Behind the moat are various steel fortresses of different heights and strange shapes.

The predecessors of these steel fortresses, either schools, commercial housing, or private villas, are now enclosed by several layers of homogeneous steel plates.

There are countless mechanical cannons that stick out from the windows, and the walls near the moat, and the walls below three floors are all strengthened with steel plates to ensure that they can withstand the attack of the fourth-level awakened person without breaking the walls. The stairs of each fortress are shoveled up a large amount of soil and blocked directly with forklifts.

The structural shapes of these fortresses were very similar when the 77th Division was in Changtai. Due to the sufficient time, the structural strength of these buildings was greatly strengthened.

The roof of each building is covered with gunman fire points. In addition to the fortress, several trenches were also dug on the other side of the road, and countless soldiers were running around in the trenches, mortars, machine guns, rocket launchers and other light weapons were already everywhere.

In order to prevent the "air raids" of the birdmen, these trenches temporarily dug out on the ground have also been prepared to avoid the source air defense cat ear piercing. The birdmen above level 4 released big moves like "Meteor Fire Rain". Although it would burn with scary power, it was actually very easy to deal with them with guarded ground positions. As long as they did not touch these guys who were as annoying as napalm bombs, the kill range and area of ​​the killing, the source fireballs of the level 4 birdmen were even worse than conventional napalm bombs.

Lin Feng's former unit, the 77th Division, has long been dismantled and reorganized. As a unit that has been fighting with awakened people for a long time, participated in the Great Grass mowing operation and has rich combat experience. The veterans in this unit were dismantled and dispersed in the newly formed three new recruit divisions in a way that one old leads three new ones.

As noon approached, the dark tide finally approached Tianhe City.

The first one that appeared above the city was still dense birdmen, with a total of 500 heads, including eighty level four birdmen, and two of the level five birdmen.

In the Tianhe defense circle, with a command, the group of anti-aircraft artillery arranged behind began to fire.

A loud noise was heard, and a group of 150 groups of anti-aircraft guns of about 85 to 100 mm were firing at the group of birds.

These artillery are old objects from the 1960s and 1970s. With the development of the times, they have long been eliminated and retired to the third line or even directly entered the warehouse to be sealed. However, in this era of crisis, the weapons that most soldiers, who were of age and even at the scene, were pulled out again.

China is actually a country with huge weapons stockpiles.

After the crisis of Awakening, countries were caught off guard. Many countries that have been peaceful for too long cannot provide enough weapons between Wupu, but for China, this is not a problem at all.

In the first thirty years of the era of the first leader, due to China's harsh international strategic environment and preparations for the "World War III", China produced a large number of weapons in the first thirty years, such as 30 million 56 and semi-automatic rifles, and many grenades that were claimed to have used not only after the World War III.

Tianhe is located in the three northeastern provinces, with "Soviet Revisit" in the north, with the US imperialists in the east, and close to the capital. The combat readiness here is the best. All weapons and ammunition are sufficient. After the crisis broke out, the official transformed production at the fastest speed. Before abandoning Huanghua City, he even used the equipment there to produce a large number of ammunition.

The Black Tide Crisis is actually only less than a month. After one month, the military can only survive this crisis, and the military can easily recover the lost land that they gave up.

The shells kept exploding in the air, and the sky and the earth were filled with the roar of Thunder God. Some new recruits instinctively covered their ears in the loud noises.

All of them are less than level 4, and they are all ants.

In the face of the steel storm cast by human technology, the third-level birdman mixed in the middle of Level 4 was quickly eliminated. The flight speed was a little slower than the World War II spiral plane, and under the anti-aircraft artillery fire and attacks that had been prepared on the ground, it quickly became like a shot down wild duck fell head-on from the air.

The remaining fourth-level birders relied on the power to protect the city, but they were greeted by fierce shootings from various small-caliber rapid-fire guns from twenty millimeters, thirty millimeters, including a large number of 12.7 millimeter anti-aircraft machine gun bullets.

Although both of them are level 4, the source strength of the birdman is half worse than that of the land-type awakened man. The entire battle process was without any danger. The birdman's attack on Tianhe's defense line was only caused by some fires and freezing on the ground. A small amount of "sputtering" damage touched some unlucky soldiers and caused trace casualties, but he suffered heavy losses under the dense firepower of humans on the ground.

Among the bird crowd, the strongest level 5 birdman with key protection capabilities was even set up at a high place when flying above the city. Cao Xinxin controlled the superconducting electromagnetic cannon and fired two bombs in succession, directly killing it in seconds.

When the Birdman attacked, Lin Feng, who was on the front line, had nothing to do. In order for him to maintain a better combat state, Ouyang did not ask him to take action, but just ordered him to rest and standby.

In the half-awakened army, Chen Ming, who was watching this scene, smiled at his friend Xie Yi and complained: "Xiao Xie, do you know what I think now?"

"What do you think?"

Chen Ming, a half-man, waved his hand boredly and said, "I remembered the movie I watched before, "The Stars Team". When I watched this movie, I thought it was very good. Now, I think it is a very stupid movie."

Xie Yi touched the tiger beard that had just grown from the corner of his mouth and smiled and said, "I know what you want to say. You want to say why humans in the movie are so stupid that they can't drive tanks or cannons, so they just use rifles to fight with insects."

Lin Feng, who was standing beside him, heard their conversation and interrupted: "If you go to the real world, don't shoot all the movies of killing bugs, killing monsters, and killing zombies."

The new ideological instructor Shen Yan also smiled and interrupted, "So, that's a science fiction movie. If you think of a story, the story can't be made up."

Chen Ming complained easily: "Before the disaster, I used to like to read the end-of-day novels at Qidian. Now it seems that most of the authors of the end-of-day novels are opening up the aura of mental retardation. By reducing the IQ of human beings, we can compile the story of the end-of-day stories. Thank God, we live in a real world, where there is no an aura of mental retardation for all human beings, and these monsters are stupid enough."

When he said this, Chen Ming seemed to notice that he was also half-human and half-beast, and had already entered the range of monsters. He snorted and then snuggled.

When I was in Changtai Town, the 77th Division, which was several times weaker than Tianhe's air defense force, could easily defeat the bird crowd, not to mention Tianhe City, which has a huge killer such as superconducting electromagnetics. The bird crowd's attack on Tianhe failed without any suspense.

Lin Feng interrupted Chen Ming's "feeling good" on the side and reminded him: "The key to this battle is not now, but after repelling this wave of black tide, can we kill him to silence him before the retreating octopus man meets with the new octopus man."

Unlike awakened people who only have ignorant consciousness, octopus people are intellectual and they can also learn.

Through his own experience, Octopus Lin told Lin Feng that the way octopus people learn is called experience superposition.

When the octopus man of the leader of the Kuroshima meets fire, the winner can not only get all the opponent's subordinates, but also get all the opponent's experience through the spiritual conflict between the two sides.

After absorbing the experience of one party, the octopus that survives will greatly improve its intelligence in a short period of time.

It is always easy for humans to resist the impact of the black tide at the beginning, but the more difficult it is. Not only will the more advanced awakened people in the black tide over time, but waves of dark tides will come. After their leaders are in a fire and conflict, the octopus people will gather their respective combat experiences, leading to the increase of the brain's intelligence. Not only that, the closer the octopus people are to death, the more obvious their wisdom will be improved. Information from various countries shows that the same signs have appeared in those human cities that have been compromised: the first wave of black tide attacks, the tactics of awakened people under the control of the octopus people are extremely stupid.

But when two waves of octopus people meet and the fire breaks out, and the second and third waves of the black tide attacks, they obviously know how to use tactics.

If humans can survive until the fourth or fifth wave, they will face more variable and targeted attacks from their opponents.

How to deal with the Black Tide crisis? Octopus Lin’s advice to Lin Feng is to launch a pursuit operation immediately when repelling the Black Tide. Don’t let the octopus man with combat experience escape. Kill him before he and the new octopus man get together, and don’t give them time to pass on experience and learn lessons to grow.

The reason why Ouyang Hua has great confidence in defending Tianhe City is because the information obtained from satellite surveillance ground shows that he only needs to resist three more waves of black tide impact here.

Before today, four waves of the Black Tide crisis had actually been resolved.

The first wave of black tide was led by the Octopus Forest before it was contaminated by Lin Feng. At that time, he was repelled by the military outside Changtai Town.

Then, the leader of the Black Tide, Octopus Man, met the Second Black Tide near Changtai. When the two octopus men were in a row, Lin Feng intervened and turned the octopus man of the First Black Tide into another "self", which is "Octopus Lin Feng".

Then this octopus forest, which "only loves himself", set up traps one after another, killing two octopus men, and invisibly helped Tianhe resolve the impact of the other two waves of black tides.

Tianhe City, which had to bear the impact of the entire seven waves of black waves, was because of Lin Feng's "intentional" mental contact pollution outside Changtai Town, and it became a matter of responding to the remaining three waves of shocks, and the "difficulty of clearing" suddenly dropped by more than half.
