Rumble! There was a loud bang in the sky, like the sound of ten thousand drums, and thunder and lightning intertwined in the night sky, illuminating the entire battlefield. Mu Yu stood in place, facing the impending thunderstorm, his eyes flashing with determination.

The battlefield between the two is located in a majestic mountain range, surrounded by ancient trees and rocky mountains.

The monk stood proudly on the mountain peak, holding a long sword of ugin and wearing a black brocade robe. His gaze was cold, as if he looked at Mu Yu like an ant.

Mu Yu felt the killing intent of the other party, he did not flinch, his hands were folded, and the thunder in his body was surging. Behind him, thunder flickered, and a huge thunder dragon phantom slowly emerged, exuding an astonishing coercion.

"Nine days of thunder!"

Mu Yu shouted, and the thunder dragon phantom behind him raised his head to the sky and roared, turning into a bolt of lightning and rushing straight at the enemy. At the same time, Mu Yu's figure flickered, turned into a cloud of green smoke, and instantly appeared behind the enemy, slapping out with one palm.

The enemy seemed to have expected it, and with a wave of Ugin's long sword, a black sword qi surged towards Mu Yu like a huge wave. Mu Yu's figure was shocked back a few steps, and a trace of blood overflowed from the corner of his mouth.

"I didn't expect your kid to be so strong, and it's worth the deity's full effort." The voice of the enemy is like that of nine ghosts, which makes people shudder.

Mu Yu wiped the blood from the corners of his mouth and sneered: "It is the greatest honor for me and other cultivators to be able to fight with a master like you. ”

As soon as the words fell, Mu Yu's body was full of thunder, and his body seemed to have become a source of thunder, and a violent force was constantly accumulating in it. The enemy seemed to feel Mu Yu's determination, and there was a hint of jealousy in his eyes.

"Thor's Fury!"

Mu Yu roared, and the thunder power of his whole body converged towards the pitch-black thundercloud in the sky without reservation. In an instant, the thunderclouds rolled wildly, and a force that destroyed the world gradually took shape.

The enemy didn't dare to be careless, he clenched the Ugin long sword, and the spiritual power in his body poured out with all his might, and a majestic mountain peak phantom appeared behind him, as if he wanted to crush the heavens and the earth.

"The power of mountains and rivers!"

With a low shout from the enemy, the phantom of the mountain peak instantly turned into a huge palm print, and it was suppressed towards Mu Yu's location.

At this moment, Mu Yu's thunder power was also ready. He held his hands in the void, as if holding up a huge pillar of thunder. The power of that pillar of thunder was infinitely powerful, as if it was about to tear the entire battlefield apart.

"Thunder Strike!"

Mu Yu shouted, and the power of the thunderbolt rose into the sky, hitting the dark thunderclouds. The two met in the air and burst into brilliant light, as if to illuminate the entire starry sky.

Rumble! Another earth-shattering sound rang out, and the entire battlefield trembled. The furious energy spread in all directions, the mountains and rocks collapsed, and the ancient trees burned to the ground, as if the end had come.

The smoke and dust dissipated, and I saw Mu Yu standing in place, and the thunder light on his body gradually converged. Although his face was a little pale, his gaze was more determined.

The enemy was repulsed for dozens of feet, and a trace of red blood spilled from the corner of his mouth. He looked up at Mu Yu, a hint of surprise flashing in his eyes.

"You've been able to fight me this far......" the enemy said with some surprise.

Mu Yu smiled lightly: "Being able to compete with a master like you is the greatest honor for cultivators like us. ”

The enemy glanced at Mu Yu deeply, and then looked up to the sky and sighed: "In this battle, you deserve my respect." It's a pity ......"

Before he could finish speaking, the enemy suddenly attacked. A black sword aura swept towards Mu Yu like a tornado. Mu Yu's face froze, and he quickly met the opponent's attack.

The sky gradually became overcast, and dark clouds rolled and surged in the sky like a group of black dragons. Thunder loomed in it, and the low roar was like the sound of ten thousand drums, heralding an unprecedented battle.

Mu Yu slowly raised his hands, palms up, as if inviting the thunder of the sky to come. A powerful aura was released from his body, which was the thunder power in his body, majestic and vast, as if it was endless.

The thunder erupted instantly, and a huge thunderbolt struck down from the sky, as if it was about to tear the heavens and the earth apart. However, Mu Yu was still standing on the altar, and his figure seemed more and more tenacious under the light of thunder.

When the thunder touched the Dharma platform, Mu Yu's thunder power rose from the Dharma platform, forming a golden wall of light visible to the naked eye. Thunder and lightning slammed into the wall of light, making a deafening loud sound that instantly distorted the space around it.

The force made the air around him tremble, and even the ground was shaken out of cracks. However, Muyu is like a majestic mountain, regardless of the wind and rain, it will always stand.

He raised his hands to the sky again, and more thunder fell from the sky, turning into huge thunder and lightning. Every bolt of lightning is enough to destroy a city, but Mu Yu collects them one by one as if he was playing.

His thunder surged wildly, directing the lightning to the enemies he had already targeted. As soon as those enemies came into contact with those thunderbolts, they were blown to the ground in an instant.

The dark clouds in the sky seemed to sense something and began to surge in a panic, as if they were running away from something. And Mu Yu's figure looked even more majestic in this violent thunder and lightning.

Her hands quickly drew mysterious symbols, and the elements in the air began to vibrate, condensing into a cloud of thunder and lightning. The clouds in the sky gathered rapidly, lightning and thunder, and the wind roared, as if announcing the coming of a great war.

Mu Yu watched all this calmly, and his heart was calm, like a pool of autumn water. He knew that his enemies were behind the thunder and lightning, waiting for him to fall into the trap of fear. He slowly raised his hand, and a pure energy surged through him, which was his strength against thunder and lightning.

Thunder and lightning collided with his energy in the air, triggering a great battle that shook the heavens and the earth. The fury of thunder and lightning slammed into his body as if it were about to tear him apart, but he was tenacious and could not stand. His energy formed a strong barrier to block all lightning attacks.

Then, he began to fight back. His hands once again drew a mysterious symbol, and a powerful energy erupted from his body, soaring into the sky. The lightning collided with the energy, causing an explosion that was even more violent than before.

The fist and the thunder collided in the air, bursting out with a strong light, like a sudden appearance of daylight, shocking people's hearts. Mu Yu's figure was as steady as a rock in the wind, and the thunder was instantly dispersed by his fist.

The air around them was torn apart by the aftermath of the explosion, and the wind was blowing wildly, flying sand and rocks. Mu Yu's figure didn't move, but his gaze had already looked in another direction.

Mu Yu's eyes flashed, and he raised his hand and punched out. The two forces collided again, and the explosions rang out again and again, shaking the surrounding rocks and rocks.
