Heavy Beast Crystal Cannon!
Being able to be labeled as heavy meant that these heavy cannons used a B-grade beast crystal as their energy core.
The cannons were filled with mineral crystals mined from the ground!
The mineral veins under Rock City were fire-attributed. In order to save costs, Rock City's City Defense Army would only order fire-attributed beast crystal heavy cannons from the Federation military!
However, under normal circumstances, the fire-attribute beast crystal cannon was indeed the most direct type of weapon against ferocious beasts.
This was also the convention of each city. The construction of the city defense system depended on the resources that each city had!
It was also for this reason that Rock City's heavy beast crystal cannons were called cannons!
If its energy core was of other attributes, such as lightning, it might be called a heavy beast crystal thunder cannon!
Or perhaps even something like a heavy beast crystal wind cannon.
Each of these cannons was equivalent to a full-powered attack from a B-grade beast!
And these 1,000 beast crystal cannons were the reason why the City Defense Army had 100,000 soldiers against 400,000 mutants!
According to the plan of the City Defense Army's General Staff, before the general attack was launched, there would be a 15-minute bombardment!
These B-Grade Heavy Beast Crystal Cannons had a firing rate of about three rounds per minute. In fifteen minutes of firing, each cannon would fire fifty rounds!
The 1,000 heavy beast crystal cannons would fire a total of 50,000 rounds, and the estimated target was to eliminate more than 300,000 mutants!
This was the data calculated based on the area of the Urban area, the number of mutants, and the strength of the firepower. Under ideal conditions, the killing efficiency should be close to 80%!
In the eyes of the leaders of the City Defense Army, those few Urban area had long been in ruins!
At this moment, they did not feel any heartache at all when they saw Fang Chen demolishing the house!
On the contrary, they felt very happy because every time Fang Chen demolished a house, they could save at least a few rounds of ammunition!
A 15-minute volley of shots was worth real money!
Each time these B-grade beast crystal cannons fired out an ore crystal shell, the value was equivalent to a C-grade beast crystal, which was 100,000 Federation dollars!
The monthly income of most of the lower class civilians in Rock City was only around 1,000!
45,000 cannonballs were worth five billion Federation dollars!
For a city with a population of ten million, this amount of money was not a lot, but it was not a small amount either!
The City Defense Army had already finished adjusting the position of all the cannons!
Seeing Fang Chen demolishing the house and cleaning up the mutants, the three big shots in the command center decided to intervene at this time!
Firstly, it could speed up the elimination of the mutants. Perhaps it could force the Demon Bear Mutants to have a direct conflict with the Nine-tailed Mutants in advance so that they could watch from the sidelines!
Secondly, he wanted to show his fists to the two Mutants to intimidate them.
The two Mutants were fighting in the human city. If they did not express their stance at all, it would be too insignificant. At the same time, it would boost the morale of the City Defense Army!
Of course, there was another reason why he couldn't say it openly.
That was, after this battle ended, the huge number of Mutants killed by the Nine-tailed Mutants could all be blamed on the City Defense Army.
Anyway, those mutants were all smashed into pieces. It must have been the cannon blast!
It would sound better when he reported to the Federation!
The City Defense Army fought against two Mutants!
With the two Mutants having an internal conflict, the City Defense Army sat and benefited.
However, the effect was completely different.
This was actually the real reason why the City Defense Army launched the bombardment.
If all the mutants were killed by Fang Chen alone and they did nothing but watch, even if the crisis was over, the higher-ups would likely pursue the matter. Of course, the main responsibility would be the city lord, Shi Tianzhi!
Boom! Boom! Boom!
Following the command from the City Defense Army, thousands of heavy beast crystal cannons on the four walls fired at the center of the city!
The basketball-sized blazing fireballs drew a perfect parabola in the air and gathered from all directions. Finally, they landed in the mutant Urban area!
This was probably a scene that was unprecedented in the history of the Federation. The heavy cannons on the city walls were firing into the city. Those who did not know better would think that someone had rebelled…
City Lord Shi Tianzhi looked at the scene and could only smile helplessly!
Even if he could successfully survive this mutation crisis, he could forget about the credit. If he did not commit any crimes, he would burn incense.
Bang! Bang! Bang!
Thousands of blazing fireballs descended from the sky and bombarded the ground like raindrops.
The fireball exploded as soon as it landed on the ground, instantly engulfing an area with a diameter of ten meters. However, this was only the area covered by the flames!
Apart from the flames, the mineral crystals that were the main body of the cannonball also exploded when the fire energy was released. These mineral crystals were engraved with the pattern of fragments in advance, turning into sharp fragments that swept across the surrounding 100 meters with a powerful shock wave!
Compared to Fang Chen's blizzard, this scene was much more explosive!
Before the first wave of cannonballs had completely dissipated, the cannons on the city wall had already finished loading and roared again!
Since it wasn't an all-out attack!
Therefore, they had to reserve their firepower!
Therefore, each cannon fired ten rounds at high speed, and a total of ten thousand rounds were fired at the mutant Urban area!
The blazing flames continued to explode in the huge mutant city formed by the three Urban area. Countless mutants were turned into ashes and torn into pieces by the flames!
The neatly arranged buildings were also blasted into pieces one after another, becoming part of the ruins!
At this moment, the density of Mutants in the Mutated Urban area was the most obvious time for the cannon fire to be effective.
The number of Mutants killed in this round of bombardment was estimated to be more than 120,000!
However, if there was another round, it would be good if the number of casualties could be half!
