"Blackie!" Mu Yun saw that Xiao Hei did not listen to dissuasion and took risks alone, his heart was extremely nervous, a pair of beautiful eyes opened the boss, and his figure swept to the city gate of Dragon and Tiger Pass in a flash.

Outside the gate, the black fog in the sky flew around with the dim yellow sand, and a gust of wind hit the face, drumming the white clothes on Mu Yun's body fluttering in the wind, the long hair was messy behind his head, and a pair of charming eyes revealed seven points of calmness and three points of worry, staring at the black fog area full of infinite power in front of him.

"Aang!" The sound of the dragon's groan faintly came from the black mist, as if to show the dragon's anger to the world, Mu Yun heard the sound, and her heart couldn't help but shake up, and the intense worry quickly expanded in her body, filling the meridians and skin of her body.

"Blackie!" Mu Yun called softly in his mouth, and then the silver mangs on his body flashed, and gradually the silver mangs flourished, enveloping half of the city gate under the screen, "Hum! The power of space was exerted to the limit, and a low humming sound was heard, but Mu Yun's teleportation was never successful.

"What's going on?" Mu Yun looked at the black fog covering the sky in front of him suspiciously, and said to himself, "Why can't the power of space be used at this time?" Could it be that this black fog is blocking my ability to teleport in space? She exhaled slowly, put away the silver light outside her body, and began to fly forward in the sky.

"Whew!" A white light flashed, and Mu Yun escaped into the black mist outside the Dragon and Tiger Pass.

"Blackie! Where are you? Mu Yun looked left and right while flying, carefully looking for Xiao Hei's traces, and his spiritual power wanted to let go of the accelerated search speed, but found that at this time, even his spiritual power could only be released to a distance of twenty meters.

"Could it be that this centaur beast is exercising some kind of restraint?" Mu Yun guessed in his heart, "The ability to seal off all the special effects? ”

"Sister!" Xiao Hei's echo sounded in Mu Yun's mind, "I'm two kilometers in front of you, on the back of the centaur beast, don't come here, I'm going to succeed." ”

"Why did you succeed?" Mu Yun asked, "Don't you know that once it discovers your sink, you won't even have a chance to escape?" ”

"Hehe, sister, you don't have to worry," Xiao Hei laughed fearlessly, "The four legs of this centaur beast are not horseshoe but human feet, so I won't be in danger." ”

"Is there a connection between the two?" Mu Yun was confused by Xiao Hei's words, "You are obedient and obedient, come back immediately, do you hear?" ”

"Oh, sister," Xiao Hei was a little anxious, "don't rush me, let me stop now, then all my efforts just now will be in vain, and I will also be in danger, can you give me a few more minutes?" I promise to return to you unscathed! ”

When Mu Yun heard Xiao Hei say this, he didn't dare to urge again, so he said helplessly: "Okay, okay, be careful yourself, notify me immediately if there is anything!" ”

"Ah!" Xiao Hei answered, and then stopped talking.

"Whew!" The roar of the centaur beast suddenly resounded throughout the heaven and earth, shaking the ground violently, Mu Yunfei was in the black mist, slowly approaching the centaur beast, and there was a sound of gold and iron resonating and shouting on the ground below at this time, thinking that her undead army was fighting with the army of the underworld.

Mu Yun's palms quickly alternated in front of him, and the energy of the seven natural forces gradually converged on his arms, with the dark energy being the most significant, and the black light enveloped the light of the other six series of energy.

"Go!" Mu Yun let out a clear sigh in his mouth, and pushed the two black pillars of light on his arms forward, "Woo! Two gusts of wind then roared, and black pillars of light shot out, hitting the battlefield in front of them.

"Boom!" After two violent explosions, I could only hear the sound of the crisp bones colliding on the ground, and then I saw the army of the undead on the ground who had been trampled to pieces stand up again.
