Chapter 77: Earth-Shattering King Zhong

Xiao Yu dug through the ground, and lifted the portable digging machine. After looking at the broken hole, Xiao Yu, who felt that it was too small, placed the digging machine again.

There was another boom, boom, boom, and not long after, another big hole appeared in the sky above the Black Fairy Castle.

After several holes were opened in this way, Xiao Yu felt the ground tremble, and stepped back with the excavator and stepped on the slope that he had dug out with the silt he had dug with his engineering shovel.

boom!

Following Xiao Yu's engineering shovel, he slammed it hard!

The bottom of the deep pit, which had been riddled with holes for a long time, couldn't bear the last straw any longer, and it fell off with a whoosh, bathing the inside and outside of the Black Fairy's castle with a shower of giant falling rocks.

Xiao Yu stretched out his head to look, and saw that the black goblin castle that was filled with smoke and dust had already collapsed, with ruins and boulders everywhere, and the original outline of the castle could hardly be seen.

Xiao Yu noticed that the location of the underground Black Fairy Castle is a cave structure.

It is about twenty meters long, nearly ten meters wide at its widest point, and a little over one meter high, and the rest of it is thick rock walls.

Such a terrain, even if it is dug up, it is difficult to go down!

But...you don't need to go down by yourself.

The wizard apprentices and those black fairies in the Black Fairy Castle also suffered heavy casualties, and only a few strong ones retained part of their vitality by various means.

"It's a giant! It's he who broke the sky!"

The ceiling of the hall where the Black Goblin King is located has long been smashed into open-air ruins. Most of the upper-class Black Goblins next to the throne are wizards or wizard apprentices. They joined forces to block the falling boulder, but because they saw the broken giant Feeling soft and limp for a while.

"How could it come from above?" The vice president only felt that the goddess of luck was moving away from him. Why did the giant take him into the army so unexpectedly?

"No matter what! Fight!" The vice president's eyes flashed with a frenzied look, and he raised his staff.

The wizard apprentices around him saw that the vice-principal was like this, so they all raised their staffs and sent mana to the vice-principal according to the training process.

Relying on the strength of everyone, a gust of wind with a diameter of more than 50 meters on the widest side in the eyes of the villain rushed out of the ground with countless sharp and cold ice flakes.

"It's an ice storm! A simplified version of the first-level witchcraft blizzard!" Inotia felt the wave of witchcraft in the ground, and quickly reminded Xiao Yu.

"I saw it!" Xiao Yu had used all his strength in his eyes, and he could clearly see the large ice storm gushing out of the underground ruins.

"drink!"

After Chaofan, Xiao Yu let out a low shout, and easily raised the digging machine with both hands, aiming the direction of the drill at the hole.

Just as the ice storm was about to reach the exit, Xiao Yu started the machine, and the frenzied turning of his head immediately broke the structure formed by the ice storm's ice and strong wind, and scattered it around.

Xiao Yu noticed the scattered ice storm, which covered the rocks around the cave entrance with a layer of frost.

Even though he was wearing an explosion-proof suit, Xiao Yu could still feel that the air around him was much cooler.

If this kind of witchcraft acts on a defenseless ordinary person, I am afraid it can really cause serious frostbite!

"Come and not reciprocate!"

Xiao Yu leaned the digging machine against the mound of soil, took out the moon chasing crossbow on his back, and at the same time drew out the crossbow, he took out two obviously much larger firecrackers from his portable space and hung them on.

These two firecrackers are not ordinary firecrackers. Their full name is Shaking Earth, also known as Xiangzhong Wang. It is said that the sound is as loud as thunder and can knock out all the fish in the lake.

Xiao Yu had no place to use it when he bought it back then, but when he saw the environment of the underground world, he suddenly had an impulse.

After igniting it, Xiao Yu quickly shot out the crossbow.

"call out!"

The crossbow arrows shot by the moon-chasing crossbow roared past, and pierced in front of the throne of the Black Goblin King with a bang.

The black goblins moved fairly fast, and the accuracy of the crossbow arrows was affected after they were shot, so Xiao Yu didn't aim specifically, and even avoided the arrows for them.

"What is that?" The Black Goblin King on the throne wanted to pretend to be calm when he heard a group of his subordinates muttering.

He also looked at the ridiculously long crossbow bolt in the middle of the original hall, and saw that it was hung with an extremely thick gray cylinder that ten black fairies could hardly encircle.

"It's an alchemy bomb!" The vice president was far away, but he also saw the earth-shattering firecrackers clearly. While retreating instinctively, he loudly issued an early warning.

The upper echelons of the black goblin still knew about the alchemy bomb, and when they saw how big this thing was, they screamed in fright.

"Run!" A black goblin shouted loudly.

"It's too close~ I can't run away! I have to give up on you!" The Black Fairy King no longer hesitated at the critical moment, a black light flashed on his body, and dozens of black fairies around him immediately screamed, and their bodies burst into black mist and enveloped them. Around the throne of the Black Goblin King.

"Dark Witchcraft ~ Sacrificial Guardian!" The escaped vice president's eyelids twitched wildly when he saw this scene. A magic spell that temporarily protects mana!

"Vice-principal! You..." The third-level wizard apprentice who was avoiding the densest falling rocks outside the castle, was about to come but saw the vice-principal running away in a panic, and couldn't help asking.

"Run!"

The vice-principal took a look at the apprentice who impressed him, and reminded him as he accelerated to fly past him.

"run?"

The third-level wizard apprentice was slightly taken aback, and immediately saw the crossbow bolt inserted into the ground about seven or eight hundred meters away.

And that huge cylinder that made him uneasy!

"It's seven or eight hundred meters away from here!" The third-level wizard apprentice thought, "There should be no problem, right?"

at this time!

About two seconds after the crossbow arrow fell...

boom!

An unbelievably loud noise erupted from the cylinder that the crossbow bolt exploded!

These are sounds that are far out of this world!

This is a loud noise that makes the surrounding air seem to have turned into a real body in an instant!

The sound swept every inch of the surrounding space in an instant, it seemed that these sounds had become completely berserk, and they all wanted to rush out crazily!

However, the structure of the underground world makes the space where the castle is located is a cave, and the passages connecting other underground areas are not only in the corners but also very small.

Most of the surrounding areas are surrounded by rock walls, which limit the sound and at the same time enhance the power of the explosion in a disguised form!

The Black Goblin King's sacrificial magic failed to save its life, the black mist was blown away the moment it came into contact with the loud noise, and the Black Goblin King was thrown away by the loud noise like a grain of sand. Disappeared in the echoes.

The rest of the black goblins, wizard apprentices, and even the vice-principals, no matter how fast they escape, as long as they are still in this underground space, they will all be swept away by the loud noise, and they will not be able to resist at all. ripple.

Xiao Yu also quickly climbed out of the deep pit with the digging machine after shooting the arrows. Even so, the roaring and loud airflow rushing out of the hole after the loud noise still made him a little embarrassed and felt a little tinnitus.

As for the onlookers by the pit, none of them were much better, even if Xiao Yu had said hello in advance, they were still so shocked that they fell to the ground one by one, covering their ears, feeling extremely sad.
