Yan Lan stopped falling, her mind tensed, and she was extremely cautious.

In the surrounding mud and rocks, the gray gas was more dense, as if the deeper you went underground, the closer you got to the source of the gray gas.

Fortunately, this gray qi is not dangerous to Yan Lan, and even the soul devouring vortex under the primordial god can also devour the gray qi wantonly.

At a depth of 100,000 miles underground, the Soul Locking Forbidden Array is beyond the reach of the whip.

Here, Yan Lan didn't feel the slightest bit of soul oppression.

No matter how strong the Xuan clan is, it is difficult to touch such a deep underground.

Yan Lan lowered his head and stared downward, the power of the thunder soul spread cautiously, hoping to touch the breath of the thunder sword.

"My soul power has probed for three thousand miles, but I still haven't found any trace of the thunder sword. However, the further down he goes, the stronger Lei Neng becomes. It seems like...... It seems that there is a source of thunder energy in the ground, and the monstrous thunder energy even surpasses the original five-colored thunder. ”

"What kind of thing exists deep in the earth that can make Thunder Sword so crazy?"

Yan Lan was puzzled, took a deep breath, and galloped down the ground.

Ten thousand miles down, in the dark underground, thunder began to wander visible to the naked eye.

Yan Lan stretched out his finger and lightly touched one of the thunderbolts.

"Snort......"

The thunderbolt, which was only as long as a grain of rice and less than a hair's thin, exploded at his fingertips, and immediately released a sharp thunder blade, cutting his tempered and incomparably strong skin in an instant, a deep wound that could be seen to the bone.

The blood was gurgling, Yan Lan's eyes widened in surprise and she gasped.

"How is that possible? What kind of thunder energy is this, so domineering. I only touched a ray of thunder the size of an ant, and it hurt me so much. If only I could put these thunderbolts. gathered together, forming a thousand-foot-long sword ray. The power of this sword is enough to split mountains and seas, and even the powerhouses of the third realm will be shocked. ”

Yan Lan swallowed her saliva and looked into the ground.

I saw that the entire vertical passage was no longer pitch black, but shrouded in a deep purple light.

What formed these purple rays was the small thunder rays that floated and wandered.

The further down it goes, the more intense the purple mangs become.

Yan Lan could feel it. At the bottom of this passage, there was a purple light cluster, shining with an incomparable purple brilliance, like a purple sun, dazzling and unsightly.

"Is this a fortuitous creation, or is it a line between life and death?"

Yan Lan muttered to himself, he didn't believe in every adventure. It's going to be a kind of chance.

Sometimes, it can also be a killing machine.

"Thankfully, these thunderbolts are like plankton. Not to be manipulated by others. I can use a little spiritual power to open it. Otherwise, I will rush to the ground recklessly. I'm afraid that I will be bombarded by these thunderbolts. ”

Yan Lan stretched out her right hand. Pinch your hand to form a transparent defense in front of you. Then sacrifice the Luo Tian umbrella, and then quickly go deep into the ground.

He couldn't wait to know what was going on underground, and where did Thunder Sword go?

The purple rays in front of him are getting brighter and brighter, and the floating thunderbolts are becoming denser and denser.

None of this surprised Yan Lan.

What shocked Yan Lan the most was that in his body, the Heavenly Thunder Soul Yuan began to tremble, and the power of the Thunder Soul gradually became chaotic, as if the thunder power in his whole body was gradually being manipulated by others.

"This is not controlled by a strong man, but as I thought, this underground has an existence that is close to the origin of thunder energy. It is more powerful than the thunder of the five-colored heavenly thunder. ”

"Today, even if I, Yan Lan, give up this Lei Xiu, I must know what is hidden underground. I have Zen heart to protect my body, plus before, Zen heart saved my life under the five-colored thunder, this is my confidence. ”

Yan Lan's eyes were crazy, and his body was falling wildly.

This time, Yan Lan no longer stopped halfway, and went down in one go, no matter what kind of changes he suffered, he did not stop for a single step.

In front of me, the purple rays are bright, like thousands of suns shining at the same time.

Even with Yan Lan's eyesight, he couldn't see anything, and there was nothing else in front of him except a piece of purple.

I don't know how far he has gone down, whether it is 30,000 miles, or 50,000 miles, Yan Lan has no strength to calculate, he desperately rushes down, and he can't stop wanting to know the truth.

Just when the thunder energy in Yan Lan's body was already so agitated that it was almost boiling, a warning suddenly appeared in his heart.

"It's not good, under this killing machine, it is impossible for none of the ten thousand me to survive. ”

Yan Lan gritted his teeth and was about to step into the Zen space.

At this moment, a whistling and humming sound came, and a sword shadow blocked in front of Yan Lan.

Yan Lan's eyes couldn't see it, but his soul power vaguely noticed that the sword shadow was the thunder sword.

"Hmm, the Thunder Sword actually knows to save me, it has no instrumental spirit, only a trace of imperceptible, not to be called spiritual wisdom, to be exact, it is a kind of long-term understanding fluctuation with people, everything has a spirit, it is really wonderful. ”

When Yan Lan sighed in his heart, the thunder sword sword spun, but the thunder mang that came towards Yan Lan did not touch the body of the thunder sword, and immediately rolled upside down.

"It's strange, that Lei Mang, he didn't hurt the Thunder Sword, could it be ......"

Yan Lan was thinking, but he felt that there was an extra thing in his hand, and when he grabbed it with his hand, it was actually a thunder sword.

Lei Jian took the initiative to run into Yan Lan's palm.

Yan Lan was both surprised and surprised, and before he could think about the reason, suddenly the thunder sword generated a huge traction force, taking him towards the ground quickly.

"Does Thunder Sword want to take me to see the origin of Thunder Energy?"

Yan Lan was surprised in his heart, but since the Thunder Sword saved him, he naturally wouldn't harm him, so he condensed his mind and let the Thunder Sword drag him down.

I don't know how far I went down, Yan Lan felt the traction of the thunder sword disappear, and then the thunder sword took off his hand.

After a while, the thunder in front of Yan Lan's eyes slowly dimmed, and his eyesight gradually saw the surrounding scene clearly.

At this time, Yan Lan was suspended in the air, turning his head to look around, this was a cave with a radius of thousands of miles, and the cave was filled with endless purple manglei energy.

As far as the eye could see, it was simply an ocean of thunder energy condensed, filled with a violent aura of destruction, making people dizzy, suffocated, and succumbing.

Yan Lan had no doubt that if he was thrown into the sea of thunder energy, he would be wiped out and his soul would be scattered in a matter of time.

"This ...... Is this the source of thunder energy? Across such a deep earth, even my keen thunder soul power can't detect the slightest, why can the thunder sword sense it when I first stepped into the Desolate Ghost Slope area. Thunder Sword, how did you sense it?"

Yan Lan muttered to himself, everything in front of him was even more shocking than when the five-colored heavenly thunder fell from the sky.

"Is it you, did you bring it?"

A crisp and proud voice sounded impressively, and it was particularly abrupt and strange in the depths of the ground that were more than 100,000 miles underground.

Yan Lan's heart trembled suddenly, his expression changed drastically, and he was shocked in his heart: "Here, someone is actually talking?" Yes...... Who is it?" (To be continued......)
