Thinking of that terrifying and wonderful experience, Luo Yu was still in turmoil, and suddenly pulled the placket of his chest a little, and an extremely thin curved mark was imprinted on his chest like a birthmark he was born with.

This mark can neither be forcibly forced out of the body, nor can it be refined with the power of true fire, and Luo Yu, the imperial art of Yuan power and spiritual power, has been used all over again, and the result is completely helpless.

Even Luo Yu couldn't even remember when and why this mark appeared, but it was certain that this thing must be related to the magical encounter in the black crystal starry sky.

After all, the black crystal starry sky is related to the law of the black domain, Luo Yu injected the black silk in his body into this position, and he really accidentally discovered that as soon as those black silk squares touched the imprint, they were immediately sucked into the bottomless pit, and it was very different from other mana Yuan Li easily dissolved into the imprint, making the blue light released by the latter slightly brighter, and in an instant, Luo Yu Ling was sensitive to the fact that the Yuan Force in the air outside his body fluctuated slightly for a moment, but it also ended here, after this vision, let Luo Yu inject all the black silk into it, the latter still did not change much.

This scene couldn't help but make Luo Yu a little frustrated, except for finding that this mark could contain Wu Si, it seemed to be useless, the only discovery was extremely useless to Luo Yu, but fortunately, this mark did not have any adverse effect on Luo Yu's body, he didn't have to worry about it.

Putting aside this unsolvable mystery, as long as Luo Yu thought of the benefits of this experience, he was really happy to be called forgetful, and he didn't pay much attention to the imprint.

Luo Yu didn't expect that he really got out of trouble with another wave of black smoke blowing in the black crystal starry sky half a month later, this feeling of life and death was like a dream for him, and Luo Yu still didn't understand what kind of existence the black crystal starry sky was.

But what I have to say, he relied on the mysterious flame to frantically refine the yuan power to cultivate, and in just half a month, it was at least worth Luo Yu's penance in the black domain for several years, and the pleasure of smooth wind and water without the slightest dullness really didn't seem like something that should be in the world.

Of course, if it weren't for Luo Yu's possession of the mysterious flame protector and his ability to assimilate some of the laws of the Black Domain, and freely run into such a deep place underground, he would definitely fall into the danger of death and lifelessness.

Luo Yu suddenly remembered that he could find this extremely mysterious black crystal vein, most of which was based on the black domain map wall painted by Bai Yuan Niangniang, and since the other party was looking for the so-called ice crystal mine, it should have also gone deep into the ground, even if there was no ice crystal mine, in order to find a way to escape, Bai Yuan Niangniang also forcibly opened up a thousand-zhang deep underground passage with a formation, with her cultivation in the infancy stage, didn't she ever discover the secret of the black crystal starry sky?

However, despite this doubt, the irresistible feeling given to Luo Yu by the black crystal starry sky is far better than that of a monk in the face of the Yuan Infant Stage, if Luo Yu does not have the symbiotic induction of the domain power in his body, it is a bit of a needle in a haystack to find it, not to mention that Bai Yuan Niangniang cultivates the way of demon spirits, and the aura of heaven and earth is almost nothing in the black crystal starry sky, and this kind of secret place full of danger and opportunities is not suitable for anyone.

If Bai Yuan Niangniang did not have insight into the operation of the laws of the Black Domain, the underground world was like a vast sea, and it was indeed impossible to find the location of the island-sized black crystal starry sky, when he thought of this, Luo Yu's worries dissipated, after all, anyone who faced such an excellent cultivation place would not be stupid enough to share it with outsiders, let alone a person who could decide his life and death.

Therefore, Luo Yu immediately made up his mind, the secret of the black crystal starry sky must rot to death in his heart, even if he met Bai Yuan Niangniang in it one day, he had to pretend not to know and think of a seamless rhetoric.

Of course, Luo Yu will not have much time to stay in the black crystal starry sky, at most in about a year, he will have to leave with Bai Yuan Niangniang, and the possibility of coming back to the Black Domain in the future is almost zero.

Although it has taken less than a year, with such a rapid cultivation speed, Luo Yu is confident that it is very possible to reach the peak of the early stage of the third order, as for whether he can break through the middle stage of the third order, for Luo Yu, who is practicing the ancient Buddhist sect for the first time, he is completely uncertain in his heart, and he feels a little pity.

It's just that when I made up my mind, I also took a fancy to the many magical powers of the ancient Buddhism when it shook the human world, so this road is destined to be difficult.

In fact, even if he could only cultivate casually in the black crystal starry sky for more than ten years at a time, then Luo Yu felt that it was not impossible to climb to the peak of the third order, and even ascend to the realm of the fourth order of the Yuan Zun in one fell swoop, but in this way, he missed a rare opportunity to leave, between life and cultivation, the former was gone, and no matter how high the cultivation was, what was the use.

If other people know Luo Yu's thoughts at this time, I am afraid that they will be envious until death, it will be difficult for others to encounter such an opportunity in their lives, but Luo Yu is not enough.

But now is not the time to be cranky, this time in the black crystal starry sky is half a month, Luo Yu has not yet had time to cultivate the innate thunder fire that Bai Yuan Niangniang confessed, in case this makes this great supernatural power of the Yuan Infant stage not hide it from him, Luo Yu has no possibility of escaping death for the second time.

According to the agreement between the two of them in advance, Luo Yu asked this woman to check the progress of her cultivation every other month, and under the sharp eyes of the Yuan Infant Cultivator, she couldn't mix it with any fakes.

Suddenly remembering this in his heart, Luo Yu hurriedly untied the storage bag given by Bai Yuan Niangniang from his arms, and after a mouthful of spiritual breath sprayed on it, four white arcs and a blue light shot out at the same time in front of him, and after hovering one after another, he was suspended in front of him under the control of Luo Yu's divine thoughts!

But at this moment, Luo Yu was a little surprised!

The blue light is okay, it is just a simple scroll inside, glowing with a ruler-long glow, most of which records the cultivation method of innate thunder and fire, but the divine thoughts that are equivalent to invisible things are obviously transmitted back a trace of paralysis from being shocked at the moment when they come into contact with the other four white lights!

"This is the innate thunder crystal?" Luo Yu's gaze hovered a little strangely on the four fist-sized electric lights, and the power of thunder and lightning that could affect the divine thoughts under unconscious conditions was too unbelievable.

Luo Yu didn't do anything rashly, but his consciousness sank, and he doubled the electric light, although the numbness was stronger than before, but Luo Yu forcibly broke the surface arc and showed it.

I saw that there were four pieces of jade-like round things inside, smoky white and translucent, on the smooth and flawless jade, covered with extremely dense cyan reticulated lines, but no matter how you look at it, these lines can be vividly seen as a lot of thunderbolts appearing on the jade jue in a variety of shapes, giving people a feeling of lightning intertwined.

Luo Yu observed all four pieces of jade, and they were almost identical!

Retracting his divine thoughts, Luo Yu's face did not fluctuate in the slightest, but first reached out and grabbed the blue scroll, put it in his eyes and read it carefully.

Before meeting Bai Yuan Niangniang, Luo Yu had never heard of the existence of such spiritual creatures in the world, so everything Luo Yu knew was known from the other party's mouth, but at that time, because Bai Yuan Niangniang only casually mentioned a few words, Luo Yu still had many unknowns.

After about a stick of incense, Luo Yu opened his eyes in surprise, and then his expression became a little surprised.

I don't know if I don't see it, it turns out that there are so many benefits of this law that there are more than what Bai Yuan Niangniang said.

Not to mention anything else, just the origin of these 'Innate Thunder Crystals' made Luo Yu quite frightened, Luo Yu was delusional at first, but he didn't expect that the Innate Thunder Crystals could be traced back to the flood period, so in addition to being a little excited and speechless, I really don't know how to describe it!

It turns out that each innate thunder crystal is the thunder and lightning essence extracted by Bai Yuan Niangniang from the extremely high altitude of the black domain, and the black domain is not as good as the outside world, and the thunder attribute vitality has long been thin and mixed with the great changes in the heavens and the earth that broke out in ancient times, and the thunder aura in the black domain only appeared from the advent of the extraterrestrial fire fall during the flood period, and it has not changed much until now.

Even in the ancient period, the Innate Thunder Crystal had only appeared a few times, and when it came to Luo Yu's current cultivation realm, he had never heard of such a spiritual creature that had been conceived since the Flood Desolation period.

Fortunately, the thunder crystal head seems to be not small, but it only contains a trace of innate thunder and lightning power, otherwise with Luo Yu's current ability, he would never be able to absorb such a terrifying thing into his body.

The four pieces of innate thunder crystals in Luo Yu's hand were carefully calculated by the other party, at most, they could only be used for a month of cultivation, and the other party also made it clear in the exercises, these innate thunder crystals had been sacrificed by her in advance, if Luo Yu lied about the amount consumed every month, he couldn't hide some without permission.

However, Luo Yu faintly saw from the other party's words that it seemed that there were not many innate thunder crystals in Bai Yuanniang's hands, otherwise she would not have been so nervous, but no matter how Luo Yu looked at it, he always felt that the things in front of him were not as big as the other party said.

With the idea of giving it a try in his heart, he pinched his hands, Luo Yu opened his mouth and spewed out a mouthful of pure three-color true fire, and then opened his mouth, and blew a breath of aura on this fire, in the colorful waves of fire rolling, a three-color firebird seemed to fly out, Luo Yu saw that the firebird's face was condensed, his hands flipped quickly, and a variety of different forms of magic tricks flew out one after another, and he recited an obscure spell that he had never heard before.

After spending a cup of tea, all the aura around the three-color firebird finally condensed into a cyan lightning mark, and imprinted on the center of the firebird's eyebrows in a flash, Luo Yu was a little relieved when he saw this, he didn't expect that the initial induction of the 'Innate Thunder Fire' was much more complicated than the ordinary middle-level spell, and it was really created by the Yuan Infant Cultivator.

However, the binding spirit has been completed, and as soon as Luo Yu Shennian issued another order, the three-colored firebird suddenly let out a clear roar and swooped towards one of the pieces of jade.

This three-color firebird has no fear at all, a large mouth full of flames, and surprisingly successfully swallowed Yu Jue into its abdomen, and then a pair of fire-eyed cyan lightning flashes generously, and a ** white electric tide gushes out of the body like a thousand holes, both of them look like they are about to break free at any time, these signs are about to explode, but Luo Yu just calmed down after being startled.

Because above the three-color firebird connected by his heart, Luo Yu instead sensed an extremely soothing and gentle aura.

According to the introduction of the Jade Jian Gong Method, when it comes to this step, Luo Yu must immediately swallow this innate thunder crystal covered by true fire, and then promote the two to become one in his body according to the law, as fast as two or three days, slow as no more than seven days, no matter how bad Luo Yu's qualifications are, he can refine four thunder crystals within a month.

It's just that at the moment, Luo Yu hesitated, recklessly swallowed such a terrible thing, and let it stay in his body for a period of time, he had to grow a few more eyes.

Luo Yu couldn't verify the origin of the innate thunder crystal, but any kind of innate thunder and lightning power between heaven and earth must be the nemesis of most of the demonic evil arts in the world, and the innate thunder crystal is second to none.

Luo Yu suddenly changed his hand, and a trace of black gas as thin as a hair was raised to beat his hand, Luo Yu had to sigh at the power of the laws of the black domain, although he was not a real demon cultivator, but he had also read a lot of magic classics, and the magic and ghost arts that were usually brought at hand were also a little hot, but in the black domain, the power was too cold.
