This sound is not just a beast sound, after the sound is transmitted, the sky instantly thunders, because of the special sound, this thunder has also become particularly strong.

A thunderbolt as thick as a hundred-year-old giant tree slashed down from the sky, impartial, and was about to fall at the door of the cave. As Bei Moping expected, as soon as the thunder in the sky fell, the iron ore-rich mountain began to work, and the lightning produced a slight offset and was suction by the iron mountain.

Although the power of thunder and lightning is strong, this earth is its greatest nemesis, and the current flows through the iron ore to the earth.

Tianyi and Bei Moping glanced at each other and nodded, the initial plan had been successful, and the next step was just to wait for the next step.

Kui Niu seemed to sense that his attack had failed, and another muffled beast voice rang out again.

Moo!!!!

This time, thunder sounded in the sky again, and the thunder was much stronger than before, and in an instant, a thicker thunderbolt fell.

"It's still not giving up!" muttered North Mopin.

Ying Tianyi stared at the sky, observing whether this powerful thunder could be withstood by this iron mountain. As scheduled, the iron mountain once again absorbed the thunder, but this time it was different, after the absorption, the iron mountain began to shake, and the yellow soil between the mountains began to slide down because of the shaking.

"It's so dangerous!" Tian Yi's nervous heart calmed down a lot.

"Get ready, I feel like it's coming soon. "North Maupin is starting to get urgent.

Two lightning flashes, and suddenly the sky became a little quieter, perhaps it was because of this Kui Niu that the thunder could no longer cause damage to these red spirit stones.

After calming down for a short time, Ying Tianyi and Bei Moping both had a twelve-point spirit during the period, and then something strange appeared at this moment.

Knock, knock, knock. There was a continuous, muffled sound on the ground.

Such a tremor indicates that the forest trees in front of them cannot stop falling, and although the towering trees can block the view, they cannot hide the dangerous aura that spreads.

"It's too strong! This thunder and lightning power has already made my whole body begin to tremble slightly, and the numbness is dense all over my body!"

Rumble!!

More than a dozen trees fell right in front of him, and finally the mysterious cow revealed its form.

The huge body looks at least five zhang wide, and the height has reached at least four or five zhang high, a pair of sharp horns are very special with golden light, and there is a purple-gold halo on the two bull's eyes, a big cow's mouth This is its most special place, if this cow's mouth is opened, I'm afraid that a human will not be enough to stuff his teeth.

"Is this Kui Niu?" Ying Tianyi looked at Kui Niu's appearance in shock.

"Yes, that's it, even if it's the second time I've seen it, it's still shocking me!" Bei Moping's legs began to tremble uncontrollably, not because of his timidity, but because of his unconscious movements.

Kui Niu stared at the human in front of him and stopped, a circle of white mist gushing out of his nostrils.

"Why do you and other mortals hinder me from destroying this evil stone, and want to leave quickly to save my life, otherwise don't blame me for being merciless!" Kui Niu said to Tianyi and the others in human language.

"Kui Niu seniors, the younger generations are entrusted by the wood god Jumang, to solve the strange lightning of this Liubo Mountain, the seniors are extraordinary, and they want to come to this lightning is made by the predecessors, I don't know if the predecessors can raise their noble hands and return this land to a clean.

"How can you and other juniors know my hard work, and give you one last chance to quickly move this red spirit stone out of the cave, and then settle accounts with you after I finish dealing with it!" Kui Niu is extremely domineering in character, not at all as indisputable as Qi Qi said before.

"Kui Niu senior, if you don't make it clear, the junior will not destroy these red spirit stones for you, this thing is a priceless treasure in the human race, even Lord Mu Shen Jumang has issued a gold list!" Tian Yi said righteously.

"Ignorance! Ignorance! Since you don't want to toast and eat, then go to another world and be stubborn!" Kui Niu raised his head, and a white light flowed all over his body.

It was as if a speck of dust in the air could send out an arc of electricity, and the unusually dense power of thunder and lightning had filled everything around it.

"Brother Win, if you hold it, there will only be a way to restrain it on my side!" As soon as Bei Moping finished speaking, he immediately ran into the deeper part of the cave, in the eyes of others, this guy may have fled because he was frightened by Kui Niu's strength, but Tianyi knew that this person was fully prepared and had been waiting for this opportunity to appear.

Kui Niu kept approaching Tianyi, and every time he stepped on it, a lightning bolt would break through the sky.

Tian Yi's eyes converged, staring at Kui Niu's legs, such a huge beast should not be as fast as a small beast in terms of speed.

Just when Kui Niu's legs had just entered the safe range of Tian Yi, walls of fire rose from the ground! Through his own spiritual power and the power of Qi Qi in his body, the blue-black flames shone brightly.

The walls of fire continued to change in Tianyi's gestures, and the four walls of fire began to move slowly in the direction of Kui Niu.

Gradually, the space for Kui Niu to advance was wrapped, "Kui Niu! Since you insist on following your method, don't blame me!" Tian Yi clasped his hands together, and the wall of fire that surrounded him began to move towards Kui Niu.

Kui Niu looked very calm, and did not move in the face of the wall of fire, and when these fires burned on his body, he did not emit a painful **.

"Junior, your formation mage cultivation is not easy, I don't want your life, I don't blame you for retreating quickly!" Kui Niu snorted coldly.

Seeing that Kui Niu didn't receive any damage, Tianyi calmly calmed down, "I expected that such an attack would definitely not hurt you, but don't underestimate people too much!"

The power of fire and water is out!

The power of the fusion of water and fire that had been silent in the dantian erupted, and after merging into the formation, the original yellow flame immediately changed.

"Fire Phoenix help me!" Tian Yi shouted, this company injected two new forces into the formation, and this ordinary flame trapped formation could still speak at the same time.

The extremely high temperature caused the land to melt, but in an instant, Kui Niu's body began to burn.

"You, you junior, are so bad! you dare to hurt me, dare to hurt me!" Kui Niu couldn't stop shouting, and the injury of the flames made him angry.

Thunder for nine days, destroying everything!

The color of the coat on the back of the cow began to turn snow-white, and the sky reflected the cow becoming restless! Then five thick thunderbolts fell to the ground.
