Leng Yan naturally couldn't go toe-to-toe with this mutant zombie, and a long knife with blue light appeared in his hand, slashing directly at the mutated zombie's bone-revealing arm.

The arm of the mutant zombie was like paper paste, and it was easily cut off by Leng Yan, and then Leng Yan kicked it in the abdomen hard, and fell directly from the roof with a pop.

The fourth-order mutant zombie that originally looked invincible was kicked out so lightly, and it was also a little unexpected for Leng Yan, he originally thought that he would need to fight it for a few more rounds.

At the moment when Leng Yan frowned, a pair of white claws appeared on the edge of the rooftop, and the mutated zombie did not fall from the upper floor, but grabbed the edge of the rooftop with its still intact arm, and was struggling below to climb up at any time.

A figure suddenly jumped high, fell rapidly in the air, and pounced straight on Leng Yan, who was still standing in place.

Leng Yan didn't relax in the slightest, and the moment it pounced on him, the weapon in his hand also stabbed directly towards the figure.

'Poof,' the long knife in Leng Yan's hand stabbed directly into its eye socket, its head was deflected, and the long knife slashed directly out of his head, but it didn't hurt its key parts.

Black blood flew in the air, and the mutant zombie retreated extremely quickly, it obviously had the intention of retreating, but the covetousness of the man's body made it hesitate a little, and it did not choose to leave at the first time.

Leng Yan naturally couldn't give it a chance to retreat, and while it coveted him, he also had an infinite yearning for the corpse core on its forehead.

A huge spider-like crack suddenly appeared under Leng Yan's feet, spreading in all directions.

Leng Yan jumped up, and the long knife in his hand suddenly more than doubled, and slashed directly towards the mutated zombie's body.

The mutant zombie had retreated some distance, and according to Leng Yan's weapon length, it would not have been able to reach it, but at the moment when it was about to touch its body, the weapon suddenly changed its length, catching it off guard.

At the moment when the mutated zombie reached out to parry the long knife, the long knife instantly dissipated into nothing, and what greeted it was a huge fist.

Leng Yan's punch sank vigorously, and the sternum of the mutant zombie collapsed, and the body slid straight back, and a deep ditch appeared on the originally flat floor, and the body of the mutant zombie fell deep into the ground.

Leng Yan didn't even want to wait for a moment's chance, and saw that the mutant zombie was constantly struggling, its lower body had completely sunk into the ground, but its upper body was exposed, as if it was stuck by something.

Fortunately, the downstairs was already empty at this time, otherwise the lower half of the body that appeared out of thin air was basically only a muscle outline, which was estimated to scare the survivors in the house to death.

A blue light fell from the sky and slapped directly on the head of the mutated zombie, which had no hair left in the skull, and cracks appeared on the skull, which spread out like lime wrapped in the wall.

At this time, countless huge cracks had appeared on the entire rooftop, taking the location of the mutated zombie as the origin, spreading in all directions.

If it weren't for the fact that there was no problem with the color of the corpse core, Leng Yan would most likely doubt the authenticity of the mutated zombie level in front of him.

He could now clearly see the mutated zombie's exposed brain stem, and the white brains were exactly the same as the pig brains he had eaten in the hot pot before.

The mutant zombie desperately tried to pull its body out of the ground, but a steel bar was stuck on its waist impartially, allowing it to struggle in every way, and the original intact musculature on its body was detached from its body piece by piece, and it fell directly into the room below one after another like a puddle of rotten meat.

The mutant zombie has no pain, so the fallen muscle tissue does not have any direct effect on it, it seems to be unaware, it is still like a drowning man constantly moving the arm that is still intact, and the legs are constantly exerting, but its condition is still not improving.

The mutated zombie's struggle came to an abrupt end, and a long knife glowing blue glittered into its head, penetrating its brain, and the originally well-patterned brain turned into a mess of paste and slid down the long knife.

Leng Yan smoothly pulled out the corpse core and put it directly into the space.

The fact that this fourth-order corpse core came so easily was indeed beyond his expectations.

Is it true that he is already so strong? He looked down at his hands, but couldn't get any answer.

At the moment when the fourth-order corpse core was included in the space, the fourth-order corpse core tree that had stopped growing for a long time finally moved again, like a child who had just woken up from a big dream, stretching its arms upwards with all its might. But this situation did not last long, and soon the corpse core tree, which had finally become active, fell into a deep sleep again because the corpse core was absorbed.

"It's really troublesome, we still have to find at least another fourth-order corpse core," Leng Yan observed the growth progress of the corpse core tree from beginning to end, and shook his head a little speechlessly.

He once again set his sights in the direction of the supermarket, because of the death of the fourth-order mutant zombie, the remaining mutant zombies had a tendency to move again, but most of them had a certain amount of wisdom, knowing that humans who could kill fourth-order zombies would not provoke them at will.

Therefore, Ji Sanqin and his party became the primary target of their attack, according to the expectation of the fourth-order mutant zombie, after it cleaned up this man with teeth and claws, it would go to harvest the only human who could interest it, but at this time, these plans had obviously been ruined.

At this time, they didn't need to suppress their true thoughts anymore, and chased in the direction of Ji Sanqin's escape.

Leng Yan's battle with the fourth-order mutant zombies was actually only a few minutes, and during this time, Ji Sanqin didn't run too far, because he felt that there were many people who could attract firepower for him, so he also had a lot of spare time to go back to the place where he lived before and take everything he could take with him.

When he walked out of the door, he was completely dumbfounded, and the dense mutated zombies rushed towards his location, and the ordinary survivors who followed him before had all become the food of those ordinary zombies, and they were pressing on the ground and biting, and the red blood spread into a small river, flowing towards the low-lying places.
