Spell defense towers should be more accurately called spell energy-concentrating launchers. The entire tower is constructed using magic guidance devices. The wizards only need to output their own mental power to activate the magic guidance devices and send out the fixed ones. Spell attack.

High-end defensive towers can be equipped with powerful magical devices, but unfortunately because of the rush of time, it is impossible for them to build better defensive towers. Even these rather simple defensive towers are already the limit of architects. Speed ​​up.

Xiao Lin gently stroked the inky black shiny metal. This is the magic guide device. The so-called magic guide can be interpreted as using magical energy as a guide force. Specific related courses will not be offered until the junior year. Now Xiao Lin He doesn't need to know the principle, he just needs to know how to operate it.

The specific operation actually received special assault training at the architect’s place in the previous two days. The operation method was not difficult. Xiao Lin pressed his hands on the smooth metal plates on both sides of the platform. After a halo flashed, it looked like an iron box. The magic device began to become brighter and hotter quickly.

The launch port of the magical device is also very peculiar. It is not similar to a barrel, but a flat and slender silver metal piece. The inside of the magical device changes quickly, and the metal piece becomes red in the blink of an eye. , And the color kept getting darker, extremely dazzling, and then Xiao Lin only felt the hands holding the metal plate tremble, and then an astonishing wave of air sprayed out from behind the launch pad.

If the top of the defensive tower was not sealed, Xiao Lin would have to be rushed out directly by the air wave, and then he couldn't help but remember that Captain Yu, the architect, seemed to remind them, because it was in a hurry to build the magic defensive tower. Some insignificant things were omitted in the process, such as buffer devices and so on.

After the metal sheet of the emission port shined with enough brightness, the crimson light beam lased out. Like a laser, it exploded directly in the orc infantry formation.

At least four or five orcs were blown into mud on the spot, and their flesh and blood flew across. Even unable to distinguish between hands and feet, their thick-looking armor was as fragile as paper under the attack of the magic tower.

The power of the magic tower scared the freshmen who had never seen this before. Then there was enough curiosity that more people stepped out of the fortress and boarded the defensive tower one after another.

However, the number of magic defense towers is still very small, accounting for less than one-fifth of all defense towers, and more are dominated by arrow towers, which are equipped with launching devices such as large-scale crossbows or continuous crossbows. The attack tower is much inferior to the magic tower, and the attack range is also very small.

However, the attack speed of Arrow Tower is very objective. Relatively speaking, the power of the spell tower is huge, and the operation is really cumbersome. After each launch, the metal piece of the launch port needs to be replaced. The architect Captain Yu and them said that on this kind of low-level spell tower, the metal piece is a consumption. The product needs to be replaced once it is launched, otherwise it will be overloaded and overheated, and the next launch will have a high probability of direct tower destruction.

Xiao Lin didn't dare to take this risk. After the launch, he quickly got up and performed the replacement operation. It was his first time to operate, not to mention the clumsy technique, the metal piece just launched was still extremely hot. Even if clear water is prepared on the defensive tower, it is still quite troublesome to replace each time.

After Xiao Lin took the lead, other defensive towers joined the ranks of attack. The operation of the large-scale crossbow of the arrow tower is much simpler. The huge arrows continue to pierce through the air. Those who operate the crossbow are all optional bow and arrow courses. Of the students, their hit rate is much higher than others, but the mainframe crossbow also has a very inconvenient place, that is, it turns very slowly. Fortunately, the front line stretched very long after the orcs launched their formation, and in many cases they did not need to turn.

To a certain extent, the dense arrows make up for the disadvantage of insufficient single-body lethality. Because a large number of large arrows that can be used for crossbows were found in the ordnance equipment in the warehouse, they did not need to have any idea of ​​economical use.

Although there is a long interval between attacks on the magic tower. But the destructive power of each attack is quite amazing. The attacks of these magic towers are mainly fire energy, and the incidental burning effect is very effective on the grassy plains. The spreading flames will also hinder the orcs' advancement speed.

The people standing on the fortress were not idle either. Everyone was mobilized to attack with all long-range weapons. It doesn’t matter if you haven’t taken an arrow course. The most basic bow and arrow will always be good. As for what you can shoot. It doesn't matter at all, there are thousands of orc infantry, and it looks like the mountains are covered with brown. Shooting arrows at the pile of people, there will always be people with short eyes who will be very unlucky to hit a few arrows.

The orc infantry was also crazy. At least when Xiao Lin witnessed it with his own eyes, he had seen several orcs shot arrows in their bodies, and even one arm was blown away. They were still howling and charging up the hillside desperately.

Judging from the battle scenes, Xiao Lin and the others did suppress the orcs throughout the entire process. Although the wolf cavalry used their bodies to pave all the traps on the way, the following orc infantry did not seem to have expected them. Will be attacked so intensively, or it should be said that the orcs did not expect that Xiao Lin would erect so many defensive towers in just a few days.

The Dawn Academy is undoubtedly fully prepared for this landing operation. The architects who came with the ship are almost all Dawn’s elites. On the one hand, they were ordered to build the resurrection tower, and in order to maintain the fortress, they also didn’t mind sharing. Part of the energy was devoted to building the defensive tower, and the other students knew the difficulty and importance of this monthly exam. No matter how they complained, no one would be lazy when helping with the construction.

Undoubtedly, the orcs may have expected the landing operation of the Dawn Academy, but they did not expect to be so fiercely resisted. They are indeed very fierce. The orcs' charge almost did not stop for a moment throughout the afternoon, and wave after wave was like a tide. They continued to launch offensives, and they had no idea how many corpses had been left on the road.

Xiao Lin couldn't remember how many times he had changed the metal plates. Anyway, the water used for cooling in the tower was used up by him. When the fighting was more intense, he couldn't go back to fetch water. Then he thought of himself. The spell water shield learned before the exam.

This spell uses a water shield condensed by the water element for short-term defense, but the use of the water shield to cool the launching metal sheet is more versatile, and if the water shield is not attacked, it can last for several minutes, which means Xiao Lin even Can be used continuously two or three times.
