"The underground legion of the demon clan, this ......"

Feeling the tremor of the city, combined with Ye Bufan's words, the others immediately panicked. If the entire underground depths of Aoba Castle are hollowed out by the other party, how will this battle be fought?

"Hehe, you don't have to worry, although the underground legion of the demon clan is wild, it is hitting stones with eggs, if you don't believe it, look at this!"

Ye Bufan glanced at Bai Buqi, who immediately understood, waved his big hand, and a white light flashed in the air, and he saw a transparent crystal with a length of three zhang, a width of two zhang, and a thickness of about one foot appeared in the air.

"What is this?"

Everyone couldn't help but be stunned for a moment, and the matter of the demon clan's underground army attacking the city was temporarily put aside. This transparent cuboid is obviously made of crystal, but what exactly does it do?

Most people are in a state of bewilderment, even if they rack their brains, they can't think of a reason why they came.

"This is a double shadow projection formation arranged by using the characteristics of memory crystals, and there are not many materials used, but it is particularly troublesome to arrange, so it is understandable that you can't understand it. Ye Bufan muttered softly.

Then he took out a white array flag, gently waved out the mysterious trajectory with one hand, and pinched out the complex seal with the other hand, after the formation flag trajectory and the seal were combined, the air rippled, and the void was slightly twisted, as if something was about to be born.

"Look, everybody!"

Bai Buqi's eyes, who had been waiting for a long time, flashed, and two pale rays of light suddenly shot out between his palms, and two voices shot on the cuboid crystal, and then there was a vibration, and a somewhat dim image began to appear on the crystal cuboid.

"It's ......"

All the monks in the city changed color for it, what kind of means is this? It was the siege of the underground demon army, and it was perfectly presented. Although the environment on the video is a little dim, everyone can see it clearly.

"Huh. ”

Ye Bufan smiled faintly, feeling a little proud in his heart, after all, this was arranged by himself, although with the help of external forces. But even if he was only a conductor and didn't personally participate, those who arranged it by hand still couldn't figure out the principle.

Just like Ye Bufan looked at the world where Mao Sandao was located, and didn't understand the principle that those mortal machines could fly to the sky, this was completely the gap between the two worlds.

"Pangolin Legion, Groundhog Legion, Earth Spirit Cat Legion, Native Chicken Legion, Honey Badger Legion, Flame Wolf Legion, this ...... Good guy, the demon clan is only afraid that it will be hemorrhaging this time, and it has brought all the demon clans with the talent of retreat!"

Fang Tianhua gasped, shocked by the powerful strength of the demon clan, but even more shocked was Ye Bufan's methods. Although those retreat armies are hideous and sharp, they ...... Never been able to break through Aoba Castle's underground defenses.

The pangolin's body is like a tornado, shaped like a drill, spinning and stabbing forward, but when it hits the defensive array, it will only spark, although under the attack of the pangolin army, the defensive array and the entire Aoba Castle are shaking, but the strength of the defensive array has not weakened substantially.

Under Ye Bufan's creation, the defensive array of the entire city is impregnable, and it can obtain a steady stream of spiritual energy replenishment from the four directions of heaven and earth, under the crazy attack of the demon army, when the replenishment speed is far faster than the speed of wear, it is doomed that the opponent's strong offensive is just in vain.

"Click! click!"

The black and white army of honey badgers is even more fierce, with a blood-colored aura all over their bodies, staring at a pair of blood-colored small eyes, and gnawing directly at the light of the defensive cover, under its wild and domineering attack, although the defensive cover continues to fall off one piece after another, it can always be replenished and restored to its original state at the first time.

Therefore, in the eyes of the cultivators of Aoba City, the army of flat-headed brothers who were short in stature and fierce in their eyes seemed to be grinding their teeth in one color, and they were enjoying it very much.

"Boom...... Click...... Sneer...... Zizi ......"

At the same time, the claws of the groundhogs burst out with cold light, their teeth shining, and they attacked the defensive shield deeper underground, each of which was a black light, and every seemingly weak body was a digging artifact, and their goal was to dig through the defensive cover, and they would not give up until they reached their goal, persistent and strong.

"Meow!"

The attack method of the earth spirit cat is much simpler, standing in front of the spacious passage that the other retreating armies have already dug out, the green light in his eyes shines, he opens his mouth and spits out the wind blade, swings his claws to shoot the wind darts, thousands of wind blades and wind darts converge together, turning into a huge wind blade, smashing on the hard defensive cover with a bang, and the ground suddenly shakes.

The Tuxing chicken's beak pecks its claws and slashes its wings, which is menacing and demonic. The Flame Wolf swam from the magma deep underground, absorbing the power of the rich fire underground, and at the same time, condensing all the power of the whole body into a terrifying scarlet scorching flame sword, killing the general.

"Boom, boom......"

Under the crazy attack of various means, the surface of the defensive array was full of fire, scorching heat, the air waves were sweeping, and the gorgeous demonic magic powers were shining, reflecting the dim underground space in a bright light, and the beauty like fireworks covered up the destruction of the rage, almost making the people of Aoba City who saw this scene stunned.

"Hehe, my defensive formation can resist the attacks of ten Yuanying high-level monks at the same time! If I also have the blessing of Yuanying Monk on my side, even if I am a monster one level higher than Yuanying Monk, I can't even think of breaking through the defense of my Aoba City!"

Although the underground demon clan is fierce, Ye Bufan's formation is supplemented with the power of heaven and earth, the cultivation power of all the monks of Qingye City, and there are thousands of inferior and medium-grade spirit stones providing a steady stream of spiritual power, so Qingye City is strong and abnormal for a while, impregnable, and the strong defense is simply outrageous to the demon!

"What kind of formation is this! It's so powerful!"

In the air, the demon clan elder's pupils shrank, and his fists clenched subconsciously. With his eyes, he could naturally see the difference of this formation, he had never thought that the formation could be arranged to such an otherworldly level, and the entire Aoba City was protected in an invisible large round ball, and it was impossible to break the defense from the ground.

"Chaos Body! It must be the Chaos Body's doing!" Soon, the old demon figured out the reason, and his eyes showed determination, and said, "The Chaos Body that has not yet fully recovered is still so terrifying, if it is allowed to really grow...... I'm afraid that my demon clan will not face a big crisis, but ...... Extermination!"

The old monster's gaze penetrated the air and once again landed on Ye Bufan, this seemingly ordinary Terran kid once again impressed him.
