"I actually upgraded, how did I upgrade? Is it because of the battle just now? Lin Hao asked curiously.

"Not really!" Dogan directly denied.

Lin Hao began to meditate, wasn't it because of the battle? That's because of what.

Suddenly, Lin Hao remembered the smell that attracted him yesterday. When Lin Hao killed the center zombie, he took out a bright red sarcoma from his head, and then ate the sarcoma himself.

"Is it that sarcoma?" Lin Haohu asked suspiciously.

"That's right, it's the crystal nucleus, that is the crystallization of the essence of the zombies, and only when the crystal nucleus appears, can the zombies evolve. I'm sure you can feel it, this second-level zombie is obviously much higher in IQ than the zombies around it. Dogan said.

Lin Hao nodded, indeed, other zombies would not provoke.

Lin Hao couldn't help but call up his attribute panel again.

"I didn't expect the upgrade benefits to be so good, and each attribute has been added by 5, except for the evaluation exercise. Some eggs, everything else is good, and his spirit has actually reached thirty. Lin Hao said complacently.

"This is an additional benefit given by the system, the first upgrade adds 5 to each attribute point, and only three attribute points will be added for each subsequent level." The dog ruthlessly pierced Lin Hao's illusions.

“...... Forget it, that's not bad, at least I'm not at the bottom now. The second level actually costs 500 experience points, how is this experience point calculated? Lin Hao asked.

"The current full XP multiplied by 5 is the XP of the next level." Dog Dan said leisurely.

Lin Hao was stunned. Forced: "That means that level 3 to level 4 requires 2,500 experience points, and level 4 to level 5 requires 12,005?" No way. ”

At the same time, what caught Lin Hao's attention was the title.

"What about this title, I'm also a butcher now, what will happen if I am facing the center zombie?" Lin Hao asked.

"With skill control, you can blow up the opponent, and with your body, the opponent will blow you up. Because you're already level 2, you've unlocked a lot of permissions, but you don't have the permission to know the title name for the time being. Dogan said.

Lin Hao silently cursed a sentence and said, "Then I have permission to know about it, you can tell me." ”

"When you reach level three, the speed attribute point will increase by 5, the other attribute points will be 3, the strength attribute point will be increased by 5 at level five, and the others will remain the same, and the physical strength will be increased by 5 at level seven, and the spirit attribute point will be increased by 5 at level nine." Dog Egg Road.

Lin Hao said speechlessly: "Are you going to tell me that the zombies of our spiritual department are the most unlucky?" ”

"No, I'm telling you, it's best to take a detour when you encounter a third-level speed zombie, a zombie with a fifth-level strength attribute point will also give me a detour, and a seventh-level physical strength cow. It's the same with the force, level nine... Level 9 is your world. Dogan said.

"I almost understand, the spiritual department belongs to the early weak and strong in the later stage, so when the early stage is level three, five, and seven, when I meet the zombies of these departments, I can run as far as I can." Lin Hao said speechlessly.

"That's right"

"Will you only rely on hunting high-level zombies to upgrade in the future?" Lin Hao asked.

"That's right."

"Will hunting the zombie crystal nucleus of the same line increase its own spiritual power?" Lin Hao asked again.

"That's right."

"Zombies in other departments can only increase experience points!"

"That's right."

"Would you say anything else besides yes?"

"Fuck off"

So Lin Hao opened his eyes.

Through the window, Lin Hao obviously found that it was already night outside. Lin Hao touched the soft quilt under him, and saw the little girl squatting in the corner.

The little girl was already asleep, her eyes slightly closed at the moment, her brow furrowed, as if she was having some nightmare.

Lin Hao slowly leaned over, this time, Lin Hao's mind was really simple, he didn't want to eat her, just looked at her quietly. Lin Hao really feels that this little girl is very similar to his sister, if her sister is still alive, she should be as cute as her.

"Ah~~" The little girl's sleep is very shallow, after all, in this environment, who dares to really fall asleep? In peacetime, this kind of child must be the heart and soul of the parents, and it is normal to study and play all day without worry, and sleep like a dead pig.

But now, not even a child can fall into a deep sleep, and it is hard to imagine how bad the surrounding environment is.

"You... You're awake. The little girl said timidly.

Lin Hao nodded.

"Are you hungry?" The little girl asked again.

Lin Hao shook his head.

Lin Hao obviously saw the little girl breathe a sigh of relief.

"Are you sleepy?" The little girl asked.

Lin Hao didn't know how long he had been asleep, and he didn't feel sleepy at all, so he pointed to the bed, and then to himself and outside. The meaning is obvious.

Although the little girl still didn't let down her guard against Lin Hao, maybe she was really too sleepy, and the two didn't have much to talk about, so when the little girl returned to the bed, she fell asleep immediately.

Lin Hao carefully checked the doors and windows, and through the windows, Lin Hao locked the door tightly, ensuring that no zombies would open it because they heard the movement and touched it slightly, so he left with confidence.

When Lin Hao came outside, he felt that there was a very abundant energy in his body, even if he let himself run 10,000 meters, he was afraid that he would not even blink his eyes.

Lin Hao came below mainly to find something to eat, not for him to eat, but for the little girl. After turning into a zombie, Lin Hao's five senses were much more sensitive, and the movement in the little girl's stomach naturally couldn't escape his ears.

On the first floor, a black schoolbag with blood stains lay there quietly, which was protected by the little girl's sister before she died, but when the little girl's sister became a zombie, she abandoned the bag.

Lin Hao opened the bag, which contained all kinds of crispy noodles and a few bottles of mineral water, and Lin Hao first carried the bag on his back. The little girl was sleeping, and he didn't want to disturb her anymore.

"How are you going to settle that girl?" Dogan asked.

"Send her to a place where there are people." Lin Hao said.

"How do you know where someone is?"

The dog's question made Lin Hao fall silent, does such a thing as a survivor base really exist? Lin Hao didn't know, and of course Lin Hao didn't know, the system escaped from the largest survivor base.

"No matter what, I'm going to try, I can't let a little girl mess with my zombie, what if I accidentally hurt him one day?" Lin Hao said.

When Lin Hao saw the electronics laboratory on the first floor, a flash of inspiration suddenly flashed.

"Yes, if you have a survivor base, you can't build a network, but if you have a radio, you might be able to find a useful channel." Lin Hao said.

The dog was suddenly surprised: "Yo, you can make a radio as a computer student?" ”

"You don't understand this, I was an electronics enthusiast before I learned computers, and the radio is the simplest electronic accessory, and it is very easy to assemble." Lin Hao entered the electronics laboratory with some excitement.
