Everyone thinks I'm a wealthy doctor's son-in-law

Looking at each other with a smile, Pan'er patted his chest and said, "I'm relieved with your words, you go! If it's dangerous, don't be brave, let's find another way, I'll protect you here! As long as With me here, no one can go in and disturb you!"

Lu Ming smiled wryly when he heard the words, where did people from the barren mountains bother him?

But yes, Pan Pan, a person who doesn't know how to cultivate, can't enter the cave to withstand the power of lightning.

Lu Ming stretched out one hand, beckoning Pan'er to hand over the black iron box to him, and the latter handed it over without hesitation.

As a result, there was a black iron box, and Lu Ming turned around and walked towards the cave.

"Be careful, don't be brave, I don't want to lose you, the only friend here..."

Pan'er's voice came from behind, and Lu Ming waved his hands without looking back, signaling her not to worry.

Stepping into the cave, one wave of violent and restless energy rushed towards the face, like endless waves, one wave was higher than the other, and the dazzling glare became brighter and brighter.

Lu Ming squinted his eyes, condensed the domineering aura of the body, resisted the violent thunder and lightning in the cave, and walked forward cautiously. He saw the so-called thunder pool behind the corner of the cave.

This place looks ordinary, just a slightly larger cave, but what is weird is that there is a three-meter-square pool on the ground of the cave, which is not water, but a tumbling arc of thunder, as if from the sky. It's like moving a thundercloud down and leaving it here.

In the thunder pool emitting dazzling white light, arcs of lightning interweave, like countless little snakes entwining and climbing.

The terrifying aura that emanated made Lu Ming feel like his hairs were bursting. Even with his domineering body protection, he felt that the hairs all over his body were standing up and jumping with the electric current in it.

"The terrifying power of thunder and lightning is even more violent than my domineering power."

This is the most powerful energy that Lu Ming has ever seen. What is churning in this thunder pond is the thunder of heaven, the power of heaven and earth. Naturally, it is not comparable to the domineering energy he condensed through cultivation.

Taking a deep breath, Lu Ming took out the black iron box.

Snapped!
At this moment, a burst of air came, and a lightning arc flickered in the thunder pool, as if penetrating space, and hit the black iron box in the next second, scaring Lu Ming back a step, Looking at the black iron box in his hand again, he was surprised to find that there was a strange change on it.

The original black iron box actually showed a slight white light, and the lightning arc climbed on it as if it was not scattered.

"It does work." Lu Ming was overjoyed. It seemed that Pan'er was right. The thunder in the thunder pool could open the box.

But what to do now?Those thunders are not something he can arouse, they are heavenly thunders, which are equivalent to the power of heaven that a strong man endured during the tribulation period, heavenly thunders!

After pondering for a while, Lu Ming casually threw the iron box into the Thunder Pond.

Rumble!
When the black iron box fell into the thunder pool, there was a thunderous explosion, which made people's eardrums hurt, and then they saw countless lightning arcs hitting the black iron box, and each thunder arc went straight into the black. Inside the iron box.

All of a sudden, thunder and lightning lingered, and the cave was extremely terrifying. The thunder in the thunder pool was churning, but fortunately, the black iron box was like a bottomless black hole, and began to quickly absorb the power of thunder and lightning in the thunder pool.

Lu Ming smiled at the corner of his mouth, looked at the scene in front of him, and murmured: "The effect is remarkable. There are countless cracks on the black iron box. You should be able to open it and get the key in it! After the key is in hand, this trip to Fengming Mountain The chances of obtaining the Demon Heart are much greater."

The Heaven Punishing Sword, Demon Heart and Buddha Bone are the things he must collect. Only by getting all three together can he save his life, otherwise his body cannot bear the Five Elements Ring, Dzi Bead and the Earth Heart he will get in the future. The combination of the three talents is the sacred object of the fairy world, the fairy clan and the demon clan. It is conceivable that such a powerful fusion of the three, how can a flesh and blood body bear it.

In the thunder pool, the thunder arc quickly climbed towards the black iron box, and then dissolved in it. The black iron box was shining with brilliance, and countless cracks like spider webs appeared on the surface.

……

In the depths of Fengming Mountain, on the other side, stood a group of people in front of an illusory light curtain.

Suddenly, the light curtain trembled violently, and then quickly became more illusory.

"How could this be? The seal has suddenly weakened a lot." A man's complexion changed drastically and he exclaimed.

In front of everyone, a holy and beautiful woman stood with her hands behind her back, her brows were slightly frowned, her long hair fluttered in the wind, and her white hair did not match her age.

"Princess, the seal is loose, it seems that someone is destroying Lei Chi!"

This woman is none other than the lovesick and white-headed fairy princess, Tianjiao!
Tianjiao was expressionless, and said in a deep voice: "Tianhe, the two forbidden places outside Fengming Mountain that are firmly sealed, Thunder Pond and Fire Field! My fairy clan destroyed the fire field, loosening the seal of Fengming Mountain, and gathering practitioners The alliance has come to this point, and then it will be wiped out! You have promised that no one in this world can shake the thunder pool, now, why?"

Standing behind Tianjiao was Tianhe. If it had been a few days ago, even though Tianjiao was a fairy princess, if she dared to talk to him like this, she would have jumped up.

But today is different, today's Tianjiao seems to be a different person, not only her temperament has changed drastically, but her cultivation has also improved by leaps and bounds, reaching an unimaginable level.

Tianhe bowed and said: "Thunder and fire from the sky are originally two forbidden places outside Fengming Mountain that are firmly sealed. The fire from the ground is easy to destroy, but the thunder from the sky is difficult to ascend to the sky. I don't know why someone can destroy the thunder pond."

"Then why are you still standing there!" Tianjiao's face darkened, and she shouted: "The seal is getting looser and looser, and the remnants of the demon race will definitely try to break out, you stay here, if any remnants of the demon race rush out, they will be killed without mercy! "

"Tianhe, follow me to the Thunder Pool! Who dares to destroy the Thunder Pool, can have such strength!"

After Tianjiao finished speaking, she didn't see that she had already appeared a few feet away, Tianhe hurriedly followed, and headed towards the place where Lei Pond was located in Fengming Mountain Range.

Before going far, several people suddenly rushed out of the illusory light curtain, trying to escape from this place, but they were beheaded by the immortals just after they appeared.

As for this scene, Tianjiao didn't turn her head back, but ran in Lei Chi's direction.

At this moment, Lei Chi.

The thunderclaps that were originally filled with thunder pools had all been poured into the black iron box, and countless cracks appeared on the box. Lu Ming waved his hand, and the black iron box fell into his hand, and the domineering palm churned around it.

"With just a little external force, the black iron box can be opened!"

Lu Ming muttered, and immediately his body shook, and he shook his palm violently.

boom!
A strong domineering force gushed out and squeezed on the black iron box, and the box broke into pieces of crystals, revealing a small, special key.

But when Lu Ming was excited, a sudden change occurred.

boom……

In an instant, an extremely terrifying lightning arc emanated from the fragments of the broken black iron box, and then thunder dragons wrapped around Lu Ming's body.

creak...

The thunder dragon condensed by the thunder arc is like a real substance, with extremely terrifying violent power. The domineering body armor on Lu Ming's body makes a creaking sound under the entanglement of the thunder dragon, and it seems to burst at any time.

"Miscalculated, I actually ignored the fact that the black iron box swallowed the power of lightning!"

Lu Ming regretted it too much. He only wanted to get the key in the black iron box for a while, but he ignored the thunder and lightning power that the iron box swallowed the entire thunder pool. Once broken, the thunder and lightning power in it would be released.
