The range of 120-mm heavy mortars is up to eight kilometers, in other words, the mortars of a small half of the city can hit the heads of the swarms.

In order to prevent the tragedy from happening again, the command center spared no expense, at least more than 200 mortars fired at the swarm at the same time, including terminal sensitive shells, high-explosive shells, and anti-personnel bombs...... All kinds of shells took turns to fight, some hit at fixed points, some barrage Xu Jin, and some shrapnel flew sideways.

The heavy artillery bombardment caused the defenders' ammunition reserves to plummet, and the swarms that could be covered by artillery fire also suffered heavy casualties, and it was not long before the last giant insect was killed by the shells, and the first round of the swarm came to an end in a barrage of barrage.

Between battles, the defenders quickly gathered the bodies of the martyrs, replenished ammunition and personnel, and prepared for the next round of attacks.

It didn't take long for the statistics to be sent to the forward command.

In addition to the collapse of Building 76, the defenders lost more than 200 people, more than 30 people were missing, and dozens of others were injured to varying degrees.

One fortress building collapsed, several fortress buildings were damaged to varying degrees, and the collapsed No. 76 building blocked the street, losing nearly 300 people...... The forward command believed that all losses could have been avoided if correct judgments had been made while detecting the enemy's situation.

The former commander immediately made a profound review to the Funing command center and deeply analyzed the mistakes in the battle.

Review is not the point, the point is to learn from the lessons and learn from them and not make the same mistakes again.

Everyone knows that the first encounter is only the first round, and there will definitely be more ferocious attacks to come.

The Funing command center was well aware of this, so as soon as the battle ended, several black-painted drones took off in the center of the city and flew at low altitude in the direction of due north.

Satellites cannot penetrate the clouds, reconnaissance can only rely on drones, even if the heavy rain is still falling, even if the lightning has not stopped, the drones must be released.

Several drones flew out of the city from different directions, and one of them was struck by lightning falling from the sky before it could fly out of the city, and the signal sent back by the drone was blurry for a while, but it didn't take long for the signal to stabilize.

Half a minute later, the drone flew out of the city and began to transmit the situation in different directions back to the command center.

Through the lens of the drone, it can be seen that the insect swarm is gathering in the direction of Funing due north, although the sky is full of dark clouds, the insect swarm is still cautious, even if it is gathered together, it still maintains a safe distance.

As a result, the area occupied by the swarm looks so large that the drone can't see the edge of the swarm at all.

The same thought comes to many people's minds: Where did so many bugs come from?

Once the swarm is found, the drone begins to hover above the swarm, sending the detailed coordinates of the swarm back to command.

Soon, the heavy artillery group in the center of Funing turned the muzzle of the black hole hole due north, and heavy 155-mm shells were sent into the chamber.

At the command of the commander, seventy-two self-propelled howitzers distributed in various locations in the city center poured fire on the swarm at a rate of six seconds, and the first round of more than seventy shells flew due north with a piercing scream, flying in the direction where the swarm was located.

Just over ten seconds later, a cluster of blazing flames suddenly erupted in the swarm of insects under the drone lens, countless giant insects were shattered in the explosion, and more giant insects flew all over the sky in the explosion, including both ordinary giant insects and heavy light insects that were heavier than ordinary giant insects.

The city of Funing has a fully equipped heavy artillery brigade, in addition to 72 155-mm heavy guns, there are 12 large-caliber expeditionary rocket launchers.

A single salvo of the heavy artillery brigade was enough to cover a huge area of 300 football fields, but the rocket artillery really did not play a role in the face of the heavy light bugs, so this time only 155 mm heavy artillery fired.

The effect of the artillery bombardment is indeed a cut worse than the salvo of the whole brigade, but it is enough for the swarm to drink a good pot.

The second round of the swarm's assault was ended by heavy artillery before it could begin, and the atmosphere in the command seemed to be somewhat relaxed.

However, the commanders only relaxed, but did not relax at all, under the arrangement of the command center, the drone troops divided into several ways and continued to fly north to further find out the situation of the swarm...... There are not many shells in the reserve of Funing City, but it is okay to bombard it for a few more rounds.

Moreover, there are three warships on the sea, and if necessary, the command center can completely request the assistance of the warships and directly bombard the swarm with naval guns.

The rate of fire of a naval gun is much faster than that of a self-propelled howitzer, and the density of fire of one gun is equivalent to that of an artillery battalion!

In addition to naval guns, warships also have missile vertical launch systems, which have a much higher firepower than naval guns if they are fired in a salvo.

It's a pity that the interception ability of the heavy light insect is too strong, and weapons such as missiles and rockets are not useful at all, so they can only be killed with artillery.

At this moment, I don't know how many people broke out in a cold sweat.

Due to the long range, strong firepower, and good mobility of rocket artillery and missiles, these two weapons have developed rapidly in warfare, while the role of ordinary artillery has become smaller and smaller.

If Funing didn't have this heavy artillery brigade, how would the next battle situation develop?

The density of the insect swarm was not high, and although the cannon killed a large number of giant insects, there were many surviving insects, and they quickly retreated after the bombardment, and it did not take long for them to join up with another group of giant insects.

The drone has been tailing in the air, just in time to come and send the position of the giant insects back to the command center.

However, the command center did not immediately order the artillery group to open fire, but ordered the artillery group to stand still.

It's not that the command center doesn't want to shell, but the distance of the swarm is a bit far, and the swarm is particularly scattered, at this time, the artillery effect, I'm afraid it will be worse than the first round of shelling, rather than wasting shells in vain, it is better to wait for the swarm to attack, and then give the swarm a ruthless one when the density increases.

With the terrain in the north of the city, the density of the swarm will definitely increase with the distance, if it is as sparse as the screen all the time, then there is no need for artillery bombardment, and the soldiers on the front line can solve the battle directly with guns.

Although the swarm did not plan to attack, the Funing command center did not intend to wait forever, and the hovering drone quickly found the heavy light insects in the swarm.

At this time, the heavy artillery group had been replaced with laser-guided shells, and several cannons opened fire one after another, and the shells flew straight north...... Only a few guns were not yet a salvo, and they were not at all on the same level as the previous shelling.

But that's not how the account is calculated, when the cannonball is about to fly over the swarm, the drone irradiates the heavy light insect on the ground with a laser at the right time, and the cannonball in the air accurately captures the target position and immediately rushes to the ground heavy light insect.
