Liu Xin agreed to go to the northern city through the subway because Liu Xin knew that there must be a backup power supply in the subway, so he could get energy at that time, and the system would not disappear due to the lack of energy. The two came to the subway station soon after, perhaps because of the zombie virus outbreak at night, the door of the subway station has not been opened yet, not to mention the zombies, it is estimated that only the uncle guarding the door is there. Yu Yang's face was not very good, because he didn't pay attention to the time of the end of the world, and guessed that the subway should be safe except for zombies on the platform. Now it seems to be complete nonsense, this subway is completely a safe passage, and there is not much danger at a glance.

Then Liu Xin and the others began to pry the door, and after an hour of hard work, the door was finally completely opened. The subway has long been out of power, it is pitch black, Liu Xin can only barely see the general situation because of the improvement of physical fitness, and Yu Yang has long been unable to see anything. Liu Xin took out two flashlights from his backpack and handed one to Yu Yang, and Yu Yang didn't even say thank you, took the flashlight and retreated to the back, letting Liu Xin go ahead, Liu Xin's anger was also on the verge of going berserk because of this incident.

Liu Xin and Yu Yang first came to the maintenance room and found the start button of the backup power supply. At the same time, Liu Xin got 100 first-class energy through the backup power supply, and Liu Xin didn't dare to absorb more, in case of a power outage, the two of them could only rely on a flashlight to pass the subway, and the sight at that time was definitely not as good as the current electricity. Besides, 100 energy is enough for Liu Xin to deduct the daily consumption, so Liu Xin did not continue to absorb electricity. Liu Xin's absorption of electrical energy was very fast, and Yu Yang didn't notice Liu Xin's small movements at all.

"Squeak, squeak, squeak." Liu Xin and the others, who were still in the maintenance room, suddenly heard a strange sound, and immediately left the maintenance room and went to the front hall outside. Following the track, Liu Xin and Yu Yang saw countless mice, each mouse's eyes were shining, making people feel panicked at a glance, Liu Xin and Yu Yang turned around and prepared to flash. But at this time, Liu Xin felt the coldness of his whole body again, which was a symptom of the re-attack of the zombie virus, and at the same time, his body was uncontrollable, standing in place and trembling, and he had been wrapped around his waist as the tail of the belt, and because he was uncontrollable, he could not continue to tie it around his waist, and slowly hung down. And Yu Yang, who ran a few steps, found that Liu Xin did not keep up, and subconsciously turned his head to look at Liu Xin.

In Yu Yang's eyes, Liu Xin's whole body was trembling, especially his feet, as if they couldn't support Liu Xin's weight, they had begun to bend, and the plush belt that had been tied to his waist was also broken and hung behind him. Yu Yang's eyes flashed with a fierce light, and he turned around and ran towards Liu Xin. When Liu Xin saw Yu Yang turn around, he thought that Yu Yang was ready to pull himself, this was the second time he had saved his life, and he was about to include Yu Yang in the list of friends.

It's a pity that the result was beyond Liu Xin's expectations, after Yu Yang came over, he first grabbed Liu Xin's backpack and violently snatched the backpack over, Liu Xin had no chance to fight back because he was fighting the virus. The backpack was easily snatched away by Yu Yang, and then Yu Yang kicked Liu Xin's lower abdomen, and Liu Xin also fell to the ground because of this kick. "You look like you're crazy, right? Since you're going to die, let's make some more contributions to the living, I'll take your backpack, and your spear and plush belt behind you will leave you to be buried. You can also help me get the attention of the rats so they don't chase me. After speaking, Yu Yang rushed to the exit of the subway station without looking back.

Liu Xin's eyes were full of astonishment, "How can this be, why do you do this, we have no grievances, you still treat me like this." Liu Xin wanted to ask, but unfortunately because of the virus, he couldn't control his body at all, so he could only let out a low roar.

Seeing that the rats were getting closer and closer, Liu Xin slowly calmed down. "If it doesn't go on like this, I will definitely be overwhelmed by the rats, even if I enter the F rank, I can't withstand the bites of so many rats, and being submerged is definitely a dead end." Liu Xin, who was in a hurry, just happened to find a light bulb under his tail. Immediately began to ask the system, "Rhapsody, can I absorb the backup power of the subway station through this bulb that my tail touches?" ”

"The question asked by the host requires 50 level 1 energy, does the host need to answer it?"

", you're still looking for me to ask for money at this time, ask, tell me quickly."

"Ding, deduct 50 points of host level 1 energy, and the current remaining energy is 51 points. The host can absorb energy through contact with any part of the body, and of course the tail can also do it, and the tail comes into contact with the light bulb, which emits light through electrical energy, so the light bulb can be seen as an extension of the energy source. So the host can absorb energy through this bulb. ”

"Okay? Then hurry up and absorb it, absorb it with all your might. ”

After Liu Xin said this, he felt a burst of paralysis, starting from the tail and extending to the whole body, Liu Xin's body also regained control because of the passage of electricity, and the entire subway was once again plunged into darkness.

Because Liu Xin controlled his body again, he was so excited that he didn't even hear the system prompt, picked up the spear and ran outside with all his might, and the rats followed. Because of the double damage of the numbness of the body and the erosion of the virus, Liu Xin's speed is only faster than that of ordinary people running. "Is it that just a little hope has made me despair again? Damn the virus, sooner rather than later, it's just this time. It was dark all around, and Liu Xin could only see a vague shadow. In the face of one of the shadows, he subconsciously used the detection technique, Name: Mutant Rat Level: Unpopular HP: 150MP: 30 Gender: Female Strength: 6 Agility: 18 Endurance: 15 Intelligence: 3 Spirit: 4 Evaluation: Because it resisted the erosion of biochemical viruses, the body has evolved, retaining the characteristics of the original creatures, and strengthening the body at the same time.

Liu Xin saw some differences from the detection operation, the name is a mutant mouse, not a biochemical dog like a puppy Doudou, and the evaluation is that it has resisted the virus and has evolved. "Does it mean that this rat or an animal has not become a zombie? If you still retain the characteristics of this creature, can you evolve as long as you resist the virus? "Although there are still a lot of things that I can't figure out for a while, but the others don't matter anymore, as long as you know that it's not a zombie, mice used to be afraid of cats, where am I going to find cats now? However, rats generally come out at night, and they are rarely seen during the day, so they may be afraid of light, and even if they are humans, their eyes will not be used to sudden strong light from the dark. So now there is another means, flashbangs. ”

Liu Xin did what he said, immediately took out the flashbang in the cashier ring and threw it behind him, and then continued to run out. Then there was a strong light, Liu Xin's eyes were stung by the light with his back to the flashbang, not to mention the rat swarm facing Liu Xin behind.

Through the delay of flashbangs, Liu Xin finally ran to the gate of the subway station. Who knew that Yu Yang actually sealed the entrance to the entrance, Liu Xin could only pick up the spear and slash towards the gate with all his might, and after unremitting efforts, the gate finally broke open. And the rats also reached the staircase, and Liu Xin could only lean on the gate of the subway and climb to the top of the subway exit.

The rats didn't care about Liu Xin, and continued to run towards the city after coming out of the subway. Liu Xin watched the steady stream of rats running out of the subway at the door of the subway, which can only be summed up by happiness, and at the same time he also had a deep hatred for Yu Yang. It wasn't until after the rats left that Liu Xin relaxed and opened the system record: "Ding, congratulations to the host for getting 3 points of second-level energy, 3 points of second-level energy for the current energy, and 101 first-level energy (when the energy reaches 1000, it will be automatically exchanged for the next level of energy, and the highest level is six-level energy.) ”

Liu Xin was so excited that he couldn't help himself, "I can finally get rid of the damn virus, and if I do this a few more times, 10 lives will not be enough to die." After Liu Xin exchanged the serum, he felt that he was pitted by the system, and the so-called serum was just a transparent liquid in a glass test tube. But the system told him that this was the serum, and Liu Xin, who couldn't, could only tilt his head and take the serum.

Liu Xin drank the serum as if he had drunk a glass of mineral water, and he didn't feel anything at all, and he couldn't help but feel cheated again. Then I opened the side quest: find 1 point of secondary energy in 6 days and exchange it for the virus of the serum to connect the body (completed). At this time, Liu Xin felt a hot current appear in his lower abdomen, which rushed from his lower abdomen to his head and emanated from the top of his head.

With the gloves rewarded by the task, Liu Xin immediately felt that his speed was faster, and the shape of the gloves also made Liu Xin quite fond of pure black fingerless gloves. At the same time, Liu Xin also felt that he had become a local tyrant, and he had to go to the system store to consume once, or he would be sorry for his remaining 2 points of secondary energy.

Liu Xin found that after he was digitized, no matter how serious the injury was, as long as the HP did not return to zero, he would not die, and the treatment of the injury could be treated only with HP recovery, which is equivalent to as long as the HP returned to the full value, Liu Xin's physical injury would be cured, and the common medicine for treating HP is the blood vial, such as the miniature blood vial that instantly restores 500HP, each vial needs 1 point of secondary energy; There are also small blood vials that instantly recover 2000HP, each of which requires 500 points of level 2 energy; And the legendary fairy bean actually instantly restores 80% of its HP and 50% of its HP in the next 30 seconds, and 5% every 3 seconds, but the fairy bean actually needs 100 points of level 6 energy to exchange. And Liu Xin started YY again, it would be nice if he used fairy beans to eat like Goku in Dragon Ball, but unfortunately he has no energy in his hands now, so he can only think about it. In the end, Liu Xin gritted his teeth and exchanged it, this is a life-saving thing.

Then Liu Xin entered the subway again, wanting to continue to go to the northern city through the subway. Maybe it was because the rats had swept it once, Liu Xin didn't see any creatures, and came to the boundary of the northern city safely, but when he came out, he found that it was already dark, and Liu Xin had to find a place to rest. In the past few days, because he was with Yu Yang, Liu Xin had eaten something casually every time, and he didn't let go of his stomach to eat, and now he was hungry with his chest against his back.

Liu Xin took out the braised beef in Najie and ate a whole cube at one time, which made Liu Xin feel that he had become a rice bucket, and it was estimated that everything he would eat in the future would be a large energy consumer. Liu Xin took out a radio from Na Ring again, and after a while, he received the channel: "This is the 14th military camp of the Southwest Military Region, and I am the commander of the barracks." We set up camp at the Jintai Hotel, which is 3 kilometers from Wal-Mart in the northern city, we have food and weapons to protect everyone, and we also ask the survivors to try their best to go to the Jintai Hotel and join us. This is the 14th barracks of the Southwestern Military Region, and I am the ······ of the barracks."

The next thing is to keep repeating the news of only one message. Liu Xin opened the map of the system and immediately found the Jintai Hotel, "I am now more than 20 kilometers away from the Jintai Hotel, it seems that I can only set off tomorrow, at most there will be half an hour before it will be dark, and it is estimated that the mutant beast will appear at that time." Even if you enter the F class, you don't dare to wander around outside. ”
