Ye Feng didn't know how they did it. This completely refreshed his knowledge. It seems that science is not ignored here. The understanding of technology is probably much more advanced than that of the earth. At least this is definitely done on the earth.
Less than.
As soon as he came out of the big tent, all kinds of noises hit his face again. Ye Feng didn't know what method was used in this hall to completely isolate the noise from the outside world. Obviously, this was a technology that he couldn't understand.
Because they had received new combat orders, the density of arrows flying out of the boulders in the sky was obviously higher than before. At this time, shouts of killing were also heard on the city top. It was obvious that the Zerg had already attacked the city.
Sure enough, as soon as we reached the top of the city and looked around, the city was densely packed with insects.
Also affected by the city wall, attacks within the city move in a parabolic motion, and the area nearly a kilometer outside the city wall is also a blind spot for attacks, which is why the trenches were only dug up to this point.
At this moment, the trench has been filled with countless huge roads up to 100 meters wide, and the Zerg are passing through it in an orderly manner.
"Uuuuuuuuuuuuuuuuuu"
At this moment, a low muffled sound suddenly came from behind the Zerg. The sound was very much like the sound of a dharma trumpet, as if it was giving an attack order to the Zerg.
"Squeak, squeak, squeak!"
As if in response to the dharma call, the Zerg below the city let out a loud cry. The cry was so sharp that it hurt people's eardrums.
Following the cry, the secretly numb Zerg under the city took action at the same time.
Some millipede-like insects lay down on the spot, and their one-meter-long legs stood up one after another. Then, like arrows, they fell off one after another and shot into the sky.
After the insect legs flew hundreds of meters high, they all turned around and rained down on the city. Sure enough, this was an attack from the insect tribe.
Ye Feng could clearly see that this attack was a one-time attack. The millipede disappeared after shooting out all its legs. It was probably a suicide attack.
Another ant-like insect on the side quickly inserted its mouthparts into the body of the millipede after it was launched. After just a few breaths, the millipede shriveled up and was obviously dead.
The ant that sucked up the millipede immediately began to deform, and soon turned into the appearance of a millipede. It lay down and launched again. After launching, another ant came forward to suck up the millipede. It repeated over and over again, which was really shocking.
The millipede corpses turned into dry shells were quickly collected and stacked by other insects. After a while, it could be seen that they were building a slope. This was obviously using the corpses to build an attack path.
"Holy shit!"
Seeing this scene, Ye Feng couldn't help but curse.
The Zerg's method of attacking the city is too rogue and basically unsolvable.
They are using their lives to build roads and their corpses as building stones. Even if they are killed, it is just like actively helping them build a road building stone. They are not calling at all.
People rely on their huge ethnic base. If they want to kill you, just kill them. I have more people, so if you die, you can fill holes and build roads.
Isn't it just a 100-meter city wall? The bugs piled it flat with corpses. Once they reached the attack height, the overwhelming bugs would rush up to the top of the city along the slope.
However, after thousands of years of fighting, how could the human race allow them to succeed so easily? They already had countermeasures.
After all, the corpse of the Zerg is not a stone. In any case, it still looks like an organism.
Materials in nature can be transformed into each other. A corpse is still a corpse after all, and a large amount of its volume can be consumed through burning.
Once a millipede measuring more than ten meters is burned, all that will be left is a basin of ashes.
If you want to use this bit of ashes to build a slope that can attack the city head, it will not happen overnight.
Sure enough, when the pile of insect corpses piled up by the Zerg was no more than ten meters high, the city wall guards poured down barrels of oil. Within a moment, a raging fire broke out under the city.
Tens of meters below the city instantly turned into a sea of flames. The fire shot up dozens of meters high. The billowing smoke covered the sky and the sun, and the day almost turned into night.
Countless bugs below the city were engulfed in a sea of fire. Fire bugs rushed randomly one by one, and more bugs were affected and ignited. The scene was extremely chaotic.
The weird cry that the insect made before it died made people's eardrums hurt, and the soldiers at the top of the city covered their ears one after another.
The stench of burning limbs also hit your face, making you nauseous and extremely sad.
The garrison at the top of the city actually had a hard time. Although anti-shooting nets had been deployed at the top of the city and the sergeants held up their shields for defense, those insect-footed arrows were too dense and continuous, and eventually there were weak points that were caught.
They were defeated, so there were many casualties.
Of course, the most troublesome thing is the fireballs fired by the cannonworms.
Those are energy bombs. Although the damage is extremely strong, due to the lack of density of the fireballs, the flying speed is relatively slow. As long as you avoid them in time, you can usually avoid them.
But with these insect-footed arrows, it is very troublesome to cooperate with each other. Energy bombs must be avoided. Once hit, ordinary soldiers have no means to resist, so they are easily hit by insect-footed arrows when dodging.
The Zerg's attack methods are far from being so simple. Some bugs actually have suction cups attached to the city wall and slowly crawl towards the top of the city.
Swarms of large flying insects grabbed the insects one by one and flew over the city, dropping the insects directly.
Fortunately, these insects were not large in size and did not have strong fighting power. Although they caused some chaos to the defenders, they did not cause much damage. Instead, these killed insects became supplies for the defenders.
Ye Feng looked at the chaotic battlefield. Although he felt that the Zerg were indeed crazy, he did not think that such an attack could break through the city defense.
"Brother, do you think the Zerg attack is not that powerful and it is not difficult to defend it?"
Ye Huang saw what Ye Feng meant and asked with a slight smile.
"I feel like it's impossible for them to capture the city."
Ye Feng nodded.
“What you see is just an appearance, it’s not really what it is.
The Zerg relies on a large number of people. Because they are all suicidal attacks, they will not tire, they will always be a fresh force, and their attack power will not decline in any way.
On the contrary, they will devour their own kind and evolve on the battlefield, so as time goes by, their individual combat capabilities will only become stronger and stronger.
The vast majority of our sergeants are ordinary people, and long-term high-intensity combat will only make them weaker and weaker. Even if we arrange battles in turns, it will not work as time goes by. Therefore, as we fight in the later stages, our combat effectiveness will gradually decline.
There is another biggest problem. In the later stages of the game, our trebuchets will gradually lose their effectiveness.
Massive rocks will form a small embankment on the battlefield, and the Zerg on the reverse slope will no longer be harmed, and the attack efficiency will be greatly reduced."
"I see!"
As soon as Ye Huang reminded Ye Feng, he understood that as his long-range lethality decreased, more Zerg would easily reach the city, which would naturally increase the pressure on the city defense forces.
The biggest problem should be fatigue. After months of non-stop fighting day and night, and the rest environment is so bad, physical fitness will inevitably decline.
The Zerg actually don't care about the effectiveness of the battle. They use fatigue and attrition warfare.
