What kind of existence is a fourth-order zombie, Yu Fei doesn't know, he only knows that it shouldn't be something he can deal with.

Weak, space-cutting...... Yu Fei's strongest attack methods came out frequently, but they were all in vain, and none of them could break through the protection of the zombie liquid and really hurt the zombie.

However, Yu Fei did not give up, and still kept attacking.

And as time passed, the size of the meat ball zombie was slowly getting smaller, and the zombie liquid around his body was also thinning, and at this time, Yu Fei's attack could hurt it!

Yu Fei's eyes lit up, this zombie is not invincible!

And this zombie did not grow into a 4th order zombie as Yu Fei expected, it is still a 3rd order zombie!

Knowing that the liquid would be able to hurt it after it disappeared, Yu Fei was not in a hurry to attack, he held a black and blue iron bow in his hand, a prepared throat-sealing crossbow hung on his right waist, and a tiger bone soul-breaking knife hanging on his left waist.

It took more than twenty minutes to wait, and finally, at a certain moment, the zombie completely got rid of the entanglement of the liquid, and the originally huge ball of meat, except for some debris and waste discharged from the ground, was all integrated into its slightly strong body, which was only more than two meters high!

Roar!

The fused zombie let out a roar, sweeping away the silence before, and at this moment he regained his thirst for fresh blood and roared towards Yu Fei to kill.

Sou!

Yu Fei, who had been waiting for a long time, shot an arrow directly, and didn't see if he could shoot it, Yu Fei directly put the black and blue iron bow into the system backpack, and then took out the throat sealing hand crossbow on his right waist, and his fingers were pulled one after another, and five crossbow arrows shot out quickly.

Zombies have a common weakness, that is, they only know how to attack, they don't have the slightest combat skills, they can't dodge, they can't defend, they will only charge forward.

So when fighting them, as long as you don't miss the shot, you don't have to worry about the arrows being dodged by them.

With a pop, the blue quality arrow hit the zombie's head first, and in less than two seconds, the other five crossbow arrows also shot at its head in one volley!

Six arrows instantly pierced its head into a hedgehog, and the zombie sound that had just been excited for less than two seconds stopped abruptly, and then fell straight to the ground!

"Whew, it's good, if you can't even hurt it with blue quality equipment, that's too bad!"

Yu Fei stepped forward to retrieve the arrow and dissect it.

The ability of this zombie is to fuse zombie corpses to enhance itself, as long as there are enough zombie corpses, it can become infinitely stronger, which is a relatively simple and crude ability.

The most difficult point to deal with with a fused zombie is when it is fused, when its body is almost liquid, and ordinary physical damage has no effect on it at all. But when it fused, everything was back to normal. And fused zombies only have the ability of 'fusion', which is relatively easy to deal with among high-level zombies.

The third-order zombie crystal nucleus is the size of a marble, and the system introduction also shows that it can only make antibody serum. Yu Fei immediately lost interest in it, threw it into the system backpack, and waited until the mission was over to see what good things could be exchanged.

The night is thick, and Yu Fei is in full swing.

A tiger bone soul breaking knife has become a life-seeking knife for zombies. Yu Fei stood at the entrance of the alley, facing the underground parking lot, and the zombies inside and the surrounding zombies were frantically rushing towards this side, and then were ruthlessly killed by Yu Fei.

After knowing that the split zombies had terrifying splitting abilities, Yu Fei came up with the idea of breeding them. After all, the most suitable living environment of the creatures can be simulated in the breeding garden, and the zombies do not need food, only the zombie virus can survive, so it is very feasible to breed them in the breeding garden.

But when Yu Fei caught the split zombies into the breeding park, he was rejected by the system and couldn't breed zombies!

Yu Fei couldn't help but feel lost, if he could breed zombies, then he would be able to have endless soldiers, and then he would directly dominate!

It's a pity that the system refused, and Yu Fei's idea of hegemony was directly shattered.

However, Yu Fei was not discouraged at all, since he couldn't get it, then he would destroy them!

Yu Fei is a battle maniac, when he is tired of killing and his energy is exhausted, he will return to the Truth Township to rest, and when he recovers, he will continue to fight!

After a full five hours of fighting, Yu Fei killed all the zombies in this area, and no more zombies came out of the underground garage!

Looking at the zombie corpses under his feet that had been dissected into pieces, Yu Fei expressed his satisfaction.

In the five-hour battle, Yu Fei didn't know how many 0-order zombies he had killed, it was too many to count, and 26 first-order zombies were killed, and 2 second-order zombies were killed.

The number of Tier 0 zombies here is too much, and the number of zombies above Tier 1 is too small, and Yu Fei doesn't know why this happens.

Tonight's battle is over temporarily, and Yu Fei is very tired.

The leather armor and bamboo royal combat uniform on the body are no longer intact, and the whole body is covered with zombie bite scratches! The antibody serum that could have allowed him to resist the attack of the zombie virus for 24 hours was only able to last for 3 hours when Yu Fei was crazy and injured, but fortunately, Yu Fei found out that his body was abnormal in time, and quickly bought a new bottle of antibody serum to drink, otherwise he would become a zombie!

The so-called wealth and danger are sought, and after going through dangers, they can grow rapidly, and after the First World War, Yu Fei's various abilities have also increased!
