No matter how fun the game is, there will be times when it is boring, I don't know how long it has been, and I don't know how many times the demon has been bombarded, if not thousands, but hundreds, Gu Renyun was tired and estimated that this demon must be dead, so he stopped.

The light dissipated, and I saw a "corpse" with closed eyes, tattered wings, and a body full of holes, and a "corpse" with magma flowing out of it falling downward. Fall.

"This demon's body is so hard! I can blow up dozens of meters of land with a single fireball, but now that so many spells are smashed on the opponent, he can guarantee that the whole corpse will ......" Gu Renyun was very surprised, and then he shook his head: "Forget it, leave him alone, let's go find the castle tower, I almost forgot about this task...... Well, the direction this monster came from is the location of the castle tower. ”

Gu Renyun flew in the direction where this Ballomo came from......

At this time, the "corpse" that Gu Renyun thought of suddenly opened his eyes in the air, his eyes full of fire only anger, he quietly adjusted his posture and stopped falling, stretched out his hand, and a flaming sword appeared in his hand out of thin air.

He glanced at Gu Renyun with a hideous look at the corner of his mouth, and recited a spell in his mouth, summoning a wind around him, which could not only speed up his flight, but also reduce the sound he made when he flew.

Then the tattered wings flapped slightly, and his body flew towards Gu Renyun like an arrow from the string, but what was surprising was that unlike when he came, this time he could be said to be silent—obviously, he was preparing to sneak attack!

Demons are chaotic and evil creatures that they generally don't think of...... Or that it is simply impossible to perform a tactic that requires a high degree of discipline such as a sneak attack, with the exception of the Abyss Lord, a demon of this level who can already overcome his instincts when necessary.

Kuksar felt humiliated - he was bombarded for most of the day by a person who made him feel terrible by sending children away, and judging from the other party's energy, it was clear that a spell could destroy him, but the other party used countless spells that were not even basic spells to bombard him for most of the day......

Although his injury was not very serious, he looked extremely embarrassed, which was equivalent to slapping someone in the face, how not to make him feel humiliated!

And this humiliation can only be cleansed with blood - either his, or mine!

……

Not long after Gu Renyun flew, suddenly a majestic mountain surrounded by light appeared in front of him, and at the foot of this high mountain and in the sky were densely distributed demons, these demons were densely packed and wasted like the ocean, roughly estimated that there were not hundreds of thousands of demons, and these demons were all desperately attacking that thin layer of light, and colorful explosion traces appeared one after another on the light mask.

And with Gu Renyun's arrival, the demons over there also seemed to have discovered Gu Renyun's traces, and some of the demons flew towards Gu Renyun......

"Although it's a bit much, the quantity shouldn't be a problem, but I don't know how many Abyss Lords there are......" Gu Renyun looked at this demon sea and muttered to himself, he is now like a humanoid nuclear bomb, the quantity is no longer bothering him, what he is afraid of is the quality, if there are a few seventy or eighty level Abyss Lords, he will only have to run away.

After all, he doesn't know any high-level spells at all now, although he has powerful skills, even low-level spells can cause great power, but in the face of minions to crush it, it is a bit insufficient to deal with real masters.

"This time I'm going to try to play a big one!" Gu Renyun made a move with his right hand, and a fireball appeared in his hand, and this fireball did not immediately radiate out as usual, but kept injecting energy into this fireball...... And this fireball had his input energy regardless of the cost, and it immediately became as big as a balloon.

By the time those flying demons flew not far in front of Gu Renyun, this fireball had already become the size of a 30th-story building, and Gu Renyun was as small as an ant compared to this fireball.

At this time, even the chaotic demons hesitated in the face of this huge fireball, and no longer dared to take a step forward in the same place, and even the demons attacking the castle tower in the distance couldn't help but stop and looked at this fireball......

"Almost!" Gu Renyun looked at this huge version of the fireball with pride in his heart, just looking at it was terrifying, and he didn't know how powerful it would be......

"Hey!" Gu Renyun swung hard, and the huge fireball suddenly flew towards the middle of the demon sea, and in an instant, chickens and dogs jumped, and the demons could run, fly, and move in space, and the dark red ocean instantly turned into pieces and fled.

"Boom!" The fireball, which was larger than the mountain in the nearby castle tower, smoothly scorched the flying demons along the way, and then crashed into its destination, making a sound of landslides and cracks, and the red flames exploded, and the air waves rose into the sky, and the earth shook violently like an earthquake.

After a long time, he calmed down, and Gu Renyun couldn't help but be so shocked that he couldn't speak with his mouth wide open......

In addition to the basic destruction of the space teleportation technology of the demons on the earth, eight out of ten in the sky have also been removed. Nine, in short, it does not constitute a threat.

And the terrain ...... It can only be said that Gu Renyun created a basin, and there is magma flowing out of this basin, as if the earth was injured and shed blood.

But what really shocked Gu Renyun was...... The demons attacked the castle tower's mountain protection formation, which had not been broken for several days...... It's broken!

This is also understandable, the demons are already besieging the castle tower, that is to say, the demons are near the castle tower, plus the castle tower formation has lasted for so long, it is the end of the strong crossbow, Gu Renyun came so fiercely, even if it didn't hit directly, but the aftermath damage caused by too close was not small.

This obviously shocked everyone and the demons, whether it was the people of the castle tower or the remnants of the demons for a long time, they had never seen such a rough, huge, and incredible spell.

For example, in the case of demons, if they want to destroy so many troops at once, they may use meteorite, although meteorite has many disadvantages - such as slowness! When the meteorite falls, eighty percent of the enemy is almost gone......

But the meteorite technique is only a mortal-level spell, and the energy spent to use it is estimated to be less than one-ten-thousandth of the huge fireball just now, as long as there are a few more moves, covering a radius of ten miles, the same effect can be achieved to destroy all the troops - of course, in fact, if someone does this, someone will cast the banishment spell to banish the meteorite to another dimension...... But this is a spell, and it has advantages and disadvantages, depending on how the caster uses it.

The demon had never seen such a simple and brutal use of energy to smash them, which left them in a complete state of stupor......
