.“ The black clouds rolling over the "Hidden Thunder Stream" were getting lower and lower, and countless powerful thunderbolts that "crackled" continued to fall down from the clouds.

In the loud sound that shook the sky, Mu Fan looked in the direction that Feng'er said, and immediately, not far in front of him, an extremely strange purple thunderbolt was constantly changing shape. After some hard work, this trace of purple lightning unexpectedly outlined a huge rough human face in the void.

Seeing this strange face that suddenly appeared in the air, Mu Fan and the others were taken aback. In the space, I saw a flash of golden light, flashing quickly and incoherently, drawing an arc in front of Mu Fan and the others. Feng'er stared at Mu Fan's side face and knew that he had cast the "Heavenly End Sword" to protect the space around him.

Just after this strange thunderbolt face was formed, a noisy and hoarse voice like an electric current rushed through the sky above the "hidden thunder stream": "You guys...... You ignorant juniors dare to trespass into my 'hidden thunder stream' without permission. Hmph, don't you know that this is my Thunder Emperor's territory?

Mu Fan stared nervously at the face in front of him, and secretly said in his heart: "Sure enough, this is the Thunder Emperor!"

The corpse devouring rat demon crouched on Mu Fan's shoulder in horror and persuaded again and again: "Lord Mu Fan, the Thunder Emperor is a monster condensed by the thunder and lightning in the heavens and the earth, and the yin and thunder are lurking here, and we can't beat him! What's more, he is still a true demon level! My lord, I think we should run away!"

"Escape?" Mu Fan replied with a slight smile: "Yin Yu and Tu Zhen haven't come out yet, if I run away like this, will I still have the face to meet them in the future?" turned his head to Feng'er and smiled: "Miss Feng'er, be careful yourself, I'll be there for a while." As he spoke, he flew up.

Feng'er hurriedly said, "Wait...... Wait a minute......"

"What's wrong?" Mu Fan asked when he stopped his forward figure when he heard this. Not...... It's nothing. Feng'er's face turned red and whispered, "You...... Be careful yourself. ”

"Don't worry, I'll be fine. Mu Fan nodded and replied, turning to the Wu on his shoulder and said, "Hey, you can fly yourself, right?"

"Of course it will!" Wu flew off Mu Fan's shoulder and stayed with Feng'er. Knowing that this guy was going to provoke Lei Huangwu, he didn't want to follow him to take risks.

Mu Fan smiled, turned around and flew towards the huge thunderbolt face.

"Hahaha-" The hoarse and trembling laughter spread, and the Thunder Emperor was obviously very angry: "Good boy, I know that this is the place of the Thunder Emperor, and I dare to come, I won't kill you, and the other monsters still think I'm afraid of you!"

The thunder and lightning in the space began to become violent, and the current flowing on the strange face began to beat continuously, gradually extending downward, and within a few breaths, even the hands and feet and torsos were outlined.

After the entire body fully appeared, the Thunder Emperor moved his body, causing the surrounding electricity to surge constantly. I saw his empty purple lightning eyes staring at Mu Fan and snorting repeatedly: "Boy, you are breaking into my 'Hidden Thunder Stream' at this time, are you deceiving me, the Thunder Emperor is injured?" Tell you, to deal with a little demon with weak demon power like you, my Thunder Emperor only needs to move his fingers, it is enough to crush your bones and scatter ashes!"

As soon as Lei Huang's words fell, thunder and lightning flashed in the surrounding space, and before Mu Fan could change his mind, he realized that he was already trapped in a cage made of electricity.

"Be careful......" Feng'er Lian, who saw Mu Fan trapped behind, shouted loudly.

"Rest assured. Mu Fan responded by reaching out his left hand to pull the thunderbolt cage.

Since the last time he escaped death in the East China Sea in the human realm, Mu Fan has had an unusual and intimate feeling for the thunder and lightning in the heaven and earth. At that time, when he was still lying in the tomb of the mountain behind the Sage Peak, in the darkness that he didn't see, Mu Fan felt that his right hand seemed to contain a powerful thunder and lightning power. This power of thunder and lightning is exactly what Mu Fan relied on when he dared to call a battle with the Thunder Emperor at this moment. Of course...... and the magical origin of the "Sun, Moon and Star Flag" on his body.

"Give me—disperse!" With a loud shout, a surging purple electric dragon sprang up from Mu Fan's right arm, and the electric dragon's big mouth opened and bit down on the net fence crisscrossed by the thunder and lightning cages.

"Oh, the power of thunder and lightning cultivated for 20,000 years?" the Thunder Emperor seemed to be slightly surprised and said, "It seems that I underestimated you!"

"This ...... This thunder and lightning is ......," Mu Fan was at this time with all his strength to encourage the hideous purple electric dragon on his right arm to shake the surrounding thunder grid, and suddenly felt a more majestic and mighty current surging towards him, and his right arm was suddenly scorched with a burst of green smoke.

"Wow......" was hit by this powerful current, and Mu Fan violently spat out a mouthful of blood. Ignoring the injuries on his body, Mu Fan immediately made a gesture with his left hand, and the space around him was gloomy for a while, and the "Sun, Moon and Star Flag" had already stretched out a starry sky in silence, covering Mu Fan's whole body firmly.

"Huh?" the Thunder Emperor was taken aback, and as soon as the right arm formed by the electric current flipped over, a thunderbolt broadsword shining with purple light suddenly appeared in his hand.

"This is how the kid offended my Lord Thunder Emperor ended up like this!" A flash of lightning flashed, and the thunder and lightning broadsword slashed towards the top of Mu Fan's head in a degree that was indistinguishable to the naked eye.

At this moment, a turquoise curved tooth came first, catching up from the deep and dark mountain stream, and collided with the Thunder Emperor's purple electric knife.

There was a crisp "crackling" sound, and the demon soldier's "fangs" had already produced subtle cracks.

"Where did the stinky boy come from?" the illusory figure of the Thunder Emperor turned around, and suddenly saw two small figures flying up from the bottom of the stream.

"It's obscurity and smearing. Mu Fan's heart was relieved, and he shook off the huge electric current wrapped around his right arm and said, "These two guys finally came out safely." ”

The two demons that flew up were the snake demon Yin and the rhino demon Tu Zhen. After entering the "Hidden Thunder Stream", the two wandered at the bottom of the labyrinth-like stream for a long time, but they found nothing, and finally flew out, just in time to see the moment when Mu Fan was in distress.

The two demons flew up towards the true demon Thunder Emperor. The snake demon suddenly stopped his body sharply in mid-air, spread his hands wide, and then clasped his fists in front of his chest and shouted, "'Petrified Pupil'!"

At the moment when Yin Yu shouted the words "Petrified Pupil", Mu Fan, who was not far from the Thunder Emperor, suddenly felt that his body was a little sluggish. Mu Fan was so frightened that he struggled to break free from the thunder and lightning cage around him and flew away from the place.

After flying out of the distance, Mu Fan turned around and looked at the Thunder Emperor, and suddenly his eyes widened in horror.

I saw that in the dark mid-air, a huge black snake phantom appeared behind the snake demon, and the two scarlet eyes of the black snake phantom were staring indifferently at the Thunder Emperor in the distance. And the body of the Thunder Emperor, whose body was all made of crimson electricity, was gradually solidifying and petrifying, and it had changed into a huge gray stone statue.
