The Zerg's vanguard legion is always dominated by the most mobile velocity and flying insects. However, compared with the insect swarms that Zhou Feng had encountered before, the Zergs that marched to the three major federal shelters this time are undoubtedly much more numerous.

Moreover, the so-called vanguard legion is not actually used to deal with the three major fortresses of the Federation, and is used to eradicate the human and mutant forces along the way. The saying that insects are not growing is not in vain. With the rapid advance of the Zerg vanguard legion, some human bases and mutant bases that blocked their marching path were completely destroyed by these insects, and the survivors in the ruins naturally became the marching rations for these insects.

In less than ten days, the Zerg Pioneer Legion crossed most of the Jiguniya Plain and continued to advance towards the three major federal shelters. Among them, the Flame Fortress and the Ice Fortress had already had contact and war with the Zerg, and the swarms heading to the Thunder Fortress were getting closer and closer, and contact was expected to take place in less than ten hours.

The Zerg legion composed of mere velocity and flying insects cannot pose too much threat to the three fortresses, but it will actually consume the energy reserves of the three fortresses. This is also the cannon fodder tactic that the Zerg has always used. Once the energy of the three fortresses cannot maintain the defense field, they will dispatch high-level Zergs to break through the city's defense system in one fell swoop, and enter the city to fight against humans. Judging from the forces sent by the mother nest this time, the three fortresses can hold on for up to six months under the siege of the insect swarm, and then face energy shortages. Moreover, this is just to deal with the Zerg vanguard troops. If the Zerg subsequent army is pressed, the time will be greatly shortened.

However, a few months are enough for Zhou Feng and others to go to their mother nest to kill the Zerg leader, but before that, they must consume the Zerg strength as much as possible. First, the longer they persist, the more troops the Zerg will send, and the strength of the Zerg will become relatively empty. Second, each insect is an opportunity for crystal diamonds and improvement for Zhou Feng and others. They need to use these critical periods to improve their strength as much as possible, thereby increasing the success rate of the beheading plan. Especially Zhou Feng, he is only one line away from breaking through the seventh level. Once he successfully breaks through, his strength will be greatly improved.

As the Zergs continued to approach, the entire Thunder Fortress also announced that it had entered a wartime state. In the wartime state, every federal citizen must hold weapons to defend his home, and all living and daily life must be militarized to prepare for emergencies. However, so many years of war have made all federal citizens accustomed to fighting with insects. In addition, the federal government did not tell the public the fact that this worm tide attack was a general offensive, so the entire Thunder Fortress remained stable when the troops were at the city, and there was no chaos.

Boom boom boom boom boom boom boom!

Time passed quickly in active preparations. Soon, accompanied by violent roars, grey dust rose from the end of the horizon, and then formed a huge gray dragon to sweep towards the Thunder Fortress. At the same time, flying insects also appeared in everyone's field of vision, running wildly like black sea tides at an extremely fast speed.

"Flame the T85 incendiary bomb!"

Looking at the endless tide of insects gradually appearing at the end of the horizon, Kurt Kings' eyes suddenly condensed, and then he picked up the communicator and whispered the order. As his order was issued, hundreds of incendiary bombs also shot out from the missile launch tower of the Thunder Fortress, and with a wisp of flame long tail fell heavily into the distant insect swarm like a flying meteor.

Boom boom boom boom boom boom boom!

Accompanied by the roar caused by missile detonation, the black worm sea in the distance suddenly turned into a sea of ​​fire. Under the burning of high temperature and flames, both the flying insects and the velocity were quickly burned into coke like grasshoppers falling into the stove. Just one volley blocked the progress of the entire volley, and the smart computer that Kurt carried with him also showed the estimated killing of this volley.

A total of 120,000 Zergs died in the burning flames at the first time! And this number is still rising!

"What a terrible power..."

Seeing the information emerging on Kurtna's smart computer, Zhou Feng's eyes suddenly narrowed slightly. Technological weapons are typical weapons that are weak when they encounter strong, and weak when they encounter weak. If these high-temperature incendiary bombs hit him or Ides, they will be difficult to cause damage to them, but after hitting the swarm, they can cause 120,000 damage at one time. This terrifying lethality is probably difficult for some eighth-level strong men to do it at one time.

"Why not attack while the swarm crosses the Jiguniya Plain? Wouldn't that cause more effective damage?"

Looking at the sea of ​​fire burning in the distance, Zhou Feng suddenly frowned. With the lethality of these technological weapons, if the insects attacked the insects just after they left the insect nest, or directly attacked the insect nest, wouldn’t it be possible to kill these insects before they crossed the Jiguniya Plain?

"It is impossible to attack the nest. The nest itself has extremely strong energy and magnetic interference, and our weapons cannot lock it from a long distance."

Hearing Zhou Feng's words, Kurt shook his head helplessly and said, "As for attacking insects, hey, since the nuclear war broke out, our satellites have lost their function and cannot conduct long-range shooting at all, so they can only wait until the Zerg enters the visible range before they can attack them."

Speaking of this, Kurt picked up the communicator again and shouted coldly: "Release the G80 magnetic bomb, and then release the T95 high-temperature incendiary bomb in thirty seconds!"

Swallowing, swishing, swishing!

As Kurt finished speaking, a large number of black missiles shot out from the Thunder Fortress again, and then fell into the swarm of insects in the distance that had already used flesh and blood to extinguish the flames and advance again. However, to Zhou Feng's surprise, these black missiles did not explode after they entered the swarm, but instead radiated a large amount of black mist spreading in the swarm while rotating. As the black mist spread, the speed of the swarm of insects suddenly decreased significantly.

Boom boom boom boom boom boom boom!

Just as the speed of the insect swarm was greatly reduced, thousands of white missiles soared into the sky and sank into the huge insect swarm. Then, flames that were far more hotter than before rushed out in a burst of roars, instantly burning the Zerg within the coverage area into coke, and spreading to the surroundings at an extremely fast speed like a prairie fire.

"The G80 magnetic bomb can release extremely small magnetic traction devices, that is, the black fog you see. With the action of the magnetic traction devices, these Zergs will move more slowly, thereby increasing the lethality of the incendiary bombs."

Looking at the surging sea of ​​fire in the distance, Kurt said indifferently: "The T95 high-temperature incendiary bomb is an upgraded version of the T85 incendiary bomb. It has greater power and lasts longer, but the higher the cost. We cannot use this kind of incendiary bomb indiscriminately, after all, we have to keep the main force of dealing with the Zerg. So it won't take long for these insects to break through the blockade and come to the city. At that time... it's time for the Thunder Defense System to take effect."

"Thunder Defense System?"

Hearing Kurt's words, a flash of light flashed in Zhou Feng's eyes. The Thunder Defense System of Thunder Fortress and the Flame Defense System of Flame Defense System of Flame Defense, and the Ice Defense System of the Ice Defense System have become the three strongest defense systems in the Federation, and the lethality of the Thunder Defense System is the stronger. However, Zhou Feng only heard of it and never saw it with his own eyes. He didn't expect that there would be this opportunity today.

Hissing!

The vast sea of ​​fire lasted for nearly thirty minutes before it was slowly extinguished, and the casualties of the Zerg also reached an astonishing millions. However, compared with the hundreds of millions of Zerg army, these millions were just a drop in the bucket. So soon the black sea of ​​insects quickly spread towards the Thunder Fortress in a burst of hissing sounds again. At the same time, the flying insects in the sky were like a large cloud, covering the Thunder Fortress.
