Ye Hao ran like this, letting his chest have an explosive feeling due to lack of oxygen. The green trees on both sides of the road kept retreating, and Ye Hao didn't stop until he felt that his limbs seemed to be drained of strength, and his brain was a little dizzy due to lack of oxygen. It was about three or four miles away from the town, and a small river flowed by the side of the road, curving into the distance.

Ye Hao fell on the side of the road, looking at the already barren land, the busy figures here in the past have long lost their traces, and the straws of different lengths are scattered in the fields, and the whole land seems to have lost its vitality.

"What's wrong with this world? Is this the real situation of the end times......" Ye Hao's heart roared wildly, the wild run just now made his chest rise and fall, and the sound of junior high school's breathing made his eyes crimson. Yesterday's ordinary life seemed to be still in front of him, he just got up and took a shower, the scene in front of him seemed to be in a dream, Ye Hao really hoped that life would return to the original point after he woke up.

"System?...... Are you still there?system?" Ye Hao called in his head, the system did not react, but projected the electronic map on his retina, and at the same time displayed a line of words at the bottom of the map: July 25, 2068 in the Blue Star Era calendar, there are 71 hours and 20 minutes left before the host completes the task, and it is 28 kilometers away from the target Maple Leaf Town.

Bursting into a foul mouth again, Ye Hao could only stand up helplessly and embark on the road to Maple Leaf Town.

In the desertified land, the sun that had entered the weakening period was emitting a miserable white light, and Ye Hao was sweating profusely, trotting weakly on the lonely road. Not far behind him were several hideous zombies with chapped skin and a foul stench, swaying and whining in their throats.

After nearly 30 hours of trekking, Maple Leaf Town is close at hand. However, Ye Hao was already at the end of his strong crossbow, his chapped lips were peeling, and several small cuts were still oozing blood.

Ye Hao didn't rest for a day and a night, and he decided to rush to Maple Leaf Town as soon as possible while he was still full of strength. Along the way, he bypassed several scattered zombies and hurried to his destination non-stop. After a long time of running, he was now tired and thirsty, the two pieces of chocolate had already been eaten by him, and there was only one piece of chewing gum left in a packet, and he did not dare to eat the last piece of chewing gum. Ye Hao decided that after arriving in Maple Leaf Town, he would be able to find a little food and drinking water with the support of the sugar in that piece of chewing gum. Compared with the crampy stomach, the throat that felt like it was about to catch fire was what made Ye Hao the most painful. Since coming to the end of the world, Ye Hao has not drunk a drop of water, but he has passed several small rivers along the way, but the decaying animal and plant corpses that appear by the river from time to time make him dare not quote any drop of water.

In these 30 hours, Ye Hao wanted to give up more than once, especially after the second half of his physical fitness reached the limit, and he lacked food and water supplements, Ye Hao really wanted to lie on the ground and let the zombies following behind him divide his body. relied on his strong will to survive the difficult period again and again, but now, Ye Hao couldn't hold on anymore, the chaotic brain, the crampy stomach, the throat that was about to catch fire, the heavy steps, all of which made him want to die.

After tripping over an iron plate that fell on the road, he fell to the ground and couldn't get up again, Ye Hao was shrouded in despair.

"The host task is complete, do you want to receive the reward?" Just as Ye Hao was lying on the ground waiting for death, the voice of the system sounded. After waiting on the ground for almost ten seconds, Ye Hao felt that his soul slowly returned to his body. Ye Hao stared at the system control panel mapped on the retina, and finally reacted, shouting in his heart: "Receive!"

"Drop, the host has successfully received the task reward......"

"Reward 1: The host gains the skill - preemptively. ”

"Reward 2: The host obtains a first-class genetic potion. ”

"Reward three: The host gets a chance to return to the real world for 72 hours. ”

"Does the host return to the real world?"

After being stunned for a few seconds, Ye Hao came to his senses, looking at the few zombies that were already less than ten meters, he shouted hoarsely in his throat: "Return, return ......"

Immediately after a burst of dizziness, Ye Hao opened his eyes tremblingly, and what caught his eyes was the colorless water droplets that were constantly spraying in the shower.

Feeling the moisture of the water flowing through his skin, Ye Hao opened his chapped lips and gulped down the warm liquid.

It took two or three minutes before Ye Hao stopped drinking and struggled to sit up.

Quietly feeling the spray of the shower, Ye Hao thought silently: If you have to return to the end of the world after 72 hours, you must make some preparations. The environment of the last days is too harsh, the first thing to consider is survival, to survive you need food and drinking water, and secondly, to deal with zombies, you need weapons. For now, with the necessities and weapons for survival, you should be able to protect yourself.

Thinking of self-preservation, Ye Hao suddenly remembered that he was in a hurry to return to the real world just now, and he hadn't seen the system's task rewards yet.

As soon as the brain moves, the system panel is projected onto the retina:

Name: Hao Ye

Gender: Male

Age: 25

Genetic Grade: Grade Zero

Skill: Language proficiency (the host is able to quickly grasp and use all human languages it comes into contact with)

Absolute Static (the host makes the opponent's time and space stand still for 1 second when attacking or defending, and can be used 3 times in 24 hours)

Ye Hao was very happy to see the two extra skills on the system panel, and it seemed that the effort was still rewarded. But why is the level still level zero?Wait, it seems that there is some first-level genetic elixir, Ye Hao searched all over his body and couldn't find it.

"It's not on the body, is it ......" Ye Hao let his consciousness perceive the dragon-shaped tattoo, and sure enough, in that gray space, there was a bottle of light red potion.

Ye Hao took out the potion through perception, hesitated for a while, or opened the bottle cap and drank it in one gulp.

After a while, he felt a burst of unbearable soreness all over his body, and Ye Hao gritted his teeth and insisted. After ten difficult minutes in pain, I felt that my body suddenly lightened, and my whole body was cool, and at the same time, there was an extra layer of sour black dirt on my skin.

Ye Hao summoned the system panel again, and sure enough, the rest of the panel had not changed, but the gene level had become level 1.

Ye Hao clenched his fists, feeling that the lost strength had returned to his body, and it had improved to a certain extent. However, it was followed by a thunderous sound in the belly.

"Hehe, I'm starving, I'm going out for a big meal", Ye Hao hurriedly took a shower, changed into clean clothes, and walked out of the hotel.

Ye Hao's family is not very wealthy, and the tuition fee in the United States is a large expense, and his living expenses are earned by his usual part-time job. This time when he returned to his hometown, his parents gave him another $1,000, and now he has a total of less than 10,000 yuan.

After experiencing the dying struggle of the last days, he was already open-minded and didn't care about money, but he didn't dare to spend it indiscriminately. Ye Hao found a clean home-cooked restaurant near the hotel, asked for seven or eight meat dishes, and began to gobble down the rice.

It may be that after becoming a first-level gene body, the consumption increases, or it may be that the 30 hours of desperate running around in the last days caused Ye Hao's appetite to be great. Anyway, 20 minutes later, when he looked up with a full burp, he saw the stunned faces of everyone in the restaurant. Smiling embarrassedly, Ye Hao quickly got up to check out, less than 300 yuan.

After paying the money and leaving the hotel in a chic manner, he strolled through the bustling streets of the magic capital, lit a cigarette comfortably, Ye Hao found a clean place to sit down, leaned against the tree behind him and closed his eyes.

"System?" After waiting for a while and not responding, Ye Hao asked again in his mind: "Can I bring things from the real world to the end of the world?"

"The host can teleport non-living beings between the two worlds through the system space. ”

Oh, that is to say, there is no problem in transporting supplies, which is good news for Ye Hao.

"Does food spoil if you put it in the space?"

"Time stands still in space. ”

"What do you mean?"

"The system is concerned about the host's IQ, and time stands still means that all rules in space are frozen. ”

Ye Hao didn't bother to pay attention to the sarcasm of the system, and opened his eyes excitedly, it seemed that the items were put in and taken out.

He remembered that the system space expanded as his level increased. Ye Hao immediately sensed the system space, and in his perception, the original 1 cubic meter space expanded many times.

Ye Hao suppressed his excitement and asked again, "How is the size of the system space calculated?"

"The size of the system space is determined by the genetic hierarchy of the host, which can be simply understood as a cube with 3 to the nth power as the side length. ”

"What does this n mean?"

"n is the level of the host. ”

Ye Hao immediately understood the meaning of the system, when his level was level zero, the side length of the space was 3 to the power of 0, that is, 1. When his level is level 1, the side length of the space is 3 to the 1st power. And so on.

That is, the system space is now a cube with 3 sides and a size of 27 cubic meters.

"I'll take care of it, when Lao Tzu is promoted to the tenth level of the gene body, it can't fit a city. Wiping the saliva from his mouth, Ye Hao interrupted his reverie, the most important task now is to purchase daily necessities.

Ye Hao remembered a serious question, "System, will I bring the virus of the end times to the real world?"

"No, when the host places an item in the system space, the system will automatically scan and kill any life that enters without permission. ”

Ye Hao was relieved, after all, viruses also belong to living organisms, "By the way, so living beings with your permission can enter the system space?"

"The host doesn't have enough permissions to answer the host question. ”

"Damn, you're a scoundrel again. Faced with the system of pretending to be dead again, Ye Hao had no choice but to give up.
