For the existence of a super fierce man like Cheng Yanjin, it is definitely impossible for Ning Feng to hide it.

Therefore, Ning Feng is also willing to Cheng Yanjin to stand in front of the world, which will be easier for Cheng Yanjin himself, after all, with Cheng Yanjin's heroic character, he can't do low-key behavior.

"Shang Yun, that big man is Lao Cheng, he is the brother I met in the occupied area, if it weren't for Lao Cheng, I would be a pile of dry bones by now." Ning Feng pointed at Cheng Biting Jin and introduced to Shang Yun.

"Ning Feng, such a fierce man can be met by you, you are too lucky!" Shang Yun exclaimed.

Ning Feng smiled slightly and said, "Maybe!" ”

"However, now is not the time to discuss this, let's hurry back to the military district, so many green beetles come to attack, it is obviously a bit unreasonable, I feel that something big is about to happen!" Ning Feng continued to Shang Yun.

As Ning Feng said, more than a dozen fortresses have been built on the periphery of the military region, and there are layers of defense lines between each fortress.

Therefore, most of the monsters and zombies are fended off by these fortresses and defense lines, and it is difficult to get close to the walls of the military district.

Of course, if it's a monster that can fly and burrow into the ground, it can still break through the defenses of various fortresses.

However, there are not many monsters that can fly and burrow into the ground, and the relative defense is relatively weak, and the anti-aircraft guns and deep mines of the military district can easily deal with it.

Therefore, under normal circumstances, flying monsters do not come to attack the military region alone, only some flying monsters that are carried away by hunger will do such things as moths to the fire.

And this time, there were nearly a thousand green beetles, which is obviously an extremely abnormal thing.

The so-called abnormal things must have demons, and Ning Feng also had to be cautious and worried about this.

……

At this time, on the 50-meter-high wall around the military district, because they had been reminded by signal flares, countless sergeants were already waiting here.

"The green beetle is here! Everyone wait until the distance reaches 500 meters before firing! ”

Looking at the green beetles that were gradually flying in the sky, the general who commanded the battle also had a solemn face, but he conveyed the order extremely calmly.

Soon, the green beetle approached the high wall, and the high wall was also full of thousands of cannons, and countless anti-aircraft shells were fired into the air, heading towards the green beetle.

In an instant, half of the sky was filled with explosions and gunsmoke, and the stumps and flesh of various green beetles fell down like hailstones.

In just one salvo of artillery fire, more than half of the green beetles in the sky were lost.

However, the remaining green beetles did not stagnate, and still flew fearlessly, seemingly not caring about the death caused by the artillery fire.

This situation was beyond everyone's expectations.

After all, mutant insects are very timid, and they have never forgotten to die like this.

It turns out that with the advent of the apocalypse, many insects on Earth have mutated.

These different species of insects, after mutating, show seven different colors on the body surface, which are red, orange, yellow, green, blue, and purple.

Usually, mutant insects with a cyan body surface are generally insects that can fly, such as the iron-boned mantis that Ning Feng encountered before.

And this kind of mutated insects are also collectively known as green beetles, so the green beetles flying in the sky at this time are actually mutated by flying insects such as praying mantises, ladybugs, bees, and dragonflies.

Among the mutant insects, the most common are green and red, of which the green beetle is the most common flying insect, and the red beetle is the most common reptile insect.

Compared to these two colors of mutant insects, other colors of mutant insects are relatively rare.

However, mutated insects of other colors, although rare, pose a higher threat.

Most of these rare mutant insects have unique characteristics, such as being faster, having higher defense, being poisonous, and being good at burrowing into the ground.

For example, when Ning Feng and others took a helicopter to rescue Deng Lao before, the bone-eating giant insect that sprayed corrosive liquid to destroy the helicopter belonged to a type of purple beetle.

Purple beetles are highly venomous insects.

However, for these mutant insects, the military region has not paid much attention to them.

After all, mutant insects can pose a far less threat than infectious zombies.

Moreover, even though countless insects have mutated, the insects' natural fear of fire and sound has not disappeared.

Therefore, without the complex terrain of the city as a cover, mutant insects generally will not fight human armies head-on.

Therefore, the military region has never regarded mutant insects as a deadly threat to humans, and only regards zombies with faster evolution as the primary enemy at present.

Now, nearly a thousand green beetles are flying in, which makes the whole military region feel extremely puzzled, just because the attack of the green beetles is no different from sending them to death.

Although the number of nearly 1,000 green beetles seems to be very large, for the firepower network of the military region, it is actually only one or two rounds of salvo fire.

……

The people in the military region didn't understand why these green beetles came to die, but in a damp crypt more than 60 kilometers away from the military region, a strange giant insect with colorful body surface couldn't help but tremble slightly with excitement.

Because, those green beetles that attacked the military region were actually commanded by it.

This strange giant insect is not an ordinary mutant insect, it is the mother worm of mutant insects, and it is also the king of insects that will only be born out of millions of mutant insects.

Ordinary mutant insects, no matter how they grow and evolve, can only reach the limit of gold level.

However, the king of the Zerg in the mutated insects can grow and evolve to the platinum level, and even some insect kings with great luck can also evolve to the diamond level and become an existence like the insect emperor.

And the strange giant insect in this crypt is the insect king named "Colorful Beetle", and it belongs to the more potential of the insect king.

However, the evolutionary path of the Zerg is not smooth, and if they want to complete a huge breakthrough in strength, they must devour countless species with great genetic potential.

And the human beings who are weak and have great genetic potential are the best objects for the Zerg to devour, and the flesh and blood of humans are even more delicious, so that the Zerg are even more coveted by humans.

However, as the urban area of Rongcheng City has become a country of the undead, the nutrients needed for the evolution of the Colorful Insect King have also completely lost their source.

For this reason, the Spotted Insect King also fought the Shadow Undead, but it ended in a crushing defeat.

Therefore, the Colorful Insect King had to withdraw from the city and hide in this dark and damp crypt to recuperate.
