It's an oolong.

But it's no wonder that the oolong is not to blame, the Puxi Baichang Mine in tons, in addition to the mineral deposits distributed on the surface, he really can't think of what form it can exist.

The black magnetic world is not very large, and you can see the outline of the surroundings, which is probably a few kilometers to the northwest of Dashu Mountain. The camp has been explored, with an area of about 20,000 acres, not flat but without mountains, only some irregular craters like craters.

However, the survivors did not dare to go deep into it, because their heads would hurt, and if they entered it for more than 500 meters, they would have a headache and want to explode.

Zhou Yan was also very worried about whether he would have a headache.

"I wonder if my brain cell repair fleet can fix headaches?" Zhou Yan inspected the black land on one side and returned to the BAIC Warriors.

Drive back towards the Black Earth.

After entering the black earth, I suddenly felt as if I had come to a coal mine, and black occupied the field of vision. At this moment, his brain clearly felt a swelling, followed by a sudden throbbing of his temples, and a slight pain in his brain.

This pain is like a migraine, and you can't find exactly where it hurts.

He hurriedly turned on the retinal light screen of his left eyeball.

Sure enough, a new hint appeared.

- "Warning, Zhou Yan's cerebral cortex is disturbed by an unknown magnetic field, and the slight irregular discharge of neurons is disrupting the normal fluctuation of brain waves, and long-term interference will cause serious trauma to the brain, and even death. Please activate the brain cell repair group Lv1×1/1B as soon as possible to repair it. ”

"Start the brain cell repair swarm, repair!"

After activation, I saw the illusory figure on the top of the figure, representing the bright spots of the brain cluster, constantly flickering and turning. And in the next second, the slight pain in Zhou Yan's brain had disappeared.

"It's really okay, it's good!"

Zhou Yan breathed a sigh of relief, and drove the car to continue to stretch out towards the black magnetic world. Unconsciously, he came to the edge of an irregular pit, and when he saw clearly what was going on under the pit, his eyes almost didn't pop out.

There were hundreds of zombies, crowded together at the bottom of the pit, swaying unconsciously.

The bodies of these zombies are all pitch black, the same color as the black earth, and if it weren't for the clothes that could distinguish them, they wouldn't be able to see any difference.

"Is this a zombie mutation, or a group of black people becoming zombies!" Zhou Yan only had time to complain about this.

When those zombies heard the sound of the car engine, they immediately woke up from their state of confusion and began to roar one after another, rushing towards Zhou Yan.

Zhou Yan didn't dare to stop, so he turned the head of the car directly and ran outside.

The speed of the car was not fast, mainly because the zombies were running very slowly, and when he drove out of the border of the black magnetic world and returned to the parking lot of the Shushan Martyrs Cemetery, there were only three zombies left behind the car staggering and running.

Brake, push the door and get out of the car.

Taking out the iron gun from the back seat, Zhou Yan walked towards the three dark zombies, he planned to hunt these three zombies and take out the radiation nucleus in his brain.

The Radiation Nucleus replenishes Sita's Radiation Gas, which is much faster than eating insect meat.

The emergency spear technique was activated, and the iron spear was in his hand, like a terrifying dragon, stabbing straight into the head of a dark zombie. But unexpectedly, the imaginary headshot did not happen, and the tip of the gun was stuck in the zombie's head, and it did not explode at all, but only pierced a small hole in the zombie's skull.

The zombie was knocked to the ground by the force, stretching out his hands and feet, trying to get up again.

Unaffected.

"What's the situation!"

Zhou Yan only felt that the feeling of stabbing the zombie's head was wrong, it was like a stabbing a large piece of iron, and the force of the shock when the stab hit made Zhou Yan's arm numb.

Irrationality.

Although he was surprised, his reflexes were still there.

Quickly pull out the iron gun, ready to make up another shot, and shoot the zombie in the head. It's just this delay, and the other two zombies have already pounced, forcing Zhou Yan to give up the gun. Turning around, an iron spear thundered on the ground and stabbed the head of another zombie, with the same result, only a small hole could be pierced.

It's the same with the body of a zombie.

The three zombies have become copper skin and iron bones, which cannot be regarded as invulnerable, but it is indeed very laborious to leave wounds on their bodies.

Zhou Yan was ruthless, and chased a zombie and stabbed seven or eight shots in a row, all of which were stabbed in the same position on the door of the head, and finally, with a click, the tip of the iron gun completely pierced into the zombie's head.

Twist it lightly and pull it out again.

Dirty blood splattered, and the zombies immediately fell to the ground, truly inactivated.

The old trick was repeated, and Zhou Yan spent another two minutes killing and inactivating the other two zombies one by one. The tip of the blood-stained spear had been bent off, and there were several gaps in it.

"Bad luck, zombies have become like they are made of iron!" Zhou Yan pulled out the dagger, prepared to open the skull of the zombie, and took out the radiation nucleus inside, "This change should be caused by the interference of the black magnetic world, could it be that the black magnetic world changed the zombie's body to iron?" ”

The dagger stabbed into the lost head with a muffled thud.

It's not like it's iron.

Touching the zombie's black skin with your hand is very hard, but it still has the characteristic softness of the skin, but it can block the dagger. But Zhou Yan changed a little and cut with a dagger, and found that it was not difficult to cut, and he could cut the black skin with a little effort.

Revealing the blackened skull inside.

The skull had been pierced with an iron spear, and the hole was enlarged with a dagger, and a small colander was put in to stir the brain, and the radiation nucleus was quickly scooped out. The radiation nucleus in the zombie's brain was much larger than the subway station zombie he hunted before, at least two the size of the zombie over there.

Wiped the radiation nuclei with the zombies' clothes, put them in a small bag, and took out the radiation nuclei of the three zombies in turn.

He thought about it, put a zombie into a black plastic bag for garbage, tied the mouth of the bag, stuffed it into the back compartment of the BAIC Warrior, and brought it back to the laboratory as research materials.

After all, it's a new form of zombie.

"It's simply called the Black Iron Zombie, referred to as the Black Corpse." He thought about it, ran to the zombie again, and forcefully broke off a broken skull fragment.

Wipe vigorously off.

It was found that the black on the surface was indeed the black of the bones themselves, not the color stained by stained blood. It shows how strong the pollution ability of the black magnetic world is, from the skin to the bones, everything has turned black.

At the right time.

On the retina light screen of the left eyeball, a text prompt appears.

- "Hint, found ∑ energy crystallization at a distance of 0 centimeters. ”

"Sigma Energy Crystal!" Zhou Yan was instantly excited, but he didn't expect that in the skull of the zombie, he also found a Sigma energy crystal.

"What the hell is going on!"

"Why can you find signs of omega evolution liquid, sigma energy crystal, and Sita radiation gas on all kinds of zombies, bugs, and plants?"

"Where did the four substances, including the Puxi Variant Mine, come from?"

Many thoughts flashed in an instant, Zhou Yan looked at the skull in his hand and decided that he would hunt more zombies in the future. Maybe Sigma energy crystallizes, and scraping the skull of a zombie is faster than drinking worm blood.

Quickly scraping all the crystallized particles in the brains of the two zombies, Zhou Yan looked into the distance and thought in his heart: "There are so many zombies in the big pit, are they all hunted and killed, and collect all the sigma energy crystals...... Maybe you'll be able to gather enough to produce a new fleet? ”
