Wu Feng was thinking about how to get out of trouble, but he still underestimated Zhao Yue's murderous intent towards him, thinking that he had an ability and had extremely huge research value, Zhao Yue would not easily kill him, just in the blink of an eye, Zhao Yue appeared in front of him, and a palm was imprinted on his Heavenly Spirit Cover.

In an instant, Wu Feng's brain was shocked into brains, the whole person softened, and the flames on his body gradually extinguished.

"Hongmen?" Looking at Wu Feng who fell to the ground, Zhao Yue muttered to himself.

At the same time, he stretched out two fingers, like sharp knives, but easily penetrated Wu Feng's skull, and took out a walnut-like brain nucleus at the pineal gland, with an uneven surface, almost no different from the brain nucleus of the mutant.

"Sure enough! Wu Feng was infected with the Reaper Virus, and although he did not become a living dead, his body also underwent unknown changes, so he had a fire ability, which is considered evolution? Zhao Yue muttered to himself.

I saw that he put the brain nucleus on the table, and then took out a wooden box from a drawer, this wooden box has two layers, each layer is divided into ten small compartments of the same size, the upper layer is placed in five brain nuclei, and the lower layer is placed in two brain nuclei.

Although these brain nuclei look the same, they are naturally different when they are separated by Zhao Yue, among them, the upper brain nuclei are the brain nuclei of the S-type mutant, and the two brain nuclei in the lower layer are the brain nuclei of the D-type mutant, and these brain nuclei are all Zhao Yue's trophies.

I saw that Zhao Yue randomly selected a brain nucleus from the upper layer, and then with a flick of his finger, the brain nucleus of the S-type mutant flew out with a 'whoosh', and flew into it along the hole in Wu Feng's eyebrows.

The brain nucleus of the S-type mutant is soaked in the cerebral plasma, as if it has been activated, and it can be vaguely seen that there are hair-sized whiskers growing from the brain nucleus, as if they are about to take root and grow.

Seeing this scene, Zhao Yue's expression did not move, it has been a month since the outbreak of the Reaper virus, although the time is short, it has caused an unprecedented disaster, but because of this, all forces, especially China and the United States, have a thorough understanding of the research of the Reaper virus.

It's just that these things are still secret, and it is impossible for people without a certain level to know about them, even if Zhao Yue's quasi-father-in-law, Liu Jianguo, is not of a low level, but he only knows some preliminary information about the Reaper virus, which is enough for him to deal with all kinds of troubles that he may encounter outside Cloud City.

As for something deeper, he is not qualified to know yet.

In this way, Zhao Yue doesn't know much, but Zhao Yue's background is extraordinary, while determining the practice of martial arts in the real world, he began to pay attention to biology, especially the knowledge related to human biology, plus he has the ability to never forget, Zhao Yue's knowledge in biology may not be as good as that of a doctor of biology, but it has also reached the level of a graduate student in biology, and it can also be said to be a senior talent in the biological world.

During Zhao Yue's time in Cloud City, although he did not deliberately study the Reaper virus, he also studied and observed it with the eyes of scientific research, and naturally had his own gains.

Zhao Yue once did an experiment to feed a living dead person with the brain nucleus of a mutant, and in just a day or two, the brain nucleus would be digested by the living dead, and then regenerate a new brain nucleus at the pineal gland location, and the living dead would also evolve into a mutant.

Under Zhao Yue's observation, the brain nucleus that sank into Wu Feng's brain hole grew countless strands as thin as hair, which wanted to take root in the corpse, release a high concentration of the Death Virus, and transform the corpse into a living dead, and then evolve to form a new mutant.

However, after waiting for ten minutes, Wu Feng's corpse did not change in the slightest, and the flesh whiskers that grew out of the brain nucleus shrank back.

"Sure enough! Wu Feng was already immune to the Reaper virus. Zhao Yue muttered to himself, but confirmed his guess.

Then, Zhao Yue called out and called the people of the Thirteenth Squadron in, Li Ming and the others saw Wu Feng lying on the ground, and naturally understood something, and at the same time breathed a sigh of relief in their hearts.

In front of the members of the 13th Squadron, Zhao Yue took out the brain core, seeing this scene, the team members couldn't help but show a look of surprise, as Zhao Yue's subordinates, they naturally knew that if the braincase of the mutant took root in the new 'soil', it would irreversibly become another mutant.

"You've all seen it! Wu Feng is already immune to the Reaper virus. Looking at the team members, Zhao Yue said lightly.

"This is because Wu Feng was infected with the Reaper Virus a long time ago, but he did not transform into the living dead, but he has evolved, and he is immune to the Reaper Virus while also having a fire ability." Zhao Yue said lightly.

"Abilities?" These two words made a group of team members suddenly surprised, although the ability has never appeared in the real world, but under the rendering of various film and television works, the ability has long been known to the world.

"This brain nucleus was dug out of Wu Feng's head, and I guess it's the root cause of the ability and immunity." Then, Zhao Yue put the brain nucleus of the mutant body, and then picked up Wu Feng's brain nucleus and introduced it to everyone.

"According to my guess, the brain core of the mutant can make a living dead become a mutant, so Wu Feng's brain core should also have the same effect, which can make people have special abilities and be immune to the Death Virus." Speaking of this, Zhao Yue paused, glanced at the team members, and continued.

"Of course, this is just my guess, I wonder if anyone wants to try it? Do this one test? ”

As soon as Zhao Yue's words fell, the expressions of the team members changed, they had no doubts about Zhao Yue's words, because Zhao Yue had no need to deceive them, and the scene just now also happened in front of them, Wu Feng's corpse was indeed immune to the Reaper virus.

However, there is a great risk in rashly taking Wu Feng's brain nucleus, but the fact that the mutant brain nucleus can allow the living dead to evolve into mutants provides a certain amount of protection, but the risk is still huge, and a little carelessness will have irreversible major consequences.

No one wants to joke with their own lives, but now in this environment, human life is the least valuable, the Grim Reaper virus has broken out so far, burying millions of people, and only today have they heard the word "ability", which shows that this brain core is extremely precious.

Moreover, if the experiment goes well and the experiment is successful, then the person who takes the brain nucleus will not only be immune to the Reaper virus, but also have an ability.

It is said that half of the profit is enough to make people take risks, so it is needless to say that the profits are doubled, and the only brain core so far, if it succeeds, then the income is not as simple as doubling.

As a result, most of the 13th Squadron expressed their willingness to try, despite the risk of being used as guinea pigs if they succeeded.

In the end, the decision fell on Zhao Yue's hands.

"Money to the East! It's up to you. ”

Zhao Yue selected a person, this person is a young man in his twenties, a native of other provinces, a farmer, who has long been a lonely person in this disaster, who turned out to be working on a construction site, young, strong, ordinary-looking, dark-skinned, but his eyes are bright, and Zhao Yue sees an ambition that is not satisfied with the status quo.

Moreover, Qian Xiangdong was the first person to make a choice, which shows that he has ambitions and decisions, so Zhao Yue chose it.

"Thank you, Captain!" Qian Xiangdong showed a touch of joy, he had seen Zhao Yue feed the brain nucleus of a mutant to a living dead, and the immortal would become a new mutant within two or three days, in his opinion, taking Wu Feng's brain nucleus, even if it was risky, still had a great success rate.

Zhao Yue handed Wu Feng's skull to Qian Xiangdong, he picked up the brain core and hesitated slightly, but in the end he gritted his teeth and swallowed his stomach.

Next, Zhao Yue and a group of team members began to observe the changes in Qian Xiangdong.

At first, Qian Xiangdong didn't change much, but then his body began to heat up, and then he felt itchy all over his body, becoming more and more uncomfortable, looking at his painful appearance, Zhao Yue knocked him unconscious.

Even so, Qian Xiangdong, who fainted on the ground, kept twitching, and although he passed out, his face still showed a distorted expression of pain.
