Just after Wu Wei had fled for a few breaths, another Extreme Flame Beast roared angrily and leaped out of the cold pool. The beast's appearance was similar to that of the fire beast, but its features were more pronounced, and its size was hundreds of times larger, like a small mountain.

The body of the Extreme Flame Beast is a python on its back, with a whole row of sharp spikes three feet long growing on its spine, like sharp knives, two long fins under its abdomen, extending to the end of its tail, and at the same time, it exudes a fiery red glow all over its body, and there are raging flames between its mouth and breath.

After jumping out of the water, it first sniffed in the vegetation for a while, and when it found that the carefully guarded Yanlong Fruit had actually been uprooted, its big copper bell-like eyes suddenly lit up with monstrous anger.

"Roar"

The Extreme Flame Beast let out an earth-shattering roar, and the sound completely shook the entire cave underground, and it followed the breath left by Wu Wei, and its body leaped into the cave crack with a murderous aura.

"It's not good, it's coming..."Wu Wei, who was fleeing, heard this earth-shaking roar, and he didn't feel a chill in his heart.

In less than a moment, a powerful Qi Dan Realm aura roared in from the crack behind him, and Wu Wei only felt a chill behind him, and he drilled forward lifelessly.

"Stinky boy... It's a big game now..."The old man of the Yin Spirit looked complacent, as if he was gloating about the taste.

Wu Wu's face sank, and he said coldly: "Dead old man, don't hurry up and think of a way, you also wait to become the thing in its belly!"

The old man didn't seem to be flustered at all, it groaned slightly for a while, as if talking to itself, "Those fire beasts in the molten should be the cubs of these two extreme flame beasts... The production capacity is amazing, it's incredible..."

"I don't have time to listen to you tell nonsense stories now..."Wu Wei only felt that the souls behind him were rising, already like ants on a hot pot, and at this moment, seeing that the old man of the Yin Spirit still had the leisure to figure out this, he couldn't wait to beat it.

"Stinky boy, this trouble can't be solved, how can you survive in the more cruel cultivation world in the future..."

Wu Wei seemed to know what the old man was going to say next, and before he could finish speaking, he quickly interrupted, "Okay... You'd better shut up..."

Suddenly remembered the previous few swishing attentions, this time it was finally awakened, relying on others is better than relying on oneself, the angry roar was already less than five feet away from him, and the strong bloody and murderous aura made people's hearts panic.

"Huh, I'm back here..."In a panic, Wu Wei found that he had actually returned to the cobweb-like cave passage where he was before, thinking that he should have returned to the ground.

He didn't have time to think too much, he suddenly stopped his body, and then quickly attracted his spiritual power, and with a wave of his hands, he ingested the remaining molten lava on the rock wall, and quickly set up a simple formation behind him.

Then he quickly turned around and drilled into the cave passage on the other side, and every time he flew to a turning point in the passage, he casually arranged a small defensive formation, and said in his heart: "Although the formation is not very powerful, it should be able to temporarily block the pursuit speed of the Extreme Flame Beast." ”

Sure enough, after a few turns in this labyrinth-like cave passage, the breath of the Extreme Flame Beast behind him gradually moved away.

After a while, Wu Wei stopped at the corner of a cave passage, and his divine sense radiated to investigate the formations he had set up, and it was obvious that those formations that had been arranged casually were quickly broken one by one, and he was not surprised by this, the Extreme Flame Beast was in the realm of Jiedan, and this small defensive array was completely useless.

After a slight groan, he quickly flew towards the entrance of several passages where there was no thought array, his body was as fast as lightning, but the speed of the Extreme Flame Beast was not slow.

Not long after Wu Wei left, the Extreme Flame Beast also stopped abruptly where Wu Wu had just stood with its bloody mouth open, it exuded a fiery red glow all over its body, its angry eyes were gloomy and hideous, and after two drops of dripping for a while, it suddenly turned around and chased towards the cave passage where Wu Wu had disappeared.

This Extreme Flame Beast is not only powerful in the realm, but also extremely intelligent, it inhabits this molten ground and does not know how many strange medicines and strange fruits it has swallowed, judging from the aura it emits, its cultivation has not only reached the realm of the Jie Dan but also has a steady tendency to develop towards the later stage of the Jie Dan.

Wu Wei rushed left and right in this labyrinthine cave, and he didn't know how long it had passed, but at this moment he was panting and standing at the entrance of a cave holding on to the rock wall.

Almost all the holes where the formation could be arranged were arranged, but such a directionless escape suddenly fell into a dead loop, and the Extreme Flame Beast was temporarily delayed by the formation to slow down the speed of the pursuit, but the fierce monstrous aura was far from being heard.

"Time should be enough. A hint of fierceness flashed in Wu Wu's eyes, the reason why he took great pains to lay out a small formation to intercept the pursuit of the Extreme Flame Beast was to prepare for a larger formation at this moment.

He didn't hesitate, sat down cross-legged on the spot, and in a moment of calm, he waved his hands to ingest the residual molten slurry from the rock wall of the karst cave as a formation 'rune', one, two... Soon, he condensed hundreds of fire-type runes, which floated in front of him, and then quickly condensed the spiritual power and laid down an invisible spiritual power light shield, which condensed almost half of the spiritual power in his body, and suddenly felt that his body was sluggish, but he still gritted his teeth and persevered.

"Enlightenment"

About a stick of incense time, with a loud shout, an invisible spiritual power light shroud quickly took shape at the mouth of the cave passage in front of him, and then his hands changed, and quickly triggered the fire system 'runes' to be printed on the light mask one by one, and the light mask brightened up impressively, it was obvious that Wu Wu's control of the runes had now reached the point of perfection.

It's a long story, and the time for arranging it is only the time of a stick of incense, and the fire attack formation arranged this time is completely an attempt after his temporary idea, and the time is even more rushed, but fortunately, the arrangement is successful.

"I don't know how powerful this attack formation is..."

Although the formation was successfully arranged, he did not have the slightest confidence in his heart, and he could only pray in his heart that this Extreme Flame Beast would be much weaker than the monk, although the gap between the Jiedan Realm and the Foundation Building Realm was only a realm, it was an insurmountable gap.

Just when Wu Wu's thoughts paused, the Extreme Flame Beast leaped murderously, and the behemoth with a body as high as three zhang suddenly stopped in front of the fire attack formation that was three zhang away from Wu Wu.

It roared at Wu Wei with its scarlet mouth open, as if it was demonstrating, and at the same time, its hideous eyes looked around the cave passage for a while, as if it had discovered the existence of the formation in front of it.

"What a clever monster..."

Wu Wei forcibly stabilized the shock of his mind, and sacrificed a black short sword to levitate in front of him, the aura of the Extreme Flame Beast was extremely terrifying, even if he was far away, he could feel the Lingtai Divine Soul fluttering under the deterrence of this powerful breath, which was a kind of realm suppression and deterrence.
