palace by then!"

"Alright, I won't disturb you any longer. Time is of the essence, so you'd better start cultivating the Thunder Control True Technique, young man. I hope you won't disappoint me!"

"Once you succeed, I will finally be relieved. To be honest, my time here is filled with endless torment, and I just want to die quickly!"
