Exchanging the minimum casualties for victory in the war is the basic principle of leading troops to fight, and Luo Jiutian also follows this principle.

The heroes of Bailai killed in the front, and the soldiers finished in the back, dealing with the omissions, which was also the best way Luo Jiutian could think of.

Aliens make good use of laser guns and laser swords, but, with the progress of science and technology, laser guns and laser swords are no longer the dominant battlefield, because, scientists have already studied the defense equipment of laser guns and laser swords, and they are inductive defense equipment, soldiers only need to wear the laser sensor protector developed and distributed by the official, when the high-speed laser beam is 5 meters away from the sensor, the transparent shield will be activated in time, and when the laser is shot on the protective cover, it is like being absorbed by the protective shield, and it will not cause any harm to man. In front of the protective shield, the laser sword is also so fragile. If there is a common laser induction protector within five meters, the guards will resonate with each other to form a continuous protective cover, and the protection distance and protection effect will increase hundreds or thousands of times. Therefore, the laser sensor protector has become one of the indispensable equipment for soldiers on the battlefield of alien invasion.

It's just that the weapons of the aliens will also keep pace with the times, continue to innovate, and on the battlefield, they must prepare for the worst, and the big heads of the aliens will make them far beyond the earth in the scientific research industry.

"Data warfare" and "cyber warfare" hundreds of years ago...... did not let the aliens taste the sweetness, the wisdom and tenacity of the earthlings far exceeded the aliens' estimates, and they did not capture the earth for hundreds of years, so they realized that they still had to fight to the flesh and have a chance to take the earth with real guns.

On the battlefield, the figure of fully intelligent robots is extremely rare, and occasionally they will be used for special tasks, and they will not be used as the main force, because, in the alien invasion station, the robot is expensive, and its attack power is like a meat wall, a meat shield, it seems vulnerable, many times the robot will be used to make a human bomb, a robot that will run to the target to complete the blasting work, will make the enemy have a headache, such a use is still a more worry-free thing.

More than 5,000 people, after a long journey, came to the rear of the alien invaders, lurked, and tried the plane.

According to the military deployment, the front engaged for half an hour, and when it entered a state of fierce battle, Luo Jiutian's rear assault army moved again.

Now, Luo Jiutian's rear assault army is followed by the alien invading army, and the alien invading army is overwhelming, with a large number of people and countless numbers. The high-powered telescope pulls the alien into front of his eyes, and his appearance is not visible, all of them are fully armed, with a pair of strange eyes revealed by the transparent glass cover, walking upright, much larger than a human, and holding a gun in his right hand. However, it was obvious that Luo Jiutian saw several soldiers of different sizes, this was the Alien Alliance Army, which intended to carve up the Earth after occupying the Earth and turning it into the aliens' own "Peach Blossom Spring" and "Resort". Different body types, Luo Jiutian guessed, there must be alien aliens, alien aliens have their own special abilities, compared to other aliens, it is more difficult to deal with.

Looking at their equipment, it is estimated that their arms or other parts are also equipped with weapons such as shooting weapons or grenades, although they are far away, but the mechanical sound of the alien invasion army marching is very loud, it sounds a little heavy, and the ground is shaken by their footsteps, which makes people feel uneasy.

There are fighters flying above the alien invading army, the fighters have been updated, the appearance is similar to a rugby, this is a fighter with no dead ends, a 360-degree field of vision, at least six people need to be overtaken at the same time, powerful, fierce, and the defense is also quite strong, known as the killer weapon on the alien battlefield, but the number is not much, only a handful, but they feel that it is enough.

In addition to the warplane, which is a spaceship, the spaceship is an airborne mobile supply station for the alien battlefield, which is shaped like a large villa to support various medical emergencies, ammunition reinforcements, etc.

The perfect coordination of land and air, coupled with the advanced equipment and weapons, and the advantage of alien physique, their momentum was extremely high, and a confidence of victory came to their faces, and before the war started, they already felt as if they were celebrating.

About two hours later, the battle at the front officially began. Half an hour passed, and the war reached its climax. On the battlefield, friends and foes collide like a flood and a mudslide. Artillery fire broke out everywhere, corpses flew everywhere, blood flowed like rivers, and "human life is as cheap as attacking the wall", this is war.

When the time comes, the timing is just right. Half of the army led by Luo Jiutian attacked the ground and half attacked the air, like a sharp arrow, suddenly plunged into the backbone of the alien invaders, catching them off guard, with a strong enemy in front and an ambush in the back, so that the alien invasion army, which had an overwhelming advantage, was weakened at once.

The aliens also made defensive arrangements in the rear, but the offensive in the rear was far beyond their imagination.

More than 100 heroes, plus 5,000 elite soldiers, took them by surprise and attacked from the rear, this posture was really "cutting leeks", and they didn't have time to cry when they cried.

However, the alien invaders are not vegetarians, and with their huge advantage, after learning that the rear was attacked, all the soldiers in the second half of the troops reversed the defense and attacked in unison, turning the tide of the battle. By this time, their strength had been halved, and the casualties were quite heavy.

And the human army, bluffing in front, fighting but not attacking closely, and silent in the rear, "cutting leeks" in big waves, the heroes showed their outstanding combat strength on the battlefield.

The battle suddenly turned into a stalemate, but after a while, the alien aerial "killer feature" emerged and swept across the battlefield.

For a time, this "rugby" in the air brought not peace, but cruel death and mourning, with strong firepower, but unable to attack, like a burning torch, walking through the forest covered with dead grass, burning wantonly, but everyone did not take him.

This kind of brutal massacre, Luo Jiutian is the first time in his life.

The cannon roared, and the ears seemed to block all the sounds of the outside world, a strong soldier, was blown away, and just fell in front of Luo Jiutian, his left hand was gone, the whole person's flesh and blood were blurred, he couldn't distinguish the mouth and nose, and his right hand was bleeding blood, he used his bloody index finger to write a "twenty" on the ground with the last consciousness, the word was not finished, the index finger stayed on the last stroke forever, and slowly, the blood scribbled on the ground.

This "twenty" written in blood is the honor he exchanged for his life, and no one can erase it, although he didn't say anything, but Luo Jiutian clearly knew that this was the number of people he had killed the alien invaders.

Twenty people, he is no longer an ordinary warrior, he is already a hero of the people, and he has defended the dignity of the people of the earth with his small life. In this battle, there are countless soldiers like him who will die on the battlefield, but everyone dies willingly and deservedly, and everyone will leave their own honor number, which is indelible in the annals of human history.
