At the foot of the hill in the village, the soldiers of the second row and the mage squad encountered trouble when they surrounded the last enemy stronghold. There was actually a mid-level mage in this stronghold, and a low-level mage and seven or eight archers were still resisting. The ice storm released by the mid-level mage made the two squads unable to move forward, and also caused more than ten soldiers to suffer serious injuries.
The second platoon leader thought that a strong attack might come at a high price. Now was the time for the magician squad to take action.
Outside the range of the enemy's magic and bows, the mage class is ready to cast spells.
Including Wu Qi, the nine mages in the mage class did not wear traditional robes. Instead, they wore the same camouflage uniforms as the surrounding guards. The only difference was that each of them wore a unique armband with a pattern of five stars, a staff, and two olive branches.
Most of these young men were time travelers from the guard team. Their excellent magical talent allowed them to grow into low-level wizards in a very short time. They were then selected from the army and became a pure spellcaster force specializing in magical attacks.
The squad leader of the mage class stood in the middle, with one person standing in each of the four directions, and four more people standing in the southeast, southwest, northeast, and northwest, forming a square nested diamond formation around the squad leader, with about one meter between each person. Wu Qi stood in the southwest position, and since Huang Zheng was not there, they could only use a nine-person formation to release the joint fireball technique.
The technique of joint casting does exist in this world, but it is usually performed by several magicians working together to cast 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 spell is successfully cast, the various parts of the magic are pieced together to produce the effect. It is like one magician is responsible for making a big fireball, another magician is responsible for pushing the fireball with wind, and the last magician is responsible for detonating it at a specific location.
But there has never been a practice of using multiple mages to release the same magic to increase the output power. Because under normal circumstances, two mages casting spells at close range will often cause mutual interference, greatly reducing the magic effect, or even causing the magic to fail.
Mao Kai from the magic group accidentally discovered during his exploration of magic interference that the same type of magic interference may have opposite changes at different angles. Not only will it not weaken the magic effect, but it will also enhance the power of the magic in terms of power, time or range, achieving the effect of one plus one being greater than two.
He called this new discovery Magic Resonance, and he used the most common Fireball spell as a sample to study the resonance position of this magic.
He called two people casting a spell together two-digit resonance, and three people casting a spell together three-digit resonance. Mao Kai spent four hours to calculate the three-digit resonance, and eight hours to calculate the four-digit resonance, but it took him three whole days to calculate the seven-digit resonance. In the end, he spent a whole month and a half to calculate the fireball spell to the ten-digit resonance.
According to calculations, ten resonances can increase the explosive power of the fireball spell by 3 times, the range by 1.7 times, and the magic piercing effect by 0.8 times. You have to know that this is based on the destructive power of the ten fireball spells, and it has increased by 3 times. It is simply a leap from a knife to a giant axe. In this case, the combined low-level magic is even more powerful than many high-level magic.
However, the hard work of more than a month was not in vain. Mao Kai and a research team of seven or eight teachers and students from mathematics, physics and computer science majors summarized a set of algorithms during the calculation process. Through this algorithm, most magic can automatically calculate to tenth digits as long as the six-digit resonance is calculated.
Although the calculated result is not the final version and will have to undergo various adjustments and changes later, it greatly reduces the time for calculating the resonance position.
Of course, the more complex the magic, the more time it takes. A basic magic like Fireball takes one and a half months. A complex magic like Heart of Fear may take several years to calculate the tenth resonance. And those advanced magics that require two resonances take a week to calculate. It is simply unrealistic to rely on manpower to develop ten resonances. But with the help of this algorithm and computer software, it is really feasible.
Mao Kai's discovery aroused great interest in the guards. Wang Jiyuan, who was full of modern warfare concepts, had long wanted to put magicians into the joint combat system. Magic resonance inadvertently opened the door to joint casting as the basic combat method of military magicians.
However, although there is theoretical support, as a spellcaster, it is still necessary to coordinate closely and synchronize the movements when casting, which requires a lot of training to achieve. Therefore, although Mao Kai and his team have developed ten-digit resonance for seven or eight spells, it took Wu Qi and his team a month to practice the fireball spell to an 80% synchronization rate and the sleep spell to a 50% synchronization rate.
And today, it was the first time that they actually put this tactic onto the battlefield.
"Fireball, ready, three, two, one, chant the spell." Following the squad leader's command, the nine people began to chant the spell together.
The so-called magic spell itself has no effect, it is just a formula to help the magician outline the model. It is essentially the same as the formula of the old man Hua Ding (note). Therefore, different magic towers may have different formulas for the same magic, and each magician will adapt the formula according to his own needs. For those very skilled magicians, there is naturally no need to chant the spell.
However, spells are very useful in joint casting. By performing actions according to the spell, the rhythm of all mages can be more easily synchronized, and the effect of casting will be much better.
While the fireball was still being prepared, a trace of magic power flowed between these mages, making them seem as if they were in a red gauze tent.
When the wizards finished their last spell, nine fireballs flew out of their hands and merged together under the pull of the surrounding forces to form a super large fireball. This fireball was like a meteor, drawing a bright arc in the air, spanning a distance of nearly 200 meters and landing on the enemy's stronghold.
With a loud bang, flames shot out and smoke billowed. The enemy's base and the people inside were blown to ashes by a fireball. Even the mid-level mage had his shield shattered and burned to charcoal. Only the most powerful warrior stumbled out of the sea of fire. His body was charred and still on fire. He fell down with a bang after walking a few steps, without a sound.
