Since Lu Yu was bent on sawing off the head of a phase-level zombie, he didn't have the idea of the expression on Zhang Ning's face at this time, and just walked towards the fire escape by himself.

The door of 2901 was wide open, and Lu Yu soon walked into his home.

The house was empty, and all the food and water, as well as some useful tools, had been moved downstairs.

didn't have time to sigh, Lu Yu relied on his previous memories and quickly found the toolbox left by his father and took out a hacksaw from it.

Lu Yu remembered that because his father was a lover of ancient weapons, he often dealt with some materials such as metal and wood, and because the family could not arrange large lathes, many parts could only be completed by hand.

And this hacksaw is one of the tools that my father used to do when he was doing handicrafts.

"A saw that can cut through round steel, presumably there should be no problem with sawing through the cervical vertebrae of phase zombies."

Lu Yu's figure soon appeared on the rooftop again, although his house was only one story away from the rooftop, Lu Yu still trotted all the way, for fear that something would happen to the zombies.

Fortunately, everyone stood on the rooftop safely, although everyone's faces were not very good.

Yan Yan Ben seemed to have vomited up the breakfast he had eaten in the morning, and was leaning against the wall and looking at Lu Yu weakly, his eyes full of fear and doubt.

The fear was because Lu Yu's previous cold-blooded appearance of chopping his head had left him with a psychological shadow, and the doubt was that he wondered why Lu Yu was holding a hacksaw in his hand.

"Boss, I'm back, this phase-level zombie doesn't react, right?"

Lu Yu walked quickly to Zhang Ning's side and asked in a low voice.

"It's okay, your neck has been chopped like this, I guess I'm dead......"

Although Zhang Ning is timid, his psychological quality is still very strong, and during the time when Lu Yu went downstairs to get tools, he had already adjusted his mentality.

At least the speech doesn't tremble anymore.

"Hmm."

Lu Yu nodded, half-knelt beside the body of the zombie, pressed the zombie's chest with one hand, stepped on the zombie's head with one foot, and began to creak and saw.

"Gross!"

Yan Ben, who had finally recovered with great difficulty, saw the terrifying scene in front of him, and suddenly felt a churning in his stomach, and hurriedly returned to the corner and began to vomit.

The hacksaw sawed on the bones of a zombie of the same level, and there was a feel like sawing on metal.

"This bone is so hard?"

Lu Yu was slightly shocked in his heart, but the strength in his hand did not decrease, and he sawed down hard.

With his continuous efforts, the cervical vertebrae of the phase level zombie were finally sawed in, and Lu Yu keenly found that the originally smooth and lifeless saw blade had some lilac liquid on it.

"Is the fluid in the bone marrow brought out by the serration? How is this color ......"

Lu Yu muttered in his heart, but the movements in his hands did not mean to pause at all.

He didn't care what color the bone marrow fluid would be, his purpose was to completely separate the head of this phase zombie from the body.

Judging from Lu Yu's only experience in killing zombies, beheading zombies should be regarded as a way to completely destroy their heads, since pawn-level zombies can be completely killed by this method, then the zombies of the same root and origin must also be killed!

But just when he was concentrating on sawing bones, Zhang Ning, who had been quietly observing, suddenly shrugged his nose, and then, like a wolf dog searching for prey, kept sniffing around.

"Do you smell a scent......

Zhang Ning shrugged his nose and patted Xu Xiaoxiao beside him.

"Scent? What a scent, no......"

Xu Xiaoxiao frowned and subconsciously sniffed twice, but there was only a faint smell of corpses entering his nasal cavity, and there was no fragrance.

When Xiao Ran heard Zhang Ning's question, the bright mandarin duck's eyes became empty, glanced at the phase-level zombies on the ground, squatted down, patted Lu Yu, and signaled him to pause the action of sawing bones.

Stopped by Xiao Ran, Lu Yu looked up at the little Lori in front of him, showing doubts.

Xiao Ran didn't talk nonsense, he directly took the hacksaw in Lu Yu's hand, put the saw blade in front of Zhang Ning, and spoke.

"Brother Zhang Ning, did the fragrance you smell come from above?"

As he spoke, he handed the saw in his hand under Zhang Ning's nose.

"Hmmm! Yes, that's what came from above! ”

Zhang Ning took the saw, regardless of the fact that it was covered with minced meat, and sniffed it vigorously, like an addict who was used to smoking big cigarettes, he breathed a long sigh of relief and said in surprise.

As he spoke, his right index finger poked out, as if trying to touch the purple liquid on the saw blade.

"Smack."

A slender palm slapped off Zhang Ning's index finger that wanted to stretch forward, Lu Yu took back the hacksaw and rolled his eyes at Zhang Ning.

"Don't be in a hurry to study this bone marrow fluid first, the head of the phase level zombie has not been sawed off, and it may come back to life and kill us at any time, be safe, when I completely repair it, there is time for you to study."

The creaking and creaking saw sound sounded again, and everyone, including Zhang Ning, stood aside and waited silently.

Lu Yu's seemingly unreasonable action not only did not arouse Zhang Ning's disgust, but made him have a little respect for Lu Yu in his heart.

Being focused, and thoughtful, is definitely a plus as a leader.

After about ten minutes, Lu Yu finally sawed open the zombie's cervical vertebrae, kicked the head of this zombie of the same level two meters to the side, and then sat on the ground with a sigh of relief.

The bone marrow fluid slowly trickled out from the fracture, sticky and not like liquid, and pooled into a fist-sized puddle of lilac water on the floor of the rooftop.

Zhang Ning took a deep breath again, his eyes lit up, and he squatted quickly next to the pool of purple lilac liquid.

This small pool of liquid, for Zhang Ning at this moment, is like a fairy beauty, frantically seducing him closer.

But Zhang Ning still stabilized his mind, and after adjusting his breathing, he pressed his entire palm into the lilac liquid.

That is, the moment the skin touched the liquid, Zhang Ning trembled, as if he had touched the electric door, but looking at the expression on his face, there was no trace of pain.

"Cool!"

When Zhang Ning's skin touched the lilac liquid, a burst of coolness came from the palm of his hand, like a river flowing into the sea, along his forearm, and quickly entered his body.

When the exhilarating sensation was gone, the puddle of lilac liquid under his palm was gone, and there was not even a trace of dampness, as if it had never existed.

"Sure enough, it was absorbed again. This thing is really good for you......"

Among the people who watched the whole process, Xu Xiaoxiao took the lead in speaking.

After all, she had seen the scene where Zhang Ning absorbed the black liquid in the zombie's brain before, and at this time, seeing that the bone marrow fluid was also absorbed by Zhang Ning, she felt a sense of course.

Lu Yu and Xiao Ran looked at Zhang Ning with a look of surprise, although they knew in their hearts the special features of Zhang Ning's body, but from speculation to personal confirmation, it still brought them a big shock.

"Eh, you say, can you also become stronger like those zombies, by swallowing the black liquid in the brains of your kind?"

Lu Yu seemed to be interested, with a sly look, and his eyes still looked at the head not far away from time to time.

"you, I'm not going to eat that......"

Zhang Ning pretended to be angry and made a gesture to beat Lu Yu, but he didn't want to say it, his body was still very honest.

After a while, Zhang Ning had the head of a phase-level zombie in his hand.

Lu Yu handed over the hacksaw in his hand, and gave Zhang Ning an encouraging look by the way.

"Come on! Lift its skull! ”

Zhang Ning glanced at everyone with complicated eyes, and found that everyone was looking at him with a curious gaze, which felt like watching a monkey in a circus.

"Squeak Crunch ......"

The monotonous grinding and sawing sound sounded again, and the skull of the phase zombie seemed to be much easier to saw, compared to its cervical vertebrae, Zhang Ning didn't take long to saw the head in his hand, and suddenly, the black liquid flowed to the ground, revealing the empty skull inside, and a brain that shrunk to the size of an orange.

The brain was pierced by a yellowish cone, sinking to a depth of about a centimeter.

"Hey, with such a small brain, it's no wonder that the IQ of this zombie is not very ......."

Lu Yu complained on the side, at this time, he had completely lost the momentum of the perverted butcher just now, and he was just a street chattering old mother, judging the body of the zombie, and there was a bag of melon seeds in his hand.

Zhang Ning pressed his palm on the black liquid as before, but this time the pleasant feeling did not come, replaced by a slippery and greasy feel.

It felt like he had put his hand in the sticky stool......

A wave of goosebumps centered on his palm, spreading towards his body.

After lasting for about five minutes, the black liquid on the ground did not decrease in the slightest, and Zhang Ning's body did not change at all.

"It's weird, why didn't you absorb it?"

Xu Xiaoxiao touched his smooth chin and asked curiously.

"This ...... It's not something I can control......"

Zhang Ning raised his face, and his eyes were full of innocent looks.

After all, sticking your hand in sticky stool is not a beautiful experience for a long time......

"Is it possible that this is the brain fluid of a phase-level zombie that you can't absorb as a pawn-level zombie?"

Xiao Ran opened his mouth and said one of the most convincing inferences.

"But the two zombies I absorbed before are very ordinary zombies, and they are not pawn-level zombies......"

Zhang Ning scratched his head with his clean left hand, looking puzzled.

"Is it possible that you couldn't absorb anything else because you had absorbed that purple bone marrow fluid before?"

Lu Yu touched his nose and reasoned along Xiao Ran's train of thought.

"Possibly...... Shall I try it tomorrow? ”

Zhang Ning withdrew his right hand, looked at the black slime dripping down on it, and felt a wave of nausea in his heart, and wiped it on the zombie in disgust.

"And what about this headless corpse?"

Shao Xiuqi, who had been pale on the side, seemed to have adapted to the situation in front of her at this time, and spoke.

"If you don't have a head, you should be dead, and it's easy to stink upstairs, so throw it downstairs, Xiao Xiao ......"

Lu Yu dragged a long voice, with a mean look on Lu Peel's skin, and looked at the sturdy girl.

"Obey, Boss Lu ......"
