After dealing with the mutant beast, the sea of corpses moved again, sweeping towards the depths of the zoo like a black wave, and the two zombie troops separated by Xia Feng also completed the entrapment of the zoo, and the boundless sea of corpses formed a huge encirclement, completely isolating the zoo from the outside world.

"This ...... How can there be so many zombies here? Shifang stood on the tree, looking into the distance, his mouth was big, and he said with a look of disbelief.

Although there was no expression on his face, the drastically narrowed blue pupils could still see the unrest in his heart, and he stared at the sea of corpses for a long time before he slowly spoke: "Withdraw!" The mission was hopeless. ”

"The prophet ......" Shifang looked a little hesitant.

"If the prophet knew that there were so many zombies here, he wouldn't blame us, you see these zombies, there are at least hundreds of thousands, no matter how powerful your divine arrow is, how many can you kill." Eclipse Han looked at the sea of corpses pressed by the black, his eyes full of fear.

Shi Fang smashed his fist on the trunk of the tree with some unwillingness, and said through gritted teeth: "It's really unlucky, there are so many zombies, it is estimated that none of those evolution beasts can escape, and they have run such a long way in vain." ”

"You should be glad that if we wait until we get to the zoo and encounter these zombies again, it's not just the evolutionary beasts, we both have to be planted here." Eclipse Han is very satisfied.

"Alas! It's a disappointment, let's go, let's go back now, maybe we can make it to dinner. ”

Shifang sighed, jumped down from the tree, turned around and walked back the way he came, Eclipse Han glanced at the sea of corpses again, and then turned to leave.

Xia Feng didn't know that his move of mobilizing zombies to form an encirclement scared away the two top abilities, and at this time, he had already followed the sea of corpses to the depths of the zoo, standing in front of the colorful spiritual veins.

Beside him, there were hundreds of second-level zombies and two power-type third-level zombies, all of which were advanced zombies after devouring the flesh and blood of mutant beasts, although more than a dozen mutant beasts killed tens of thousands of zombies, but they also raised the high-level combat power of the sea of corpses to a higher level.

The vein in the zoo is much larger than the one in the school, and the highest peak has reached a height of seven or eight meters, so it is not impossible to say that it is a real mountain range.

At the top of the mountain range, there is a giant bird's egg, which emits a faint multicolored halo in the sunlight, and a peacock can be faintly seen around the egg.

"Is this going to be advanced?" Xia Feng looked at the giant bird egg in front of him and said in disbelief.

Think about himself, he worked hard to find the spiritual vein, ate strawberries and killed mutant beasts, and tossed in the secret realm to reach the peak of the third level, but this mutant peacock, since the end of the world to the present, has been squatting in this zoo, and he is about to be promoted to the fourth level, and his back molars are really going to be crushed.

It's no wonder that those mutant beasts just now fought to the death one by one, and it turned out that they were all delaying time for the mutant peacock to buy enough time for it to advance.

However, since it had not yet completed its advancement, Xia Feng naturally would not wait for it politely, holding Zixiao in his hand, he raised his leg and stepped on a raised boulder in the spirit vein, jumped over, and smashed it towards the bird's egg.

"Zheng!"

Zixiao landed on the bird's egg, making a piercing sound of gold and iron, and a huge anti-shock force came down his arm, directly sending Xia Feng out and falling heavily to the ground.

As a third-level zombie with rough skin and thick flesh, it was completely painless and itchy to fall, Xia Feng gently supported it with his arm, and then stood up cleanly and looked towards the bird's egg.

The egg that the mutated peacock turned into was unexpectedly hard, and his blow not only contained its own strength, but also had the blessing of the God of War bracelet, but he failed to break the bird's egg, and not even a crack was left.

"This bird's egg can't be beaten with iron, it's so hard, I still don't believe it, I really can't break you."

Xia Feng gritted his teeth and roared in his heart, clasped Zixiao with both hands, and smashed towards the bird's egg again, with another loud bang, Xia Feng flew out upside down again and smashed to the ground.

And the bird's eggs are still intact, but the peacock phantom on the surface is flying more cheerfully, as if it is mocking Xia Feng.

"Master, no, let's retreat first! I see that this mutant beast is about to complete its advancement, otherwise it won't be able to block your two attacks, and when it breaks out of its shell, I'm afraid we won't be able to escape. Long Xiang stood aside and whispered with his spiritual power.

"Run a fart, you can run over the winged one on two legs, blast me with the Polar Ice Cannon, freeze it for me, I want to see if it can advance without aura." Xia Feng pointed to the bird's egg and ordered.

"Master, you haven't seen the mutant beast advance before, and in the final stage, it is an inner transformation, and you don't need aura to be promoted, so let's run!" Long Xiang explained to Xia Feng, still trying to escape.

When Xia Feng heard this, he ignored Long Xiang's suggestion to escape, but ordered: "Then give me a bang, freeze it first, and call me Hades." ”

"Yes, Hades."

Long Xiang's life was in Xia Feng's hands, Xia Feng was reluctant to run, he could only stay here, obediently mobilize the zombies, and blast the eggs on the mountain peak with the ice cannon.

And Xia Feng walked straight to the side of the spirit vein, raised his palm, looked at the bird egg that had been covered with a layer of frost, and said secretly in his heart: "Today, I will see which of the two of us can succeed in the advanced level, lock the vein and swallow the spirit, swallow it for me." ”

The ink-black chains rushed out of the palm of his hand, flying into the multicolored stone wall of the spiritual vein, and the devouring power was released, and a huge stream of spiritual energy poured into Xia Feng's body along the chain.

With the influx of spiritual energy, the invisible barrier that blocked Xia Feng's advancement reappeared, but at this moment, with the supply of a whole spiritual vein, this invisible barrier was no longer so impregnable, and under the impact of a stream of spiritual energy, it gradually began to loosen.

And when Xia Feng devoured the spiritual veins, the colorful halo on the bird's egg became more and more dazzling, and the peacock phantom around the bird's egg became more and more condensed, and a faint coercion slowly spread out, as if announcing the birth of the king.

Just as Long Xiang said, the advancement of the mutant peacock has come to an end, once it breaks out of its shell, then Xia Feng and his subordinates will all feel the terrifying power of the fourth-level mutant beast.

Of course, if Xia Feng can be promoted to the fourth level with the help of the spirit vein first, it will be when the mutant peacock suffers a catastrophe, even if the defense of the bird egg is amazing, it will not be able to resist the attack of the fourth-level zombies.

And who can be one step ahead and advance first can only wait for the final answer to be revealed over time.
