Xia Yang knew that many people would definitely visit Lingyun Cave in the future, and it was because he chose the place where he buried Xuanyuan Yellow Emperor in the underground space where he suppressed Chiyou. This place was originally opened by Xuanyuan Yellow Emperor, and it is just below the mausoleum, hidden deep in the center of the earth, even if it is a peerless powerhouse, without the power of the Yuan Shen, it is impossible to easily find here, very safe.

Along the crack in the ground that the Tiger Soul Knife had broken before, Xia Yang spent a lot of effort to bury the bones of the Xuanyuan Yellow Emperor, and then carefully filled and smoothed the crack in the ground, erasing all traces before he was relieved.

After doing all this, he sat in the stone room for a long time before he said to Huo Qilin: "Xiaohuo, I'm leaving, but it's not safe in the outside world now, so you should stay here for the time being to take care of the mausoleum of your predecessors, and then come to pick you up after I have enough strength in the future to ensure your safety, how about it?"

The fire qilin had not been able to accept his new master for a while, and the two sides were full of strangeness. What's more, it has been living in this Lingyun Cave since it was born, and it didn't think about leaving, so after hesitating, it agreed to come down.

"Xiaohuo, after I leave, you remember to hide yourself, if someone comes in, you can hide, anyway, the bones of Xuanyuan's predecessors are no longer in the mausoleum, there is no need to fight with those people, you know?"

Xia Yang actually wanted to take the Fire Qilin away, but although it regained its senses, became very docile, and was able to restrain the flames on its body, it was difficult for it to appear in front of the world with its size. Especially since he doesn't have enough strength to protect its life now, taking it away will only do more harm than good.

The fire qilin nodded, signaling that he understood, and after being silent for a while, he suddenly raised his left claw to pierce the scales on the back of his right claw, and then squeezed out a ball of blood the size of a dragon's eye from it and handed it to Xia Yang.

Through the idea transmitted by the fire qilin, saying that its blood could improve his strength, Xia Yang couldn't help but feel a little puzzled when he saw it. With a complicated mind, he hesitated for a moment, but still took out the container from the storage space at the urging of the fire qilin and accepted the drop of qilin blood.

There was no way to repay him, so he could only take out a large amount of delicacies collected from other planes and modern times, and invite the fire qilin to eat it well.

The food that Xia Yang took out was all things that the fire unicorn had never eaten, it was extremely delicious, and there were all kinds of drinks, and the taste was also very good. After eating, it became a little closer to Xia Yang.

Feeling this intimacy, Xia Yang was also very happy, and simply took out all the food hoarded in his space, filled it with a small cave, and told it not to eat it with the package, before touching its head and saying, "Xiaohuo, all this food is left to you, but you have to save some food." When I come back next time, I'll be sure to bring you more delicious food...... You're going to protect yourself when I'm gone, you know?"

The fire unicorn's cheerful thoughts came, reassuring him that it would definitely take good care of itself.

Xia Yang said goodbye to it again and again, and after repeating his instructions, he forcibly endured his reluctance and turned around and left Lingyun Cave.

......

After leaving the Lingyun Cave, Xia Yang's mood could not calm down for a long time.

He came to Lingyun Cave this time, originally the main purpose was for Xuanwu True Skill, but he didn't expect so many incredible things to happen, with his extremely calm and unfazed martial arts heart, he still had a strong sense of shock.

Finding a no-man's land deep in the mountains and old forests, Xia Yang took out the dragon vein and the blood of the unicorn. The reason why he didn't take it in Lingyun Cave was because it was not peaceful there, and there might be uninvited guests at any time, and he didn't want anyone to find out about his existence and the Fire Qilin.

After being unsealed by Xuanyuan Yellow Emperor, he re-observed this dragon vein, and sure enough, he found a huge amount of energy in his spine, if there is no accident, this is the dragon yuan left by Xuanyuan Yellow Emperor.

From the memory of Xuanyuan Yellow Emperor, Xia Yang learned that this power of the dragon yuan was sealed from the body to the tail vertebrae before he sat in the flesh. Originally, when it was sealed, some of it disappeared naturally with the destruction of the physical body, and over thousands of years, more than half of it was lost, and now the remaining part of the power of the dragon yuan is less than one-tenth of the original complete dragon yuan.

However, Xuanyuan Yellow Emperor once calculated that the one he killed back then was the first ancestral dragon between heaven and earth, and its strength was much higher than that of the ancestral dragon descendant killed by Emperor Shi Tian in later generations. In other words, this is less than one-tenth of the power of the Dragon Yuan that has survived, and it is slightly more than one-seventh of the second-generation Dragon Yuan in the back.

But Xuanyuan Yellow Emperor, who had such terrifying power, actually fought with Chi You to the death, which can also show how terrifying the decisive battle between the two was at that time!

Judging from the original plot, although the second generation of dragon yuan is divided into seven, it is only one dragon yuan, which has the effect of immortality and eternal youth, and is stronger than the phoenix blood of Emperor Shakti. It's just that Xia Yang, who originally had the intention of seeking Long Yuan, now that the power of Long Yuan in this dragon vein is close at hand, he didn't have the slightest sense of excitement, but his heart was calm.

After all, this power of Long Yuan is too heavy, thinking of Xuanyuan Yellow Emperor's entrustment to him, how can he take it with peace of mind.

After pondering for a while, he came back to his senses, and his eyes became firm. Now that the power of the Dragon Yuan is already there, it is imperative to stop the Emperor Shakti from slaying the dragon!

Xia Yang understood that Xuanyuan Yellow Emperor wanted him to stop the dragon slaying, not just to ask him to stop a slaughter, so as not to exterminate the dragon race, but the dragon, as the top creature of this plane, and the head of the four great beasts, can be said to implicate the luck of the whole world.

In the plot, it is precisely because those ambitious people have obtained the extraordinary power of the true dragon that they have brought disasters to the world that should not have been, and even affected the Shenwu Era more than a thousand years later. If the dragon hadn't died, there's a good chance that none of these catastrophes would have happened.

Of course, Xia Yang is not blindly optimistic. After all, this matter involves the Heavenly Dao in the underworld, and no one can say whether it will cause more serious consequences, or whether it will return to the original trajectory after doing everything possible. What's more, going against the sky is never a simple thing!

Looking at the blood of the dragon veins and the unicorns in front of him, now the four major rui beasts of the dragon and phoenix and the turtle have all fallen, only the dragon and the unicorn have descendants surviving, and from the memory fragments of Xuanyuan Yellow Emperor, Xia Yang also learned about the characteristics of the four great rui beasts.

The four great rui beasts are all a combination of heaven and earth aura, and they all have an extremely large life element, that is, they have the effect of making people immortal.

The true dragon is mainly stronger than strength, and it is also the head of the four beasts, which is also the reason why the martial artist's skill has increased dramatically after taking Long Yuan.

The phoenix is stronger than the life force, and no matter how many injuries it suffers, it can recover quickly. Later, if it wasn't for Emperor Shakti's own death, if he used the five thunders to turn his hands into the effect of his phoenix blood, it would never have been possible to die in the hands of the broken waves.

The Qilin is mainly strong in terms of physique, that is, to enhance the human body and potential, which can make the warrior have a higher growth limit. It's just that the fire unicorn is still in its infancy, and it was eroded by the ferocious qi before, which affected the power of the bloodline, so it is not obvious in the plot.

As for the last dragon turtle, it is Xiao Sanxiao, who is stronger than Shouyuan and has taken the blood of the dragon turtle, and can be said to be the person who has lived the longest in the wind and clouds. In addition, the dragon turtle also has the effect of increasing wisdom, which can also be seen from him.

After understanding the characteristics of each of the four great beasts, Xia Yang did not hesitate, and directly sent the blood of the unicorn that the fire unicorn gave him into his mouth!
