It's the end of the world, what's the use of giving me the Cao Ze system?

“Bite!????”

Chen Kang understood subconsciously.

It turned out that it wasn't the system that was discovered, but rather that the mutant zombie's "love was too passionate."

In other words.

Her original intention was to kiss the target zombie because of the effect of Cupid's arrow.

As a result, he used too much force and bit the other person's head to pieces.

"Fuck! Is this even possible!?"

"Just kiss, why do you have to bite?"

Chen Kang was both helpless and speechless.

He never dreamed of it.

There is actually such a bizarre explanation.

But after calming down a little, he seemed to have figured things out.

Because there are many such situations in the animal kingdom.

When animals mate, they often hurt each other because they are "too passionate".

Incidents of death and injury from biting occur frequently.

The most typical ones are the black widow spider and the praying mantis.

These two will eat their opposite sex companions directly during mating...

The slightly better ones are the male sea otters, who will bite the female hard during mating.

That's right, bite hard.

Therefore, they often bite off the female's flesh directly.

Although it will not cause death directly, it may cause symptoms such as infection later, which may also result in death...

……

So back to the present.

The behavior of the mutant zombies was likely similar to that of sea otters, and they were a bit perverted.

It is in line with the laws of nature.

But the problem is...

"This is fucking zombies, the apocalypse, what's with the natural world?"

It's totally unreasonable, okay?

Chen Kang was so angry that he wanted to curse.

Because now, the head of the target zombie that had just been marked was bitten to pieces again.

It took a little longer than before, about 17 seconds.

But this still greatly reduced his control time.

"Damn it!"

Chen Kang raised his eyebrows.

It seems that the only option is to do it hard.

10 seconds is 10 seconds, that should be enough!

So he used the same trick again, drew out the bow and arrow again, and attracted the attention of the mutant zombies.

Then immediately activate the stealth skill.

He picked up a crowbar and rushed forward.

"10 seconds."

"9 seconds."

"8 seconds!"

Calculating the time in my mind.

Coming closer.

"5 seconds!"

"You go to hell."

next second.

Chen Kang simply swung the crowbar in his hand.

It hit the mutant zombie's head hard.

There was a muffled sound of "bang".

The mutant zombie seemed to be startled as well.

He actually looked back instinctively.

She obviously felt Chen Kang's presence.

However, due to the powerful capabilities of the system, she could not find Chen Kang's exact location no matter what.

On the other hand, Chen Kang.

I was a little surprised at this time.

Because the mutant zombie's head was not smashed to pieces by him in one blow.

This guy not only has amazing speed and strength, but his defense has also been improved.

Chen Kang didn't dare to stop.

After going around in circles, he attacked again.

Finally, as expected, after three consecutive hits with the crowbar, the mutant zombie's brain finally exploded.

After two twitches, he stopped moving and was dead.

Chen Kang was overjoyed: "Bah, he still died in my hands."

But just when Chen Kang was about to withdraw.

But found out.

There was actually a shiny object wrapped inside the mutant zombie's brain.

It feels like a ruby, emitting a faint light, appearing and disappearing, as if it can breathe.

"Oh! Could it be that this thing has a treasure in its head?"

Chen Kang didn't have time to think about it.

Because there are still many wandering zombies around.

Just because we can't find him doesn't mean we can't hurt him.

If someone is blind and scratches it randomly, he might get scratched.

So he quickly reached in and pulled out the ruby ​​from the brain.

Then he turned around and ran away.

30 seconds of invisibility is just right.

As soon as I ran back into the building, the invisibility was automatically lifted.

"Huh, huh, huh, shit..."

"It's so exciting."

Chen Kang was breathing heavily.

This was the first time he had killed a target alone in a swarm of zombies.

It feels a bit like "taking the head of a general in the midst of thousands of troops".

It’s exciting, really exciting.

But I am afraid, really afraid.

He felt his heart was about to jump into his throat.

I quickly checked my condition and found that my arms and legs were not injured.

There were no scars on the buttocks, chest or back.

Perfect. Completed the game without taking any damage!

…………

So, after taking a short break.

Chen Kang immediately looked at the gem in his hand.

It was still warm in my hand and still glowing faintly.

"Um……."

He didn't understand what the thing was used for, but based on the principle of "not missing the treasure", he took the risk to take it back.

But at this moment, the system suddenly gave a prompt.

【Tip: New illustration unlocked, please click to view.】

A new illustrated book has been unlocked.

Chen Kang didn't think much about it.

I just opened the system casually.

What appeared before his eyes was actually the illustration of this gem.

[Red Brain Stone: A gem found within the brains of mutated zombies. Humans can consume it directly (or orally).]

[Effect of consumption: Permanently enhances the power of the eater (applicable to both enemies and friends).]

[Effects: Can be used to make props, or as "fertilizer for growing plants." Also, grinding it into powder and applying it to wounds can quickly heal injuries.]

[Note: The host has unlocked the "Treasure Atlas". You can enter and view the details after collecting treasures.]

"hiss……."

Chen Kang's pupils trembled.

I didn't expect that I would find such a treasure. This thing actually has so many effects.

Eating it directly can permanently increase your strength.

Something like "attribute points" in the game.

As for the suffixes that are common to both friends and foes…

It may not have seemed like a big deal before, but now it seems like another hint.

In other words.

When fighting, you must not let mutant zombies bite the heads of other mutant zombies.

Otherwise, this thing would be eaten by the mutated zombies themselves.

Regardless of whether it will increase their strength, if they are eaten by them, it will be equivalent to losing an important treasure.

"Um……."

So Chen Kang must keep this detail in mind.

Then he pondered the details of using the gems.

Make props and use them as fertilizer.

These functions seem to be unavailable at the moment.

Because making props obviously requires a recipe, which he doesn't have.
