The group rushed towards the city wall, and the sound of gunfire continued outside the wall, and the screams of the monsters became more and more clear in their ears.

"Damn! Who changed the plan. Nas ran towards the tall white city wall with all his might, and although Yan Yin could surpass him at will, he still chose to follow closely behind Nas for the sake of the captain's face.

"Turn on the gecko!" With 30 meters to go of the wall, Nas gave the order, and they quickly bent slightly, their hands pulling at the hems of their shoes seemingly lightly, and then, leaving a trail of blue fluorescent slime in their path.

For them, 30 meters is a blink of an eye.

Nearly 4 meters away from the city wall, they jumped up quickly and ran upright directly on the wall.

From a distance, there are five small black dots on the hundred-meter white city wall that rise straight up against the wall, and five blue stripes behind him are printed on the city wall.

"How long will it be before they arrive?" A blue-uniformed soldier commander aimed a sniper-mounted scope at a fast-moving, half-genetically ugly monster on the city wall, and a gunshot rang out, the monster fell, blood bloomed in the middle of his head, and he turned to question a bespectacled soldier holding a document.

"Report to the captain! They were supposed to arrive in 30 minutes, but they should be ...... when the biobarrier was removed" The Chief's eyes flickered, and a red shadow pierced the head of the soldier in front of him, and then shrank again, leading the soldier into the terrifying forest.

"Little belly! Nima's dog day ......" Suddenly a fleshy monster like a dog jumped on the city wall and interrupted him, the chief quickly pulled out the electric dagger from his waist, turned around and cut it diagonally, and directly cut the half-gene monster in half, and the colorful internal organs were left on the ground, looking very disgusting.

It was the long red shadow that shot straight at him, and the chief leaned back as if he had foreseen it, and the red shadow brushed in front of him.

He could see clearly that it was a blood-red tongue, the thickness of a man's arm.

The tongue blow did not hit the enemy, it stayed in the air for half a second, and then quickly retracted, and at the same time, another semi-genetized dog jumped up, and without any other movement, it pounced directly and bit the commander fiercely.

The Commander dodged the fatal tongue, followed by the fatal bite of a half-genetically dog, and while he was still leaning back, he flew backflips and got up to kick the half-genetically dog.

The gene dog was kicked into the air, and the end of its tail was pointed at what it thought was its prey, and suddenly there was a crack in its tail, and inside the crack was a light green eye, which stared at the chief tightly, and quickly turned red in the shortest possible time, as if something was being launched at any moment.

"'Laser Eyes'?! How can a semi-genetically modified dog do this? The chief thought, he had given up on dodging, for there was no way to dodge, and he closed his eyes, waiting for the Grim Reaper to take his soul.

"Huh~" A sound of breaking the air mixed with the wail of the gene dog fell off the city wall, and a figure appeared on the city wall first, followed by four figures.

The chief suddenly went limp, it felt so good to escape from death, and suddenly remembered something, and roared angrily.

"All squat!"

The five of them subconsciously obeyed the roar full of majesty.

They had barely crouched down when the blood-red tongue had just grazed their heads.

Yan Yin's eyes froze, and his left hand cracked and slashed towards his blood-red tongue.

The tongue is like a shadow, and the fissure is like a shuttle.

The blood-red tongue was cut out of an extremely long hole, and a few drops of blood were thrown out, and the red blood seemed to have an extremely strong corrosive ability, and it boiled when it fell on the white floor.

"Safe for the time being, that thing shouldn't be so easy to come back after suffering a loss, Barlow, if there is still a D-level 3rd order half-gene dog that dares to come up and kill it directly, Zhang Ye, snipe." Nas commanded, then looked at the Chief, who gave a simple military salute and continued to ask, "Chief, may I ask ...... the biological barrier?"

"The biological barrier was artificially canceled, and the strategy was temporarily changed, and the main battlefield was changed to the ruins of nearby cities, with the special army and the higher military academy as the main force, assisted by the graduating class of the middle military academy, and our pressure was reduced by 95% in an instant, taking advantage of the time to quickly replace the biological barrier."

"How is that possible? The group of D-class semi-alien beasts just now left a city and didn't eat it, and went to the so-called main battlefield, even if it was a monster that failed to genetize, it wasn't so stupid! ”

"Nope! What are they eating us for? ”

"Genetic mutations and a full stomach."

"And if there's something that you can use directly?"

"Direct utilization...... You mean! Nas exclaimed in surprise, and Yan Yin and Yu Xi also looked solemn.

"Yes, compared to what you guessed, it's 'Green Devil' gas, and besides, it's a 'Green Devil' tank compressed to the limit."

"Shhh......h To prevent the 'White Magic 71' incident? ”

"Yes, that was the biggest disaster in decades since the city was built, and nearly 60% of the humans in the White Devil Armor died, and now the fragile humans can't afford to die."

"Bang~" Zhang Ye fired a shot, and a half-gene dog that arrived in the distance fell to the ground.

"And what about our detailed mission?" Nas came back to his senses, and it was clear that he had wasted a bit of time.

"Ensuring that the city walls within 200 meters are not invaded, originally it was just a simple task, and the strongest is nothing more than a rare semi-genetized two-headed monster bird, even if I can easily do it alone, but! Something had just happened - the owner of the blood-red tongue had given up the temptation of the smell of the 'Green Devil' and was here intending to enter the city, while the rest of the area was defended by a few soldiers, and the defense was impenetrable, so the half-gene dog seemed to attack this area under the instructions of that guy. The chief stood slowly with his hands on the ground.

From somewhere in the forest, another blood-red afterimage shot at the newly emerged chief, who reacted quickly and took a step back in advance, and Nas and his party also reacted and drew their weapons.

The tongue brushed the chief again, Nas pulled out the red rock blade in his right hand and slashed it hard, but the tongue did not retract at all, and suddenly a fork stretched out from the side of the tongue, and shot at the center of the chief's eyebrows again at a speed several times faster than before.

"Sir!"

He collapsed in a pool of blood, and a snapping severed tongue landed beside him.
