To the west of Tiankeng Mountain is a wasteland.

The dazzling sunlight, the boundless yellow sand, the sporadic appearance of a few sporadic grasses, and the strange howling hurricanes seem to be like this for eternity.

Guo Yang half-squinted his eyes and looked into the distance, except for desolation, desolation.

He used his divine sense to probe and found that the yellow sand here contained a special mineral, which actually had the effect of isolating his divine sense. The power of Guo Yang's divine sense can be detected at most thirty or fifty zhang away.

"More than a thousand feet to the left, there are a small number of xenolizards. Seven or eight hundred zhang away from the right hand, there are more than 100 xenoborn lizards. Where to go?" said Azulu, sensing it.

"Let's find a few practice hands first, and see the strength of the xenosaurus. Guo Yang said with a deep groan.

The four of them flew to their left hand.

Far away, they saw seven or eight xenolizards, crawling leisurely in the yellow sand. Each xenobiotic lizard is about a foot long, its whole body is dark gray, and its whole body is covered with pimples and fine cracks.

"Xenosaurus lizards have extremely high defense, great strength and ferocity, and their only disadvantage is that they can't control the sky. Therefore, it is the easiest fourth-order beast demon to hunt in this mission. Aso said.

Guo Yang stepped on the five spirit boots and flew over cautiously.

The seven or eight xenolizards roared dullly, quickly crawled over, gathered under Guo Yang's feet, raised their heads upward, opened their bloody mouths, and revealed their sharp teeth.

Guo Yang smelled a disgusting fishy smell, and his mind was dizzy.

"Poisonous!" Guo Yang was slightly startled, took out a Wanqing Pill and swallowed it, which was relieved.

"Beware of lizard venom, everybody. Guo Yang turned around and shouted, popping up a small fireball in his hand.

There was a loud bang, and a small fireball slammed into the head of a xenosaurus. The xenosaur's body shook, but it didn't seem to be injured, and there was a small fist-sized pit on its hard forehead.

Guo Yang secretly wondered, the defense of this xenobiological lizard was indeed amazing.

Guo Yang experimented with the attack spells he had practiced one by one, but he couldn't hurt the xenolizards in the slightest, but he only angered these xenolizards, and they spun wildly in the yellow sand, roaring with their heads held high.

Aso and the other three also released spell attacks one by one, but they couldn't hurt the xenolizard.

Even, Asu also sacrificed a small golden flying sword, injected spiritual power, and shot at the neck of the xenosaurus like lightning, only piercing a small wound one or two inches deep.

After tossing for a long time, Guo Yang and the other four did not even kill a xenoborn lizard, but consumed a lot of spiritual power.

Guo Yang thought to himself: "I wonder if the little gray sword can break the defense of this xenosaurus?"

As soon as he thought of the little gray sword, he saw a faint gray light flashing, and a xenobiological lizard suddenly trembled, and it withered in a large circle visible to the naked eye, and then, after a few silent convulsions, it did not move.

Guo Yang was stunned for a moment, and said in his heart: "I just had an idea, and this little gray sword ran out by itself." ”

Asu and the others were also stunned, they didn't notice Guo Yang's little gray sword at all.

The xenosaurus had a small wound on its forehead less than a finger width, and not a drop of blood came out.

What's weird is that the flesh and blood essence of this xenosaur's body seems to be gone in an instant?

Only Guo Yang himself knew that it was done by the little gray sword. The moment it pierced through the xenosaurus, it sucked the flesh essence in its body empty!

Looking at the happy little gray sword in the spiritual sea, Guo Yang was surprised and delighted: "I knew that this little gray sword was a big foodie, devouring spiritual power is like drinking cold water, who would have expected this guy to devour all the flesh and blood essence." It's terrifying, isn't it?"

Guo Yang's mind moved, the gray light flashed, and another xenobiological lizard was devoured into a dry lizard!

Guo Yang himself was stunned, so he simply killed the remaining alien lizards.

Devouring the flesh and blood essence of seven or eight xenolizards, the little gray sword looked extremely cheerful, and there was a faint hint of light red on the pale gray sword body.

Asu, Aliu and Zhang Xiaopang were dumbfounded and looked at Guo Yang in surprise.

Guo Yang fell to the ground, squatted in front of a xenoborn lizard, and carefully investigated, and found that the xenoborn lizard had really become a dry lizard, and there was not a trace of spiritual power left in his body.

Guo Yang took out a pill and swallowed it, recovering slightly. The little gray sword is powerful, and the spiritual power consumption is not small.

"Let's go, find those alien lizards!" Guo Yang flew up and flew towards the hundred and ten alien lizards that Asu had said before.

Ah Liu honestly put the corpses of seven or eight xenoborn lizards into a storage bag, which was a proof of completing the task.

Guo Yang was still more than ten zhang away from the group of xenolizards, and the little gray sword suddenly shot out, and in the blink of an eye, twenty or thirty xenobiotic lizards were sucked into dry lizards.

By the time Asu and the three arrived, Guo Yang had already killed all the xenosaurs.

Zhang Xiaopang grew his mouth and couldn't speak for a long time.

Guo Yang's little gray sword is too perverted!

Ah Liu inhaled the cold air and put all the xenosaurus materials into the storage bag, he knew that Guo Yang was very strong, who knew that Guo Yang was even more fierce now.

Asu's eyes narrowed with laughter, and he said loudly: "Guo Yang, yes, with our efficiency, we should take on more beast demon tasks!"

Guo Yang smiled: "It doesn't matter, pick those beast demons that are easy to kill, and do it all along the way, and when you return to the sect, you can directly hand them over while handing them over." ”

Guo Yang's fortune quartet has cooperated many times, and they have already had a tacit understanding, needless to say, Asu quickly reformulated the route.

The four of them swept along the way, and Ah Liu didn't have time to pick up those materials alone. Zhang Xiaopang took the initiative to clean up the battlefield with Ah Liu.

In just ten days, Guo Yang and the others had already completed the task of the sect, and they also killed hundreds of other beast demons.

Guo Yang roughly calculated, with such efficiency, in another month, he could complete nearly 100 tasks, and by then, there would be hundreds of thousands of merit points.

And as a large amount of the flesh and blood essence of the beast demon was devoured, Guo Yang's little gray sword gradually changed.

The first is the size of the little gray sword, which expands a small circle.

The second is its color, which gradually turns from light gray to light gray, which is obviously condensed a lot.

In addition, the red filaments inside the little gray sword are also more obvious, faintly circulating, quite weird.

Guo Yang was a little worried, this little gray sword was so bloodthirsty, and he didn't know what it would become in the future.

"Ten years ago, the little gray sword would only cut off people's ears, but now I'm afraid you can't poke people casually, and if you don't get it, it will kill you. Guo Yang said with a wry smile.

As the four of them happily killed the beast demon, they slowly entered the inner area of Tiankeng Mountain.

When it came to the inner perimeter, the fourth-order beast demons were gradually rare, and the fifth-order beast demons were more and more.

Guo Yang cautiously probed and found that the strength of the fifth-order beast demon was really much stronger, if it was purely in terms of mana, it was much deeper than that of ordinary late-stage foundation building monks.

The strength of the fifth-order beast demon is basically between the strength of the monks in the foundation building period and the Jindan stage.

However, after all, most of the fifth-order beast demons' spiritual wisdom has not yet been civilized, and it is still relatively easy to deal with with with their innate spell power.

Guo Yang's little gray sword kills the fourth-order beast demon, just like cutting melons and vegetables, destroying the withered and decaying.

As for dealing with fifth-order beast demons, it was not so easy at first, and Guo Yang often needed to deal with it carefully.

"Kill these mosquito-billed beasts, and we'll have to go back. The front is too dangerous. Guo Yang looked at the swampy land, the group of mosquito-billed beasts the size of a head and mouthparts three or four feet long, and said.

Guo Yang is not greedy.

He knows how to do what he can and take what he sees.

"Good. I've planned the route back. Asu smiled slightly and said.

Those mosquito-billed beasts look weird, and their attack talent is that their mouthparts can be stretched out in an instant, and when Guo Yang first started to try, he was negligent and almost silently pierced the center of his eyebrows by a mosquito-billed beast.

Guo Yang broke out in a cold sweat.

Guo Yang swallowed an elixir, sacrificed a protective shield, and urged the Five Spirit Boots to fly to the extreme and flew towards the swamp.

Those mosquito-billed beasts that seemed to be stationary moved instantly, and in a low buzzing roar, they swarmed towards Guo Yang.

Guo Yang flew with all his might, cooperating with teleportation from time to time, and at the same time inspiring the little gray sword to shuttle through the dense herd of mosquito-billed beasts.

In an instant, more than a hundred mosquito-billed beasts that had been sucked dry of flesh and blood essence fell down.

Guo Yang flew and killed at the same time, slowly leading the group of mosquito-billed beasts to the outside of the swamp.

At the same time, the Five Spirit Boots and the Little Gray Sword were fully operational, so that Guo Yang's spiritual power was quickly consumed.

In less than a cup of tea, Guo Yang's forehead was sweating.

However, hundreds of mosquito-billed beasts were almost killed by the little gray sword, and there were less than a dozen left.

Guo Yang gritted his teeth and insisted, urging the little gray sword to shuttle quickly, and finally killed them all.

Guo Yang fell to the ground, took out two or three recovery pills, swallowed them all.

He sat on the ground, pale and a little prostrate.

Half an hour later, Guo Yang slowly opened his eyes, the previous fatigue was swept away, and most of his spiritual power was recovered.

"Fifth-order beast demons are not easy to kill. Each of them has its own difficulties. This mosquito-billed beast, if it weren't for its own extreme speed, don't provoke it if you can!" Guo Yang frowned and said.

"Fortunately, you are a thug, otherwise, we would not have dared to provoke these guys!" Aso laughed.

"Let's go. Go back. Asu, when you encounter a large group of fifth-order beast demons, try to avoid them. Guo Yang said.

The four of them hunted the beast demon while slowly returning back.

Twenty days later, several people left Tiankeng Mountain safely.
