This time, Yu Fei felt that the cold breath was very tight from him, and the moment he found the cold breath, Yu Fei's body rushed out, rushing straight towards the cold breath. The cold aura felt Yu Fei chasing after him, as if he was frightened, and rushed towards the outside of the main hall at great speed. Seeing Yu Fei's body chasing out, Wu Chang followed closely behind, and at the same time controlled the blood droplets to slash towards the place where the cold aura emanated.

At that moment just now, Wu Changxiao also felt this cold breath, but it was not as sensitive as Yu Fei, it was just a matter of a moment! For a while, the three breaths chased directly to the door of the main hall, and the cold breath felt the breath of Yu Fei and Wu Changxiao fluctuating behind him, and he looked extremely flustered, and slammed into the door of the main hall. Just as it was about to rush out of the main hall, suddenly a sharp aura flew towards it at great speed, slashing at the cold breath, and in an instant, an extremely terrible scream came out.

Hearing the terrible scream, Yu Fei and Wu Changxiao's bodies couldn't help but shudder, because the scream was so weird that they couldn't hear the screams of people at all, and they didn't look like the screams of people! As this scream fell, the door of the main hall was slammed open, and the cold breath rushed out of the main hall directly. After the cold breath rushed out of the main hall, two figures fell to the door of the main hall, and these two figures were Yu Fei and Wu Changxiao, who were chasing after them.

Yu Fei looked at the outside of the main hall and frowned, he didn't expect the speed of that thing to be so fast! Even with the speed of the two of himself, he couldn't catch up at all! I thought that by grabbing that thing, I would know the cause of the corpse transformation.

Just when Yu Fei was annoyed, Wu Chang's voice sounded on the side: "Brother Yu, look at the bloodstains!"

Yu Fei looked in the direction of Wu Chang's finger, and suddenly saw a pool of blood on the ground, but the blood stain was dark gray, exuding a strange aura fluctuation, which was extremely weird. Looking at the blood stains on the ground, Yu Fei's brows furrowed tightly, he had never seen this thing before, even in the Nether, he had never heard of this kind of thing.

Just as the two of them were studying the pool of blood, a faint roar came into the ears of the two, and hearing this faint roar, Yu Fei and Wu Changxiao's expressions changed slightly. Looking at the outside of the main hall, I faintly saw dense figures rushing towards the main hall. Seeing this scene, Yu Fei's expression sank suddenly, I am afraid that it was the cold and miserable cry just now that attracted these walking corpses. Yu Fei remembered that the last time was after the cold aura suddenly appeared, and those corpses would undergo corpse transformation.

He didn't bother to carefully study the origin of this thing, and shouted at Wu Changxiao on the side: "Go! Get out of here! If we drag it down here, we both have to explain it here!"

Hearing Yu Fei's words, Wu Chang nodded his head, and the two of them directly swept away and rushed towards the valley they passed by when they came. As the bodies of the two rushed towards the place where they came, the walking corpses on the ground also followed the two behind the buttocks of the two, and there were many golden immortal-level walking corpses that kept jumping towards the two. Yu Fei's eyes sank, the level of jumping corpses is much more powerful than that of walking corpses, and the level of these corpses is constantly getting stronger! If they are promoted from jumping corpses to flying zombies, I am afraid that the two of them will not be able to leave today!

Not long after the two of them rushed out of the main hall, the dense walking corpses had all surrounded the two of them, and the number of these walking corpses had reached at least tens of thousands. And now the two of them are still some distance away from the exit of the valley, even if the two of them kill out, it will not be too easy! Yu Fei quickly thought about countermeasures in his heart, and at this time, several aura fluctuations suddenly appeared, and the sight of the two of them.

Feeling these few aura fluctuations, the two of them looked into the distance, and when the two of them saw a few figures not far away, the two of them suddenly took a breath of cool air! Although the aura fluctuations on those figures were only at the level of a golden immortal, their bodies flew straight towards the two of them. Seeing these three flying corpses, the flying posture was extremely weird, Wu Changxiao couldn't help but shiver all over his body, looked at Yu Fei and said, "Brother Yu, are these flying corpses still corpses?"

"Zombies!"

"Zombie?" Hearing this unfamiliar word, Wu Changxiao was slightly stunned.

Yu Fei nodded and continued: "In our place, zombies like this one are basically invulnerable! It's hard to kill! I just don't know ...... these three zombies right now."

Wu Changxiao couldn't help but smash his mouth when he heard Yu Fei's answer.

Before the two of them could speak, the three zombie breaths quickly approached in front of the two of them, and feeling the fluctuation of the aura full of corpse energy, Yu Fei stabbed out with a fierce shot in his hand.

Immediately after that, there was a sound of gold and iron fighting, and hearing the sound of today's fighting, Yu Fei looked up suspiciously, but saw that his spear was tightly pierced a distance from the tip of the spear, and it was not completely pierced. Sure enough, although the body of this zombie did not reach that level of invulnerability, it was still extremely terrifying! Yu Fei released the breath fluctuations on his body, and the other two zombies attacked Yu Fei fiercely, feeling the movements of these two zombies, Yu Fei directly withdrew and retreated.

At the moment when Yu Fei's body just retreated, the blood droplets slashed towards the two zombies with an incomparably sharp aura, and the blood droplets slashed into the bodies of the two zombies, making a crisp sound, and were directly bounced out. And on the chest of the two zombies, only a scar less than a finger deep remained. Wu Changxiao on the side couldn't help but be stunned when he saw this scene, he didn't expect this corpse to be so strong.

"Old Wu, something is wrong with this corpse! I'm afraid it's not a zombie, it's a corpse puppet!" Yu Fei, who had retreated, took the time to shout.

"What?" Hearing Yu Fei's words, Wu Changxiao's expression changed slightly. Corpse puppet? In an instant, Wu Chang's spiritual sense spread out, and Wu Chang's spiritual sense couldn't help but spread out, and Yu Fei's spiritual sense also spread out. The corpse puppet is here, and I'm afraid the mysterious man will be here too!

Yu Fei didn't have the slightest intention of fighting, and directly released the corpse he had subdued, it was the corpse covered by black armor, Yu Fei also gave him a well-known name, Drought Fish! As soon as Drought Fish came out, Yu Fei gave him an order to drag them to the three corpse puppets, and after getting Yu Fei's order, Drought Fish rushed directly towards the three corpse puppets and fought together.

Relying on his incomparably strong defensive ability, the three corpse puppets of the late stage of the Golden Immortal were hardened, and the four figures bombarded each other for a while, and they couldn't tell the winner from the loser. Seeing this scene, Yu Fei hurriedly said to Wu Changxiao: "Go! This place is not suitable for a long time!"

The three corpse puppets were dragged by the drought, and the remaining walking corpses were no match for the two at all, and soon the two of them killed from the many walking corpses, and their bodies turned into two long rainbows and flew towards the mouth of the valley at high speed. Just when the bodies of the two of them had just flown to the mouth of the valley, suddenly a terrifying aura fluctuation came, and Yu Fei looked at him with a puzzled face. The place where the breath fluctuation came from was the place where the corpse of the snake-shaped demon came!

Yu Fei groaned slightly and flew directly towards the place where the aura fluctuations came from, he wanted to see what caused such strong aura fluctuations! But to be careful, Yu Fei and Wu Changxiao both completely restrained their own aura fluctuations and quietly approached the valley.

After coming to a stone at the place of the valley, Yu Fei and Wu Changxiao's bodies hid behind the stone and looked down the valley. Suddenly, a figure covered by a black robe appeared in front of the two of them. Seeing this figure, Yu Fei's brows furrowed slightly, the mysterious person? Sure enough, here! I saw that the mysterious person was standing next to the pool, and the terrifying aura fluctuations emanated from the pool.

Yu Fei frowned slightly, they were far apart, and the two of them didn't dare to release their spiritual sense for fear of exposing themselves, but with the naked eye, they couldn't see what the mysterious person was doing at all! Just when Yu Fei was about to touch his brow and was about to leave, Wu Changxiao on the side suddenly grabbed Yu Fei: "Brother Yu, this guy doesn't seem to be the one who chased and killed us!"

Hearing Wu Chang's words, Yu Fei's body paused suddenly, and he turned his head in surprise.
