After Han Feng found that the mutant zombie could be invisible in the air, he opened his eyes wide and searched around the Unimog RV several times, but he couldn't find the trace of the invisible zombie again.

However, when his gaze swept over Wu Yuli, who was also seriously looking for the invisible zombie, an idea came into his mind.

"Wu Yuli, you try to use your evolution ability to observe our surroundings and see if there are any abnormal energy points of light?"

Han Feng wanted to use Wu Yuli's energy observation ability to try to find the invisible zombies lurking nearby.

Wu Yuli, who was sitting in the driver's seat and constantly looking outward with her eyes, heard the voice coming from her, and immediately nodded her head and exerted her evolutionary ability.

However, she had only used her evolution ability for a moment before she opened her eyes again.

"No, I don't know what's going on in this whole area, I can only see a whole area of energy spots, this energy spot completely covers other energy spots, in this area, I can't observe any energy spots."

After hearing Wu Yuli's response, Han Feng sighed slightly, and then shook his head helplessly.

He tried to let Wu Yuli use the evolution ability just now, but it was just a way for her to try her luck, since Wu Yuli couldn't observe the location of the invisible zombie, then he could only take the second plan.

"You stay in the RV obediently and don't move, I'll lure out that invisible mutant zombie."

At present, Han Feng can only use himself as bait to lure the invisible zombie and take the initiative to attack him.

As long as the invisible zombie is willing to come out, that's fine.

He believed that with the strength of his gold-level evolutionary, even if the invisible mutant zombie launched a surprise attack on him, then with his strength, he was still very confident of dodging it.

"I see!"

Wu Yuli nodded her head slightly, and found that Han Feng opened the door on the right side of the RV and left the Unimog RV.

And he also took a few more steps forward, and waited until his body was completely out of the protective distance of the RV energy shield system, and then slowly stopped.

When Han Feng stepped out of the protective distance of the RV's energy shield system, the surroundings seemed unusually calm, and Han Feng who was standing in place could only hear the sound of his own breathing.

But at this moment, Han Feng suddenly found that a strange fluctuation appeared in the space behind him, and a trace of undetectable breeze made the hairs on his arms tremble a few times in a way that was almost invisible to the naked eye.

"I can't help it!" After Han Feng felt the spatial fluctuations from behind him, the expression on his face did not change in the slightest, but a trace of joy appeared in his heart.

For this invisible zombie that comes and goes without a trace, the most important thing is to lure this zombie out.

As long as this invisible zombie is exposed, its body is exposed.

Then there are a hundred ways to solve it easily.

Just when the hair on Han Feng's arm was blown by a breeze, a right arm with a sharp barb on his nail appeared behind him.

If Han Feng didn't react at this time, then his body would be pierced by this right arm with a sharp barb in the next second.

But at this time, Han Feng moved!

I saw that he was holding the Dark Moon Long Knife in his backhand, and at the same time, his entire body was like a cheetah, pounced on the invisible zombie behind him that had just emerged from the void.

"Shhh

The invisible zombie also seemed to be startled by Han Feng's movements, it let out a roar, quickly retracted its outstretched right arm, and its entire body disappeared into the air again.

However, Han Feng was a gold-level evolutionary who was known for his speed, and in the case of mental calculation or unintentionality, it was naturally impossible for him to let that invisible zombie return to the void.

I saw that his right arm holding the Dark Moon Long Knife slashed at the mutated zombie who had just re-entered the invisible state at a lightning speed.

"Poof!"

With a crisp sound.

An arm with a large amount of black blood in the void was directly cut off by the Dark Moon Long Knife, and the entire severed arm appeared from the void and smashed to the ground.

And Han Feng also looked at the void, where blood was constantly spurting, and firmly locked the position of the invisible zombie.

"Give me death!"

Through the blood sprayed from the invisible zombie's body, Han Feng, who locked the location of the invisible zombie, let out a heavy cry from his mouth, and at the same time, with all his strength, he swung a fatal blow into the void.

A pitch-black spatial rift appeared in the secret base, and in the void covered by the spatial rift, two bloodless legs suddenly fell, and as for the other body parts of the invisible zombie, it seemed to be completely engulfed by the spatial rift.

"It's a loss!" When Han Feng saw that in the void, only two bloodless zombie thighs had fallen, and after the other parts of the zombie were swallowed up by the spatial rift, he suddenly let out a sound of annoyance.

He clearly overestimated the strength of the invisible zombies.

That invisible zombie is only at the level of the silver level at most, and the zombie of this level is obviously unable to make a little defense against an attack of this level of the spatial rift.

Therefore, the spatial rift that Han Feng swung out completely engulfed the entire invisible zombie's body except for the thighs.

And the zombie crystal nucleus that every mutant zombie possesses is naturally swept into the spatial rift along with the head of the invisible zombie.

However, Han Feng was only depressed for a moment, a silver-level zombie crystal nucleus was not a big deal for him now.

After he dealt with the invisible zombies, he was silent for only a moment, then raised his head again and looked behind the 1130 close defense gun.

Behind the 1130 anti-aircraft gun, there is a huge underground space, and on the left side of this space, there are small rooms that are densely divided into offices, which are obviously the offices and experiments of the scientists in charge of the Large Hadron Collider.

On the right side of the whole space, there is a huge building, firmly enclosed with a concrete sarcophagus, this building, there is only a small door for three people to enter at the same time, and a thick energy transmission pipeline extending from the sarcophagus to the middle of the space.

"I didn't expect that in the secret base under the old site of Atomic City, there was a small nuclear reactor that was shut down." When Han Feng saw the three-leaf radiation warning sign engraved with black letters on a yellow background on the sarcophagus, he understood that a small nuclear reactor should be sealed in the sarcophagus in front of him.

At this time, Wu Yuli, who found that the invisible zombies had been solved, also drove the Unimog RV to Han Feng's side, and then she shouted to Han Feng through the thick window glass: "Boss, do you need any help?" ”
