Because people in the three cities all know that once the sky city falls down, the insects will not let go of any human beings, even the infants in their infancy will become the food for the insects.

At this moment, the fierce battle of defending the city of the sky has begun, accompanied by dense bullets and shells.

Countless fighters and armored flying vehicles are pouring out in front of the terrifying insect sea. Thousands of mecha fighters are busy among various large-scale machines, just in order to be able to shoot more and kill more hateful insects before the insect sea comes.

Fortunately, the three cities of the sky, which participated in the battle of defending the city of sky, even though they lost a lot of money under the ground in order to arouse the anger of the mother insects, they still had quite terrible fighting capacity.

Relying on the city of the sky, countless large and small gun barrels began to roar wildly, and countless soldiers stepped into the trenches to shoot at the insects.

At this moment, the sky and the earth look pale in the face of the war between the two races, the personal strength appears so powerless in the face of the confrontation between the two armies, and life is so fragile in the crazy killing.

Both insects and human beings are burning their lives in the fire of war, just to make the balance of victory incline to their side.

The cruel killing has been going on. It seems that there is a flesh and blood mill between heaven and earth. Human beings and insects put their own kind into it. When the "mill" starts, a broken corpse comes out again.

Three thousand meters below the ground, Li Xingyun and Alva buried their own in the soil without breath, and countless insects dug tunnels along their side to the ground.

For the four of Li Xingyun, who were close to each other, even if they saw the insects, they would be blind as if they were blind, and they crossed directly over.

"The war has begun"

the four people of Li Xingyun felt the continuous vibration in the soil, and immediately knew that the war had broken out. Even if it was 3000 meters below the ground, they could clearly feel the intensity of the war.

"The stratagem of the Terran high level has been successful, but is it worth sacrificing so many soldiers and trampling on the bottom line and dignity of the Terran for the sake of this situation? "

although it is the duty of a soldier to obey orders, it is true that in order to lead the snake out of the cave, it is really right to feed the brave soldier to give the snake in the cave.

Can the pride of the human race and the dignity of the human race be trampled on with no bottom line.

The answer to all this can't be said. They are fearless fighters in the battlefield, but they are also living people with flesh and blood. After being abandoned by their own country, by their own trusted and proud federal government, can they continue to fight fearlessly for the pride of the human race?

"What's next? "

after the three people fell into confusion, they subconsciously looked at Li Xingyun. By this time, almost all the insects on their side had gone out, and no insect could be heard within a hundred miles.

"It's a matter of course. Now it's meaningless to tangle with these things. What we need to consider now is whether to go up to join the army or to set up the destiny of each other"

after thinking about it, Li Xingyun also felt entangled.

The original plan of Li Xingyun and others was to clean up the false nest and follow the Terran army to attack the real nest of the female Zerg, where to continue Li Xingyun's mission.

Li Xingyun estimates that after several successive wars, even if the number of insects to be killed in the hunting list is large, it will be able to complete half of it.

In this way, as long as we participate in three or five times of such group operations, Li Xingyun's task one will be able to complete almost.

With task two already in hand, the remaining task three can be said to be the most relaxed.

After all, it's too maneuverable to participate in the battle of defending the city of sky. If you go to the battlefield and hide after firing a gun, you can say that you are participating. Even if you are just helping to transport logistics materials, you can also participate in it.

Therefore, Li Xingyun's plan is to take part in the wars between Terrans and Zerg under the escort of Alva three people after getting the heart of the female worm, and brush the insect soldiers in a relatively safe situation. In the end, I was looking for a city of sky to defend the city, and then I went back to the black prison college.

But now Li Xingyun's seemingly smooth plan suddenly has a difficult labor.

How strong is the battle intensity of the guardian war of the city of the sky?

The Zerg forces Li Xingyun doesn't know, but he knows the Terran forces.

The number of permanent troops in the pioneer City alone has reached 30 million, and with its residents, 430 million people, this is still the combat power of one of the cities in the sky.

The three cities of the sky add up to more than a billion people participated in the war.

This level of large-scale war, not to mention Li Xingyun, who has just entered the level of Planet 2, even the master of planet 5 and 6 does not dare to fight in front of the battlefield. Even Superman would have to be blasted into slag if he was not careful about the fire of the other army.So this scale of war Li Xingyun is very repellent, on the battlefield is completely fighting for character and luck.

But now the four of Li Xingyun are blocked in the rear of Zerg, so it is necessary to go back to the front battlefield of sky city.

But if they don't go back, where can they go? The whole earth is full of insects.

After thinking about it for half a day, a crazy plan gradually formed in Li Xingyun's mind. Li Xingyun bit her teeth and pointed to Alva Sanren: "suddenly, the agreement with you has been cancelled, and the three don't have to be my guard."

"but now that the war between the human and the insect has broken out, and our way back has been cut off, I'll ask the three, would you like to Fight with me "

" if we win, we will dominate the direction of the war. If we lose, we will be the place where there is no burial place "

after Li Xingyun told us all his plans, Alva and Alva made up their minds.

"For the glory of the human race," Li Xingyun put out a fist among the four.

"For the pride of the Terrans," Alva handed in his second fist.

"For the fearless soul," Yi Han's eyes are like electricity and death is like returning home. He stretches out his fist.

"For the tens of millions of heroes buried in front of me," Marcos sandbag sized fist tightly clenched up.

Four fists of different sizes crossed together in the dark underground. At this moment, in this unknown place, four people from all over the world, in order to protect the faith in their hearts and the last pride of the human race, resolutely set foot on a road that is likely to be a great abyss, a road that may change the course of history.
