Seeing the zombie that could turn invisible and wield sonic attacks, with the number 17 clearly displayed on its forehead, Ye Feng was greatly surprised.
It turned out to be the experimental subject number 17 that had escaped from the Red Cliff ruins during his exploration there.
According to the records from the Red Cliff ruins, experimental subject number 17 was about two meters tall, originally a fifth-tier advanced zombie. It was captured by Joseph for experiments, and after being irradiated by the Divine Stone, it evolved into a sixth-tier zombie and became extremely ferocious, almost destroying half the base.
Later, Joseph suppressed it with nuclear radiation, but experimental subject number 17 underwent an unknown mutation, exhibiting a dependency on nuclear radiation, even consuming nuclear waste and attacking the nuclear reactor. It eventually disappeared to an unknown location.
"I didn't expect this experimental subject number 17 to end up here! This fifth-tier advanced zombie evolved into a sixth-tier zombie. Will its protective white armor disappear?"
Ye Feng glanced at a fifth-tier beginner zombie not far away, gnawing on a corpse with its entire body covered in white armor. His expression was serious, showing no signs of underestimation.
After all, experimental subject number 17 had once smashed a gaping hole in the nuclear power plant and escaped.
"Xiao Xiao, have you detected any nuclear radiation?"
Ye Feng frowned. He remembered that experimental subject number 17 had consumed nuclear waste.
"No!"
Xiao Xiao adjusted the radiation measuring instrument again and shook her head affirmatively.
"Altar~ Altar~ Altar~"
At this moment, a sharp female voice approaching from a distance attracted Ye Feng's attention. He turned his head and saw a one-armed zombie slowly moving forward.
"A third-tier mutated zombie... a Deceiver? Altar?"
Ye Feng frowned slightly, recalling the altar with four black sheep heads he had seen during the Goblin Kingdom era.
"Roar!~"
Experimental subject number 17 roared at Ye Feng. The dust swirling around it instantly spread out in a wave-like pattern.
"Bang! Hiss~ Crackle~!"
Ye Feng dodged to the side and, with a few leaps, found an opportunity. He threw several steel bars at the third-tier mutated zombie, the Deceiver, pinning it to the wall.
Ye Feng was quite interested in the altar mentioned by the Deceiver. He didn't want the Deceiver to wander off and hide in some obscure corner or disappear into the endless horde of zombies.
"Bang!~ Crash~"
After Ye Feng dodged the sonic attack from experimental subject number 17, it struck a load-bearing column. The concrete instantly shattered and was sent flying far away, and the thick steel bars inside were bent and dented.
"Roar!~~"
With a roar, experimental subject number 17 appeared before Ye Feng in the blink of an eye, punching towards Ye Feng's temple.
Ye Feng's eyes narrowed, and arcane energy instantly materialized on his hand, meeting the attack head-on.
"Bang!"
A dull thud sounded, and both Ye Feng and experimental subject number 17 retreated a step.
"This guy's physical strength isn't low at all without the white armor protection!"
Ye Feng was astonished. With the force of his previous blow, the armor of a battle tank would have likely been dented.
Yet, experimental subject number 17 only retreated a step and showed no signs of injury.
"Ding~"
"Detected peak sixth-tier zombie, 7 meters ahead!"
At this moment, the system's mechanical voice sounded.
"The system's prompt is really timely..."
Although this had happened many times before, Ye Feng couldn't help but feel speechless.
"Roar!~ Roar!~"
Experimental subject number 17 roared several times and lunged at Ye Feng again. Arcane energy manifested on Ye Feng's body, and he met the attack head-on without dodging.
"Bang!~ Boom!~"
"Clang! Bang~!" Roar~"
"Bang bang!~"
"Sizzle!~ Clang~"
...
Soon, the entire building ruin was riddled with holes, and craters appeared everywhere. Load-bearing columns were pierced through from time to time, and debris and steel bars flew about. Gunshots occasionally rang out.
Shortly after Ye Feng began fighting experimental subject number 17, the zombies that had finished eating corpses began to swarm towards Xiao Xiao, causing her considerable trouble, especially the two fifth-tier beginner zombies.
"Bang!"
Another dull impact sounded, and both Ye Feng and experimental subject number 17 were thrown back quite a distance.
"This guy is really unusually tough... Peak sixth-tier... Did Bing encounter this kind of thing before...?"
Ye Feng's expression was solemn.
After the exchange, he realized that experimental subject number 17 not only had extremely high physical strength, but its eyes were unharmed even after being shot, and it possessed strong combat skills.
"Hiss!~ Clang!~"
"Boom!~"
At this moment, Xiao Xiao was cornered by the two fifth-tier beginner zombies and other zombies. Debris and dust flew everywhere.
"Clang! Sizzle!~"
"Crack~ Sizzle~~"
After a burst of noise, Xiao Xiao emerged from the dust, wielding the Angel Blade Royal Command. The zombies that had been attacking her were already dead. She shook her head at Ye Feng, "I'm fine!"
"Roar~!!"
At this moment, experimental subject number 17 unleashed a sonic attack at both Ye Feng and Xiao Xiao, then ran away.
"It's running?"
Ye Feng frowned slightly and immediately pursued it quickly, with Xiao Xiao close behind.
"Gaa~ Roar!"
"Bang bang!~ Bang!"
Experimental subject number 17 didn't run far. It exited the ruins, let out a long howl into the sky, and then jumped onto a wrecked tank, tearing and smashing at its turret.
"Roar!~"
Within a few breaths, the tank's turret was ripped off by experimental subject number 17. It clenched the turret, roared, and charged at Ye Feng again.
Almost simultaneously, over a dozen fast-approaching figures appeared not far away. Several of them were covered in white armor, which were fifth-tier zombies.
"It's fourth and fifth-tier zombies... Did experimental subject number 17 call them over with its howl just now?"
Ye Feng's eyes narrowed. True essence materialized on his body, and he stomped on the ground forcefully, instantly vanishing from his original position and appearing before experimental subject number 17, punching it in the chest.
"Bang bang bang!"
Experimental subject number 17 was sent flying backward by Ye Feng's punch, crashing into the ruins.
"Big Brother, there's nuclear radiation, it appeared suddenly!"
At this moment, Xiao Xiao, who had just killed a fourth-tier zombie, shouted at Ye Feng. She had been paying attention to this.
"Hiss! Sizzle!"
As soon as Xiao Xiao's voice fell, a red beam of light shot out from the direction of experimental subject number 17. Ye Feng twisted his body sharply, barely avoiding it.
"Sizzle!~"
The red beam swept past, severing a steel gantry crane, which instantly collapsed.
"Laser?!"
"Can that experimental subject number 17 fire lasers?"
Ye Feng was extremely shocked. He had sensed movement from experimental subject number 17 and dodged instantly. If he had been a second slower, he would have been in serious trouble.
"Roar!~"
Experimental subject number 17 charged out of the ruins, appearing before Ye Feng in the blink of an eye, and delivered a spinning side-kick towards Ye Feng's ribs.
Ye Feng's eyes narrowed, and his true essence-infused fist smashed towards experimental subject number 17's chest again.
"What?"
As Ye Feng's fist hit experimental subject number 17's chest, his expression suddenly changed.
Because he sensed an extremely peculiar energy fluctuation, one that had caused him considerable trouble not long ago.
...
