On the steel city wall, all the long-range firepower was fully opened, and countless Force bombs broke through the rain curtain to draw dazzling lights in the air, frantically shooting towards the swarming beast tide, and the wild beasts that rushed in the front row were instantly pierced by the flying Force Bombs, and the Force Bombs penetrated the front row of wild beasts and still maintained high-speed flight, until the warhead was deeply immersed in the body of another row of wild beasts closely behind, and then it was completely detonated.

The force of the Force bomb's detonation was enough to inflict heavy damage on the desolate beasts within a radius of ten meters around them, and the shattered bodies of the exploding beasts did not make these desolate beasts timid, but instead aroused the most brutal wildness in their hearts.

In the face of the dense long-range firepower of human beings, the charge at the forefront belongs to the cannon fodder-level desolate beasts, this kind of tall, agile speed, but no attack power of the desolate beasts, is the best cover, a short 100-kilometer charge, human long-range firepower almost wiped out the cannon fodder-level desolate beasts, a large number of cannon fodder-level desolate beasts that lost their combat effectiveness and collapsed to the ground, will also be trampled to death by the torrent of the desolate beast army.

However, the death of these cannon fodder-level desolate beasts in groups was exchanged for the main force of desolate beasts coming to the city.

The solid steel city wall is enough to withstand the impact of this level of desolate beasts, and the desolate beasts that charge in the front row have no time to stop, and the speed of their galloping makes them act as victims of the first wave of frontal impact on the steel city wall, and the steel thorns more than ten meters long instantly penetrate the bodies of these desolate beasts, and then the beast tide that follows one after another will push the desolate beasts in the front row into the dead steel thorn city wall again.

Within a hundred meters in front of the city wall, it can be called the purgatory of wild beasts, countless wild beasts that have been squeezed and trampled and deformed, and the last life is lost here, stepping on the corpse of the wild beast, the best at jumping a kind of Kun wild beast - grub, along the smooth steel city wall, directly climbed on the city wall of nearly a thousand meters.

The grub belongs to the B-class melee beast, its size is similar to that of a human, and the main means of attack is his two pairs of clamps, the bite power of the clamps can easily clip the titanium alloy steel plate after ten centimeters, and the outer deck of the ordinary strong mecha cannot resist the attack of the grub at all.

Thousands of grubs climbed the steel city wall, and at this time, the mecha legions that received the order entered the city wall one after another, and the bloody hand-to-hand combat scene instantly began.

The mecha monks of the Xia family were in groups of fifteen and began to fight to the death against the desolate beasts on the city wall. The defensive mecha monks are at the forefront, the Force defense skills are opened without reservation, and the huge defensive Force equipment is displayed one after another, and they are not afraid to face the desolate beasts that are several times more than their own, and effectively contain them.

The strong breeding mecha monks in charge of defense were generally five people, and they successfully resisted the simultaneous attack of more than a dozen desolate beasts. Immediately followed by the melee mech monk, the melee mech monk at this moment

The role played was extremely huge, on the city wall, seventy percent of the desolate beasts that climbed up were killed by melee monks, and among the fifteen-person strong breeding mecha group, the melee mecha accounted for seven.

Standing at the back of the group are the range-shooting mechs and the control or healing mechs. Long-range shooting monks are generally two people, and due to the extremely small number of mecha monks in the Xia family's control system and healing system, each mecha team of the Xia family is only allowed to be equipped with one auxiliary mecha monk, which also leads to an important factor in the high casualty rate of the Xia family's mecha monks.

The long-range shooting mechs barely had much energy to deal with these desolate beasts climbing the city walls, as most of their energy was focused on the sky. The overwhelming toothed bats, using their sharp minions and teeth, frequently launched attacks on the strong mecha monks on the city walls.

The toothed bat is a C-class desolate beast, and its attack power is similar to that of the War Spirit Monk's attack, and its sharp claws can effectively destroy the monk's strong breeding mecha. The Xia family's strong breeding mecha is uniformly purchased from the "Ink L-07" series of the military of the Zonghe Imperial Government, which is a cost-effective strong breeding mecha with excellent attack and speed increase, but the defensive performance is insufficient.

Under the high-frequency attack of the claws of the toothed bat, the outer titanium alloy steel plate of the "Ink L-07" mecha is easily scratched, thus injuring the electronic components and pipelines inside the strong breeding mecha. As a result, the performance of the strong breeding mecha in all aspects is not functioning normally, and even paralyzed.

In this life-and-death battle, if the Breed Mecha can't operate efficiently, all that awaits is death.

After investing 300,000 and half of the strength of the mecha legion, the Xia family basically stabilized these relatively short, agile and strong climbing beasts, and the nearly 500,000 beasts that climbed the city wall could not exert much damage at all under the dense vitality, and the unilateral slaughter caused the number of wild beasts on the city wall to decrease sharply.

Similarly, the death rate of the Xia family's mecha legion reached its peak, and in less than half an hour, the number of Xia family's strong mecha killed exceeded 20,000, and this was only the beginning of this decisive battle.

"Boom~~"

Huge tremors and deafening roars resounded throughout the battlefield. The three most elite armies of the Desolate Beasts, under the leadership of the Beastmaster-level Starry Sky Beast One-Horned Heavenly Bull, began to attack the weakest part of the Iron Fury Castle's steel walls.

In the middle of the steel city wall and at 45° on both sides, three steel gates with a width of 520 meters were installed using a clamp slot occlusion structure, which was intended to benefit mankind

The heavy land machinery unit is easy to pass, but at this moment it has become the deadliest place in the entire steel wall.

In the face of the attack of the "star" scale star beast, the ordinary human heavy mecha force is useless on the interstellar battlefield of this level, and the "starweight" scale cannon fodder level desolate beasts have reached the combat effectiveness of human warmasters, and the heavy mecha force can only be a one-sided slaughter in the face of this brutal individual force dominant desolate beast attack.

"Boom~~"

At the main gate of the steel city wall, all the desolate beasts naturally gave up an open field five kilometers wide, and the 200-meter-high star ox desolate beasts were hitting the steel city wall in a continuous cycle.

Xingniu is a hard-armored power-type Kun beast, and its defense ability has reached the S level, and the damage to him from ordinary Force bullet attacks is minimal, and only a strong breeding mecha monk above the human realm can break the defense with a full blow.

The consequences of the gate of the steel city wall being broken head-on are unimaginable, the loss of the steel city wall, a military strategic fortification defense, tens of millions of desolate beasts rushed into the steel castle, and the two million mecha legions had to confront head-on, in the face of the absolute superiority in numbers, the strength of this desolate beast army, the Xia family's strong breeding mecha troops are likely to be wiped out, and there are also three million ordinary heavy mecha troops inside the steel fort, with the breakthrough of the steel fort, it will inevitably become the ration of this desolate beast army.

Xia Weining received the order to attack, and Xia Weining, who had the strength of a four-star Venerable, was the deputy commander of the Seventh Regiment of the Second Mecha Legion. He, like the other two other two deputy commanders of the Second Army, received the same order to storm. That was to destroy the most elite team of desolate beasts that were attacking the gates of the Steel Keep.

This is a "meat grinding" battle, Xia Weining did not expect that he could see the sunshine of tomorrow, he only hoped that the 30,000 mecha troops behind him, the elite mecha troops who had followed him for more than 20 years, could have someone alive to tell future generations about today's feats.

"The Folding Wings squad obeys the order, follow me! Fight the enemy! ”

At the main gate of the steel castle, 20,000 strong mecha troops were directly thrown into the frontal battlefield, and the desolate beasts that frantically poured up the city wall around them did not pay attention to this small part of the human troops, and still used the corpses of the desolate beasts to pile up the height, desperately jumping up to the city wall.

The Folded Wing Squad led by Xia Weining is currently being eyed by the 100,000 Elite Desolate Beast Legion composed of "Golden-winged Mantis", "Star Bull" and "Horned Spider". This elite team of desolate beasts, which was personally controlled by the starry sky beast "One-horned Heavenly Bull", stopped the siege operation when the human forcible mecha legion appeared in this deliberately left open war area, and began the rhythm of all-out strangulation of the human mecha legion.
