What Su Ze had to do with Liu Ren was very simple.

Brush the level!

According to Su Ze's observations, the abilities that each person develops as a result of upgrading often have a certain correlation.

A typical example: Zhou Li.

He was a track and field athlete before the end of the day, so it can be said that speed was originally a strength.

After the apocalypse, he developed the ability to "accelerate", "like the wind", which tends to be agile and speed-enhanced.

And himself, because his mental power is far beyond ordinary people, so both abilities are highly related to spiritual power.

Now to fight against the Iron Wolves, the most critical first step must be reconnaissance.

This Liu Ren's first ability is "Eagle Eye", which is exactly what he needs, so his other abilities are also likely to be in this direction.

What Su Ze is looking forward to is what this Liu Ren's second ability will look like.

So he wants to take Liu Ren to quickly rise to level 20.

It's like playing online games with a large number with a small number of upgrades.

Finally, let Su Ze find a group of zombies.

In order to facilitate Liu Ren's experience, he wanted to try to release a "spiritual impact" on zombies this time.

Su Ze approached the zombie group.

"Mental Shock"

"Mental Shock"

“......”

One by one, the zombies fell as he unleashed them.

Su Ze was happy in his heart, this trick also works for zombies!

Wouldn't it be much more convenient to bring people to level up in the future?

In the last days, Su Ze has always been worried about the important people around him, and the idea of taking them to level up has been around for a long time.

After all, at the most critical time, it is most reliable to let them have the strength to protect themselves.

Su Ze had more than 30 mental shocks before all the zombies fainted to the ground.

Originally, the zombie group found Su Ze, and when they were roaring and rushing towards them, they fell to the ground one by one, and none of them succeeded in getting close.

Su Ze estimated that the maximum distance at which his Spiritual Impact ability could be released was almost 10 meters.

His flame ability is about the same distance.

"Go and get to know these zombies." Su Ze said to Liu Ren behind him.

Liu Ren recovered from the shock at this time, and he hurriedly passed.

He took a steel pipe with a sharpened head and stabbed through the zombies' heads one by one.

At the same time, he couldn't help but be shocked again, this group of zombies with weak legs in his opinion, was so defenseless in Su Ze's hands.

Feeling the improvement of experience points, Liu Ren killed harder and harder.

There are many variants of speed zombies and ironclad zombies in this group of zombies, and the experience provided is still good.

After Liu Ren killed more than 20 people, he suddenly got sick.

"I've reached level 17!"

Liu Ren said in surprise.

"Go on."

Su Ze nodded indifferently.

"Roar..."

At this time, the mutation suddenly appeared, and the few zombies on the ground that were not dead suddenly roared.

One of the zombies was at Liu Ren's feet, and it opened its mouth to bite his leg!

Liu Ren was also shocked at first, but after all, he was a survivor who had dealt with zombies for half a year at the end of the day.

He's also quick to react.

Immediately dodge, insert.

The zombie died.

At the same time, several other zombies also began to get up.

Seeing this, Su Ze was inevitably a little surprised in his heart.

When he unleashed a "spiritual shock" on humans before, if there was no external stimulation, those people would have been in a coma for a long, long time.

However, it was unexpectedly that the zombie woke up so quickly this time today.

But an accident is an accident, it's a big deal to faint again.

Su Ze quickly put a few more "mental shocks".

The zombies fell weakly again.

For him, there is almost no limit to the number of times "Psychic Shock" can be used.

He had just used it more than 30 times in a row, and he didn't feel any discomfort.

Seeing that the zombie fell to the ground again, Liu Ren breathed a sigh of relief, and he secretly said that Su Ze was indeed a very reliable powerhouse.

This kind of method of stunning zombies is simply unheard of for him.

"Let's go."

Su Ze saw that Liu Ren had finished killing all the zombies, so he spoke.

"Yes."

Liu Ren put away the steel pipe and followed Su Ze.

They walked around, and only found some scattered zombies, which were far from enough for Liu Ren to be promoted to level 20.

Su Ze had already figured out the rules of upgrading experience.

According to his calculations, level 17 to level 20 only takes about 840 experience.

And Su Ze himself, if he wants to upgrade from level 21 to level 30 to get the third ability.

A minimum of 4320 experience is required.

If you want to kill ordinary zombies, you have to kill more than 4,000 of them.

There are also more than 800 variants that provide 5 experience.

I'm afraid it won't be completed in a day or two.

This is also the reason why Su Ze himself is not in a hurry to kill zombies.

Since it is almost impossible to upgrade yourself, it is better to help your subordinates improve their strength, but they can increase their vitality even more.

Of course, if the kind of ironclad scavenger who provides 3000 experience points reappears, he will definitely not refuse.

If he can't find the zombies, Su Ze is not in a hurry, he has some conjectures in his heart, and he will verify it today.

He went back to the pile of zombies he had just killed.

It was found that several zombies had already eaten the corpses.

There are 7 or 8 zombies, all of which are gecko-type.

The appearance of the gecko type is no longer the same as that of ordinary zombies.

At least the skin on his body is not as tattered as ordinary zombies.

They appear to have muscular limbs, gray bodies, and huge mouths that take up a large part of their faces, revealing frightening sharp teeth as they bite through corpses.

This is the gecko type mutant zombie, which looks like some kind of infernal creature described in myths and legends.

When Su Ze saw this scene, he said in his heart, sure enough, this is the case.

He had speculated that zombie corpses would attract other zombies, and zombies seemed to have an obsession with eating the corpses of their own kind.

The first time he met the ironclad scavenger was probably to eat the corpses of the zombies near his house.

"Go and kill these."

After Su Ze casually stunned these gecko types with a few mental shocks, he motioned for Liu Ren to go over and mend the knife.

"Yes."

Liu Ren took his steel pipe, walked into the pile of zombie corpses, and stabbed it several times in a row.

His movements can be regarded as steady and ruthless, after all, as a level 17 person, he already has 24 attribute points that can be freely distributed in strength, speed and endurance.

Although he is not on the same level as a ruthless person like Su Ze, he is definitely much stronger than ordinary people.

Liu Ren's stab accurately pierced the gecko-shaped heart with each blow.

Su Ze said that the weakness of the gecko type is in the heart, which Liu Ren kept in mind.

Gecko types provide 25 XP each, for a total of 8 geckos.

+200 XP

Liu Ren confirmed the experience income on his system panel, and he couldn't help but be overjoyed in his heart.

It takes 260 experience to get from level 17 to level 18, and in just a moment, he has completed most of it.

With his previous experience, he only needed a dozen points of experience to be at level 18.

The speed of this upgrade was simply unimaginable for him.

didn't wait long for Liu Ren to be happy.

"Roar!!"

A huge monster with four claws attached to the wall of the building roared in anger.

It's its classic way of playing.

That's right, a scavenger!

Liu Ren was attracted by this roar, and when he looked up, it was a real monster, huge and terrifying, and it was almost completely indistinguishable from the human form.

The way it opened its huge mouth and roared frightened Liu Ren to retreat again and again, and he hurriedly hid behind Su Ze.

Su Ze remained motionless in place, and Su Ze's figure was like a towering mountain in Liu Ren's eyes, giving him a great sense of security.

When the scavenger spotted the two, he immediately used his hands and feet to charge at them.

Su Ze was very laid-back, and he even turned on his dynamic vision to observe this scavenger.

In his eyes, everything began to slow down.

He saw the fluidity of the scavenger's body on the run, the coordination of the muscles taking turns exerting force, fully cooperating with each other.

In addition, the scavenger's four palms have layers of protrusions, and every time its claws land on the wall, this structure creates a great absorbing force.

The scavengers also walked on the walls.

These really surprised Su Ze.

He couldn't help but wonder, could this mutation be some kind of evolution of zombies?

And humans can also upgrade their experience by killing zombies, is this also a kind of evolution of humans?

Could it be that the purpose of the end of the world is to allow humanity to evolve?

Seeing that the scavenger was about to approach him, Su Ze temporarily put aside these questions and didn't want to.

"Mental Shock"

The scavenger suddenly fell to the ground with a weak body.

A monster of huge size suddenly fell without warning, and I have to say that this scene is extremely dramatic.

It was as if it had suddenly suffered some huge blow, and it fell to the ground and could not move.

Su Ze was satisfied, because the psychic shock also worked against monsters like scavengers.

It seems that these monsters have only developed their bodies, and their spirits have not grown at all, Su Ze thought to himself.

"The weakness is still the heart, this blood is thick, poke it a few more times."

Su Ze said.

"Yes!"

Liu Ren said excitedly, he simply didn't know how to express his excitement.

Although he hadn't killed a scavenger, he had heard the conversation between Su Ze and Zhu Lan at that time.

This monster gives you 600 experience!

How many levels can he go up in one go?

He quickly ran over and lifted the steel pipe and stabbed the scavenger in the heart.

Suddenly, his whole body shook.

System Prompt: +600 XP

"I'm level 20!"

Liu Ren was surprised and delighted.

He was called out today and didn't know what Su Ze wanted him to do, but it turned out that he had given himself experience in vain.

This strengthened his mind to follow Su Ze, because not only was it safe to be by his side, but there were also various other benefits.

However, Liu Ren also knew in his heart that Su Ze could take himself to brush up on experience, and it must be his "Eagle Eye" ability that could be used by him.

Liu Ren secretly made up his mind that he must become a more useful person.

Su Ze was not surprised, because it was all in his expectation.

Su Ze asked:

"What abilities have you gained?"
