Evolution over time and space

The three forces are fighting on their own in the city, cleaning up the scattered Zerg that come to explore the surrounding areas.

Relatively speaking, Chu Feng and the Guards came from a military alliance and had a certain tacit understanding, but a group of Space Marines had no tacit understanding at all. Moreover, not every Space Marine had a sense of justice, and there was never a shortage of troublemaking bastards.

As long as such bastards caused trouble in the area where Chu Feng was responsible for garrisoning, he would issue orders to kill them with military discipline. Of course, this initially aroused the anger of the comrades of the slain, but Chu Feng killed them again.

When the few people who were the most vicious were attacked, the world suddenly became quiet.

In extraordinary times, killing a few bastards will immediately serve as a warning to the monkeys and stabilize the uneasy mood of a group of new recruits. Why not do it!

The area that Chu Feng was responsible for stabilized and he began to order the people here to build a defense base. The people here were not ordinary people on the home planet, 90% were engineers of various types. Otherwise, how could such a steel fortress be produced?

As for materials, there is no shortage of them. There are reserves of strategic resources underground in every city, and the city is part of the Steel Fortress, which is naturally connected to the core machinery of the fortress. As long as engineers add defensive equipment or attack equipment, it can be used immediately.

The city began to consolidate multiple defenses. Layers of heavy steel iron plates, as heavy as mountains, were built around the city neatly and tightly like building blocks under the control of hundreds of mechanical tentacles.

After one hour of construction, a metal wall of more than 100 meters was formed around the city, initially the size of a small metal fortress.

While the city was in a safe period, Chu Feng seized the time to recover the strength he had consumed in the previous battle with Qin Leilong.

Not long after an hour passed, a huge "buzzing" sound suddenly came from the sky, covering it from afar, creating an extremely dense noise, as if something was flying over at high speed.

"Attention everyone! The Zerg Air Force! Will attack in five minutes!"

"Attention everyone! The Zerg Air Force! Will attack in five minutes!"

Announcements from the guards continued to sound in every corner of the city. At the same time, a group of engineers suspended the construction of defenses and activated defense equipment and armed equipment throughout the city. The logistics engineers who were originally in charge became a backup force.

The Iron Fortress is their home, and of course they will do whatever it takes to protect this foundation. They are not like wandering interstellar warriors. Faced with such an alien invasion, none of them flinched and tried their best to exert their due strength.

.

In fact, in every military planet of the Human Alliance, the people have a strong and strong will. Firstly, this is due to the influence of the general environment. Secondly, the people are attached to the planet. Thirdly, not everyone can live on the military planet.

.

If they can live here, they are equivalent to the elites of ordinary people. They are outstanding and have their own pride, such as physical fitness, wisdom, spirituality, etc., which are far superior to humans on ordinary planets."

To put it simply, military planets are first-tier cities, other planets are second-tier and third-tier cities, and the home planet is considered a rural place.

With the help of engineers from all over the city, the city immediately turned into a fortress with iron walls.

Chu Feng finished his body recovery and immediately came to the area where the troops were stationed. He climbed up to the highest steel wall and looked around. He immediately saw a large area densely packed and dark, like the endless night, covering

The sky blocks out the sun, and just seeing such an astonishing number of Zergs makes people's hair stand on end, and they can't even think of defeating them.

This swarm of flying insects covering the sky and the sun is like locusts. Their upper and lower jaws are as hard as metal and have extremely strong chewing teeth. Their saliva can decompose energy and chew through any material.

Suddenly, the huge and dense insect army divided into five groups and flew in different directions.

"They're not exactly coming for us."

Chu Feng guessed that these five flying insect armies may go to surrounding cities. Once a city is breached, the insect armies will gather together and continue to break through the next city.

First, disperse the attack, and then integrate it to break through the city with the strongest defenses.

It is estimated that the flying insect army is just an advance force, responsible for breaking through the city's defenses. The real battle is likely to be fought by war insects on land. And with such an army of insect beings attacking, it is certain that there are intellectual insects.

Chu Feng thought of this and ordered a preemptive strike. He did not hesitate to waste energy and gave up the steady and continuous output. He concentrated the firepower of the entire area at once and carried out a covering explosion. With the strongest firepower, he blasted away the black flying in the sky.

insect!

Only by defeating the flying insects and scattering them can we have enough energy to deal with the attack of the war insects from behind!

After receiving the order, a thousand subordinates immediately executed it.

In Chu Feng's area, the first and most powerful enriched main gun was fired, and then each building turned into a mechanical turret. Countless blazing beams of light pierced the air, blooming into a dense brilliance like a heavy rain.

There were continuous fierce explosions, which seemed to form a crack tearing through the sky!

A large number of flying insects fell down one by one like burnt dumplings, but the next moment, the flying insects spread out into a fan shape, spewing out a stream of green corrosive acid mist, rolling and rolling, forming layers of corrosion protection films, attacking

The energy beams of the past have greatly reduced their lethality.

"Switch to physical bombs!"

Chu Feng did not go to fight, but stood at the forefront and gave orders.

Physical bombs are non-energy beams, which are various types of warheads, such as reinforced alloy warheads, crystal warheads, mechanical warheads, etc., which are substances specially used to destroy energy and restrain energy.

Boom! Boom! Boom!——

There was a loud vibration of metal cracking, as if it had penetrated layers of space and directly hit the green acid mist in the sky. Suddenly, the warhead ejected a large number of broken steel balls, which immediately penetrated the corrosive layer of the acid mist from the inside.

There was a scream, and warheads were fired one after another. Large areas of frozen cold air condensed with corrosive acid mist, turning into dark green hailstones that fell down.

"Switch energy attack."

Chu Feng gave orders coldly, and every command played a key role.

After several waves of physical bomb blasts, the acid mist in the sky quickly weakened. However, the physical bomb's killing range is limited and it is impossible to annihilate a large number of flying insects on a large scale at once. Even with such a low killing effect, flying insects can directly

Killed in front of him.

Even if all the ammunition is used up, it will be difficult to kill three-tenths of the number of flying insects, and the warheads require loading time, making it difficult to attack for a long time. Therefore, physical bombs only play a role in destroying flying insects. To truly kill flying insects on a large scale, it is still necessary to

Relies on energy to attack.

At this time, Chu Feng switched to energy attack, taking into account various circumstances, and continued the offensive in a tight situation to maximize the destruction and annihilate the formation and number of flying insects.

After switching attacks back and forth several times, the flying insects attacking in this direction were all beaten to pieces by the artillery fire, and were completely defeated. However, Chu Feng's energy in this area was almost exhausted, and it would take some time to buffer it.

"Groups one, two, and three, drive mechas to the front lines and defeat them one by one."

"Groups of four, five, and six, fly fighter planes, constantly break up the formation of flying insects, and don't let the flying insects get together."

"Groups 7 and 89, driving heavy combat vehicles and tanks, fully armed and stationed on the defensive frontier, ready to serve at any time."

"Ten groups, release all the robots on the battleship to provide remote output on the ground."

Chu Feng issued orders one after another in an orderly manner. The teams who received the orders took their positions and executed them quickly.

He did not leave any extra troops in the area where he was stationed, but that does not mean that there is no counterattack force here. Don’t forget whose city this city belongs to. This is the home of a group of tough engineers or space warriors. The series of attacks just now were just Chu

Feng Fang's offensive.

Chu Feng and the others are fighting on the front line, while the engineers and space warriors are defending in the rear. Simply put, there are two defense lines. If the defense line stationed by Chu Feng is about to collapse, the engineers and space warriors will immediately provide support.

Everyone has different ideas. Chu Feng believes that wiping out the Zerg as soon as possible is the right way to go, but the people in this city believe that they can better counterattack the Zerg by occupying a favorable position.

Indeed, on the second line of defense, there is a large mechanical formation of engineers, and the Zerg will have to pay at least a lot of money to break through it.

But the number and weirdness of the Zerg must be much stronger than that of humans.

Once it is broken through, the Zerg will be able to march straight in. At that time, the city will be breached.

Soon after, groups of new recruits entered into a battle in the sky, and flying insects kept falling down.

The individual flying insects are not very big, only about the size of a bull's head, and do not have very strong offensive means. A mecha is more than ten meters tall, and it can kill at least a dozen flying insects with one slash. As long as the flying insects form

If you can't form a formation, you can kill them at will.

In fact, flying insects are just a group of soldiers used to break through defenses. They must rely on groups to show their terrifying power. If they are scattered, they will not be able to face the impact of human technology.

The battle in the sky became intense, and battles in other areas also started. However, other areas were not as relaxed as Chu Feng's area. They did not break up the formation of flying insects at the beginning, which resulted in a large number of flying insects forming a corroded area.

Acid mist not only corrodes defensive buildings, but also corrodes human armors, machines, and mechas, making it difficult to unleash their proper power.

Chu Feng did not join the battle. He swallowed nutrient solution or life gene solution one after another. While recovering his strength and adjusting his condition, he was waiting for the next wave of real invasion by the Zerg.

When the second wave of energy was about to be filled, a large number of war bugs appeared in the distance. There were more than one kind of cannon fodder-level war bugs, there were also general-level war bugs, as well as giant war bugs as big as battleships, and they were released remotely.

Warworms of corrosive energy.

The military deployment is exactly the same as that of the regular human army. If this was not a military planet, but just an ordinary planet, there would be absolutely no city that could withstand the impact of a wave of war bugs.

"Everyone gives up the battle in the sky and defeats the army of war bugs on the ground."

Chu Feng stopped swallowing the nutritional liquid and regained 30% of his strength. He was armed with a modified armor. He teleported to the tank and said: "The melee robot turned on the charge mode, and all the heavy tanks formed a triangle battle.

The formation disperses the Zerg army on the opposite side, and the battleship's main gun is aimed at the giant war bug - attack!"

At the command, the heavy combat vehicle tank roared like thunder and exploded at a furious speed. At the same time, each robot was covered with layers of solid energy armor, like a sharp drill, and launched a fierce attack

charge!
