As the flames dissipated, the figure in the raging flames revealed its original appearance, a human form with a whole body ** and the outer layer of the body was intertwined with black and red substances.

Duan Fei, who was in mid-air, closed his eyes, recalling the scene that had just happened on his body, he was slightly distracted because he was worried about the situation in Yanhuang Dacheng, even if he had the half-finished product of the Devouring Shield in front of him, he still stubbornly withstood the eighty percent attack of the flame cannon. Duan Fei, who had thought that he was waiting for his body to recover itself, never expected that at the moment when the flame cannon broke through the Devouring Shield and burned to his body, the one-third of the evolution key fragments actually flew out of the pocket of his clothes and stuck to Duan Fei's chest, releasing an unparalleled light.

Under this light, all the evolutionary power of the Evolution Key Fragment was poured into his body, and the Hellfire ability, which was the same origin as the Flame Cannon, was also induced, and just when he felt that his body was about to be burned into a roast pig by two waves of blazing heat from inside and outside his body, a cool feeling spread from the center of his eyebrows into his body, and spread all over his body.

Duan Fei, who was immersed in the cool feeling, didn't know what was going on, but the situation in front of him made his consciousness continue to choose to immerse himself in this comfort.

Only to hear the sound of 'crackling' from outside, Duan Fei, who woke up, saw a pale red light flowing in front of his eyes, and this pale red light covered his whole body and even his eyes. When I looked at it, I found that a power from the depths of the body was released and covered the body, and the flame cannon of the Flame Mutant Tiger was all converted into its own life energy, and the Evolution Key also activated the Hell Flame, evolving it into an ability that surpassed the B-rank.

The flames that now cover the body are the 'Flame Morph' upgrade to Hellfire's ability, Body of Hellfire.

Under the protection of the body of Hell, not to mention the mutant beasts of the late B-rank stage, including the peak strength, could not destroy it, even the monsters of the early A-rank could not destroy the body of Hell in an instant.

Looking at the changes in his body, there were more surprises than shocks in Duan Fei's heart, the evolution of Hellfire at this level meant that he was not far from A-level as a whole, and he believed that as long as he experienced another big battle, upgrading to A-level would be a matter of iron.

Looking at the dying Flame Mutant Tiger not far away, Duan Fei no longer needed to worry about it so much, all the life energy was used to launch the Flame Cannon, taking advantage of this emptiness, the Warrior Soul Thorn had been released to the final stage, even if it still had the strength, it was impossible to release any large-scale attacks.

The two fingers merged into the Hell Killing Sword, and rushed to the front of the Flame Mutant Tiger to slash in two stages, and the elephant-like huge Flame Tiger fell to the ground in response, and at the same time the flame crystal rolled down to the ground.

Although this battle absorbed the fragments of the evolution key that had been intended to be taken back for research to enhance the combat effectiveness of the Awoken troops, it unexpectedly obtained two unexpected gains, one was that the Hellfire ability successfully evolved to A-rank, and the other was to obtain a B-rank mid-stage mutant beast's gene core and a flame attribute crystal.

Just when Duan Fei wanted to lift the incarnation of the body of hell and spread his wings and rush back to the Yanhuang base, he found that the clothes he was wearing had already been burned by this hellfire, and once he lifted the incarnation, he would be bare.

After thinking about it, Duan Fei, who still forgot it, continued to maintain the state of Hell Incarnation, spread his wings and flew into the air with a bang, and flew towards the Yanhuang City in the distance.

Just when Duan Fei rushed back, the whole people in Yanhuang City were all soldiers, and people were panicked, looking up at the sky vigilantly, but no one knew what was going on. The sky that had been good until this time suddenly appeared like a large cloud of gray smoke and dust, and Yanhuang Dacheng, which was at the forefront of the human camp, did not dare to relax at all in the face of this sudden situation, but when the Awakened troops and armies were mobilized to the city wall, an incredible scene happened.

All the generators in the gray soot-covered area stopped working, not because they were out of order or because they were not powered enough, but because they simply stopped working. Soon, this strange thing spread to the entire Yanhuang City, and in the fog, all electrical appliances in the city, including radio, were shut down, and it was finally restored to the Yanhuang City, which could maintain the normal life of the survivors in the city, and returned to the state of resource emergency at the beginning of the apocalypse.

I don't know where the enemy is, no one dares to shoot indiscriminately, but the gloom around makes every soldier's heart tense all the time, if it weren't for the strict training before, we must always maintain a rational analysis, I believe that the entire Yanhuang City will be a mess now. As time passed, the concentration of the gray smoke also increased, and the situation within ten meters of the surrounding area could still be seen, but now, ten minutes later, even the gun in front of him could only see half of the outline.

The Awoken troops and armies that had already been sent out could only stand by in place, and in order to protect everyone in the team as much as possible, they formed a small formation with the Awoken troops as the center and the army as the outer circle.

Li Feng, who has the ability to shadow, is in charge of an extremely important role at this time, because his ability is not affected in this harsh environment, in order to stabilize the morale of the army, he repeatedly transmits information back and forth between the large army and the command center.

With Li Feng's ability, he could transfer the entire large army of foreign troops back in just five minutes, but in this way, the entire Yanhuang City became passive, not passive on the battlefield, but passive when attacked in his own base.

If everyone were to be moved to a safe basement, they would undoubtedly become caged birds, allowing monsters outside to destroy the entire base at will. I don't know if there will be no time for the people to escape. In order to maintain a state of relative confrontation, the large contingent outside cannot be transferred back, and must remain outside and be ready to fight at any time.

"Everyone! Can anyone tell me what's going on right now? The Luoyang City Lord, who rushed from the City Lord's Mansion to the command center through the tunnel, asked earnestly, "Is it a mutant beast?" ”

"The final work report of the virus detector shows that there is no large-scale virus movement within the monitoring range, this cannot be a mutant attack!" The head of the Virus Control Center replied.

"Drones dispatched out of the country can't transmit information back, and we have no way of knowing if this is the only one happening at our base!" At this time, the deputy captain of the reconnaissance team also said.

"The current situation shows that all machines that run on electricity cannot work, and we are now a lonely city!" Patting the closed display in his hand, the head of the Resource Management Office said disappointedly.
