The two of them came to the corpse of the Dark Moon Demon Wolf and took out the magic crystal in its body. Then he immediately felt the temperature around him drop rapidly, and a layer of white mist appeared in Ouyang Yu's palm.

The magic crystal, the aura crystal in the body of the demonic beast, is equivalent to the cyclone in the human body. The more high-level the Demon Beast, the more powerful and pure the Demon Crystal Aura in the body is, but it will be more difficult to refine.

The Shard can also be used to mount a weapon, giving the weapon the same bonus as the Shard stats. For example, this fourth-order ice-type attribute magic crystal, if it is embedded in the weapon, it can make the weapon also have an ice-type attribute. However, a weapon cannot be inlaid with magic crystals with the attribute of restraint at the same time, otherwise it will bring serious damage to the weapon, and even backfire on the person who uses the weapon.

When refining some elixirs, magic crystals are also needed as materials, and the value of magic crystals is huge. On this continent, there are countless strong people who fought for a high-level magic crystal, and finally lost their lives.

Just because of the pure aura in the high-level magic crystal, as long as they can successfully refine it, they can make a huge breakthrough when their cultivation is bottlenecked. Therefore, those who take shortcuts, even at the cost of their lives, take it for themselves.

Because on this continent, the strong are qualified to survive. When a weak person dies sooner or later, and even lives more terrible than death.

"Brother Yu, it's a pity that this is a fourth-order magic crystal, otherwise your cultivation will definitely improve. Yang Xin'er said a little lost.

"It's okay, it's still very useful!" Looking at the magic crystal in his hand, Ouyang Yu knew that for Venerable Him now, the aura in it was no longer of much use to him. But he knew that the magic crystal would be useful in other places as well, so he decided to put it away first.

But where should such a cold magic crystal be placed? He looked all over his body, but couldn't find a suitable place.

"I'll keep it for you!" Seeing Ouyang Yu racking his brains like this and didn't know where to put it, Yang Xin'er laughed and said.

"Great, it's good to have you. Hearing Yang Xin'er say this, Ouyang Yu immediately relieved his burden, he knew that the former must have a way to deal with this magic crystal, so he handed the magic crystal over without hesitation.

Yang Xin'er took the magic crystal and smiled when she saw Ouyang Yu's curious gaze. She knew that the latter must be wondering how she was going to place this hot potato.

In order to satisfy Ouyang Yu's curiosity as soon as possible, Yang Xin'er immediately stopped being verbose. Then the jade-like palm flipped over, and the magic crystal immediately turned into a streamer of light and shot into her snow-white wrist. At this moment, a small lightsaber immediately appeared on her wrist, and the lightsaber also shone with golden light.

"What is this?" Ouyang Yu looked at this scene in amazement, and asked with a sense of relief.

"When Brother Yu has his own weapon, he will know the secret. The powerhouses on this aura continent all store items like this. Yang Xin'er looked at her jade arm and said to Ouyang Yu.

After seeing Yang Xin'er's weapon, Ouyang Yu's heart couldn't help but stir, and when he thought that he could also have a weapon in the future, he couldn't help but become more and more interested in exploring the continent.

At this time, Ouyang Yu suddenly thought that Yang Xin'er's lightsaber was somewhat similar to the lightsaber he had condensed when he fought against Yang Feng last time. The only difference is that his own one is pure and transparent, without any impurities, and Yang Xin'er's one seems to have a golden light.

"Little fairy,. Let's keep going!" he didn't want to think about it anymore, he knew that the puzzles would be solved as he grew. The most important thing now is to get to the Tower of Babel as quickly as possible.

The two no longer hesitated, and immediately walked side by side towards the front entrance. The entrance was obscured by tree branches, and there was not a glimmer of light in the cave. Since they had just encountered the Dark Moon Demon Wolf, they knew that there might still be a magical beast hidden here, so they raised their vigilance.

After traveling in endless darkness for about half an hour, they did not encounter the monster again. Ten meters in front of them, there was a ray of sunlight in the transmission, as if the exit was ahead. The two continued on their way, and just as they were about to reach the entrance of the cave, they looked at each other and stopped.

At this time, Yang Xin'er waved her jade arm, and an aura barrier immediately appeared around the two of them, blocking their aura from the outside world.

"Brother Yu, now that we can go out, as long as we don't encounter demonic beasts above the fifth order, we won't be discovered by them. Yang Xin'er said.

"It's still my little fairy who thinks about it thoroughly, and it's safe and secure to have you by your side. Ouyang Yu took Yang Xin'er's hand and laughed.

Holding Yang Xin'er's slender snow-white hand, it was as comfortable as pinching a piece of fine warm jade, and the satisfaction in Ouyang Yu's heart was all written on his face at this time. On Yang Xin'er's delicate face, a girl's blush had already emerged at this time, but it could be seen from her expression and eyes that she was very happy at this time.

The two walked out of the cave hand in hand, as if they had returned to the old days. A blinding light followed, and both of them couldn't help but cover their eyes with their hands because they had been in darkness for a long time.

As they got used to it and put their hands down, they were amazed by what they saw.

At this time, they were in the middle of two mountains, one that had been split by an axe to be specific, and now they were in the middle of this chasm. What shocked them even more was that there were so many demonic beasts here, whether it was on the ground or in the air, and even the cliffs on both sides were full of bird-shaped demonic beasts, which was simply encountering the tide of demonic beasts.

"Little fairy, there are so many demonic beasts here, thanks to you for isolating our breath, otherwise it would be troublesome. Although Ouyang Yu had thought that there would be many demonic beasts here, he didn't expect that there would be so many, and at this time, he couldn't help but smack his tongue secretly.

"Fortunately, they are all low-level magical beasts, as long as we pay a little attention, they will not be able to detect our existence. Yang Xin'er closed her beautiful eyes tightly, sensing the breath of the demonic beasts around her, and then said with a sigh of relief.

"In that case, let's kill some demonic beasts and collect some demonic crystals!" Hearing that all of them were low-level demonic beasts here, Ouyang Yu suddenly relaxed a lot. Suddenly, his eyes lit up, and he thought of the magic crystals in the bodies of these demonic beasts. Although the magic crystals of these low-level demonic beasts did not have much effect on his cultivation, it was also good to be able to sell some gold coins, you must know that it was difficult to walk on this continent without money.

"No, it's not a problem to kill these low-level demonic beasts, in case you attract high-level demonic beasts, it will be troublesome. Seeing that these demonic beasts are gathered here on such a large scale, I estimate that there should be a high-level demonic beast that leads them here. After listening to Ouyang Yu's words, Yang Xin'er immediately denied his thoughts.

"Oh, okay, then it's up to you!" Seeing that so many prey couldn't be beaten, Ouyang Yu at this time was like, when he was about to eat his favorite food, someone suddenly told him that it was highly poisonous. Although he was a little reluctant, he was not the kind of reckless person after all, and reason made him clearly understand this.

The two stopped talking and walked straight towards the group of demonic beasts. Just as he entered the herd, Ouyang Yu raised his vigilance. Constantly sensing the aura emanating from the demonic beasts around him, to see if there is any danger. It's not that he doesn't have confidence in Yang Xin'er's aura cover, but he likes to do everything to prepare for the worst, and he won't be at a loss when the time comes.

At this moment, he frowned slightly, sensing that the aura of the demonic beast not far in front of him fluctuated greatly. At the same time, Yang Xin'er also felt something strange. The two of them looked at each other, nodded and walked towards the place in front of them that emitted a strange aura.

They came to a rather spacious clearing, and above this clearing, a group of demonic beasts were fighting each other. The scene was extremely bloody and spectacular, and both of them on the edge of the clearing could clearly sense the violent shaking coming from the ground.

There are roughly two kinds of magical beasts that fight, namely the Mighty Ape and the Human-faced Spider. At this time, the mighty ape suddenly jumped up, and its fist the size of a hammer smashed directly into the human-faced spider. The human-faced spider did not dare to slack off, and immediately swept out of its mouth with black lines, and then quickly dispersed around the wild ape, trapping it firmly in it, like a spring silkworm making a cocoon.

The wild ape was not so easily trapped, and after a sudden long roar, its body doubled in size at this moment. When the black silk mesh was about to be broken by its huge body, another layer of black silk covered it.

At this moment, the wild ape's feet slammed on the ground, and the ground immediately trembled violently, and then a depression appeared, and the wild ape also burst into the void at this time. After being pulled so violently, the black silk finally couldn't withstand such a big tearing force, and finally cracked open.

The wild ape, which had lost its restraint, rolled directly, and its fist like a giant peak slammed directly into the face door of the human-faced spider. Suddenly, a huge pit immediately appeared on the ground, and the human-faced spider in the pit had already been shattered, and a magic crystal rushed straight towards Ouyang Yu like a streamer.

Ouyang Yu reached out to catch it, then pursed his lips and looked at the magic crystal in his hand and laughed. Thinking that after working hard for a long time, he actually made a wedding dress for himself, an outsider, and couldn't help but cast a sympathetic look at the wild ape.

After about a quarter of an hour, the battle in the clearing was over, and in the end it was the mighty ape who won. At this moment, a wild ape, taller than the others, kept pounding its strong chest with its fists, as if to announce that it was the king of the place. The demonic beasts around them trembled and fled in all directions.

The two continued on their way, and an hour later they came to a cliff with no top in sight. was blocked by this cliff, and had to stop.

At a glance, I saw that there were many large and small circular potholes on this cliff. They guessed that there must be a hole in it that led to the outside world. So the two of them planned to find two holes at random first, and directly stepped on the ground with both feet, and flew towards one of the holes in the cliff.
