Although in the Imperial Academy, Pi Bao Gu has not been in contact with the ghost for a long time, but relatively speaking, it is not too short, after all, there is also a year, the ghost ugly has many amazing deeds among the students, but at the time of the year-end exam, it is the time when the ghost really reflects his strength, in Pi Bao Gu's impression, the ghost always seems to be doing something irrelevant, but it is such a small thing, but it is the end of his step by step to victory, if the ghost always does repetitive things, then it is enough to prove that this matter is deliberately done by the ghost ugly。

Then, this ball of light is definitely not a squib, Pi Baogu watched the third ball of light dissipate, and this thought suddenly sounded in his heart, but his thoughts ended here, the demon army's monster army has begun to charge, many fast-moving monsters have already reached the city wall, only those demon giants are moving slowly behind, Pi Baogu clearly heard the sound of these soldiers swallowing saliva around him, looking at the miserable white faces, the imperial general can only pray in his heart that this magic cannon can exert its power as soon as possible.

The ground shook again, and the wind that had not stopped was even worse, and if it weren't for Pibaugu's quick eyes, I was afraid that one of the soldiers beside him would have fallen off the city wall, "Hold on!" Feeling this abnormality, Pi Baogu shouted, and the surrounding soldiers couldn't help but lie on the wall, and the lighter ones all buckled the city wall, but this wind came quickly, and when it went, everyone in the Luohong Abyss obviously felt a burst of suffocation, and the big mouth couldn't breathe at all, and a soul-shaking feeling came from the magic guide position, and everyone's eyes couldn't help but turn to the same direction.

And this time, another ball of light flew out of the hole of the magic position, but unlike the previous three balls of light, this ball of light seemed to be made of various colors, and the colorful ball of light was the root of making everyone tremble, not only the abyss, but even the prince of the demon clan on the opposite side stood up again, the ball of light was completely different from the previous three balls of light, the first three balls of light were advancing at a constant speed, and then scattered, but this time the speed of the ball of light was getting faster and faster, and there was no sign of dissipation.

"It doesn't seem that the magic guide cannon was fired like this before, is this broken?" The soldier who had seen the magic guide cannon fire before said with some doubts, Pi Baogu also frowned, and couldn't understand why the ghost ugly would say that, but this dangerous feeling has never dissipated, is this the real way the magic guide cannon is fired?

In the magic guide cannon, the ghost ugly's face was pale, and he nodded profusely and said: "Finally finished a cannon, this cannon goes down, the demon army on the opposite side should be able to be wiped out a lot, I don't know if our imperial general has not given an order now, if the effect is not good, I am afraid that this falling abyss will really be lost." The ghost's words were originally said to his master Brooke, but when he finished speaking, after waiting for a while, there was still no movement, and the ghost ugly looked sideways, only to find that Brooke was actually studying a drawing he had redrawn with his head down.

"It turns out that this is the use of the real magic cannon, this idea is really ingenious, it turns out that there is still this function, but it is surprising, there was this idea thousands of years ago, but why is the current record long gone? Time, it is really amazing. After a long time, Brooke sighed and said, when the ghost clown activated the magic guide cannon, he handed him a drawing, and after the two released three light balls, Brooke had a chance to look at the drawing, and now that the magic guide cannon has been fired, Brooke, who has been attracted by the drawing, completely filtered out the ghost ugly's words.

The ghost clown not only solved the damage problem of the magic guide cannon in that half a day, but even explored its true function, the three light balls are the beginning of the magic guide cannon, this link is called calibration by the ghost ugly, that is to say, the purpose of these three light balls is not to cause damage, but to calibrate the target, to prepare for the cannon, of course, this so-called inability to cause damage is relative, for monsters, these magic elements can still cause a certain amount of damage, but according to the madness of the monsters, this damage is naturally negligible, but they have been marked, and the ghost ugly in order to create greater damage, releasing three calibration spells at once.

Almost all the monsters inside and outside the Luohong Abyss have been marked, I'm afraid even the ghost ugly himself doesn't know, the first prince of the demon clan, Blundel, and the phantom demons around him are all within the scope of being marked, and even the people who are marked are not aware of this.

And then the fourth ball of light is the real magic cannon, that is, the cannonball that can kill, but the ghost ugly calls it a measurement, the magic cannon absorbs a limited number of elements, especially dispersed shooting, the dispersion of this element will cause a lot of element waste, and when this colorful ball of light is shot out, the cannonball itself will measure all its own energy and the strength of the attack, and strive to hit the weakness of the calibrated target, killing with one hit.

And the last step is to be ugly by the ghost to give a meaningful name: fireworks, and now is the time for fireworks.

Countless rays of light shot out from this ball of light, this light is very thin, but the speed is extremely fast, before everyone can react, the entire ball of light has turned into thousands of rays of light to envelop the entire Luohong Abyss, and then a silent sound was heard, and a ray of light easily pierced the body of the monster, and those who were stabbed by the monster fell forward with inertia, and on the spider silk bridge of the Luohong Abyss, the monster that attacked frantically fell instantly, almost at this moment, the whole world became silent!

"This power...... It's a bit big!" Ghost Ugly was stunned and looked out of the exit, the magic cannon was installed in the cave, and naturally there would be a hole for people to look at, seeing such a scene in front of him, Ghost Ugly felt that his head couldn't turn around, let alone him, even the zero in his consciousness didn't expect that the power of the magic cannon would directly empty half of the demon army! When Zero took a step back and came to his senses, he said: "Mix the magic elements first, and then separate, what kind of monster is this magic cannon created?" For zero's question, the ghost ugly was also a little stunned, indeed, in the history of more than a thousand years, there is only a record of the magic guide cannon, but which genius invented this thing, but no one knows, I'm afraid that even Master Brooke is so erudite should not know, otherwise he will definitely know that the magic guide cannon will have this kind of use.

"It turns out that this is the real power of the magic cannon!" Brooke then reacted, the hole was scorching, the two people who were roasting were sweating profusely, the cannon barrel had become red, and the two of them were afraid that if it was a little hotter, the cannon would melt away, and the overall calculation of the magic cannon was composed of four cannons, and the effect was far beyond the previous one, it can be said that this cannon went down, at least 100,000 monsters were killed instantly, in the sky above the abyss of Luohong, and because of the power of this cannon, there was an extra vacuum area!

On the city wall, there was a sound of jaws falling to the ground, everyone grew their mouths, their eyes were about to burst, and even their tongues were sticking out, and they didn't even notice that saliva was flowing out, this scene was too shocking, and for a full ten breaths, the entire Luohong Abyss fell into unprecedented silence, and then there were deafening cheers.

In this cheer, the spider silk bridge seemed to be a little unbearable, slowly collapsing downward, and finally in the tense breaking sound, it fell heavily into the abyss, the demon attack on the bridge of the abyss, in this attack of the magic cannon, completely collapsed, and this means that the abyss has once again become an insurmountable moat for the demons!

Pi Bao Gu finally breathed a sigh of relief, feeling the tearing power from the abyss, the imperial general actually felt a little missed, the existence of this power means that the demon clan wants to attack with the spider silk bridge, it takes at least one day, and this day is enough time for the troops to turn around and return to the Luohong Abyss to garrison and defend, the ghost and ugly soldiers' dangerous tricks finally worked, and if he failed, he Pi Bao Gu Ke would really become a sinner for the ages of the Ron Empire and even the entire continent.

"My lord, the troops have already rushed back, what should we do now?" Seeing the angry roar of the demon army on the opposite side of the Luohong Abyss, but the soldiers on the city wall did not have the slightest sense of fear of these monsters and demons in their hearts, Pi Baogu said with a relaxed face: "Concentrate on defense, our task is still very heavy, but at least there is one more day now, you can rest, leave people to sentry, and the rest of the people, rest in place!"

The characteristics of the abyss make it impossible for the air forces of the demons to fly, even the small monsters that specially cut their throats before, after a few attempts, the demons seem to have discovered this, so they continue to use the spider silk of the death spider to catch up with the bridge little by little, and the death spider with the silk is directly pushed into the abyss, and soon the bridge has a prototype, and by noon, the soldiers who have returned to the reinforcements have entered the city, and the spider silk bridge is half built.

Looking at the crumbling but always approaching spider silk bridge, Pi Baogu's face was relaxed, but his brow was slightly furrowed, this bridge seemed to be built a little too fast.

Just as he began to calculate the progress of the bridge, an exclamation suddenly sounded in his ears, and he followed the sound, but saw a group of soldiers focusing their eyes on the direction of the magic guide position, and looking in this direction, Pi Baogu's face suddenly became very strange, because he saw a ball of light flying out of the hole of the magic guide cannon, and the ball of light seemed to be unaffected by the tearing power of the abyss, and actually floated slowly across the abyss as before, and then dissipated on the demon army on the opposite side.

This is...... Another shot?
