[Decisive and unwavering in killing + Beast Taming + Global Evolution + No Rebirth + No Female Lead + Strong Protagonists]

The end of the world is coming, human civilization collapses, species evolve wildly, and ferocious mutant beasts and zombies are spread all over the world.

Shen Nian Ze awakened the system.

I thought I could punch the zombies in Nanshan and kick the strange beasts in the North Sea, but it turns out my ability is animal evolution and understanding animal language?

While the survivors are struggling to survive among zombies and mutants, Shen Nian Ze owns a dilapidated zoo.

So, the style of painting changed completely:

Shen Nian Ze originally wanted to develop in a low-key manner, but his employees were more enthusiastic than each other, feeding him like crazy and forcing him to stand on the top of the world.

The Siberian tiger's small mouth shattered the tank-sized mutant with a claw and threw a crystal core at it: "Upgrade quickly."

The lion Ah Shi lazily lay at the gate of the base, facing the foreign enemies with a cold look: "We are just a handful of people, who are you looking down on?"

Black Panther Heizi appeared silently on the wall: "All threats within three kilometers have been eliminated."

The giant python Dabai slowly tightened its body, using it to create a safe zone: "Don't get close to me... uh, don't get close to my boss."

Brown bear Panda came over with a bucket of mutant honey: "Boss! Come and have some!"

Shen Nianze: "No, everyone, who is the breeder?"

I wanted to conquer the apocalypse with my pets, but ended up being raised to be the biggest gigolo in the apocalypse.

This is a lighthearted (?) story about the beast kings who are madly competing with each other, desperately trying to feed their precious humans, and by the way, bringing about the end of the world.

I want to write a book. First, I need an interesting and handsome protagonist to connect with the reader. Then, one or two beautiful, lovely girls... maybe three or four would be nice too. With a boy and a girl, it's only natural to add some romance, some ambiguity, some heart-throbs, a layer of milk and honey, a touch of bitterness and astringency, all mixed together... It looks delicious. Then, add a flirty narrator and set it up as a system. Finally, to make the book taste even better, I need to add more sugar. I open the sugar jar, and then, with a slip of my hand, I pour the whole thing in... Damn, isn't that too sweet? I hurriedly pour in some more "Book of Songs," some Shura scenes, some life philosophy... Finally, this is the book... I think it tastes pretty good.

[All-people job transfer + summoning flow + invincibility + cool and refreshing + funny + entries + no emotional drama]

Ten thousand races invaded, and everyone changed their jobs.

Every human being has an opportunity to awaken his or her profession, pursue the pinnacle, and defend the country.

Lin Ze changed his job and became an S-class demon summoner, but was laughed at by everyone.

Because contracting a demon consumes one's own lifespan, it is basically useless.

But Lin Ze smiled without saying anything, because he had awakened a system that could increase his lifespan by killing.

Kill a chicken and your lifespan increases by 1 day.

Kill a Skaven soldier and increase your lifespan by 10 days.

After killing a Fire Spider, lifespan increases by 12,000 days.

So, there are all kinds of awesome demons for you to choose from!

Consume 10 years of life, summon hellhounds, and launch a shadow raid!

Consume 100 years of your lifespan, summon the Flame Demon General, and burn everything!

Consume 150 years of your life to summon the Succubus Queen, who is so charming that she captivates everyone!

I am a legion by myself!

Not only that, completing system tasks can also draw various entries and apply them to yourself and the devil:

I won the soul link, and it just reached level 5 with attributes exceeding ten thousand!

If you draw the lucky number, you will be immune to all negative states!

If you draw the magic of heaven and earth, your size and ability will be expanded 100 times!

Soon after, the myriad races that had been eyeing the human race covetously led their armies to invade.

Alien lord: "Hehehe, I have been planning this for a hundred years, and all humans must die!"

Alien soldier: "Report to the king, our army has collapsed, and the enemy looks more like a villain than us!"

Giant dragons roared in the sky, golden behemoths ran across the earth, giant Krakens stirred up thousands of meters of sea water, and the ancient hundred-eyed giant slowly poked its mountain-like head out of the cave.

Fantasy creatures are rampant on the continent.

Lin Yan came to this vast alien continent, looked at the weak magicians all over the world, and then looked at the giant dragon next to him that was knocked unconscious by him accidentally, and felt a little hesitant.

Why do I feel like I'm different from everyone else? I'm a little bit stronger...

In his previous life, Zhang Beixing died young due to health reasons, but was reborn back to his college days.

Looking at this young, healthy but weak body, he decided to exercise hard and strengthen his body starting today.

[Question: I want to improve my physique and become stronger. What should I do?]

Zhang Beixing went online for help, and the system happened to appear. As long as he listened to advice and completed other people's suggestions, he could gain ability points and become infinitely stronger.

"Running slowly? Then carry some weights! Carrying 50 kilograms of weight and running ten kilometers every day will definitely make you as light as a swallow."

"Lack of jumping ability? That's because you didn't step your left foot on your right foot. If you train like this, you can fly..."

"Want to learn some weapons for self-defense? Come on, who touches controlled knives these days? Just practice chopping tree stumps with a wooden sword. Swing the sword ten thousand times a day, and when you've mastered it, you can injure people with your sword energy."

"Want to learn some kung fu? Who still practices traditional self-defense these days? Times have changed! Why not try to deduce the 'Flowing Water Shattering Rock Palm' and the 'Origin of Qi Body'..."

“…”

As one outrageous suggestion after another was put forward by stupid netizens.

Several years later, Zhang Beixing was interviewed and asked how he became a 'superman'.

He smiled slightly: "Nothing, I just listen to advice"

Netizen: "??? We are just joking, are you serious?"
