The piercing scream resounded in all directions, and the heavy light insects that were locked by the cannonballs had no time to dodge, and were directly hit by the cannonballs falling from the sky.

With a loud bang, the heavy light insect that was still showing off its might just now disappeared.

This cannon sound was just the beginning, and then one after another cannonballs fell from the sky, killing the heavy light insects in the swarm one by one, and in a short time, dozens of heavy light insects had been eliminated, and hundreds of other kinds of giant insects were killed in the explosion.

There are not many heavy light insects, and they are not at all conspicuous when they are scattered in the swarm of thousands of insects, and the same is true for the cannonballs that fly down, falling into the swarm.

There were so many bugs that the explosion only stirred up a little bit near the explosion point, and at a slightly distance, they turned a blind eye to the explosion and did not hear it.

I don't know if the explosion stimulated the nerves of the bugs, or if the bugs were ready to attack for a long time, the swarm suddenly moved and rushed towards Funing at an extremely high speed.

It may be because the heavy light insects in the swarm are all cleared by the cannonballs, and without the drag of the heavy light insects, the speed of the swarm is obviously faster, but it is limited to the terrain in the north of Funing, and the closer to Funing, the higher the density of the swarm.

The atmosphere in the Funing command center immediately became tense, and the commander immediately ordered the heavy artillery brigade to get ready.

Soon after, the swarm approached the north of the city, and the time was ripe for the shelling, and the commander gave the order, and the heavy artillery brigade opened fire again, and the dense shells fell into the swarm.

At this time, the swarm has entered the range of heavy mortars, and some heavy mortars in the north of the city have also joined the ranks of shelling, as the swarm gets closer and closer, more and more mortars join the shelling, the gunners have taken their skills to the extreme, and the shells are discharged and dropped at the same time, Xu Jin's barrage is like an iron wall, rampage in the swarm, tearing up all the giant insects that dare to approach.

The shelling lasted for half an hour, and the swarm never managed to pass through the barrage, and I don't know how many giant insects fell on the way to the charge.

After the shelling, the battlefield was full of craters, corpses and severed arms of giant insects, and dying giant insects could be seen everywhere.

The second round of the attack of the swarm was directly crushed by the artillery, but the shelling that lasted for half an hour also consumed the ammunition of the heavy artillery brigade.

There are only so many shells, and one less to hit, and if the swarm holds out a little longer, the heavy artillery brigade will be in a dilemma of running out of ammunition.

The situation with the 120 mortars in the north of the city was even more serious, and the shells were everywhere, and only a few mortars that were farther away from the front could still retain some of the shells.

Through the footage transmitted by the drone, it can be seen that after two consecutive rounds of attacks, the swarm in the direction of due north is still very large, and the third round of attacks may start at any time.

However, the heavy artillery brigade did not have many shells left, and the large-caliber shells could not be replenished in a short time, and several commanders quickly agreed: the remaining artillery could no longer be wasted at will, and it must wait until the critical moment before it could be used.

The torrential rain gradually subsided, turning into a drizzling rain, and the insects stepped on the stagnant water on the ground to launch a third round of attack.

The fighters in the positions had long been ready for battle, no one spoke or flinched, everyone stayed in their positions, silently waiting for the arrival of the swarm.

Everyone already knows that this time there is no heavy artillery cover, and the cruel reality is like a mountain pressing on the hearts of the soldiers, so heavy that it seems that the air is about to freeze.

The swarm broke through the night, appeared in the field of vision of the soldiers, and then entered the range of the rifle, the commander gave an order, everyone pulled the trigger at the same time, the entire defense line was full of firepower, countless bullets flew head-on to the swarm, and the giant insects that rushed to the front were knocked down one by one by the dense bullets, but the giant insects behind still rushed up regardless of it.

The lethality of the bullets was far inferior to that of the shells, and the swarm rushed closer and closer, and soon entered the range of the grenade launchers, and the grenade launchers on the defensive line opened fire in unison, and countless grenades fell on the front line of the swarm, killing and wounding countless giant insects.

The giant insects are not vegetarians, after they rush to a certain distance, they suddenly spit bone spurs at the human position, and the sharp bone spurs instantly crossed a distance of more than 100 meters, most of the bone spurs missed, and only hit the wall near the shooting hole.

However, the power of this thing is not weak, and every bone spur burrows deep into the wall, at least a third, and some can even reach a half!

Only a handful of them hit the shooting hole directly, but each bone spur that hit penetrated the defender's body, bringing a rain of scattered blood.

Just as the two sides were engaged in a fierce confrontation, a group of heavy light insects appeared behind the charging swarm, their pace was heavy and slow, and as soon as they appeared, they aimed at the fire points of the human position.

A fine light flashed, and a single salvo destroyed more than a dozen firepower points.

This scene was sent back to the command center by the faithful drone, and in the face of this situation, no one mentioned the matter of saving shells, and the command center immediately ordered the heavy artillery brigade: eliminate the heavy light insect at any cost!

So the artillery of the heavy artillery brigade fired again, and the shells flew over most of Funing and smashed heavily on the heavy light insects behind the swarm.

At this time, the situation on the battlefield is very delicate, and the defenders, giant insects, heavy light insects, and heavy artillery each have their own goals and tasks.

In the face of this scene, many commanders felt that what they were dealing with was not a swarm, but an armored cluster of humans, or an armored cluster with particularly strong anti-missile capabilities!

The Heavy Light Worm is like a tank, and the Giant Worm is like an armored car, and the two complement each other, just like the armored assault tactics of humans.

Due to the special tactics of the giant insects, the torrent of human steel has not yet appeared on the battlefield, and it is impossible for aliens to draw inspiration from the battlefield.

But there are so many humans who have fallen into the hands of aliens, and so many people have been transformed into worms, it is impossible for aliens to put ready-made resources and not use them, and they must have known the various tactics of humans in the mouths of wormmen.

Therefore, it is not surprising that the aliens have developed the coordination tactics of two giant insects, light and heavy.

There are more heavy light bugs than expected, and if you die, you will replenish one, and until the heavy artillery brigade runs out of shells, the drone can still see dozens of heavy light bugs.

The Funing command center was deeply aware that the small arms in the position could not stop the swarm, and it was necessary to create an opportunity for the defenders to crush the third round of the swarm's attack.

But how do you create opportunities?

The commanders quickly agreed: saturation attack!

It only took a few minutes for the command center to come up with a battle plan and immediately report it to the northern capital.

Soon after, the saturation offensive began, with Funing City as the center, the heavy artillery units within a radius of several hundred kilometers received the combat order from the northern capital at the same time, and the units immediately adjusted the firing parameters and opened fire in the direction of Funing due north according to the order and time specified in the order.
