A total of three barriers were set up around Changchun City, each of which was a wall thirty meters high, and soldiers stood on the wall and condescended to strike at the monsters.

The other side is full of bugs, and the trenches not only do not hinder them, but also make their movement easier, but this kind of wall-like structure is more effective against the advance speed of monsters.

In front of the first barrier, the vast army of ants had already rushed over, and the soldiers standing on the high wall suppressed the fire with heavy machine guns, and at the same time, the fighters carried out carpet bombing, and these ants with very low combat effectiveness instantly turned into a puddle of meat sauce, spreading a green carpet on the ground.

Xu Tian and Wang Feng stood in the distance and watched all this, Wang Feng yawned and said: "Looking at it this way, we don't need to make a move at all, and I don't know why the IQ of these monsters is so low, I know that they are going to die, but they still keep rushing up, it's really boring." ”

Xu Tianke is not as optimistic as Wang Feng: "I don't think it's that simple, through my observation during this time, I found that these green ants are just playing the role of cannon fodder, their number is very huge, they should belong to the inexhaustible kind, the purpose of their existence is cannon fodder, since there is cannon fodder, then there must be a conspiracy behind the cannon fodder, otherwise these cannon fodder will be meaningless." ”

Wang Feng disagreed: "They are just a bunch of bugs, how can they have such a high IQ, let's make a bet, if they can break through the first line of defense, I will admit that you are better than me, if not, you will stop claiming to be the first person on the earth in the future, how about it?"

Xu Tian didn't speak, but looked into the distance, and he saw that behind the green sea of insects, black dots appeared, and they were rapidly approaching.

As soon as Wang Feng finished speaking, he also took a look, and he also saw those black spots, which were huge crickets, which had fought on the previous bus, but Wang Feng didn't care, although these crickets were fast, they were not the opponent of the heavily armed regular army.

Those crickets soon arrived under the high wall, they wanted to jump on the high wall, but they were pressed down by the dense bullets, coupled with the constant bombardment in the air, everything was just as Wang Feng expected, these insects were no match for the army at all.

This time, Xu Tian and Wang Feng didn't speak, they both saw that a new species appeared in the sea of insects, it was something similar to an earthworm, their bodies twisted, and they quickly burrowed into the ground, very fast.

Wang Feng said: "Is this what they are for? Let the ants attract the attention of the military, and then let these earthworms quietly burrow into the ground and directly reach the interior of the city, but can such a method really hide from the military?"

Mo Yun, who was sitting in the command room, saw all this through the big screen, and a smile appeared on the corner of her mouth: "Hehe! stupid worm, do you think that we humans don't know anything about you? I will destroy as many as you come today." ”

Human scientists have studied these extraterrestrial creatures and found that they have nothing special about them other than their large size, and they are exactly the same as insects on Earth.

Scientists have made bold guesses about whether there are any species of insects on Earth, all of which are found in these alien creatures, and if so, then these monsters can be definitively classified.

Through observation, scientists found that these alien creatures are born to kill, and they divide labor according to the types of insects and the fields they are good at, forming a complete war system, knowing this, scientists can estimate the types of monsters according to the types of insects on the earth, and analyze what kind of combat they are good at, so the military has long expected that monsters will have varieties that burrow into the ground.

Those earthworms burrowed into the ground, and then made holes in the direction of Changchun City, but they couldn't continue to move forward without far, because there were rows of metal plates buried in the ground, and I didn't know what kind of material these metal plates were made of, and the earthworms couldn't penetrate at all.

Not only that, when the earthworms touched the metal plate, an electric current suddenly surged on the metal plate, which turned those earthworms into coke, which is why Mo Yun had no fear, after the scientists analyzed the types and characteristics of the monster, they immediately conveyed the information to the military, and Mo Yun had prepared everything, including a way to deal with the burrowing bugs.

Wang Feng put his mind at ease: "Hahahaha! I knew that the military would definitely be prepared, how about it, I won this bet." ”

Xu Tian ignored Wang Feng, his eyebrows were locked, he didn't know what he was thinking, Wang Feng glanced at Xu Tian, and just wanted to complain a few words, but he didn't say a word, his gaze and Xu Tian's gaze fell on the distance at the same time.

At the same time, the two of them saw that many huge things appeared in the green sea of insects, and those insects were already very large, but those things were even bigger, and compared to those things, the huge insects became ordinary.

"What's that?" Wang Feng asked, his vision could see the distance far away, but those things were too far away for his eyesight to see.

He couldn't see clearly, but Xu Tian could see clearly, and Xu Tian replied, "That's a bug, something like a beetle." ”

In Xu Tian's eyes, it can be clearly seen that it is a beetle-like creature, they are as tall as a hill, estimated to be more than twenty meters high, they have twelve legs, which can make them run like flying, they have a thick carapace on their body, Xu Tian estimates that it should be able to defend against hot weapons such as missiles.

"Maybe this is their real killer move!" Xu Tiandao.

"Yes, I'd like to see what's so great about these big bugs. Wang Feng said unremittingly.

Soon, those beetles were under the high wall, and as Xu Tian expected, no thermal weapon had any effect on it, and the missile could only hit a small spark on the carapace, which had no effect on it at all.

The indiscriminate bombardment in the air was equally ineffective against them, and these huge carapace creatures were like heavy tanks, crushing the corpses of their companions all the way to the vicinity of the high wall, and countless other insects died at their feet, which confirmed Xu Tian's speculation that they were cannon fodder.

The beetle had a pair of horns on its head, and they accelerated and sprinted, and with a bang, the horns above their heads slammed into the high wall, and the high wall shook for a while, and a long crack appeared in the wall, and if it was hit again, the high wall would collapse.

Mo Yun, who was sitting in the command room, saw all this, and he shouted into the intercom: "Use the photon cannon, and attack those beetles first." ”

Hearing Mo Yun's order, a strangely shaped cannon soon appeared on the high wall, this cannon is no different from an ordinary cannon, but there is an extra mirror on the top, which makes the cannon very weird, and this mirror is used to absorb photon force energy.
