Gently stroked his chest and took a deep breath for more than ten seconds before Song Nan could stabilize his breathing and stop panicking.

If you are not afraid in an environment surrounded by zombies just now, it is impossible, Song Nan felt that his heart was about to jump out at that moment, but he didn't expect that the idea that space was a way out before really became a reality.

But it's too dangerous!

Song Nan didn't expect that the originally empty yard would be crowded with zombies all at once. She just glanced at it, at least thirty zombies! Song Nan was a little distressed, she had just been in the space for about ten minutes, and three or four minutes had passed outside, how could so many zombies suddenly gather?

Could it be that someone from outside has brought it in? Song Nan was in the air, if this is the case, the target of those people must also be that the warehouse has not run away!

Song Nan was a little anxious in an instant, so how long would she have to stay in the space before these zombies could disperse, or if the zombies ran to the people who attracted zombies outside, so that she could get out of the danger just now!

Squatting by the river with a frown for a full minute, Song Nan was a thief, she was really unwilling to give up the electronic equipment that was about to arrive to others!

Holding the dagger in his hand, Song Nan took a deep breath and flashed out of the space.

This time Song Nan had experience, and when his eyes hadn't seen the outside world clearly, his spiritual power had already been released, and in an instant, the situation in the entire yard, including the warehouse, was clearly reflected in Song Nan's mind, and the position where she appeared was close to the back of a zombie, and the smell on Song Nan's body stimulated the zombie at the first time, and he immediately roared angrily, turned to Song Nan and was about to bite down.

Song Nan's spiritual power is faster, before the zombie can turn around, the dagger in Song Nan's hand has been slashed horizontally, although the connection between the zombie's head and the cervical vertebrae has been cut, but it has not been directly cut off, the zombie's head was hammered down instantly, spurting out a large amount of black blood and bloody yellow **.

The zombies next to him had already been pouring towards Song Nan, and Song Nan didn't have time to dig out the crystal nucleus in the zombie's head. I had to grab the corner of the zombie's black clothes with one hand and take it into the space.

The place where Song Nan entered the space was the river downstream, and the position below the bathroom was almost close to the barrier. Throwing the zombie on the ground, Song Nan pouted, hurriedly dug up the zombie's head, and after digging out the crystal nucleus from the zombie's head, he patted it on the shoulder without hesitation, and the zombie disappeared from the space and was thrown out of the space by Song Nan.

Using the method just now, the crystal nucleus was cleaned, and Song Nan found that this was actually a first-order red nucleus, which was a fire-based crystal nucleus. Song Nan did not use the crystal nucleus to dissolve the crystal nucleus in the well water again and drink it, but in the open space on the side of the "kitchen", he released a table, found six boxes from the warehouse, and engraved a "red" character with a dagger on the lid of one of the boxes, put the red nucleus in it, and closed the lid.

Most people will not use all the crystal nuclei to absorb them, because after the end of the world, the crystal nucleus is not only necessary for the upgrading of energy sources, but also the universal currency that circulates between various bases. And after the use of human abilities is exhausted, the crystal nucleus is also the best supply, and in times of crisis, it is definitely something that can save your life.

But for Song Nan, she didn't think about this.

The reason why she absorbed the white nucleus and the black nucleus before was because Song Nan wanted to confirm whether the well water could allow her to absorb the crystal nuclei of other departments. Now that it has been confirmed, Song Nan wants to get one of the six crystal nuclei as soon as possible, not only can he introduce the types and methods of crystal nuclei to Tang Shu and others, but also...

Song Nan patted the top of the box, as a person who came from the end of the world, she naturally knew that although the crystal nucleus could help people advance, if she relied too much on the energy of the crystal nucleus, instead of laying a solid foundation for her own strength, even if the level was raised, her own strength was too weak, which might lead to damage to her physique and deterioration of physical fitness. Moreover, this kind of ability built up with crystal nuclei is more like the so-called "empty shelf", the meridians are not wide enough, the energy reserves are not enough, and the actual combat experience is too little, which are the biggest reasons for the death of the so-called "high-level" abilities in battle.

Song Nan now has enough experience to steadily improve his abilities, rather than relying on the energy of the crystal nucleus. What she has to do is to use enough crystal nucleus energy to attack the level barrier in the process of sprinting and ascending, and in normal times, as long as she maintains the absorption state as peaceful as possible.

Moreover, although the crystal nucleus will increase the energy level, generally speaking, the closer to the state of the same order, the better. For example, Tang Shu is a second-order fire-based ability, and he has the best effect when he uses a second-order fire-based crystal nucleus, and a first-order fire-based crystal nucleus will be inferior to him. As for the use of crystal nuclei at the next level, there is a danger of exploding, so this Song Nan will not think about it.

What he has in his hand now is nothing more than a first-order crystal nucleus, and Song Nan can't move his legs when he sees it.

She had more important things to think about.

The moment he went out just now, Song Nan's spiritual power had already firmly investigated the situation in the outside world. To her horror, there was no trace of humans in the warehouse, and even the original number of zombies had not changed. In other words, it wasn't this group of zombies that someone had brought in.

Moreover, these zombies were not scattered in this small courtyard, but concentrated in the place where she appeared and landed.

It's just that they may not be sure if Song Nan will land in the same place every time, so they are not stuck in one place, but they are swaying tightly around, it seems that as long as Song Nan dares to appear, they can all pounce on them.

Song Nan's heart sank, these first-order zombies can stay here so firmly, I'm afraid it is the result of the command of high-order zombies.

So, is it the second-order zombie in the warehouse, or the third-order zombie that hasn't appeared? Song Nan stood in the space, full of fresh fragrance, and the breeze was warm, but it couldn't dissipate the worries in her heart. If it was really that third-order zombie, there should have been initial wisdom, and since he had already sent his first-order zombies to surround it, he wouldn't give up easily!

How would she get out of the zombie encirclement, and how would she get into the warehouse and collect the equipment she wanted?

An hour has passed in the space, and even if it is outside time, more than ten minutes have passed. And Song Nan was not standing stupidly waiting for inspiration to appear, she found something to do.

All along, it was with the help of her spiritual power that she was able to collect stubble after crop of grain crops in the warehouse. It's just that mature rice needs to be exposed to the sun and dried, and then it can be eaten after being shelled, and she doesn't have agricultural machinery, even if it hurts when the idle egg hurts, she can control her mental power to crush and peel the rice grain by grain, but this is undoubtedly something that a fool will do.

Song Nan is doing this kind of "fool can't do" at the moment. Because Song Nan really couldn't think of a clue, standing in the kitchen, he really felt that he was really stupid, and he didn't even have a clue, and suddenly remembered the rice that had been dried a few days ago, so he simply took out a small bag and began to crush and peel the shell.

It's just that an hour has passed, and Song Nan not only drank three cups of well water to replenish his spiritual power, but also peeled a small bowl of rice grains. The corners of Song Nan's eyes twitched a few times, pushed the bowl, held a rice stalk, and slowly shook it to the bridge, she would never do such a stupid thing again!

But she still didn't know what to do

casually spit out the rice stalk, watching it fall into the water, Song Nan was stunned for a second. Hurriedly ran to the other side of the railing, and stretched out his head to see when the small rice stalk would float in the water. Soon, the rice stalk floated from upstream, and Song Nan's eyes instantly lit up - she can do the same!

The rice stalks float on the water, but they don't float flat, but stand upright in the water and go down the water!

Song Nan clenched her hands tightly, exhaled deeply, her eyes were serious and focused, her right hand slowly pulled away, and a metal strip as thick as an arm appeared from between the palms of her left hand, and after it was stretched to an arm's length, Song Nan's right hand turned to hold the metal strip and continued to work hard to lengthen.

It wasn't until a three-meter-long metal pole was thrown to the ground that Song Nan collapsed all over, gasped for more than half a minute, drank a cup of well water in one gulp, calmed down, and began to pull out the second metal rod.

After pouring another cup of well water, the gold ability in his body quickly recovered. But looking at the two light striped metal rods on the ground, Song Nan suddenly made a difficulty, how could such a thing stand firmly? Simply hold the two metal poles with both hands, and the tails of both poles extend out of a large territory.

"That should be stable." Song Nan said to himself, "Then how can I go up?" If you stand up and let me climb, I'm afraid I'm going to fall, right? It's not a tree... That's right, the tree! Song Nan jumped up excitedly, grabbed the two poles with both hands, and the figure had already flashed into the mountain.

Choosing a big tree, Song Nan helped up the two poles and leaned on the trunk. As for herself, with a raise of her hands, ten wires flew out in an instant, and were firmly wound on a fork at the height of the big tree she selected, her fingertips gathered, and as soon as the wires were tightened and straightened, Song Nan's whole person swung up lightly, and before approaching the fork, she stepped on the trunk of the tree with her feet, and her body fluttered and swayed, and she flipped up flexibly and fell, and Song Nan landed steadily on a branch more than two meters high from the ground.

At the position where the two metal poles are half a meter away from the top, a small platform that can be stepped on is formed, and Song Nan's center of gravity shifted, and the person was already standing on the two metal poles, and then disappeared into the space.

Song Nan stepped on metal stilts and suddenly appeared in the courtyard, as she expected, because she had just reappeared, the third-order zombie had already determined her appearance location, if she left the space as usual this time, she would only be gnawed into minced meat by the zombies in an instant.

At this moment, the metal pole at Song Nan's feet made Song Nan escape from the encirclement of the zombies, but avoided the zombies' pitch-black and hard nails and yellow and black steel teeth in the air.

More than 30 zombies in the small courtyard were crowded at Song Nan's feet, and Song Nan's metal poles were piled up steadily, Song Nan stood in mid-air, his spiritual power had already been spread, and the entire electronics factory was shrouded in an instant, carefully screening every corner!

But in just one minute, Song Nan's eyes lit up, and the smile on the corner of his mouth was sharp and confident-I found you! Stinky guys!

The skinny third-order zombie was hiding in the hall on the first floor of the office building in the front yard, huddled among a group of ordinary zombies, and found that Song Nan appeared three times, but he was not torn to pieces by those incompetent subordinates, and finally couldn't help but snort angrily in the hall, and the zombies in the entire office building trembled because of its roar.

It was for this reason that Song Nan finally found this expert in hiding cats!

Unexpectedly, even a zombie who had just appeared with wisdom knew the truth of "hiding in the city", not hiding in a corner, but squeezing in the middle of its little brother, but making it impossible for humans to find it in the first place. I also know that when dealing with the enemy, I use my younger brothers to carry out wheel warfare, and I just need to sit and wait for safety.

This is the reason why humans are so afraid of zombies!

Although they were originally of the same kind, after mutating and inheriting zombies, they became mortal enemies. The revival of zombie wisdom has made the surviving humans deeply jealous of them, these zombies are getting more and more intelligent with the improvement of their level and ability, if humans can't eliminate them, will they be replaced by the other way?

However, Song Nan didn't have the heart to pay attention to this kind of big thing now, her goal was very simple, kill this third-order zombie first!

The metal pole under his feet was surrounded by zombies and squeezed very steadily, Song Nan raised his left hand, and five metal wires sprang out of his fingertips, converging into a tight strand, and shot towards an elevated highway in the front yard. After the wire was wrapped firmly on the elevated shelf, Song Nan jumped down, and the person had already swung out.

In the drift, Song Nan was also constantly tightening the wire, none of the zombies surging on the ground touched her for half a minute, Song Nan had already crossed the wall and landed on the elevated highway, the next target was the office building!

The third-order skinny zombie obviously found out that Song Nan's target was him, and he was also frightened, roaring again and again, and the zombies in the office building rushed out, Song Nan stood on the elevated road, but there was still some distance from the office building, and she couldn't kill it with one blow!

Before Song Nan hesitated, a group of zombies had already gathered at Song Nan's feet! Moreover, whether it is in the backyard or in the office building, there is still a steady stream of zombies, although the elevated highway is poured reinforced concrete, but under the impact of the huge strength of the zombies, it began to shake significantly!

Song Nan, on the other hand, stared at the direction of the third-order zombie for a moment.
