Thanks to the accumulated experience of Magic Technology and Sakura Stone Technology.

In the past hundred years of the Babel Alliance, the magic crystal cannon, a weapon with attack power equivalent to that of a fourth-level spellcaster, has been operated by fewer and fewer people.

A hundred years ago, when the Magic Crystal Cannon was first developed, this huge and heavy weapon required nearly fifty people to serve it.

This situation once caused the upper echelons of the Babel Alliance Army to give up their continued investment in magic crystal cannons.

There are too many people in need.

There are many, many high-level people in need.

An artillery squad requires at least 4 level 4 casters, 10 level 3 casters, and nearly 30 level 2 casters.

If it weren't for the fact that the magic crystal cannon team, with the assistance of Sakurashi, has a combat endurance that far exceeds that of ordinary fourth-level professionals, the upper echelons of the Babel Alliance's army would have cut off the magic crystal cannon project without hesitation.

However, after a century of development and improvement, the Babel Alliance's magic crystal cannon team now only requires at least 8 people to operate it.

Moreover, it does not require a second-level professional or above. It only requires two first-level and six apprentices. This cannon can exert the power of a fourth-level professional.

From a strategic level, the Babel Alliance's magic crystal cannon can be said to have achieved great success.

It caused the military strength of the Babel Alliance to skyrocket.

Within the artillery range of the magic crystal cannon, no enemy can face this kind of continuous, high-intensity fire coverage.

But.

From a tactical perspective, the magic crystal artillery team without defense personnel is a failure.

The magic crystal artillery group consisting only of mage apprentices and first-level mages was unable to withstand the attack of skeleton soldiers and skeleton warriors dropped by air.

The mage apprentice who learned how to operate the magic crystal cannon in three months has no conditions at all to learn attack spells.

Facing the charging bones of the undead, they don't even know what to do?

The "Magic Crystal Cannon Operation Manual" does not mention what to do if you are attacked by the imaginary undead army of the Dria Empire.

Among the top brass of the Babel Alliance Army, their vision is to build a solid inert stone city wall and city wall defenders to keep the undead army outside the city wall.

Under the female wall of the city wall, they followed the order to operate the magic crystal cannon by tilting and swinging it left and right. Then they input magic power to stimulate the energy of the cherry stone and shoot out the cannon.

When the city walls cannot be defended, they will leave behind personnel and other personnel to evacuate quickly.

The "Magic Crystal Cannon Operation Manual" never described the response scene, leaving these quick apprentices and a small number of first-level mages in a panic.

When the other apprentices in the artillery array were hacked to death by the skeleton soldiers and screamed in pain, they woke up and screamed in terror.

Quick mage apprentices are just like ordinary people.

Facing undead units such as skeleton soldiers and skeleton warriors, they were simply unable to organize any meaningful resistance.

"na, na, geli!"

A first-level mage who broke through the ranks recalled the spells he learned in the military academy and recited the spell several times before reciting the spell.

But no spells appeared.

He only thought about the spell and forgot about synchronizing the body's magic power.

After passing the final exam of the Military Academy, he slowly recalled his diligent practice of assault spells the night before the exam.

Familiar memories appear in my mind.

A fireball the size of a fist appeared in his hand and was launched at the skeleton warrior who had hacked to death the surrounding mage apprentices and was charging towards him.

"Boom!"

The fist-sized fireball exploded with power that was inconsistent with its size.

The charging skeleton warrior was hit by the violent explosion of the fireball and turned into blackened fragments.

Killing the skeleton warrior with one shot made him extremely happy.

The mantra was recited silently in the mouth, and the magic power was in sync again.

A fireball the size of a fist appeared in his hand again.

"Go to hell, you trash!"

"Chi!"

Four penetrating sounds appeared almost simultaneously.

The head of the first-level mage who had not yet launched the fireball had two bone spears pierced through his shoulders.

Two half-meter-long bone arrows shot through his heart.

The first-level mage died on the spot.

The out-of-control fireball disappeared instantly in its hands, just like his life.

The flying sub-keel dragon that hovers a hundred meters in the air fulfills the role of the flying gunship very well.

The skeleton mage and skeleton archer on the back looked at the dead target, and turned their attention to the next first-order mage who was attacking the skeleton soldiers and skeleton warriors.

Bone spears and bone arrows were shot out at the same time, covering them.

Shoot him through the head, shoot through his heart, and bring him death.

The tactic of the undead army descending from the sky to massacre the magic crystal artillery batteries in the city was very successful.

In less than a minute, in the twenty war zones divided by Guo Teng, the Bone Necromancers slaughtered all the members of the magic crystal artillery crew who were almost the same as ordinary people.

Then, it was time for the skeleton soldiers and skeleton warriors on the ground to be slaughtered.

According to the "Army Tactics Outline", the Babel League's army defense tactics are as follows.

High-level defense forces are deployed on the inert stone walls.

Low-level offensive forces are placed in the city.

When the high-level defensive forces resist the enemy's impact, the low-level offensive forces will provide a large amount of firepower from the rear to wipe out all the attacking enemies.

Judging from the current historical situation, the tactics adopted by the top brass of the Babel Alliance Army are correct.

Without air force, a sudden attack from the sky destroyed the low-level kilometer force in the rear.

The defensive tactics of the Babel Alliance can beat the attacking enemy to a bloody head.

Even when the Driya Empire attacked the Babel Alliance in the future, this tactic caused considerable damage to the Driya Empire.

Even if the skeleton soldiers of the Dria Empire are free of charge, this kind of defense still requires a lot of soul power of the necromancers, forcing their souls to wither.

It is a pity that the Babel Alliance is not facing pure Derians.

But a foreigner from a different world.

The airborne tactics of another world have played their true role after being modified by Guo Teng.

Inflict heavy damage on the enemy's closely protected rear military forces.

No one could have imagined that the Boneless Necromancer could be like this.

However, after removing the enemy's weak and important military power, Guo Teng will face a real battle.

High-level defense force on the city wall.

Second-level, third-level, and even fourth-level defensive forces jumped from the city wall and massacred Guo Teng's skeleton soldiers and skeleton warriors.

How did Guo Teng just massacre the first-level mages and apprentices of the magic crystal artillery crew?

How do these city guards target his skeleton soldiers and skeleton warriors?

Guo Teng didn't care that these cannon fodder were slaughtered.

Their meaning is to be slaughtered.

Consume all the enemy's power.

Consumes the caster's magic power and consumes the physical strength of melee combat.

But Guo Teng cannot let these cannon fodder be slaughtered meaninglessly.

All ground skeleton soldiers and skeleton warriors in the twenty war zones were gathered under the four city walls and approached the city guards who massacred them.

Guo Teng needs these cannon fodder to provide time.
