The use of the beast heart is relatively simple, the storage energy of the low-level beast heart is small, and it is generally a material for arranging low-level formations, although it can absorb energy from the beast's heart to improve its own cultivation, but the rich people also use spirit stones for cultivation, which causes the single use of the beast heart.

The magic crystal produced by the Demon Beast can store more powerful energy, and it is also one of the materials used to arrange the advanced formation, which can absorb the energy in it to improve the cultivation, which is usually more expensive and scarce than the Spirit Stone, and can only be produced from the hunted Demon Beast, and the lowest level of the Demon Beast is comparable to the cultivation of the later level of the Spirit Master.

After Nangong Yunyao put the first-level beast heart in his hand into his pocket, he couldn't help but worry when he looked at the cattle corpse on the ground, frowned and worried: "How can such a huge corpse reasonably appear in the Li family tribe without revealing the secret, looking at this figure requires at least two beginner-level martial artists or one middle-level to lift it, and it is troublesome to carry it without birds and demon beasts!" ”

Then he sighed: "There are too many things needed at this stage, birds and monsters and space rings, but space rings are too expensive, and if they are taken out directly from the earth's space, it will be too easy to expose, hey!" ”

"Let's improve our cultivation first."

Immediately he was meditating in the space of the earth.

At this time, in the center of the earth's space, there is a fist-sized white crystal ball that is slowly rotating, seemingly without energy fluctuations, but it has silently transformed the surrounding sea water into a spiritual liquid, if a strong person finds such a dense spiritual liquid, I am afraid that they will be surprised, after all, the spiritual veins in the Xuanyun Realm have been relatively rare since the decline, not to mention the spiritual liquid that is so dense that the spiritual energy has turned into liquid.

However, no one knew about this cultivation treasure, even Nangong Yunyao, the owner of this place, who didn't know about it, after all, he had just descended to the sapphire blue water, and there was an enchantment to stop him.

At this time, there were roars of various animals on the grass ocean outside, as if they were close at hand, which made Nangong Yunyao, who had just arrived here for the first time, extremely nervous, but if it was a hunting veteran, he must be used to this roar, which sounded close in front of him, but it was far away, and the sound never stopped, every night.

After a while, hearing that the voice was not nearby, Nangong Yunyao took a breath and took a deep breath: "There are a lot of demon beasts here, and there must be many types, but I haven't encountered them, Muhai is so big, if you hunt for a long time, you will definitely encounter it." ”

After a long night, after the various roars of those demon beasts in the night, it was not far from the morning light.

The sky is brightening and the morning is dawning.

A trace of white light gradually passed from one side of Muhai to the other, and the roars of various demon beasts in the night gradually quieted down, ushering in the sound of the birds hovering in the sky, heralding the arrival of morning.

In the boundless sea of grass, in an artificially dug underground cave, a young man about 15 years old is stretching his waist, his eyes are staring at the entrance of the cave.

He blinked his bright eyes and said, "Hey! Finally stayed up until morning, and when it was time for me to pretend to be forced, the cultivation of the first level of martial arts was not a problem to deal with first-level demon beasts, and if the shooting accuracy of the bow and arrow was improved, the efficiency would be much higher. With that, he crawled out of the cave and stood in the grass.

Nangong Yun looked at Mu Hai in front of him, and then walked towards the inner wall.

And this trip was more than a day, during which he only captured a few ordinary beasts, and did not encounter demon beasts, which made him very disappointed.

Looking at the avenue not far ahead that separates the sea of grass in half, Nangong Yunyao also showed a smile on his face, and said in surprise: "I finally arrived at the inner border known as the 'taboo zone', this walk is a day, and there is no harvest during the period, I hope this inner circle will give me a big surprise!"

After walking for a while, you will arrive at the dividing line between the inner perimeter and the periphery, a boundless avenue separates the inner perimeter from the periphery, and there is a large stone tablet on the side of the road not far away, and the monument is nothing more than the warning words such as danger and not entering.

A wicked smile appeared at the corner of his mouth, and he hummed softly: "Uh-huh, let's go to the prey!" "After that, one foot stepped into the grass in the inner perimeter, like the embodiment of an adventurer, with high risk and high return.

The scene after stepping into the inner enclosure is also different from the periphery, first of all, the inner enclosure is a little damp, not as dry and sturdy as the periphery, and the grass in the inner perimeter is taller, and it is difficult to see the light of day after entering, and you can only identify the prey by ear.

After walking for a while, he didn't see the prey, Nangong Yunyao had a little loss in his eyes, and he couldn't help but retreat in his heart, and wondered: "Isn't it rumored that there are many demon beasts in the inner perimeter?" Could it be that he is going in the wrong direction? ”

But the huge profits in his imagination forced him to walk forward, if he retreated, how could the goal of buying birds and monsters be achieved, could it be difficult to wait for the ancient banyan seeds to blossom and bear fruit? Obviously, this is not the result that Nangong Yunyao wants!

As I walked, the ground became more and more wet, and I could even step on water, and there was a lot of mud stuck to my feet, and the grass was greener, and I complained a few times, and my emotions were mixed with a little sadness.

However, after not taking a few steps, Nangong Yunyao's sad mood also became happy, a pair of eyes were bright, and he saw a small pool in front of him, about dozens of square meters in size, the water in the pool was green, and there were many animal footprints on the edge of the pool, which were all traces of prey!

I was also satisfied: "Well, not bad! In the end, I was not disappointed, persistence is victory, but fortunately I didn't give up. ”

Then he touched the feces left by the animals on the ground, pretended to dig a little with his hands, and felt a little hard, and could only draw a conclusion that he had been gone for a long time.

"I finally have some expectations, maybe there's a bigger lake in there!" After that, he left the pool and walked towards the inner perimeter, without worrying about anything, after all, he couldn't reach the depths of the forbidden area for more than a month.

Suddenly, there was a fight between two beasts in front of him, Nangong Yunyao stopped, squatted on the ground with all his attention and pricked up his ears to listen, he could vaguely hear the horns of the two beasts colliding, and estimated the appearance of the two beasts in his heart, and walked towards the sound step by step, expecting it to be a demon beast.

The further you go, the more intense the battle of the horns becomes, accompanied by howls and crashing sounds, especially the sound of "bang, bang", just by hearing this sound, you can imagine the hardness of the horns, as if they were indestructible.

Nangong Yunyao cautiously touched the grass along the grass, and what caught his eyes was that two demon beasts were fighting with two horns, and there was no disadvantage at present, one was a huge herding cow, and the other was a two-horned cow with curved thick horns, although it was only the size of a buffalo, but it was not inferior at all.
