Tang Zheng walked quickly to the window welded with steel plates, and looked through the gap between the steel plates, several huge bloodthirsty eyes were hovering in the air with open wings, preparing to launch a second wave of attacks on Tang Zheng and the house they were in.

Tang Zheng touched his chin, and then he called up the information about himself in his mind, and after taking a general look at the values that represented the various functions of his body, Tang Zheng was faintly planning a bit of a risky plan in his heart.

After Tang Zheng obtained and learned the basic mastery skills, he could most intuitively understand the state of his body's various functions.

He focused on the bottom bar, which represented the level.

The original level value was 2 (39%/100%), but now it has become 2 (75%/100%).

Tang Zheng knew that it was due to the experience he had gained after killing the three goblins.

The number before the level value represents the current level, and the two percentages in parentheses after it represent how much experience is left until the next level.

At this time, Tang Zheng's experience value had reached seventy-five percent, which meant that as long as he killed a few more monsters and made up the seventy-five percent to one hundred, then his level would be increased once.

And after the level is raised, Tang Zheng will get a big improvement no matter which of his own values.

In the era of the end of the law, the rank directly represents a person's strength, and the higher the level, the stronger the strength.

In the same way, the stronger the person, the easier it is to survive in the era of the end of the law.

Tang Zheng returned to the bedroom, Yang Yueying, who was lying on the bed, was already asleep, and the wound on her back had stopped bleeding.

After Tang Zheng glanced at her a few times, he picked up the withered butterfly knife on the side and walked out of the bedroom again.

He took a knife and laboriously removed the steel plate welded on a window.

As soon as the steel plate fell off, a sharp and piercing scream rushed out of the window, and with the sound of a wooden board cracking, a large bloodthirsty eye broke through the window that had lost the steel plate defense and rushed in.

Tang Zheng's eyes froze, and then he raised his hand and slashed at the head of the bloodthirsty eyes that had just pounced in.

"Poof!"

A dull voice sounded in a bloody light, and the hideous head of the bloodthirsty eyes the size of a basketball was slashed to the ground by Tang Zheng.

Grade: 2 (92%/100%).

As the bloodthirsty head fell, the experience value in Tang Zheng's mind quickly changed.

He raised his eyebrows happily, it seems that killing a bloodthirsty eye can provide him with a lot of experience points at present, at this rate, as long as Tang Zheng kills the bloodthirsty eye again, then his level will be improved.

Tang Zheng licked his lips excitedly, then he clenched the withered butterfly knife in his hand, and looked at the window that had become empty, waiting with anticipation for the next attack of the bloodthirsty eyes.

"Eagle!"

With another scream, a bloodthirsty eye rushed in from the window in Tang Zheng's happy gaze.

Tang Zheng excitedly picked up the withered butterfly knife and pounced on the bloodthirsty eyes that had just rushed into the house.

With a short but fierce fight, Tang Zheng's hand fell, and the second bloodthirsty eye also fell in a pool of blood.

At the same time, the mechanical voice of the Apocalypse System without the slightest emotion sounded in Tang Zheng's mind: "Congratulations on the upgrade!" Current Host Level: 3 (0%/100%). ”

After the sound of the system sounded, Tang Zheng clearly felt that some kind of change had occurred in his body.

Tang Zheng knew that this was the feeling that after his level was raised, all the functions of his body were strengthened.

Tang Zheng clenched his fists, he felt that his strength was stronger than just now at this time, and his body could also clearly feel lighter, and the feeling of powerlessness caused by the loss of force before also disappeared without a trace at this moment.

After the upgrade, Tang Zheng felt that his current state had reached its peak at this time.

He knew that this was the benefit of the Apocalypse system to these survivors.

As long as the survivor can be upgraded before death, then even if the injury is severe, the next second after the level is raised, the survivor will be unharmed and jump up and down again.

Tang Zheng looked at his arm happily, and then he suddenly thought of Yang Yueying, who was seriously injured because of himself.

If Yang Yueying's level is also raised, then she will be like Tang Zheng now, clearing all kinds of negative states on her body and adjusting her body's various functions to the peak state.

But Yang Yueying is very seriously injured now, and Tang Zheng doesn't know how many monsters she needs to kill to get an upgrade, so it will be very dangerous if she is pulled out now and let her fight those monsters, and if she doesn't get it, she will lose her life, this is not a joke.

A few more bloodthirsty eyes hovered over the city, focusing their attention on Tang Zheng and the room they were in.

Suddenly, Tang Zheng snapped his fingers excitedly.

"There's a way!"

At this time, Yang Yueying felt very uncomfortable, and she didn't know how long she hadn't experienced the drunken taste of dizziness.

And she still feels very nauseous and wants to throw up, but the injury on her back does not allow her to get up, so she has been lying in bed and fighting against the adverse reactions in her body.

"Where did the damn stinky boy go, Sister Loss saved him, this sister is uncomfortable and can't see others, damn wait for my sister to be well, I must teach him a good lesson!"

Yang Yueying lay on the bed and gritted her teeth, thinking about how to fix Tang Zheng after her injury healed.

At this time, the bedroom door was suddenly kicked open, and then Tang Zheng hurriedly ran in with a bloodthirsty eye covered in blood and dying.

Yang Yueying was startled by Tang Zheng's kicking on the door, she thought it was a monster attacking her, but before she could make a move, Tang Zheng's panting voice reached her ears.

"Grab those claws of yours and kill them!"

Yang Yueying was very strange: "You are about to kill it, why do you want me to make up the knife." ”

Tang Zheng threw the dying bloodthirsty eyes on the floor in front of Yang Yueying, he wiped the sweat on his head, and scolded in a low voice, "It's really fucking heavy", and said to Yang Yueying in a somewhat hurried tone: "I don't have time to explain so much to you, I won't hurt you, you listen to me and kill it first, and I'll get you a few later." ”

After finishing speaking, Tang Zheng hurriedly ran out again.

Yang Yueying looked inexplicable, what is this kid going to do?

Although she didn't understand Tang Zheng's approach now, she still took out the pair of sharp claws in her pocket suspiciously, and then endured the sharp pain behind her back and slit the throat of the bloodthirsty eyes.

"Complete Achievement: First Blood."

"Get Rewarded: Turn on Host Basics."

Just after Yang Yueying killed the dying bloodthirsty eyes, the mechanical voice of the Apocalypse System without the slightest emotion suddenly sounded in her mind.

After the voice of the Apocalypse System ended, Yang Yueying looked at the pages of information that suddenly appeared in her mind with a stunned expression.

After reading it, she faintly sensed in her heart what Tang Zheng wanted to do.

"This stinky boy..."

The corners of Yang Yueying's mouth lifted slightly, revealing a very good-looking smile, and then the smile disappeared quickly like a flash in the pan, replaced by a hateful expression.

She gritted her teeth and muttered in a low voice: "Damn stinky boy, if you don't tell me in advance if you have such a good thing, you have to pull out his skin when my sister is well!" ”

Just as he was scolding, Tang Zheng walked in with a bloodthirsty eye that was fluttering with a pair of weak wings.

He threw his dying bloodthirsty eyes on the ground, then sat down on the ground and gasped for air.

"... It's so heavy... I'm exhausted! ”

Bloodthirsty Eyes weighed about a hundred pounds, even if Tang Zheng had just upgraded his physical strength, it was still a little difficult to run around with something of more than a hundred pounds, not to mention that he had to fight with Bloodthirsty Eyes and capture it alive.

Now capturing two bloodthirsty eyes alive is Tang Zheng's limit, so after letting go of this bloodthirsty eye, Tang Zheng took advantage of the fact that the next bloodthirsty eye had not yet launched an attack on him, and hurriedly welded the window that he had opened before with a steel plate again.

After Tang Zheng gasped for a while, he stood up, walked to the shopping cart, took out a bottle of mineral water, and drank it in a big gulp.

After drinking the mineral water, his eyes looked at Yang Yueying who was lying on the bed.

"You probably already have your numerical information in your head by now."

Yang Yueying nodded: "Yes." ”

Tang Zheng smiled: "Then can you tell me the value of the information of your level." ”

After Yang Yueying glanced at the information, she replied to Tang Zheng: "Level: 1 (99%\/100%)." ”

Tang Zheng nodded, then he kicked the bloodthirsty eyes that were fluttering on the ground, turned his head and said to Yang Yueying: "Kill it, your injuries should be almost healed." ”

Yang Yueying raised her eyebrows, and then, without saying a word, she poked out four blood holes in the bloodthirsty eyes that were about to die with one claw.

The bloodthirsty eyes quickly lost their vitality after letting out a wail, and at the same time, the originally hideous wound on Yang Yueying's back suddenly disappeared without a trace at this moment, not even a scar was left, only a string of cotton threads sewn by Tang Zheng before was left lying quietly on Yang Yueying's smooth and white back.

Seeing the changes in Yang Yueying's body, Tang Zheng was finally able to put down the big stone that was pressing in his heart.

Yang Yueying is finally fine.

Just when Tang Zheng breathed a sigh of relief, Yang Yueying, whose body had fully recovered, suddenly jumped up from the bed with difficulty, and then scratched four deep marks on the wall behind Tang Zheng with one claw.

And the blade of her claws that flipped with cold light was only less than a centimeter away from Tang Zheng's neck at this time.
