Wang Lei took out the dagger inserted in the giant cat's eye and began to perform a craniotomy on the giant cat.

Cutting open the scalp of the giant cat, Wang Lei didn't care about the violence and blood, and directly used both hands to tear the scalp of the giant cat hard, revealing the skull covered with blood. This is not a hospital, and there is no hemostatic equipment, Wang Lei can only rely on the touch of his hands to grope for the gap on the giant cat's skull, and insert the dagger into it, slide along the gap, find the weak point, and use his strength to pry his skull open violently.

After wanting to pry open the skull, he smashed the internal brain marrow with a knife and completely "killed" the giant cat. But after Wang Lei opened the other party's head, he found that in addition to the cerebral marrow, there was a "tumor" the size of a quail egg.

"I'll go! This giant cat has a tumor in its head, no wonder it wants to die! No, how does this thing seem to have been seen somewhere?" Wang Lei looked at the tumor and said in shock.

took off the "tumor" and took it in his hand to observe it carefully, Wang Lei found that this thing was somewhat similar to the "stone" he had eaten, it looked like a crystal clear natural crystal stone, but it was soft when pinched, but it was a bit like crystal jelly.

"Could it be that Wangcai gave me this kind of food at the beginning, and this is also the key to my immunity to the zombie virus?" Wang Lei looked at the "tumor" on his hand and muttered to himself.

"You mean, the magical stones you ate were taken from the heads of these mutant beasts?" asked Su Xue'er again.

"Maybe it's true, when Wangcai gave me the stone, it was covered in wounds, and those wounds didn't look like zombies were made at all. Now it seems that it may have fought the other mutants, killed them, and then took out the contents of the other person's head and gave it to me. Wang Lei guessed.

"Cut open the head of the German blackback, and see if there is anything like this inside. Su Xue'er thought of something, and hurriedly asked Wang Lei to do it.

"I'm sorry brother, although it is disrespectful to you to do this, but I am also doing this to save more survivors. Wang Lei saluted the corpse of the military dog, and then picked up the dagger to open the skull.

Now that the military dog has been sacrificed, and it is very likely that there is a drug in its head that is immune to the zombie virus, Wang Lei can't care about respecting or disrespecting.

After some effort, the head of the military dog was opened, and sure enough, a similar stone was found inside. The texture and color are much worse than those in the giant cat's head, except for the different colors, there is almost no difference from the one that Wangcai gave Wang Lei to eat, which makes Wang Lei even more sure that the stone that immunizes the virus and enhances the physique is what grows in the head of a mutant animal.

At the same time, the two finally figured out that the purpose of the giant cat wanted to kill the military dog, it was for the magical "stone" in the military dog's head. One such stone can make Wang Lei's physique undergo earth-shaking changes, which is much stronger than the brain marrow of hundreds of zombies, and of course the giant cat doesn't want to give up.

"You take this and eat it when you get back, so you're immune to the virus. The "stone" taken out of Wang Lei's giant cat's head was handed over to Su Xue'er.

"Didn't you find that this "stone" is very similar to the function of the crystal nucleus of the demon beast in the novel? If I guessed correctly, after the animal mutates, the magical changes it has come from this "stone", and the higher the stone, the greater the energy it contains. This giant cat has undergone a second evolution, and when you ate that kind of low-level stone, you were in pain to death, and I, an ordinary person, can't withstand such a huge amount of energy. Su Xueer connected several things and came up with a bold answer.

She actually linked the "stone" in the mutant beast's head with the virtual monster crystal nucleus in the novel. I have to say that Su Xue'er's imagination is very rich, and the reasoning given is also the most in line with the current situation.

Now that the end is coming, inexplicable pillars of light, inexplicable viruses, inexplicable evolutionary beasts, if human beings still rest on their laurels, look at these things with the so-called science, and dare not reason boldly and try boldly, then human beings will not be far from extinction. At least Wang Lei is a living example, he has evolved, he is not afraid of virus infection, and his body has also undergone changes that are different from ordinary people, and these changes are inexplicable by science.

"Isn't the crystal nucleus of this giant cat useless? I don't think there's anyone who can withstand such a huge capacity. Wang Lei also defined this strange "stone" as a crystal nucleus.

"Not necessarily, haven't you devoured the crystal nucleus of a first-level mutant beast? Your body has already been transformed, and you can be regarded as an evolutionary, with your physique, it should be no problem to absorb the crystal nucleus of this second-level mutant beast, if you really absorb the powerful energy inside, your physique will be one step closer. Su Xueer expressed her opinion.

They had never heard of the mutated animals before and could not name them accurately. Only ordinary mutant beasts can be called first-level mutant beasts, and evolved mutant beasts can be called second-level mutant beasts.

"Let's talk about this later, the purpose of our coming here today is to find guns and ammunition, and it has been delayed for so long, so let's go and find it." Wang Lei put the crystal nucleus in his pocket and changed the topic with haha.

He still remembers the pain of transforming his body with crystal nuclei, and now he has to try that kind of pain again, and he is not a fool, so he will not die by himself!

Su Xue'er also knew that the danger had not been lifted yet, there should still be a lot of zombies inside, and she still had to find weapons and ammunition, so it was not the time to absorb the crystal nucleus at all, so she was not serious with Wang Lei.

"Xue'er, do you say that there are really weapons and ammunition here? And these emergency lights are all on, do you say there will be survivors inside, if there are survivors, then they are all active soldiers, knowing our idea of hitting the arsenal, will they shoot us?"

"The emergency power storage system in the military restricted area can be maintained for half a year after the power outage, and this kind of underground fortification, the power storage equipment is even more powerful, even if all the people die, as long as the power is turned on before death, the minimum consumption is no problem to maintain for a year. As for whether the other side will allow us to use the ammunition depot, we will have to wait until we find these survivors. After the zombie outbreak, the only place where this base can survive is the material storage point, which is also the control center of the entire base, and the survivors are very likely to be in that place. Su Xueer explained.

is worthy of being a soldier's daughter, if there is no guidance from Su Xueer in this regard, even if Wang Lei knows that there is such a place, he will not want to get those weapons.

"And I'm sure there are definitely survivors here, and they are all living in the supply reserves, and if we find them, we will not only get enough weapons and ammunition, but also help from regular soldiers. Su Xue'er suddenly said such a sentence.

"How do you know that there are still living people in this base?" Wang Lei said curiously.

He followed Su Xue'er all the way and didn't hear anyone speak. Moreover, there is no camera installed inside this base, so it is impossible to find Su Xueer through the camera like Wang Lei did at the beginning.
