To be honest, until today, Ling Hai felt as if the alien invasion was not as dangerous as he imagined.

From apprenticeship to internship, to graduation assessment, although there is a crisis in the middle, it is far more than Ling Hai, who once reshaped the strength of the warrior, and feels that the beast soldiers are just like that, he thinks that as long as there is sufficient preparation, the alien beast soldiers seem to be at the mercy of humans at will.

Thousands of beast soldiers killed during the apprenticeship, and the graduation assessment can be easily completed...... All of this gave Ling Hai the illusion that the alien beast soldiers were under the control of humans.

Unconsciously, Ling Hai swelled a little, he felt that the beast soldiers could not pose much of a threat to him, so he dared to go to the combat zone alone to find Liu Song.

But when he really saw the battle of the alien beast soldiers, he suddenly realized that what he had done before could only be regarded as a child's play.

During the period when they grew from rookies to qualified soldiers, the military put in a huge amount of effort, and the pressure of all the cadets was borne by the military at least ninety.

Now, Ling Hai finally understood why humans, who possessed high-end weapons, could only be forced by alien creatures to retreat into the Tyre defensive shield......

At this moment, Ling Hai didn't dare to look up at the outside of the defensive shield for a long time.

Ling Hai is like a small boat staying in the deep sea, and the attacking beast soldiers are like a monstrous wave sweeping in, and after watching it for a long time, the sense of fear will make people crazy and desperate.

How many beast soldiers were attacking, Ling Hai didn't know how many of them, he only knew that on all the defensive covers he could see, there were countless beast soldiers stacked at this moment.

Standing alive on the dead body, the beast tide surged higher and higher, impacting the cover wall!

Fortunately, the walls of the L-shaped shield are 40 meters high, otherwise the beast tide might have poured in. And this is still the result of the army using tanks, cluster missiles, mechs and fighter jets outside.

This beast tide is no longer a simple combination of bursting teeth and unicorns. In the herd of beasts, Ling Hai also saw the [Shield Beast] and the [Bombardier].

[Shield Beast] is a defensive class among the alien beast soldiers, with a height of about 8 meters and a length of about 20 meters. They resemble rhinos on Earth and are stocky. Aside from the difference in size, the biggest difference between the two is that the skin of the shield beast is very hard, and ordinary pistol bullets cannot penetrate the skin of the shield beast at all.

The hardest part of the shield beast is the head shield that can cover eighty percent of its body.

The Shieldbeast's head shield is oval-shaped, and when it raises its head in a defensive stance, the hard head shield can help it block human cannonball attacks.

For non-armor-piercing shells, a minimum of 5 shells are required to completely kill the Shieldbeast, and at least 2 armor-piercing shells are required.

The only purpose of this kind of defense perverted alien beast soldier on the battlefield is to send cannon fodder such as bursting fangs and unicorns to the vicinity of the human defense shield for destruction. On the way to the defensive cover, cannon fodder beasts such as Burst Tooth and Unicorn hid under the belly of the shield beast.

Under the command of the alien commander, when they are still far away from the defensive shield, the shield beasts are separated from the other beasts, and the human cannonballs can only be separated to kill them.

And when the shield beast is close enough to the defense shield, they will be united, at this time, humans must destroy the shield beast as soon as possible, otherwise when the shield beast is really close to the defense shield, there is nothing to do with the shield beast.

You must know that the impact of the cannonball is two-way, and if it is used to attack a shield beast close to the shield shield, it is very likely that the human will destroy the defense shield before killing the shield beast.

As a result, the shield beast, a meaty creature that has no desire to attack, but completely obeys the command, has caused great trouble to humans.

If that time really comes, there will only be one way to solve the shield beast, and that is - mecha!

If the Shield Beast is the second biggest threat to the human defenses, then the first one is undoubtedly the [Bombardier].

In human aesthetics, the bombardier is a completely deformed creature.

They are about 10 meters tall and have arms about 8 meters long, walking upright in humanoid shape, with yellow skin all over their bodies, no nose, no ears, no hair, and a face consisting of a large eye and a large mouth. Just by using his appearance, he can scare crying children.

But deformity is secondary, and the real danger of the [Bombardier] is its terrifying throwing ability.

As the name suggests, the bombardier with an arm length of 8 meters has extremely developed hand muscles, and the objects thrown by it are no different from tank shells just by looking at the impact force. This kind of impact force is extremely damaging to the defensive shield, which will greatly consume the energy of the defensive shield, and what is even more terrifying is that the object thrown by the bombardier is not a simple stone, but an alien creature that acts with it - [Bomb Bug].

The Bomb Bug is a completely suicidal creature, with a grayish-white appearance and the size of an adult shepherd dog. In appearance, the bomb bug is more like a hedgehog, and can curl its body to form a sphere. However, the bomb bugs have no stingers, and the surface of their curled bodies is smooth streamline.

When the bomb worm's body turns spherical and the off-white body turns black, it means that the bomb worm is in a state of self-detonation.

When the Bombardier throws a Bombworm in this state onto the surface of the shield, the Bombworm will explode instantly!

At that time, in addition to the kinetic impact, the bomb bug will also produce an extremely corrosive liquid that will destroy the physical structure of the shield.

That's why bombardiers can be the biggest scourge of threat shields.

Because of this, bombardiers on the battlefield are the first order of orcs that humans need to eliminate.

If it weren't for the relatively small number of bombardiers, humanity's defenses would have been in jeopardy.

What Ling Hai is facing now is a complete corps composed of beast soldiers such as one-horned, bursting fangs, shield beasts, and bombardiers.

Under this beast tide, the individual strength of human beings was so insignificant, and Ling Hai's previous expansion had turned into fear at this moment.

After being recruited by the military, Ling Hai has been working hard, not daring to look at the defensive shield for a long time, just for fear of seeing the beast tide swarming in after the defensive shield that has been attacked suddenly bursts.

He didn't dare to imagine what hellish the tenth district was now after being swept by such a tide of beasts!

Liu Song, is it still possible to be alive......

Fear and powerlessness were intertwined, like an ant gnawing at Ling Hai's heart, and Ling Hai was extremely uncomfortable.

He could only let himself gradually become numb in the labor of carrying, so numb that he had no time to care about anything else.

Time passed in a state of darkness, and the fierce battle between humans and alien beasts continued until nightfall.

It wasn't until around eleven o'clock in the evening that the situation changed.

As the human race invested more and more troops, the losses of the alien beast soldiers rose sharply, and finally one side chose to give in.

In the intercom channel's continuous battle announcement, Ling Hai learned that the beast tide had begun to withdraw troops, the first-level security was downgraded to the third-level security, and the military began rescue work.

Ling Hai, who heard the news, was like a new life. This experience caused a great test to Ling Hai's psychology, and the cruel battlefield made Ling Hai grow up almost overnight and become more mature.

Although Ling Hai, who was in the defensive cover, did not kill a single beast soldier in this battle, the continuous high pressure for several hours was enough to change a person.

In fear, Ling Hai recognized himself, but also became stronger. Most of the fear stems from the unknown, and after Ling Hai has seen the real big battle, he is no longer a rookie who sits in a well and watches the sky.

Just as Ling Hai was about to board the transport plane and return to the Inner Domain, fate played a joke with Ling Hai again.

Military channel: "Now report the list of missing soldiers, please pay attention to the search and rescue of the missing soldiers...... 8 Lian Jibo, Huang Jianxiong, Liu Song......"

Hearing the word "Liu Song", Ling Hai's body instantly froze in place, and he lowered his head and couldn't see his expression.

After a while, Ling Hai slammed his fist into the hard stone, and warm blood flowed from the sunken fist marks......

Ling Hai blamed himself extremely at this moment, because this was the second time he had forgotten to look for Liu Song......
