Above the Seven Towers

Down the hillside of the village, the soldiers of the second tier and the mage class had trouble surrounding the enemy ’s last stronghold. There is actually a middle-level mage in this stronghold, a low-level mage and the archer of seven or eight are still resisting the corner. The ice storm released by the mid-level mage made it impossible for the two squads who stepped forward to attack, and also caused a dozen or so fighters to be seriously injured.

The second platoon leader believes that a strong attack may pay a considerable price. Now is the time for the Master Class to start.

In addition to the opponent's magic and bow and arrow range, the Master Class is ready to cast spells.

Including Wu Qi, the nine masters in the Master Class did not wear traditional robes, but wore the same camouflage clothes as the surrounding guards, but each of them wore a distinctive armband. It is a pattern composed of five stars, a staff, and two olive branches.

Most of these young people are traversers in the **** team, and their excellent magic talents have allowed them to grow into low-level wizards in a very short time, and then they were selected from the army and became pure caster units dedicated to magical attacks.

The squad leader of the Master Class stands in the middle, with one person standing in each of the four directions of southeast, northwest, and four others further away standing in the four directions of southeast, southwest, northeast, and northwest, forming a square inlay around the squad leader. Set of diamond-shaped positions, every two people are separated by more than one meter. Wu Qi is standing in the southwest. Because Huang Zheng is not there, they can only use the formation of nine to release the joint fireball technique.

The skill of joint casting is naturally available in this world, but it is often used by several mages to perform large-scale magic. They keep a distance from each other when casting, so that the magic power will not interfere with each other. After the casting is successful, the various parts of the magic are put together to produce an effect. Just like some magician is responsible for making a big fireball, another magician is responsible for pushing this fireball with the wind. The last mage is responsible for detonating it at a specific location.

However, it has never been the practice of using multiple mages to release the same magic to enhance the output power. Because under normal circumstances, two mages cast a spell at close range, which often leads to mutual interference, which greatly reduces the magic effect, or simply makes the magic fail.

However, Mao Kai of the magic group accidentally discovered that when exploring the magic interference, the magic interference of the same kind of magic may find the opposite change under different angles. Not only does it not weaken the magic effect, but also strengthens the magic power in power, time or range. One plus one is greater than two.

He called this new discovery a magic resonance. So he took the most common fireball technique as a sample and began to study the resonance position of this magic.

He refers to two people casting a spell together as two resonances, and three people together as three resonances. Mao Kai spent four hours to calculate three resonances, and eight hours to calculate four resonances, but it took three full days to reach seven resonances. In the end, it took a full month and a half to calculate the fireball technique to ten resonances.

According to calculations, the Ten Resonance can already increase the explosive power of fireball by 3 times, the range by 1.7 times, and the magic piercing effect by 0.8 times. You know, this is a three-fold increase on the basis of the destructive power of ten fireballs. It is a leap from a knife to a giant axe. In this case, the low-level magic of the combined cast is even more powerful than many high-level magic.

However, this hard work for more than a month was not in vain. Mao Kai and a research team composed of seven or eight teachers and students from mathematics, physics, and computer majors summed up a set of algorithms during the calculation process. With this algorithm, most magic can automatically calculate to ten resonances as long as it has six resonances.

Although the calculated result is not the final version, and various adjustments and changes are required, the time for calculating the resonance position is greatly reduced.

Of course, the more complex the magic, the more time it takes. Basic magic like fireball will take a month and a half. If it is a complex magic like the heart of fear, it may not be clear for ten years. And those two resonances have to calculate a week of advanced magic, and it is simply not realistic to rely on manpower to develop ten resonances. But with the help of this algorithm, with the help of computer software, it is really feasible.

Mao Kai's discovery aroused great interest from the guards. Wang Jiyuan, full of ideas about modern warfare, had long wanted to put the magician into the contractual combat system. Magic Resonance inadvertently opened the door to using joint casting as the basic combat method for army mages.

However, although there is theoretical support, as the spellcaster itself, it is necessary to cooperate closely when casting spells, and the movements must be synchronized, which requires a lot of training to achieve. Therefore, although Mao Kai has developed ten resonances of seven or eight spells. However, it took Wu Qi and others a month to practice the fireball technique to 80% synchronization rate and the sleep technique to 50% synchronization rate.

Today, this is the first time they have actually put this tactic on the battlefield.

"Fireball, preparation, three, two, one, chanting." With the squad leader's password, nine people began to chant together.

The so-called magic spell has no effect on its own, it is just a way to help the mage outline the model. Essentially, it is the same thing as the old man's formula (Note). Therefore, the inheritance of different magic towers to the same magic formula is likely to be different, and each mage will adapt the formula according to his own needs. For those very skilled mages, naturally there is no need to cast spells.

But spells are very useful in joint casts. According to the mantra, the rhythm of all mages is easier to synchronize, and the effect of casting spells will be much better.

Fireball is still in the process of preparation, and there is a trace of magic swimming between these mages, making them seem to be in a red gauze.

When the last spell in the mage's mouth ended, nine fireballs flew out of their hands together. Under the traction of the surrounding forces, they merged together and became a super fireball. This fireball is like a meteor, drawing a bright arc in the sky, spanning a distance of nearly two hundred meters, and falling on the enemy's stronghold.

With a loud noise, the fire was blazing, and the dust rolled. The enemy stronghold and the people inside were blown away by a fireball, and even the mid-level mage was shattered into shields and burned into coke. Only one of the most powerful grudge warriors stumbled out of the sea of ​​fire. He was scorched black, and his body was still burning. He fell down without a few steps, and there was no sound.
