Donghuang Taiyi touched the cold door and nodded to everyone, and the seven elders of the Yin and Yang family behind him placed the box in their hands in the groove on the gate in the order of the Big Dipper.

Mu Chen slowly stepped forward and put the Reverse Scale Sword into the gate, the sword spirit of the Reverse Scale Sword seemed to have found a home, and Mu Chen could actually feel that the evil qi on its sword body was slowly weakening.

In the hands of the moon god, holding the red box, that is, the phantom sound treasure box in "Qin Shi Mingyue", she recited the incantation slightly in her mouth, the box of the seven heirs slowly opened, the pagodas in the seven boxes were stacked one by one, and seven beautiful music intertwined into a song, surrounding the gate.

"Click, click...", the door seemed to have a spirit, and as the music played, the gears of the mechanism slowly turned, and the door gradually opened.

Behind the door was an isolated world, and little by little blue light overflowed from the door, and the group slowly walked in.

In this area, everything is extremely chaotic, as if the sky and the earth are not open when the turbidity is vast, and in the endless dark night of the sky, the seven stars in the shape of the Big Dipper are the brightest and dazzling.

Donghuang Taiyi glanced around, and said expressionlessly: "My lord, please go under those seven stars, and we will protect the Dharma for you." ”

"Hmm." Mu Chen nodded and walked under the huge Big Dipper pattern, which seemed to be the center.

A group of people from the Yin and Yang family glanced at each other, and walked to Mu Chen's side one after another, surrounding Mu Chen in the center, and the eight swords of the Yue King exuded a cold light, guarding the world at the door under the grip of the sword holder.

The mouths of the Eastern Emperor Taiyi and other Yin and Yang families murmured, and the seven shining lights of red, orange, yellow, green, cyan, blue, and purple rose to the sky, and in this empty world, the sound of seven boxes intertwined, ethereal echoed around.

The seven shining stars were each hit by seven colored lights, and then began to flicker and flicker, and even a few began to tremble.

Mu Chen felt the turmoil in this place, and glanced at the people of the Yin and Yang family again, if it weren't for the incantation in his mouth, Mu Chen would really think that they were lifelike wax figures in the wax museum.

Time was constantly passing, and the Big Dipper on the top of Mu Chen's head began to gradually turn into seven colors: red, orange, yellow, green, cyan, blue, and purple.

After two or three breaths, the light of the seven stars began to weaken, and then the light began to slowly fade towards annihilation.

Losing the shining light of the Big Dipper, this airspace completely dimmed, and at this moment, only the lantern in the hands of the seven elders exuded a faint light, in this vast dark night, like the light of fireflies.

An invisible weight slowly suppressed from his head, Mu Chen could barely open his eyes under the pressure of this light, and his vision gradually became blurry, and the figures of Donghuang Taiyi and others in front of him began to gradually blur.

The black sky was "Click!" After the sound fell, a brilliant cyan light poured down, falling on Mu Chen's body, the weight slowly dissipated with the fall of the light, and Mu Chen's vision became clear.

The inside and outside of that cyan pillar of light seemed to be like two worlds, and at the same time, an incomparable force began to penetrate into Mu Chen's skin and pierce into the bone marrow.

This long process was extremely painful, Mu Chen was almost tortured by this stinging sensation and passed out, beads of sweat dripping down from his forehead, wetting the white robe on his body.

When the cyan light completely dissipated, Mu Chen glanced around, only to find that the Eastern Emperor Taiyi and the Great Priest, the Moon God, and the Yin and Yang Patriarchs were gone.

The darkness in this mysterious airspace had completely disappeared, and when he could see the rock wall clearly, Mu Chen realized that this was actually a hidden cave.

"Is this power?" Mu Chen felt that the energy in his body was constantly surging, even a few points stronger than Rena's 10% energy, and with a wave of his hand, the anti-scale sword flew into his hand.

At this time, the sword body of the Reverse Scale Sword was surrounded by seven colors, red, orange, yellow, green, cyan, blue, purple, seven gorgeous colors made up for the incomplete Reverse Scale Sword Body, a broken ancient sword, and it became perfect at this moment!

"What a domineering sword intent!" In the main god space, Jing Ke felt the powerful sword qi and couldn't help but exclaim.

The sword intent emitted by the sword qi made Jing Ke tremble, such a powerful sword intent was impossible to display even at his peak, and Mu Chen was stronger than the hundred-step flying sword he used with all his strength just by taking a sword in his hand!

I'm afraid that in this world, even the Sword Saint Gai Nie, and the top masters such as Wei Zhuang joined forces, they may not be able to block Mu Chen's casual blow.

Mu Chen only performed one move, although it was just an ordinary move, but the powerful sword qi collided with the entire cave, which actually made the entire huge cave tremble slightly.

With just one move, it actually has the power of the sky and the earth cracking!

"Is this the power of Canglong Qisu, it's really powerful...."Jing Ke looked at the rock wall that was gradually covered with cracks, and couldn't help but exclaim.

Before you know it, his submission value has increased by 40%, and it is likely that this is out of respect for the strong, and surrender.

"Boom!"

Mu Chen slashed out with a sword, and the huge iron gate was bent by the bombardment of the sword qi, and the powerful sword qi cut through the space and blew out a violent hurricane.

For a while, the entire cave was filled with smoke and dust, and the air became a little turbid.

"Ding Dong, congratulations to the host for obtaining the power of the Canglong Seven Nights, and the plane mission has been completed!" The voice of the system sounded in my head, and it was still so mechanical.

"Is it possible to turn on the plane lottery system?" Mu Chen asked in surprise, after completing this plane task, it means that he already has the qualifications to shuttle to the next world.

The next world is still random, as for what world it will shuttle to, it all depends on your character, I hope you don't cross into the desolate plane, otherwise it will be the first death before you get out of the school!

PS: The Tianxing Nine Songs plane is basically over, and I'll go back to the Super Divine Academy tomorrow, and I'll catch a girl, guess which one?
