Dudian, Sham, and Zachi all fell on the dark blue ball with their eyes, and they couldn't help but be stunned, and their heads were ...... Drop a ball? This ball is a natural perfect roundness, and the color is dark blue and beautiful, obviously not some intracranial tissue sclerosis, but like a blue metal ball. Pen, fun, pavilion www. biquge。 info

It's just that how can there be metals in the brains of living beings?

Dudian was shocked, but instead of touching it with his hand, he poked the ball lightly with his short sword, and the tip of the sword stabbed on it and immediately slipped, pushing the ball down to the broken neck of the walking corpse.

It's so hard! Du Di'an's eyes moved, the activity of the hard object is poor, the infection speed is also slow, and it will not penetrate like a liquid, he has the isolation of gloves, if he touches it simply, it should be no big problem, and he immediately reached out and picked it up.

As soon as he caught this dark blue ball, Du Dian felt a thrill all over his body, and there was only one feeling from the nerves of his fingers, which was cold!

Extreme cold!

It was like holding an ice hockey ball, and he couldn't help but think of the frozen blood in this line of corpses, could it be because of this dark blue ball?

At this time, the cold air seemed to spread, crawling along the dark blue ball to Du Dian's arm, he felt that the temperature of the whole arm was rapidly decreasing, a little stiff, he couldn't help but put the dark blue ball on his other hand, soon, this other hand also felt a little frozen, at the same time, Du Dian felt cold all over his body, as if he was in the black snow season, extremely cold.

"How can it be, even if you are holding a piece of ice in both hands, it is just a frozen hand, how can you feel cold all over your body, and you feel cold from the soles of your feet." Du Dian was a little surprised, this was like playing with snowballs in winter, at most his hands were cold, but his body was warm, but at this moment he felt cold all over his body, as if his whole body was attached to a piece of ice.

He immediately put the dark blue ball on the ground, rubbed his hands together, and sighed, which made him feel a little warmer, but soon he felt a burst of hunger in his stomach, from the time he came to the outside of the giant wall to now, he hadn't eaten, he endured it, suppressed the hunger, looked at the dark blue ball in confusion, and suddenly, he thought of a reason.

"Absorb heat!" Dudian came to his senses, "This dark blue bead will absorb heat, just like saltpeter in black powder, saltpeter is not only one of the raw materials of black powder, but also can make ice, in this world, most alchemists have only mastered the use of saltpeter to make ice, but have not yet discovered that saltpeter mixed with sulfur can explode......"

Saltpeter makes ice because it absorbs the heat in the water, so the water freezes.

And he just felt that his whole body was cold, obviously, this dark blue ball also has the same heat-absorbing function as saltpeter, if it is grasped in the hand, it will absorb heat along the arm, until the heat of the body is absorbed, and the person's body temperature will also decrease, when it is reduced to a certain extent, it is natural that the heartbeat stops and freezes to death.

"No wonder, no wonder the temperature of these walking corpses is so low, so cold, it turns out that this thing is playing ghosts, but how did this thing come about, why did it appear in the minds of the walking corpses?" Du Di was full of curiosity in his heart, if it was said that someone had been colonized into their brains, it was naturally unlikely, after all, there were so many walking corpses, how much energy and time would it take to colonize them one by one?

"If it's not artificially colonized, it's grown by itself, but although the walking corpse is a human infected by the virus, it is flesh and blood after all, how can such a hard object like metal grow and have such strange characteristics?" Du Di was surprised by this, and at this time, a figure suddenly jumped down the stairs, which immediately alarmed several people in the room.

After seeing that it was Macon, several people breathed a sigh of relief.

Macon was also relieved to see that the three of them were there, and said angrily: "Scared me to death, I almost thought something had happened to you down there." ”

Sham scratched his head and said, "I saw Dean dissected and forgot to inform you." ”

Zachi reacted and hurriedly said, "You're down, what about those walking corpses?" ”

Macon rolled his eyes and said, "Of course I'm back, I'm tired, which of you will change." ”

"I'll go." Sham looked at the decapitated corpse, felt a tumbling in his stomach, and immediately said.

Dudian was interrupted by Macon, continued to think, but had no clue, couldn't help sighing, no longer continue to drill in this area, the most important thing is to survive now, suddenly, his eyes lit up, and immediately said to Zachi and Macon: "Follow me, go downstairs." ”

The two were a little confused, but they followed anyway.

Dudian came downstairs, saw that the group of walking corpses outside were led away, and immediately sneaked around the corner, cut off the heads of the two dead walking corpses with a short sword, and then rushed back to the building with their heads. ”

Macon was horrified: "You, when did you become so bold?" ”

"It's good to get used to it." Dudian said this, turned back to the upper floor, and according to the previous method, split the heads of the two walking corpses, and since the heads of the two walking corpses had been cracked, he easily cut them, and as he expected, there was also an identical dark blue ball inside.

When cutting the third head, Du Dian suddenly thought of a problem, and immediately stopped the previous rough cutting method, but slowly broke the head along the location of the cranium crack, and soon, he saw the picture in the skull, as he expected, the brain tissue in the skull was also extremely cold, as if it had been frozen, and the dark blue ball was lying in the package of brain tissue.

However, probably due to the crack of the skull, the brain tissue at the dark blue ball was somewhat damaged, Du Dian rummaged carefully for a while, and soon understood that this dark blue ball was the main reason for controlling the walking corpse!

There are two principles for the so-called destruction of the skull to kill the walking corpse, the first is to destroy the central nervous system in the skull, so that the skull cannot dominate the body, and the second is to destroy the connection between this dark blue ball and the brain tissue in the skull!

To put it simply, this dark blue ball is like making an ovary in the brain tissue, and it is not necessary to destroy the head to kill the walking corpse, as long as it is a strong concussion, the dark blue ball is shaken out of the ovaries of the brain tissue, so that the dark blue ball and the nerves in the ovarian wall lose contact, you can make the walking corpse stop moving, that is, kill the walking corpse!

After understanding this, Du Dian became more and more puzzled, what is this dark blue ball, why does it grow in the brains of the walking corpse, is it made by a virus? In this way, isn't this dark blue ball a virus condensation?

Thinking of this, Dudian immediately rolled the dark blue ball layer by layer with the fabric he picked up, wrapped it into a fist-sized ball, and then relaxed a little, and then handed two to Macon and Zachi, and said: "This thing can absorb body temperature and help us lower our body temperature, but don't hold it all the time, it will absorb the body temperature, and it is best to put it in a backpack." ”

Macon and Zaci looked at the two wrapped objects in amazement, and Macon wondered, "What is this?" ”

"I don't know, but after those hunters kill the walking corpses, they will dig out this thing in their heads, which means that it should be very valuable, otherwise these hunters will not turn a blind eye to such a thing as gold and go to take this thing." Dudian said that he had seen many walking corpses with their heads split open, and none of them had this in their heads, so it was obvious that they had been picked up by hunters.

Macon exclaimed, "You said that the hunters killed the walking corpses, just for this?" ”

"Perhaps."
