The Skyheart Stone was quietly placed beside Ling Xiao. This Skyheart Stone was as big as a few heads, it was definitely considered big, and if placed there, it would almost reach Ling Xiao's waist!

Looking at the Skyheart Stone in front of him, Ling Xiao was very excited. In the past ten days of running, wasn't they surrounding the Skyheart Stone in front of them? Furthermore, even now he did not know how to use this piece of Skyheart Stone. If not for his own master, perhaps he would really be staring at this treasure mountain.

"Hehe, don't be in such a rush, if you want to refine Skyheart Stone, you'll need to make some other preparations this time. Also, you need to use this refining process to completely raise your cultivation to the limits of your Metamorphosis Secret Realm, so that you can have something to rely on in the next stages of the dry elemental secret area, because this time, some of the students who enter will definitely advance to Supreme Secret Realm, or even half-step Zhi Zun. Reincarnation Grandmaster had his own plans.

"That's right, his strength is low. In this world, it's really difficult!" Ling Xiao himself knew this!

"Oh right, Master, what other preparations do you need to make to refine this Skyheart Stone?" Ling Xiao asked.

"Although we may not be able to use these preparations, we still need to prepare for them!" "Next, do as I say!" Reincarnation Grandmaster reminded Ling Xiao.

Ling Xiao secretly nodded, and then looked at this piece of Skyheart Stone fervently.

"To refine this Skyheart Stone, the first step is to set up a Nine Revolving Lock Immortal Seal, Nine Inverse Dragon Confinement Formation, Nine Secret Divine Seal, Nine Tribulations Thunder Emperor's Seal, Nine Spirit Confinement Formation, Nine Transformations Mysterious Illusion Seal, Nine Heavens Holy Emperor Seal, Nine Nirvana Formation, Nine Deadly Sacred Ancestral Seal!" Reincarnation Grandmaster now told Ling Xiao about nine different types of Inhibition Formations!

"What?" Master, are you sure you're not mistaken? Does this Skyheart Stone really need so many restrictions to seal? " Ling Xiao was truly shocked at this moment. He had only ever seen the Nine Revolutions Lock Immortal Formations, this was his first time hearing of them!

Especially the fact that there were a total of three groups inside, the Forbidden Spell and the Seal, Ling Xiao was at a loss of what to do.

"Cough cough. Of course not. I only need three of the nine formations, but I need one of them. One restriction, one seal, one seal!" Reincarnation Grandmaster also knew that Ling Xiao couldn't accept it all of a sudden.

"Master, what, what are these nine types of things?" Ling Xiao was completely dumbstruck. Until now, Ling Xiao finally knew that he was still just a rookie!

"The nine seals that I mentioned earlier are known as the Nine Great Seals! Each of these sealing marks could be considered the creation of good fortune for Heaven and Earth. These nine sealing marks were not created by humans, but rather, created by nature! The Reincarnation Grandmaster continued to tell Ling Xiao.

"It can't be, could it be that the Nine Revolutions Immortal-Sealing Hex that I saw before was also innate?" Ling Xiao recalled the gigantic restriction she had encountered before!

"However, don't worry. I, your Master, am not fooling around for nothing. Although it's impossible to gather all nine great sealing marks, I still understand three or four of them!" I'll pass it to you! " Reincarnation Grandmaster now passed on to Ling Xiao the four seals that he himself understood.

"Oh my god, Master, you're too amazing! Nine Dragons Confinement Formation, Nine Secret Divine Seal, Nine Tribulations Thunder Emperor's Seal, Nine Transformations Profound Illusion Seal!" Ling Xiao was now aware of the four great sealing marks that his master possessed.

However, although there was a lot of information, it was not an existing seal and there were simply not enough Sealing Power s inside!

After that, Ling Xiao used the Sealing Power to dissolve, analyze, and in a short period of time, Ling Xiao had completely grasped these four seals. After he finished setting them up, Ling Xiao continued to ask: "Master, what next? "What should we do?"

"The second step is to bind it with blood! You can do it yourself! " Reincarnation Grandmaster's voice sounded from the bottom of Ling Xiao's heart.

Right now, Ling Xiao's entire room was already impregnable, it was indestructible, and he was not afraid of being investigated at all, thus he also let go of this bold method of refining!

After forcing out a stream of blood essence, it slowly dripped into the Skyheart Stone.

But in the blink of an eye, it disappeared. There was no response.

"Master, what's going on?" Ling Xiao asked, puzzled.

"Maybe the Skyheart Stone has a seal on it, you should check it first before recognizing it as master!" The Reincarnation Grandmaster spoke.

Therefore, the Sealing Power circulated in Ling Xiao's hands, and when the Sealing Power approached the Skyheart Stone, the Skyheart Stone began to fiercely resist. Ling Xiao knew, the seal that sealed the Skyheart Stone must be struggling.

Immediately, Ling Xiao became overjoyed, and increased the Sealing Power. At this time, Ling Xiao could also feel that her own Sealing Power was rapidly increasing, and was about to break through to the late stage of the Profound Rank!

However at the very last moment, he suddenly stopped. Ling Xiao sighed inwardly, knowing that his soul energy had not reached the level of Supreme Secret Realm yet!

However, this was already pretty good. Following that, the resistance from the Skyheart Stone grew smaller and smaller, and after a while, the Skyheart Stone stopped struggling. Instead, it quickly flew around Ling Xiao's room, as if it wanted to break through the sky.

But after probing for a long time, whenever the Skyheart Stone came close to the outside, Ling Xiao's nine great seals would take effect, rebounding the Skyheart Stone inside. Seeing this, Ling Xiao was overjoyed, and knew that the previous set up by the Reincarnation Grandmaster was indeed very useful.

After the struggle to no avail, the Skyheart Stone finally became obedient. Furthermore, the drop of blood essence that Ling Xiao had dropped into earlier also began to show its effects. In the end, the Skyheart Stone stayed by Ling Xiao's side.

"Master, what a mystical Skyheart Stone, it actually has its own consciousness!" Ling Xiao was very excited as he looked at the Skyheart Stone. The more intelligent the Skyheart Stone, the higher the value of this piece of Skyheart Stone!

"That's right, you should hurry up and refine it!" The Reincarnation Grandmaster spoke.

After that, Ling Xiao did not speak anymore, and placed both his hands on the Skyheart Stone instead. Circulating both Divine Seal of Primal Chaos and primordial meridian, the two most primal auras quickly attracted the Skyheart Stone and the Skyheart Stone was no longer struggling, lying there quietly.

At this time, Ling Xiao could clearly hear the heartbeats coming from the Skyheart Stone, it was almost like his own heart, at the beginning, it was very weak, but after following Ling Xiao's continuous refinement, the heartbeats became louder and louder, soon it matched up to Ling Xiao's heartbeat!

And it was at this moment that a bizarre image appeared in Ling Xiao's mind. It was a greyish patch of nothingness, without anything at all, and after an unknown amount of time had passed, a sudden boom could be heard and an intense explosion occurred in this greyish patch of space. Following that, a large empty patch of space appeared around him.

After that, the space became larger and larger, and slowly, more and more planets from the continent appeared. And right at the center of all these spaces was a stone the size of a few human heads.

In the end, it formed a complex pattern in Ling Xiao's mind, and at this moment, Ling Xiao's eyes slowly opened!

"Since you have comprehended it from the Skyheart Stone, then this move shall be called Heavenly Heart Seal!" Ling Xiao was pleasantly surprised.

After refining the Skyheart Stone, Ling Xiao could feel a bizarre wave coming from the Skyheart Stone.

"Master, it has been refined! "What should we do?" Ling Xiao asked.

"Very good. The third step, is to take out a drop of the Heavenly Heart Source, then absorb it yourself and refine it into your own energy. Then, you will officially break through the limits of your Metamorphosis Secret Realm!" Reincarnation Grandmaster's voice sounded again.

After that, Ling Xiao followed Reincarnation Grandmaster's instructions and took out a single drop of Heavenly Heart Source. At this time, the Heavenly Heart Source was a single drop of green liquid that was emitting dense undulations, and Ling Xiao unhesitatingly swallowed it without any hesitation!

"AHH!" "It hurts, it hurts!" Ling Xiao suddenly shouted.

What kind of pain was that! It was as if thousands of needles were stabbing him, causing Ling Xiao to almost faint from the pain.

"Ling Xiao, don't tell me you can't even endure this bit of pain? One must know that for anything that has not been paid, how can there be a reward? " Reincarnation Grandmaster said in Ling Xiao's heart.

"AHH!" There's no way to make me, Ling Xiao, surrender! "AHH!" "Refine it for me!" Ling Xiao shouted.

After that, they saw that Ling Xiao's face had almost become twisted, but Ling Xiao was so stunned that he did not say a single word. Not long later, Ling Xiao's forehead and back were all drenched with sweat, and his body was also trembling violently.

"Persist!" I, Ling Xiao, must persevere on! Meng Ziyan is still waiting for me, Meng Ru is still waiting for me! Father and the rest are still waiting for me! " Ling Xiao said in his heart again and again.

When the intense pain lasted for half an hour, that feeling finally started to lessen, and finally disappeared, followed by an extremely comfortable feeling that almost made Ling Xiao moan!

"Phew!" Oh my god! It really is the Twin Heavens of Ice and Fire! However, I can be considered to have successfully broken through! Haha, is this the strength of half-step asthenia refinement? It's simply too powerful! " Ling Xiao had finally held on for a while.

Seeing Ling Xiao's current state, Reincarnation Grandmaster was also moved in his heart. For Ling Xiao to have such achievements today, who knew how much pain he had to endure!

At this time, not only his soul force had made a breakthrough, but even the chaos-emperor body had successfully broken through to the limits of his Void Refining Secret Realm.
