"The casualties are a bit high when the war starts directly. I have checked that this demon fortress is poured with magic steel and fire copper. It is extremely strong and it is not easy to attack." William Oak was a little hesitant. In his opinion, anyone who fights the demon is precious and wants to minimize casualties.

"His Excellency Steller, are you proficient in astrology?" Allen asked suddenly.

"I am proficient in all the prophetic schools' magic!" Steller said in a stiff tone.

"Uh, sorry, I didn't mean that." Allen reacted and quickly apologized: "I mean can you summon a meteorite from the Astral Realm for a positioning strike!"

"Your Excellency Ellen wants to use the real meteorite technique?" Hearing Allen's words, the other wizards around immediately reacted. They have been famous for this great killer weapon of the Prophetic School for a long time. There are several versions of this spell. The lowest level is to summon a huge fireball to attack. Its power is not bad and belongs to the category of the Nine-ring spell. As for the real meteorite technique that Allen mentioned is the highest version, which requires the caster to have high astrology knowledge.

And observe the starry sky for a long time, and be very clear about the trajectories of many comet asteroids. Then choose one of them, summon it to the material plane through the space gate, and then pull it to hit the target. The principle of this spell is not difficult, but it is not easy to release it.

The angle, speed, and trajectory of the meteorite entering the material plane must be carefully calculated. If there is a little deviation, it may fail to release it. By then, it will not fall on the enemy's head and smash it on the head...

There are many legendary wizards who have successfully released this spell in history. There is a record of successfully released in a battle between the ancient Wizard Alliance and the Dark Wizard, which is also the most famous example to date.

At that time, the black wizard relied on various black magic human body transformation techniques and other forbidden techniques to create a large number of demonized flesh and blood puppets and undead creatures to siege the Wizard Alliance. At that time, the Wizard Alliance was at an absolute disadvantage in terms of its number of people and advanced combat power. At the critical moment, an academic wizard stood up.

This academic wizard ranks at the bottom among the legendary wizards, but he is proficient in the prophetic school and astrology. Then one night, he cast a spell to summon a huge meteorite. The meteorite fell from the sky and directly smashed the protective barrier attack jointly performed by the black wizard with extremely powerful kinetic energy. In the end, except for the legendary wizards who escaped their lives, all other black wizards, including their army of transformation puppets, were wiped out.

This wizard became famous in one battle. After the war, he became the speaker of the first generation of Wizard Alliance. By the way, this wizard is called Xiu Nicholas Liu.

"Yes, what I mean is to release a real meteorite technique! Just smash the turtle shell of the demon fortress, and then we launch a general attack. In this way, the casualties can basically be ignored." Allen said.

"This is a solution, it's just a real meteorite technique..." Everyone looked at Steller on the side.

"Uh, sorry, I'm not sure." After a brief silence, Steller said expressionlessly.

"Okay." The others looked at each other and gave up the proposal.

"I can summon meteorites, but I need someone to help me calculate the trajectory of the meteorite falling."

"Leave the calculation of the meteorite fall trajectory to me." Allen thought for a while and said, he was going to use a chip to help calculate the meteorite fall trajectory.

"Are you sure?" Steller looked at Allen with a suspicion. You should know that the trajectory of a meteorite fall requires a lot of calculations. The most important time for meteorites to fall is very short. It is very difficult to calculate a large amount of data in such a short time. Moreover, the meteorite traction can only be within fifteen seconds of just entering the material plane. After this time, the meteorite's own gravity acceleration and energy will be so large that it is difficult to change.

The problem of calculating the meteorite's fall trajectory may be difficult for other wizards, but for Allen, it only consumes a little energy.

"Confirm." Allen nodded and said.

"If you are worried, we can do a test first."

"Okay, then let's test it first!" Steller nodded and agreed. You only need to try this kind of thing to know.

"Okay, since we have been sure to use real meteorite technology to attack, we will test it first. If it succeeds, we will directly formulate a combat plan around this spell." Fathier made the decision directly, and the others glanced at Alan and nodded in agreement.

Alan and Steller directly used teleportation spells to arrive at a plain thousands of kilometers away from the Demon Fortress.

"Just here, the Demon Fortress is unaware of it at such a long distance." Alan said, looking at the surrounding environment.

"Okay, let's start!" Steller nodded and said.

"This time I summon a small meteorite first."

After saying that, Steller began to carve rune arrays on the ground. Alan did not mean to help. Everyone had their own spell casting habits, and the same was true for laying out rune arrays. Although there was not much difference, there were still other things in the details. Steller took out the array materials and quickly portrayed them on the ground.

Seeing Steller portraying the rune array, Allen moved and flew to a few kilometers away from here. Allen was preparing to use this place as the target of meteorite. After determining the target, Allen flew back staggeringly.

At this time, Steller's work was coming to an end. Soon a hexagram array with a diameter of about ten meters was arranged. Magic stones were inlaid on the nodes of the hexagram array. Steller then stood up, nodded at Allen, and stood directly in the rune array to start casting spells.

A gentle spell sounded, and the energy around Steller began to gather continuously, and a strong spatial fluctuation enveloped the surroundings.

Then Allen felt a strong spatial fluctuation coming from a height of several thousand meters. The next moment, a huge hole was directly cracked in the sky. Through this crack, you could clearly see that the star world was outside the door.

The next moment, an asteroid with a diameter of about fifty meters appeared in front of me. The asteroid flew very quickly, and then directly passed through the space crack and came to this main material plane.

"Chip calculates the meteorite trajectory!" Allen directly activated the supercomputing power of the chip. For a moment, a large amount of data passed quickly in front of Allen's eyes, and then a three-dimensional three-dimensional picture appeared in front of Allen's eyes.

“The plane deflection is being calculated.”

“The air friction factor is being calculated.”

"The meteorite angle is being calculated!"

"The right side of the meteorite deflects to the left by 15°13 minutes!"

"The rear of the meteorite is deflected by 9°27 minutes!"

......

“Apply secondary acceleration!”

"The target is locked!"

"The meteorite will hit the intended target in 13 seconds."

Allen quickly reported the data one by one. Although Steller was a little suspicious, he still adjusted according to Allen's data. Soon the meteorite met Allen's requirements.

Next, the two saw a meteorite passing by the sky with flames, and then hit the target site accurately. A huge roar came, and then waves of air rushing from the place where the meteorite fell, sweeping all the branches, gravel and stone along the way, including the ubiquitous twisted shadows and various undead spirits.

The ground was hung up by the air waves, and the air waves rushed to less than three meters in front of the two people before slowly dissipating.

"Do you still need to go over and check it?" After a while, when the air waves dissipated and the surrounding energy fluctuations calmed down slightly, Allen turned his head and said to Steller.

"Yeah." Steller's face turned pale and his breath was a little erratic. It was not easy for her to release this spell, but she still nodded.

Then he used the flight technique and flew directly to the target site. All the way, everything around was flattened, and many places were still burning with flames. The two of them quickly arrived at the target site and saw that the original target site had turned into a huge deep pit.

The diameter of the large crater is about three or four hundred meters, and the deepest part is more than ten meters. The temperature of the crater is very high, and there is melting magma inside. After seeing the power of meteorite technology with one's own eyes, Alan secretly stumbled his tongue. This powerful meteorite technology has reached the level of legendary magic. At present, it is also powerful among legendary magic, but the disadvantage is that it is not lacking. This spell is prepared for a long time. When casting, other legendary wizards have enough time to escape the attack range of meteorite magic.

This spell can only be used to attack fixed targets. Although the angle can be adjusted and then the landing position can be changed when casting the spell, time is tight and there is only one chance, so this spell can only attack buildings, fortresses and other targets.

It is basically impossible to kill the legendary wizard with this spell. The purpose of Alan and others is not to use this spell to destroy the Flame Demon Lord Helix, but to destroy the entire Demon Fortress and clear out all the middle and low-level demons. After destroying the Demon Fortress, the remaining Flame Demon Lord Helix is ​​the fish on the chopping board. The five legendary wizards have no chance to escape.

"The effect is pretty good!" Allen looked at the scene caused by the meteorite technique and was very satisfied with its power.

"Your calculation is very accurate." Steller looked at Allen in surprise after checking the target, as if he had known him for the first time.

"Then we will prepare. You take a day off first and wait until tomorrow will return to the best state. Then we will activate the True Meteorite Technique to directly attack the Demon Fortress." Allen looked at Steller, who was weak in breath, and hesitated for a moment.

"This is for you!" He threw a purple crystal bottle over.

"What is this?" As a result, what Allen threw over, Steller discovered was a crystal-looking crystal bottle containing purple liquid.

"Recovery potion can quickly restore magic and mental power." Allen said with a smile.

"When the meteorite technique is released, it can help you recover some strength."
