Aliens that can carry out cross-planetary invasions, although their invasion methods are a little low, but they really invade across the "cosmic sea", and they will inevitably have their own social systems, with a rigorous military system and a perfect degree of organization.

After the end of the first great advent, the human beings on the earth discovered that the invading aliens used only a small part of their own civilization to use war methods, and many "big killing weapons" may not have been released in time or were subject to any constraints, and they were defeated without use...... Or rather, the Great Advent is over.

If Lin Bin can live to the later stage of the great changes on the earth, he will find that things are not so simple at all.

The so-called "Great Advent" aliens are real beings somewhere in the universe on the same plane, or they are invaded by an alien plane.

Those "small advents" are a low-intensity "transdimensional" behavior.

I don't know what kind of existence is in the next big game of chess, or some kind of game. Lin Bin didn't have time to think about these things, he was now hiding from the search in embarrassment.

"Damn, we're just looking for death!" Cohens cursed in a low voice: "There are enemy troops everywhere, they have gone crazy!" ”

In the pitch darkness, everyone was huddled in a house, and outside there was the constant sound of gunfire.

On the premise that the aliens did not find the "mouse", they covered the location where they suspected that there were humans hiding, and the green shade that could hide from people was swept by scorching projectiles, and the conspicuous buildings were covered by various types of self-propelled guns, and it was not long before the aerial vehicles also joined in the exploration and carried out abusive bombing.

They had scurried into a tunnel, ducked into a car shelter, and there was just in the tool room where everyone could catch their breath.

It was Lin Bin's deliberate guidance to enter the tunnel, he knew what would happen next, and the tunnel avoidance hole might not be enough for them to survive.

It's not just this area where there's a big movement, Cohens says that the aliens are crazy, and he is referring to the fact that the aliens in other areas are going crazy to attack.

The defense zone temporarily built by the US military was originally just aliens who were attacking step by step, and their command center issued an alarm of infiltration, and immediately changed the previous "tepid" and entered mad dog mode in an instant, not only putting in more aircraft, but also increasing the number of ground troops again and again.

Some alien weapons that have not appeared before, such as a shotgun that can cause a large area that looks like it has been washed by white phosphorus bombs, and an unknown weapon that seems to be a grid in the air, all kinds of weapons that can be imagined or imagined, have been used by aliens on the battlefield.

The U.S. command, which had thought it would be able to hold off at least a week, kept receiving reports of where the defenses had been penetrated, where the troops had been eliminated in formation, where the garrisons had fled, and so on.

Not only has the situation in Los Angeles changed abruptly, but the situation on the entire West Coast is developing in a direction that is unfavorable to the US military, and even not only in the United States, but also in neighboring Mexico.

After the alien invasion, countries with coastlines around the world have been invaded to varying degrees, and the difference is the number of alien troops.

Mexico is also a country with a long coastline, but they are a country that lags far behind the United States in terms of economic and military power, losing its coastline on the first day of invasion and all the states on the Pacific coast in a day and night.

Originally, Mexico noticed that the alien invasion force was in a period of weakness, thinking that it could build a defensive circle of the capital, but what I didn't expect was that the so-called weakness of the aliens before was an illusion, and they were preparing for a more frantic offensive at midnight, and the war burned to Mexico City in less than three hours.

Everyone who was hiding in the tunnel and car shelter, except for Lin Bin, who was reborn, didn't know that the situation had reached a critical moment for the human race on the earth.

Even Lin Bin didn't know that if the alien command centers in various places were not destroyed, the situation faced by mankind would get worse and worse, and it might evolve into a war mode of flesh and blood and intelligent weapons.

After all, aliens have shown intelligence in aerial vehicles, and who can be sure that other vehicles are not intelligent?

Due to the sudden frenzied attack of the aliens, the improvised defensive chain is in danger of being broken at any time, and Washington's side has already put the use of mushroom bombs into the discussion process, and once the situation deteriorates to the point where it is difficult to manage, Washington will use mushroom bombs.

However, mushroom bombs have already been used by some countries, which were once the world's first power, and now they are reduced to second-rate "The sun never sets" despite being one of the five hooligans. They are an island country, which can be used as a landing point for aliens everywhere, there is no depth, there are breaches everywhere, and in the face of the result that will be completely destroyed, they brazenly use mushroom bombs.

Most of them are unaware of what is happening outside the world. Everyone listened to the movement outside, felt the ground tremble from time to time, and their faces became paler and paler.

The ground will tremble must be the relationship between the firepower and the power of the fire, and by this time, even the dull ones will understand, and their infiltration behavior has stabbed the hornet's nest.

"I don't want to say ......," Martinaz pulled an ugly smile, "but we're really going to be heroes." ”

This is the so-called American humor, understanding that it is difficult to live this time, and imagine the bright side.

Nanz looked quite calm, and asked Steven, who was carrying the liaison crew on his back, "Can you contact the outside world?" ”

"I tried it on the helicopter, and I can communicate with the outside world." Steven's face was pale, and his mouth was shaking when he spoke: "We are in the tunnel now, and we need to go out if we want to get in touch." ”

Everyone fell silent.

I don't know how long it took, maybe an hour, or more, but an unprecedented shaking suddenly happened.

Lin Bin, who climbed on the ground, knew that the moment had come!

The storage shelves in the tool room shook in the shock, and everyone fell to the ground uncontrollably, and cracks in the ceiling could be seen under the light of the tactical flashlight.

Outside, a light almost as bright as the sun burst out, and the air between heaven and earth seemed to be sucked by something, and an exaggerated wave of air swept up the moment it lost its light.

Viewed from high above or from a distance, a mushroom cloud rises in downtown Los Angeles, and its appearance only shows the fact that the U.S. military has used mushroom shells on its homeland.

The improvised defensive line collapsed within half an hour, and once the alien forces could rush directly into the interior and rampage, the absolute hawks advocated the use of mushroom bombs, and the authorities, realizing that the situation was irreparable, had no choice but to accept the hawks' opinion directly.

Los Angeles was the first to serve, New York was the second, followed by Washington, Houston, and ...... In a short period of two hours, the authorities dropped a total of 23 mushroom bombs using ballistic missiles or bombers.

After the tremor stopped, the rest of the people in the tool room except for Lin Bin didn't think in the direction of the authorities' use of mushroom bombs, they only thought that the aliens used some exaggerated weapons to cause such a violent earthquake just now.

"I can't stay any longer." Nanz used a tactical flashlight to shine on the rifts everywhere: "This place could collapse at any moment!" ”

The situation is really bad, the ceiling overhead, some of the cement has already shown signs of falling off, and it is really possible to collapse at any time.

The group of people mustered up the courage to get out of the car avoidance, and when they came outside, they noticed a big abnormality, and they couldn't observe more without enough light, and could only smell that the air was full of a burnt smell.

"It wasn't that messy just now." Lark patted the car that had been lifted up and stacked on top of each other, "I remember there wasn't such a thing. ”

Under the lighting of the tactical flashlight, the cars in the tunnel were basically lifted to pieces, and obvious landslides were also found, but fortunately there was no blockage, so that everyone could get out of the tunnel.

When they went outside, they saw that the sky had gradually brightened, the sky was obviously cloudless, but the sky was gray.

The impression of those dense houses is gone, as if they have been subjected to exaggerated and excessive air waves, and there are ruins everywhere, and the trees have been uprooted, and they look full of devastation.

"This is ......" Martinaz was completely incredulous: "Did you use a nuclear bomb?" ”

Almost as if to make a footnote to Martinaz, far ahead of their position, a circular wave of light flashed through the sky, and it didn't take long for the ground to tremble, and then a mushroom cloud was seen in the distance.

"The aliens on the ground can't hold up the nuclear bomb just now." Lin Bin was not surprised by this, there was indeed such a thing in his memory, on the third or fourth day of the alien invasion, human beings used their most powerful weapons. He felt that he shouldn't be so stunned, and puffed up: "We should find the enemy's command center now and finish off the enemy's command hub!" ”

As if he had discovered something, Sandos raised his hand to the right about five hundred meters away and said, "Look, what is that!" ”

The group went in the direction they were pointing, and there was a very noticeable rise there, and a machine full of metal was partially exposed, and it didn't look like it was made of earth.
