Lin Fei couldn't help but think of the high-level zombie in the department store, I don't know, does it have an energy crystal nucleus in its head, if so, then how can I solve those 'little brothers' under it?

The more Lin Fei thought about it, the more he felt that he was so weak and helpless.

Thinking of the dense zombies in the department store, Lin Fei's scalp tingled for a while, "However, at present, only that department store can have energy crystal nuclei, it seems that I have to take another risk", Lin Fei thought in his heart.

"However, that high-level zombie doesn't know what strength it is, Kuroko said at the beginning, the three of us join forces, we have a great chance of being able to defeat that zombie, and now Kuroko's strength has improved a lot, there should be no problem."

Lin Fei shook his head worriedly, interrupted this thought, and remembered the next thing:

Now it seems that there are only two ways to improve strength, the first is to collect energy crystal nuclei and upgrade the system, so as to strengthen the body of Lin Fei and his pet and improve his strength.

In the second way, Lin Fei can take some powerful mutant beasts as pets and assist Lin Fei, which can be regarded as improving Lin Fei's strength in disguise.

Although the first method requires the search for the energy crystal nucleus, which is time-consuming and laborious, it can directly strengthen Lin Fei's own strength, after all, his own strength is really strong.

Although the second method has an immediate effect, it is opportunistic, with the help of external forces, once the situation is special, Lin Fei cannot use pets to fight, or the pets are not by Lin Fei's side, then Lin Fei will become a lamb to the slaughter, and there is no power to fight back.

After weighing the pros and cons, Lin Fei decided to collect the energy crystal nucleus, although it is very difficult to find the energy crystal nucleus, but there is no free lunch in the world, if you want to become stronger, you still want to relax, then it is better to wash and sleep early, there is everything in your dreams.

After making up his mind, Lin Fei's heart fell to the ground, closed his eyes, and fell asleep peacefully, in the morning, Lin Fei got up and found that the scars on his original body had almost recovered, and when he touched it with his hand, there was only a slight pain, "Strange? When did my resilience get so good"? Lin Fei was puzzled, but he didn't care, after all, since the end of the world, Lin Fei had seen too many shocking things.

"Brother Fei, when are we leaving for the farm?" Early in the morning, Jiang Yu asked Lin Fei excitedly, "Oh, Jiang Yu, I see that you look good and are very excited, it seems that Wang Hai's punch didn't hurt you very much!" Lin Fei joked.

"Haha, Brother Fei, I was actually not seriously injured, I only took one punch, but it was very painful at the time, but you, Brother Fei, you were obviously seriously injured, but now you are jumping around, and you are still in the mood to joke, Brother Fei is really not ordinary", Jiang Yu said, and patted his ass by the way.

"Oh...... Hehe...... Yes", Lin Fei was speechless for a while, why did he joke about this matter when he was idle and had nothing to do, let Jiang Yu find out that he had also recovered, if he let others know that he was so seriously injured, it would be good to just sleep for a while, then he must not be regarded as a monster!

Fortunately, Jiang Yu just said casually, and didn't ask much, "Don't worry about it now, wait for a day, I'll go to the department store again, do something, I'll go alone, you stay and look after the house", Lin Fei said.

"Oh, okay, Brother Fei, you are busy, rest assured that the family will leave it to me, and it will definitely not hurt our sister Ruoxue", Jiang Yu patted his chest and promised.

Lin Fei didn't say anything more, went out of the door, and headed towards the department store.

When I came to the door of the department store, it was the same as the situation of Lin Fei Jiangyu last time, on the surface, it was calm and peaceful, as if it was very safe, if Lin Fei hadn't been cheated once last time, maybe I would have believed it.

Lin Fei looked through the door: in the hall of the department store, there were three or five more corpses, various weapons were scattered all over the ground, and the walls were sprayed with black-brown liquid—I didn't know that the survivor team was pitted by this group of zombies again.

Lin Fei didn't have time to sympathize with their miserable plight, he also had to do his own thing, Lin Fei stuffed the sunspot into his backpack, grabbed the drain pipe on the outer wall of the department store, and carefully climbed the net.

That's right, Lin Fei wants to decapitate this high-level zombie, he wants to 'take the head of the corpse king from the ten thousand corpses', directly kill this high-level zombie, and let them 'have no head', so that not only Lin Fei will get the energy crystal nucleus, but he can also work with Jiang Yu to clean up the zombies in it and take away the materials in the department store.

In order to make this group of zombies not only unable to catch fish, but also to lose the bait, they must know that humans are the most insidious and cunning, and the most cunning.

Lin Fei thought in his heart, and unconsciously climbed to the fourth floor, carefully moved to the window, and looked at the window on the fifth floor: the fifth floor seemed to be the staff lounge of the department store, and the small rooms were crowded with zombies.

"Kuroko, Kuroko! , do you know where that high-level zombie is? Lin Fei asked in his mind, "Ah! Master, this is so high, I ...... I'm scared", Kuroko's trembling voice came in Lin Fei's mind.

"This ...... How old are you...... Uh, no, how big is it, and you're still afraid of heights"? Lin Fei couldn't help but be a little speechless, "I'm afraid...... What's wrong with being afraid of Gao, I'm a dog, not a bird, it's a matter of course to be afraid of Gao", Heizi seemed a little embarrassed when he heard Lin Fei's words, and his confidence in speaking was a little insufficient.

"Haha, don't be afraid, it's very safe here, you won't fall, you have to trust the master, and when you have the opportunity in the future, the master will take you to the plane", Lin Fei said this, his tone was a little lonely.

Will there be a chance to fly in the future? In this apocalypse, the airport has become a paradise for zombies, and taking a plane has become a luxury, and it can almost be said to be an impossible task.

"Okay, let's not talk about that, Kuroko, can you find the exact location of that high-level zombie? There are too many rooms in here," Lin Fei asked.

"No, master, perception is a hazy feeling, you can only perceive a rough idea, and it can't be very accurate", Kuroko said helplessly.

"Okay, let's go in first, find a room to settle in, and stick to the wall like a gecko, it's really uncomfortable," Lin Fei said and carefully opened the window.

There were five zombies in this room, because the place was not large, so their location was relatively concentrated, as soon as Lin Fei opened the window, he smelled the breath of the living, and he screamed 'ho ho' and rushed towards Lin Fei.

The first zombie rushed over first, but due to the obstruction of the windowsill, this zombie couldn't reach Lin Fei at all.
