The strength of the biochemical beasts in the battle under the city has gradually become weak, and the number and quality of mutants have the upper hand, Qin Feng saw that a second-level biochemical beast had just stabbed a first-level mutant with a bone spur, and a giant axe next to him suddenly fell from the sky and slashed into his skull, and a mournful sound resounded throughout the battlefield, although they did not have the main consciousness but the basic neural induction was there, in fact, if the pain sense was removed, it would be a better killing machine, but there was not enough time to finish all this.

Qin Feng saw that Kang Shuai and the others had returned to the position of the second line of defense, so he no longer waited, he instantly collected all the laser cannons into the ring, and the firepower on the city wall suddenly weakened, without the suppression of the laser cannons, the pressure of the war beasts in the distance increased dramatically, and it was estimated that he would not be able to hold on for more time.

Qin Feng looked back at the leader of the mutants as if he had a chance to win, and walked up slowly after all the mutants, just now the laser cannon focused on taking care of it a few times, but the other party's speed was amazing, and he could always dodge it when the beam hit it, so after a few times, the laser cannon began to continue to take care of the other mutants, and the leader of the mutants was really difficult.

Leaping forward, Qin Feng jumped off the city wall, and then didn't care about the battle in front of him, and immediately boarded the vehicle left behind, the engine roared, and the off-road vehicle suddenly rushed out of the way and immediately drove towards the formation.

Qin Feng drove the car and immediately broke into the position from the side, but he suddenly opened the car door and jumped out, while the front part of the off-road vehicle was suddenly hit hard, and the body suddenly rolled and leaped under the inertia, and then exploded into a piece of debris.

All the soldiers on the second-line position exclaimed in the face of all this, no one expected that such a thing would suddenly happen, is this still the rear? How could the flames of war suddenly spread here?

Li Shaobing immediately began to look for Qin Feng's figure, but the fireworks and dust were flying, and he couldn't see clearly for a while.

"I'm fine, Li Shaobing, you hold your position, the most dangerous guy has come in." Qin Feng already knew at this time that it was the mutant leader who caused all this, and he seemed to have underestimated it, but he didn't expect the other party's speed to be so fast, and in an instant, he had already jumped onto the car and completely destroyed the off-road vehicle.

In the midst of the flames, the figure that was surprisingly short among the mutants was very huge, and a cold black shadow appeared behind it, looking so terrifying.

However, Qin Feng is full of fighting spirit, and now everything on the battlefield has been handed over to Li Shaobing to command, and his enemy is only the leader of the mutants, and if he gets rid of it, the biggest threat to the base can be removed.

Just when Qin Feng and the leader of the mutants were confronting, Li Shaobing ordered the plasma cannonballs to prepare to bombard the position of the gate of the city wall, and it was shown through the video system that all the biochemical war beasts had died, and the battle of the first line of defense eliminated a total of eighty percent of the mutants on the other side, leaving only three second-level and four first-level mutants, and the injured had already all died, and the mutants were never afraid of death, they were born to fight, until the moment before death.

The gate made of stainless steel was easily chiseled through by the battle axe in his hand like paper paste in front of the powerful second-level mutant, and the next moment the gate was already crumbling.

"Fire!" With Li Shaobing's order, the plasma cannon was excited at its maximum power, and the plasma bomb glowing with blue light roared towards the gate, and when it touched the gate, the plasma suddenly lost its restraint and began to become disordered, and then burst out of its own energy, a big explosion directly blew up the gap in the city wall, and the rocks at the mountain pass were also vaporized under the huge energy, and the nearest three mutants directly turned into ashes, and the killing of this blow alone contained two second-level mutants.

Seeing this real-time battle situation, all the scientific researchers who had already been hiding all cheered, in their opinion, this battle was about to be won, but they didn't know that Qin Feng was already fighting with the powerful enemy he had encountered at this time.

The leader of the mutants was also holding a sharp sword, and after fighting hard with Qin Feng twice, he glared angrily at Qin Feng: "You killed my warriors and robbed me of food, I want you to die!" ”

Qin Feng didn't have a trace of surprise that the leader of the mutants was able to speak again, the wisdom of the third-level mutants was already not much lower than that of ordinary people, they re-evolved, and the tissues of their bodies underwent unpredictable mutations, not so much as human beings, but towards a new race, if it weren't for the fact that the other party's body was too mutated and his face was a little hideous, you would definitely think that the other party was a normal human.

What's more, the leader of this mutant has further mutated, and the adventures it has obtained have accelerated his evolution to the level of a fourth-level mutant, although it has not yet reached the threshold, but it is much stronger than a third-level mutant.

"It's useless to say this, it doesn't matter if it's right or wrong, the important thing is to live, and it's better for your subordinates to see the truth if you have anything to say." Qin Feng has long regarded the other party as another species, what is there to talk about, either you die or I die.

Qin Feng's legs were already full of strength, and as soon as he finished speaking, he stepped forward with a brisk step, and his momentum was suddenly great, and he had already slammed the sharp horizontal knife attached to the opponent's neck, and the angle was extremely tricky, seeing that victory was just around the corner.

But the next moment Qin Feng was disappointed, he didn't expect the mutant leader to suddenly lean back, and the long sword in his hand stabbed at Qin Feng's wrist, which dissolved Qin Feng's fierce offensive and made Qin Feng have to turn around to rescue, the long sword and the horizontal knife collided together again, and sparks flew everywhere. This is not at all like the mutant big open and moving forward, but it is as sharp as a swordsman.

"How did you do that?" Qin Feng was very curious, he couldn't help but stop his attack and wanted to get some information from the mutant leader, the unknown is always frightening, if the mutants can evolve like this, then how can there be room for human survival.

"Hey, hey, you can't think of it~" The mutant's laughter was as piercing as a night owl in the night, making people hear a burst of brain pain.

"You want to know, it doesn't hurt to tell you, there is a lumpy solid that can increase the intelligence and strength of mutants, and at the same time give me new abilities, do you know why I can use my sword so purely? I ate Huang Jiachong's brain. "The mutant seemed to feel that the victory was in hand, and he spoke with a sense of showing off.

Qin Feng was stunned, this Huang Jiachong is a swordsman in Zhejiang Province, his swordsmanship is superb, he is known as a sword idiot, how could he die here and be devoured?

So it seems that today is not easy to pass,
