Hearing Ye Hao's promise, a smile appeared on Scar's face, and those horizontal and vertical scars were pulled, making his face look a little more hideous than when he didn't smile.

"Okay, little brother, please wait a moment, let's leave after taking the brain nucleus."

"Uh...... What is a brain nucleus? ”

The three of them stopped what they were doing and looked at Ye Hao together. Being watched by six eyes, Ye Yu felt embarrassed.

"You don't know what a brain nucleus is, so why are you killing these mutants?" The pole asked with a strange expression.

"If they want to eat me, of course I'm going to kill them." Ye Yu replied confidently.

The three of them looked at each other and exchanged a few strange looks. Scar looked at the corpse at Ye Hao's feet, with a hint of greed in his eyes, he looked at Ye Hao again, turned his mind a few times, and finally sighed: "The brain nucleus is a stone condensed in the brain of the mutant, and the stronger the mutant, the stronger the brain nucleus." ”

"Oh...... That's right. Ye Yu nodded, this is probably what kind of inner pill, magic crystal or something like that, he thought about it and asked, "Then what's the use of the brain core?" ”

"The brain nucleus has a lot of uses, and if you eat it directly, it can make people mutate, and ordinary people can't control this mutation, and they will directly become mutants. Some lucky guys can withstand the mutation and become semi-mutants. However, the greatest use of the nucleus is to sell it to people in the 'big city', or ask them to help make it into a genetically modified potion. ”

"Wait, wait, what did you just say?" Ye Yu suddenly heard a word that he didn't expect.

Regarding Ye Yu's reaction, Scar was also confused. He frowned and repeated, "I just said that the brain core can be sold to people in the 'big city', or pay for it yourself to make genetic modification potions. ”

"Basis - cause - change - creation - medicine - water." Ye Hao said word by word, "Are you sure it's genetic modification?" ”

Scar nodded, not knowing why the other party reacted so much.

Ye Yu held his head in distress, he felt that his brain was about to explode.

Hasn't the world degenerated into primitive times? It's just a car if you have it, it is estimated that they were all sealed and dug up before, but what the hell is genetic modification!

This is genetic modification! The highest scientific and technological achievement of mankind, no, even at the time of Ye Hao, human beings' understanding of genes can only be regarded as scratch skin, let alone genetic modification.

Therefore, after the abolition of human civilization, the level of science and technology has risen? I don't believe this when I killed Ye Yu, science and technology, without a long-term accumulation, without the inheritance from generation to generation, it is impossible to come at all. Every progress in science and technology is supported by the whole society, and it is absolutely impossible for science and technology to progress in this situation where human society is on the verge of collapse.

Seeing that Ye Yu was deep in thought, Scar didn't bother him, but just gestured to the two subordinates. The pole and the pillar nodded, each grabbing their own mutant and smashing their heads, 4dd

Ye Yu happened to be depressed and couldn't figure it out, and when he raised his head, he saw such a bloody scene, and the nausea that he had endured for a long time finally broke out, and he ran to the side and vomited wildly.

The two young people seemed to have long been accustomed to this, and the pole looked at Ye Yu vomiting excitedly, and said proudly: "Spit it, spit it, spit it a few more times and you will get used to it, I vomited more than you when I first made it, good guy, I can't eat for three whole days." But then I got used to it, have you ever tasted the brains of mutants, it's delicious. ”

"I'm a muddy horse." Ye Yu had already vomited almost, but after listening to the words of the pole, he was nauseous again, lowered his head and continued to vomit.

Scarface looked at the rod helplessly, eager to give him two more slaps.

It wasn't until Ye Yu vomited the contents of his stomach that he even vomited out the yellow bile water, and he finally recovered his breath. When I looked up, I saw that the pole and the pillar each held an irregular crystal in their hands. Although he still felt disgusting, driven by curiosity, Ye Yu still leaned over.

The two crystals were about the size of thumbs, and there was a gray silk thread wrapped in the middle of the crystal, and Ye Yu looked closely, the gray silk thread was still faintly flowing, as if it had some kind of vitality.

"It can't be some kind of parasite or something, right?" Ye Yu thought of "Resident Evil 4" that he had played before, and parasites would appear after the zombie headshot in it.

Scar shook his head and said, "It's not a bug, I once smashed a brain nucleus, and there is no living thing except for a wisp of gray smoke."

"Boss, look, this time the brain core is bigger than ever." The pole said happily. Scar walked over and turned over the corpse of the mutant, pinched its hands and feet a few times, got up and said: "It seems that these mutants have been used vigorously for a long time before they die, and all their potential has been stimulated, but they have not died after a fierce battle, and their potential has not been released, so the brain nucleus should appear larger than usual." ”

Ye Yu was slightly shocked, Scar only speculated the situation by examining the corpse, and Ye Yu was secretly admired by his rich experience.

The two of them carefully tightened their brain nuclei into their pockets, and turned their eyes to the pile of corpses at Ye Hao's feet.

"Little brother, don't you take the brain nucleus?"

Ye Yu glanced at his feet, even though he knew that these brain nuclei should be very valuable in the city, but when he thought of the disgusting feeling of taking the brain nucleus, his stomach felt uncomfortable again. He waved his hand and said, "Why don't you help me get it, take it out and divide it in half of you." ”

"It's a good feeling." As soon as the pole was about to be put on when he rolled up his sleeves, Scar pressed his shoulder and said in a straight voice: "Little brother, you just came out of the wilderness, and you may not know the price of the brain nucleus." The pile of corpses under your feet, if the brain cores taken out are of the same quality as these two ones, then at least a large amount of money can be sold in the city, and even if you don't need money, these brain cores can be exchanged for a lot of materials. ”

Ye Yu felt a trace of emotion in his heart, even if he knew that Scar was trying to win him over, but the other party's upright personality also made people feel a little more good.

"Otherwise, we'll take out the brain nucleus for you, and when we get to the city, you can invite us to have a drink."

"Okay, then I'll trouble you." Ye Yu said and walked to the side, twisting his head, not wanting to see the scene of taking the brain nucleus again.

Soon, all the corpses were cleaned up, and the Blood Knife Team not only took out the brain nucleus, but also took away some of the better quality teeth and claws, Ye Yu was furious, but after so many days of exercise, his nerves had become extremely thick, as long as he didn't eat these humanoid monsters, he could still accept it.

"Little brother, this is your share." Scar thoughtfully grabbed the military uniform of the rod, wiped every brain nucleus clean, and handed it to Ye Yu in the rod's resentful eyes.

Looking at this large handful of crystals, Ye Yu rubbed his hands and said with some embarrassment: "Uh...... You see, I don't have a place to put it here, so I'll put it there first. ”

"Okay, my little brother can trust me, and I won't be hypocritical. Don't worry, when I get to the backing city, if my scar is greedy for a brain core, I will be eaten by the soul beast tomorrow. ”

Believe me, don't I have no clothes? Ye Hao said in his heart, although the scar looks like a righteous cloud, but as the saying goes, knowing people and faces does not know their hearts. Ye Yu didn't look at the end of the world, in this kind of environment, how low the lower limit of people can be is definitely beyond your imagination, and he can see the greed in Scar's eyes just now.

"Let's go, little brother, let's go get you something to wear first." Scar jumped into the jeep and greeted Ye Hao.

Ye Yu was not ambiguous, he sat on the co-pilot, and as soon as Scar stepped on the accelerator, the jeep let out an earth-shattering roar and rushed forward.
