Mu Hanyan thought about it carefully, although in the past tens of thousands of years, many legendary rare birds and beasts have disappeared, but according to records, there are still one or two legendary beasts from time to time, but the Rui beast has never appeared, this is obviously not normal, and there must be some reason.

"You have already experienced the divine power of the Rui Beast, how can such a divine beast be so easy to hatch? It is said that only by gathering the purest qi of heaven and earth can it hatch a rui beast. In ancient times, the qi of heaven and earth was rich and pure, so from time to time, Rui beasts would descend, but now the Qi of heaven and earth in the Holy Court Continent was too bad at that time, and it was impossible to hatch Rui beasts at all.

Even many alien beasts with the bloodline of Rui Beasts will run out of vitality during the long incubation process, and they will not be able to survive the moment they are born out of their shells. Mu Ruian explained.

Mu Hanyan suddenly realized, what Mu Rui said, she also experienced it personally, when she got this alien beast egg, its vitality was almost exhausted, Mu Hanyan tried to hatch it unconsciously, and was almost sucked out of vitality by it, and finally relied on the help of Star Fantasy Qianji and Ye Yanran to escape the catastrophe, and this alien beast egg was also resurrected by her vitality.

Thinking of the Star Fantasy Thousand Machines, Mu Hanyan suddenly thought of a question, why didn't he tell himself this kind of thing in advance, so that his life was hanging by a thread, and he himself couldn't wake up?

"So, this Rui beast egg is destined to be unable to hatch?" Mu Hanyan was a little disappointed and more sad, and said in a low voice.

Whether it is a rui beast or not, this beast egg was saved by her life after all, and from a certain point of view, it is connected to her by blood. Thinking back to the cute appearance of the little round egg jumping behind him, and then thinking that it will never hatch, and one day it will run out of vitality and die, how can Mu Hanyan not be sad?

"If it can be hatched, it will be hatched earlier, how can it wait until now?" Mu Rui'an also felt quite regretful, and continued, "If I guessed correctly, the existence of the poor temple and the poor bones is actually to protect this Rui beast egg, but unfortunately, ten thousand years or even tens of thousands of years of protection still can't change the ending of its life element exhaustion." ”

"Oh. Mu Hanyan replied softly, and his expression was even more sad.

"It's not impossible, it is said that a long time ago, there was a treasure called Spirit Rune in the Holy Court Continent, with all kinds of magical powers, one of which is to gather the qi of heaven and earth, if you can find it, maybe there is a chance to hatch. Mu Ruian didn't want to see her daughter disappointed and sad, so she couldn't help but comfort her.

"Where can I find the spirit rune?" Mu Hanyan perked up as Ma asked.

"I'm afraid...... I'm afraid it's not too early, it is said that the spirit rune is not a thing of our Holy Court Continent, but like meteorite, it comes from outside the nine heavens, so the number is extremely rare, and more importantly, the people who first discovered the spirit rune did not understand its wonderful use, and wasted too much, and then after repeated practice, they knew what the use of this spirit rune was. It is said that the current alchemy and formation mechanism techniques of our Holy Court Continent, and even the art of elixir are all derived from the extremely clever predecessors of the ancient times with the help of those few remaining spirit runes.

Up to now, the Holy Court Continent is afraid that it is not easy to find even the last spirit rune...... "Although I don't want my daughter to be too sad, I can't give her a wish that can never be realized, so Mu Rui'an thought about it and said euphemistically." It's not easy to find, it's not at all, where can I find it?

But as he spoke, his voice became smaller and smaller, and his eyes straightened a little as he looked at the strange beast egg.

"What's the matter?" Mu Hanyan was a little worried when he saw his father's startled appearance.

"Impossible, impossible, this ...... Isn't this the legendary spirit rune, look at this breath, it should have only been blessed for a short time, it definitely won't be the original, where did you get it?" Mu Rui'an pointed to the Rui beast egg and said in shock.

"What talisman?" Mu Hanyan looked at the Rui beast egg suspiciously, only to find that the original wonderful pattern had a complex and profound pattern, as if it contained endless mysteries.

Mu Hanyan was also a little puzzled, since she was smashed on the head by this Rui beast egg, she has been keeping it close to her, and she has never left her body at all, how can there be such a so-called talisman.

"Could it be Ye Yanran?" Mu Hanyan was the first to think of her. But recalling the scene at that time, Ye Yanran didn't do anything at all, besides, in her situation at that time, how could she still have the strength to use any spirit runes?

Mu Hanyan looked at the talisman carefully, how could he feel a little familiar, and suddenly an idea moved in his mind, and he reached out and touched it.

The beautiful jade that Ling Baobao gave him, although she didn't look closely, she still had a little impression, wasn't the natural lines in it very similar to this so-called talisman?

Mu Rui'an noticed the change in her expression, knew what she was thinking, and looked at her with good and expectation, but saw that she looked slightly stunned, and then withdrew her head and spread out her palm, revealing a handful of fine jade.

Mu Hanyan didn't know when this jade had been shattered into slag, and he couldn't verify his guess carefully.

"Spirit rune, it's really a spirit rune, where did you get it?" To her surprise, seeing this handful of jade slag, Mu Rui'an was like a treasure, and asked in surprise when she held it in her hand.

"Dad, are you sure this is a spirit rune?" Mu Hanyan was a little suspicious, it was just a handful of jade slag, how could he be so sure of a spirit rune?

More importantly, how could Ling Baobao's body have a spirit rune?

"There will be absolutely no mistake, it is rumored that this spirit rune can only be refined with the best jade, plus the blood of the divine beast, and the method of use is extremely simple, as long as it is crushed, and some spirit runes are of extremely high grade, as long as they meet the conditions, they can even be triggered by themselves without using their hands. Look at this jade, although it is broken into slag, if you feel it carefully, you can still feel the power of its divine beast. Mu Ruian said affirmatively.

Mu Hanyan felt it carefully, and sure enough, as the jade broke, a mysterious and majestic qi was released, although it was extremely subtle, it was very similar to the breath of the poor divine beast.

I really didn't expect that what Ling Baobao handed over to him turned out to be a spirit rune.

"Is it possible that with this spirit rune, the eggs of the Rui Beast can hatch?" Mu Hanyan couldn't hold back the surprise in his heart, and asked Mu Rui excitedly.
