When the hen's mouth is filled with liquid in a glass bottle.

The hen stood still for about a dozen seconds, and even flapped her wings a few times leisurely.

But after a short dozen seconds, the terrifying mutation began.

"Giggle——!

The hen raised her head and let out a terrible roar.

Then its body swelled up like a balloon, and the feathers on its body began to slowly detach from its body.

Han Feng, who was sitting in the Unimog RV, looked at the hen in front of him who had mutated, and a fine light flashed in his eyes.

While the hen's body swelled, the surface of the featherless body bulged high, and the claws under her feet began to grow sparkling spikes.

Han Feng looked at the hen in front of him who was poured with a suspected strain of the apocalyptic virus, and began to mumble in his heart.

"In this hen's body, the momentum that erupted became more and more amazing, it only took less than five seconds for it to change from an ordinary creature to a bronze-level mutant beast, and after half a minute, it had broken through the boundary between bronze and silver, and became a genuine silver-level mutant beast, and now it was actually ready to break through to the gold level."

However, this time it was to test what the effect of the extracted material from the corpses of the members of the Lan Air Guard was Han Feng still suppressed the urge to do it, and looked at the hen in front of him, and the momentum on his body increased step by step.

With a circle of black light, it shone from the hen's body.

The momentum around its body has finally reached the gold-level level, and after this hen has taken the extract obtained from the corpses of the members of the Lan Sky Guard, it has actually completed several jumps directly, breaking through the two major stages of bronze and silver all the way, and directly becoming a gold-level mutant beast.

When the mutant hen, who had already consolidated the momentum of her body at the gold level, raised her head again and let out a hiss.

It turned its gaze directly to the only source of energy in this red desert, the Unimog RV.

"The 75mm microwave laser automatic rapid-fire cannon is activated!"

In the face of the incoming gold-level mutant hen, Han Feng, who was sitting in the RV, did not have any nervousness, he directly activated the microwave laser automatic rapid-fire cannon on the car, intending to test the defense of this mutant hen first.

Four microwave lasers glowing with orange-red light shot out from the top of the RV and directly hit the body of the gold-level mutant hen.

However, just as the microwave laser was about to hit the body of the mutant hen, a black light emerged from the surface of the hen's body, and when this black light appeared, the attack launched by the microwave laser automatic rapid-fire cannon was completely neutralized.

Just when the microwave laser automatic rapid-fire cannon was in vain, the attack of the mutant hen also arrived.

The black light around it actually broke away from its body and hit directly towards the location of the RV.

"It has a long-range attack capability, and it doesn't seem to be low-powered." Facing the incoming black light, Han Feng, who was sitting in the RV, was still observing expressionlessly.

While Han Feng was observing, Unimog RV naturally reacted to the incoming black light.

The Energy Shield system is automatically activated.

A pale blue shield appeared on the surface of the RV, wrapping the entire RV tightly inside the shield.

"Zila——!"

With a strange sound when the energies collided with each other, the black light emitted by the mutant hen and the energy shield system of the RV began to cancel each other out.

On the surface of the energy shield system directly in front of the Unimog RV, there were waves of waves, and when this wave appeared, Han Feng immediately lowered his head and glanced at the instantaneous consumption of the energy shield system.

"It actually consumed thirty percent of the shield strength in an instant, and it was really the attack strength of an authentic gold-level mutant beast."

When Han Feng saw the LCD screen on the center console of the RV, the index representing the energy shield system was instantly missing three squares, and his face also showed a solemn look.

"The Heavenly Death Yang Electronic Cannon is activated!"

When he finished testing the attack and defense of the gold-level mutant hen, and it was indeed a genuine gold-level mutant beast, he directly activated the Tianyanyang electronic cannon located on the top of the RV.

He didn't come here to be beaten passively, since he had already tested the extract obtained from the corpses of the members of the Lan Sky Guard, what effect was there, and he also tested the gold-level mutant beast in front of him, in such a short period of time, from an ordinary creature to a gold-level mutant beast, what would be the difference between it and other gold-level mutant beasts.

The gold-level mutant beast in front of him that was used for testing could naturally die.

After the launch button of the Tianyang electronic cannon was pressed, a huge amount of energy began to converge on the top of the RV.

However, just when the reddened energy in the white appeared in the muzzle of the Heavenly Death Yang Electronic Cannon, ready to shoot out towards the gold-level mutant hen.

Han Feng also discovered that this gold-level mutant hen was different from other gold-level mutant beasts.

The gold-level mutant hen in front of him, facing the threat of the Heavenly Death Yang Electronic Cannon, actually turned around and fled, when its two long legs with spikes grabbed the red dirt on the ground and flew back, Han Feng's face finally appeared a look of surprise.

It was more than he could have imagined.

Generally speaking, although gold-level mutant beasts will have the intelligence of human children as young as 2 or 3 years old, this level of intelligence cannot cancel out their basic rules of action by instinct.

Therefore, these gold-level mutant beasts usually act on their own instincts, and generally they will fight to the death, no matter what kind of attack the opponent launches, they will fight the opponent to the end.

But this time, the gold-level mutant hen, after feeling the power of the Tianyang electronic cannon, actually chose to take the initiative to evacuate, and this alone broke Han Feng's habitual thinking and became a little interested in the gold-level mutant beast in front of him.

However, after the firing button of the Heavenly Yang Electronic Cannon was pressed, Han Feng had no way to forcibly reverse the firing procedure of the Yang Electronic Cannon.

When this beam of energy reddened in white flew out from the muzzle of the Heavenly Death Yang Electronic Cannon, Han Feng sighed helplessly.

He had never seen an existence that could directly resist the Heavenly Death Yang Electron Cannon with his physical body, and the huge amount of gamma ray destruction contained therein.

Sure enough, when the body of the gold-level mutant hen that flew away was hit by the Heavenly Death Yang Electronic Cannon containing a huge amount of gamma rays.

The surface of its smooth body instantly flooded with black blisters, and the Heavenly Death Yang Electronic Cannon, which carried a huge amount of gamma rays, had begun to destroy its body.
