Carl turned his gaze back to Leo, who shook his head again, indicating that he hadn't heard anything strange.

"How so......" Karl frowned, looking out of the walls again. He distinctly heard a lot of sand rubbing in the thick red mist, and the sound of something chewing and eating.

But outside the walls of the Punk Fortress, in addition to the corpses of the Zerg everywhere, only a large number of Zerg who have not died are left.

"That's not right! There must be something under the walls! Karl was very sure of his guess, and his right hand tightly grasped his war spirit weapon.

When he noticed that the soldiers beside him were also not slackening, his heart calmed down a little.

The strange sounds under the wall continued for a while, and then suddenly there were many strange roars, which suddenly made the group of people on the wall tremble.

"It's coming!" Old Bill said in a deep voice, and from the constant trembling of his arm holding the gun, it could be seen that his heart was also not easy.

Boom! Boom! Boom!

Carl just wanted to speak, but Leo and John beside him also showed a frightened expression, it seems that this time, everyone can hear the voice!

"Attention, down there!" Old Bill squinted his eyes and looked at the city wall with a serious expression, and after a short 3 seconds, his face changed drastically and he directly ordered to fire.

"It's a six-legged beetle! Damn bugs, would they want to take advantage of the red mist to rush to the city walls? John spat disdainfully and pulled the trigger of the Carlin machine gun in his hand.

It's just that after the soldiers have been shooting for a while, Karl suddenly realizes that something is wrong!

"No, the number of bugs on the wall this time is too small, if you just rely on six-legged beetles, isn't it better to have as many as possible?" Karl said with an ugly face.

"Carl, the situation is not right, the six-legged beetle that came up this time is not moving at the same speed as before! Just a moment, it's already halfway there! ”

"And...... What is that abnormal glossy color on their surface? At this time, Leo also discovered the peculiarity of the enemy.

After Carl heard this, he also noticed that the surface of this group of six-legged beetles was glowing with an abnormal luster color, and it was obvious that this group of six-legged beetles was not an ordinary flesh armor level!

"It's over, what's the matter, the bullets from this Carlin machine gun hit those bugs, and they all bounced off! Except for being able to block their progress, none of them have been solved! John fired for a moment and said incredulously.

"Damn, this group of insects has actually completed their evolution, and they are iron-level six-legged beetles! So, what are you waiting for! Flamethrower, Spray! Old Bill roared angrily.

The soldiers, armed with flamethrowers, immediately erupted into the city walls.

However, this group of six-legged beetles has evolved to the iron armor level, not only is their movement speed super fast, but the flamethrower is completely unable to accurately capture their figures, even if they are barely sprayed by the flames, they will not be burned into ashes in an instant like the meat armor level.

"No, it's already up!" Karl frowned, and quickly took a few steps forward, pulling John and Leo back several steps with great force.

The two were caught off guard, and before they could say anything, the scene in front of them suddenly frightened them and shut their mouths.

On top of the battlements of the city where the two of them had just stood, there was a six-legged beetle with teeth and claws, waving its sharp claws angrily.

Looking at the ordinary soldiers next to them, they were not so lucky, many ordinary soldiers who didn't have time to react were pierced by their sharp claws almost instantly, and then the whole person was thrown far away from the city wall.

"Don't back down! Knock them off! Old Bill picked up his gun and blasted a six-legged beetle in front of him off the wall.

At this time, it reflects how terrifying it is to evolve into an iron-armored six-legged beetle. If the lethality of human guns and ammunition is insufficient, it can only cause a knockback effect, and it is completely unable to effectively kill the iron-level hexapod beetle.

"Sir! More six-legged beetles are climbing up the walls! "A soldier, at the risk of being killed, rushed to the battlements of the city wall to detect it.

"This is too bad, if this wall is lost, it is very likely that the defense of the Punk Fortress will be leaked, and then it will collapse completely!" Leo shouted in fright.

Carl glanced back at Egger, but the latter did not show any panic, such a gesture gave Carl a shot in the arm.

That's right, this is also a punk fortress, a military fortress that has stood on the border of the Gamma Empire for I don't know how many years, how could it be completely defeated because of such a thing?

At this time, Iger also looked at Carl, and the eyes of the two intertwined in the air for a moment, and Carl nodded, as if he understood something.

"Hey! Leo, John, you two cover me, these evolved six-legged beetles, all of them will be handed over to me, but my battle spirit power may run out, you must remember to protect me safe! ”

"Don't worry!" John finally got up from the ground, and in just 30 minutes, he had already brushed shoulders with death twice, and his mentality had inadvertently become a little stronger.

Carl nodded and shouted in his heart, "Kidd, come out for me!" ”

Hearing this, Silver Bullet Kidd appeared beside Carl with a smile and asked curiously, "Didn't you want to deal with this group of six-legged beetles alone, why did you suddenly call me?" ”

"Hmph, don't talk nonsense, I just want to ask, is there any way to move quickly, and also shoot bullets that can break through the iron-level defense."

"So that's the case, the attack methods you have learned so far, the silver explosive bomb and the silver dragon two-legged bullet, the three combat skills on the screen, don't seem to be suitable for use here."

"Nonsense, I just don't have any other way, that's why I asked you!" Carl shouted dissatisfiedly, time is already pressing, this guy is still selling here!

Kidd smiled lightly and said casually: "It's very easy to deal with this group of bugs, and you can solve it with the fast gun fighting technique you currently master!" ”

"Quick gun fighting? But isn't that move just shooting faster, these insects have evolved to the iron armor level! Carl was shocked.

"Hmph, who told you that the fast gun fighting technique is just an ordinary shot that is relatively fast? Boy, it seems that you have a big misunderstanding of the gun fighting skills I taught you! Kidd sneered, unhappy with Carl's answer.
